    To compare the prognosis of patients with advanced-stage primary peritoneal serous papillary carcinoma (PSPC) or papillary serous ovarian cancer (PSOC). This was a retrospective case-control study and included two study groups: one with stage III/IV PSPC (n = 38) patients and the other with PSOC (n = 53) patients. Patients were matched for histologic subtype (serous tumor), tumor stage, tumor grade, residual disease at the end of debulking surgery (primary or interval), and age (±5 years). Mean age was significantly greater for patients with PSPC (63.03 ± 11.88 years) than for patients with PSOC (55.92 ± 12.56 years, p = 0.008). Optimal debulking surgery was performed initially in 71.9% of PSPC patients and 66.0% of PSOC patients. In addition, 93.9% of PSPC patients and 92.3% of PSOC patients were treated with platinum-paclitaxel chemotherapy. The frequency of high-grade tumors was significantly higher in the PSPC (100%) than in the PSOC group (68.3%; p statistic). PFS was similar for advanced-stage PSPC and PSOC patients. Since the PSPC patients tended to be older and have more high-grade tumors, OS was shorter for PSPC than for POSC patients. Thus, management of the two types of cancer should not differ.

    Full Text Available Introduction. Reports of epithelial ovarian carcinomas metastatic to the pancreas are very rare. We herein present a metastasis of high grade papillary serous ovarian cancer to mid portion of pancreas. Case. A 42-year-old patient was admitted with a non-specified malignant cystic lesion in midportion of pancreas. She had a history of surgical treatment for papillary serous ovarian adenocarcinoma. A cystic lesion was revealed by an abdominal computerized tomography (CT performed in her follow up . It was considered as primary mid portion of pancreatic cancer and a distal pancreatectomy was performed. The final pathology showed high-grade papillary serous adenocarcinoma morphologically similar to the previously diagnosed ovarian cancer. Discussion. Metastatic pancreatic cancers should be considered in patients who present with a solitary pancreatic mass and had a previous non-pancreatic malignancy. Differential diagnosis of primary pancreatic neoplasm from metastatic malignancy may be very difficult. A biopsy for tissue confirmation is required to differentiate primary and secondary pancreatic tumors. Although, the value of surgical resection is poorly documented, resection may be considered in selected patients. Conclusion. Pancreatic metastasis of ovarian papillary serous adenocarcinoma has to be kept in mind when a patient with pancreatic mass has a history of ovarian malignancy.

    Full Text Available Primary carcinoma of the fallopian tube is rare and accounts for about 0.14-1.8% of all gynecological malignancies. Correct diagnosis is rarely made preoperatively as clinically tubal carcinoma closely resembles ovarian carcinoma. Here, we report two cases of bilateral primary fallopian tube carcinomas. Case 1: A 54-year-old female presented with postmenopausal bleeding, abdominal pain, and pervaginal watery discharge for 10 days. Ultrasonography (USG of pelvis showed endometrial thickening and multiple tiny echogenic foci in omentum suggestive of omental cake. With a provisional diagnosis of endometrial carcinoma, total abdominal hysterectomy with bilateral salpingo-oophorectomy and omentectomy was done. On gross examination, small and rudimentary right ovary was adherent to the fimbrial end of the tube. Left-sided tubo-ovarian mass was present, cut section of which showed yellowish solid area in tubal wall and encroaching on ovarian surface. On histological examination, sections from the fimbrial end of both fallopian tubes showed features of papillary serous adenocarcinoma. Case 2: 70-year-old lady, 15 years postmenopausal presented with gradual onset pain and swelling of abdomen, urinary incontinence since 4 days. USG showed bulky uterus, 5 cm × 2 cm fibroid, bilateral tubes, and ovaries were not visualized. Serum cancer antigen-125 was raised (159.7 U/ml. Total hysterectomy and bilateral salpingo-oophorectomy with infracolic omentectomy was done. On gross examination, ovaries were firmly attached to tubes and no apparent solid area was noted. On microscopy, papillary serous adenocarcinoma arising from tubal wall was seen infiltrating focally into ovarian stroma; tubal epithelium showed dysplastic change. Sections from omentum showed numerous psammoma bodies.

    Full Text Available We present a case report of a 47-year-old woman who was admitted to our University-Hospital following diagnosis of pelvic mass. Abdominal examination revealed a tender, palpable mass on the right iliac region. At the gynecological examination uterus was regular in size. On the left side of the uterus a mass of 9 cm was observed; its surface was irregular and no mobility was found. Abdominal CT and NMR revealed massive ascites, omental cake and increased volume of both ovaries. Patient underwent longitudinal suprombelical-pubic laparotomy. After opening abdominal cavity, a free-fluid sample was taken and the results were positive for malignant cells. Typical neoplastic localizations on both ovaries, Douglas’ peritoneum, rectum, sigmoid colon and omentum were observed. Extemporaneous histological examination diagnosed a peritoneal serous papillary carcinoma. Hysterectomy with salpingo oophorectomy, total omentectomy, appendectomy, pelvic and lumbo-aortic lymphadenectomy was performed. Retroperitoneal approach to remove the whole Douglas’ peritoneum together with the pouch malignant localizations was done. Sigmoid colon and rectum were resected. A latero-terminal anastomosis with stapler was performed. All the visible abdominal maligant lesions were cut out. No transfusion was necessary. The postoperative course was regular and after seven days the patient was discharged. Chemotherapy ended the therapeutic management (six cycles of carboplatin and paclitaxel. After one year the patient is in good health and instrumental investigations (Ultrasounds, TC and NMR are negative for recurrence. Such a case is very interesting for the discrepancy between slight symptoms and severity of the disease, the solution of which was very complex requiring a skillful polyspecialized oncological team.

    BACKGROUND There is now evidence to support that some cases of high-grade serous papillary carcinoma arise from the fallopian tubes rather than the ovaries. Common symptoms at presentation include abdominal pain and swelling, vomiting, altered bowel habit and urinary symptoms. To our knowledge, this is the first case of serous papillary carcinoma presenting as a vaginal mass lesion. CASE REPORT A 41-year-old woman was referred to the Bnai-Zion Medical Center with the main complaint of irregular vaginal bleeding, vaginal mucous discharge, and suspected pelvic mass. Physical examination showed a soft, painless mass, measuring about 10 cm in diameter located mainly in the recto-vaginal septum, but not involving the uterus. Ultrasound examination showed no abnormal ovarian or uterine findings. Transvaginal biopsies of the mass showed a poorly differentiated serous papillary carcinoma of ovarian, tubal, or peritoneal origin. The physical examination and imaging findings strongly indicated an inoperable tumor, and the patient was treated with neoadjuvant (pre-surgical) chemotherapy. Pre-operative computed tomography (CT) imaging showed the partial involvement of the colon, and so surgical treatment included total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, partial vaginectomy, anterior rectal resection, and lymph node dissection. Histopathology of the surgical specimens showed a poorly differentiated serous carcinoma originating from the fimbria of the right fallopian tube. CONCLUSIONS To the best of our knowledge, this is the first report to describe primary fallopian tube papillary serous carcinoma presenting as a vaginal mass. Therefore, physicians should be aware of this possible diagnosis.

    Full Text Available Abstract Background Women that carry germ-line mutations for BRCA1 or BRCA2 genes are at an increased risk of developing breast, ovarian and peritoneal cancer. Primary peritoneal carcinoma is a rare tumour histologically identical to papillary serous ovarian carcinoma. Risk-reducing surgery in the form of mastectomy and oophorectomy in premenopausal women has been recommended to prevent breast and ovarian cancer occurrence and decrease the risk of developing primary peritoneal cancer. Case presentation We present a case report of a woman with a strong family history of breast cancer who underwent risk-reducing surgery in the form of bilateral salpingo-oophorectomy following a mastectomy for a right-sided breast tumour. Following the finding of a BRCA1 mutation, a prophylactic left-sided mastectomy was performed. After remaining well for twenty-seven years, she presented with rectal bleeding and altered bowel habit, and was found to have a secondary cancer of the sigmoid colon. She was finally diagnosed with primary papillary serous carcinoma of the peritoneum (PSCP. Conclusion PSCP can present many years after risk-reducing surgery and be difficult to detect. Surveillance remains the best course of management for patients with known BRCA mutations.

    To date, this is the first report to monitor changes of intratumor vascularization and the response to radiation and Cyberknife therapy in a patient with recurrent primary papillary serous carcinoma of the peritoneum by three dimensional (3D) power Doppler ultrasonography (PDUS). Transvaginal 3D PDUS detected a recurrent presacral tumor with abundant intratumor vascularity. Serial examinations of the tumor volume and serum CA-125 level were studied before, during, and 6 mo after therapy. Meanwhile, the intratumor blood flow was measured and expressed as vascularity indices. All of the tumor volume, intratumor vascularity indices and serum CA-125 level decreased progressively following therapy. A remaining lesion with nearly absent intratumor power Doppler signals suggested a scarring lesion posttreatment. Indeed, CT-guided tissue biopsy confirmed fibrotic change. 3D PDUS is useful to monitor the response to treatments and to differentiate residual tumors from lesions of scarring change posttreatment. It provides more accurate posttreatment information than pelvic computed tomography.

    A normal-sized ovarian papillary serous carcinoma is rare. We present the case of a 46-year-old woman with progressive abdominal fullness of one week's duration. The medical evaluation revealed abdominal carcinomatosis with normal-sized ovaries and an elevated serum CA-125 level of 147,365.8 U/ml. Cytoreductive surgery (hysterectomy, bilateral salpingo-oophorectomy, omentectomy, lymphadenectomy, infracolic omentectomy, peritoneal biopsy, washing cytology, and appendectomy) was performed. The histologic examination revealed an ovarian serous papillary carcinoma. Adjuvant chemotherapy was administered. The serum CA-125 level decreased after completion of treatment. Normal-sized ovarian serous surface papillary carcinomas should be kept in mind as an origin of disease in patients who have peritoneal carcinomatosis, which sometimes is a diagnostic dilemma of the disease source. We report this case to emphasize the clinical symptoms and importance of the early and accurate diagnosis of a normal-sized ovarian papillary serous carcinoma.

    A female golden retriever was referred to assess a history of a palpable abdominal mass. A serum chemistry analysis revealed elevated concentrations of blood urea nitrogen, creatinine, calcium, and parathyroid hormone-related protein (PTH-rP). Exploratory laparotomy revealed an ovoid mass within the right ovary. This mass was removed surgically by performing an ovariohysterectomy. The right ovarian mass was diagnosed as a serous papillary adenocarcinoma. Following surgery, the dog recovered, and the serum calcium and PTH-rP concentrations decreased. Therefore, concentrations of PTH-rP and calcium might be associated with serous papillary adenocarcinomas. Serial evaluation of the serum PTH-rP and calcium was useful for evaluating the prognosis.

    Borderline epithelial ovarian tumours (BOT) represent 15–20% of all non-benign ovarian epithelial neoplasms. Compared to malignant ovarian tumours, they usually present at a younger age and carry a far superior prognosis. Fertility-conserving surgery is an important treatment option for patients with BOT. Ultrasound and CT are both widely available and play roles in the initial investigation and staging of BOT, respectively. However, lack of soft-tissue contrast limits their ability to characterize BOT. MRI can facilitate recognition of pure epithelial serous BOT (SBOT), including the cystic papillary and surface papillary subtypes. An abundance of hyperintense papillary projections with low signal internal branching and ovarian stroma preservation with a hypointense ovarian capsular margin on T2-weighted imaging are features strongly suggestive of SBOT. In this review we will discuss the general morphological features of SBOT, the benefits and drawbacks of ultrasound and CT in the initial work-up, and the principal MRI features enabling recognition of surface papillary and cystic papillary SBOT

    Primary carcinoma of the vermiform appendix is a rare disease with few clinical symptoms. Accordingly, preoperative diagnosis of appendiceal cancer is challenging because of the lack of specific symptoms. We herein report a case of appendicular adenocarcinoma found unexpectedly during laparoscopic surgery in a 69-year-old Japanese female patient diagnosed with serous papillary adenocarcinoma, in order to determine whether optimal cytoreduction could successfully be achieved at the time of primary surgery. We performed diagnostic laparoscopic surgery in order to make a correct diagnosis based on the histological tissue. The vermiform appendix was found to contain a tumor measuring 1.5 cm wide and 4.5 cm long. Laparoscopic appendectomy, partial omentectomy, and partial resection of the lesion in the peritoneum were performed. The histological diagnosis was mucinous adenocarcinoma of the vermiform appendix, and the stage was T4NxM1. The patient received adjuvant chemotherapy with mFOLFOX 6 (5FU, leucovorin, and oxaliplatin). She achieved stable disease and was alive with disease eleven months after surgery. We therefore recommend that gynecologists should not rule out the possibility of appendiceal cancer, even in cases with preoperative findings similar to those of serous papillary adenocarcinoma of the peritoneum with peritoneal disseminated tumors.

  15. Papillary Tubal Hyperplasia. The Putative Precursor of Ovarian Atypical Proliferative (Borderline) Serous Tumors, Noninvasive Implants and Endosalpingiosis

    In contrast to the controversy regarding the terminology and behavior of ovarian noninvasive low-grade serous tumors (atypical proliferative serous tumor [APST] and serous borderline tumor [SBT]), little attention has been directed to their origin. Similarly, until recently, proliferative lesions in the fallopian tube have not been extensively studied. The recent proposal that ovarian high-grade serous carcinomas are derived from intraepithelial carcinoma in the fallopian tube prompted us to evaluate the possible role of the fallopian tube in the genesis of low-grade serous tumors. We have identified a lesion, designated “papillary tubal hyperplasia (PTH)”, characterized by small rounded clusters of tubal epithelial cells and small papillae, with or without associated psammoma bodies, that are present within the tubal lumen and which are frequently associated with APSTs. Twenty-two cases in this study were selected from a population-based study in Denmark of approximately 1000 patients with low-grade ovarian serous tumors in whom implants were identified on the fallopian tube. Seven additional cases were seen recently in consultation at The Johns Hopkins Hospital (JHH). These 7 cases were not associated with an ovarian tumor. Papillary tubal hyperplasia was found in 20 (91%) of the 22 cases in the Danish study. Based on this association of PTH with APSTs with implants and the close morphologic resemblance of PTH, not only to the primary ovarian APSTs but also to the noninvasive epithelial implants and endosalpingiosis, we speculate that the small papillae and clusters of cells from the fallopian tubes implant on ovarian and peritoneal surfaces to produce these lesions. The 7 JHH cases of PTH that were not associated with an ovarian tumor support the view that PTH is the likely precursor lesion. We propose a model for the development of ovarian and extraovarian low-grade serous proliferations (APST, noninvasive epithelial implants and endosalpingiosis) that

    A diagnosis of primary peritoneal serous carcinoma (PPSC) requires exclusion of a source in other reproductive organs. Serous tubal intraepithelial carcinoma (STIC; stage 0) has been described in asymptomatic women with BRCA mutations and linked to a serous cancer precursor in the fimbria. This study examined the frequency of STIC in PPSC and its clinical outcome in BRCA-positive women. Presence or absence of STIC was recorded in consecutive cases meeting the 2001 WHO criteria for PPSC, including 26 patients with nonuniform sampling of the fallopian tubes (group 1) and 19 patients with complete tubal examination (group 2; sectioning and extensively examining the fimbriated end, or SEE-FIM protocol). In selected cases, STIC or its putative precursor and the peritoneal tumor were analyzed for p53 mutations (exons 1 to 11). Outcome of STIC was ascertained by literature review. Thirteen (50%) of 26 PPSCs in group 1 involved the endosalpinx, with nine STICs (35%). Fifteen (79%) of 19 cases in group 2 contained endosalpingeal involvement, with nine STICs (47%). STIC was typically fimbrial and unifocal, with variable invasion of the tubal wall. In five of five cases, the peritoneal and tubal lesion shared an identical p53 mutation. Of 10 reported STICs in BRCA-positive women, all patients were without disease on follow-up. The fimbria is the source of nearly one half of PPSCs, suggesting serous malignancy originates in the tubal mucosa but grows preferentially at a remote peritoneal site. The generally low risk of recurrence in stage 0 (STIC) disease further underscores STIC as a possible target for early serous cancer detection and prevention.

    Full Text Available A 77-year-old female was presented to the emergency department with intense anorexia, weight loss despite progressive abdominal distension, and dyspnea. Abdomen imagiology workup reveled moderate-volume ascites and a hepatic occupying lesion. Diagnostic paracentesis allowed the drainage of a chylous effusion and cytology analysis identified adenocarcinoma cells. Hepatic metastasis of papillary serous adenocarcinoma of the endometrium was confirmed after tomography-guided biopsy. Endometrial carcinoma is the most common malignant gynecological neoplasm in developed countries and is often classified in types I with endometrioid histology (estrogen-dependent and non endometrioid types II (non-estrogen-dependent. Chylous ascites or chylaskos is a rare presentation on hospital admission. Several etiologies have been described. In adults, solid malignancy is expected to be identified in less than 20% of the cases. A systematic review has found only one case of endometrial carcinoma presenting with chylous ascite. As far as we know, this is the first case report of a serous papillary adenocarcinoma of the endometrium presenting with chylaskos.

    Full Text Available Serous papillary cystadenofibromas (SPCAFs of the fallopian tube are very rare benign tumors of the female genital tract. They are usually asymptomatic and are found incidentally. Until now, only 18 cases of this tumor have been reported in the world literature. We report a case of SPCAF of the left fallopian tube in a 30-year-old female who presented with a large abdominal mass and pain. On computed tomography, a diagnosis of ovarian neoplasm was given. However, during surgery the tumor was found to arise from the fallopian tube and was treated with tubal cystectomy with sparing of the ovary. We present this unique case on account of its rarity, unusual presentation, and huge size along with a short review of literature.

    Full Text Available Primary peritoneal serous carcinoma (PPSC is a rare primary malignancy that diffusely involves the peritoneum, indistinguishable clinically and histopathologically from primary serous ovarian carcinoma. The origin of PPSC has not been well characterized. Here we present a case of PPSC diagnosed in ultrasonography-guided fine needle aspiration cytology (FNAC in a 76- old female presenting with ascites, abdominal pain, distension and constipation. PPSC is an unusual tumour but cytomorphology is distinctive enough to diagnose preoperatively. In the case report hereby described PPSC is an inoperable malignancy, hence chemotherapy and palliative care are the only offered treatment.

    1996-01-01

    Objective: The optimum adjuvant therapy for uterine papillary serous carcinoma (UPSC), a rare but clinically aggressive histologic variant of endometrial carcinoma, is a controversial issue. UPSC behaves in a pattern that resembles the papillary serous carcinoma of the ovary with a tendency to spread to the peritoneal surfaces. Whole abdominopelvic irradiation (WAI) has been advocated but it remains unclear if adjuvant pelvic irradiation alone is sufficient for early stage UPSC. We reviewed our experience in the adjuvant radiation treatment for UPSC treated at our institution. Materials and Methods: Between 1985 and 1995, a series of 351 cases of endometrial carcinoma were referred to the department of Radiation Oncology. There were a total of 26 UPSC cases with 25 medical records available for review. Except for one case which received irradiation alone, the remaining 24 cases were all surgically staged with TAH/BSO. These patients were treated with WAI or pelvic irradiation with or without a vaginal cuff boost using brachytherapy. The irradiation treatment fields, dose, the local/regional and distant disease status at last follow-up were recorded. The medium follow-up interval was four years with a range of one to eight years. Kaplan-Meier plots for disease specific survival and local/regional disease free survival were obtained. Results: Of the 25 surgically staged UPSC patients, the stage distribution was as follows: 9 stage I, 4 stage II, 10 stage III, and 2 stage IVB. Twelve patients received WAI (4 stage I disease, and 8 stage III disease), while the remaining patients were treated with pelvic irradiation (XRT). 1.) 13 patients were alive without disease and 3 were alive with disease. Seven patients died of either distant metastasis or abdominal recurrence and two died of intercurrent disease (5 year disease specific survival for the whole group was 43%). Two of 17 patients with stages IIIA and below vs. five of 8 patients with stages IIIB and above died of

    Angiogenesis is a hallmark of ovarian cancer (OC); the ingrowth of blood vessels promotes rapid cell growth and the associated metastasis. Melatonin is a well-characterized indoleamine that possesses important anti-angiogenic properties in a set of aggressive solid tumors. Herein, we evaluated the role of melatonin therapy on the angiogenic signaling pathway in OC of an ethanol-preferring rat model that mimics the same pathophysiological conditions occurring in women. OC was chemically induced with a single injection of 7,12-dimethylbenz(a)anthracene (DMBA) under the ovarian bursa. After the rats developed serous papillary OC, half of the animals received intraperitoneal injections of melatonin (200 µg/100 g body weight/day) for 60 days. Melatonin-treated animals showed a significant reduction in OC size and microvessel density. Serum levels of melatonin were higher following therapy, and the expression of its receptor MT1 was significantly increased in OC-bearing rats, regardless of ethanol intake. TGFβ1, a transforming growth factor-beta1, was reduced only after melatonin treatment. Importantly, vascular endothelial growth factor (VEGF) was severely reduced after melatonin therapy in animals given or not given ethanol. Conversely, the levels of VEGF receptor 1 (VEGFR1) was diminished after ethanol consumption, regardless of melatonin therapy, and VEGFR2 was only reduced following melatonin. Hypoxia-inducible factor (HIF)-1α was augmented with ethanol consumption, and, notably, melatonin significantly reduced their levels. Collectively, our results suggest that melatonin attenuates angiogenesis in OC in an animal model of ethanol consumption; this provides a possible complementary therapeutic opportunity for concurrent OC chemotherapy.

    Introduction: Uterine papillary serous carcinoma (UPSC) is a morphologically distinct variant of endometrial carcinoma that is associated with a poor prognosis, high recurrence rate, clinical understaging, and poor response to salvage treatment. We describe the presentation, local and distant control, survival, salvage rate, and complications for patients undergoing whole abdominal radiation therapy (WART), low dose rate (LDR) intracavitary brachytherapy, or high dose rate (HDR) vaginal brachytherapy in patients with stage I UPSC. Methods: Between 1976 and 1994 more than 1700 patients with endometrial carcinoma were treated with radiation therapy, 30 patients with stage I UPSC (1.8%) were treated with radiation before or following TAH/BSO. All patients underwent either preoperative Simon's packing or tandem and plaque which delivered 30-40 Gy to the serosa, WART, or HDR Ir-192 vaginal apex brachytherapy to a total dose of 21 Gy in 3 fractions at 0.5 cm from the vaginal mucosa. A total of 14 patients received HDR vaginal brachytherapy and (5(14)) patients received systemic chemotherapy. All patients presented with vaginal bleeding at a median age of 67 years (range 34-88). The group of 30 patients underwent TAH/BSO, 17 patients were completely staged pathologically (pelvic and para-aortic lymph nodes, omentectomy, and pelvic washings), and 2 patients underwent omental biopsy and pelvic washings only. All specimens revealed UPSC, nuclear grade 3, and lymphovascular invasion (23%). The pathologic stage was IA: 23% (7), IB: 67% (20), and IC: 10% (3). The median follow-up for all patients was 49 months (range 13-187 months). For the patients receiving postoperative HDR vaginal brachytherapy the median time from surgery to radiation was 42 days (range 29-91). Results: The 5-year actuarial disease free survival for Figo stage I UPSC patients treated with postoperative HDR vaginal brachytherapy and systemic chemotherapy was 100% compared to 74% for stage I UPSC patient

    Full Text Available Ovarian cancer is a deadly disease with long latency. To understand the consequences of loss of folliclestimulating hormone receptor (FSH-R signaling and to explore why the atrophic and anovulatory ovaries of follitropin receptor knockout (FORKO mice develop different types of ovarian tumors, including serous papillary epithelial adenoma later in life, we used mRNA expression profiling to gain a comprehensive view of misregulated genes. Using real-time quantitative reverse transcription-polymerase chain reaction, protein analysis, and cellular localization, we show, for the first time, in vivo evidence that, in the absence of FSH-R signaling, claudin-3, claudin-4, and claudin-11 are selectively upregulated, whereas claudin-1 decreases in ovarian surface epithelium and tumors in comparison to wild type. In vitro experiments using a mouse ovarian surface epithelial cell line derived from wild-type females reveal direct hormonal influence on claudin proteins. Although recent studies suggest that cell junction proteins are differentially expressed in ovarian tumors in women, the etiology of such changes remains unclear. Our results suggest an altered hormonal environment resulting from FSH-R loss as a cause of early changes in tight junction proteins that predispose the ovary to late-onset tumors that occur with aging. More importantly, this study identifies claudin-11 overexpression in mouse ovarian serous cystadenoma.

    Primary peritoneal serous carcinoma (PPSC) is a rare neoplasm histologically indistinguishable from ovarian serous carcinoma primarily occurring in the female population. To date, extremely rare cases of PPSC have been reported in men; however, diagnosis by cytology has yet to be described. Here we present the clinical, radiographic, cytomorphologic, histologic and immunohistochemical (IHC) findings of a high-grade (HG) PPSC in a 70-year-old man with a history of prostatic adenocarcinoma. Core needle biopsy (CNB) touch preparation smears showed pleomorphic, round, columnar and polygonal epithelioid cells present singly or arranged in loosely cohesive three-dimensional clusters. The tumor cells are characterized by enlarged nuclei containing prominent nucleoli, and variable scant to moderate, slightly dense cytoplasm. Scattered cells contained cytoplasmic vacuoles. Examination of CNB revealed an infiltrating tumor in sheets with focal papillary configuration. Tumor cells were morphologically consistent with HG carcinoma. IHC studies demonstrated diffuse positivity for CK7, PAX-8, ER, WT1, p53, p16 and BerEP4 with focal/weak staining for calretinin and CK5/6, which supporting the diagnosis of HG PPSC. The patient was treated with 6 cycles of carboplatin and paclitaxel with near resolution of the mass at 10 month follow-up. To the best of our knowledge, this is the first reported case in the literature of PPSC in a man diagnosed by cytology. This article is protected by copyright. All rights reserved.

    Full Text Available Abstract Introduction The presence of oocytes in the ovarian surface epithelium has already been confirmed in the fetal ovaries. We report the presence of SSEA-4, SOX-2, VASA and ZP2-positive primitive oocyte-like cells in the adult ovarian surface epithelium of a patient with serous papillary adenocarcinoma. Case presentation Ovarian tissue was surgically retrieved from a 67-year old patient. Histological analysis revealed serous papillary adenocarcinoma. A proportion of ovarian cortex sections was deparaffinized and immunohistochemically stained for the expression of markers of pluripotency SSEA-4 and SOX-2 and oocyte-specific markers VASA and ZP2. The analysis confirmed the presence of round, SSEA-4, SOX-2, VASA and ZP2-positive primitive oocyte-like cells in the ovarian surface epithelium. These cells were possibly related to the necrotic malignant tissue. Conclusion Primitive oocyte-like cells present in the adult ovarian surface epithelium persisting probably from the fetal period of life or developed from putative stem cells are a pathological condition which is not observed in healthy adult ovaries, and might be related to serous papillary adenocarcinoma manifestation in the adult ovarian surface epithelium. This observation needs attention to be further investigated.

    1992-06-01

    A 62-year-old man with a 20-year history of chronic ulcerative colitis and a 9-year history of primary sclerosing cholangitis (PSC) underwent orthotopic liver transplantation because of symptoms related to PSC and cholangiographic features compatible with a biliary neoplasm. Study of the excised liver revealed papillary mucosal lesions in the common hepatic duct and the right and left hepatic ducts as well as cholangiectases and other features typically associated with PSC. The papillary lesions consisted of abundant fibrovascular stroma covered by biliary epithelium with low-grade and high-grade dysplasia. Some periductal glands were also dysplastic. These features distinguished papillary dysplasia from classic biliary papillomatosis. Only one focus of microinvasion was found; there were no metastases. Among 60 cases of PSC in whom the entire liver could be studied after orthotopic liver transplantation, this was the only instance of unequivocal dysplasia. However, in one specimen, papillary hyperplasia was found. Detailed macroscopic and microscopic rereview of 23 livers from our patients with the longest history of PSC (range, 5-24 years) failed to reveal any additional cases with dysplasia. It is concluded that (a) papillary mucosal lesions in PSC may represent papillary dysplasia without invasion; (b) these lesions may evolve from papillary hyperplasia; (c) the process may be largely, if not entirely, in situ; and (d) the prevalence of dysplasia and carcinoma of bile ducts may be less than the 7%-9% reported in the literature for malignancies associated with PSC.

    Conclusion: PFS was similar for advanced-stage PSPC and PSOC patients. Since the PSPC patients tended to be older and have more high-grade tumors, OS was shorter for PSPC than for POSC patients. Thus, management of the two types of cancer should not differ.

    Objectives: The optimal adjuvant therapy for International Federation of Gynecology and Obstetrics (FIGO) stage I papillary serous (UPSC) or clear cell (CC) endometrial cancer is unknown. We report on the largest single-institution experience using adjuvant high-dose-rate vaginal brachytherapy (VBT) for surgically staged women with FIGO stage I UPSC or CC endometrial cancer. Methods and Materials: From 1998-2011, 103 women with FIGO 2009 stage I UPSC (n=74), CC (n=21), or mixed UPSC/CC (n=8) endometrial cancer underwent total abdominal hysterectomy with bilateral salpingo-oophorectomy followed by adjuvant high-dose-rate VBT. Nearly all patients (n=98, 95%) also underwent extended lymph node dissection of pelvic and paraortic lymph nodes. All VBT was performed with a vaginal cylinder, treating to a dose of 2100 cGy in 3 fractions. Thirty-five patients (34%) also received adjuvant chemotherapy. Results: At a median follow-up time of 36 months (range, 1-146 months), 2 patients had experienced vaginal recurrence, and the 5-year Kaplan Meier estimate of vaginal recurrence was 3%. The rates of isolated pelvic recurrence, locoregional recurrence (vaginal + pelvic), and extrapelvic recurrence (including intraabdominal) were similarly low, with 5-year Kaplan-Meier estimates of 4%, 7%, and 10%, respectively. The estimated 5-year overall survival was 84%. On univariate analysis, delivery of chemotherapy did not affect recurrence or survival. Conclusions: VBT is effective at preventing vaginal relapse in women with surgical stage I UPSC or CC endometrial cancer. In this cohort of patients who underwent comprehensive surgical staging, the risk of isolated pelvic or extrapelvic relapse was low, implying that more extensive adjuvant radiation therapy is likely unnecessary.

  13. Inhibition of Hedgehog signaling antagonizes serous ovarian cancer growth in a primary xenograft model.

    Directory of Open Access Journals (Sweden)

    Christopher K McCann

    Full Text Available Recent evidence links aberrant activation of Hedgehog (Hh signaling with the pathogenesis of several cancers including medulloblastoma, basal cell, small cell lung, pancreatic, prostate and ovarian. This investigation was designed to determine if inhibition of this pathway could inhibit serous ovarian cancer growth.We utilized an in vivo pre-clinical model of serous ovarian cancer to characterize the anti-tumor activity of Hh pathway inhibitors cyclopamine and a clinically applicable derivative, IPI-926. Primary human serous ovarian tumor tissue was used to generate tumor xenografts in mice that were subsequently treated with cyclopamine or IPI-926.Both compounds demonstrated significant anti-tumor activity as single agents. When IPI-926 was used in combination with paclitaxel and carboplatinum (T/C, no synergistic effect was observed, though sustained treatment with IPI-926 after cessation of T/C continued to suppress tumor growth. Hh pathway activity was analyzed by RT-PCR to assess changes in Gli1 transcript levels. A single dose of IPI-926 inhibited mouse stromal Gli1 transcript levels at 24 hours with unchanged human intra-tumor Gli1 levels. Chronic IPI-926 therapy for 21 days, however, inhibited Hh signaling in both mouse stromal and human tumor cells. Expression data from the micro-dissected stroma in human serous ovarian tumors confirmed the presence of Gli1 transcript and a significant association between elevated Gli1 transcript levels and worsened survival.IPI-926 treatment inhibits serous tumor growth suggesting the Hh signaling pathway contributes to the pathogenesis of ovarian cancer and may hold promise as a novel therapeutic target, especially in the maintenance setting.

    Full Text Available The thyroglossal duct cysts (TGDCs are the most common congenital anomaly of the thyroid, usually manifested as painless midline neck mass. Malignancy is very rare and is reported in around 1% of cases as an incidental finding after histopathological evaluation of resected cyst. Papillary carcinoma is the most common carcinoma reported in TGDC. Here, we report a case of 17-year-old-female, who presented with a gradually increasing midline neck mass which moves with swallowing. On imaging a diagnosis of infected TGDC was made. The Sistrunk operation was done and a diagnosis of primary papillary carcinoma arising in a TGDC was rendered histopathologically. The contemporary appearance of papillary carcinoma thyroid was reported in about 20% cases of TGDC carcinoma, thus it is essential to differentiate primary papillary carcinoma arising in a TGDC from those of metastatic papillary carcinoma thyroid by strict diagnostic criteria.

    The aim of this paper was to investigate whether renal papillae of patients with nephrolithiasis are more radiodense than that of control patients and to evaluate the predictability of urolithiasis using papillary density differences between stone and non-stone formers. Renal papillary Hounsfield Unit (HU) measurements were conducted at the level of upper pole, middle region and lower pole of both kidneys in a total of 126 primary (group 1), 133 recurrent (group 2) stone disease patients and 108 controls (group 3). Mean patient age did not differ significantly between groups (P>0.05). Mean stone diameters (±SD) were 5.0±3.1 mm (3-9 mm) and 6.1±3.3 mm (3-15 mm) for primary and recurrent groups, respectively and group distributions and variances were similar (P>0.05). Mean papillary attenuation values (±SD) were 27.26±9.30 (4.00-56.00) in group 1, 30.42±9.88 (12.00-64.00) in group 2 and 25.83±2.72 (20.30-32.56) in the control group. The difference between the mean papillary attenuation value of the primary stone disease group and the control group was statistically insignificant (P=0.104). When the control group and the recurrent stone group was compared without variances, in terms of the mean renal papillary attenuation value, a statistical significance was achieved (P=0.000). With increasing renal papillary HU values, the risk of recurrent calcium stone disease is increased.

    1998-01-01

    Purpose: Uterine papillary serous carcinoma (UPSC) is a morphologically distinct variant of endometrial carcinoma that is associated with a poor prognosis, high recurrence rate, frequent clinical understaging, and poor response to salvage treatment. We retrospectively analyzed local control, actuarial overall survival (OS), actuarial disease-free survival (DFS), salvage rate, and complications for patients with Federation International of Gynecology and Obstetrics (FIGO) (1988) Stage I UPSC. Methods and Materials: This retrospective analysis describes 38 patients with FIGO Stage I UPSC who were treated with the combinations of radiation therapy, chemotherapy, total abdominal hysterectomy, and bilateral salpingo-oophorectomy (TAH/BSO), with or without a surgical staging procedure. Twenty of 38 patients were treated with a combination of low dose-rate (LDR) uterine/vaginal brachytherapy using 226 Ra or 137 Cs and conventional whole-abdomen radiation therapy (WART) or whole-pelvic radiation therapy (WPRT). Of 20 patients (10%) in this treatment group, 2 received cisplatin chemotherapy. Eighteen patients were treated with high dose-rate (HDR) vaginal apex brachytherapy using 192 Ir with an afterloading device and cisplatin, doxorubicin, and cyclophosphamide (CAP) chemotherapy (5 of 18 patients). Only 6 of 20 UPSC patients treated with combination LDR uterine/vaginal brachytherapy and conventional external beam radiotherapy underwent complete surgical staging, consisting of TAH/BSO, pelvic/para-aortic lymph node sampling, omentectomy, and peritoneal fluid analysis, compared to 15 of 18 patients treated with HDR vaginal apex brachytherapy. Results: The 5-year actuarial OS for patients with complete surgical staging and adjuvant radiation/chemotherapy treatment was 100% vs. 61% for patients without complete staging (p = 0.002). The 5-year actuarial OS for all Stage I UPSC patients treated with postoperative HDR vaginal apex brachytherapy and systemic chemotherapy was 94

Twenty-two cases in this study were...... with an ovarian tumor. PTH was found in 20 (91%) of the 22 cases in the Danish study. On the basis of this association of PTH with APSTs with implants and the close morphologic resemblance of PTH, not only to primary ovarian APSTs but also to noninvasive epithelial implants and endosalpingiosis, we speculate...... of ovarian and extraovarian low-grade serous proliferations (APST, noninvasive epithelial implants, and endosalpingiosis) that postulates that all of these lesions are derived from PTH, which appears to be induced by chronic inflammation. If this hypothesis is confirmed, it can be concluded that low...

    2003-01-01

    Full Text Available Serous cystadenomas are the most common cystic neoplasms of the pancreas. They may occur solely or coexist with other neoplasms. A 10 cm mass involving the body of the pancreas was observed in the computed tomography of a 61-year-old man with a previous history of bladder and prostate carcinoma. Ultrasonography and computed tomography of the mass demonstrated multiple small cysts associated with a central calcified scar. A distal pancreatectomy was performed. Pathological examination confirmed the diagnosis of serous microcystic adenoma. This is the first report of a serous cystadenoma of the pancreas with two metachronous neoplasms. This feature should be kept in mind during the diagnosis and evaluation of patients with serous cystadenoma.

    Full Text Available We are describing a 19-year-old white woman who presented with two synchronous primary cancers, namely glioblastoma multiforme and papillary thyroid cancer. The patient was admitted with dizziness, headache, and vomiting. CT head revealed acute intraparenchymal hematoma in the right cingulate gyrus and the splenium of the corpus callosum. Carotid and cerebral angiogram were unremarkable. MRI of the brain demonstrated a non-enhancing and non-hemorrhagic component of the lesion along the lateral margin of the hemorrhage just medial to the atrium of the right lateral ventricle that was suspicious for a tumor or metastasis. Brain biopsy confirmed it as glioblastoma mutiforme. CT chest was done to rule out primary cancer that revealed a 11 mm hypodense lesion in the left lobe of the thyroid and ultrasound-guided fine-needle aspiration biopsy confirmed it as papillary thyroid carcinoma. We should evaluate for multiple primary malignancies in young patients who are found to have primary index cancer.

    Cinamon, Udi

    2014-12-01

    Full Text Available Introduction Primary hyperparathyroidism (PHPT is associated with several cancer types, including papillary thyroid carcinoma (PTC. Objective To explore further the relation between PHPT and PTC. Methods By considering patients with PHPT as extra-suspicious for PTC, we studied an exemplar group of patients with PHPT with a small (≤1 cm thyroid nodule, which was negative in preoperative cytologic examination. During parathyroidectomy, a frozen section biopsy of the thyroid nodule confirmed PTC, as did the final surgical specimen, revealing that the preoperative cytology was false-negative. Additionally, relevant reports retrieved from the English literature addressing thyroid cancer and hyperparathyroidism were reviewed and processed. Results Four patients with PHPT were studied. Three had a multifocal thyroid disease, and three had neck lymph node metastasis. Processing previous report data supported an association between PHPT and PTC. Although thyroid nodularity among patients with PHPT was similar to the general population, PTC incidence was higher. This was true also for patients with secondary hyperparathyroidism. Conclusions This study emphasized that PHPT should be considered as a noteworthy risk factor for PTC. Fine needle aspiration of a thyroid nodule is the most valuable diagnostic procedure for thyroid cancer. Yet, false-negative results were reported in up to 10% of cases, especially in small, subcentimeter nodules. In line with our data and the literature, patients with PHPT should have both a detailed ultrasound addressing the thyroid and cytology of any thyroid nodule, including small subcentimeter lesions. Moreover, surgical flexibility, allowing intraoperative thyroid nodule sampling, should be considered even for “innocent” nodules.

    Amplification of c-erbB2 has been reported in over 30% of uterine serous carcinoma (USC) and found to confer poor survival because of high proliferation and increased resistance to therapy. In this study, we evaluated for the first time Trastuzumab emtansine (T-DM1), a novel antibody–drug conjugate, against multiple epidermal growth factor receptor-2 (HER2)-positive USC cells in vitro followed by developing a supportive in vivo model. Fifteen primary USC cell lines were assessed by immunohistochemistry (IHC) and flow cytometry for HER2 protein expression. C-erbB2 gene amplification was evaluated using fluorescent in situ hybridization. Sensitivity to T-DM1 and trastuzumab (T)-induced antibody-dependent cell-mediated cytotoxicity was evaluated in 5-h chromium release assays. T-DM1 and T cytostatic and apoptotic activities were evaluated using flow-cytometry-based proliferation assays. In vivo activity of T-DM1 versus T in USC xenografts in SCID mice was also evaluated. High levels of HER2 protein overexpression and HER2 gene amplification were detected in 33% of USC cell lines. T-DM1 was considerably more effective than trastuzumab in inhibiting cell proliferation and in causing apoptosis (P = 0.004) of USC showing HER2 overexpression. Importantly, T-DM1 was highly active at reducing tumor formation in vivo in USC xenografts overexpressing HER2 (P = 0.04) and mice treated with TDM-1 had significantly longer survival when compared to T-treated mice and control mice (P ≤ 0.0001). T-DM1 shows promising antitumor effect in HER2-positive USC cell lines and USC xenografts and its activity is significantly higher when compared to T. T-DM1 may represent a novel treatment option for HER2-positive USC patients with disease refractory to trastuzumab and traditional chemotherapy

    Full Text Available Serous macular detachment has only recently been recognized to occur in a significant number of eyes with macular pathology including diabetic retinopathy, retinal vein occlusion, Behçet disease, Irvine-Gass syndrome and pars planitis. These serous retinal detachments associated with retinal vascular leakage are not suspected clinically or angiographically but can be diagnosed with optical coherence tomography (OCT beneath the edematous neurosensory retina. The detection of shallow foveal detachment may be helpful in better understanding the pathogenesis of these disorders. In addition, the detection of serous macular detachment may also help to better guide and assess the results of therapy in the future. (Turk J Oph thal mol 2012; 42: 146-9

    Serous cystic neoplasms of pancreas are relatively rare tumours. Malignancy in these tumours is even more rare which is confirmed by metastasis to other organs or by perineural, vascular or surrounding soft tissue invasion. A 60 years old lady presented with vague upper abdominal pain. Computed tomography scan showed multiloculated cystic mass in the body of pancreas measuring 9 x 6 x 5 cm and not involving spleen. Pancreatectomy specimen showed a multicystic tumour having sponge-like appearance which showed vascular and soft tissue invasion of surrounding stroma on microscopic examination and was diagnosed as serous cystadenocarcinoma of pancreas.

    Full Text Available Serous cystadenoma is a common benign neoplasm that can be managed without surgery in asymptomatic patients provided that the diagnosis is certain. We describe a patient, whose pancreatic cyst exhibited a radiological appearance distinct from that of typical serous cystadenoma, resulting in diagnostic difficulties. CT and MRI showed a 10 cm-polycystic tumor with upstream dilatation of the main pancreatic duct (MPD, suggestive of intraductal papillary mucinous tumor (IPMT. Ultrasonographic aspect and EUS-guided fine-needle aspiration gave arguments for serous cystadenoma. ERCP showed a communication between cysts and the dilated MPD, compatible with IPMT. The patient underwent left pancreatectomy with splenectomy. Pathological examination concluded in a serous cystadenoma, with only a ductal obstruction causing proximal dilatation.

    Papillary carcinoma of the thyroid (PTC) constitutes a major proportion of all thyroid cancers and is generally believed to be a slow growing tumor with an indolent course. The diagnosis of PTC often makes the physician overly optimistic and complacent and yet this tumor can be aggressive in a subset of patients leading to death in a few months. The fundamental but subtle differences underlying the extremes in biologic behaviour of this complex and fascinating tumor remain poorly understood. Although there is a general agreement among the investigators regarding prognostic factors, controversy exists about the management of the disease. There is divided opinion with respect to the type and extent of surgery and the need for radioiodine (1 31 I) treatment in case of PTC. The experiences at Radiation Medicine Centre (RMC) of 1904 cases of differentiated thyroid carcinoma (DTC) registered during the period 1963-1990 are reviewed

    Ovarian carcinoma is the deadliest gynecological malignancy. Previous studies have suggested that the fallopian tube may be the primary site for high-grade serous carcinoma. In prophylactic salpingo-oophorectomies from women with hereditary high risk for ovarian cancer, precursors can be assessed prior to onset and studied as a model for serous cancer precursor lesions. Epidemiologic studies indicate that carcinogenesis may be a result of chronic fallopian tube injury. The aims of this study were to (1) to examine the incidence of serous tubal intraepithelial carcinoma (STIC) in relation to other clinical parameters and (2) to evaluate whether chronic fallopian tube injury was related to cancer development. This study enrolled 101 women, comprising the following three groups: hereditary (n = 60), sporadic serous cancer (n = 18; endometrial cancers were excluded), and control (n = 23). The cases were histologically examined and clinical risk factors were collected. The histological changes were compared between different patients and correlated to clinical risk factors. STICs were identified primarily on the fallopian tube fimbria. The incidence of STIC was 3 % in the hereditary patients. In sporadic serous cancer cases, 61 % were associated with STIC and tubal carcinoma (p STIC and invasive cancer were seen more often in the older patients than in the younger patients (p = 0.528). This small study, no correlation with chronic tubal injury or inflammation was identified.

    Peritoneum is a site for both primary and secondary tumors. Primary peritoneal tumors are fairly rare. The most common primary tumors of the peritoneum are malignant mesothelioma and serous papillary adenocarcinoma. Clear cell carcinoma of the peritoneum is extremely rare and often misdiagnosed as mesothelioma, serous carcinoma, or metastatic adenocarcinoma, so it represents a diagnostic challenge for both clinicians and pathologists. Up to date, to the best of our knowledge, only 11 cases of primary peritoneal clear cell carcinoma have been reported in the English literature. Distinguishing this tumor of the peritoneum versus ovarian carcinoma can be problematic. Herein, we report a rare case of primary peritoneal clear cell carcinoma occurring in a 49-year-old woman, along with a review of the literature. © The Author(s) 2015.

    Virtually all primary peritoneal carcinomas (PPCs) are of serous papillary type. We report an unusual histologic type of PPC composed of anaplastic giant cells, which exhibited an aggressive clinical course. A 72-year-old woman presented with lower abdominal pain. Computed tomography showed a diffuse omental thickening. The patient underwent an exploratory laparotomy with omentectomy, total hysterectomy, bilateral salpingo-oophorectomy, and appendectomy. Pathologic examination revealed extensive omental replacement by tumor but only superficial surface cortical involvement of both ovaries, a disease distribution consistent with a typical müllerian-derived PPC. However, this neoplasm was composed of diffuse anaplastic tumor giant cells, rather than serous carcinoma, which is the usual histologic type encountered in PPC. The patient died within 1 month after surgery. We report this unusual histologic variant of PPC to raise awareness that anaplastic giant cell carcinoma may arise in the pelvic peritoneum as a primary tumor.

    To describe a novel surgical technique for drainage of bullous serous and hemorrhagic choroidal detachments. A prospective, consecutive case series of 6 eyes with serous and/or hemorrhagic choroidal detachments secondary to intraocular surgery was documented to evaluate the feasibility of using the 25-gauge and 20-gauge transconjunctival trocar/cannula systems to drain choroidal detachments. Two eyes had expulsive hemorrhagic choroidal detachments and 4 eyes had serous choroidal detachments after glaucoma surgeries. A 25-gauge infusion line was placed in the anterior chamber. A 20-gauge (in eyes with hemorrhagic choroidal detachments) or a 25-gauge (in eyes with serous detachments) trocar/cannula system was inserted into the suprachoroidal space 7.0 mm from limbus. After drainage, the cannulas were removed and no sutures were placed. Pars plana vitrectomy was performed only in eyes with concomitant pathology that demanded the additional procedure. The primary outcome measure was presence of choroidal detachment at 1 week, 2 weeks, and 1 month postoperatively. Secondary outcome measures were visual acuity at 6 months and intraocular pressure at 1 week and 1, 3, and 6 months postoperatively. Drainage of hemorrhagic choroidal detachments resulted in resolution of the detachments by 1 month postoperatively. In eyes with serous detachments, resolution was achieved by 1 week postdrainage. In both groups, intraocular pressure increased to at least 10 mmHg by postoperative Week 1. The visual acuity improved in all eyes. No complications related to the transconjunctival technique were noted. Transconjunctival drainage of serous and hemorrhagic choroidal detachments seems to be a feasible and simple surgical option with minimal scleral and conjunctival damage. Pars plana vitrectomy may not be necessary when draining choroidal detachments in this manner.

    2017-05-01

    In recent years it has become clear that many extra-uterine (pelvic) high-grade serous carcinomas (serous carcinomas) are preceded by a precursor lesion in the distal fallopian tube. Precursors range from small self-limited 'p53 signatures' to expansile serous tubal intraepithelial neoplasms that include both serous tubal epithelial proliferations (or lesions) of uncertain significance and serous tubal intraepithelial carcinomas. These precursors can be considered from three perspectives. The first is biologic underpinnings, which are multifactorial, and include the intersection of DNA damage with Tp53 mutations and disturbances in transcriptional regulation that increase with age. The second perspective is the morphologic discovery and classification of intraepithelial neoplasms that are intercepted early in their natural history, either incidentally or in risk-reduction surgeries for germline mutations. For the practicing pathologist, as well as the investigators, a distinction between a primary intraepithelial neoplasm and an intramucosal carcinoma must be made to avoid misinterpreting (or underestimating) the significance of these proliferations. The third perspective is the application of this information to intervention, devising strategies that will actually lower the ovarian cancer death rate by opportunistic salpingectomy, widespread comprehensive genetic screening and early detection. Central to this issue are the questions of (1) whether some STICs are metastatic, (2) whether lower-grade epithelial proliferations can invade prior to evolving into intraepithelial carcinoma, or (3) metastasize and become malignant elsewhere ('precursor escape'). An important caveat is the persistent and unsettling reality that many high-grade serous carcinomas are not associated with an obvious point of initiation in the fallopian tube. The pathologist sits squarely in the midst of all of these issues, and has a pivotal role in managing expectations for stemming the death

    Synchronous primary cancers of the endometrium and ovary are found in 5% of women with endometrial cancer and 10% of women with ovarian cancer. In the present case, a multigravid 46-year-old woman complained of lower abdominal pain and abdominal distension. She did not define abnormal uterine bleeding. Screening ultrasound revealed a papillary containing structure, irregular, cystic 16 x 15 x 10 cm right ovarian mass. Preoperative endometrial biopsy revealed endometrioid adenocarcinoma. Ascites sampling, radical hysterectomy, bilateral salpingo-oophorectomy, pelvic and paraaortic lymphadenectomy, omentectomy, appendectomy and cytologic sampling of the undersurface of the diaphragm were carried out. Intraoperative and histological examinations showed Stage IIIC papillary serous carcinoma and stage IC endometrioid adenocarcinoma. Synchronous genital tract neoplasms constitute a more common clinical problem than would generally be expected.

    Full Text Available Serous cystadenomas are rare tumors comprising 1-2% of exocrine pancreas tumors. They are mostly known as benign conditions but malign transformation as serous cystadenocarcinoma is also reported. It is usually seen in females. Non-specific symptoms, such as abdominal pain or symptoms due to mass affect, are usually seen. A 64-year old female patient was investigated for abdominal pain. Physical and laboratory findings were normal. Abdomen ultrasonography confirmed an 11x9.5 cm solid cystic lesion and abdomen computed tomography scan confirmed a 12x11 cm lobulated cystic solid lesion which had central cystic necrotic areas extending from liver hilus inferiorly. Fine needle biopsy confirmed benign cytology and trucut biopsy of the pan creatic mass reported chronic inflamation. Nevertheless, this mass could have malignant contents and transformation potential. A laparatomy was decided due to patient’s symptoms and mass effect. Due to vascular invasion of the tumor, Whipple procedure was performed. The pathology report confirmed serous microcystic adenoma. These rare tumors are usually benign but pre-operative malignity criterias are not identified. There are few differential diagnostic tools for excluding malignity. We suggest surgical resection as best treatment approach for selected cases.

    Recent data suggest that intraepithelial carcinoma of the fallopian tube [serous tubal intraepithelial carcinoma (STIC)] is the precursor of high-grade extrauterine serous carcinoma. A more specific location for the origin of this lesion is suggested by the recently described junction between the fallopian tubal epithelium and the peritoneum [tubal-peritoneal junction (TPJ)]. Fallopian tubes from 202 patients with advanced-stage high-grade extrauterine serous carcinoma or carcinosarcoma were evaluated histologically as were 124 prophylactic salpingo-oophorectomy specimens. These included 54 patients with BRCA or other high-risk mutation or a family history of BRCA mutation and 70 with a personal or family history of breast carcinoma. STIC was found in 81 of 202 patients with serous carcinoma (40.1%). STIC was present in 73 of 141 (52%) cases in which the fimbriae were present and in 62 of 100 (62%) cases in which the TPJ was present (P not significant). In comparison with these groups, when fimbriae and TPJ were absent, STIC was found in 8 of 61 (13%) cases (PSTIC. The mean size of STIC was 1.7 mm. In 32 cases (39.5%), the lesion was flat and in 49 (60.5%), papillary. The mean size of flat STICs was 0.8 mm as compared with 2.3 mm for papillary STICs (P=0.00005). STIC was identified in the same tissue fragment as the junction in 48 cases. The mean distance of STIC to the junction was 1.8 mm. In 11 cases, STIC was flanked by peritoneal mesothelium on one side and tubal epithelium on the opposite side. In 51 patients, the mean distance of invasive carcinoma from the TPJ was 1.8 mm. This distance was 1.9 mm when STIC was present (37 cases) in comparison with 1.5 mm when STIC was absent (14 cases) (P not significant). In 27 of 42 cases (64%), STIC was contiguous with invasive carcinoma. Lamina propria invasion was present in 71% of cases in which STIC was present as compared with 26% of cases in which STIC was absent (PSTIC was present as compared with 26% of cases in

    It has been proposed that the presence of tubal intraepithelial carcinoma (TIC), in association with one-third to nearly half of pelvic serous carcinomas, is evidence of fallopian tube origin for high-grade serous carcinomas that would have been otherwise classified as primary ovarian or peritoneal. To address this hypothesis, we evaluated a series of 114 consecutive pelvic (nonuterine) gynecologic carcinomas at our institution (2006 to 2008) to determine the frequency of TIC in 52 cases in which all the resected fallopian tube tissue was examined microscopically. These 52 cases were classified as ovarian (n=37), peritoneal (n=8), or fallopian tube (n=7) in origin as per conventional criteria based on disease distribution. The presence of TIC and its location and relationship to invasive carcinoma in the fallopian tubes and ovaries were assessed. Among the 45 cases of ovarian/peritoneal origin, carcinoma subtypes included 41 high-grade serous, 1 endometrioid, 1 mucinous, 1 high-grade, not otherwise specified, and 1 malignant mesodermal mixed tumor. TIC was identified in 24 cases (59%) of high-grade serous carcinoma but not among any of the other subtypes; therefore, the term serous TIC (STIC) is a more specific appellation. STICs were located in the fimbriated end of the tube in 22 cases (92%) and in the ampulla in 2 (8%); they were unilateral in 21 (88%) and bilateral in 3 (13%). STICs in the absence of an associated invasive carcinoma in the same tube were detected in 7 cases (30%) and with invasive carcinoma in the same tube in 17 (71%). Unilateral STICs were associated with bilateral ovarian involvement in 15 cases and unilateral (ipsilateral) ovarian involvement in 5 (the remaining case with a unilateral STIC had a primary peritoneal tumor with no ovarian involvement); the bilateral STICs were all associated with bilateral ovarian involvement. Six of the 7 primary tubal tumors were high-grade serous carcinomas, and 4 of these 6 (67%) had STICs. Based on

    Papillary endothelial hyperplasia (Masson's tumour) is a reactive proliferation of endothelium producing papillary structures with fibrovascular cores. Dilatation, stasis and accompanying inflammation have been incriminated as the inciting events, evident by the presence of this lesion in haemorrhoids, urethral caruncles and laryngeal polyps. We present here a case of papillary endothelial hyperplasia in angiokeratoma hitherto undescribed despite sharing common etiopathogenetic features of dilatation and stasis with other aforementioned lesions.

  5. Oxidatively Modified Proteins in the Serous Subtype of Ovarian Carcinoma

    Full Text Available Serous subtype of ovarian cancer is considered to originate from fallopian epithelium mucosa that has been exposed to physiological changes resulting from ovulation. Ovulation influences an increased in inflammation of epithelial ovarian cells as results of constant exposure of cells to ROS. The imbalance between ROS and antioxidant capacities, as well as a disruption of redox signaling, causes a wide range of damage to DNA, proteins, and lipids. This study applied spectrophotometric, dinitrophenylhydrazone (DNPH assay, two-dimensional gel electrophoresis, and Western blot analyses to assess the levels of oxidatively modified proteins in 100 primary serous epithelial ovarian carcinoma and normal/surrounding tissues. These samples were obtained from 56 Caucasian and 44 African-American patients within the age range of 61±10 years. Analyses showed that the levels of reactive protein carbonyl groups increased as stages progressed to malignancy. Additionally, the levels of protein carbonyls in serous ovarian carcinoma among African Americans are 40% (P<0.05 higher relative to Caucasian at similar advanced stages. Results suggest that oxidative stress is involved in the modification of carbonyl protein groups, leading to increased aggressiveness of epithelial ovarian tumors and may contribute to the disease's invasiveness among African Americans.

    To evaluate the safety and efficacy of ultrasound-guided low-power microwave ablation (MWA) for the treatment of papillary thyroid microcarcinoma (PTMC) with a 3-year follow-up. A total of 21 nodules diagnosed as PTMC from the 15 patients were performed with MWA at a power of 20 W. The images of the nodules were recorded by ultrasound before MWA and 1, 3, 6, 12 months after MWA, and every 6 months thereafter, respectively. The volumes of the nodules were compared before MWA and at each follow-up point after MWA. The volume reduction rate (VRR) of nodules was also calculated. The mean volume of the nodules was 134.3 ± 129.8 mm 3 initially (the range was 7.4-423.8 mm 3 ), which decreased significantly to 2.3 ± 10.5 mm 3 (the range was 0-48.1 mm 3 ) of the ablation area (P = 0.000) at the follow-up point of 36 months with a mean VRR as 98.78 ± 5.61% (the range was 74.28-100%). During the follow-up period (the range was 36-48 months), 20 of the 21 nodules were completely absorbed and no recurrent nodule was found. After a long-term follow-up of 3 years, the low power MWA showed a good safety and efficacy for the treatment of PTMC. In addition to surgery and active surveillance, MWA might be another alternative for patients with PTMC.

    To quantify retinal fluorescence lifetimes in patients with central serous chorioretinopathy (CSC) and to identify disease specific lifetime characteristics over the course of disease. Forty-seven participants were included in this study. Patients with central serous chorioretinopathy were imaged with fundus photography, fundus autofluorescence, optical coherence tomography, and fluorescence lifetime imaging ophthalmoscopy (FLIO) and compared with age-matched controls. Retinal autofluorescence was excited using a 473-nm blue laser light and emitted fluorescence light was detected in 2 distinct wavelengths channels (498-560 nm and 560-720 nm). Clinical features, mean retinal autofluorescence lifetimes, autofluorescence intensity, and corresponding optical coherence tomography (OCT) images were further analyzed. Thirty-five central serous chorioretinopathy patients with a mean visual acuity of 78 ETDRS letters (range, 50-90; mean Snellen equivalent: 20/32) and 12 age-matched controls were included. In the acute stage of central serous chorioretinopathy, retinal fluorescence lifetimes were shortened by 15% and 17% in the respective wavelength channels. Multiple linear regression analysis showed that fluorescence lifetimes were significantly influenced by the disease duration (P autofluorescence lifetimes, particularly in eyes with retinal pigment epithelial atrophy, were associated with poor visual acuity. This study establishes that autofluorescence lifetime changes occurring in central serous chorioretinopathy exhibit explicit patterns which can be used to estimate perturbations of the outer retinal layers with a high degree of statistical significance.

    Papillary renal-cell carcinoma, which accounts for 15 to 20% of renal-cell carcinomas, is a heterogeneous disease that consists of various types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal-cell carcinoma, and no effective forms of therapy for advanced disease exist. We performed comprehensive molecular characterization of 161 primary papillary renal-cell carcinomas, using whole-exome sequencing, copy-number analysis, messenger RNA and microRNA sequencing, DNA-methylation analysis, and proteomic analysis. Type 1 and type 2 papillary renal-cell carcinomas were shown to be different types of renal cancer characterized by specific genetic alterations, with type 2 further classified into three individual subgroups on the basis of molecular differences associated with patient survival. Type 1 tumors were associated with MET alterations, whereas type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-antioxidant response element (ARE) pathway. A CpG island methylator phenotype (CIMP) was observed in a distinct subgroup of type 2 papillary renal-cell carcinomas that was characterized by poor survival and mutation of the gene encoding fumarate hydratase (FH). Type 1 and type 2 papillary renal-cell carcinomas were shown to be clinically and biologically distinct. Alterations in the MET pathway were associated with type 1, and activation of the NRF2-ARE pathway was associated with type 2; CDKN2A loss and CIMP in type 2 conveyed a poor prognosis. Furthermore, type 2 papillary renal-cell carcinoma consisted of at least three subtypes based on molecular and phenotypic features. (Funded by the National Institutes of Health.).

    Background Papillary renal cell carcinoma, accounting for 15% of renal cell carcinoma, is a heterogeneous disease consisting of different types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal cell carcinoma; no effective forms of therapy for advanced disease exist. Methods We performed comprehensive molecular characterization utilizing whole-exome sequencing, copy number, mRNA, microRNA, methylation and proteomic analyses of 161 primary papillary renal cell carcinomas. Results Type 1 and Type 2 papillary renal cell carcinomas were found to be different types of renal cancer characterized by specific genetic alterations, with Type 2 further classified into three individual subgroups based on molecular differences that influenced patient survival. MET alterations were associated with Type 1 tumors, whereas Type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-ARE pathway. A CpG island methylator phenotype (CIMP) was found in a distinct subset of Type 2 papillary renal cell carcinoma characterized by poor survival and mutation of the fumarate hydratase (FH) gene. Conclusions Type 1 and Type 2 papillary renal cell carcinomas are clinically and biologically distinct. Alterations in the MET pathway are associated with Type 1 and activation of the NRF2-ARE pathway with Type 2; CDKN2A loss and CIMP in Type 2 convey a poor prognosis. Furthermore, Type 2 papillary renal cell carcinoma consists of at least 3 subtypes based upon molecular and phenotypic features. PMID:26536169

    In recent years it has become clear that many extra-uterine (pelvic) high-grade serous carcinomas (serous carcinomas) are preceded by a precursor lesion in the distal fallopian tube. Precursors range from small self-limited 'p53 signatures' to expansile serous tubal intraepithelial neoplasms that

    Typical papillary hyperplasia, a recently recognized precursor lesion to low-grade papillary urothelial neoplasms, consists of undulating folds of cytologically benign urothelium. Well-developed, branching fibrovascular cores of a papillary neoplasm are not evident. We have noted lesions with the architectural pattern of papillary hyperplasia; however, the overlying urothelium demonstrated varying degrees of cytologic atypia. We identified 15 cases of atypical papillary hyperplasia (13 males, 2 females, age 55 to 92) with overlying urothelium showing cytologic atypia. Of these cases, 8 (53%) were received in consultation. Of the 15 cases, 8 exhibited overlying flat carcinoma in situ (CIS), 4 had overlying dysplasia, and 3 were transitional between papillary hyperplasia with atypia and the earliest lesions of papillary neoplasia. Of these cases, 5 patients had multiple specimens with atypical papillary hyperplasia (range, 2 to 8) over time. Concurrent to the diagnosis of atypical papillary hyperplasia, there were 25 different urothelial lesions: CIS (n = 11), papilloma (n = 1), papillary neoplasm of low malignant potential with CIS (n = 1), high-grade papillary urothelial carcinoma (n = 10; 3 with CIS), small-cell carcinoma (n = 1), and infiltrating urothelial carcinoma (n = 1). Of 11 patients with known prior history, 2 had 12 prior urothelial neoplasms (9 low-grade papillary neoplasms, 2 papillary urothelial neoplasms of low malignant potential, and 1 high-grade papillary cancer). Of 10 patients with atypical papillary hyperplasia and a minimum of 1 year of follow-up, 9 had 19 recurrences: CIS (n = 4), papilloma (n = 1), papillary neoplasm of low malignant potential (n = 1), infiltrating urothelial carcinoma (n = 3; 1 with CIS), and high-grade papillary urothelial carcinoma (n = 10; 5 with invasion and 2 with CIS). Whether the papillary hyperplasia had overlying CIS or dysplasia did not affect the correlation with urothelial neoplasms. Immunohistochemical analysis

    Median ectopic thyroid may be encountered anywhere from the foramen caecum to the diaphragm. Non lingual median aberrant thyroid (incomplete descent) usually found in the infrahyoid region and malignant transformation in this ectopic thyroid tissue is very rare. We report an extremely rare case of papillary carcinoma in non lingual median aberrant thyroid in a 25-year-old female. The differentiation between a carcinoma arising in the median ectopic thyroid tissue and a metastatic papillary carcinoma from an occult primary in the main thyroid gland is also discussed.

    Full Text Available Abstract Both intraparenchymal papillary meningioma and papillary meningioma with cyst formation of brainstem have never been reported. The authors present an extremely rare case of patient with intraparenchymal papillary meningioma of brainstem. A 23-year-old Chinese male presented with a 4-month history of progressive left upper limb and facial nerve palsy. Magnetic resonance imaging revealed a cystic-solid, heterogeneously enhancing mass in pons and right cerebral peduncle with no dural attachment. The tumor was totally removed via subtemporal approach. During surgery, the lesion was found to be completely intraparenchymal. Histological and immunohistochemical examinations were compatible with the diagnosis of papillary meningioma. The lesion recurred nine months after primary surgery, a second surgery followed by radiotherapy was performed. Till to now (nearly 2 years after the treatment, the patient is tumor free survival. Intraparenchymal meningioma of brainstem with cystic formation is very rare, however, it should be considered as a differential diagnosis of a brainstem neoplasm. The present case strongly recommended that postoperative radiotherapy was essential for the patients with papillary meningiomas.

    Full Text Available Thyroid carcinoma is rare comprising 1% of all malignancies and commonly presents as a neck lump. Papillary thyroid carcinoma unlike follicular thyroid carcinoma tends not to metastasise to distant sites.We present a case of papillary thyroid carcinoma presenting as a solitary asymptomatic pelvic bone metastases and highlight current management of bone metastases. A 59-year old female was found on abdominal computerised tomography to have an incidental finding of a 4.5 cm soft tissue mass in the right iliac bone. Biopsy of the lesion confirmed metastatic thyroid carcinoma. There was no history of a neck lump, head and neck examination was normal. Further imaging confirmed focal activity in the right lobe of the thyroid. A total thyroidectomy and level VI neck dissection was performed and histology confirmed follicular variant of papillary carcinoma.Early detection of bone metastases have been shown to improve prognosis and thyroid carcinoma should be considered as a potential primary malignancy.

    Minimal uterine serous cancer (MUSC) or serous endometrial intraepithelial carcinoma (EIC) has been described by many different names since 1998. There have been very few cases reported in literature since EIC/MUSC was recognized as a separate entity. The World health Organization (WHO) Classification favors the term serous EIC. Although serous EIC is confined to the uterine endometrium at initial histology diagnosis, a significant number of patients could have distal metastasis at diagnosis, without symptoms. Serous EIC is considered as being the precursor of uterine serous cancer (USC), but pure serous EIC also has an aggressive behavior similar to USC. It is therefore prudent to have an accurate diagnosis and appropriate surgical staging. There are very few published articles in literature that discuss the pure form of serous EIC. The aim of this series is to share our experience and review evidence for optimum management of serous EIC. We report a series of five women treated in our institute in the last 3 years. We reviewed the relevant literature on serous EIC and various management strategies, to recommend best clinical practice. Pure serous EIC is a difficult histopathological diagnosis, which requires ancillary immunohistochemical staining. It can have an aggressive clinical behavior with early recurrence and poor survival. Optimum surgical staging, with appropriate adjuvant treatment, should be discussed when treating these patients

    To evaluate the safety and efficacy of finasteride, an inhibitor of dihydrotestosterone synthesis, in the treatment of chronic central serous chorioretinopathy. Five patients with chronic central serous chorioretinopathy were prospectively enrolled in this pilot study. Patients were administered finasteride (5 mg) daily for 3 months, after which study medication was withheld and patients were observed for 3 months. Main outcome measures included best-corrected visual acuity, central subfield macular thickness, and subretinal fluid volume as assessed by optical coherence tomography. Serum dihydrotestosterone, serum testosterone, and urinary cortisol were also measured. There was no change in mean best-corrected visual acuity. Mean center-subfield macular thickness and subretinal fluid volume reached a nadir at 3 months and rose to levels that were below baseline by 6 months. The changes in both optical coherence tomography parameters paralleled those in serum dihydrotestosterone level. In four patients, center-subfield macular thickness and/or subretinal fluid volume increased after discontinuation of finasteride. In the remaining patient, both optical coherence tomography parameters normalized with finasteride and remained stable when the study medication was discontinued. Finasteride may represent a novel medical treatment for chronic central serous chorioretinopathy. Larger controlled clinical trials are needed to further assess the efficacy of finasteride for the treatment of central serous chorioretinopathy.

  20. Mucosal Proliferations in Completely Examined Fallopian Tubes Accompanying Ovarian Low-grade Serous Tumors: Neoplastic Precursor Lesions or Normal Variants of Benign Mucosa?

    Malignant transformation of the fallopian tube mucosa, followed by exfoliation of malignant cells onto ovarian and/or peritoneal surfaces, has been implicated as the origin of most pelvic high-grade serous carcinoma. Whether a parallel pathway exists for pelvic low-grade serous tumors [ovarian serous borderline tumor (SBT) and low-grade serous carcinoma (LGSC)] remains to be fully elucidated. The literature is challenging to interpret due to variation in the diagnostic criteria and terminology for cytologically low-grade proliferations of the fallopian tube mucosa, as well as variation in fallopian tube specimen sampling. Recently, a candidate fallopian tube precursor to ovarian SBT, so-called papillary tubal hyperplasia, was described in advanced stage patients. The current study was designed to identify fallopian tube mucosal proliferations unique to patients with low-grade serous ovarian tumors (serous cystadenoma, SBT, LGSC) and to determine if they may represent precursors to the ovarian tumors. Fallopian tubes were thinly sliced and entirely examined microscopically, including all of the fimbriated and nonfimbriated portions of the tubes, from patients with ovarian serous cystadenoma (35), SBT (61), and LGSC (11) and from a control population of patients with ovarian mucinous cystadenoma (28), mature cystic teratoma (18) or uterine leiomyoma (14). The slides of the fallopian tubes were examined in randomized order, without knowledge of the clinical history or findings in the ovaries or other organs. Alterations of the mucosa of the fallopian tube were classified as type 1: nonpapillary proliferation of cytologically bland tubal epithelium exhibiting crowding, stratification, and/or tufting without papillary fibrovascular cores or as type 2: papillary alterations consisting of a fibrovascular core lined by a cytologically bland layer of tubal epithelium. A third abnormality, type 3, consisted of detached intraluminal papillae, buds, or nests of epithelium that

    The case of a 30-year-old man with papillary cystadenoma of the epididymis is presented. This extremely rare lesion is often associated with von Hippel-Lindau disease, although in this case there were no such signs or symptoms. The gross and microscopic features of this lesion and theories of its origin are reviewed. The constant microscopic features are: efferent duct ectasia with papillary formation, a lining of cuboidal epithelium, often with clear vacuolated cytoplasm, and a stroma of hyalinized fibrous tissue infiltrated by inflammatory cells.

    The topical issues is the problem of prognosis of metastasis radioiodine resistant metastasis. We offered the methods of prognosis of metastasis radioiodine resistant of papillary thyroid carcinoma with the help of immunocytochemical detection of the cytokeratin 17 and thyroid peroxidase. With the purpose of prognosis of metastasis radioiodine resistibility the cytokeratin 17 is taped in punctates of primary papillary carcinomas. This approach allows predict response of metastases on radioiodine therapy to choose proper therapeutic approach

    Full Text Available Background. Simultaneous presence of Hashimoto's thyroiditis and papillary thyroidal carcinoma in thyroidal gland with papillary carcinoma association in thyroglossal duct is quite rare. The questions like where the original site of primary process, is where metastasis is, what the cause of coexisting of these diseasesis present a diagnostic dilemma. Case report. We presented a case of a 53-year old female patient, with the diagnosis of Hashimoto's thyroiditis and symptoms of subclinical hypothyreosis and nodal changes in the right lobe of thyroidal gland, according to clinical investigation. Morphological examination of thyroidal gland, ultrasound examination and scintigraphy with technetium (Tc confirmed the existence of nonhomogenic tissue with parenchyma nodular changes in the right lobe of thyroidal gland that weakly bonded Tc. Fine needle biopsy in nodal changes, with cytological analyses showed no evidence of atypical thyreocites. Hashimoto's thyroiditis was confirmed on the basis of the increased values of anti-microsomal antibodies, the high levels of thyreogobulin 117 ng/ml and TSH 6.29 μIU/ml. The operation near by the nodular change in the right lobe of thyroidal gland revealed pyramidal lobe spread in the thyroglossal duct. Total thyroidectomia was done with the elimination of thyroglossal duct. Final patohystological findings showed papillary carcinoma in the nodal changes pT2, N0 and in the thyroglossal duct with the presence of Hashimoto's thyroiditis in the residual parenchyme of the thyroid gland. After the surgery the whole body scintigraphy with iodine 131 (131I did not reveal accumulation of 131I in the body, while the fixation in the neck was 1%. After that, the patient was treated with thyroxin with suppressionsubstitution doses. Conclusion. Abnormality in embrional development of thyroidal tissue might be the source of thyroidal carcinoma or the way of spreading of metastasis of primary thyroidal carcinoma from thyroid

    Ovarian serous borderline tumors (SBTs) have been the subject of considerable controversy, particularly with regard to terminology and behavior. It has been proposed that they constitute a heterogenous group of tumors composed, for the most part, of typical SBTs that are benign and designated...... "atypical proliferative serous tumor (APST)" and a small subset of SBTs with micropapillary architecture that have a poor outcome and are designated "noninvasive low-grade serous carcinoma (niLGSC)". It also has been argued that the difference in behavior between the 2 groups is not due to the subtype...... of the primary tumor but rather the presence of extraovarian disease, specifically invasive implants. According to the terminology of the 2014 WHO Classification, typical SBTs are equivalent to APSTs and SBTs displaying micropapillary architecture are synonymous with niLGSC. In addition, "invasive implants" were...

    Serous tubal intraepithelial carcinoma (STIC) is detected in between 5% and 7% of women undergoing risk-reduction salpingooophorectomy for mutations in the BRCA1 or 2 genes (BRCA+), and seems to play a role in the pathogenesis of many ovarian and "primary peritoneal" serous carcinomas. The recognition of STIC is germane to the management of BRCA+ women; however, the diagnostic reproducibility of STIC is unknown. Twenty-one cases were selected and classified as STIC or benign, using both hematoxylin and eosin and immunohistochemical stains for p53 and MIB-1. Digital images of 30 hematoxylin and eosin-stained STICs (n=14) or benign tubal epithelium (n=16) were photographed and randomized for blind digital review in a Powerpoint format by 6 experienced gynecologic pathologists and 6 pathology trainees. A generalized kappa statistic for multiple raters was calculated for all groups. For all reviewers, the kappa was 0.333, indicating poor reproducibility; kappa was 0.453 for the experienced gynecologic pathologists (fair-to-good reproducibility), and kappa=0.253 for the pathology residents (poor reproducibility). In the experienced group, 3 of 14 STICs were diagnosed by all 6 reviewers, and 9 of 14 by a majority of the reviewers. These results show that interobserver concordance in the recognition of STIC in high-quality digital images is at best fair-to-good for even experienced gynecologic pathologists, and a proportion cannot be consistently identified even among experienced observers. In view of these findings, a diagnosis of STIC should be corroborated by a second pathologist, if feasible.

    Pancreatic heterotopias (HP) are rare. They can occur at any age with a slight male predominance. These lesions are usually asymptomatic and they are often found incidentally during upper or lower GI endoscopy or during the anatomo-pathological examination of an organ which was resected for other reasons; they can be isolated or associated with a digestive pathology. We report, through observation, the association of HP with serous cystadenoma of the pancreas discovered during examinations to identify the etiology of isolated abdominal pain. The aim of this study is to analyse clinical and histological features of this rare pathology.

    In most cases, the histopathologic and cytologic distinction between Graves' disease and papillary thyroid carcinoma is relatively easy, but on occasion Graves' disease may simulate a thyroid papillary carcinoma. For example, papillary fronds with fibrovascular cores may be present in both Graves' disease and papillary carcinoma. p27kip1 (p27) is a cyclin-dependent kinase inhibitory protein that has been shown to be an independent prognostic factor in a variety of human tumors. Our previous studies of p27 expression in hyperplastic and neoplastic endocrine lesions showed that the level of p27 was quite different in these two conditions. To determine if this distinction could also be made between Graves' disease and papillary carcinoma, we analyzed expression of p27 and other cell cycle proteins in a series of cases of Graves' disease with papillary hyperplasia and a series of papillary thyroid carcinomas. Formalin-fixed paraffin-embedded tissues from 61 randomly selected patients with thyroid disease, including 29 cases of Graves' disease with papillary architectural features and 32 cases of papillary carcinoma, were analyzed for expression of p27, Ki-67, and DNA topoisomerase II alpha (topo II alpha) by immunostaining. The distribution of immunoreactivity was analyzed by quantifying the percentage of positive nuclei that was expressed as the labeling index (LI) plus or minus the standard error of the mean. The papillary hyperplasia of Graves' disease had a p27 LI of 68.2 +/- 3.1 (range, 24 to 88), whereas papillary carcinomas had a LI of 25.6 +/- 2.5 (range, 12 to 70) (P hyperplasia in Graves' disease and papillary carcinoma. These results indicate that p27 protein expression is significantly higher in papillary hyperplasia of Graves' disease compared to papillary carcinoma, which may be diagnostically useful in difficult cases.

    Gynecologic and primary peritoneal serous carcinoma may be difficult to distinguish from abdominal mesotheliomas clinically, morphologically, and immunohistochemically. BAP1 double-hit inactivation and subsequent loss of protein expression have been reported in more than half of all abdominal mesotheliomas. We therefore sought to investigate the expression of BAP1 in serous carcinoma and explore its potential utility as a marker in the differential diagnosis with mesothelioma. We searched the computerized database of the Department of Anatomical Pathology, Royal North Shore Hospital, Australia, for all cases of gynecologic and peritoneal serous carcinomas and mesotheliomas diagnosed between 1998 and 2014. Immunohistochemistry for BAP1 was then performed on tissue microarray sections. Cases with completely absent nuclear staining in the presence of a positive internal control in nonneoplastic cells were considered negative. If staining was equivocal (eg, absent nuclear staining but no internal control), staining was repeated on whole sections. Loss of BAP1 expression was found in only 1 of 395 (0.3%) serous carcinomas but in 6 of 9 (67%) abdominal mesotheliomas (P < .001) and 131 of 277 (47%) thoracic mesotheliomas (P < .001). We conclude that BAP1 loss occurs extremely infrequently in gynecologic and peritoneal serous adenocarcinomas, whereas it is very common in mesotheliomas including abdominal mesothelioma. Therefore, although positive staining for BAP1 cannot be used to exclude a diagnosis of mesothelioma, loss of BAP1 expression can be used to very strongly support a pathological diagnosis of abdominal mesothelioma over serous carcinoma.

    Borderline ovarian tumors (BOT) arise from cystadenomas and represent a transition step within the development of low-grade ovarian carcinomas (Type I tumors). That pathway mirrors the adenoma-to-carcinoma sequence known for colorectal cancer. It has been suggested that papillary tubal hyperplasia (PTH) and salpingoliths may be associated with the development of BOT. To evaluate the frequency of the presence of benign cystadenoma and its transition to BOT in a given patient as well as the presence of PTH and salpingoliths we re-valuated in 74 consecutive cases of BOT with different histologic types. The majority of cases represented serous-BOT (60.8%), followed by mucinous BOT (25.7%), other histologic types were rare. 86.5% showed an adenoma-BOT sequence, which was seen in all mucinous BOT but was missed in 15.6% of serous BOT. Two cases had salpingoliths without associated PTH. PTH was seen in four out of the 74 (5.4%) BOT and occurred only in cases with serous histology. The vast majority of BOT represent a transition from benign cystadenoma to BOT in cases with mucinous and serous histology. Salpingoliths are rarely seen in association with BOT and occurred exclusively in BOT with serous histology. PTH may represent a distinct lesion but is rarely seen in association with BOT, especially in those with non-serous histology. Further studies are needed to evaluate the frequency and pathogenetic association of PTH with BOT. Copyright © 2017 Elsevier GmbH. All rights reserved.

    Serous ovarian neoplasms can overlap morphologically with peritoneal mesothelial proliferations, including well-differentiated papillary mesothelioma (WDPM) and malignant epithelioid mesothelioma (MM). Accurate histologic classification of these neoplasms is important for clinical management. The Pax-8 protein is commonly used for differentiating peritoneal MM from serous carcinoma, but the diagnostic value of Pax-8 for distinguishing WDPM from borderline or low-grade serous tumors is unknown. We used immunohistochemistry staining to assess Pax-8 expression in 33 WDPMs, 34 peritoneal MMs, 48 pleural MMs, 11 adenomatoid tumors, 5 peritoneal inclusion cysts, and 51 benign/reactive mesothelium specimens. Staining was noted in 20 WDPMs (61%), with 17 showing strong and diffuse nuclear staining and 3 patchy/focal staining. Calretinin was expressed in 33 cases (100%), whereas focal BerEP4 staining was noted in 2 of 29 cases (7%). In contrast, 4 peritoneal MM (12%) were Pax-8 positive (3 diffuse and 1 focal staining). All adenomatoid tumors and peritoneal inclusion cysts were negative for Pax-8. Of the 48 pleural MM cases, 2 (4%) showed focal weak to moderate nuclear labeling for Pax-8, and 2 cases (4%) of reactive mesothelium demonstrated focal and scattered Pax-8 staining. Pax-8 appears to be a useful marker for distinguishing MM from gynecologic malignancies but is not reliable for distinguishing WDPM from borderline or low-grade gynecologic lesions.

    1981-08-01

    Central serous choroidopathy was observed in a young patient with the Hallermann-Streiff syndrome. Typical features of this syndrome include microphthalmos, proportionate dwarfism, dyscephaly with birdlike facies, dental abnormalities, and hypotrichosis. Exceptional aspects of this case include age of onset (11 years), high hyperopic refractive error (+ 13.00 sphere), and multiple recurrences caused by six separate documented leaks from the choroid. Fundus changes previously reported in the Hallermann-Streiff syndrome, interpreted as chorioretinal pigmentary changes, may have been secondary to previous undiagnosed central serous choroidopathy. Periodic ophthalmoscopy should be performed and may detect unrecognized episodes of central serous choroidopathy for which photocoagulation would be beneficial.

    Full Text Available Fabio MazzolaniPrivate Practice, Milan, ItalyBackground: The purpose of this open-label study was to investigate the effect of a curcumin-phospholipid (lecithin, Meriva® formulation (Norflo® tablet on visual acuity and retinal thickness in patients with acute or chronic central serous chorioretinopathy.Methods: Visual acuity was assessed by ophthalmologic evaluation, and optical coherence tomography was used to measure retinal thickness. Norflo tablets were administered twice a day to patients affected by central serous chorioretinopathy. The study included 18 eyes from 12 patients who completed a 6-month follow-up period. Visual acuity before and after Norflo treatment was the primary endpoint. The secondary endpoints were neuroretinal or pigment epithelial detachment, as measured by optical coherence tomography.Results: After 6 months of therapy, 0% of eyes showed reduction in visual acuity, 39% showed stabilization, and 61% showed improvement. The improvement was statistically significant (P = 0.08. After 6 months of therapy, 78% of eyes showed reduction of neuroretinal or retinal pigment epithelium detachment, 11% showed stabilization, and 11% showed an increase.Conclusion: Our results, albeit preliminary, show that curcumin administered as Norflo tablets is efficacious for the management of central serous chorioretinopathy, a relapsing eye disease, and suggest that bioavailable curcumin is worth considering as a therapeutic agent for the management of inflammatory and degenerative eye conditions, including those that activate the retinal microglia.Keywords: curcumin, central serous chorioretinopathy, retinal pigment epithelium detachment, Norflo®, Meriva®

    Full Text Available Background: Warthin tumor- like papillary carcinoma of thyroid is a rare variant of papillary thyroid carcinoma. It is characterized by distinct papillary structures lined by oncocytic tumor cells with nuclear features of papillary carcinoma and marked lymphoplasmocytic infiltrate in the papillary stalks. This tumor derives its name from its resemblance to Warthin tumor of major salivary glands.Case presentation: We report a 54- year- old man presented with bilateral thyroid masses. Histopathological study showed papillary structures lined by cells with eosinophilic granular cytoplasm and ground- glass nuclei with lymphoplasmacytic infiltration of the stalks.Conclusion: Warthin tumor-like papillary thyroid carcinoma could be mistaken for benign lymphoepithelial lesions such as Hashimoto thyroiditis, Hurthle cell tumors and tall cell variant of papillary carcinoma. Follow- up information on the previously reported cases has suggested that these tumors behave similarly to usual papillary carcinoma.

    Full Text Available Background. To describe the standard autofluorescence (FAF, the near infrared autofluorescence (NIA and optical coherence tomography (OCT patterns in central serous chorioretinopathy, correlating them with fluorescein angiography. Methods. Cross-sectional observational study, in which patients with at least seven months of CSC underwent ophthalmologic examination, fundus photography, FAF, NIA, fluorescein angiography (FA, and spectral-domain OCT. Results. Seventeen eyes of thirteen patients were included. The presentation features were a mottled hyperFAF in the detached area and areas with pigment mottling. NIA images showed areas of hyperNIA similar to FAF and localized areas of hypoNIA, which correlated with the points of leakage in the FA. OCT showed pigment epithelium detachment at the location of these hypoNIA spots. Discussion. FAF showed increased presence of fluorophores in the area of retinal detachment, which is believed to appear secondary to lipofuscin accumulation in the RPE or the presence of debris in the subretinal fluid. NIA has been related to the choroidal melanin content and there were areas of both increased and decreased NIA, which could be explained by damage ahead the retina, basically RPE and choroid. These findings, along with the PEDs found in the areas of hypoNIA, support the notion of a primary choroidal disease in CSC.

  18. Synchronous Parathyroid and Papillary Thyroid Carcinoma

    Full Text Available Concomitant thyroid disease is not unusual among patients with primary hyperparathyroidism. However, the simultaneous occurrence of parathyroid and thyroid carcinoma is extremely rare. We report a 38-year-old man with primary hyperparathyroidism who presented with osteitis fibrosa cystica complicated with pathologic femoral neck fracture. Preoperative investigation for exclusion of multiple endocrine neoplasia did not find evidence of medullary thyroid carcinoma or pheochromocytoma, but imaging studies revealed the presence of nodules in the right lobe and a parathyroid lesion over the left inferior pole of the thyroid gland. Total thyroidectomy, left parathyroidectomy, and bipolar hemiarthroplasty of the left hip were then performed simultaneously. The resected specimens were pathologically identified as papillary thyroid carcinoma and parathyroid carcinoma, respectively. After the operation, 131I ablation therapy was administered at a dose of 120 mCi. Additional doses of 30 mCi were given yearly as serum thyroglobulin level became elevated. Serum calcium level remained normal during yearly follow-up. Although parathyroid carcinoma is an uncommon cause of parathyroid hormone-dependent hypercalcemia, it should nonetheless be given due consideration because its surgical approach differs from that of parathyroid adenoma. As the coexistence of parathyroid and non-medullary thyroid carcinoma has previously been reported, the possibility of both malignancies must also be considered in the setting of primary hyperparathyroidism with thyroid nodules. If confirmed with preoperative parathyroid scintigraphic and other laboratory studies, an optimal outcome may be achieved with complete resection of both tumors at the time of initial operation, followed by adjunctive therapy.

    Although the pathological association of thyroid and parathyroid disease is common, the association of both parathyroid adenoma and thyroid cancer is rare. We report here a case of a 45-year-old saudi women who diagnosed to have primary hyperparathyrodism due to single parathyroid adenoma as confirmed biochemically and radiologically. At operation, the adenoma was found to be an intrathyroid and therefore a thyroid lobectomy was performed. Histology of the excised lobe revealed in addition to the intrathyroid parathyroid adenoma a concurrent occult thyroid papillary carcinoma. The interesting association is discussed based on a literature review. (author)

    A precursor for invasive ovarian/pelvic high-grade serous carcinoma, termed serous tubal intraepithelial carcinoma (STIC), has been identified and characterized through careful analysis of the fallopian tubes in both prophylactic salpingo-oophorectomy specimens obtained from women with either a family history of breast and/or ovarian cancer or germline mutations of BRCA1 and BRCA2 and in cases of pelvic high-grade serous carcinoma. Data on incidental STICs and clinically occult microscopic invasive high-grade serous carcinomas are limited. We analyzed the clinicopathologic features of 22 cases, including 15 pure STICs and 7 STICs associated with microscopic invasive high-grade serous carcinomas, identified incidentally in fallopian tubes removed for nonprophylactic indications. Patient age ranged from 39 to 79 years (mean: 62.7; median: 61), with only 1 patient under the age of 50. No patients were known to carry BRCA1 or BRCA2 mutations. Of the 12 pure STICs for which the location in the fallopian tube could be established, 9 were in the fimbriated portion, 1 was at the junction of the fimbria and infundibulum, and 2 were in the nonfimbriated tube. Of the 7 STICs with associated invasive high-grade serous carcinoma, 3 were located in the fimbriated portion, 2 were at the junction of the fimbria and infundibulum, and 2 were in the nonfimbriated tube. The invasive components were in the fallopian tube in 6 cases, 4 in subepithelial stroma of tubal mucosa, and 2 as an intramucosal (exophytic) luminal lesion without invasion of underlying subepithelial stroma (size range: 1 to 4 mm). The remaining case had a microscopic focus of high-grade serous carcinoma within the ipsilateral ovary (1.3 mm cortical focus) identified only on deeper sections, without an associated invasive component in the fallopian tube. The preferential finding of atypical epithelium with the cytologic features of high-grade serous carcinoma, namely STIC, in the fallopian tubes rather than the

    This review illustrates the varied appearances of benign and malignant papillary breast tumours, as identified by a breast cancer-screening programme. The commonest mammographic appearance of a papillary tumour is as a soft-tissue mass, with calcification present in less than half of cases. When calcification is present the pattern is variable, but clusters of pleomorphic calcification can occur, sometimes resembling the mammographic appearance of invasive ductal carcinoma. Ultrasonography of papillary lesions typically shows a solid, oval, intraductal mass, often associated with duct dilatation. A cystic component is also commonly seen, and lesions may appear hypervascular on colour Doppler ultrasound. Magnetic resonance imaging (MRI) has a high sensitivity, but low specificity for detecting papillary tumours, and is useful in establishing the extent and distribution of lesions in patients with multiple papillomatosis. Despite a benign histology on core biopsy, an argument exists for complete surgical excision of all papillary tumours, as a significant proportion of papillomas will contain foci of atypia or overt malignant change

    Full Text Available Papillary fibroelastomas are cardiac benign tumours. Among the benign cardiac tumor, papillary fibroelastomas are reported second after myxomas. Most often diagnosed incidentally, papillary fibroelastomas may embolize to cerebral circulation. Valvular locations are predominant; location in left atrium is rare. In this paper, we present a case of papillary fibroelastoma located in left atrium with symptoms of cerebral embolization. Transoesophageal echocardiography diagnosed a mobile mass. The patient was treated with surgical resection without further embolic complication.

    2017-06-01

    The goal of this paper is to provide a comprehensive review of the management options for central serous chorioretinopathy (CSCR). The majority of cases of acute CSCR may be managed with observation and cessation of corticosteroids, if possible, as well as life-style modifications including stress reduction and control of hypertension. The management of chronic disease is more challenging and may include either medication or laser-based treatment. Management of CSCR necessitates an individualized and selective treatment approach. There is overall poor evidence for the use of systemic and intravitreal medications. From this class of treatments, mineralocorticoid receptor antagonists appear to have the greatest potential. Although conventional thermal photocoagulation may be used in select cases, the most promising treatment options at this time for chronic CSCR are photodynamic therapy, either half-dose or half-fluence, and non-damaging (subthreshold) retinal laser therapy.

    Full Text Available BACKGROUND: Biomarkers play critical roles in early detection, diagnosis and monitoring of therapeutic outcome and recurrence of cancer. Previous biomarker research on ovarian cancer (OC has mostly focused on the discovery and validation of diagnostic biomarkers. The primary purpose of this study is to identify serum biomarkers for prognosis and therapeutic outcomes of ovarian cancer. EXPERIMENTAL DESIGN: Forty serum proteins were analyzed in 70 serum samples from healthy controls (HC and 101 serum samples from serous OC patients at three different disease phases: post diagnosis (PD, remission (RM and recurrence (RC. The utility of serum proteins as OC biomarkers was evaluated using a variety of statistical methods including survival analysis. RESULTS: Ten serum proteins (PDGF-AB/BB, PDGF-AA, CRP, sFas, CA125, SAA, sTNFRII, sIL-6R, IGFBP6 and MDC have individually good area-under-the-curve (AUC values (AUC = 0.69-0.86 and more than 10 three-marker combinations have excellent AUC values (0.91-0.93 in distinguishing active cancer samples (PD & RC from HC. The mean serum protein levels for RM samples are usually intermediate between HC and OC patients with active cancer (PD & RC. Most importantly, five proteins (sICAM1, RANTES, sgp130, sTNFR-II and sVCAM1 measured at remission can classify, individually and in combination, serous OC patients into two subsets with significantly different overall survival (best HR = 17, p<10(-3. CONCLUSION: We identified five serum proteins which, when measured at remission, can accurately predict the overall survival of serous OC patients, suggesting that they may be useful for monitoring the therapeutic outcomes for ovarian cancer.

    This study sought to evaluate the rate of appendiceal involvement in non-serous mucinous and endometrioid-associated epithelial ovarian cancers. The Manitoba Cancer Registry and CancerCare database were used to find all women with non-serous epithelial ovarian, fallopian tube, or primary peritoneal cancer between 1995 and 2011. All patients with an appendectomy were then identified, and their final pathology findings were reviewed. Women who did not receive treatment or lacked follow-up were excluded. We identified 338 patients from 1995-2011 with no prior appendectomy. Of these, 16.6% received an appendectomy, and 22.8% were clinically evaluated. Most cases within this cohort were mucinous (62%) and stage 1 (63%). Four appendiceal metastases were identified (7.2%), and one half appeared clinically normal at the time of surgery (3.6%). Within the mucinous histologic type, 32.7% of patients received an appendectomy, with a metastatic rate of 5.7%. Of the 127 endometrioid cases, only 10 patients received an appendectomy, and 2 were found to have metastases. No metastases were found in the 85 patients in the clear cell cohort, only 5 of whom received an appendectomy. Routine appendectomy or clinical assessment of the appendix is valuable for all non-serous ovarian cancers. The rate of involvement for endometriosis-associated ovarian cancers may be significantly higher than expected, and further studies need to be conducted.

    Serous tubal intraepithelial carcinomas (STICs) have been documented in high-grade serous ovarian carcinomas (HGSOCs). However, the rate of association between STICs and HGSOCs and, therefore, the fraction of HGSOCs that are likely to have originated from the fallopian tube (FT), has remained unclear. To appraise the literature describing the association between STICs and established HGSOCs. Ovid MEDLINE and EMBASE were searched. Studies were included if they evaluated the frequency of STICs in HGSOCs, and were published in an English peer-reviewed journal. Appropriate studies were evaluated for their compliance with the 'Strengthening and Reporting of Observational Studies in Epidemiology (STROBE)' criteria. Ten articles met the study selection criteria. The reported coexistence between STICs and HGSOCs ranged from 11% to 61% (mean: 31%, 95% CI: 17-46%). STICs were rarely found in other gynaecological cancers. Small sample size, lack of objective criteria to identify STICs and the retrospective nature of the studies contributed to the variability in reporting the rate of the association. STICs were identified commonly in the FTs of women with HGSOC. Finding the true rate of association between STICs and HGSOCs will require further investigations. While there is evidence that a fraction of HGSOCs arise from the FTs, an accurate estimate of that fraction remains to be determined. The lack of an accurate estimate of the association makes it difficult to evaluate the potential magnitude of reduction of HGSOCs following prophylactic salpingectomy. A systematic review of the incidence of STICs in HGSOCs identifies significant methodological inconsistencies. © 2017 Royal College of Obstetricians and Gynaecologists.

Cantù”, Abbiategrasso, Milan, Italy; 3University Eye Clinic, Foundation IRCCS San Matteo Hospital, Pavia, ItalyAbstract: Despite numerous studies describing predominantly its demography and clinical course, many aspects of central serous chorioretinopathy (CSCR remain unclear. Perhaps the major impediment to finding an effective therapy is the difficulty of performing studies with large enough cohorts, which has meant that clinicians have focused more on therapy than on a deeper understanding of the pathogenesis of the disease. Hypotheses on the pathogenesis of CSCR have ranged from a basic alteration in the choroid to an involvement of the retinal pigment epithelium (RPE. Starting from evidence that affected subjects often present a personality prone to stress with altered pituitary–hypothalamic axis response (HPA and that they have higher levels of serum and urinary cortisol and catecholamines than healthy subjects, we hypothesize a cascade of events that may lead to CSCR through hypercoagulability and augmented platelet aggregation. In particular we investigated the role of tissue plasminogen activator, increasing plasminogen activator inhibitor 1 (PAI-1, and plasmin-α2- plasmin inhibitor complexes. We reviewed the different therapeutic approaches, including adrenergic antagonists, carbonic anhydrase inhibitors, mifepristone, ketoconazole, laser photocoagulation, intravitreal injection of bevacizumab, and photodynamic therapy with verteporfin (PDT and our model of pathogenesis seems to be in agreement with the clinical effects obtained from these treatments. In accord with our thesis, we began to treat a group of patients affected by CSCR with low-dose aspirin (75–100 mg, because of its effectiveness in other

    Full Text Available The appearance of a solitary lateral cervical cystic mass as the only initial presenting symptom of occult thyroid carcinoma is uncommon. Its presence is often related with the more frequently branchial cyst in young adults, but also rarely related with thyroid carcinomas. In most of these cases all such lesions may initially be considered as metastatic foci from a primary thyroid lesion. However, an alternative explanation by means of which ectopic thyroid tissue is associated with a branchial cyst has to be considered, especially if no primary tumour is observed in the histological examination of the thyroid gland.

    Full Text Available The appearance of a solitary lateral cervical cystic mass as the only initial presenting symptom of occult thyroid carcinoma is uncommon. Its presence is often related with the more frequently branchial cyst in young adults, but also rarely related with thyroid carcinomas. In most of these cases all such lesions may initially be considered as metastatic foci from a primary thyroid lesion. However, an alternative explanation by means of which ectopic thyroid tissue is associated with a branchial cyst has to be considered, especially if no primary tumour is observed in the histological examination of the thyroid gland. We present two case of solitary cystic lymph node metastasis of occult papillary carcinoma of the thyroid. [Cukurova Med J 2011; 36(1: 29-33

    The intracystic papillary carcinoma is a rare form of mamma cancer, with an incidence of 0.5-1 % of all mamma cancers. It is a tumor predominantly affecting women in advanced age. Although it was believed that this rare entity was a variant of ductal carcinoma in situ, some lesions might be tumors of low risk invasiveness. The tumor has an excellent prognosis despite being in situ or invasive one. Therefore, the precise diagnosis plays an important role in the management of patients with this entity. We report the case of an intracystic papillary carcinoma in a woman aged 75 years. Among other pathological findings, the tumor was 2 cm and was located in the low external quadrant of the right mamma. In the carried out ultrasonography, it was informed an echo lucid image, of well defined edges, and the mammography showed the presence of a nodular image with irregular edges. The histopathologic diagnosis was non-invasive papillary carcinoma, inside a 1 cm cystic lesion, with an 0,5 cm solid nodule inside of low nuclear grade. A wide tumorectomy was carried out. Currently it is controlled. For the elaboration of the current paper we consulted 17 materials of journals and Surgery textbooks. The aim was reporting an intracystic papillary carcinoma case, showing how rare this pathology is for the specialists on the theme. (author)

    Genome sequencing technologies and corresponding oncology publications have generated enormous publicly available datasets for many cancer types. While this has enabled new treatments, and in some limited cases lifetime management of the disease, the treatment options for serous ovarian cancer remain dismal. This review summarizes recent advances in our understanding of ovarian cancer, with a focus on heterogeneity, functional genomics, and actionable data.

    The aim was to evaluate antitumor activity of the combination of ixabepilone and sunitinib in pre-clinical models of chemotherapy naïve and refractory epithelial ovarian tumors, and to investigate the mechanism of synergy of such drug combination. HOVTAX2 cell line was derived from a metastatic serous papillary epithelial ovarian tumor (EOC) and a paclitaxel-resistant derivative was established. Dose response curves for ixabepilone and sunitinib were generated and synergy was determined using combination indexes. The molecular mechanism of antitumor synergy was examined using shRNA silencing. The combination of ixabepilone and sunitinib demonstrated robust antitumor synergy in naïve and paclitaxel-resistant HOVTAX2 cell lines due to increased apoptosis. The GTPase, RhoB, was synergistically upregulated in cells treated with ixabepilone and sunitinib. Using shRNA, RhoB was demonstrated to mediate antitumor synergy. These results were validated in two other EOC cell lines. Ixabepilone plus sunitinib demonstrated antitumor synergy via RhoB in naïve and paclitaxel-resistant cells resulting in apoptosis. This study demonstrates a novel mechanism of action leading to antitumor synergy and provides 'proof-of-principle' for combining molecular targeted agents with cytotoxic chemotherapy to improve antitumor efficacy. RhoB could be envisioned as an early biomarker of response to therapy in a planned Phase II clinical trial to assess the efficacy of ixabepilone combined with a receptor tyrosine kinase inhibitor such as sunitinib. To the best of our knowledge, this is the first demonstration of antitumor synergy between these two classes of drugs in EOC and the pivotal role of RhoB in this synergy.

    The histopathology of papillary thyroid hyperplasia and papillary thyroid carcinoma is similar enough to cause a diagnostic dilemma in a few cases. Both lesions may have papillary fronds with fibrovascular cores, nuclear crowding, and nuclear anisocytosis. Formalin- fixed paraffin-embedded tissues from 30 randomly selected patients with papillary thyroid hyperplasia and an equal number from patients with papillary thyroid carcinoma were analyzed for expression of cytokeratin 19 (CK19), galectin-3, and HBME-1. Cases of papillary thyroid carcinoma had moderate to strong CK19, galectin-3, and HBME-1 reactivity although both CK19 and galectin-3 showed positive staining in a significant number of nonneoplastic thyroid cases. HBME-1 was uncommon in the nonneoplastic cases. These results indicate that HBME-1 may be useful in helping to distinguish papillary thyroid carcinoma from hyperplasia in diagnostically difficult cases.

    Study the manifestations of epidemic process and leading transmission routes of causative agents of enterovirus serous meningitis (SM) by results of laboratory studies and epidemiologic examination of epidemic nidi. During 2010 - 2014 a study for enterovirus was carried out in cerebrospinal fluid in 743 patients, hospitalized into medical organizations of Perm with primary diagnosis "serous meningitis", feces of 426 individuals, that had communicated with patients with SM of enterovirus etiology; 827 water samples from the distribution network, 295 water samples from open water and 57 washes from surface of vegetables and fruits. All the samples were studied in polymerase chain reaction, part--by a virological method. Epidemiologic examination of 350 epidemic nidi of SM was carried out. Enterovirus and (or) its RNA were detected in 62.0% of patients and 61.9% of individuals that had communicated with patients with enteroviris SM. ECHO 6 serotype enterovirus dominated among the causative agents. Maximum intensity of epidemic process of enterovirus SM, based on data from laboratory examination of patients, was detected in a group of organized pre-school and school age children during summer-autumn period. . Examination of epidemic nidi and laboratory control of environmental objects have shown that CV causative agent transmission factors are, in particular, unboiled water from decentralized sources (boreholes, wells, springs), water from open waters during bathing, as well as fresh vegetables, fruits, berries and meals produced from them. .

    There is compelling evidence to suggest that serous tubal intraepithelial carcinoma (STIC) is the likely primary site for the development of many pelvic high-grade serous carcinomas (HGSCs). Identifying molecules that are upregulated in STIC is important not only to provide biomarkers to assist in the diagnosis of STIC but also to elucidate our understanding of the pathogenesis of HGSC. In this study, we performed RNA sequencing to compare transcriptomes between HGSC and normal fallopian tube epithelium (FTE), and we identified LAMC1 encoding laminin γ1 as one of the preferentially upregulated genes associated with HGSC. Reverse transcription polymerase chain reaction further validated LAMC1 upregulation in HGSC as compared with normal FTE. Immunohistochemical analysis was performed on 32 cases of concurrent HGSC and STIC. The latter was diagnosed on the basis of morphology, TP53 mutations, and p53 and Ki-67 immunohistochemical patterns. Laminin γ1 immunostaining intensity was found to be significantly higher in STIC and HGSC compared with adjacent FTE in all cases (PSTIC and HGSC cells, laminin γ1 staining was diffuse and intense throughout the cytoplasm. More importantly, strong laminin γ1 staining was detected in all 13 STICs, which lacked p53 immunoreactivity because of null mutations. These findings suggest that the overexpression of laminin γ1 immunoreactivity and alteration of its staining pattern in STICs can serve as a useful tissue biomarker, especially for those STICs that are negative for p53 and have a low Ki-67 labeling index.

  3. Clinicopathological characteristics of papillary tumor of the pineal region

    Full Text Available Background Papillary tumor of the pineal region (PTPR is a newly recognized distinct entity in the 2007 WHO nomenclature. This tumor is characterized by epithelial-appearing areas with papillary features and more densely cellular areas that often display ependymal-like differentiation, which is likely to originate from the specialized ependymocytes of subcommissural organ near the Sylvian cerebral aqueduct. Due to its rarity and non-specific appearance in radiological exanimation, it is a diagnostic challenge for radiologists and histopathologists to differentiate PTPR from other primary or metastatic lesions located in the pineal region because of their similarities in radiological and histological findings. The aim of this study is to summarize the clinicopathological features of PTPR and discuss the differential diagnosis of histologically similar papillary tumors in pineal region.  Methods The clinical manifestations of a patient with PTPR occurring in supratentorial pineal region were presented retrospectively. Resected mass was routinely paraffin-embedded and stained with hematoxylin and eosin. Dako EnVision immunohistochemical staining system was used to detect the tumor antigen expressions, including vimentin (Vim, glial fibrillary acidic protein (GFAP, S-100 protein (S-100, pan cytokeratin (PCK, cytokeratin 7 (CK7, CK20, epithelial membrane antigen (EMA, neuronal nuclear antigen (NeuN, synaptophysin (Syn, neuron-specific enolase (NSE, and Ki-67 labeling index (MIB-1.  Results A 57-year-old male patient presented with 6-month history of mild headache, and became severe in last one month. MRI revealed a solid well-circumscribed lesion in supratentorial midline near the pineal region and the posterior third ventricle with mild heterogeneous enhancement. Craniotomy was performed and the tumor was removed totally. Histological examination revealed that the lesion contained papillary areas lined by columnar epithelioid tumor cells with

    Serous goblet cells in the oral epithelium of Rita rita are characterized by the presence of distinct eosinophilic granules occupying large parts of the cytoplasm. In R. rita, a range of histochemical results reveal that these cells are involved in proteinaceous secretions, and thus likely contribute to various functions analogous to those of mammalian saliva. The secretions of these cells have also been associated with specific functions and are discussed in relation to their physiological importance with special reference to their roles in lubrication, alteration in viscosity, various functions of mucus such as handling, maneuvering and driving of food items toward the esophagus, maintaining taste sensitivity and protection of the oral epithelium. In addition, the serous goblet cells may also be considered as the primary defensive cell of the oral epithelium of R. rita. The results significantly add to very limited set of literature on the serous goblet cells and provide noteworthy information on the mucous secretions in the oral cavity of fish.

    Full Text Available Context: High-grade serous carcinomas of ovarian, tubal, and peritoneal origin are together referred as pelvic serous carcinoma. The fallopian tubes, ovarian surface epithelium, and the tuboperitoneal junctional epithelium are all implicated in pelvic serous carcinogenesis. Aims: The aim of this study is to identify putative precursor lesions of serous carcinoma including secretory cell outgrowths (SCOUTs, serous tubal intraepithelial carcinoma (STIC, and p53 signatures and assign its probable site of origin. Settings and Design: Prospective case-control study of consecutive specimen comprising 32 serous carcinomas and 31 controls (10 normal adnexa, 10 benign and 6 atypically proliferative surface epithelial tumors, and 5 other carcinomas. Subjects and Methods: Sectioning and extensive examination of the fimbrial end (SEE-FIM protocol along with immunohistochemistry for Bcl-2, p53, and Ki-67 was employed for evaluating invasive carcinoma and precursor lesions in cases versus controls. Results: SCOUT, p53 signatures, and STIC were most frequent in the serous carcinomas. p53 signatures and STIC were always seen in the fimbrial end. STICs were exclusively present in serous carcinomas, more common in ipsilateral tubes of cases with dominant ovarian mass. Multifocal p53 signatures with STIC were seen in 7 (21.9% cases. STIC was present with or without an invasive carcinoma in 25% and in 6.25% of cases of pelvic serous carcinomas, respectively. The junctional epithelia did not show any lesion in any group. Conclusions: SEE-FIM protocol is recommended for evaluation of sporadicpelvic (ovarian/tubal/peritoneal serous carcinoma. Based on the presence of STIC or invasive carcinoma, nearly 60% of all pelvic serous carcinomas are of fallopian tubal origin.

    Serous tubal intraepithelial carcinomas (STICs) have been proposed to be the most likely precursor of ovarian, tubal and ‘primary peritoneal’ (pelvic) high-grade serous carcinoma (HGSC). As somatic mutation of TP53 is the most common molecular genetic change of ovarian HGSC, occurring in more than 95% of cases, we undertook a mutational analysis of 29 pelvic HGSCs that had concurrent STICs to demonstrate the clonal relationship of STICs and HGSCs. In addition, we correlated the mutational data with p53 immunostaining to determine the role of p53 immunoreactivity as a surrogate for TP53 mutations in histological diagnosis. Somatic TP53 mutations were detected in all 29 HGSCs analysed and the identical mutations were detected in 27 of 29 pairs of STICs and concurrent HGSCs. Missense mutations were observed in 61% of STICs and frameshift/splicing junction/nonsense mutations in 39%. Interestingly, there were two HGSCs with two distinctly different TP53 mutations each, but only one of the mutations was detected in the concurrent STICs. Missense mutations were associated with intense and diffuse (≥ 60%) p53 nuclear immunoreactivity, while most of the null mutations were associated with complete loss of p53 staining (p STIC and pelvic HGSC and demonstrate the utility of p53 immunostaining as a surrogate for TP53 mutation in the histological diagnosis of STIC. In this regard, it is important to appreciate the significance of different staining patterns. Specifically, strong diffuse staining correlates with a missense mutation, whereas complete absence of staining correlates with null mutations. PMID:21990067

    The natural history and optimal management of serous tubal intraepithelial carcinoma (STIC), regardless of BRCA status, is unknown. We report the follow-up findings of a series of incidental fallopian tube high-grade serous carcinomas (HGSCs) and STICs identified in women at low risk for hereditary breast and ovarian cancer (HBOC), undergoing surgery for other indications. Cases of incidental STIC and HGSC were identified from 2008. Patients with known BRCA1 or BRCA2 mutations, or a family history of ovarian or breast cancer before the diagnosis of STIC or HGSC were excluded. A retrospective chart review was conducted to obtain clinical data. Eighteen cases were identified with a median follow-up of 25 months (range, 4-88 months). Twelve of 18 patients had a diagnosis of STIC with no associated invasive HGSC and 6 had STIC associated with other invasive malignancies. Completion staging surgery was performed on 7 of the 18 patients, including 5 of 12 in which there was STIC only identified on primary surgery; 3 cases were upstaged from STIC only to HGSC based on the staging surgery. Recurrence of HGSC occurred in 2 of the 18 patients. BRCA testing was performed on 3 patients, 1 of whom tested positive for a pathogenic BRCA1 mutation. Our study suggests that completion staging surgery for incidental STICs in non-BRCA patients may be considered. These patients should be offered hereditary testing. The Pelvic-Ovarian cancer INTerception (POINT) Project is an international registry set up to add to our understanding of STICs.

    Mesothelial papillary hyperplasia (MPH) has been described as an incidental finding on the epicardial surface of clinically normal laboratory Beagle dogs. We describe MPH in 4 dogs diagnosed with acute cardiac tamponade (1 case) or chronic cardiac disease (3 cases). Cardiac MPH appeared as distinct, soft, irregular villous plaques on the epicardial surface of the auricles and occasionally the ventricles. Histologically, areas of MPH were composed of multiple papillary fronds arising from the epicardial surface and projecting into the pericardial space. Fronds were covered by cuboidal and occasionally vacuolated mesothelial cells and were supported by loose fibrovascular stroma with various degrees of edema and inflammation. Although these may represent incidental findings with no clinical significance, the gross appearance warrants differentiation from other conditions. Additional insight into the pathogenesis of MPH is needed to fully understand its significance in the face of concurrent cardiac disease.

    Papillary renal cell carcinoma is a subgroup of malignant renal epithelial neoplasms. Its occurrence in allograft transplanted kidney has not been debated in the literature. We report two pathologically proven cases and discuss the clinical hypothesis for such neoplasms and the aspect on MR images. The paramagnetic effect of the iron associated with an absence of signal coming from calcifications is a plausible explanation for this unusual hypointense appearance on T2-weighted sequence.

    Full Text Available Abstract Background Collision tumors of the thyroid gland are a rare entity. We present a case of a follicular variant of papillary carcinoma and squamous carcinoma in the thyroid. To the best of our knowledge, this is the first documentation of a collision tumor with a papillary carcinoma and a squamous carcinoma within the thyroid gland. The clinicopathological features and immunohistochemical profile are reported. The theories of origin, epidemiology and management are discussed with a literature review. Case presentation A 65 year old woman presented with a large thyroid swelling of 10 years duration and with swellings on the back and scalp which were diagnosed to be a follicular variant of papillary thyroid carcinoma with metastasis. Clinical examination, radiology and endoscopy ruled out any other abnormality of the upper aerodigestive tract. The patient was treated surgically with a total thyroidectomy with central compartment clearance and bilateral selective neck dissections. The histopathology revealed a collision tumor with components of both a follicular variant of papillary carcinoma and a squamous carcinoma. Immunohistochemical analysis confirmed the independent origin of these two primary tumors. Adjuvant radio iodine therapy directed toward the follicular derived component of the thyroid tumor and external beam radiotherapy for the squamous component was planned. Conclusion Collision tumors of the thyroid gland pose a diagnostic as well as therapeutic challenge. Metastasis from distant organs and contiguous primary tumors should be excluded. The origins of squamous cancer in the thyroid gland must be established to support the true evolution of a collision tumor and to plan treatment. Treatment for collision tumors depends upon the combination of primary tumors involved and each component of the combination should be treated like an independent primary. The reporting of similar cases with longer follow-up will help define the

    High-grade serous ovarian carcinoma (HGSOC) is the most frequent type of ovarian cancer and has a poor outcome. It has been proposed that fallopian tube cancers may be precursors of HGSOC but evolutionary evidence for this hypothesis has been limited. Here, we perform whole-exome sequence and copy number analyses of laser capture microdissected fallopian tube lesions (p53 signatures, serous tubal intraepithelial carcinomas (STICs), and fallopian tube carcinomas), ovarian cancers, and metastases from nine patients. The majority of tumor-specific alterations in ovarian cancers were present in STICs, including those affecting TP53, BRCA1, BRCA2 or PTEN. Evolutionary analyses reveal that p53 signatures and STICs are precursors of ovarian carcinoma and identify a window of 7 years between development of a STIC and initiation of ovarian carcinoma, with metastases following rapidly thereafter. Our results provide insights into the etiology of ovarian cancer and have implications for prevention, early detection and therapeutic intervention of this disease.

    The purpose of this study was to report a case of a woman with nephrotic syndrome who presented with blurred vision because of bilateral serous macular detachment. Case report and literature review. A 55-year-old woman with a history of essential hypertension, diabetes, and nephrotic syndrome was presented with blurred vision in both eyes. Her fluorescein angiography revealed dye leakage in the early and subretinal pooling in the late phases, and optical coherence tomography scans confirmed the presence of subretinal fluid in the subfovel area. In nephrotic syndrome cases especially with accompaniment of high blood pressure, fluid accumulation in the retina layer may occur. Serous macular detachment must be kept in mind when treating these patients.

    Dual malignancy is rare in adolescents. Dual malignancy with the second malignancy of thyroid is rare.

    The analysis of surgical treatment of 300 patients of children and adolescent ages with papillary thyroid carcinoma has shown in the paper. It has been noticed that at the time after the Chernobyl accident the majority of thyroid carcinomas in children and adolescents has been characterized with the combined solid-follicular variants of structure with the expressed aggressive properties: early lymphogenic metastasis and local invasiveness of primary tumor. The method of radical treatment for patients of children and adolescent ages with papillary thyroid cancer was thyroidectomy with the following radioiodine therapy and suppressive therapy with the thyroid hormones

    Studies on the immunophenotypes of early forms of serous carcinoma arising from female genital tract are limited. We aimed to examine p53, p16(Ink4a), estrogen receptor (ER), progesterone receptor (PR), ERBB2, WT1, and Ki-67 protein expression in endometrial intraepithelial carcinoma (n=29), serous tubal intraepithelial lesion (n=4) and carcinoma (STIC, n=10), and the putative precursor p53 signature (n=11). Among endometrial intraepithelial carcinoma, 80% demonstrated p53 overexpression and 10% were consistent with a null phenotype. p16(Ink4a) immunostaining were observed in all endometrial intraepithelial carcinoma cases. ER, PR, ERBB2, and WT1 were positive in 54%, 25%, 11%, and 18% of cases, respectively. STIC cases demonstrated p53 overexpression and null phenotype in 90% and 10%, respectively. All STIC cases were p16(Ink4a) and WT1 positive, whereas ER and PR were positive in 70% and 20%, respectively. All STICs were negative for ERBB2. Among serous tubal intraepithelial lesion cases, 75% demonstrated p53 overexpression and 25% a null phenotype. p53 was positive in all 11 p53 signature cases, whereas p16(Ink4a) was universally negative. Finally, ER and PR were positive in 100% and 73% of p53 signature cases, respectively. These results suggest that p16(Ink4a) has a role in early Müllerian serous carcinogenesis but is absent in the earliest noncommitted lesion. p16(Ink4a) immunohistochemistry can be used as an adjunct confirmatory tool in p53-null cases with limited surface area.

    Brain metastases from differentiated thyroid carcinoma are extremely rare and carry a poor prognosis. We describe here clinical details of 7 cases of brain metastases from papillary thyroid carcinoma. Of 153 patients with metastases from differentiated thyroid carcinoma (papillary in 123, follicular in 30) treated at our institution between 1981 and 1999, 7 patients (4.6%) had brain metastases. Histologically, the primary tumor was papillary carcinoma in all 7 cases. Four were males and 3 were females. The median age at first diagnosis of distant metastases was 63 yr (range, 47-76 yr). Of these patients, one had brain metastases only and six and metastases to the lungs as well. Five of these patients were treated with 131 I. Three of these 5 patients had marked uptake in the metastases ( 131 I positive) on post-therapy 131 I scans and another 2 patients had no significant activity ( 131 I negative) in both pulmonary and brain metastatic lesions. One of 3 patients with 131 I positive lesions had intense activity in the brain tumor, but no uptake in multiple pulmonary metastatic tumors. In a patient with 131 I positive brain metastases, the tumors progressed rapidly after 131 I therapy. In another one patient, acute hemorrhage of the tumor occurred four days after 131 I therapy, requiring surgical removal. Loner case of 131 I negative 2 patients was treated with radiosurgery (γ-knife) and complete reduction in tumor volume was observed. On the other hand, one of 2 patients receiving no 131 I therapy had radiosurgery (x-knife) and remaining one received conventional external radiation and chemotherapy for small solitary brain and pulmonary metastatic tumors. These therapeutic interventions were useful in both cases. The mean length of survival after the development of brain metastases in the five patients who died of the disease was 30 months. One patient treated with x-knife has been alive at 21 months and another one who has 131 I uptake in the brain tumor without

    Many high-grade serous carcinomas (HGSCs) of the pelvis are thought to originate in the distal portion of the fallopian tube. Serous tubal intra-epithelial carcinoma (STIC) lesions are the putative precursor to HGSC and identifiable in ~ 50% of advanced stage cases. To better understand the molecular etiology of HGSCs, we report a multi-center integrated genomic analysis of advanced stage tumors with and without STIC lesions and normal tissues. The most significant focal DNA SCNAs were shared between cases with and without STIC lesions. The RNA sequence and the miRNA data did not identify any clear separation between cases with and without STIC lesions. HGSCs had molecular profiles more similar to normal fallopian tube epithelium than ovarian surface epithelium or peritoneum. The data suggest that the molecular features of HGSCs with and without associated STIC lesions are mostly shared, indicating a common biologic origin, likely to be the distal fallopian tube among all cases.High-grade serous carcinomas (HGSCs) are associated with precursor lesions (STICs) in the fallopian epithelium in only half of the cases. Here the authors report the molecular analysis of HGSCs with and without associated STICs and show similar profiles supporting a common origin for all HGSCs.

    African Journals Online (AJOL)

    Introduction and objectives: Papillary renal cell carcinoma (PRCC) accounts for 10–15% of renal tumors in adults. This type of tumor contains more than 75% of tubulo-papillary structures and is divided histologically into two subtypes. The distinction between these two subtypes is essential because of their prognostic value.

    Full Text Available Background. Thyroid carcinoma is a relatively rare pediatric pathology, comprising around 3% of all childhood tumors. We investigated parameters of tumor aggressiveness, multicentricity, and locoregional metastatic spread patterns in patients up to 18 years of age and made comparison with the older group. All patients were operated upon with total thyroidectomy, with or without lymph-node neck dissection. Results. Patients with papillary carcinoma present with more advanced stage, larger primary tumor, and more commonly present with palpable thyroid and/or neck node. Overall, papillary cancer demonstrated pathological aggressiveness as defined by our criteria in 60%, multicentricity in 40%, and locoregional metastatic foci in 77% of cases. Multicentric tumor foci in both thyroid lobes and tumor aggressiveness were identified as a risk factor for metastatic development. Conclusion. By observing clinicopathological parameters, we demonstrated that papillary thyroid cancer behaves more aggressively in the younger group. We recommend total thyroidectomy with careful intraoperative exploration of thyroid bed and lateral neck in search for possible metastatic spread. In case of positive findings, it is obligatory to perform a standard neck dissection, keeping in mind that neck lymphonodes are primary site of locoregional recurrence. With meticulous attention to technical aspects of operation, perioperative morbidity should be minimal.

    Ultrasonography (US) is routinely used to evaluate thyroid nodules. The US features of papillary thyroid carcinoma (PTC), the most common thyroid malignancy, include hypoechogenicity, spiculated/microlobulated margins, microcalcifications, and a nonparallel orientation. However, many PTC variants have been identified, some of which differ from the classic type of PTC in terms of biological behavior and clinical outcomes. This review describes the US features and clinical implications of the variants of PTC. With the introduction of active surveillance replacing immediate biopsy or surgical treatment of indolent, small PTCs, an understanding of the US characteristics of PTC variants will facilitate the individualized management of patients with PTC.

    2009-01-01

    BACKGROUND Whether an oncofetal protein, IMP3, can serve as a prognostic biomarker to predict metastasis for patients with localized papillary and chromophobe subtypes of renal cell carcinomas (RCCs) was investigated. METHODS The expression of IMP3 in 334 patients with primary papillary and chromophobe RCC from multiple medical centers was evaluated by immunohistochemistry. The 317 patients with localized papillary and chromophobe RCCs were further evaluated for outcome analyses. RESULTS IMP3 was significantly increased in a subset of localized papillary and chromophobe RCCs that subsequently metastasized. Patients with localized IMP3-positive tumors (n = 33; 10%) were over 10 times more likely to metastasize (risk ratio [RR], 11.38; 95% confidence interval [CI], 5.40–23.96; P <.001) and were nearly twice as likely to die (RR, 1.91; 95% CI, 1.13–3.22; P =.016) compared with patients with localized IMP3 negative tumors. The 5-year metastasis-free and overall survival rates were 64% and 58% for patients with IMP3-positive localized papillary and chromophobe RCCs compared with 98% and 85% for patients with IMP3 negative tumors, respectively. In multivariable analysis adjusting for the TNM stage and nuclear grade, patients with IMP3-positive tumors were still over 10 times more likely to progress to distant metastasis (RR, 13.45; 95% CI, 6.00–30.14; P <.001) and were still nearly twice as likely die (RR, 1.95; 95% CI, 1.15–3.31; P =.013) compared with patients with IMP3-negative tumors. CONCLUSIONS IMP3 is an independent prognostic biomarker that can be used to identify a subgroup of patients with localized papillary and chromophobe RCC who are at high risk for developing distant metastasis.

    We compared survival outcomes of advanced serous type epithelial ovarian cancer (EOC) patients with normal-sized ovaries and enlarged-ovarian tumors by propensity score matching analysis. The medical records of EOC patients treated at Samsung Medical Center between 2002 and 2015 were reviewed retrospectively. We investigated EOC patients with high grade serous type histology and International Federation of Gynecology and Obstetrics (FIGO) stage IIIB, IIIC, or IV who underwent primary debulking surgery (PDS) and adjuvant chemotherapy to identify patients with normal-sized ovaries. Propensity score matching was performed to compare patients with normal-sized ovaries to patients with enlarged-ovarian tumors (ratio, 1:3) according to age, FIGO stage, initial cancer antigen (CA)-125 level, and residual disease status after PDS. Of the 419 EOC patients, 48 patients had normal-sized ovary. Patients with enlarged-ovarian tumor were younger (54.0±10.3 vs. 58.4±9.2 years, p=0.005) than those with normal-sized ovary, and there was a statistically significant difference in residual disease status between the 2 groups. In total cohort with a median follow-up period of 43 months (range, 3-164 months), inferior overall survival (OS) was shown in the normal-sized ovary group (median OS, 71.2 vs. 41.4 months; p=0.003). After propensity score matching, the group with normal-sized ovary showed inferior OS compared to the group with enlarged-ovarian tumor (median OS, 72.1 vs. 41.4 months; p=0.031). In multivariate analysis for OS, normal-sized ovary remained a significant factor. Normal-sized ovary was associated with poor OS compared with the common presentation of enlarged ovaries in EOC, independent of CA-125 level or residual disease. Copyright © 2018.

    Serous tubal intraepithelial carcinoma (STIC) has been proposed as a precursor for many pelvic high-grade serous carcinomas. Our previous analysis of the ovarian cancer genome identified several genes with oncogenic potential that are amplified and/or overexpressed in the majority of high-grade serous carcinomas. Determining whether these genes are upregulated in STICs is important in further elucidating the relationship of STICs to high-grade serous carcinomas and is fundamental in understanding the molecular pathogenesis of high-grade serous carcinomas. In this study, 37 morphologically defined STICs were obtained from 23 patients with stage IIIC/IV high-grade serous carcinomas. Both STICs and the high-grade serous carcinomas were analyzed for expression of Rsf-1 (HBXAP), cyclin E, fatty acid synthase (FASN) and mucin-4. In addition, they were examined for expression of established markers including p53, Ki-67 and p16. We found that diffuse nuclear p53 and p16 immunoreactivity was observed in 27 (75%) of 36 and 18 (55%) of 33 STICs, respectively, whereas an elevated Ki-67 labeling index (>or=10%) was detected in 29 (78%) of 37 STICs. Cyclin E nuclear staining was seen in 24 (77%) of 35 STICs, whereas normal tubal epithelial cells were all negative. Increased Rsf-1 and FASN immunoreactivity occurred in 63%, and 62% of STICs, respectively, compared with adjacent normal-appearing tubal epithelium. Interestingly, only one STIC showed increased mucin-4 immunoreactivity. Carcinomas, when compared with STICs, overexpressed p16, Rsf-1, cyclin E and FASN in a higher proportion of cases. In conclusion, STICs express several markers including Rsf-1, cyclin E and FASN in high-grade serous carcinomas. In contrast, mucin-4 immunoreactivity either did not change or was reduced in most STICs. These results suggest that overexpression of Rsf-1, cyclin E and FASN occurs early in tumor progression.

    The intravascular papillary endothelial hyperplasia (IPEH/Masson's tumor) is a rare benign tumor of the skin and subcutaneous vessels. We report, in four pediatric cases, clinical presentation, care (diagnostic and surgical) of Masson's tumor in children. Two boys (two years) and two girls (four and six years) showed a pain subcutaneous tumor (one to five centimeters). They were in the transverse abdominal muscle, between two metatarsals, at the front of thigh and in the axilla. Imaging performed (MRI, Doppler ultrasound) evoked either a hematoma, a lymphangioma or hemangioma. The indication for removal was selected from pain and/or parental concern. The diagnosis was histologically. A lesion persisted in residual form (incomplete initial resection), and is currently not scalable for eleven years. This tumor is characterized by excessive proliferation and papillary endothelial cells in the vessels, following a thrombotic event. It is found mainly in adults (no specific age), and preferentially localizes in the face and limbs. The clinical differential diagnosis of this tumor is angiosarcoma. The imagery has not allowed in our series to diagnose but still essential to eliminate differential diagnoses. Only surgical excision with histological examination can differentiate. Our study emphasizes the possibility of pediatric cases with two cases of unusual locations (abdominal and axilla). Clinical presentations we met, now lead us to direct our histologist looking for a Masson tumor in any child with a subcutaneous tumor and/or intramuscular pain, sudden onset, and vascular appearance (after excluding an arteriovenous malformation).

Nation-wide population-based study of women≥18years with histologically verified non-uterine serous cancer, included in the Swedish Quality Registry for primary cancer of the ovary, fallopian tube and peritoneum diagnosed 2009-2013. Relative survival (RS) was estimated using the Ederer II method. Simple and multivariable analyses were estimated by Poisson regression models. Of 5627 women identified, 1246 (22%) had borderline tumors and 4381 had malignant tumors. In total, 2359 women had serous cancer; 71% originated in the ovary (OC), 9% in the fallopian tube (FTC), 9% in the peritoneum (PPC) and 11% at an undesignated primary site (UPS). Estimated RS at 5-years was 37%; for FTC 54%, 40% for OC, 34% for PPC and 13% for UPS. In multivariable regression analyses restricted to women who had undergone primary or interval debulking surgery for OC, FTC and PPC, site of origin was not independently associated with survival. Significant associations with worse survival were found for advanced stages (RR 2.63, Pcancer at UPS than for ovarian, fallopian tube and peritoneal cancer.

    Full Text Available Background Endolymphatic sac tumor (ELST is a rare tumor originating fromendolymphatic epithelium of inner ear. This tumor exhibits low-grade malignancy with benign histopathological appearance and clinically destructive behavior which occurs in the skull base and frequently invades the posterior petrous bone, the mastoid, semicircular canal, cerebellopontine angle structures and cranial nerve. The presence of intracranial ELST always makes the diagnosis challenge for clinicians and pathologists. Herein we describe a case of ELST in skull base. The clinicopathology of this tumor and its differential diagnosis are discussed. Methods The clinical manifestation of a patient with primary ELST occurring in right cerebellopontine angle was presented retrospectively. Resected mass was routinely paraffin-embedded and stained with hematoxylin and eosin. Dako EnVision immunohistochemical staining system was used to detect the tumor antigen expressions, including cytokeratin (CK, vimentin (Vim, epithelial membrane antigen (EMA, carcinoembryonic antigen (CEA, synaptophysin (Syn, chromogranin A (CgA, S-100 protein (S-100, glial fibrillary acidic protein (GFAP, thyroglobulin (TG, thyroid transcription factor-1 (TTF-1 and Ki-67. Results A 32-year-old male patient presented with 20-year history of progressive hearing loss. MRI scan revealed an expansile lytic lesion of the mastoid process of the right petrous bone, measuring 4.20 cm × 3.30 cm × 2.00 cm, occupied the right cerebellopontine angle with infiltration of surrounding dura mater. But the lesion did not break the dura mater and invade the brain parenchyma. Craniotomy was performed and the tumor was removed totally. Histological examination revealed a papillary, cystic or glandular architecture in mass. The papillary and glandular structures were lined by a single layer of flattened cuboidal-to-columnar cells. The stroma of the papillary fronds was richly vascularized and chronically inflamed. There

    Short telomeres are one of the main genetic manifestations in human cancer, as they have been shown to play an important role in inducing chromosomal instability and in contributing to tumor progression. The purpose of this study was to determine if changes in telomere length occur in serous tubal intraepithelial carcinoma (STIC), the putative precursor of "ovarian" high-grade serous carcinoma (HGSC). Twenty-two STICs from 15 patients with concurrent but discrete HGSCs were analyzed for telomere length on formalin-fixed, paraffin-embedded sections by conducting p53 immunofluorescence to assist in identifying STICs and telomere-specific FISH. Telomere length (short, long, or no change) in STICs was compared with HGSCs using normal fallopian tube epithelium and stromal cells as controls. We found that STICs had the shortest telomeres, as 18 (82%) of 22 STICs had short telomeres, whereas only 2 (9%) showed no change and 2 (9%) had long telomeres compared with the normal-looking tubal epithelium. In contrast, among 12 paired HGSCs and STICs, 6 HGSCs showed an increase in telomere length, one showed a decrease in length and 5 did not show any change when compared with their matched STICs, although, such as STICs, the majority of HGSCs had shorter telomeres than the associated normal tubal epithelial cells. These differences in telomere length between normal tubal epithelial cells and STICs, and between STICs and HGSCs were statisticaly significant (PSTICs provides further support to the proposal that STICs are precursors of HGSC and opens new areas of research in elucidating the early events of ovarian high-grade serous carcinogenesis.

    Full Text Available Abstract The prevalence of primary cardiac tumour ranges from 0.0017-0.28% and papillary fibroelastoma is rare but not uncommon benign cardiac neoplasm. Currently, with the advent of higher-resolution imaging technology especially transoesophageal echocardiography such cases being recognized frequently. The clinical presentation of these tumours varies from asymptomatic to severe ischaemic or embolic complications. We herein, present a 50-year-old female patient with a papillary fibroelastoma of the aortic valve arising from the endocardium of the right coronary cusp very close to the commissure between the right and non-coronary cusps. The patient presented with angina-like chest pain and was investigated using echocardiography and CT angiographic modalities in addition to the usual investigations. The differential diagnosis considered was a thrombus, myxoma, Lambl's excrescence and infective vegetation. The surgical management included a prompt resection of the tumour on cardiopulmonary bypass avoiding injury to the aortic valve. The patient recovered well. A review of the literature suggests that the cardiac papillary fibroelastoma is a rare but potentially treatable cause of embolic stroke and other fatal complications, therefore, a strong suspicion; appropriate use of imaging modality, preoperative anticoagulation and urgent surgical resection is warranted. Also, possibility of this diagnosis should be kept in mind while managing cardiac or valvular tumours.

Among the low-grade serous carcinomas, there is a high frequency of activating mutations in the KRAS or BRAF genes; however, it remains unclear as to how these mutations contribute to tumor progression. This is the first report to track the histopathological progression of serous adenofibroma to low-grade serous carcinoma. Each stage was individually analyzed by pathological and molecular genetic methods to determine what differences occur between the distinct stages of progression.

    Central serous chorioretinopathy (CSR) is a serous detachment of the neurosensory retina commonly associated with male sex, Type-A personality and corticosteroid use. Exogenous administration of androgens and development of CSR in men has been reported. Only one case of CSR in a postmenopausal woman receiving exogenous androgen therapy has been reported. The authors describe three cases of chronic CSR in postmenopausal women receiving exogenous testosterone therapy. Diagnosis was based on characteristic clinical, fluorescein angiographic, and optical coherence tomography findings. The three women were being treated with exogenous testosterone and progesterone therapy for symptoms of menopause and libido loss. Average age at presentation was 54.7 years (53-56 years), average duration of exogenous androgen use was 61 months (36-87 months), with average 19.7-month follow-up. Resolution of symptoms seemed correlated with cessation of androgen use despite treatment with oscillatory photodynamic therapy and intravitreal pharmacotherapy with antivascular endothelial growth factor agents. Exogenous testosterone is increasingly prescribed for menopausal symptoms and libido loss. Treatment with oscillatory photodynamic therapy, supplemental bevacizumab intravitreal pharmacotherapy, and cessation of exogenous androgen therapy was successful in three cases of chronic, therapy-resistant CSR. Ophthalmologists should inquire about androgen usage in patients who present with CSR, especially in the setting of therapy resistance.

    Diffuse sclerosing papillary carcinoma (DSPC) is a variant of papillary thyroid carcinoma (PTC), but it shows more aggressive clinical course and a poorer prognosis than the other types of PTC. Most PTCs show a focal nodular pattern in the thyroid on the imaging modalities, but DSPC reveals a diffuse infiltrating configuration in the thyroid without any focal nodular lesion. To our knowledge, there are scant radiological reports of diffuse sclerosing variant of papillary thyroid carcinoma. In this report, we present the case of a patient with DSPC who showed the characteristic findings on sonography and computed tomography

    Full Text Available Papillary thyroid carcinoma is the most common form of differentiated thyroid carcinoma. It is generally confined to the neck with or without spread to regional lymph nodes. Metastatic thyroid carcinomas are uncommon and mainly include lung and bone. Metastases involving oral and maxillofacial region are extremely rare. We described a case of malar metastasis revealing a follicular variant of papillary thyroid carcinoma, presenting with pain and swelling of the left cheek in a 67-years-old female patient with an unspecified histological left lobo-isthmectomy medical history. To our knowledge, this is the first recorded instance of a malar metastasis from a follicular variant of papillary thyroid carcinoma.

    Outcomes of metastatic papillary renal cell carcinoma (pRCC) patients are poorly characterized in the era of targeted therapy. A total of 5474 patients with metastatic renal cell carcinoma (mRCC) in the International mRCC Database Consortium (IMDC) were retrospectively analyzed. Outcomes were...... compared between clear cell (ccRCC; n = 5008) and papillary patients (n = 466), and recorded type I and type II papillary patients (n = 30 and n = 165, respectively). Overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) favored ccRCC over pRCC. OS was 8 months longer...

    The aim of this review is to describe the different imaging appearances of benign and malignant papillary breast lesions on mammography, ultrasound, and magnetic resonance imaging, according to the World Health Organization histopathological classifications. The classification and morphological imaging characteristics of papillary lesions remain challenging for pathologists and radiologists. Despite the difficulty of classifying these lesions, our review and those of others suggest that morphology is associated with clinically meaningful staging and outcome implications. Imaging can help to differentiate the forms of papillary lesion, but surgical specimens are required for definitive diagnosis in the majority of cases

  4. Renal papillary calcification and the development of calcium oxalate monohydrate papillary renal calculi: a case series study

    Science.gov (United States)

    2013-01-01

    Background The objective of this study is to determine in a case series (four patients) how calcified deposits in renal papillae are associated with the development of calcium oxalate monohydrate (COM) papillary calculi. Methods From the recently collected papillary calculi, we evaluated retrospectively patients, subjected to retrograde ureteroscopy, with COM papillary lithiasis. Results The COM papillary calculi were found to result from subepithelial injury. Many of these lesions underwent calcification by hydroxyapatite (HAP), with calculus morphology and the amount of HAP in the concave zone dependent on the location of the calcified injury. Most of these HAP deposits grew, eroding the epithelium covering the renal papillae, coming into contact with urine and starting the development of COM calculi. Subepithelial HAP plaques may alter the epithelium covering the papillae, resulting in the deposit of COM crystals directly onto the epithelium. Tissue calcification depends on a pre-existing injury, the continuation of this process is due to modulators and/or crystallization inhibitors deficiency. Conclusions Since calculus morphology and the amount of detected HAP are dependent on the location and widespread of calcified injury, all types of papillary COM calculi can be found in the same patient. All patients had subepithelial calcifications, with fewer papillary calculi, demonstrating that some subepithelial calcifications did not further evolve and were reabsorbed. A high number of subepithelial calcifications increases the likelihood that some will be transformed into COM papillary calculi. PMID:23497010

    Full Text Available Cardiac papillary fibroelastomas (CPF are rare cardiac tumors, mostly found on the valvular surfaces in the heart. These tumors are frond like in nature and are benign, intracardiac masses, rarely causing any hemodynamic disturbances. However, excision of these masses is indicated due to their propensity to embolize. We present a case report of the tumor found on the coumadin ridge, causing transient ischemic attacks in a patient. We performed complete excision of the tumor via median sternotomy on cardiopulmonary bypass support with cardiac arrest. The diagnosis was confirmed by histological examination. The patient had an uneventful postoperative course and was discharghed on postoperative day 4. She has had complete resolution of her symptoms post excision. The diagnosis of the mass was confirmed on histological examination.

    An 11-year-old female German Shepherd dog was presented for investigation of progressive enlargement of the abdomen, periodic bloody discharge from the vulva and rapid exhaustion. Transabdominal ultrasonography and lateral abdominal radiography demonstrated an echogenic formation with anechogenic cavities located cranial to the urinary bladder and a homogeneous shadow with an elliptical shape was located caudal to the rib arc. Both showed indistinct borders. Exploratory laparotomy identified bilateral ovarian masses and ovariohysterectomy was performed. Histopathology confirmed ovarian cystadenocarcinoma. The dog remained clinically normal without evidence of metastatic disease 4 months after surgery. Papillary cystadenocarcinoma in the bitch could affect both ovaries and manifests with a rapid growth rate and clinical signs such as rapid exhaustion, abdominal enlargement and vulval discharge. Ovariohysterectomy is the treatment option.

    Cardiac papillary fibroelastomas (PFEs) are the most common tumors of the cardiac valves and the third most common cardiac tumor. They are usually detected accidentally on echocardiography, but have the potential to manifest with catastrophic embolic phenomena, resulting in stroke and myocardial infarction. Echocardiography is currently the preferred diagnostic modality, while magnetic resonance imaging and computed tomography are helpful in the differential diagnosis of cardiac tumors. The management of PFEs is empiric, as no large randomized trials have been conducted to support specific treatment guidelines. The treatment of choice for PFEs with high-risk features for peripheral embolization is surgical resection. Anticoagulation is recommended in patients who are poor surgical candidates or who refuse surgery, although its duration and intensity are debatable. This review summarizes current knowledge on the epidemiology, pathology, pathophysiology, clinical manifestations, diagnosis, and treatment of PFEs. It also highlights the need for large randomized clinical trials that would delineate more specific guidelines for managing PFEs with anticoagulation.

    Papillary muscle rupture is a rare, life-threatening post myocardial infarction mechanical complication. Without surgical intervention, prognosis is very poor. Clinicians need to recognize this complication early, as prompt therapy is crucial. We present a case of inferior ST elevation myocardial infarction complicated by posteromedial papillary muscle rupture resulting in severe acute mitral regurgitation (flail anterior mitral leaflet), acute pulmonary edema and cardiogenic shock. In our patient, a new mitral regurgitation murmur suggested this mechanical complication. Complete disruption of papillary muscle was visualized by transesophageal echocardiography. This case illustrates the importance of good physical examination for early diagnosis of papillary muscle rupture, so that life-saving treatment can be administered without delay.

    Full Text Available Papillary thyroid carcinoma (PTC is the most common epithelial thyroid tumor, accounting for more than 80% of all thyroid tumors. Recent advances in ultrasonographic screening and US-guided fine-needle aspiration biopsy (FNAB have facilitated the early detection and diagnosis of papillary thyroid carcinomas. In exceptionally rare cases, papillary thyroid tumors may assume enormous dimensions due to recurrent disease or the patient's negligence of the problem. We report an extremely rare case of a 72-year-old woman presented with a neglected giant exophytic papillary thyroid carcinoma with hemorrhagic ulcers. Computed tomography showed a mass measured 17×12 cm that caused a displacement of the trachea to the right side and reached the mediastinum. After bleeding management, patient was discharged. The patient was fully aware of her situation, but she denied any further therapeutic management.

    Incomplete surgical staging is a negative prognostic factor for patients with borderline ovarian tumours (BOT). However, little is known about the prognostic impact of each individual staging procedure. Clinical parameters of 950 patients with BOT (confirmed by central reference pathology) treated between 1998 and 2008 at 24 German AGO centres were analysed. In 559 patients with serous BOT and adequate ovarian surgery, further recommended staging procedures (omentectomy, peritoneal biopsies, cytology) were evaluated applying Cox regression models with respect to progression-free survival (PFS). For patients with one missing staging procedure, the hazard ratio (HR) for recurrence was 1.25 (95%-CI 0.66-2.39; P=0.497). This risk increased with each additional procedure skipped reaching statistical significance in case of two (HR 1.95; 95%-CI 1.06-3.58; P=0.031) and three missing steps (HR 2.37; 95%-CI 1.22-4.64; P=0.011). The most crucial procedure was omentectomy which retained a statistically significant impact on PFS in multiple analysis (HR 1.91; 95%-CI 1.15-3.19; P=0.013) adjusting for previously established prognostic factors as FIGO stage, tumour residuals, and fertility preservation. Individual surgical staging procedures contribute to the prognosis for patients with serous BOT. In this analysis, recurrence risk increased with each skipped surgical step. This should be considered when re-staging procedures following incomplete primary surgery are discussed.

    Full Text Available Fabio Mazzolani,1 Stefano Togni21Private Ophthalmology Practice, 2Indena SpA, Milan, ItalyBackground: The therapeutic effects of Meriva®, a curcumin-phospholipid (lecithin delivery system (formulated as Norflo® tablets, on visual acuity and retinal thickness in patients with acute and chronic central serous chorioretinopathy was previously investigated in a six-month open-label study.Methods: In this follow-up study, visual acuity was again assessed by ophthalmologic evaluation and retinal thickness by optical coherence tomography (OCT. Norflo tablets were administered twice daily to patients with central serous chorioretinopathy. The study group consisted of 12 patients (total 18 eyes who completed 12 months of follow-up. The primary endpoint was change in visual acuity before and after treatment with Norflo, and change in neuroretinal or retinal pigment epithelium detachment on OCT was the secondary endpoint.Results: After 12 months of therapy, no eyes showed further reduction in visual acuity, 39% showed stabilization, and 61% showed statistically significant improvement (P = 0.0001 by Student’s t-test and P = 0.0005 by Wilcoxon signed rank test. Ninety-five percent of eyes showed a reduction in neuroretinal or retinal pigment epithelium detachment and 5% showed stabilization. The difference in retinal thickness after 12 months was statistically significant (P = 0.0001 by Student’s t-test and P = 0.0004 by Wilcoxon signed rank test.Conclusion: These results, albeit preliminary, confirm our previous finding that this curcumin delivery system is effective in the management of central serous chorioretinopathy. When administered in a bioavailable formulation, curcumin is worth considering as a therapeutic agent for the management of inflammatory and degenerative eye conditions involving activation of retinal microglial cells.Keywords: curcumin, central serous chorioretinopathy, retinal pigment epithelium detachment, Norflo®, Meriva®

    Full Text Available ABSTRACT Acute lymphoblastic leukemia is a malignant hematopoietic neoplasia, which is rare in adults. Although ocular fundus alterations may be commonly observed in the course of the disease, such alterations are rarely the presenting signs of the disease. Here we describe the case of a patient with painless and progressive loss of visual acuity (right eye, 2/10; left eye, 3/10 developing over two weeks, accompanied by fever and cervical lymphadenopathy. Fundus examination showed bilateral macular serous detachment, which was confirmed by optical coherence tomography. Fluorescein angiography revealed hyperfluorescent pinpoints in the posterior poles. The limits of the macular detachment were revealed in the late phase of the angiogram. The results of blood count analysis triggered a thorough, systematic patient examination. The diagnosis of acute lymphoblastic leukemia B (CD10+ was established, and intensive systemic chemotherapy was immediately initiated. One year after the diagnosis, the patient remains in complete remission without any ophthalmologic alterations.

We present an atypical case of hypertensive chorioretinopathy with massive bilateral serous retinal detachment. Case Report: A 26-year-old male with a genitourinary malformation and secondary grade IV chronic kidney failure as well as high blood pressure complained of acute vision loss. Dilated fundus examination evidenced a bilateral serous retinal detachment with macular involvement. The patient was unresponsive to oral antihypertensive therapy and dialysis treatment. The serous retinal detachment progressively decreased after the restoration of dialysis and antihypertensive therapy. The final visual acuity was 0.50 in both eyes. Discussion: In cases of serous macular detachment, it is mandatory to rule out different systemic and ocular diseases. The presence of uncontrolled high blood pressure may produce aggressive bilateral retinal changes, thus hypertension must be under early and strict control in order to improve the visual outcomes.

    Full Text Available OBJECTIVES: The objective of this study was to evaluate the relationship between the treatment of Helicobacter pylori gastric infection and changes in best-corrected visual acuity and macular detachment in patients with chronic central serous chorioretinopathy. METHODS: Seventeen patients diagnosed with central serous chorioretinopathy were examined for gastric infection with Helicobacter pylori using the urease test and gastric biopsy. Helicobacter pylory-positive patients were treated with the appropriate medication. The response to therapy was monitored by evaluating the best-corrected visual acuity and optical coherence tomography. The data were analyzed using Student's t-test before and after treatment. RESULTS: Fourteen patients (15 eyes aged 30-56 years (mean 43.4 ± 8.3 years were positive for Helicobacter pylori. Most of the positive patients had gastric symptoms (78.5%; one had bilateral central serous chorioretinopathy. The mean baseline best-corrected visual acuity was 20/98 (logMAR = 0.53 ± 0.28. Three months after starting treatment with antibiotics, the serous detachment had resolved in 14 of 15 eyes, but two cases required laser treatment. The follow-up period ranged from 6 to 27 months. The mean final best-corrected visual acuity differed significantly from baseline. CONCLUSION: Our findings suggest that Helicobacter pylori infection may be present in many chronic central serous chorioretinopathy patients and that treatment for the infection may have a favorable effect on the outcome of chronic central serous chorioretinopathy. Due to the possibility of the spontaneous regression of chronic central serous chorioretinopathy and the high prevalence of the infection in the general population, prospective and masked clinical trials are necessary to confirm that treatment for Helicobacter pylori infection may benefit patients with chronic central serous chorioretinopathy.

    2018-03-01

    Full Text Available PURPOSE: Tumor-infiltrating lymphocytes (TILs have an established impact on the prognosis of high-grade serous ovarian carcinoma (HGSOC, however, their role in recurrent ovarian cancer is largely unknown. We therefore systematically investigated TIL densities and MHC class I and II (MHC1, 2 expression in the progression of HGSOC. EXPERIMENTAL DESIGN: CD3+, CD4+, CD8+ TILs and MHC1, 2 expression were evaluated by immunohistochemistry on tissue microarrays in 113 paired primary and recurrent HGSOC. TILs were quantified by image analysis. All patients had been included to the EU-funded OCTIPS FP7 project. RESULTS: CD3+, CD4+, CD8+ TILs and MHC1 and MHC2 expression showed significant correlations between primary and recurrent tumor levels (Spearman rho 0.427, 0.533, 0.361, 0.456, 0.526 respectively; P<.0001 each. Paired testing revealed higher CD4+ densities and MHC1 expression in recurrent tumors (Wilcoxon P=.034 and P=.018. There was also a shift towards higher CD3+ TILs levels in recurrent carcinomas when analyzing platinum-sensitive tumors only (Wilcoxon P=.026 and in pairs with recurrent tumor tissue from first relapse only (Wilcoxon P=.031. High MHC2 expression was the only parameter to be significantly linked to prolonged progression-free survival after first relapse (PFS2, log-rank P=.012. CONCLUSIONS: This is the first study that analyzed the development of TILs density and MHC expression in paired primary and recurrent HGSOC. The level of the antitumoral immune response in recurrent tumors was clearly dependent on the one in the primary tumor. Our data contribute to the understanding of temporal heterogeneity of HGSOC immune microenvironment and have implications for selection of samples for biomarker testing in the setting of immune-targeting therapeutics.

  1. Does multifocal papillary micro-carcinoma require radioiodine ablation?

    International Nuclear Information System (INIS)

    Punda, A.; Markovic, V.; Eterovic, D.

    2015-01-01

    Full text of publication follows. Background: the thyroid carcinomas smaller than 1 cm (micro-carcinomas) comprise a significant fraction of papillary carcinomas. Excluding clinical micro-carcinomas, which present as metastatic disease, the micro-carcinomas diagnosed by ultrasound/FNAC or incidentally have very good prognosis. However, whether or not these papillary micro-carcinomas require post-surgical radioiodine ablation remains a matter of debate. Hypothesis: multi-focality is present in majority of clinical papillary micro-carcinomas and this characteristic can be used to identify the subset of non-clinical micro-carcinomas with greater malignant potential. Methods: the data on types of differentiated thyroid carcinomas diagnosed in the period 2008-2011 in the University Hospital Split were collected. Results: there were 359 patients with thyroid carcinoma, 329 (92%) of which had papillary carcinoma. About 61% (202/329) of papillary carcinomas were micro-carcinomas; most of them were diagnosed by ultrasound/FNAC (134/202= 66%), the rest were incidentalomas (48/202=24%) and clinical micro carcinomas (20/202=10%). Sixty percent (12/20) of patients with clinical micro-carcinoma and 23 patients with non-clinical micro-carcinoma (23/182=13%) had multifocal disease. Conclusion: multifocal disease is a frequent characteristic of clinical papillary thyroid micro-carcinomas, suggesting that multi-focality presents an early stage of non-clinical micro-carcinomas with more aggressive behaviour. Thus multifocal, but not uni-focal papillary micro-carcinomas may require radioiodine ablation. (authors)

    The events leading to the most common and most lethal ovarian carcinoma - high grade serous carcinoma - have been poorly understood. However, the detailed pathologic study of asymptomatic women with germ-line BRCA 1 or BRCA2 (BCRA+) mutations has unearthed an early malignancy, serous tubal intraepithelial carcinomas (STIC), which has linked many peritoneal and ovarian serous carcinomas to the fimbria. The distinction between high-grade serous and endometrioid carcinomas continues to narrow, with shared alterations in expression of pTEN, PAX2 and p53. Moreover, the discovery of clonal alterations in p53 in benign tubal epithelium, - p53 signatures - has established a foundation for a serous cancer precursor in the fimbria. We have expanded this concept to include a generic secretory cell outgrowth (SCOUT) in the fallopian tube that is associated with altered PAX2 expression. As the repertoire of gene alterations is expanded and its link to serous carcinogenesis clarified, a cogent pathway to high-grade Mullerian carcinomas will emerge. This will challenge conventional thinking about ovarian carcinogenesis but will provide a new template for studies of ovarian cancer prevention.

    Full Text Available The aim of this retrospective, nationwide, matched cohort study was to investigate the association of serous retinal detachment with having end-stage renal disease (ESRD while on dialysis. The cohort study included 94,024 patients with ESRD on dialysis registered between January 2000 to December 2009 in the Taiwan National Health Insurance Research Database. An age- and sex-matched control group comprised 94,024 patients selected from the Taiwan Longitudinal Health Insurance Database 2000. Information for each patient was collected from the index date until December 2011. Twenty-seven ESRD patients and 11 controls developed serous retinal detachment (P < 0.001 during follow-up, demonstrating a significantly increased risk of serous retinal detachment in patients with ESRD on dialysis compared with controls (incidence rate ratio = 3.39, 95% confidence interval [CI] = 1.68-6.83. After adjustment for potential confounders, patients were 3.86 times more likely to develop serous retinal detachment than the full cohort (adjusted HR = 3.86, 95% CI = 1.15-12.96. In conclusion, patients with ESRD on dialysis demonstrate an increased risk of serous retinal detachment. Interdisciplinary collaboration between nephrologists and ophthalmologists is important to deal with serous retinal detachment in patients with ESRD on dialysis and prevent impairments of visual acuity.

    Full Text Available We would like to present an interesting case operated on in our department and discuss the international bibliography about this issue. We also present some interesting images of this case. Our material is composed from a 68-year-old woman treated by the authors. She presented with a small murmur in the auscultation while she was asymptomatic and then she diagnosed with a tumor on of the left coronary cusp of the aortic valve with the characteristics of papillary fibroelastoma. On the basis of the potential embolic risk either of the mass itself or of associated thrombus and the possibility of further enlargement, the patient although asymptomatic at the time of diagnosis was referred for elective surgical excision of the mass. She underwent on median sternotomy and through extracorporeal circulation the mass has been excised with the preservation of the well-functioning valve. Through this case, we would like to discuss the bibliography for the decision making in these cases. Hence, the aim of our study is that we have to keep in mind that this kind of friable mass may be the cause of embolism, stroke or coronary artery occlusion and must be excided in a conservative setting, sparing the aortic valve.

    Summary Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer. Here, we describe the genomic landscape of 496 PTCs. We observed a low frequency of somatic alterations (relative to other carcinomas) and extended the set of known PTC driver alterations to include EIF1AX, PPM1D and CHEK2 and diverse gene fusions. These discoveries reduced the fraction of PTC cases with unknown oncogenic driver from 25% to 3.5%. Combined analyses of genomic variants, gene expression, and methylation demonstrated that different driver groups lead to different pathologies with distinct signaling and differentiation characteristics. Similarly, we identified distinct molecular subgroups of BRAF-mutant tumors and multidimensional analyses highlighted a potential involvement of oncomiRs in less-differentiated subgroups. Our results propose a reclassification of thyroid cancers into molecular subtypes that better reflect their underlying signaling and differentiation properties, which has the potential to improve their pathological classification and better inform the management of the disease.

    Two hundred and twelve papillary and 40 follicular carcinomas were found in 3002 thyroid glands examined from 1931 to 1975 in four Laboratories of Pathology that fairly cover northern Portugal. There was a striking preponderance of women both in papillary (female:male = 6.9:1) and follicular carcinoma (5.7:1). Sex-specific frequency of malignancy was significantly greater in men (13.3%) than in women (8.8%). The overall papillary/follicular ratio was 5.3:1 and did not significantly change throughout the study period. Papillary/follicular ratio was not significantly greater in litoral (5.5:1) than in regions with a low iodine intake and a relatively high prevalence of goiter (3.5:1). It is advanced that this high relative frequency of papillary carcinoma in northern Portugal, even in goiter areas, may reflect the existence of a racial factor since there is not enough evidence to support the influence of dietary iodine, previous irradiation and concurrent thyroiditis.

    Objective: To assess the diagnostic value of contrast-enhanced 64-row CT scanning in deciding benign or malignant serous ovarian tumors. Methods: Fifty-eight cases of serous ovarian tumors proved pathologically were reviewed, including 25 malignant tumors, 25 benign, 8 borderline tumors. All patients underwent 64-row CT scanning, including plain scanning and contrast-enhance scanning. The tumors' shape, density, blood supply and enhancement features were evaluated. Results: Twenty-five cases of benign serous cystic adenoma were mostly unicameral, and showed a moderate mural enhancement only in 4 cases (16%) due to chronic pelvic infection and the others (21/25, 84%) had no of slight enhancement. Malignant tumors were cystic-solid mass with unclear margin, irregular shape and septa. Twenty-two cases of serous cystadenocarcinoma out of 25 cases (88%) appeared obvious enhancement and other 3 cases no enhancement. And 7 cases out of 8 (87.5%) borderlined serous cystadenomas showed different enhancement patterns. Conclusion: Benign ovarian serous neoplasms were mostly unicameral and no strong mural enhancement, suggesting a lack of blood supply. While, there were obvious enhancement in the ovarian serous cystadenocarcinoma and borderline serous cystadenoma with malignant potential. The 64-row CT is helpful for differentiating the nature of the serous ovarian neoplasm. (authors)

    Papillary proliferation of the endometrium is an unusual lesion that is composed of papillae with fibrovascular stromal cores covered with benign-appearing glandular epithelium. We studied the clinicopathological and immunohistochemical features of four cases of endometrial papillary proliferations. All patients were postmenopausal. Two lesions were incidental findings in hysterectomy specimens, and two lesions were detected in endometrial curettage specimens. Based on the degree of architectural complexity and extent of proliferation, we classified papillary proliferations histopathologically into "simple" or "complex" growth patterns. Three cases were classified as simple papillary proliferation, and one case was classified as complex papillary proliferation. Simple papillary proliferations were characterized by slender papillae with delicate stromal cores. In contrast, complex papillary proliferations had intracystic papillary projections and cellular clusters with frequent branching and occasional cytological atypia. All cases showed coexistent metaplastic epithelial changes, including mucinous metaplasia, eosinophilic cell change, and ciliated cell metaplasia. One patient with simple papillary proliferations had coexistent well-differentiated endometrioid carcinoma. One patient had subsequent hyperplasia without atypia, and another patient had subsequent atypical hyperplasia/endometrioid intraepithelial neoplasia; both patients underwent total hysterectomy within four months. Our observations are consistent with previous data demonstrating that endometrial papillary proliferations coexist with or develop into atypical hyperplasia/endometrioid intraepithelial neoplasia or endometrioid carcinoma. It is very important for pathologists to discriminate papillary proliferations from neoplastic lesions (including atypical hyperplasia/endometrioid intraepithelial neoplasia and well-differentiated endometrioid carcinoma) and benign mimickers (including papillary

    A 73-year-old man presented with a chief complaint of progressive left knee pain for two months. He had a history of total thyroidectomy and central lymph node dissection due to papillary thyroid carcinoma three months ago. MRI images revealed a solid mass in the left patella. A solid mass demonstrated low signal on T1 weighed image, and high signal on T2 weighed image. And whole body bone scan showed focal photon defect in same lesion of left patella. The histologic result of left knee lesion was adenocarcinoma, consistent with metastatic papillary thyroid carcinoma. Although patellar metastasis of papillary thyroid carcinoma is very rare, when knee pain and radiologic abnormality are noted, differential diagnosis of metastasis is necessary

    2017-08-01

    Intraductal papillary neoplasm of the bile duct (IPNB) is a rare variant of bile duct tumors, characterized by papillary growth within the bile duct lumen and is regarded as a biliary counterpart of intraductal papillary mucinous neoplasm (IPMN) of the pancreas. IPNBs are mainly found in patients from Far Eastern areas, where hepatolithiasis and clonorchiasis are endemic. The Western experience, however, remains limited. In this article, we report a 56-year-old man, referred to our hospital because of deranged liver function tests. Further imaging modalities showed a cystic lesion of 9 cm diameter, arising from the left hepatic duct. Inlying was a heterogeneous, lobulated mass. The patient underwent a left hemihepatectomy and adjuvant chemotherapy. Despite recent advanced technologies, diagnosis of IPNB is still challenging, especially in western countries due to its rarity. Early identification and resection of lesions, even in asymptomatic or minimally symptomatic patients, are however important prognostic factors.

    Hashimoto's thyroiditis (HT) seems to have favourable prognostic impact on papillary thyroid cancer (PTC), but data were obtained analysing all disease stages. Given that HT-related microenvironment involves solely the thyroid, we aimed to assess the relationship between HT, as detected through pathological assessment, and outcome in intrathyroidal PTC. This was a multicentre, retrospective, observational study including 301 PTC with no evidence of extrathyroidal disease. Primary study endpoint was the rate of clinical remission. Auxiliary endpoint was recurrence-free survival (RFS). HT was detected in 42.5% of the cohort and was associated to female gender, smaller tumour size, lower rate of aggressive PTC variants and less frequent post-surgery radio-iodine administration. HT showed relationship with significantly higher rate of clinical remission ( P  < 0.001, OR 4, 95% CI 1.78-8.94). PTCs with concomitant HT had significantly longer RFS, as compared with non-HT tumours ( P  = 0.004). After adjustment for other parameters affecting disease outcome at univariate analysis (age at diagnosis, histology, tumour size and multifocality), prognostic effect of HT remained significant ( P  = 0.006, OR 3.28, 95% CI 1.39-7.72). To verify whether HT could optimise the identification of PTCs with unfavourable outcome, we assessed the accuracy of 'non-HT status' as negative prognostic marker, demonstrating poor capability of identifying patients not maintaining clinical remission until final follow-up (probability of no clinical remission in PTCs without HT: 21.05%, 95% CI 15.20-27.93). In conclusion, our data show that HT represents an independent prognostic parameter in intrathyroidal PTC, but cannot improve prognostic specificity. © 2017 Society for Endocrinology.

Much still remains unknown about the molecular mechanisms of thyroid cancer. Studies have found that some certain relationship between ARAP3 and human cancer. However, the role of ARAP3 in thyroid cancer has not been well explained. This study aimed to investigate the role of ARAP3 gene in papillary thyroid carcinoma. Methods: Whole exon sequence and whole genome sequence of primary papillary thyroid carcinoma (PTC samples and matched adjacent normal thyroid tissue samples were performed and then bioinformatics analysis was carried out. PTC cell lines (TPC1, BCPAP, and KTC-1 with transfection of small interfering RNA were used to investigate the functions of ARAP3 gene, including cell proliferation assay, colony formation assay, migration assay, and invasion assay. Results: Using next-generation sequence and bioinformatics analysis, we found ARAP3 genes may play an important role in thyroid cancer. Downregulation of ARAP3 significantly suppressed PTC cell lines (TPC1, BCPAP, and KTC-1, cell proliferation, colony formation, migration, and invasion. Conclusion: This study indicated that ARAP3 genes have important biological implications and may act as a potentially drugable target in PTC.

    The prognostic factors of uterine serous carcinoma (USC) vary among studies, and there is no report of Chinese USC patients. The aim of this study was to investigate the clinicopathological characteristics and prognostic factors in Chinese patients with USC. Patients with USC from 13 authoritative university hospitals in China and treated between 2004 and 2014 were retrospectively reviewed. Three-year disease-free survival rate (DFSR), cumulative recurrence, and cumulative mortality were estimated by Kaplan-Meier analyses and log-rank tests. Multivariate Cox regression analysis was used to model the association of potential prognostic factors with clinical outcomes. Data of a total of 241 patients were reviewed. The median follow-up was 26 months (range, 1-128 months). Median age was 60 years (range, 39-84 years), and 58.0% had stages I-II disease. The 3-year DFSR and cumulative recurrence were 46.8% and 27.7%. Advanced stage (III and IV) (P = 0.004), myometrial invasion (P = 0.001), adnexal involvement (P USC. Prospective studies are needed to confirm these results.

    Full Text Available There are several mimickers of choroidal melanoma. We report a patient with recent family stress who developed blurred vision to 20/50 OD and was found to have unilateral central serous chorioretinopathy and a coincidental choroidal nevus. After 1 year without resolution of the subretinal fluid, the patient was referred for our opinion. On examination, visual acuity was 20/50 in the right eye and 20/20 in the left eye. The left eye was normal. Evaluation of the right eye showed a small, pigmented submacular choroidal lesion measuring 4 mm Χ 3 mm. Ultrasonography documented an isoechoic mass measuring 1.71 mm in thickness. Optical coherence tomography showed subretinal fluid with shaggy photoreceptors and hyper-reflective material within the subretinal fluid, likely indicative of lipofuscin within macrophages. Autofluorescence revealed orange pigment overlying the lesion. These features were strongly suggestive of small choroidal melanoma with five risk factors for tumor growth. Treatment with Iodine-125 plaque brachytherapy was performed on the patient. The readers should keep in mind that choroidal melanoma can manifest as a tiny choroidal mass with related multimodal imaging features of subretinal fluid and orange pigment.

    Tumors of the epididymis are very rare. They are benign tumors in 75 per cent of the cases. Papillary cystadenoma represents 4-9 per cent of epididymal benign tumors. Often associated with the syndrome of von Hippel Lindau and infertility, histologically it can be confused with metastatic renal cell carcinoma. We report two cases of papillary cystadenoma located in the head of the right epididymis, with no concomitance with the syndrome of von Hippel Lindau, cured by the removal of the neoplastic nodule. There was no recidivation, in confirmation of the neoplastic benignity.

    Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) is a new terminology proposed for encapsulated follicular variant of papillary thyroid carcinoma (EFVPTC). Recently, thyroid cancer incidence has increased dramatically, without affecting related mortality rate. This increase is widely attributed to the intensified surveillance leading to a substantial increase in the diagnosis of small classic papillary thyroid cancers and EFVPTCs. Recent studies emphasize the indolent behavior of the EFVPTC. Recently, there has been a reclassification of EFVPTC as NIFTP, a benign entity. The financial and emotional burden of 'cancer' diagnosis and treatment can be significant. This review recapitulates the literature supporting the reclassification of EFVPTC as NIFTP, a benign entity, and reviews standardized diagnostic criteria for EFVPTC. The information highlighted in this review will affect surgical decision making and may promote the offering of hemithyroidectomy over a total thyroidectomy to some patients with 'indeterminate' cytopathological category; postoperative radioiodine ablation will not be required for NIFTP patients.

    Full Text Available Abstract Background To report two cases of atypical vitelliform macular dystrophy misdiagnosed as chronic central serous chorioretinopathy. Case presentation Two patients with incidentally discovered abnormalities of the retina without specific symptoms were referred to our hospital for consultation. Bilateral macula atrophic lesions were observed and optical coherence tomography revealed serous retinal detachment in the macula. Fluorescein angiography showed multiple leakages around the central hypofluorescent area and indocyanine green angiography showed partially dilated choroidal vessels. Fundus autofluorescence (FAF showed a decreasing pattern of autofluorescence in the subretinal fluid area, and increasing autofluorescence at the border of the serous retinal detachment. Both patients were diagnosed with chronic central serous chorioretinopathy. Photodynamic therapy and intravitreal bevacizumab injection were administered for engorged choroidal vessels during follow-up, but neither patient showed improvement in symptoms or ophthalmologic findings. Based on re-evaluation by fundus photography, optical coherence tomography, fluorescein angiography, and comparison of the results of FAF with the first visit, vitelliform macular dystrophy was suspected and a definite diagnosis was made by electrooculography and genetic testing. Conclusion In patients with continuous serous retinal detachment without response to photodynamic therapy or intravitreal bevacizumab injection, careful fundus exam and FAF can be used to diagnose atypical vitelliform macular dystrophy.

    Papillary craniopharyngioma is an intracranial tumor that results in high levels of morbidity. We recently demonstrated that the vast majority of these tumors harbor the oncogenic BRAF V600E mutation. The pathologic diagnosis of papillary craniopharyngioma can now be confirmed using mutation specific immunohistochemistry and targeted genetic testing. Treatment with targeted agents is now also a possibility in select situations. We recently reported a patient with a multiply recurrent papillary craniopharyngioma in whom targeting both BRAF and MEK resulted in a dramatic therapeutic response with a marked anti-tumor immune response. This work shows that activation of the MAPK pathway is the likely principal oncogenic driver of these tumors. We will now investigate the efficacy of this approach in a multicenter phase II clinical trial. Post-treatment resection samples will be monitored for the emergence of resistance mechanisms. Further advances in the non-invasive diagnosis of papillary craniopharyngioma by radiologic criteria and by cell-free DNA testing could someday allow neo-adjuvant therapy for this disease in select patient populations.

    Full Text Available ABSTRACT Purpose: To ınvestigate frequency of fibromyalgia syndrome (FMS among patients with central serous chorioretinopathy (CSCR. Methods: The study included 83 patients with CSCR and 201 age- and sex-matched healthy controls; the mean age was 47.5 ± 11.3 years in the CSCR group (18 women; 21.7% and 47.2 ± 11.2 years in the control group (44 women; 21.9%. All participants were assessed for FMS based on 2010 American College of Rheumatology diagnostic criteria and for depression and anxiety with the Beck Anxiety Inventory (BAI and Beck Depression Inventory (BDI. Results: FMS was diagnosed in 35 patients (42.2% from the CSCR group and in 21 individuals (10.4% from the control group (p<0.001. It was found in 77.77% of the women (14/18 and 32.3% of the men (21/65 in the CSCR group and in 22.7% of the women (10/44 and 7.0% of the men (11/157 in the control group. Familial stress, BDI and BAI scores were higher in the patients with FMS than in those without. When independent risk factors were evaluated by logistic regression analysis, it was found that only the presence of familial stress was a significant risk factor for FMS. Conclusions: Patients with CSCR should be assessed for the presence of FMS, and this should be taken into consideration when developing a treatment plan. Further studies with a larger sample size are needed to clarify the relationship between FMS and CSCR.

    The lack of proven screening tools for early detection and the high mortality of ovarian serous carcinoma (OSC), particularly high grade, have focused attention on identifying putative precursor lesions with distinct morphological and molecular characteristics. The finding of occult invasive and intraepithelial fallopian tube carcinomas in prophylactically removed specimens from asymptomatic high-risk BRCA 1/2-mutation carriers supports the notion of an origin for OSC in the fallopian tube. The intraepithelial carcinomas have been referred to as serous intraepithelial carcinomas (STICs) but our own findings (unpublished data) and recent reports have drawn attention to a spectrum of changes that fall short of STICs that we have designated serous tubal intraepithelial lesions (STILs).

    2013-01-01

    To report a case of recurrent central serous chorioretinopathy (CSC) after performing peripheral laser photocoagulation for retinal degenerations. A 44-year-old woman with ocular history of CSC presented to the emergency room of our department complaining of heavy photopsia due to retinal tuft and lattice degenerations, and underwent laser photocoagulation to prevent retinal detachment. Two days after laser treatment, the visual acuity dropped, and optical coherence tomography scan showed the onset of CSC. The serous detachment completely resolved in 20 days with no therapy. A new CSC episode occurred in the same eye after another analogous laser treatment and, similarly, quickly resolved spontaneously. We reviewed the literature and discuss the possibility that laser-induced inflammation could rouse an inflammatory cascade mediated by proinflammatory cytokines and PAI-1, leading to the exacerbation of retinal serous detachment in susceptible patients.

    Full Text Available Ovarian pregnancy is a rare form of extra uterine pregnancy. Serous cyst adenoma is a benign variant of epithelial cell tumors of ovary. The coexistence of a cyst adenoma with an ovarian pregnancy in the same ovary is extremely rare. Some studies suggested that infertility or ovulation-inducing drugs can be involved in increased risk of ovarian tumors and ovarian pregnancies. A 28-year-old infertile woman presented with a ruptured ovarian pregnancy following ovulation induction with metformin. She had a concurrent benign serous cyst adenoma in the same ovary. Resection of both ovarian pregnancy and tumoral mass were performed. The ovary was preserved. Removal of gestational tissue and preservation of the involved ovary are the best options for management of ovarian pregnancy in young patient. Although there is an association between infertility/ovulation inducting medications and ovarian gestation, their connections with serous cyst adenoma are undetermined.

    Toll-like receptors (TLRs) are transmembrane proteins expressed on the surface of ovarian cancer (OC) and immune cells. Identifying the specific roles of the TLR-mediated signaling pathways in OC cells is important to guide new treatments. Because immunotherapies have emerged as the adjuvant treatment for patients with OC, we investigated the effect of a promising immunotherapeutic strategy based on protein aggregate magnesium-ammonium phospholinoleate-palmitoleate anhydride (P-MAPA) combined with cisplatin (CIS) on the TLR2 and TLR4 signaling pathways via myeloid differentiation factor 88 (MyD88) and TLR-associated activator of interferon (TRIF) in an in vivo model of OC. Tumors were chemically induced by a single injection of 100 μg of 7,12-dimethylbenz(a)anthracene (DMBA) directly under the left ovarian bursa in Fischer 344 rats. After the rats developed serous papillary OC, they were given P-MAPA, CIS or the combination P-MAPA+CIS as therapies. To understand the effects of the treatments, we assessed the tumor size, histopathology, and the TLR2- and TLR4-mediated inflammatory responses. Although CIS therapy was more effective than P-MAPA in reducing the tumor size, P-MAPA immunotherapy significantly increased the expressions of TLR2 and TLR4. More importantly, the combination of P-MAPA with CIS showed a greater survival rate compared to CIS alone, and exhibited a significant reduction in tumor volume compared to P-MAPA alone. The combination therapy also promoted the increase in the levels of the following OC-related proteins: TLR4, MyD88, TRIF, inhibitor of phosphorylated NF-kB alpha (p-IkBα), and nuclear factor kappa B (NF-kB p65) in both cytoplasmic and nuclear sites. While P-MAPA had no apparent effect on tumor necrosis factor alpha (TNF-α) and interleukin (IL)-6, it seems to increase interferon-γ (IFN-γ), which may induce the Thelper (Th1)-mediated immune response. Collectively, our results suggest that P-MAPA immunotherapy combined with cisplatin

    We report the imaging features of a case of a temporal bone meningioma extending into the middle ear cavity and clinically presenting as a serous otitis media. Temporal bone meningioma extending in the mastoid or the middle ear cavity, however, is very rare. In case of unexplained or therapy-resistant serous otitis media and a nasopharyngeal tumor being ruled out, a temporal bone computed tomography (CT) should be performed. If CT findings are suggestive of a temporal bone meningioma, a magnetic resonance imaging (MRI) examination with gadolinium will confirm diagnosis and show the exact extension of the lesion

    Full Text Available To report subretinal migration of indocyanine green dye (ICG and subsequent retinal pigment epithelial (RPE atrophy during macular surgery for serous macular detachment. A 65-year-old woman presented with residual epiretinal membrane and serous detachment of the macula following vitreoretinal surgery for epiretinal membrane. She underwent resurgery with ICG-assisted internal limiting membrane peeling and intraocular tamponade. Intraoperatively a large area of subretinal ICG was seen with subsequent RPE mottling and atrophy of the macula in the area involved during follow-up. This case demonstrates that subretinal migration of ICG is possible and can be toxic to RPE.

    Chronic central serous chorioretinopathy (CSCR) is a progressive chorioretinopathy with widespread atrophic RPE abnormalities and serous retinal detachments (SRDs) present for 6 months or longer. We report a case of CSCR in a 38-year-old patient with Pigment Dispersion Syndrome (PDS). In the presented case of CSCR, the chronic course of the disease may in part be associated with an underlying generalized degenerative dysfunction of the pigmented cells of the eye on grounds of PDS. We suggest that a chronic course of disease may be suspected in the setting of CSCR with concurrent RPE pathology, such as what is found in PDS.

    Ovarian cancers present a mild clinical course when diagnosed early but an aggressive pathway when diagnosed in the peri- and postmenopausal periods. However, the predictability of tumor progression is stochastic and is difficult to predict. In the present study, we hypothesized to examine the key pathways that are dysregulated to promote epithelial-mesenchymal transition in serous ovarian carcinoma. Examination of these steps would help to identify ascitic fluid with cells poised for metastasis or otherwise. We focused on examining the Akt2 expression, mainly because of its report as being overamplified in the aggressive variants of ovarian cancer, as well as TGFbeta-sensitivity of Akt2 that forms the key basis for metastasis initiation of most kinds of carcinoma. We obtained primary ovarian carcinoma samples as well as ascitic fluid and distantly metastatic ovarian carcinoma to examine the expression of Akt2. The results of the study demonstrated that in malignant exfoliated ovarian cancer cells, Smad4 expression was tremendously increased in the nuclei, suggesting nuclear translocation of Smad, which thereafter may have activated ZEB2, and thereafter genomically affected the expression of E-cadherin, myosin II, and vimentin, key components for initiating and sustaining metastasis. All of these may have been stimulated by increased cellular expression of Akt2 in metastatic variants of the serous ovarian carcinoma. The reliance on Akt2 and TGF beta signaling may also potentiate the case for Akt inhibitors or small molecule inhibitors of TGFbeta signaling like doxycycline as adjunct chemotherapy in serous ovarian carcinoma, especially the metastatic variants.

    Objective To evaluate the safety and survival in women treated with adjuvant pelvic radiation “sandwiched” between six cycles of paclitaxel and carboplatin chemotherapy with completely resected UPSC. Methods Surgically staged women with UPSC (FIGO stage 1-4) and no visible residual disease were enrolled. Treatment involved paclitaxel (175 mg/m2) and carboplatin (AUC=6.0-7.5) every 21 days for 3 doses, followed by radiation therapy (RT), followed by an additional 3 cycles of paclitaxel and carboplatin (AUC=5-6). Survival analysis, using Kaplan-Meier methods, was performed on patients who completed at least 3 cycles of chemotherapy and RT. Results A total of 81 patients were enrolled, of which 72 patients completed the first 3 cycles of chemotherapy followed by prescribed RT. Median age was 67 years (range: 43–82 years). 59/72 (82%) had disease confined to the uterus and 13/72 (18%) had completely resected extra-uterine disease (stage 3&4). 65 (83%) completed the protocol. Overall PFS and OS for combined stage 1&2 patients was 65.5±3.6 months and 76.5±4.3 months, respectively. PFS and OS for combined stage 3&4 patients was 25.8±3.0 and 35.9±5.3 months, respectively. Three-year % survival probability for stage 1&2 patients was 84% and for stage 3&4 patients was 50%. Of the 435 chemotherapy cycles administered, there were 11(2.5%) G3/G4 non-hematologic toxicities. 26(6.0%) cycles had dose reductions and 37(8.5%) had dose delays. Conclusions Compared to prior studies of single modality adjuvant therapy, RT “sandwiched” between paclitaxel and carboplatin chemotherapy is well-tolerated and highly efficacious in women with completely resected UPSC.

    Papillary and reticular fibroblasts have different effects on keratinocyte proliferation and differentiation. The aim of this study was to investigate whether these effects are caused by differential secretion of soluble factors or by differential generation of extracellular matrix from papillary and reticular fibroblasts. To study the effect of soluble factors, keratinocyte monolayer cultures were grown in papillary or reticular fibroblast-conditioned medium. To study the effect of extracellular matrix, keratinocytes were grown on papillary or reticular-derived matrix. Conditioned medium from papillary or reticular fibroblasts did not differentially affect keratinocyte viability or epidermal development. However, keratinocyte viability was increased when grown on matrix derived from papillary, compared with reticular, fibroblasts. In addition, the longevity of the epidermis was increased when cultured on papillary fibroblast-derived matrix skin equivalents compared with reticular-derived matrix skin equivalents. The findings indicate that the matrix secreted by papillary and reticular fibroblasts is the main causal factor to account for the differences in keratinocyte growth and viability observed in our study. Differences in response to soluble factors between both populations were less significant. Matrix components specific to the papillary dermis may account for the preferential growth of keratinocytes on papillary dermis.

    The identification of a marker for early progression of preinvasive lesions into invasive pelvic high-grade serous carcinoma (HGSC) may provide novel handles for innovative screening and prevention strategies. The interplay between cancer cells and the extracellular matrix (ECM) is one of the main principles in cancer development and growth, but has been largely neglected in preinvasive lesions. This is the first study addressing the involvement of the ECM in the "step-by-step" transition of normal fallopian tube epithelium into preinvasive lesions, and eventually the progression of preinvasive lesions into invasive HGSC. The expression of highly sulfated chondroitin sulfate (CS-E), a characteristic glycosaminoglycan of the cancer-associated ECM, was assessed by immunohistochemistry in a large cohort of precursor lesions of the full spectrum of HGSC development, including 97 serous tubal intraepithelial carcinomas (STICs), 27 serous tubal intraepithelial lesions, and 24 p53 signatures. In addition, the immunological reactivity in the microenvironment was evaluated. Increased stromal expression of highly sulfated CS-E was observed in 3.7%, 57.7%, and 90.6% of serous tubal intraepithelial lesions, STICs, and invasive HGSCs, respectively (P STIC, P STIC and paired HGSC was demonstrated. Intense stromal CS-E expression in STIC was significantly associated with an immune infiltrate (P < 0.001). Our study showed that increased stromal CS-E expression is related to the degree of the tubal epithelium abnormality. Specific alterations in the ECM (ie, CS-E expression) occur early in pelvic HGSC development and may represent a novel biomarker of early cancer progression, useful for the identification of novel clinical strategies.

  15. ALDH1-high ovarian cancer stem-like cells can be isolated from serous and clear cell adenocarcinoma cells, and ALDH1 high expression is associated with poor prognosis.

    Directory of Open Access Journals (Sweden)

    Takafumi Kuroda

    Full Text Available Cancer stem-like cells (CSCs/cancer-initiating cells (CICs are defined as a small population of cancer cells that have high tumorigenicity. Furthermore, CSCs/CICs are resistant to several cancer therapies, and CSCs/CICs are therefore thought to be responsible for cancer recurrence after treatment and distant metastasis. In epithelial ovarian cancer (EOC cases, disease recurrence after chemotherapy is frequently observed, suggesting ovarian CSCs/CICs are involved. There are four major histological subtypes in EOC, and serous adenocarcinoma and clear cell adenocarcinoma are high-grade malignancies. We therefore analyzed ovarian CSCs/CICs from ovarian carcinoma cell lines (serous adenocarcinoma and clear cell adenocarcinoma and primary ovarian cancer cells in this study. We isolated ovarian CSCs/CICs as an aldehyde dehydrogenase 1 high (ALDH1(high population from 6 EOC cell lines (3 serous adenocarcinomas and 3 clear cell adenocarcinomas by the ALDEFLUOR assay. ALDH1(high cells showed greater sphere-forming ability, higher tumorigenicity and greater invasive capability, indicating that ovarian CSCs/CICs are enriched in ALDH1(high cells. ALDH1(high cells could also be isolated from 8 of 11 primary ovarian carcinoma samples. Immunohistochemical staining revealed that higher ALDH1 expression levels in ovary cancer cases are related to poorer prognosis in both serous adenocarcinoma cases and clear cell adenocarcinoma cases. Taken together, the results indicate that ALDH1 is a marker for ovarian CSCs/CICs and that the expression level of ALDH1 might be a novel biomarker for prediction of poor prognosis.

    On the basis of results of our previous studies and the findings of other scholars, the most common histologic type of false-positive diagnosis with strain elastography (SE) was papilloma. The objectives of our study were to evaluate whether SE could contribute to conventional ultrasound differentiation between benign and malignant papillary lesions and between papillary lesions and other common benign breast lesions. Data on 89 papillary lesions at our hospital, including 74 benign and 15 malignant papillary lesions, were included in our study. In addition, 198 non-papillary benign tumors were selected as the control group, including 126 fibroadenomas and 72 cases of fibrocystic mastopathy. All patients gave written informed consent. All patients with breast lesions underwent conventional ultrasound and SE examination. Breast Imaging Recording and Data System (BI-RADS) category and SE score were compared with respect to sensitivity, specificity and accuracy in differentiating between benign and malignant papillary lesions. We then explored the possibility of using BI-RADS combined with SE to differentiate papillary lesions from non-papillary benign tumors. For differentiating between benign and malignant papillary lesions, the area under the receiver operating characteristic curve (AUC) of BI-RADS was 0.568, whereas the AUC values of SE score, strain ratio and BI-RADS combined with SE were 0.517, 0.584 and 0.509, respectively (p > 0.05). For differentiating between papillary lesions and non-papillary benign lesions, the AUC of BI-RADS combined with SE was 0.835, which was higher than the values for BI-RADS (0.775) and SE (SE score: 0.648, strain ratio: 0.661) (p breast papillary lesions from non-papillary benign lesions.

    Background Central serous chorioretinopathy (CSC) is characterized by serous detachment of the neural retina with dysfunction of the choroid and retinal pigment epithelium (RPE). The effects on the retina are usually self limited, although some people are left with irreversible vision loss due to progressive and permanent photoreceptor damage or RPE atrophy. There have been a variety of interventions used in CSC, including, but not limited to, laser treatment, photodynamic therapy (PDT), and intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF) agents. However, it is not known whether these or other treatments offer significant advantages over observation or other interventions. At present there is no evidence-based consensus on the management of CSC. Due in large part to the propensity for CSC to resolve spontaneously or to follow a waxing and waning course, the most common initial approach to treatment is observation. It remains unclear whether this is the best approach with regard to safety and efficacy. Objectives To compare the relative effectiveness of interventions for central serous chorioretinopathy. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2015, Issue 9), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to February 2014), EMBASE (January 1980 to October 2015), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en).

    In the past several decades, the concept of serous ovarian carcinoma has been revised repeatedly. However, the exact pathogenesis remains controversial. The most popular current concept is origin from the epithelium of the fimbriated ends of the fallopian tubes. The objective of our study was to evaluate the characteristic clinical and morphologic features of serous tubal intraepithelial carcinoma (STIC) and associated invasive carcinomas. One hundred sixteen consecutive cases of STIC seen from 2007 to 2011 were included in this study. High-grade serous carcinoma (HGSC) with or without a mixed component was identified in 107 cases (92.2%), non-HGSC in 5 cases, and STICs without invasive carcinoma in 4 cases. Using conventional criteria, HGSCs were classified as fallopian tube in origin in 65 cases (60.7%), as ovarian in 30 (28.0%), as peritoneal in 9 (8.4%), and as endometrial in 3 (2.8%). Among the 107 cases with HGSCs, most STICs (86; 80%) were present unilaterally, whereas invasive tumors more commonly involved the ovaries bilaterally (79%; 84 cases). These findings support the hypothesis that STIC acts as a precursor lesion for most fallopian tube, ovarian, and peritoneal HGSCs, but not for endometrial HGSC. Copyright © 2013 Elsevier Inc.

    Full Text Available Objectives: To investigate the epidemiology and frequency of serous macular detachment (SMD in patients diagnosed with diabetic macular edema (DME. Materials and Methods: Hundred and forty-three eyes of 104 patients with DME were examined retrospectively. According to the results of OCT, the patients were separated into two groups; patients diagnosed with SMD and DME (group 1 and patients diagnosed with DME (group 2. They were assessed based on demographic characteristics, average age, duration of diabetes mellitus (DM, hypertension (HT history, best-corrected visual acuity, and diabetic retinopathy stages. Results: The average age of the patients was 61±8.7 years. Forty-three patients (41.3% were female and 61 patients (58.7% were male. Fifty-four of 104 patients (51.9% had DME with SMD. 21 (38.8% patients had bilateral SMD. In group 1, 31 patients were male (57.4% and 23 patients were female (42.6%. In group 2, 30 (60% patients were male and 20 (40% patients were female. In group 1, average age was 60.2±9.6 and the average duration of DM was 12.2±7.0 years, whereas the average age was 61.9±7.6 and the average duration of DM was 14.06±6.8 years in group 2. Forty-two patients in group 1 (77.8% and 30 patients (60% in group 2 had history of HT. Before the treatment, the average best-corrected visual acuity was found to be 0.30±0.24 in group 1 and 0.32±0.25 in group 2. Conclusion: Today, it is thought that diabetic maculopathy is the leading cause of SMD and it is a determining factor of treatment applications. In our study, we aimed at investigating the frequency of SMD in DME and the risk factors for the development of SMD. Although there were some differences between the factors, only the history of HT was found statistically higher in patients with SMD (p=0.04. (Turk J Ophthalmol 2015; 45: 92-96

    Objective: To evaluate the relationship between the CT imaging features and pathologic findings of papillary thyroid carcinoma (PTC) and papillary thyroid microcarcinoma (PTMC), as well as the CT appearances of Non-papillary thyroid carcinoma(N-PTC). Methods: CT features of 229 PTC, 42 PTMC and 36 N-PTC patients with 264, 57 and 41 lesions respectively were analyzed retrospectively, and comparison was made with the pathologic findings. All data were analyzed by X 2 test. Results: (1) Of PTC lesions, 25.4% (67/264)of the lesions and 2.9% (24/828) of metastatic lymph nodes showed cystic changes. Cyst formation with intracystic high density papillary-like nodules were found in 31.3% (21/67)of the PTC lesions and 37.5% (9/24) of metastatic lymph nodes. The histologic appearances of these tumors demonstrated fibrous tissue forming the wall of cyst, and papillary-like tumor tissue. (2) 75.2% (112/149) of PTC and 33.3% (5/15) of PTMC showed multiple small granular and fine calcifications, and there was statiscally significant difference between the two (P 0.05). However, the degree of enhancement in PTC lesions were less than that of N-PTC, 36.6% (94/257) of PTC and 54.1% (20/37)of N-PTC lesions showed significant enhancement, and there was statistically significant difference (P<0.05). 75.1% of PTC (172/229) and 52.8% of (19/36)N-PTC had cervical lymph node metastases, with a propensity fbr PTC to have more VI region metastatic lymph nodes, 80.8% (139/172)vs 57.9% (11/19), which was statistically significant (both P<0.05). (4)Distant metastases to bone or lung were rare, but N-PTC (5/36) were more likely to produce distant metastases than PTC (5/229), and there was statistically significant difference (P<0.01). Conclusion Multiple, small granular and fine calcifications were found more frequently in PTC than PTMC. Compared with N-PTC, the papillary-like mural nodules of PTC showed less enhancement on post-contrast CT and cervical lymph node metastases were more

    The differentiation of benign mesothelial cells from malignant tumor cells, primary, or metastatic, in serous effusions based on cytomorphologic features alone can be problematic. Purpose: This study was conducted to evaluate the utility of p53 and ki67 imrminocytochemical markers in differentiating benign from malignant tumor cells in serous effusions. Patients and methods: Archival Papanicolaou-stained smears of 91 pleura and peritoneal effusions were retrieved from Cytology Unit, Pathology Department, NCI, Cairo University between 2008 and 2010. Forty-one cases were positive for malignant cells and 50 cases were benign based on cytomorphologic features. Cases having doubt were excluded from the study. The slides were de stained and subjected to immunocytochemical staining for p53 and ki67. Histologic sections of colonic carcinoma and tonsillar tissue were used as positive control for p53 and ki67, respectively. Smears having > 5% positively stained nuclei for p53 were taken as positive and labeling index 10% of ki67 was considered positive. Frequencies of the individual immunocytochemical stains; p53 and ki67, in benign and malignant effusion as well as the combination of both stains were calculated. Results: p53 immunostaining showed nuclear positivity in 31 out of 41 malignant effusions (75.6%) and in 3 out of 50 benign effusions (6%), p < 0.005. p53 had 75.6% sensitivity, 94% specificity, 91.2% PPV, and 82.5% NPV. ki67 immunostaining was positive in 30 out of 41 malignant effusions (73.2%) and in 17 out of 50 benign effusions (34%), p < 0.05. ki67 had 73.2% sensitivity, 66% specificity, 63.8% PPV, and 75% NPV. Cases were then analyzed for combined immuno profile of p3 and ki67. Among the 24 cases that coexpressed both antigens, 22 cases (91.7%) were malignant. Thirty two out of 34 cases (94.1%) that showed negative results for both antigens were benign. For the cases that showed p53 immunostaining only, 9 out of 10 cases (90%) were malignant. Fifteen out of

    Full Text Available The molecular biology and cellular origins of mixed type endometrial carcinomas (MT-ECs are poorly understood, and a Type II component of 10 percent or less may confer poorer prognoses.We studied 10 cases of MT-EC (containing endometrioid and serous differentiation, 5 pure low-grade endometrioid adenocarcinoma (EAC and 5 pure uterine serous carcinoma (USC. Endometrioid and serous components of the MT-ECs were macrodissected and the expression of 60 candidate genes compared between MT-EC, pure USC and pure EAC. We found that four genes were differentially expressed when MT-ECs were compared to pure low-grade EAC: CDKN2A (P = 0.006, H19 (P = 0.010, HOMER2 (P = 0.009 and TNNT1 (P = 0.006. Also while we found that even though MT-ECs closely resembled the molecular profiles of pure USCs, they also exhibit lower expression of PAX8 compared to all pure cases combined (P = 0.035.Our data suggest that MT-EC exhibits the closest molecular and epidemiological similarities to pure USC and supports clinical observations that suggest patients with MT-EC should receive the same treatment as patients with pure serous carcinoma. Novel specific markers of MT-EC could be of diagnostic utility and could represent novel therapeutic targets in the future.

    The malignant potential of serous ovarian tumors, the most common ovarian tumor subtype, varies from benign to low malignant potential (LMP) tumors to frankly invasive cancers. Given the uncertainty about the relationship between these different forms, we compared their patterns of gene expression. Expression profiling was carried out on samples of 7 benign, 7 LMP and 28 invasive (moderate and poorly differentiated) serous tumors and four whole normal ovaries using oligonucleotide microarrays representing over 21,000 genes. We identified 311 transcripts that distinguished invasive from benign tumors, and 20 transcripts that were significantly differentially expressed between invasive and LMP tumors at p < 0.01 (with multiple testing correction). Five genes that were differentially expressed between invasive and either benign or normal tissues were validated by real time PCR in an independent panel of 46 serous tumors (4 benign, 7 LMP, 35 invasive). Overexpression of SLPI and WNT7A and down-regulation of C6orf31, PDGFRA and GLTSCR2 were measured in invasive and LMP compared with benign and normal tissues. Over-expression of WNT7A in an ovarian cancer cell line led to increased migration and invasive capacity. These results highlight several genes that may play an important role across the spectrum of serous ovarian tumorigenesis

    Full Text Available Abstract Background Serous adenomas represent 1-2% of pancreatic neoplasms and typically are asymptomatic not requiring any treatment and simple observation is the option of choice. Although, they carry a realistic risk of malignancy despite the general view that they never become malignant. We report a case, which, according to our best knowledge is the 27th case reported in the literature. Methods We reviewed the literature by performing a search in Pub Med and Medline. Results A 86-year old patient known to have a serous cystadenoma of the pancreas treated conservatively through a close clinical and radiological follow up which was unattended for 4 years ending up to our emergency department suffering an acute abdomen. Exploratory laparotomy revealed a perforated prepyloric ulcer which was treated accordingly. Patient died some weeks later due to severe medical co morbidities. Conclusion Serous cystic neoplasms of the pancreas carry a realistic risk of malignancy despite the general view that they never become malignant. In our opinion the treatment strategy of serous cystic neoplasms of the pancreas should be aggressive even in cases of remote metastases since prognosis of the disease is satisfactory

    Ovarian cancer is the most common cause of death among women with gynecologic cancer. We examined molecular profiles of fibroblasts from normal ovary and high-grade serous ovarian tumors to identify novel therapeutic targets involved in tumor progression. We identified 2,300 genes that are significantly differentially expressed in tumor-associated fibroblasts. Fibroblast expression of one of these genes, connective tissue growth factor (CTGF), was confirmed by immunohistochemistry. CTGF protein expression in ovarian tumor fibroblasts significantly correlated with gene expression levels. CTGF is a secreted component of the tumor microenvironment and is being pursued as a therapeutic target in pancreatic cancer. We examined its effect in in vitro and ex vivo ovarian cancer models, and examined associations between CTGF expression and clinico-pathologic characteristics in patients. CTGF promotes migration and peritoneal adhesion of ovarian cancer cells. These effects are abrogated by FG-3019, a human monoclonal antibody against CTGF, currently under clinical investigation as a therapeutic agent. Immunohistochemical analyses of high-grade serous ovarian tumors reveal that the highest level of tumor stromal CTGF expression was correlated with the poorest prognosis. Our findings identify CTGF as a promoter of peritoneal adhesion, likely to mediate metastasis, and a potential therapeutic target in high-grade serous ovarian cancer. These results warrant further studies into the therapeutic efficacy of FG-3019 in high-grade serous ovarian cancer.

    Full Text Available Papillary carcinoma is a prominent malignancy originating from follicular cells. This disease generally shows an indolent character, but patients demonstrating certain clinicopathological features have a dire prognosis. At present, Western countries adopted almost routine total thyroidectomy with radioactive iodine (RAI ablation, while limited thyroidectomy with extensive prophylactic lymph node dissection has traditionally been performed for most patients in Japan. Recently, accurate evaluation of carcinoma stage can be performed on preoperative imaging studies, especially on ultrasonography. It is therefore important to treat papillary carcinoma patients depending on clinicopathological features rather than in a stereotyped fashion. In this paper, appropriate extension of thyroidectomy and lymph node dissection is discussed based on Western and recently published Japanese guidelines and the experience in Kuma Hospital.

    We report a case of suprasellar papillary craniopharyngioma metastatic to the temporoparietal region 2 years after its initial resection. The literature documents examples of craniopharyngioma recurrences along the surgical tract, as well as remote ipsi- and contralateral metastases via cerebrospinal fluid seeding. Ours is the second report of a craniopharyngioma of papillary type to exhibit metastatic behavior. The tumor spread opposite the side of craniotomy. Although a rare occurrence, it confirms the limited capacity of histologically benign craniopharyngiomas to undergo meningeal seeding, likely the result of surgical manipulation. Immunohistochemical demonstration of increased microvascular density and vascular endothelial growth factor expression, as well as a high vascular endothelial growth receptor (VEGFR2) signal by in situ hybridization, suggests that tumor vascularity facilitated angiogenesis and may have been involved in the establishment and growth of the metastatic deposit.

    2013-01-01

    Full Text Available Intraductal papillary mucinous neoplasm (IPMN of the pancreas is an intraductal mucin-producing epithelial neoplasm that arises from the main and/or branched pancreatic duct. It usually presents as cystic lesion of pancreas. There are well known differential diagnosis of cystic pancreatic lesion. Pancreatic cystic neoplasms are detected at an increasing frequency due to an increased use of abdominal imaging. The diagnosis and treatment of intraductal papillary mucinous tumors (IPMN of the pancreas has evolved over the past decade. IPMN represents a spectrum of disease, ranging from benign to malignant lesions, making the early detection and characterization of these lesions important. Definitive management is surgical resection for appropriate candidates, as benign lesions harbor malignant potential. IPMN has a prognosis, which is different from adenocarcinoma of the pancreas. We report a case of a 58-year-old male with intraductal papillary neoplasm involving main duct and side branches presenting to us with clinical symptoms of chronic pancreatitis with obstructive jaundice and cholangitis treated surgically.

    Full Text Available Metastasis to the thyroid gland is very rare. Recently, we experienced a case of thyroid metastasis from breast cancer accompanying a papillary thyroid. A 51-year-old female patient presented with a palpated lymph node on her left lateral neck. The patient had undergone a left modified radical mastectomy followed by chemotherapy and hormonal therapy 12 years prior. Ultrasonography of the neck revealed a malignant looking nodule at the left thyroid lobe, measuring 0.9 × 0.9 cm, and several cystic nodules at the right thyroid lobe. Ultrasonography of the neck additionally revealed a malignant looking lymph node at the right level VI. Fine-needle aspiration of the left thyroid lobe resulted in a diagnosis of papillary thyroid carcinoma and that of the right level VI in Hurthle cell lesion. The patient had a total thyroidectomy with selective dissection of the left neck node. Pathologic assessment of the specimen revealed metastatic carcinoma from the breast carcinoma and papillary thyroid carcinoma. Although the thyroid gland is highly vascularized, metastasis of malignant tumors to the thyroid is relatively rare and detection of metastasis shows a low frequency. So a careful evaluation of thyroid tumor should be considered in a patient with a history of other malignancy.

    The present study was performed for elucidating the associations between the morphology of the papillary muscles (PMs) and sudden cardiac arrest (SCA). We retrospectively reviewed history, laboratory data, electrocardiography, echocardiography, coronary angiography, and cardiac CT/MRI for 190 patients with SCA. The prevalence of accessory PMs and PM hypertrophy in patients with SCA of unknown cause was compared with that in patients with SCA of known causes and 98 age- and sex-matched patients without SCA. An accessory PM was defined as a PM with origins separated from the anterolateral and posteromedial PMs, or a PM that branched into two or three bellies at the base of the anterolateral or posteromedial PM. PM hypertrophy was defined as at least one of the two PMs having a diameter of ≥1.1cm. In 49 patients (age 49.9±15.9years; 38 men) the cause of SCA was unknown, whereas 141 (age 54.2±16.6years; 121 men) had a known cause. The prevalence of accessory PMs was significantly higher in the unknown-cause group than in the known-cause group (24.5% and 7.8%, respectively; p=0.002) or the no-SCA group (7.1%, p=0.003). The same was true for PM hypertrophy (unknown-cause 12.2%, known-cause 2.1%, p=0.010; no SCA group 1.0%, p=0.006). By logistic regression, accessory PM and PM hypertrophy were independently associated with sudden cardiac arrest of unknown cause. An accessory PM and PM hypertrophy are associated with SCA of unknown cause. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    The presence or absence of myoepithelial cells (ME) has been considered as an important feature in the differential diagnosis of benign and malignant papillary lesions of the breast. We evaluated the distribution of myoepithelial cells in formalin-fixed paraffin-embedded tissue sections of 25 papillomas and 18 papillary carcinomas by ABC immunoperoxidase technique with antibodies to muscle actin (HHF-35) and high molecular weight (HMW) keratin (clone 34BE12, cytokeratins 1, 5, 10, and 14; reacting preferentially with ME cells) and an antiserum to S-100 protein. Also included in the study were eight cases of micropapillary ductal carcinoma in situ (DCIS) having a few fibrovascular cores and five peripheral papillomas with accompanying ductal carcinoma in situ or atypical hyperplasia. The antibodies to muscle actin were sensitive and relatively specific for ME cells of the breast and uniformly labeled ME cells in all 25 papillomas. ME cells were absent or extremely sparse in papillary carcinomas. They were present focally in some of the fibrovascular cores of the micropapillary DCIS, and a mixed pattern was observed in peripheral papillomas with areas of carcinoma. HMW keratin was variably expressed in ME cells in most cases with positive internal controls and was present in several normal ductal and papilloma epithelial cells but not in epithelial cells of papillary carcinomas. HMW keratin, although less specific for ME cells, was a useful adjunct because of its reactivity with ME cells as well as hyperplastic epithelial cells in papillomas, which resulted in a combined positive reaction.(ABSTRACT TRUNCATED AT 250 WORDS)

    Purpose: The typically benign, but occasionally rapidly fatal clinical course of papillary thyroid cancer has raised the need for individual survival probability estimation, to tailor the treatment strategy exclusively to a given patient. Materials and methods: A retrospective study was performed on 400 papillary thyroid cancer patients with a median follow-up time of 7.1 years to establish a clinical database for uni- and multivariate analysis of the prognostic factors related to survival (Kaplan-Meier product limit method and Cox regression). For a more precise prognosis estimation, the effect of the most important clinical events were then investigated on the basis of a Markov renewal model. The basic concept of this approach is that each patient has an individual disease course which (besides the initial clinical categories) is affected by special events, e.g. internal covariates (local/regional/distant relapses). On the supposition that these events and the cause-specific death are influenced by the same biological processes, the parameters of transient survival probability characterizing the speed of the course of the disease for each clinical event and their sequence were determined. The individual survival curves for each patient were calculated by using these parameters and the independent significant clinical variables selected from multivariate studies, summation of which resulted in a mean cause-specific survival function valid for the entire group. On the basis of this Markov model, prediction of the cause-specific survival probability is possible for extrastudy cases, if it is supposed that the clinical events occur within new patients in the same manner and with the similar probability as within the study population. Results: The patient's age, a distant metastasis at presentation, the extent of the surgical intervention, the primary tumor size and extent (pT), the external irradiation dosage and the degree of TSH suppression proved to be

    ABSTRACT: Ovarian cancer accounts for 5% of all cancers among women and causes more deaths than any other female genital tract cancer. The majority (85-90%) of ovarian cancers is epithelial in origin and arises typically in postmenopa usal patients. An ovarian serous cystadenocarcinoma forms the malignant end of ovari an serous tumours. It is the most common malignant ovarian tumor and is derived from glandul ar epithelium, in which cystic accumulations of ret...

Psychophysiological factors may trigger or maintain CSCR, though, surprisingly, the association between CSCR and anxiety has yet to be studied. The aims of the present study were threefold: to determine whether 1 Iranian patients with CSCR have higher scores for anxiety, 2 anxiety is lower, if CSCR has been experienced twice, and whether 3 anxiety scores differ between sexes.Methods: A total of 30 patients with CSCR and 30 healthy age- and sex-matched controls took part in the study. A brief face-to-face interview was conducted covering demographic variables and history and occurrence of CSCR and assessing anxiety.Results: Compared to healthy controls, anxiety was significantly higher in both first-time and second-time CSCR patients. In CSCR patients, anxiety scores did not differ between sexes.Conclusion: Higher anxiety scores were observed in Iranian patients with CSCR, irrespective of whether this was the first or second occurrence of CSCR. This suggests there is no psychological adaptation in terms of reduced anxiety among patients with repeated CSCR. Keywords: idiopathic central

    Full Text Available Background: Papillary thyroid carcinoma is typical by regional lymph nodes metastases. Therefore we decided to analyse associated risk factors. Objective: In this retrospective study we focused on the incidence of metastatic involvement of the central compartment’s lymph nodes correlated with age, size of the primary tumour, infiltration of thyroid gland capsule, positive lymphangioinvasion in order to assess risk factors. Method: We analysed group of 156 patients with papillary carcinoma, who have undergone total thyroidectomy and bilateral elective central compartment neck dissection. We evaluated the occurrence of metastases, size, infiltration and lymphangioinvasion based on definitive histology of the whole group and separately for subgroups of patients under and over 45 years. Result: We found metastatic involvement in 88 (56.4% patients. When comparing the subgroups of patients under (73 patients and over 45 years (83 patients, we found metastases in 56 vs. 32 (76.7% vs. 38.6% patients. In the subgroup of younger patients we found significant higher incidence of metastases compared with the group of over 45 years, P < 0.001 (P = 0.000027. We found significant higher incidence of metastases in patients with positive capsule infiltration in the whole group, P < 0.001 (P = 0.00049; in the subgroup of under 45 years, P < 0.001 (P = 0.00091 and in patients with positive lymphangioinvasion in the whole group, P < 0.01 (P = 0.00177; in the subgroup of over 45 years, P < 0.001 (P = 0.0002. In patients with metastases we found tumour size ≥1cm more frequently in all groups. Conclusion: We recorded higher incidence of regional metastases in patients under 45 years, positive capsule infiltration, lymphangioinvasion. Age under 45 years itself does not correlate with less aggressive disease, to the contrary some of other analysed risk factors correlate with more aggressive disease.

    This study was designed to compare the ultrasonographic features of papillary thyroid carcinoma with and without Hashimoto's thyroiditis. This retrospective study included 190 patients with papillary thyroid carcinoma which was proven by neck surgery. The difference in the ultrasonographic findings between papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis were calculated statistically. Hashimoto's thyroiditis was diagnosed in 61 of 190 patients following neck surgery. The incidence of coexisting papillary thyroid carcinoma with Hashimoto's thyroiditis was significantly higher in women (p=0.0026). In addition, the frequency of macrocalcification in patients with Hashimoto's thyroiditis was also significantly higher (p=0.0009). Conversely,other ultrasonographic findings including the shape, margin, echogenicity and calcifications, for patients with papillary thyroid carcinoma with Hashimoto's thyroiditis and papillary thyroid carcinoma without Hashimoto's thyroiditis, were not statistically significant. We also found that patients with Hashimoto's thyroiditis who showed no calcification on ultrasonography tended not to detect the papillary carcinoma at a higher frequency. On ultrasonography, macrocalcifications occurred more frequently in patients with Hashimoto's thyroiditis than those without Hashimoto's thyroiditis. Malignant thyroid nodules without calcifications in patients with Hashimoto's thyroiditis more often could not be detected. Therefore, it is important carefully examine patients with Hashimoto's thyroiditis

    Full Text Available Malignant transformation of endometriosis has been extensively described in the literature. However, extragonadal endometrioid adenocarcinoma, either de novo or arising from malignant transformation of endometriosis, is rare. The present case report describes a patient with endometrioid adenocarcinoma on the serous surface of the small intestine. A 25- year-old female with no history of endometriosis was referred to our hospital with an intrapelvic tumor. An internal examination, ultrasound, and magnetic resonance imaging revealed a round mass approximately 80 mm in diameter; however, identification of the affected organ was difficult. Because we could not rule out malignancy based on the non-specific radiologic findings, laparotomy was performed. A mass with ileal adhesions was detected intraoperatively. In addition, the uterus and bilateral adnexa appeared normal. The tumor was resected with part of the ileum. Histopathology confirmed a diagnosis of endometrioid adenocarcinoma originating from the serous surface of the small intestine.

    Objective: To investigate the CT spectral imaging features of pancreatic serous oligocystic adenoma and mucinous cystic neoplasms and to assess the value of spectral CT in differentiating between pancreatic serous oligocystic adenoma and mucinous cystic neoplasms. Methods: From Feb. 2010 to Dec. 2010, 27 patients with cystic neoplasms of the pancreas (group one with 15 serous oligocystic adenomas and group two with 12 mucinous cystic neoplasms) underwent dual-phase CT spectral imaging followed by surgery. Quantitative values (age, tumor size, CT value change as function of photon energy, effective-Z, iodine-water concentration, and calcium-water concentration) were compared with independent samples t test and Mann-Whitney test and non-quantitative parameters (gender, symptom, and tumor location) were compared with Chi-square test (Fisher exact). The parameters with significant differences between two groups were analyzed further and the performance of multiple parameters for joint differential diagnosis was evaluated with discriminant analysis. Results: Compared to patients with mucinous cystic neoplasms, patients with serous oligocystic adenoma had younger age, lower frequency of being symptomatic and smaller tumor size. The CT values on 40 keV to 60 keV (with 10 keV increment) in late arterial phase [(36±13) HU vs. (62±23) HU, (26±8) HU vs. (40±15) HU, and (19±6) HU vs. (27±10) HU respectively] and 40 keV to 50 keV (with 10 keV increment) in portal venous phase [(43±14) HU vs. (61±25) HU and (30±10) HU vs. (40±16) HU respectively], effective-Z (late arterial phase 7.80± 0.16 vs. 8.05±0.21, and portal venous phase 7.87±0.15 vs 8.02±0.22), concentration of calcium (water) [late arterial phase (5±3) g/L vs. (11±4) g/L, t=-3.836, P=0.001 and portal venous phase (7±3) g/L vs. (10±5) g/L, t=-2.071, P=0.049] and iodine (water) [late arterial phase (0.38±0.24) g/L vs. (0.78±0.32) g/L, t=-3.755, P=0.001 and portal venous phase (0.48± 0.24) g/L vs. (0

    Serous cystadenoma of the pancreas and mucinous tumors of the vermiform appendix are rare. To our knowledge, the simultaneous occurrence of these two tumors has not been reported. Here, we report an adult female who presented with signs and symptoms of appendicitis. A preoperative CT scan confirmed the findings of appendicitis and also showed an incidental large mass in the head of the pancreas. The patient underwent uneventful appendectomy. Her pathology revealed an acutely inflamed appendix with a benign mucinous cystadenoma at the tip. Several months after her recovery, a Whipple procedure was performed. Pathologic examination showed a 5x5 cm serous cystadenoma of the head of the pancreas without evidence of malignancy. Two years later, the patient is alive and well without evidence of tumor recurrence. Cystadenomas of the pancreas and appendix are unusual and their simultaneous occurrence is a rare event.

    Full Text Available The article presents features of clinical course and composition of cerebrospinal liquid in cases of purulent and serous meningitis depending on the age of the patients and the disease etiology. 40 children with bacterial purulent meningitis of meningococcal, hemophilic and unknown aetiology and 40 children with serous meningitis predominantly of enteroviral etiology were examined. The differences in duration and intensity of clinical symptoms, total protein concentration, and liquor cytosis were detected. The highest liquor indicators were revealed in the case of hemophilic meningitis in children of early age and in the case of meningococcal meningitis in children over seven years old. This fact can be explained by various pathogenic features of the causative agent and different compensatory reactions in children of different age.

    Thyroid malignant tumors are rarely associated with hyperfunctioning thyroid. The incidence of this co-incidence is highly variable. Here we report a rare case of papillary thyroid cancer associated with hyperthyroidism with brief literature review. A 40-year-old male, presented with palpitation, excess sweating and weight loss for one month duration. There was asymmetrical swelling of the neck, more on right side, mobile. Free T3: 11.09pmol/L, free T4: 34.41pmol/L, TFT: less than 0.005mIU/ml, Neck ultrasound showed features of background thyroiditis. Left lobe contained 9×7×5mm nodule with irregular outline and multiple dots of calcification, other nodules are of the same features. Under ultrasound guide, fine needle aspiration cytology showed features of papillary carcinoma. After preparation, total thyrodectomy done and the result of histopathological examination confirmed papillary thyroid carcinoma. The patient was put on 0.2mg thyroxine daily. Literature review has showed an increasing number of papers reporting the association of high level of thyroid function tests and thyroid malignancy. The cause of high level of TH in thyroid malignancy is thought to be due to an active mutation of the gene of TH receptor. Niepomniszcze and colleagues found that a combination of TSH receptor mutations and Ki-RAS was the main etiological factor for hyperfunction of the thyroid malignancy. Although the coexistence of them is rare, thyroid malignancy should be put in the differential diagnosis of hyperthyroid goiter. Copyright © 2016 The Authors. Published by Elsevier Ltd..

    The study aim to identify novel molecular subtypes of ovarian cancer by gene expression profiling with linkage to clinical and pathologic features. Microarray gene expression profiling was done on 285 serous and endometrioid tumors of the ovary, peritoneum, and fallopian tube. K-means clustering was applied to identify robust molecular subtypes. Statistical analysis identified differentially expressed genes, pathways, and gene ontologies. Laser capture microdissection, pathology review, and immunohistochemistry validated the array-based findings. Patient survival within k-means groups was evaluated using Cox proportional hazards models. Class prediction validated k-means groups in an independent dataset. A semisupervised survival analysis of the array data was used to compare against unsupervised clustering results. Optimal clustering of array data identified six molecular subtypes. Two subtypes represented predominantly serous low malignant potential and low-grade endometrioid subtypes, respectively. The remaining four subtypes represented higher grade and advanced stage cancers of serous and endometrioid morphology. A novel subtype of high-grade serous cancers reflected a mesenchymal cell type, characterized by overexpression of N-cadherin and P-cadherin and low expression of differentiation markers, including CA125 and MUC1. A poor prognosis subtype was defined by a reactive stroma gene expression signature, correlating with extensive desmoplasia in such samples. A similar poor prognosis signature could be found using a semisupervised analysis. Each subtype displayed distinct levels and patterns of immune cell infiltration. Class prediction identified similar subtypes in an independent ovarian dataset with similar prognostic trends. Gene expression profiling identified molecular subtypes of ovarian cancer of biological and clinical importance.

    2016-01-01

    Papillary lesions of the breast include a broad spectrum of lesions, ranging from benign papilloma, papilloma with atypical ductal hyperplasia (ADH) or ductal carcinoma in situ (DCIS) to papillary carcinoma. The accurate diagnosis of mammary papillary lesions is a challenge for pathologists, owing to the overlapping features among these lesions. In this review, some of the diagnostic criteria of papillary lesions are discussed, with special emphasis on some key morphological features, namely fibrovascular cores, epithelial proliferation in a solid pattern, intraductal papilloma complicated by ADH or DCIS, and invasion and its mimics. The roles of immunohistochemistry, and the interpretation of myoepithelial cell markers, hormone receptors, and high molecular weight cytokeratin, are addressed. Finally, novel biomarkers and genetic aberrations in papillary lesions are summarized. © 2015 John Wiley & Sons Ltd.

    We report an extremely rare case of papillary thyroid microcarcinoma (PTMC) in the thyroid pyramidal lobe (TPL). A 48-year-old woman underwent ultrasound-guided fine-needle aspiration for a small thyroid nodule in the right lobe in local clinic, and it revealed a malignant cytology. On preoperative ultrasonography for tumor staging in our hospital, another small suspiciously malignant hypoechoic nodule was detected in the left TPL. Total thyroidectomy and central nodal dissection were performed. Histopathology confirmed PTMCs in the left TPL and both thyroid lobes. Ultrasonography for TPL should be required for complete evaluation of possible multifocality of thyroid malignancy.

    After giving the essential physico-chemical properties of the colloids, the author considers the biological role of these substances and, in connection with their transport by the blood, their capture by elements of the reticula-endothelial system. A summary is given of present knowledge concerning the role of serous proteins in the transport of substances, particularly that of radio-active colloidal gold. The blood fractions which can take part in colloidal gold transport are the red blood corpuscles, the leukocytes and histiocytic elements as well as the plasma. The radioactive distribution in these various fractions is obtained by autoradiography of blood sediments. After showing the importance of the role of the plasma in radioactive particle transport, the author, describes the attempts made to detect a possible of colloidal gold 198 on the various serous proteins using various methods of separation. The ''in vitro'' and ''in vivo'' bonds between colloidal gold-198 particles and either the serous proteins or healthy specimens or the effusion liquids of pathological origin in man, or due to an experimental inflammation with carregenin in the rat, have been studied. The bonding appears to be effective because of the protective macromolecular layer formed by the gelatine. The different positions of the colloidal grains on the electrophoregram can only be explained by their different physico-chemical characteristics. Gold in the ionic form, on the other hand, is combined only with the albumen is the amount metal present does not exceed a certain value. (author) [fr

    Full Text Available Objective: To report chronic central serous choroidopathy with severe visual loss in hyperopic microphthalmic identical twins. Methods: The index patient was first examined in 1994, at age 31, and has been followed up closely for 17 years. He had repeated fluorescein and indocyanine green angiograms, OCT, ultrasound biometry, and recently also autofluorescence and EDI OCT. His twin brother was first examined in 2010, at age 47, and had a similar extensive exploration. Results: The index patient had a mean refractive error of +6 D OU and VA was 20/32++ in the RE and 20/200 in the LE in 1994. Vision slowly went down to 20/800+ in the RE and 20/600 in the LE in 2011. His twin brother has a mean refractive error of +6 D OU and VA 20/400 OU. Both have a short axial length of the eye, a thick choroid with dilated vessels, and central serous choroidopathy with cystic degeneration of the macula and retina in the posterior pole. Conclusions: We add to the reported complications of microphthalmos, chronic central serous choroidopathy.

    Idiopathic central serous chorioretinopathy (CSCR) is a relatively common ophthalmic disorder characterized by the development of a serous detachment of the sensory retina. Psychophysiological factors may trigger or maintain CSCR, though, surprisingly, the association between CSCR and anxiety has yet to be studied. The aims of the present study were threefold: to determine whether 1) Iranian patients with CSCR have higher scores for anxiety, 2) anxiety is lower, if CSCR has been experienced twice, and whether 3) anxiety scores differ between sexes. A total of 30 patients with CSCR and 30 healthy age-and sex-matched controls took part in the study. A brief face-to-face interview was conducted covering demographic variables and history and occurrence of CSCR and assessing anxiety. Compared to healthy controls, anxiety was significantly higher in both first-time and second-time CSCR patients. In CSCR patients, anxiety scores did not differ between sexes. Higher anxiety scores were observed in Iranian patients with CSCR, irrespective of whether this was the first or second occurrence of CSCR. This suggests there is no psychological adaptation in terms of reduced anxiety among patients with repeated CSCR.

    Papillary muscle plays an important role in stabilizing the position of the tricuspid valve. Several pathologies can result in anatomical and functional abnormalities of the papillary muscles. The aim of the study is to deliberate the morphometry of papillary muscles in tricuspid valve and to analyze with the eminent research works previously done. The study was carried out in 52 formalin-fixed adult apparently normal cadaveric hearts belonging to either sex obtained from the Department of Anatomy. These hearts were dissected carefully to open the right ventricle and to expose the papillary muscles. Different morphological features of papillary muscles were noted, and measurements were taken. The classical picture of three papillary muscles existed in 23.07% of the specimens. Anterior papillary muscle was in all hearts, but posterior and septal muscle was off in 15.38% and 55.76%, respectively. Double and triple papillary muscles were seen too. Anterior and posterior muscle appeared predominantly flat-top and arose from the middle third (mostly), while septal muscle was chiefly conical and originated basically from the upper third of the ventricular wall. Chordopapillary relationship with tricuspid valve leaflets was beyond conventional. Mean length and breadth of anterior muscle were 2.19±0.59 cm and 0.76±0.26 cm, those of posterior muscle were 1.39±0.63 cm and 0.67±0.43 cm, and those of septal papillary muscle were 0.95±0.38 cm and 0.59±0.09 cm. Detailed knowledge of normal and variable anatomy of papillary muscles is not only necessary for better understanding of tricuspid pathologies but also valuable for successful newer surgical approaches in cardiac treatment.

    Fabricio Furtado Vieira

    Full Text Available Abstract Background: Hyperthyroidism is currently recognized to affect the cardiovascular system, leading to a series of molecular and functional changes. However, little is known about the functional influence of hyperthyroidism in the regulation of cytoplasmic calcium and on the sodium/calcium exchanger (NCX in the cardiac muscle. Objectives: To evaluate the functional changes in papillary muscles isolated from animals with induced hyperthyroidism. Methods: We divided 36 Wistar rats into a group of controls and another of animals with hyperthyroidism induced by intraperitoneal T3 injection. We measured in the animals' papillary muscles the maximum contraction force, speed of contraction (+df/dt and relaxation (-df/dt, contraction and relaxation time, contraction force at different concentrations of extracellular sodium, post-rest potentiation (PRP, and contraction force induced by caffeine. Results: In hyperthyroid animals, we observed decreased PRP at all rest times (p < 0.05, increased +df/dt and -df/dt (p < 0.001, low positive inotropic response to decreased concentration of extracellular sodium (p < 0.001, reduction of the maximum force in caffeine-induced contraction (p < 0.003, and decreased total contraction time (p < 0.001. The maximal contraction force did not differ significantly between groups (p = 0.973. Conclusion: We hypothesize that the changes observed are likely due to a decrease in calcium content in the sarcoplasmic reticulum, caused by calcium leakage, decreased expression of NCX, and increased expression of a-MHC and SERCA2.

    A 6-year old patient presented with an intra and suprasellar cystic lesion accompanied with impairment of the hypothalamic-pituitary axis and partial hypopituitarism. The most likely cause of sellar lesions in this age group are adamantinomatous craniopharyngioma (adaCP) or Rathke´s cleft cysts (RCCs). AdaCP are characterized by CTNNB1 mutations accompanied with aberrant nuclear beta-catenin expression. RCC show neither nuclear beta-catenin expression nor BRAF mutation. The latter is a hallmark of papillary craniopharyngiomas (papCP) that exhibit remarkable histological similarity with metaplasia of RCC. Diagnosis of the patient was elucidated by CTNNB1 and BRAF mutation screening, utilizing different approaches, as well as histological examination of markers, e.g., beta-catenin, claudin-1, EpCAM and the mutated BRAFV600E protein, which are known to be differentially expressed in sellar lesions. The case presented reveals extraordinary aspects for two reasons. Firstly, the lesion appeared clinically, on MRI, intraoperatively and histologically as RCC with prominent squamous metaplasia, but showing an expression pattern of markers also found in papCP, whilst exhibiting a hitherto undescribed BRAF V 600 E mutation. This important result documents a supposable transition of RCC metaplasia into a papillary craniopharyngioma (papCP). Secondly, this intriguing case shows unexpectedly that although papCP usually occurs almost exclusively in adults, it can also arise in childhood.

    To determine the frequency of tuberculous cervical lymphadenopathy mimicking metastasis from papillary thyroid cancer. Study Design: Case series. Place and Duration of Study: Surgical Unit-I, Ward-3 of Jinnah Postgraduate Medical Centre, Karachi, from March 2005 to March 2010. Methodology: All patients above 12 years of age of either gender diagnosed on investigations as papillary thyroid cancer (PTC) were included in the study. Ultrasound and fine needle aspiration cytology (FNAC), neck of solitary thyroid nodules (STN) and cervical lymph nodes were done. Total thyroidectomy and excision biopsy of cervical lymph nodes was performed, histopathological results were recorded and patients were managed accordingly. Results: A total of 55 patients had PTC and 25 had cervical lymphadenopathy. Eighteen patients of PTC with cervical lymphadenopathy were diagnosed after investigations as cases of tuberculous cervical lymphadenopathy (TCL) initially considered as metastasis from PTC; 5 patients had metastasis from PTC. Two patients proved to be of reactive hyperplasia which initially showed tuberculous cervical lymphadenopathy on FNAC. So 80% patients of cervical lymphadenopathy with PTC were due to benign disease and 20% had metastasis in lymph node due to PTC. Conclusion: PTC with cervical lymphadenopathy due to co-existent tuberculosis is common. Metastasis from PTC in lymph nodes were less common than tuberculous lymphodenitis in this study. Tuberculosis should be considered before deciding for neck dissection in cases of PTC. (author)

    Papillary lesions of the breast range from benign to atypical to malignant. Although papillomas without frank cancer are benign, their management remains controversial. When a core needle biopsy of a lesion yields a diagnosis of intraductal papilloma with atypia, excision is generally recommended to rule out a concurrent malignant neoplasm. For intraductal papillomas without atypia, however, recommendations for excision versus observation are variable. The aims of this study are to evaluate the rate of concurrent malignancies for intraductal papilloma diagnosed on core needle biopsy and to assess the long-term risk of developing cancer after the diagnosis of a papillary lesion. This single institution retrospective study analyzed 259 patients that were diagnosed with intraductal papilloma (IDP) by core needle biopsy from 1995 to 2010. Patients were grouped by initial diagnosis into three groups (papilloma without atypia, papilloma with atypia, and papilloma with atypical duct hyperplasia or atypical lobular hyperplasia (ADH/ALH) and followed up for long-term outcomes. After a core needle biopsy showing IDP with atypia or IDP + ADH/ALH, surgical excision yielded a diagnosis of concomitant invasive or ductal in situ cancer in greater that 30% of cases. For intraductal papilloma without atypia, the likelihood of cancer was much lower. Moreover, even with excision, the finding of intraductal papilloma with atypia carries a significant risk of developing cancer long-term, and such patients should be followed carefully and perhaps should be considered for chemoprevention. © 2017 Wiley Periodicals, Inc.

    Since the first description of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas in the eighties, their identification has dramatically increased in the last decades, hand to hand with the improvements in diagnostic imaging and sampling techniques for the study of pancreatic diseases. However, the heterogeneity of IPMNs and their malignant potential make difficult the management of these lesions. The objective of this review is to identify the molecular characteristics of IPMNs in order to recognize potential markers for the discrimination of more aggressive IPMNs requiring surgical resection from benign IPMNs that could be observed. We briefly summarize recent research findings on the genetics and epigenetics of intraductal papillary mucinous neoplasms, identifying some genes, molecular mechanisms and cellular signaling pathways correlated to the pathogenesis of IPMNs and their progression to malignancy. The knowledge of molecular biology of IPMNs has impressively developed over the last few years. A great amount of genes functioning as oncogenes or tumor suppressor genes have been identified, in pancreatic juice or in blood or in the samples from the pancreatic resections, but further researches are required to use these informations for clinical intent, in order to better define the natural history of these diseases and to improve their management.

    The incidence of thyroid cancers is increasing worldwide. Some somatic oncogene mutations (BRAF, NRAS, HRAS, KRAS) as well as gene translocations (RET/PTC, PAX8/PPAR-gamma) have been associated with the development of thyroid cancer. In our study, we analyzed these genetic alterations in 394 thyroid tissue samples (197 papillary carcinomas and 197 healthy). The somatic mutations and translocations were detected by Light Cycler melting method and Real-Time Polymerase Chain Reaction techniques, respectively. In tumorous samples, 86 BRAF (44.2%), 5 NRAS (3.1%), 2 HRAS (1.0%) and 1 KRAS (0.5%) mutations were found, as well as 9 RET/PTC1 (4.6%) and 1 RET/PTC3 (0.5%) translocations. No genetic alteration was seen in the non tumorous control thyroid tissues. No correlation was detected between the genetic variants and the pathological subtypes of papillary cancer as well as the severity of the disease. Our results are only partly concordant with the data found in the literature.

    Attachment of microcystallites to cellular membranes may be an important component of the pathophysiology of many diseases including urolithiasis. This study attempts to characterize the interaction of calcium oxalate (CaOx) crystals and apatite (AP) crystals with renal papillary collecting tubule (RPCT) cells in primary culture. Primary cultures of RPCT cells showed the characteristic monolayer growth with sporadically interspersed clumped cells. Cultures were incubated with [ 14 C]CaOx crystals, and the crystals that bound were quantified by microscopy and adherent radioactivity. Per unit of cross-sectional area, 32 times more CaOx crystals were bound to the clumps than to the monolayer. CaOx adherence demonstrated concentration-dependent saturation with a β value (fraction of cell culture area binding CaOx crystals) of 0.179 and a 1/α ox value of 287 μg/cm 2 . On incubation with AP crystals, CaOx binding demonstrated concentration-dependent inhibition with a 1/α AP value of 93 μg/cm 2 . Microcystallite adherence to RPCT cells demonstrates selectivity for cellular clumps, saturation, and inhibition. These features suggest specific binding

    Molecular pathways associated with pathogenesis of sporadic papillary renal cell carcinoma (PRCC), the second most common form of kidney cancer, are poorly understood. We analyzed primary tumor specimens from 35 PRCC patients treated by nephrectomy via gene expression analysis and tissue microarrays constructed from an additional 57 paraffin-embedded PRCC samples via immunohistochemistry. Gene products were validated and further studied by Western blot analyses using primary PRCC tumor samples and established renal cell carcinoma cell lines, and potential associations with pathologic variables and survival in 27 patients with follow-up information were determined. We show that the expression of E2-EPF ubiquitin carrier protein, which targets the principal negative regulator of hypoxia-inducible factor (HIF), von Hippel-Lindau protein, for proteasome-dependent degradation, is markedly elevated in the majority of PRCC tumors exhibiting increased HIF1α expression, and is associated with poor prognosis. In addition, we identified multiple hypoxia-responsive elements within the E2-EPF promoter, and for the first time we demonstrated that E2-EPF is a hypoxia-inducible gene directly regulated via HIF1. These findings reveal deregulation of the oxygen-sensing pathway impinging on the positive feedback mechanism of HIF1-mediated regulation of E2-EPF in PRCC.

    Background In recent years, some reports have suggested that papillary thyroid cancers are more frequently associated with lymphocytic thyroiditis or Hashimoto's thyroiditis. This study investigated a potential increase in the prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients. Materials and Methods We used national epidemiological survey data on thyroid cancer patients diagnosed in 1999, 2005, and 2008. A retrospective medical record survey was conducted by representative sampling of a national cancer incidence database. The analysis included 5,378 papillary thyroid cancer patients aged 20–79 years. We calculated the age-standardized prevalence and age-adjusted prevalence ratios using a binomial regression model with a log link for the prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients by sex for each year. Results The prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients was 4.0% and 12.8% for men and women in 1999, 6.5% and 24.6% in 2005, and 10.7% and 27.6% in 2008, respectively. Between 1999 and 2008, the age-standardized prevalence of chronic lymphocytic thyroiditis increased 4.1-fold in male patients and 2.0-fold in female patients with papillary thyroid cancer. The prevalence of other thyroid diseases, however, did not increase in either gender. Conclusions Among Korean papillary thyroid cancer patients, the prevalence of chronic lymphocytic thyroiditis increased between 1999 and 2008, whereas the prevalence of other thyroid disorders did not change.

    Metastasis to regional lymph nodes is a common step in the progression of cancer. Recent evidence suggests that tumor production of CXCR4 promotes lymph node metastasis. Nitric oxide (NO) may also increase metastatic ability in human cancers. Nitrite/nitrate levels and functional CXCR4 expression were assessed in K1 and B-CPAP papillary thyroid carcinoma (PTC) cells after induction and/or inhibition of NO synthesis. CXCR4 expression was also analyzed in primary human PTC. The relationship between nitrotyrosine levels, which are a biomarker for peroxynitrate formation from NO in vivo, CXCR4 expression, and lymph node status was also analyzed. Production of nitrite/nitrate and functional CXCR4 expression in both cell lines was increased by treatment with the NO donor DETA NONOate. The NOS inhibitor L-NAME eliminated this increase. Positive CXCR4 immunostaining was observed in 60.7% (34/56) of PTCs. CXCR4 expression was significantly correlated with nitrotyrosine levels and lymph node metastasis in human PTC. Our data indicate that NO stimulates CXCR4 expression in vitro. Formation of the NO biomarker nitrotyrosine was also correlated with CXCR4 expression and lymph node metastasis in human PTC. NO may induce lymph node metastasis via CXCR4 induction in papillary thyroid carcinoma

    Primary pathologic processes involving the renal pyramids such as papillary necrosis, drug-induced necrosis or calcinosis, cysts, neoplasms, and medullary nephrocalcinosis are rare. Thirty-four patients with primary renal pyramid diseases underwent US evaluation for altered morphology; a 5-MHz transducer was used. In 20 patients site-specific changes in the pyramid (e.g., papillary necrosis at the apex, small cysts at the base in medullary cystic disease, tubular calcification in MSK, corticomedullary hyperechogenicity in oxalosis) were noted on US. Sonographic delineation of the site and pattern of pathologic changes in the renal pyramid may help to identify specific diseases

    Uterine serous carcinoma (USC) represents an aggressive variant of endometrial cancer and accounts for a large proportion of deaths annually. HER2/neu amplification is associated with USC in approximately 30-35% of cases. The objective of this study was to determine the sensitivity of a panel of primary USC cell lines to the small tyrosine kinase inhibitor neratinib, an ErbB1 and HER2 inhibitor, both in vitro and in vivo. HER2/neu amplification was determined by immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) in 24 USC cell lines. Flow cytometry was used to determine the effects of neratinib on cell viability, cell cycle distribution and signaling in vitro. Mice harboring HER2/neu amplified xenografts were treated with neratinib to assess the efficacy of the drug in vivo. HER2/neu amplification was noted in 8/24 primary cell lines. Data regarding the efficacy of neratinib was determined using 4 HER2 amplified cell lines and 4 non-amplified cell lines with similar growth rates. Data revealed that cell lines with HER2/neu amplification were exquisitely more sensitive to neratinib compared to non-amplified cell lines (mean ± SEM IC50: 0.011μM ± 0.0008 vs. 0.312μM ± 0.0456 pNeratinib caused arrest in the G0/G1 phase of the cell cycle and resulted in decreased autophosphorylation of HER2 and activation of S6. Neratinib treated mice harboring xenografts of HER2/neu amplified USC showed delayed tumor growth and improved overall survival compared to vehicle (p=0.0019). Neratinib may be a potential treatment option for patients harboring HER2/neu amplified USC. Clinical trials for this subset of endometrial cancer patients are warranted.

    Abstract Abdominal wall tumors are sometimes diagnosed as metastases of ovarian cancer, however, primary peritoneal tumors should be taken into consideration in the final diagnosis. A 49-year-old female patient was admitted in our Department for the excision of a pulpable abdominal wall lump, with no other abnormalities shown on imaging investigation. On histology examination, the excised specimen revealed characteristics of metastatic high-grade serous ovarian carcinoma. Total hysterectomy, bilateral oophorectomy, omentectomy and appendectomy were performed. No signs of malignancy were proved on histology, leading to the final diagnosis of a primary serous peritoneal tumor. This is the third described case of solitary primary serous peritoneal tumor located in the abdominal wall. This condition should be included in the differential diagnosis of a probable metastatic ovarian carcinoma, as both present similar histologic characteristics. PMID:28616156

    Abdominal wall tumors are sometimes diagnosed as metastases of ovarian cancer, however, primary peritoneal tumors should be taken into consideration in the final diagnosis. A 49-year-old female patient was admitted in our Department for the excision of a pulpable abdominal wall lump, with no other abnormalities shown on imaging investigation. On histology examination, the excised specimen revealed characteristics of metastatic high-grade serous ovarian carcinoma. Total hysterectomy, bilateral oophorectomy, omentectomy and appendectomy were performed. No signs of malignancy were proved on histology, leading to the final diagnosis of a primary serous peritoneal tumor. This is the third described case of solitary primary serous peritoneal tumor located in the abdominal wall. This condition should be included in the differential diagnosis of a probable metastatic ovarian carcinoma, as both present similar histologic characteristics.

    This report documents 3 pediatric papillary thyroid carcinoma cases with associated Hashimoto thyroiditis. In all 3 cases, hypoechoic nodules accompanied by multiple echogenic spots were noted on sonography of the thyroid. Hashimoto thyroiditis was suspected on the basis of positive thyroid autoantibody test results and pathologic examinations of thyroidectomy specimens, which revealed chronic thyroiditis with lymphocytic infiltration as the background of papillary thyroid carcinoma development. The potential for papillary carcinoma development warrants close follow-up, and meticulous sonographic examinations must be performed in children with Hashimoto thyroiditis. © 2014 by the American Institute of Ultrasound in Medicine.

    Well-differentiated papillary mesothelioma is a rare tumor occurring predominantly in the peritoneum of young women, a few with history of asbestos exposure. A 28-year-old woman presented with ascites and pain abdomen. Ultrasonography and computed tomography scan of the abdomen revealed a mass in the retroperitoneum measuring 15 cm × 12 cm. Histopathological examination along with immunohistochemistry (IHC) confirmed it to be a papillary mesothelioma in the peritoneum. It is difficult to differentiate from more common malignant mesothelioma and papillary adenocarcinoma, which also have poorer prognosis. The difficulty can be resolved by clinico-radiological correlation along with histopathological examination and IHC.

    We report an extremely rare case of papillary thyroid microcarcinoma (PTMC in the thyroid Epub ahead of print pyramidal lobe (TPL. A 48-year-old woman underwent ultrasound-guided fine-needle aspiration for a small thyroid nodule in the right lobe in local clinic, and it revealed a malignant cytology. On preoperative ultrasonography for tumor staging in our hospital, another small suspiciously malignant hypoechoic nodule was detected in the left TPL. Total thyroidectomy and central nodal dissection were performed. Histopathology confirmed PTMCs in the left TPL and both thyroid lobes. Ultrasonography for TPL should be required for complete evaluation of possible multifocality of thyroid malignancy.

    The pseudo papillary solid tumor of the pancreas, also known as Frantz's tumor, is a rare disease, taking place in approximately 0.17% to 2.7% of non-endocrine tumors of the pancreas. Recently, the increase of its incidence has been noted with more than two-thirds of the total cases described in the last 10 years. A possible explanation is a greater knowledge of the disease and a greater uniformity of conceptualization in the last years. Generally, it affects young adult females. In most of the series, the tumor principally attacks the body and tail of the pancreas. The objective of the present report is to present the diagnostic and therapeutic option used in this rare pancreatic tumor of low-grade malignancy. (author)

    Aurora-A is a potential oncogene and therapeutic target in ovarian carcinoma. It is involved in mitotic events and overexpression leads to centrosome amplification and chromosomal instability. The objective of this study was to evaluate the clinical significance of Aurora-A and DNA ploidy in serous ovarian carcinoma. Serous ovarian carcinomas were analysed for Aurora-A protein by immunohistochemistry (n=592), Aurora-A copy number by CISH (n=169), Aurora-A mRNA by real-time PCR (n=158) and DNA ploidy by flowcytometry (n=440). Overexpression of Aurora-A was found in 27% of the tumors, cytoplasmic overexpression in 11% and nuclear in 17%. The cytoplasmic and nuclear overexpression were nearly mutually exclusive. Both cytoplasmic and nuclear overexpression were associated with shorter survival, high grade, high proliferation index and aberrant p53. Interestingly, only cytoplasmic expression was associated with aneuploidy and expression of phosphorylated Aurora-A. DNA ploidy was associated with poor patient outcome as well as aggressive clinicopathological parameters. In multivariate analysis, Aurora-A overexpression appeared as an independent prognostic factor for disease-free survival, together with grade, stage and ploidy. Aurora-A protein expression is strongly linked with poor patient outcome and aggressive disease characteristics, which makes Aurora-A a promising biomarker and a potential therapeutic target in ovarian carcinoma. Cytoplasmic and nuclear Aurora-A protein may have different functions. DNA aneuploidy is a strong predictor of poor prognosis in serous ovarian carcinoma. Copyright © 2010 Elsevier Inc.

    To evaluate the effect of photobleaching on fundus autofluorescence (FAF) images in acute central serous chorioretinopathy. We obtained prephotobleaching and postphotobleaching images using an Optomap 200Tx, and photobleaching was induced with a Heidelberg Retina Angiograph 2. Degrees of photobleaching were assessed as grayscale values in Optomap images. Concordances among the three kinds of images were analyzed. Hyper-AF lesions in prephotobleaching images were classified as Type 1 (changed to normal-AF after photobleaching) and Type 2 (unchanged after photobleaching). The FAF composite patterns of central serous chorioretinopathy lesions were classified as diffuse or mottled. Initial and final best-corrected visual acuity, central retinal thickness, and disease duration were compared according to fovea FAF type. Forty-one eyes of 41 patients were analyzed. The lesion brightness of postphotobleaching Optomap FAF showed greater concordance with Heidelberg Retina Angiograph 2 FAF (94.74%) than the prephotobleaching Optomap FAF (80.49%). Eyes with Type 1 fovea had greater initial and final best-corrected visual acuity (20/23 vs. 20/41, 20/21 vs. 20/32, P < 0.0001, P = 0.001, respectively) and shorter disease duration (19.68 ± 12.98 vs. 51.55 ± 44.98 days, P = 0.043) than those with Type 2 fovea. However, eyes with diffuse Type 2 fovea had only lower initial and final best-corrected visual acuity (20/23 vs. 20/45, 20/21 vs. 20/36, P < 0.0001, P < 0.0001, respectively) than those with Type 1 fovea. Understanding the photobleaching effect is necessary for the accurate interpretation of FAF images. Furthermore, comparing prephotobleaching and postphotobleaching FAF images may be helpful for estimation of lesion status in central serous chorioretinopathy.

    Histopathological examination of material from prophylactic salpingo-oophorectomies performed in patients at genetic risk of ovarian cancer can reveal abnormalities interpreted as possible pre-cancerous "ovarian dysplasia" and tubal precursors lesions. We sought to study the morphological features and immunohistochemical expression patterns of neoplasia-associated markers in prophylactically removed ovaries and fallopian tubes (pBSO) in comparison with a group of serous tubal intraepithelial carcinoma (STIC) and non-cancerous controls. Morphological features and immunohistochemical expression patterns of Ki-67 (for proliferation biomarker), p53 (key pathway of mullerian serous tumorogenesis), Bcl2 (anti-apoptotic), γH2AX (a double-strand breaks marker) and ALDH1 (a stem cell marker significantly associated with early-stage ovarian cancer) were blindly evaluated by two pathologists in 111 pBSO, 12 STICs and 116 non-cancerous salpingo-oophorectomies (control group) (nBSO). Morphological ovarian and tubal dysplasia scores were significantly higher in the pBSO than in controls (respectively, 8.8 vs 3.12, pSTICs compared with the controls whereas expression patterns of Ki67, p53 and bcl2 were low to moderate in the pBSO group. STICs overexpressed Ki67 and p53 while bcl2 expression was low; Interestingly, ALDH1 expression was low in non dysplastic epithelium, high in dysplasia and constantly low in STICs. The morphological and immunohistochemical profile of tubo-ovarian dysplasia and STICs might be consistent with progression toward neoplastic transformation in the Serous Carcinogenesis Sequence. These changes may be pre-malignant and could represent an important phase in early neoplasia. ALDH1 activation in pBSO samples and its extinction in STICs should be considered as a target for prevention. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    SPECT/CT improves localization of single photon-emitting radiopharmaceuticals. To determine the utility of SPECT/CT in children with papillary thyroid carcinoma. 20 SPECT/CT and planar studies were reviewed in 13 children with papillary thyroid carcinoma after total thyroidectomy. Seven studies used I-123 and 13 used I-131, after elevating TSH by T4 deprivation or intramuscular thyrotropin alfa. Eight children had one study and five children had two to four studies. Studies were performed at initial post-total thyroidectomy evaluation, follow-up and after I-131 treatment doses. SPECT/CT was performed with a diagnostic-quality CT unit in 13 studies and a localization-only CT unit in 7. Stimulated thyroglobulin was measured (except in 2 cases with anti-thyroglobulin antibodies). In 13 studies, neck activity was present but poorly localized on planar imaging; all foci of uptake were precisely localized by SPECT/CT. Two additional foci of neck uptake were found on SPECT/CT. SPECT/CT differentiated high neck uptake from facial activity. In six studies (four children), neck uptake was identified as benign by SPECT/CT (three thyroglossal duct remnants, one skin contamination, two by precise anatomical CT localization). In two children, SPECT/CT supported a decision not to treat with I-131. When SPECT/CT was unable to identify focal uptake as benign, stimulated thyroglobulin measurements were valuable. In three of 13 studies with neck uptake, SPECT/CT provided no useful additional information. SPECT/CT precisely localizes neck iodine uptake. In small numbers of patients, treatment is affected. SPECT/CT should be used when available in thyroid carcinoma patients. (orig.)

    To describe magnetic resonance imaging (MRI) features of intravascular papillary endothelial hyperplasia (IPEH), to identify findings differentiating IPEH of the finger from that of other locations, and to correlate these with pathology. Nineteen patients with 20 I.E. masses of the finger (n = 13) and other locations (n = 7) were evaluated. All patients underwent MRI, and the results were correlated with pathology. Seventeen IPEHs, including all IPEHs of the finger, were located in the subcutis, the three other lesions in the muscle layer. On T1WI, all masses were isointense or slightly hyperintense. IPEHs of the finger (n = 13) revealed focal hyperintense nodules (n = 2) or central hypointensity (n = 2) on T1WI, hypointensity with a hyperintense rim (n = 7), hyperintensity with hypointense nodules (n = 5), or isointensity with a hypointense rim (n = 1) on T2WI, and rim enhancement (n = 5), heterogeneous enhancement with nodular nonenhanced areas (n = 6), peripheral nodular enhancement (n = 1), or no enhancement (n = 1) on gadolinium-enhanced T1WI. IPEHs of other locations (n = 7) demonstrated focal hyperintense nodules (n = 5) on T1WI, hyperintensity with hypointense nodules (n = 5) or heterogeneous signal intensity (n = 2) on T2WI, and rim or rim and septal enhancement (n = 6) or peripheral nodular enhancement (n = 1). Microscopically, IPEHs were composed of thrombi that were hypointense on T2WI and papillary endothelial proliferations that showed T2 hyperintensity and enhancement. MRI of finger IPEH reveals well-demarcated subcutaneous masses with hypointensity or hypointense nodules with peripheral hyperintensity on T2WI, as well as peripheral enhancement. T1 hyperintense nodules, internal heterogeneity on T2WI, and septal enhancement are more common in IPEH of other locations. (orig.)

    Full Text Available Intravascular papillary endothelial hyperplasia is a benign nonneoplastic vascular lesion that consists of endothelial cells with abundant vascular tissue with papillary proliferation. An adult female had a painless growing dark red nodule on the left side of the lower lip and often touched and gnawed at it for more than 4 years. The lesion was a tender, smooth mass approximately 1 cm in diameter without discoloration reaction. Magnetic resonance imaging of the lesion showed specific findings. She was diagnosed clinically as having mimicked hemangioma, and the lesion was totally excised under local anesthesia. Histopathological examination revealed that papillary proliferated endothelial cells with venous pool, and the lesion was diagnosed as intravascular papillary endothelial hyperplasia associated with venous pool. There has been no recurrence for more than 1 year. Despite the benign nature of this lesion, it could have been mistaken for a malignant tumor because of its clinical course and radiologic findings.

    Breast masses occur in men far less commonly than women and are infrequently subjected to fine-needle aspiration (FNA) biopsy. Papillary lesions of the male breast are rare and are comprised of a spectrum of lesions ranging from papillary hyperplasia in gynecomastia to invasive papillary carcinoma. The following study describes the cytomorphology of papillary breast lesions in 11 men. The patients ranged in age from 23 to 78 years old and each presented with an unilateral subareolar or periareolar breast mass that varied in size from 0.5 to 3 cm. Two patients presented with bloody nipple discharge. Archival material (8-year period) from FNA biopsies of papillary lesions of the male breast was reviewed. The reviewed cases were correlated with appropriate clinicopathologic follow-up. The smears had variable cellularity but all showed papillary clusters of mammary epithelial cells with and without fibrovascular cores. Single epithelial cells with a high nuclear-to-cytoplasmic ratio and eccentric nuclei were seen in all smears; however, these were more numerous in cases of adenocarcinoma. Hemosiderin-laden macrophages were present in all cases. Nipple discharge was seen only in the 2 benign lesions. All adenocarcinomas occurred in older men. The only cytologic criteria that differentiated benign from malignant papillary lesions were marked cellularity and the presence of abundant 3-dimensional clusters. To the best of the authors' knowledge, the current series is the largest in the English literature to date that examines the cytomorphologic features of papillary breast lesions in men.

  10. Aberrantly methylated genes in human papillary thyroid cancer and their association with BRAF/RAS mutation.

    Directory of Open Access Journals (Sweden)

    Yasuko eKikuchi

    2013-12-01

    Full Text Available Cancer arises through accumulation of epigenetic and genetic alteration. Aberrant promoter methylation is a common epigenetic mechanism of gene silencing in cancer cells. We here performed genome-wide analysis of DNA methylation of promoter regions by Infinium HumanMethylation27 BeadChip, using 14 clinical papillary thyroid cancer samples and 10 normal thyroid samples. Among the 14 papillary cancer cases, 11 showed frequent aberrant methylation, but the other three cases showed no aberrant methylation at all. Distribution of the hypermethylation among cancer samples was non-random, which implied existence of a subset of preferentially methylated papillary thyroid cancer. Among 25 frequently methylated genes, methylation status of six genes (HIST1H3J, POU4F2, SHOX2, PHKG2, TLX3, HOXA7 was validated quantitatively by pyrosequencing. Epigenetic silencing of these genes in methylated papillary thyroid cancer cell lines was confirmed by gene re-expression following treatment with 5-aza-2'-deoxycytidine and trichostatin A, and detected by real-time RT-PCR. Methylation of these six genes was validated by analysis of additional 20 papillary thyroid cancer and 10 normal samples. Among the 34 cancer samples in total, 26 cancer samples with preferential methylation were significantly associated with mutation of BRAF/RAS oncogene (P=0.04, Fisher’s exact test. Thus we identified new genes with frequent epigenetic hypermethylation in papillary thyroid cancer, two subsets of either preferentially methylated or hardly methylated papillary thyroid cancer, with a concomitant occurrence of oncogene mutation and gene methylation. These hypermethylated genes may constitute potential biomarkers for papillary thyroid cancer.

    2017-01-01

    Papillary thyroid cancer (PTC) is the most common thyroid malignancy, and cervical nodal metastases are frequent at presentation. The most common site for nodal metastases from PTC is the central compartment of the ipsilateral neck in the paratracheal and pretracheal regions. The decision to resect these lymph nodes at the time of thyroidectomy often depends on if nodes with suspected malignancy can be identified preoperatively. If nodal spread to the central neck nodes is known, then the consensus is to remove all nodes in this area. However, there remains significant controversy regarding the utility of removing central neck lymph nodes for prophylactic reasons. Herein, we review the potential utility of central neck lymph node dissection as well as the risks of performing this procedure. As well, we review the potential of molecular testing to stratify patients who would most benefit from this procedure. We advocate a selective approach in which patients undergo clinical neck examination coupled with ultrasound to detect any concerning lymph nodes that warrant additional evaluation with either fine needle aspiration or excisional biopsy in the operating room. In lieu of clinical lymphadenopathy, we suggest the use of patient and disease characteristics as identified by multiple groups, such as the American Thyroid Association and European Society of Endocrine Surgeons, which include extremes of ages, large primary tumor size, and male gender, when deciding to perform central neck lymph node dissection. Patients should be educated on the potential long-terms risks versus the lack of known long-term benefits.

    The goal of this study is to determine the clinicopathologic differences in patients with papillary thyroid carcinoma (PTC) with or without chronic lymphocytic thyroiditis (CLT). We reviewed the medical records of 195 consecutive PTC patients who underwent total thyroidectomy and bilateral central lymph node dissection from April 2008 to March 2010. The differences in clinicopathologic factors, such as age, gender, size of primary tumor, perithyroidal invasion, lymphovascular invasion, capsular invasion, and central lymph node (CLN) metastasis, were analyzed in PTC patients with or without CLT. Among 195 patients, 56 (28.7%) had co-existing CLT. Patients with CLT had the following characteristics as compared to patients without CLT: significantly younger, female predominance, smaller tumor size, and lower incidence of capsular invasion (p = 0.038, 0.006, 0.037, and 0.026, respectively). Also, patients with CLT (12.5%) had a significantly lower incidence of CLN metastases than patients without CLT (28.1%; p = 0.025) based on univariate analysis. Moreover, multivariate analysis showed that younger age (p = 0.042, odds ratio = 1.033) and female gender (p = 0.012, odds ratio = 6.865) are independent clinical factors in patients with CLT compared to patients without CLT. CLT was shown to be commonly associated with PTC. Compared to patients with PTC without CLT, patients with CLT were younger with a female predominance, which are the most important and well-known prognostic variables for thyroid cancer mortality.

    Mixed connective tissue disease (MCTD) is a connective tissue disorder characterized by high titers of distinct antibodies: U1 ribonucleoprotein with clinical features seen in systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), dermatomyositis (DM), polymyositis, and scleroderma. The association of SLE and DM with various cancers of the thyroid has been reported in the literature. However, there have been no reports associating MCTD with thyroid cancer. We present a 58-year-old woman diagnosed with MCTD with co-morbid interstitial lung disease that has remained stable for 10 years, who developed papillary thyroid carcinoma (PTC) 10 years after initial diagnosis. We theorize that: 1) MCTD may have been a primary diagnosis complicated by PTC, or 2) MCTD may have been an initial presentation of paraneoplastic syndrome of silent PTC, because her symptoms of MCTD significantly improved after total thyroidectomy. To the best of our knowledge, this is the first case report to associate MCTD with PTC. It highlights the importance of maintaining a high index of suspicion for thyroid malignancy in MCTD patients.

    Full Text Available BackgroundObesity is associated with aggressive pathological features and poor clinical outcomes in breast and prostate cancers. In papillary thyroid carcinoma (PTC, these relationships remain still controversial. This study aimed to evaluate the associations between body mass index (BMI and the clinical outcomes of patients with PTC.MethodsThis retrospective study included 1,189 patients who underwent total thyroidectomy for PTCs equal to or larger than 1 cm in size. Clinical outcomes were evaluated and compared based on the BMI quartiles.ResultsThere were no significant associations between BMI quartiles and primary tumor size, extrathyroidal invasion, cervical lymph node metastasis, or distant metastasis. However, an increase in mean age was associated with an increased BMI (P for trend <0.001. Multifocality and advanced tumor-node-metastasis (TNM stage (stage III or IV were significantly associated with increases of BMI (P for trend 0.02 and <0.001, respectively. However, these associations of multifocality and advanced TNM stage with BMI were not significant in multivariate analyses adjusted for age and gender. Moreover, there were no differences in recurrence-free survivals according to BMI quartiles (P=0.26.ConclusionIn the present study, BMI was not associated with the aggressive clinicopathological features or recurrence-free survivals in patients with PTC.

    The Cancer Genome Atlas (TCGA) Network recently comprehensively catalogued the molecular aberrations in 487 high-grade serous ovarian cancers, with much remaining to be elucidated regarding the microRNAs (miRNAs). Here, using TCGA ovarian data, we surveyed the miRNAs, in the context of their predicted gene targets. Integration of miRNA and gene patterns yielded evidence that proximal pairs of miRNAs are processed from polycistronic primary transcripts, and that intronic miRNAs and their host gene mRNAs derive from common transcripts. Patterns of miRNA expression revealed multiple tumor subtypes and a set of 34 miRNAs predictive of overall patient survival. In a global analysis, miRNA:mRNA pairs anti-correlated in expression across tumors showed a higher frequency of in silico predicted target sites in the mRNA 3'-untranslated region (with less frequency observed for coding sequence and 5'-untranslated regions). The miR-29 family and predicted target genes were among the most strongly anti-correlated miRNA:mRNA pairs; over-expression of miR-29a in vitro repressed several anti-correlated genes (including DNMT3A and DNMT3B) and substantially decreased ovarian cancer cell viability. This study establishes miRNAs as having a widespread impact on gene expression programs in ovarian cancer, further strengthening our understanding of miRNA biology as it applies to human cancer. As with gene transcripts, miRNAs exhibit high diversity reflecting the genomic heterogeneity within a clinically homogeneous disease population. Putative miRNA:mRNA interactions, as identified using integrative analysis, can be validated. TCGA data are a valuable resource for the identification of novel tumor suppressive miRNAs in ovarian as well as other cancers.

    Three types of small cardiac lesions were described and illustrated: (1) focal type of papillary muscle fibrosis, evidently a healed infarct of the papillary muscle present in 13% of the autopsies, is a histologically characteristic lesion associated with coronary artery disease and healed myocardial infarction; (2) diffuse type of papillary muscle fibrosis, probably an aging change present in almost half of the autopsies, is associated with sclerosis of the arteries in the papillary muscle, is identifiable histologically; and apparently is not associated with any cardiac abnormality; and (3) focal cardiac myocytolysis, a unique histologic lesion, usually multifocal without predilection for any area of the heart, is associated with ischemic heart disease, death due to cancer complicated by non-bacterial thrombotic endocarditis and microthrombi in small cardiac arteries as well as with other diseases. Differentiation of the 2 types of papillary muscle fibrosis is important in the study of papillary muscle and mitral valve dysfunction. Focal cardiac myocytolysis may contribute to the fatal extension of myocardial infarcts.

    Papillary fibroelastomas (PFEs) are one of the most frequent primary cardiac tumors and occur more often in patients with hypertrophic obstructive cardiomyopathy (HOCM). PFEs have been linked to an increased risk of neurological events. We report a case of a 59-year-old woman with HOCM in whom echocardiography (transthoracic and transesophageal, using 2D and 3D techniques) revealed multiple masses in various locations in the left cardiac chambers. Surgical excision of the cardiac tumors and aortic valve replacement was performed and the pathologic report confirmed the diagnosis of PFEs. Patient followup using ultrasonography is crucial since recurrence is a possibility. Current cardiac ultrasound techniques are essential for diagnosing and for guiding the management of these conditions.

    Ectopic thyroid tissue results from abnormal embryologic development and migration of the thyroid gland. True malignant transformation in ectopic thyroid tissue is extremely rare and is always diagnosed after surgical excision of the lesion by pathology examinations. There are well-documented cases of ectopic thyroid cancer while primary tumoral lesion occurs in the orthotopic thyroid, but only rare cases of ectopic PTC without any evidence of occult thyroid cancer in the orthotopic thyroid or cervical lymph nodes have been reported. We report on a 39 year old woman who was operated for a mediastinal mass. The initial diagnosis was a malignant thymic lesion, which was later confirmed to be a papillary thyroid carcinoma. Consequently, total thyroidectomy was performed and pathology report showed normal thyroid tissue with no evidence of any neoplastic involvement. Until now, only one similar case has been reported

    A case of multifocal pancreatic serous cystadenoma with atypical cells is reported. The patient was a 72-yr-old female who complained of jaundice. The distal common bile duct was obstructed, and the proximal bile duct was remarkably dilated on cholangiography. The main portal vein was obstructed and collateral vessels had developed on portal angiography. Total pancreatectomy was performed. The resected specimen contained one tumor in the head of the pancreas, five in the body, and one in the tail. The tumors of the head and body were morphologically the same. Microscopically, both contained spongelike multilocular cysts on their cut surfaces. These cysts were covered with low cuboid epithelium containing clear cytoplasm and abundant glycogen. Neural invasion was also found. The tumor cells exhibited an increased N/C ratio, variable nuclear size, irregular nuclear margins, and coarse nuclear chromatin. These tumors had aneuploid nuclear DNA with a DNA index of 1.9 and a proliferation index of 0.28. We feel that it is necessary to reconsider the biological concept of serous cystadenoma.

    Aim: To analyse the morphological magnetic resonance imaging (MRI) features of borderline ovarian tumours (BOT) and to evaluate whether MRI can be used to distinguish serous from mucinous subtypes. Materials and methods: A retrospective study of 72 patients who underwent BOT resection was undertaken. MRI images were reviewed blindly by two radiologists to assess MRI features: size, tumour type, grouped and irregular thickened septa, number of septa, loculi of different signal intensity, vegetations, solid portion, signal intensity of vegetations, normal ovarian parenchyma, and pelvic ascites. Statistical analysis was performed using Mann–Whitney and Fisher's exact tests. Logistic regression analysis was used to assess the predictive value of the MRI findings for histological subtypes. Results: At histology, there were 33 serous BOT (SBOT) and 39 mucinous BOT (MBOT). Predictive MRI criteria for SBOT were bilaterality, predominantly solid tumour, and the presence of vegetations, especially exophytic or with a high T2 signal (p < 0.01), whereas predictive MRI criteria for MBOT were multilocularity, number of septa, loculi of different signal intensity, and grouped and irregular thickened septa (p < 0.01). Using multivariate analysis, vegetations were independently associated with SBOT [odds ratio (OR) = 29.5] and multilocularity with MBOT (OR = 3.9). Conclusion: Vegetations and multilocularity are two independent MRI features that can help to distinguish between SBOT and MBOT.

    A newly developed murine monoclonal antibody, DS6, immunohistochemically reacts with an antigen, CA6, that is expressed by human serous ovarian carcinomas but not by normal ovarian surface epithelium or mesothelium. CA6 has a limited distribution in normal adult tissues and is most characteristically detected in fallopian tube epithelium, inner urothelium and type 2 pneumocytes. Pre-treatment of tissue sections with either periodic acid or neuraminidase from Vibrio cholerae abolishes immunoreactivity with DS6, indicating that CA6 is a neuraminidase-sensitive and periodic acid-sensitive sialic acid glycoconjugate ("sialoglycotope"). SDS-PAGE of OVCAR5 cell lysates has revealed that the CA6 epitope is expressed on an 80 kDa non-disulfide-linked glycoprotein containing N-linked oligosaccharides. Two-dimensional non-equilibrium pH gradient gel electrophoresis indicates an isoelectric point of approximately 6.2 to 6.5. Comparison of the immunohistochemical distribution of CA6 in human serous ovarian adenocarcinomas has revealed similarities to that of CA125; however, distinct differences and some complementarity of antigen expression were revealed by double-label, 2-color immunohistochemical studies. The DS6-detected CA6 antigen appears to be distinct from other well-characterized tumor-associated antigens, including MUC1, CA125 and the histo-blood group-related antigens sLea, sLex and sTn.

    Full Text Available Purpose. Subthreshold diode micropulse laser (SDM treatment is believed to be safe method of treating clinical entities involving retinal edema. We present a case of serous edematous reaction of the retina to SDM treatment. Methods. Case report. Results. A patient with chronic central serous chorioretinopathy (CSCR was treated with SDM Yellow multispot laser. Procedure had been preceded by careful titration of the laser power, which after achieving of the threshold parameter was decreased by 50%. The follow-up visit two days after treatment revealed significant central retinal edema and subretinal fluid. Fundus autofluorescence image showed thermal reaction from the RPE in the form of small spots of hyperfluorescence corresponding to the laser multispot pattern used for treatment. Retinal edema resolved after topical bromfenac and single intravitreal bevacizumab injection. Slight pigmentary reaction from the RPE persisted. Conclusion. In the treatment of CSCR, there is a need to significantly reduce threshold SDM power parameters or simply use very low power without titration.

    The authors report about the efficacy of inserted tympanostomy tube in children with serous otitis media. The aim of the authors was to assess the status of eardrum, the function of Eustachian tube and hearing level 10 years after the use of tympanostomy tube. Patients filled out a questionnaire and microscopic examination of tympanic membrane, tympanometry, Eustachian tube function examination, and audiometry tests were performed. In the period of 2003-2004, ventilation tube insertion was performed in 711 patients in the ENT Department of Pediatric Health Center of University of Szeged. In 349 patients adenotomy and tympanostomy tube insertion, in 18 cases tonsillectomy and grommet insertion and in 344 patients only typmanostomy tube insertion were performed. Due to objective difficulties (address change, no phone number) 453 patients were asked for control test and 312 persons accepted the invitation. Normal hearing level was found in 84.6% of patients and normal tympanometry result occurred in 82%. Tympanic ventilation disorder, perforation of tympanic membrane, sensorineural hearing loss and sensorineural hearing loss due to noise exposure were diagnosed. Application of tympanostomy tube is effective in the treatment of serous otitis media resulting from ventilation disorder. The authors draw attention to the importance of tympanometry examination to prevent the adhesive processes and cholesteatoma in chronic ventilation disorder of the middle ear.

    We report the case of a patient with Cushing disease revealed by bilateral central serous chorioretinopathy (CSCR). We present the clinical history, physical findings, laboratory results, and imaging studies of a 53-year-old Chinese woman with a Cushing disease revealed by bilateral CSCR. The association with CSCR and the pertinent literature are reviewed. A 53-year-old patient initially presented to the Department of Ophthalmology with a 4-week history of decreased vision in the left eye. Standard ophthalmologic examination and fluorescein angiography established the diagnosis of bilateral CSCR. Systemic clinical signs and biochemical analysis indicated hypercortisolism. Magnetic resonance imaging (MRI) of the pituitary gland showed a left-side lesion compatible with a microadenoma. The diagnosis of Adrenocorticotropic hormone (ACTH)-dependent Cushing syndrome secondary to a pituitary microadenoma was selected. Endoscopic endonasal transsphenoidal surgery was performed and the pituitary adenoma was successfully removed. The histology confirmed the presence of ACTH-immunopositive pituitary adenoma. Early postoperative morning cortisol levels indicated early remission. At 6 weeks postoperatively, the patient's morning cortisol remains undetectable, and serous retinal detachments had regressed. CSCR is an uncommon manifestation of endogenous Cushing syndrome. It can be the first presentation of hypercortisolism caused by Cushing disease. CSCR should be considered when assessing patients with Cushing syndrome complaining of visual disorders. On the other hand, it is useful in patients with an atypical form of CSCR to exclude Cushing's syndrome.

    Objective The purpose of this study was to determine the prevalence of incidentally discovered serous tubal intraepithelial carcinoma in women without a genetic risk for or history of high grade serous carcinoma (HGSC) in the gynecologic tract. All pathology reports at our institution that included bilateral salpingectomies from January 2006-December 2011 were examined in women >50years old in which the entire tube or the distal one-third was examined histologically with the complete (proximal and distal fallopian tube) or modified (distal one third of the tube) SEE-FIM protocol. Cases were divided into: Group 1, a history of or known risk factors (BRCA1 or BRCA2 mutations) for HGSC and Group 2, those without these attributes for whom a STIC would be unexpected (incidental). Women undergoing unspecified "risk-reducing" procedures were included in Group 1. Of 4051 identified total, 2268 had complete examination of the distal fallopian tube and were age 50 or above. Of these, 1747 were in group 2. Two STICs were identified (0.1%), one associated with a grade 2 endometrial endometrioid adenocarcinoma and one with a low-grade ovarian serous carcinoma in the setting of a serous borderline tumor. Incidental STICs in women over age 50 are uncommon. However, the significance of lesser tubal atypias (0.3% in this study), risk of STIC in women with no epithelial pathology and the risk imposed by coexisting endometrioid neoplasia are unclear and require further study.

    2001-11-01

    The clinicopathologic features of nine cases of papillary proliferation of the endometrium devoid of malignant nuclear features were studied. The patients ranged in age from 33 to 71 years (median 57 years). All were postmenopausal, except the youngest. The most common symptom was postmenopausal bleeding. Two patients were receiving hormonal replacement therapy and two were taking megestrol acetate. Two lesions were incidental findings in a hysterectomy specimen. Seven were diagnosed in endometrial biopsy or curettage specimens. In six cases (67%) the lesion involved an endometrial polyp. In all cases the papillae had fibrovascular stromal cores and variable degrees of branching. Two architectural patterns were found. A simple papillary pattern with involvement of only a few glands and little epithelial proliferation occurred in five cases, including three that were entirely intracystic. A complex papillary pattern with more extensive involvement of endometrial glands, a greater degree of branching of the papillae, and cellular tufting occurred in four cases. One or more metaplastic epithelial changes occurred in all cases, including endocervical-type mucinous metaplasia in nine cases (90%), eosinophilic cell change in eight (89%), ciliated cell change in seven (70%), focal squamous metaplasia in two cases (22%), and hobnail cell change in two (22%). Mitotic figures were found in three cases. In four lesions (44%), all with a complex papillary pattern, the proliferating cells had mild nuclear atypia. Three of these patients underwent hysterectomy within 5 months. Simple nonpapillary hyperplasia and two endometrial polyps were found in one patient, complex nonpapillary hyperplasia in one, and atrophic endometrium in the other. Two patients had additional endometrial samplings within 4 months that contained small residual simple papillary lesions. One of these had another biopsy at 16 months that showed only atrophy. One patient had no subsequent diagnostic or

    Benign papillary stenosis (BPS) is an uncommon condition, the diagnosis of which is often difficult. In this report cholescintigraphy with technetium-99m diethyl-acetanilido-iminodiacetic acid has been evaluated for the diagnosis of BPS, as well as for assessing the effect of treatment by endoscopic sphincterotomy (ES). In 12 patients with BPS, cholescintigraphy was performed before and after ES and the findings compared with those in ten controls. Time-activity curves from regions over the liver and bowel were generated. A significant difference was found in respect of the time for maximum activity (T max ) over the liver before and after ES. The time for occurrence of bowel activity (T excr ) also showed significant differences before and after ES. Considering both T max and T excr mean values plus standard deviations in the control group, all BPS patients would have been detected and there would have been no false-positives among the controls. It is concluded that cholescinitgraphy should be used in the diagnosis of BPS. The method has high sensitivity and should be applied as an early diagnostic procedure to exclude BPS in patients with clinical suspicion of the disorder. The method can also be used for assessment of endoscopic treatment (ES). (orig.)

    Full Text Available Introduction. Follicular variant (FV papillary thyroid carcinoma (PTC has aggressive biologic behavior as compared to classic variant (CV of PTC and frequently metastasizes to the lungs and bones. However, metastasis to the pancreas is extremely rare manifestation of FV-PTC. To date, only 9 cases of PTC have been reported in the literature. Pancreatic metastases from PTC usually remain asymptomatic or manifest as repeated abdominal aches. Associated obstructive jaundice is rare. Prognosis is variable with reported median survival from 16 to 46 months. Case Presentation. Herein we present a 67-year-old Saudi woman, who developed pancreatic metastases seven years after total thyroidectomy and neck dissection followed by radioactive iodine ablation (RAI for FV-PTC. Metastasectomy was performed by pancreaticoduodenectomy followed by sorafenib as genetic testing revealed a BRAF V600E mutation. She survived 32 months after the pancreatic metastasis diagnosis. Conclusion. Pancreatic metastases are rare manifestation of FV-PTC and are usually sign of extensive disease and conventional diagnostic tools may remain to reach the diagnosis.

Although after the Chernobyl accident an increase in childhood papillary thyroid cancer (PTC) was observed, it is still not clear whether the molecular biology of PTCs associated with low-dose radiation exposure differs from that of sporadic PTC. We investigated tissue samples from 65 children/young adults with PTC using DNA microarray (Affymetrix, Human Genome U133 2.0 Plus) with the aim of identifying molecular differences between radiation-induced (exposed to Chernobyl radiation, ECR) and sporadic PTC. All participants were resident in the same region so that confounding factors related to genetics or environment were minimized. There were small but significant differences in the gene expression profiles between ECR and non-ECR PTC (global test, p Chernobyl PTC are associated with previous low-dose radiation exposure.

    Objective: To explore the diagnostic value of intraductal papillary mucinous tumor (IPMT) of the pancreas, and to assess its clinical and characteristic radiological features. Methods: Thirty-six cases with IPMT who underwent CT and MRI with plain and contrast enhancement before operation were reviewed. The clinical presentation and characteristic imaging findings of main duct type (8 cases) and branch duct type (28 cases) were retrospectively reviewed. Results: Typical imaging findings of main duct type were segmental or diffuse dilation of MPD (diameter was over 9 mm) with enhanced mural nodules after contrast medium administration. MR cholangiopancreatography (MRCP) showed dilation of MPD with flat/nodule filling defects in 4 cases and MPD dilatation in the head side in 2 cases. Branch duct type was more frequently located in the head or uncinate. Typical imaging findings of branch duct type were unilocular or multilocular cystic tumors with septa, mural nodules, and MPD dilatation. MRCP showed septa in 24 cases, filling defects in 15 cases, and MPD dilatation in 8 cases. Communication between the cystic lesion and the MPD was demonstrated in 19 cases by MRCP. Conclusion: It is extremely important to accurately make the diagnosis of IPMT for planning the surgical strategy. MRCP is a noninvasive and useful method in detecting and making definite diagnosis of IPMT. (authors)

    Carcinoma arising in lingual thyroid is an extremely rare entity accounting for only 1% of all reported ectopic thyroids. Here, we report a case of carcinoma arising in lingual thyroid, which has been successfully managed by transoral resection and bilateral neck dissections. A lingual mass 4-cm in diameter with calcification was incidentally detected by computed tomography at medical check-up. No thyroid tissue was observed in normal position. Ultrasound examination showed bilateral multiple lymphadenopathies. Fine needle aspiration biopsy from lymph node in his right neck was diagnosed as Class III and thyroglobulin level of the specimen was 459ng/ml. Due to the difficulty in performing FNA of the lingual masses, right neck dissection was performed in advance for diagnostic purpose. Pathological examination showed existence of large and small follicular thyroid tissues in several lymph nodes, suggesting lymph node metastasis from thyroid carcinoma. Two months after the initial surgery, video-assisted transoral resection of lingual thyroid with simultaneous left neck dissection was performed. Postoperative course was uneventful. Papillary carcinoma was found in the lingual thyroid and thyroid tissues were also found in left cervical lymph nodes. Video-assisted transoral resection was useful for the treatment of thyroid cancer arising in lingual thyroid. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available Background. The results of video-assisted thyroidectomy (VAT were evaluated in a large series of patients with papillary thyroid carcinoma (PTC, especially in terms of completeness of the surgical resection and short-to-medium term recurrence. Methods. The medical records of all patients who underwent video-assisted thyroidectomy for PTC between June 1998 and May 2009 were reviewed. Results. Three hundred fifty-nine patients were included. One hundred twenty-six patients underwent concomitant central neck node removal. Final histology showed 285 pT1, 26 pT2, and 48 pT3 PTC. Lymph node metastases were found in 27 cases. Follow-up was completed in 315 patients. Mean postoperative serum thyroglobulin level off levothyroxine was 5.4 ng/mL. Post operative ultrasonography showed no residual thyroid tissue in all the patients. Mean post-operative 131I uptake was 1.7%. One patient developed lateral neck recurrence. No other recurrence was observed.

    Papillary thyroid carcinoma (PTC) is the most common type among thyroid cancers. The diagnosis of PTC may be challenging when follicular variant (FVPTC) of this disease is present due to the resemblance of nuclear properties of the classical type (CVPTC). However, making use of ancillary molecular markers in the diagnosis of PTC may help. In our study, we aimed to evaluate the SEPT7 protein expression in PTC. A total of 55 paraffin block tissue samples comprising encapsulated FVPTC (FVPTC(e), n=25), and CVPTC (n=15), and benign hyperfunctioning thyroid nodules (HypN, n=15) were used in this study. Nuclear, cytoplasmic, and overall (total) SEPT7 protein expression levels were determined by using immunohistochemistry. Nuclear, cytoplasmic, and overall SEPT7 expressions (p=0.02, p=0.001, p=0.002, respectively) were significantly lower in FVPTC(e) tissues when compared to HypN. In CVPTC group, nuclear expression was significantly lower (p=0.004) while overall and cytoplasmic expressions were not changed (p>0.05). In HypN group, highest nuclear (mean=2.73), cytoplasmic (mean=2.86), and overall (mean=2.86) expression scores were detected. Significantly lower SEPT7 expression in all expressional categories in FVPTC(e) group may be a sign of different molecular signature in this type of tissue. Copyright © 2014 Elsevier GmbH.

    BACKGROUND: Genome-wide association studies (GWAS) have so far reported 12 loci associated with serous epithelial ovarian cancer (EOC) risk. We hypothesized that some of these loci function through nearby transcription factor (TF) genes and that putative target genes of these TFs as identified...... in the unified microarray dataset of 489 serous EOC tumors from The Cancer Genome Atlas. Genes represented in this dataset were subsequently ranked using a gene-level test based on results for germline SNPs from a serous EOC GWAS meta-analysis (2,196 cases/4,396 controls).

    Full Text Available Abstract Background Thyroid papillary microcarcinoma (TPM is defined according to WHO criteria as a thyroid tumor smaller than 1–1.5 cm. TPMs are encountered in 0.5–35.6 % of autopsies or surgical specimens where carcinoma had been unsuspected. The purpose of the present study was to evaluate patients who had TPMs in terms of clinical findings, histopathological features and immunohistochemical evidence of expression of the tumor suppressor gene p53. Methods A total of 44 patients with TPMs less than 1.0 cm in diameter were included in the study. The patients were evaluated clinically and the tumors were evaluated in terms of their histopathological and immunohistochemical features, including expression of p53. Results The female/male ratio was 2.8/1, and the median age at time of diagnosis was 49 years (range 20–71 years. The maximum diameter of the smallest focus was 0.1 mm, and that of the largest was 10 mm microscopically. The mean diameter of all tumors was 5.7 mm. There was no correlation between tumor size and age or gender. Of the TPMs, 72 % were found in the right lobe, 24 % in the left lobe and 4 % in the isthmus. Fine-needle aspiration biopsy provided the diagnosis of TPM in only 43.2 % of the patients. All patients were treated with surgery, with 20 undergoing conservative surgery, i.e. lobectomy or isthmusectomy, and 24 undergoing total thyroidectomy. Frozen section provided the diagnosis of TPM in only 56.8 % of the patients. We found lymphocytic thyroiditis in 13.6% of patients, follicular variants in 11.9%, capsular invasion in 26.8%, lymph node involvement in 11.9%, soft tissue metastases in the neck in 12.1% and multifocality in 31.7 %, and none of these were related to age or gender (p > 0.05. No distant metastases were observed during approximately 10 years of follow up. We found p53 positivity in 34.5 % of TPM tumors. However, p53 expression was not statistically related to age or gender. Conclusion Our findings imply

    The purpose of our study was to evaluate the role of MRI in demonstrating the precise nature of papillary renal tumors (P RCC) and its potential application to select patients for partial surgery. Ninety-seven tumors less than or equal to 3 cm in size [55 papillary renal cell carcinoma - 42 clear cell renal carcinoma (CC RCC)] were preoperatively evaluated by MRI. Imaging findings were assessed with a special focus on the aspect of the tumoral process. Correlations were performed with pathologic staging after surgery. At pathology, 92 tumors were established to be staged p T1 and 5 were p T3 (3 cases of CC RCC and 2 cases of P RCC). Ninety-four percent of papillary tumors exhibited low signal intensity with homogeneous pattern on T2-weighted images. All clear cell carcinoma were hyperintense and heterogeneous on T2-weighted sequence. Enhancement was lower and delayed in the papillary type in comparison with the clear cell type. MRI is accurate enough to predict the 'histologic' nature of papillary renal carcinoma. It is an additional argument to propose that the tumor can be removed by partial surgery. (orig.)

    Full Text Available Open interdental spaces caused by papillary gingival recession are one of the most common problems faced in dentistry. Surgical and nonsurgical periodontal treatments for regeneration of lost papillary height have been reported with limited success. The present study reports effectiveness of autologous cultured fibroblast injections, a tissue engineering technique for papillary regeneration. A black triangle caused by Tarnow′s and Nordland′s class I papillary gingival loss was reported in maxillary anterior region of a young male patient. An autologous gingival biopsy was cultured in a biotechnology lab for the growth and expansion of fibroblasts. Cultured fibroblast suspension was injected into the receded papilla twice at an interval of 5 days. Follow-ups were recorded on the 6th day, 15 th day, at 1 month and at 2 months. Complete fill of black triangle was noted at the end of 2 months. No inflammatory or immune reactions were noted at the site of injection. Autologous cultured fibroblast injections are safe, efficacious, and an acceptable treatment option for the regeneration of lost papillary height.

  8. Anatomically-specific intratubular and interstitial biominerals in the human renal medullo-papillary complex.

    Full Text Available Limited information exists on the anatomically-specific early stage events leading to clinically detectable mineral aggregates in the renal papilla. In this study, quantitative multiscale correlative maps of structural, elemental and biochemical properties of whole medullo-papillary complexes from human kidneys were developed. Correlative maps of properties specific to the uriniferous and vascular tubules using high-resolution X-ray computed tomography, scanning and transmission electron microscopy, energy dispersive X-ray spectroscopy, and immunolocalization of noncollagenous proteins (NCPs along with their association with anatomy specific biominerals were obtained. Results illustrated that intratubular spherical aggregates primarily form at the proximal regions distant from the papillary tip while interstitial spherical and fibrillar aggregates are distally located near the papillary tip. Biominerals at the papillary tip were closely localized with 10 to 50 μm diameter vasa recta immunolocalized for CD31 inside the medullo-papillary complex. Abundant NCPs known to regulate bone mineralization were localized within nanoparticles, forming early pathologic mineralized regions of the complex. Based on the physical association between vascular and urothelial tubules, results from light and electron microscopy techniques suggested that these NCPs could be delivered from vasculature to prompt calcification of the interstitial regions or they might be synthesized from local vascular smooth muscle cells after transdifferentiation into osteoblast-like phenotypes. In addition, results provided insights into the plausible temporal events that link the anatomically specific intratubular mineral aggregates with the interstitial biomineralization processes within the functional unit of the kidney.

    Full Text Available Purpose: To report the cases of two patients with chronic hepatitis C infection showing serous retinal detachments similar to Vogt-Koyanagi-Harada (VKH disease. Methods: We reviewed the clinical records of two patients who were diagnosed with VKH-like disease during combined interferon-α (IFNα and ribavirin treatment. Results: Interruption of IFNα and ribavirin treatment in association with oral corticosteroids resulted in a favorable visual outcome in the case of diffuse retinal detachment (case 1. On the contrary, visual acuity did not improve when late cicatricial stage disease was already present (case 2. Conclusion: There is increasing evidence of a link between hepatitis C virus infection treated with pegylated IFNα-2b and the development of VKH-like disease. Knowing the potential side effects of IFNα and ribavirin administration is fundamentally important, as is the need to closely follow up those patients that need to undergo this treatment.

    2017-01-01

    BACKGROUND: Genome-wide association studies (GWAS) have identified 18 loci associated with serous ovarian cancer (SOC) susceptibility but the biological mechanisms driving these findings remain poorly characterised. Germline cancer risk loci may be enriched for target genes of transcription factors...... (TFs) critical to somatic tumorigenesis. METHODS: All 615 TF-target sets from the Molecular Signatures Database were evaluated using gene set enrichment analysis (GSEA) and three GWAS for SOC risk: discovery (2196 cases/4396 controls), replication (7035 cases/21 693 controls; independent from discovery...... to interact with PAX8 in the literature to the PAX8-target set and applying an alternative to GSEA, interval enrichment, further confirmed this association (P=0.006). Fifteen of the 157 genes from this expanded PAX8 pathway were near eight loci associated with SOC risk at P

    OBJECTIVE: Few studies have examined the risk of an ovarian serous borderline tumor (SBT) associated with parity, infertility, oral contraceptives (OCs), or hormone replacement therapy (HRT), which was the study aim. METHODS: This nationwide case-control study included all women with an SBT...... diagnosis in Denmark, 1978-2002. SBTs were confirmed by centralized expert pathology review. For each case, 15 age-matched female controls were randomly selected using risk-set sampling. Cases and controls with previous cancer (except for non-melanoma skin cancer) and controls with bilateral oophorectomy...... or salpingo-oophorectomy were excluded. Conditional logistic regression was used to estimate adjusted odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: We found a strongly decreased risk of SBTs among parous women which decreased with increasing number of children (p

    Full Text Available Giant (>10 cm ovarian cyst is a rare finding. In the literature, a few cases of giant ovarian cysts have been mentioned sporadically, especially in elderly patients. We report a 57-year-old postmenopausal woman with a giant left ovarian cyst measuring 43 × 15 × 9 cm. She was referred to us from the local health center in view of palpable pelvic mass for six-month period. Considering the age and menopausal state, we performed a total abdominal hysterectomy and bilateral salpingo-oophorectomy with excision of the giant left ovarian cyst intact and successfully without any significant complication. On histopathological examination, the cyst was confirmed as benign serous cystadenoma of the ovary. During the management of these high-risk cases of multidisciplinary approach, intraoperative and postoperative strict vigilance is necessary to avoid unwanted complications.

    Selective Retina Therapy (SRT) is a new and innovative laser treatment modality that selectively treats the retinal pigmentary epithelium while sparing the photoreceptors. This therapeutic concept appears to be particularly suitable for treating patients with acute or chronic central serous chorioretinopathy (CSC). We present preliminary results obtained in five patients who had CSC associated with pigmentary epithelium detachment (PED) and serous subretinal fluid (SRF) and who were treated with SRT. This case series was made up of five male patients (mean age 47 years) with chronic CSC and SRF resulting from PED. Examinations performed before and at 1 month and 3 months after the treatment were: BCVA, FLA, OCT (Zeiss OCT III). For SRT, confluent treatment of the PED (area of leakage) was carried out using a pulsed frequency-doubled, Q-switched Nd-YLF prototype laser (lambda=527 nm, t= 1.7 s, 100 Hz, energy = 150-250 J). Best corrected visual acuity at baseline was 0.53, while after 4 weeks it was 0.56 and after 12 weeks, 0.5. At baseline leakage was seen at the PED on fluorescein angiography in all patients. After 4 weeks leakage activity was no longer noted on angiography in 4 of 5 patients. OCT at baseline showed SRF at the edge of the PED in all patients, but in 4 of the 5 patients this was no longer detectable after 4 weeks. SRT is a safe and effective treatment for patients with CSC in which PED has caused SRF. Not a single case of rip syndrome was observed in this study, even though the PED was treated confluently. Since SRT spares the photoreceptors it is particularly suitable for the treatment of CSC, especially when the origin of leakage is located close to the fovea. The results indicate that SRT leads to reconstruction of the outer blood-retina barrier.

    Statins are among the most frequently prescribed drugs because of their efficacy and low toxicity in treating hypercholesterolemia. Recently, statins have been reported to inhibit the proliferative activity of cancer cells, especially those with TP53 mutations. Because TP53 mutations occur in almost all ovarian high-grade serous carcinoma (HGSC), we determined whether statins suppressed tumor growth in animal models of ovarian cancer. Two ovarian cancer mouse models were used. The first one was a genetically engineered model, mogp-TAg, in which the promoter of oviduct glycoprotein-1 was used to drive the expression of SV40 T-antigen in gynecologic tissues. These mice spontaneously developed serous tubal intraepithelial carcinomas (STICs), which are known as ovarian cancer precursor lesions. The second model was a xenograft tumor model in which human ovarian cancer cells were inoculated into immunocompromised mice. Mice in both models were treated with lovastatin, and effects on tumor growth were monitored. The molecular mechanisms underlying the antitumor effects of lovastatin were also investigated. Lovastatin significantly reduced the development of STICs in mogp-TAg mice and inhibited ovarian tumor growth in the mouse xenograft model. Knockdown of prenylation enzymes in the mevalonate pathway recapitulated the lovastatin-induced antiproliferative phenotype. Transcriptome analysis indicated that lovastatin affected the expression of genes associated with DNA replication, Rho/PLC signaling, glycolysis, and cholesterol biosynthesis pathways, suggesting that statins have pleiotropic effects on tumor cells. The above results suggest that repurposing statin drugs for ovarian cancer may provide a promising strategy to prevent and manage this devastating disease. ©2015 American Association for Cancer Research.

    The dysfunction of DNA damage repair (DDR) pathway contributes to tumorigenesis and drug-resistance in cancer. MUS81 is a member of the conserved xeroderma pigmentosum group F (XPF) family protein of endonucleases, which is important to the DDR pathway. However, the role of MUS81 in the development of ovarian cancer remains uncertain. To explore the expression of MUS81 and its association to serous ovarian cancer (SOC), 43 biopsies of SOC patients were detected by qRT-PCR, and 29 specimens were further performed by immunohistochemistry analysis. Here, we observed that MUS81 was over-expressed in SOC tissues at both transcript and protein levels, and the expression level of MUS81 protein in ovarian cancer cell lines was also higher than that in human normal ovarian surface epithelial cell line (HOSEpiC). We also found that down-regulation of MUS81 expression in ovarian cancer cells inhibited cell proliferation and colony formation ability, and influenced cell cycle progression. Moreover, inhibition of MUS81 expression induced cellular senescence and enhanced the antitumor effect of cisplatin. Down-regulation of MUS81 expression could suppress the growth and development of SOC. These results indicate that MUS81 might play important roles in the progression of SOC and influence the antitumor effect of cisplatin. - Highlights: • MUS81 was overexpression in serous ovarian cancer (SOC). • Meanwhile down-regulation of inhibited cell proliferation and influenced cell cycle progression. • Inhibition of MUS81 induced cell cellular senescence and enhanced the antitumor effect of cisplatin. • Down-regulation of MUS81 expression could suppress the growth and development of SOC.

    Full Text Available The aim of this study was to determine the prognosis and survival for patients with borderlineovarian tumor (BOT. A retrospective review of 30 patients with serous andmucinous BOT treated at or referred to our institution was performed. Fifteenpatients (50% had serous, and the others had mucinous BOT. About 86% of allpatients in both groups were in stage I of the disease. The recurrent disease occurredin 7% and 21% of serous and mucinous tumors, respectively. All recurrences,except one in mucinous tumors, were found in advance stage disease. After amean of 37 and 52 months follow-up, the overall survival was 100% and 93%, anddisease-free survival was 93% and 79% for serous and mucinous tumors,respectively. In this series, advanced stage was associated with poorprognosis. However, to obtain more accurate information further studies withnumber of patients and longer follow-up is recommended.

    We report the case of a 26-year old woman who underwent successful tricuspid valve repair for the absence of the anterior papillary of the tricuspid valve. Preoperative echocardiography revealed grade IV tricuspid valve regurgitation, caused by congenital absence of the anterior papillary muscle and prolapse of the anterior leaflet. Tricuspid valve repair was performed using artificial chords consisting of two polytetrafluoroethylene sutures and a concomitant ring annuloplasty. Postoperative echocardiography revealed mild tricuspid valve regurgitation. This approach represented a safe and effective technique for tricuspid valve repair in congenital absence of papillary muscle. © The Author 2016.

    Full Text Available Papillary thyroid carcinoma (PTC metastasis to distant organs is rare and mainly includes lung and bone. Metastasis affecting oral and maxillofacial region is extremely rare. We describe a case of PTC metastasis to cheek. The patient presented with a painless swelling of the left cheek with a history of total thyroidectomy for papillary carcinoma thyroid 5 years back. Cheek metastasis from papillary carcinoma thyroid is extremely rare. To the best of our knowledge, this is the first recorded instance of cheek metastasis from PTC. Common malignancies can metastasize to unusual sites and although infrequent, may be the presenting feature. The successful management of such cases may be achieved by a multidisciplinary approach.

    M.G.P.A. Ferreira

    Full Text Available ABSTRACT The aim of this report was to describe the clinical findings and therapeutic management of a case of papillary adenocarcinoma of the descending colon in a Beagle. The patient presented soft stools, haematochezia, tenesmus, and dyschezia. Clinical examination revealed alterations on the ultrasonographic features of the descending colon suggestive of colitis and neoplasia. Following local mass resection, histopathology analysis revealed mild lymphoplasmocytic enteritis and papillary adenocarcinoma of the colon. Enterectomy for tumoral resection and biopsy of locoregional lymph nodes were carried out. Subsequent to the surgical procedure, it was possible to confirm the previous diagnosis and the tumor was classified as intestinal intraluminal papillary adenocarcinoma, with incomplete surgical margins. Adjuvant chemotherapy was performed using carboplatin, cyclophosphamide, and piroxicam, leading to remission of clinical signs and absence of any clinical or imaging alterations compatible with the patient’s previous clinical condition.

    Full Text Available Papillary carcinoma of the breast is a rare malignant tumor, constituting 1-2 % of breast neoplasms mostly affecting elderly postmenopausal women. Intracystic (Encysted papillary carcinoma (IPC is a rare distinct entity with slow growth rate and overall favourable prognosis regardless of whether it is in situ alone or associated with invasive component. Treatment modalities vary from conservative surgery to radical surgery with or without adjuvant therapy depending upon the associated component (DCIS or invasive of the tumor. Herein, we report a case of 55-year-old female presented with a painless lump in the right breast. FNAC yielded haemorrhagic fluid with scanty cellularity of atypical ductal epithelial cells. Patient underwent wide local excision. The final histopathological diagnosis revealed intracystic papillary carcinoma associated with invasive ductal carcinoma, NOS type.

  5. HABP2 G534E Variant in Papillary Thyroid Carcinoma.

    Full Text Available The main nonmedullary form of thyroid cancer is papillary thyroid carcinoma (PTC that accounts for 80-90% of all thyroid malignancies. Only 3-10% of PTC patients have a positive family history of PTC yet the familiality is one of the highest of all cancers as measured by case control studies. A handful of genes have been implicated accounting for a small fraction of this genetic predisposition. It was therefore of considerable interest that a mutation in the HABP2 gene was recently implicated in familial PTC. The present work was undertaken to examine the extent of HABP2 variant involvement in PTC. The HABP2 G534E variant (rs7080536 was genotyped in blood DNA from 179 PTC families (one affected individual per family, 1160 sporadic PTC cases and 1395 controls. RNA expression of HABP2 was tested by qPCR in RNA extracted from tumor and normal thyroid tissue from individuals that are homozygous wild-type or heterozygous for the variant. The variant was found to be present in 6.1% familial cases, 8.0% sporadic cases (2 individuals were homozygous for the variant and 8.7% controls. The variant did not segregate with PTC in one large and 6 smaller families in which it occurred. In keeping with data from the literature and databases the expression of HABP2 was highest in the liver, much lower in 3 other tested tissues (breast, kidney, brain but not found in thyroid. Given these results showing lack of any involvement we suggest that the putative role of variant HABP2 in PTC should be carefully scrutinized.

    Following the nuclear accidents in Chernobyl and later in Fukushima, the nuclear community has been faced with important issues concerning how to search for and diagnose biological consequences of low-dose internal radiation contamination. Although after the Chernobyl accident an increase in childhood papillary thyroid cancer (PTC) was observed, it is still not clear whether the molecular biology of PTCs associated with low-dose radiation exposure differs from that of sporadic PTC. We investigated tissue samples from 65 children/young adults with PTC using DNA microarray (Affymetrix, Human Genome U133 2.0 Plus) with the aim of identifying molecular differences between radiation-induced (exposed to Chernobyl radiation, ECR) and sporadic PTC. All participants were resident in the same region so that confounding factors related to genetics or environment were minimized. There were small but significant differences in the gene expression profiles between ECR and non-ECR PTC (global test, p < 0.01), with 300 differently expressed probe sets (p < 0.001) corresponding to 239 genes. Multifactorial analysis of variance showed that besides radiation exposure history, the BRAF mutation exhibited independent effects on the PTC expression profile; the histological subset and patient age at diagnosis had negligible effects. Ten genes (PPME1, HDAC11, SOCS7, CIC, THRA, ERBB2, PPP1R9A, HDGF, RAD51AP1, and CDK1) from the 19 investigated with quantitative RT-PCR were confirmed as being associated with radiation exposure in an independent, validation set of samples. Significant, but subtle, differences in gene expression in the post-Chernobyl PTC are associated with previous low-dose radiation exposure. (orig.)

    Full Text Available BackgroundThe ultrasonographic characteristics and difference for various subtypes of papillary thyroid carcinoma (PTC are still unclear. The aim of this study was to compare the ultrasonographic features of PTC according to its subtype in patients undergoing thyroid surgery.MethodsIn total, 140 patients who underwent preoperative thyroid ultrasonography (US and thyroid surgery between January 2016 and December 2016 were included. The ultrasonographic features and the Korean Thyroid Imaging Reporting and Data System (K-TIRADS category of each thyroid nodule were retrospectively evaluated by a single radiologist, and differences in ultrasonographic features according to the PTC subtype were assessed.ResultsAccording to histopathological analyses, there were 97 classic PTCs (62.2%, 34 follicular variants (21.8%, 5 tall cell variants (3.2%, 2 oncocytic variants (1.3%, 1 Warthin-like variant (0.6%, and 1 diffuse sclerosing variant (0.6%. Most PTCs were classified under K-TIRADS category 5. Among the ultrasonographic features, the nodule margin and the presence of calcification were significantly different among the PTC subtypes. A spiculated/microlobulated margin was the most common type of margin, regardless of the PTC subtype. In particular, all tall cell variants exhibited a spiculated/microlobulated margin. The classic PTC group exhibited the highest prevalence of intranodular calcification, with microcalcification being the most common. The prevalence of multiplicity and nodal metastasis was high in the tall cell variant group.ConclusionThe majority of PTCs in the present study belonged to K-TIRADS category 5, regardless of the subtype. Our findings suggest that ultrasonographic features are not useful for distinguishing PTC subtypes.

    Benign papillary lesions of the breast include papilloma and papillomatosis. A retrospective analysis of patients with a papillary breast lesion diagnosed between October 1992 and December 2009 was performed. Patients were excluded if they had a previous or concurrent diagnosis of invasive or in situ cancer or less than 6 months of follow-up. The Kaplan-Meier method was used to determine the risk of developing subsequent malignancy. The log rank test was used to compare groups of patients. Median follow-up for the 167 patients included in the study was 4.6 years. Fifty-one patients had a papillary lesion with atypia and 116 patients had a papillary lesion without atypia. Patients with a papillary lesion with atypia were more likely to develop invasive or in situ breast cancer with a 5 year risk of 13.0% versus 4.6% in patients with no atypia (p = 0.03). © 2012 Wiley Periodicals, Inc.

  9. Clinicopathological Features and Prognosis of Papillary Thyroid Microcarcinoma for Surgery and Relationships with the BRAFV600E Mutational Status and Expression of Angiogenic Factors.

    Full Text Available To investigate the clinicopathological characteristics of papillary thyroid microcarcinoma (PTMC for surgery by comparing the difference between PTMC and larger papillary thyroid carcinoma (LPTC.We analyzed the differences in the clinicopathological characteristics, prognosis, B-type RAF kinase (BRAFV600E mutational status and expression of angiogenic factors, including pigment epithelium-derived factor (PEDF, Vascular Endothelial Growth Factor (VEGF, and hypoxia-inducible factor alpha subunit (HIF-1α, between PTMC and LPTC by retrospectively reviewing the records of 251 patients with papillary thyroid carcinoma, 169 with PTMC, and 82 with LPTC (diameter >1 cm.There were no significant differences in the gender, age, multifocality, Hashimoto's thyroiditis, TNM stage, PEDF protein expression, rate of recurrence, or mean follow-up duration between patients with PTMC or LPTC. The prevalence of extrathyroidal invasion (EI, lymph node metastasis (LNM, and BRAF mutation in patients with PTMC was significantly lower than in patients with LPTC. In addition, in PTMC patients with EI and/or LNM and/or positive BRAF (high-risk PTMC patients, the prevalence of extrathyroidal invasion, Hashimoto's disease, lymph node metastasis, tumor TNM stage, PEDF positive protein expression, the rate of recurrent disease, and the mRNA expression of anti-angiogenic factors was almost as high as in patients with larger PTC, but with no significant difference.Extrathyroid invasion, lymph node metastases, and BRAFV600E mutation were the high risk factors of PTMC. PTMC should be considered for the same treatment strategy as LPTC when any of these factors is found. Particularly, PTMC with BRAFV600E gene mutations needed earlier surgical treatment. In addition, the high cell subtype of PTMC with BRAFV600E gene mutation is recommended for total thyroidectomy in primary surgery to reduce the risk of recurrence.

    The BRAF V600E mutation is the most common genetic change in papillary thyroid carcinoma and is associated with a poorer clinical course. Usual methods for its study (DNA sequencing or molecular test based on PCR) are expensive and time-consuming. Recently, immunohistochemistry (IHC) for BRAF mutation has been introduced. To compare the results of IHC and real time PCR (RT-PCR) in the detection of BRAF V600E mutation in papillary thyroid carcinoma. Analysis of clinical and pathological differences depending on RT-PCR results is included. A prospective study was performed in 82 consecutive samples, 54 of them taken through a core needle biopsy. IHC was performed on tissue fixed for 24hours with 10% neutral formalin using the anti-BRAF V600E (VE-1) mouse monoclonal primary antibody and was rated as positive or negative. DNA was extracted from formalin-fixed, paraffin-embedded tissues by manual microdissection, and BRAF mutation was detected by RT-PCR using the Cobas® 4800 BRAF V600 mutation test (Roche). Both techniques were concordant in 81 cases, and BRAF was positive in 49. Discordance appeared in a follicular variant showing positive IHC and negative RT-PCR, attributed to histological heterogeneity. Cost of materials for IHC was less than half of the cost for RT-PCR. IHC appears to be a reliable, economical and easily available alternative to molecular biology techniques for routine detection of the BRAF V600E mutation in papillary thyroid carcinoma patients, provided optimal fixation conditions are used. It may be a useful technique in hospitals with no access to molecular biology techniques. Copyright © 2017 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.

    Former studies suggest the frequent coexistence of Hashimoto's thyreoditis with papillary thyroid cancer, frequently featured by multifocal carcinogenesis but lower clinical stages compared to thyroid cancers lacking thyroiditis. We examined the clinico-pathological correlations between Hashimoto's thyroditis and papillary thyroid cancer in our region in the North-Eastern part of Hungary. We included a total of 230 patients with papillary thyroid cancer who underwent thyroid surgery at the Surgical Department of the University of Debrecen. Patients' sex, age, multifocality of thyroid cancer and clinical stage were evaluated. Cases included 40 patients (17.4%) with (4 male, 36 female) and 190 (82.6%) patients without HT (44 male, 146 female). Hashimoto's thyroiditis related thyroid cancer was almost exclusively associated with the papillary histological type. Multifocality of papillary cancer was significantly more frequent with coexisting Hashimoto's thyroiditis (16/40; 40.0%) compared to cases uninvolved (45/190; 23.7%; p = 0.034). In contrast, lymph node metastasis was significantly less frequent among patients with Hashimoto's thyroiditis (4 pN1 [36.4%]; 7 pN0 [63.6%]) then without it (34 pN1 [82.9%]; 7 pN0 [17.1%]; p = 0.002). Higher frequency and multifocality of papillary thyroid cancer might be the consequence of preexisting Hashimoto's thyroiditis to be considered as a preneoplastic stimulus supporting carcinogenesis, though the exact pathomechanism of this correlation is not clear yet.

    Full Text Available Endotracheal metastasis is a rare situation, usually associated with malignancies of breast and gastrointestinal tract, specially colon. Papillary carcinoma of thyroid commonly disseminates through lymphatic channels and tracheal involvement through vascular route is rarely reported. Here, we report a case of tracheal metastasis from papillary carcinoma of thyroid. The patient responded to external beam radiation therapy with cobalt 60 beams in a dose of 44 Gy followed by a 16 Gy boost. The patient is under followup and is presently asymptomatic. This paper adds to the repertoire of evidence in treatment of endotracheal metastasis.

    Full Text Available We herein describe a case showing eccrine syringofibroadenoma occurred on the dorsum of the right foot of a 46-year-old Japanese female. Histopathologic examination revealed anastomosing cords and strands of cuboidal epithelial cells extending from the epidermis to the upper dermis, with a number of well-defined ducts suggesting eccrine ductal origin. In addition, there were papillary tubular adenoma-like ductal structures lined by a few rows of epithelial cells with papillary projections into the lumen surrounded by fibrous stroma in the mid-dermis. It is of note that various histologic features showing different differentiation were seen in a single lesion of eccrine syringofibroadenoma.

    Craniopharyngiomas are histologically benign but locally aggressive tumors in the sellar region that may cause devastating neurological and endocrine deficits. They tend to recur following surgery with high morbidity; hence, postoperative radiotherapy is recommended following sub-total resection. BRAFV600E mutation is the principal oncogenic driver in the papillary variant of craniopharyngiomas. Recently, a dramatic tumor reduction has been reported in a patient with BRAFV600E mutated, multiply recurrent papillary craniopharyngioma using a combination therapy of BRAF inhibitor dabrafenib and MEK inhibitor trametinib. Here, we report on near-radical reduction of a growing residual BRAFV600E craniopharyngioma using the same neoadjuvant therapy.

    Full Text Available Invasive papillary carcinoma of the breast is a rare, distinct variant comprising approximately less than 1-2% of all newly diagnosed cases of breast carcinoma and is usually found in postmenopausal women with a more favorable prognosis. We report an unusual case in a 45-year-old perimenopausal female who came with a complaint of lump in right breast for duration of 1 year. A simple mastectomy was undertaken for histopathological study and immunohistochemistry (IHC which showed characteristic features of an invasive papillary breast carcinoma. We present this case in view of its rarity and to highlight this clinicopathological subtype for its good prognosis and to avoid overtreatment.

    Full Text Available Papillary ependymoma is a rare tumor that may be located along the ventricular walls or within the spinal cord. We report the case of a 54-year-old patient with a papillary ependymoma WHO grade II arising at the entrance of the aqueduct. The tumor caused hydrocephalus. The tumor was completely removed via a right-sided endoscopic approach with restoration of the aqueduct. The free cerebrospinal fluid passage through the aqueduct was not only visualized by endoscopy but also controlled by intraoperative high-field magnetic resonance imaging. Therefore, an additional endoscopic third ventriculostomy was unneccessary.

    The case of a 67-year-old man is presented. He was admitted for the presence of a left parietal tumour with progressive growing, without any other objective or subjective symptomatology. CT-scan detects a left parietal osteolytic area. The histopathological aspect suggested an adenocarcinomatous metastasis with papillary pattern, moderately differentiated. With the purpose of diagnosing the original tumour, immunnohistochemical techniques were performed, which led to a diagnosis of a thyroidian carcinoma. At the histological examination of the surgical extirpated thyroid, it was proved to be a papillary carcinoma (Chan, 1990, Hay, 1990), the follicular pattern.

  2. Increased intragenic IGF2 methylation is associated with repression of insulator activity and elevated expression in serous ovarian carcinoma

    Zhiqing eHuang

    2013-05-01

    Full Text Available Overexpression of insulin-like growth factor-II (IGF2 is a prominent characteristic of many epithelial ovarian malignancies. IGF2 imprinting and transcription are regulated in part through DNA methylation, which in turn regulates binding of the insulator protein, CTCF, within the IGF2/H19 imprint center. We have shown that IGF2 overexpression in ovarian cancer is associated with hypermethylation of CTCF binding sites within the IGF2/H19 imprint center. The aim of this study was to investigate the methylation and binding capacity of a novel putative CTCF binding motif located intragenic to IGF2 and determine how this relates to IGF2 expression. In 35 primary serous epithelial ovarian cancer specimens, methylation of two CpGs, including one within the core binding motif and another adjacent to this motif, was higher in the 18 cancers with elevated IGF2 expression versus 10 with low expression (avg. 68.2% vs. 38.5%; p<0.0001. We also found that the CpG site within the CTCF binding motif is hypermethylated in male gametes (>92%; avg. 93.2%; N=16. We confirmed binding of CTCF to this region in ovarian cancer cells, as well as the paralog of CTCF, BORIS, which is frequently overexpressed in cancers. The unmethylated CTCF binding motif has insulator activity in cells that express CTCF or BORIS, but not in cells that express both CTCF and BORIS. These intragenic CpG dinucleotides comprise a novel paternal germline imprint mark and are located in a binding motif for the insulator protein CTCF. Methylation of the CpG dinucleotides is positively correlated with IGF2 transcription, supporting that increased methylation represses insulator function. These combined results suggest that methylation and CTCF binding at this region play important roles in regulating the level of IGF2 transcription. Our data have revealed a novel epigenetic regulatory element within the IGF2/H19 imprinted domain that is highly relevant to aberrant IGF2 expression in ovarian

    As part of a continuing investigation of the comparative ultrastructure of chiropteran salivary glands, we examined the submandibular glands of eight species of neotropical fruit bats in the genus Artibeus. We previously described secretory granules of unusual substructure in the seromucous demilunar cells of this organ in some species in this genus. In the present study, we turned our attention to the serous acinar cells in the same glands. Specimens of eight species of Artibeus were collected in neotropical localities. Salivary glands were extirpated in the field and thin slices were fixed by immersion in triple aldehyde-DMSO or in modified half-strength Karnovsky's fixative. Tissues were further processed for electron microscopy by conventional means. In contrast to seromucous cells, which exhibit species-specific diversification in bats of this genus, the secretory apparatus and secretory granules in the serous acinar cells are highly conserved across all seven species. The single exception involves the mitochondria in one species. In this instance, some of the serous cell mitochondria in Artibeus obscurus are modified into megamitochondria. Such organelles usually have short, peripheral cristae; a laminar inclusion is present in the matrix compartment of every outsized organelle. Inclusions of this nature never are present in normal-size mitochondria in the serous cells. None of the megamitochondria were observed in the process of degeneration. The giant mitochondria in A. obscurus have a matrical structure that is radically different from that of the only other megamitochondria reported to occur in bat salivary glands. The factors that lead to variation in megamitochondrial substructure in different species, as well as the functional capacities of such giant organelles, are unknown.

  4. Biotinidase is a novel marker for papillary thyroid cancer aggressiveness.

    Anthony K-C So

    Full Text Available Biotinidase was identified in secretome analysis of thyroid cancer cell lines using proteomics. The goal of the current study was to analyze the expression of biotinidase in thyroid cancer tissues and fine needle aspiration (FNA samples to evaluate its diagnostic and prognostic potential in thyroid cancer. Immunohistochemical analysis of biotinidase was carried out in 129 papillary thyroid cancer (PTC, 34 benign thyroid tissues and 43 FNA samples and correlated with patients' prognosis. Overall biotinidase expression was decreased in PTC compared to benign nodules (p = 0.001. Comparison of aggressive and non-aggressive PTC showed decrease in overall biotinidase expression in the former (p = 0.001. Loss of overall biotinidase expression was associated with poor disease free survival (p = 0.019, Hazards ratio (HR = 3.1. We examined the effect of subcellular compartmentalization of nuclear and cytoplasmic biotinidase on patient survival. Decreased nuclear expression of biotinidase was observed in PTC as compared to benign tissues (p<0.001. Upon stratification within PTC, nuclear expression was reduced in aggressive as compared to non-aggressive tumors (p<0.001. Kaplan-Meier survival analysis showed significant association of loss of nuclear biotinidase expression with reduced disease free survival (p = 0.014, HR = 5.4. Cytoplasmic biotinidase expression was reduced in aggressive thyroid cancers in comparison with non-aggressive tumors (p = 0.002, Odds ratio (OR = 0.29 which was evident by its significant association with advanced T stage (p = 0.003, OR = 0.28, nodal metastasis (p<0.001, OR = 0.16, advanced TNM stage (p<0.001, OR = 0.21 and extrathyroidal extension (p = 0.001, OR = 0.23.

    Objective: To investigate the CT and MRI features of intraductal papillary neoplasm of the bile duct (IPNB). Methods: Thirty eight patients with IPNB finally diagnosed by puncture biopsy or surgery were enrolled in this study. All the CT or MRI data were investigated retrospectively. Twenty one patients underwent CT examinations, 17 patients underwent MRI examinations. The features of IPNB including the distribution features of the nodules or masses, CT and MRI features of cholangiectasis, mucus were analyzed. The accuracy differences of CT and MRI for the preoperatively diagnosing mucus and tumor growing along mucous were compared by nonparametric test. Results: The lesions (including 5 patients with solitary lesions and 19 patients with multiple lesions) were located in intrahepatic bile duct in 24 patients, 3 patients occurred simultaneously in intrahepatic and portal bile duct, 2 lesions occurred in portal bile duct, 8 lesions occurred in common bile duct, the lesions of 1 patient occurred simultaneously in common bile duct, cystic duct and gallbladder. Seventeen and 11 patients appeared nodules locating in dilated bile duct on CT and MRI, respectively. Four and 5 patients appeared cystic lesions with multiple nodules of the liver on CT and MRI, respectively. Higher contrast enhancement on CT and MRI in arterial phase than that in portal vein and equilibrium phase were observed in 18 and 12 patients, respectively. Excluding the patients undergoing puncture, CT was better than MRI in evaluating whether the mucus was present, with the accuracies of 30.0% (6/20) and 6.3% (1/16) for CT and MRI, respectively (Z=2.58, P<0.05). CT was worse than MRI in preoperatively evaluating the features of tumor growing along mucous, with the accuracies of 77.8% (14/18) and 92.6% (13/14) for CT and MRI, respectively (Z=4.23, P<0.01). Conclusion: IPNB had the features of growing along mucous of the bile duct, nodule or mass in dilated bile duct and other features, CT and MRI are

    Although named "ovarian cancer," it has been unclear whether the cancer actually arises from the ovary, especially for high-grade serous carcinoma (HGSC), also known as high-grade serous ovarian cancer, the most common and deadliest ovarian cancer. In addition, the tumor suppressor p53 is the most frequently mutated gene in HGSC. However, whether mutated p53 can cause HGSC remains unknown. In this study, we bred a p53 mutation, p53(R172H), into conditional Dicer-Pten double-knockout (DKO) mice, a mouse model duplicating human HGSC, to generate triple-mutant (TKO) mice. Like DKO mice, these TKO mice develop metastatic HGSCs originating from the fallopian tube. Unlike DKO mice, however, even after fallopian tubes are removed in TKO mice, ovaries alone can develop metastatic HGSCs, indicating that a p53 mutation can drive HGSC arising from the ovary. To confirm this, we generated p53(R172H)-Pten double-mutant mice, one of the genetic control lines for TKO mice. As anticipated, these double-mutant mice also develop metastatic HGSCs from the ovary, verifying the HGSC-forming ability of ovaries with a p53 mutation. Our study therefore shows that ovaries harboring a p53 mutation, as well as fallopian tubes, can be a distinct tissue source of high-grade serous ovarian cancer in mice.

Recurrence of the disease in early stage (FIGO-stages I-II serous ovarian cancer results in survival that is comparable to those with recurrent advanced-stage disease. The aim of this study was to investigate if there are specific genomic aberrations that may explain recurrence and clinical outcome. Methods Fifty-one women with early stage serous ovarian cancer were included in the study. DNA was extracted from formalin fixed samples containing tumor cells from ovarian tumors. Tumor samples from thirty-seven patients were analysed for allele-specific copy numbers using OncoScan single nucleotide polymorphism arrays from Affymetrix and the bioinformatic tool Tumor Aberration Prediction Suite. Genomic gains, losses, and loss-of-heterozygosity that associated with recurrent disease were identified. Results The most significant differences (p  Conclusions The results of our study indicate that presence of two aberrations in TP53 on 17p and LOH on 19q in early stage serous ovarian cancer is associated with recurrent disease. Further studies related to the findings of chromosomes 17 and 19 are needed to elucidate the molecular mechanism behind the recurring genomic aberrations and the poor clinical outcome.

    Data from 576 patients with papillary thyroid cancer were retrospectively analyzed. With a median follow-up of 10 years and three months, there were six deaths from, and 84 recurrences of, thyroid cancer. Of the latter, 16 (19 percent) could not be eradicated. Death from thyroid cancer occurred only in those 30 years of age or over at the time of diagnosis and only in patients with primary tumors larger than 1.5 cm in diameter. Locally invasive tumor was associated with a poor prognosis. Cervical lymph node metastases found at initial surgery were associated with higher recurrence rates but not higher mortality rates. Treatment with total thyroidectomy, postoperative radioiodine and thyroid hormone resulted in the lowest recurrence and mortality rates except in those patients with small primary tumors (less than 1.5 cm diameter) in whom less than total thyroidectomy and postoperative therapy with thyroid hormone alone gave results which did not differ statistically from those achieved with more aggressive therapy. No important differences in outcome were observed when cervical lymph node metastases were simply excised or more aggressively treated by neck dissection. External radiation and as initial adjunctive therapy adversely influenced outcome

    Central serous chorioretinopathy (CSC) is a disease in which serous detachment of the neurosensory retina occurs over an area of leakage from the choriocapillaris through the retinal pigment epithelium. Associations have been drawn between high-stress personality types and steroid exposure. This article aims to describe a unique case series of two husband and wife couples with CSC. All methods were approved by the authors' institution's institutional review board. History, physical examination, and imaging data were obtained from the electronic medical records of the patients in question and from the providers who cared for these patients. Couple 1: A 35-year-old man presented with "dark spots" in his right eye. He reported no recent steroid use. Visual acuity at presentation was 20/30 in the right eye and 20/20 in the left eye. On fundus examination, there was subretinal fluid in the right eye. His wife presented on the same day with a "wavy section" in the right eye for 6 weeks. She also had no recent steroid use. Visual acuity at presentation was 20/20 in both eyes with blunting of the foveal reflex in the right eye. Optical coherence tomography showed a thick choroid with a pigment epithelial detachment in the right eye. Couple 2: A 34-year-old man presented with "blurry vision" in his right eye for one month. He was taking oral and nasal steroids for chronic sinusitis. Visual acuity was 20/30 in the right eye and 20/20 in the left eye. Fluorescein angiography and indocyanine green confirmed the diagnosis of CSC. After 3 months of persistent subretinal fluid, he received photodynamic therapy in the right eye. Three days after his photodynamic therapy, his 38-year-old wife presented with subjective blurring in both eyes. Visual acuity was 20/20 in both eyes, but optical coherence tomography showed thick choroid in both eyes, a large central pigment epithelial detachment in the right eye, and 3 small pigment epithelial detachments in the left eye. She had no

Methods: This was a retrospective analysis of eight patients with chronic CSC unresponsive to topical nonsteroidal anti-inflammatory drugs, focal photocoagulation, anti-VEGF alone, or PDT alone. All patients were evaluated with a full ophthalmic examination, spectral-domain optical coherence tomography (OCT, fluorescein angiography (FA, and most with indocyanine green angiography (ICGA followed by treatment with half-fluence PDT and intravitreal anti-VEGF injection (seven bevacizumab, one aflibercept. Patients were seen in follow-up 1 month after treatment. Results: All eight patients achieved complete resolution in subretinal fluid following combination treatment. Average duration of CSC prior to initiation of combination therapy was 7.5 months. Mean central macular thickness on OCT decreased significantly from 401.2±52.7 µm to 297.9±18.2 µm (p=0.0010 by 4 months after treatment (1.63±1.18 months. Seven of eight patients were followed up for an average of 13 months with no recurrence during that time. One case recurred at 8 months and was treated with repeat combination at that time. Frank choroidal neovascularization (CNV was not identified in these cases on FA or ICGA studies. Eight of eight patients showed significant improvement in vision from a logMAR of 0.1125±0.099 to 0.0125±0.064 (p=0.019. Conclusion: Combination PDT and anti-VEGF is effective for chronic CSC which has failed conventional therapy. Associated CNV and/or inflammation may be reasons for greater success in

    There is mounting evidence that serous tubal intraepithelial carcinoma (STIC) may be the immediate precursor of ovarian high-grade serous carcinoma (HGSC) but the criteria for its diagnosis are not well established as highlighted in a recent study showing that interobserver reproducibility, even among expert gynecologic pathologists, was moderate at best. Given the clinical significance of a diagnosis of STIC in a patient who has no other evidence of ovarian carcinoma, this is a serious issue that we felt needed to be addressed. Although it is not clear, at this time, whether such a patient should or should not be treated, the importance of an accurate and reproducible diagnosis of precursors of ovarian carcinoma cannot be underestimated. We hypothesized that an elevated Ki-67 labeling index may aid the diagnosis of STIC. Accordingly, we compared the Ki-67 index of STIC and HGSC to normal fallopian tube epithelium (FTE) in the same patients and to a control group of patients without carcinoma, matched for age. A total of 41 STICs were analyzed, of which 35 were associated with a concurrent HGSC. In FTE, immunoreactivity for Ki-67 was restricted to a few scattered cells (mean 2.0%). No statistically significant difference was found between patients with and without HGSC (P>0.05). However, both STICs and HGSC had significantly higher Ki-67 indices than normal FTE (PSTICs uniformly had an elevated Ki-67 labeling index that ranged from 11.7% to 71.1% (average 35.6%). There was no correlation of the Ki-67 labeling index in the STICs and the associated HGSC, as the labeling index was lower in STIC in 18/35 (51.4%) whereas it was higher in 17/35 (48.6%) (P=0.86). In conclusion, the findings in this study indicate that compared with FTE, STICs have a significantly higher Ki-67 index similar to HGSC. Accordingly, the Ki-67 index can aid the diagnosis of intraepithelial tubal proliferations suspicious for STIC. Therefore, we propose that a Ki-67 index of 10% is a useful

    The reduced expression of the Adenomatous polyposis coli (APC) gene, a tumor suppressor gene, through promoter hypermethylation has been reported to play a key role in the carcinogenesis. However, the correlation between APC promoter hypermethylation and ovarian cancer (OC) remains to be clarified. A comprehensive literature search was carried out in related research databases. The overall odds ratio (OR) and corresponding 95 % confidence interval (CI) were used to evaluate the effects of APC promoter hypermethylation on OC and clinicopathological characteristics. Ultimately, 12 eligible studies were used in our study, including 806 OC samples, 429 normal controls, 109 benign lesions and 75 LMP samples. The pooled OR showed that APC promoter hypermethylation was significantly higher in OC than in normal and benign controls (OR = 6.18 and OR = 3.26, respectively). No significant correlation was observed between OC and low malignant potential (LMP) tumors (P = 0.436). In the comparison of OC and normal controls, subgroup analysis based on race showed that the overall OR of APC promoter hypermethylation was significant and similar in Asians and Caucasians (OR = 8.34 and OR = 5.39, respectively). A subgroup analysis based on sample type found that the pooled OR was significantly higher in blood than in tissue (OR = 18.71 and OR = 5.74, respectively). A significant association was not observed between APC promoter hypermethylation and tumor grade or tumor stage. The pooled OR indicated that APC promoter hypermethylation was significantly lower in serous carcinoma than in non-serous carcinoma (OR = 0.56, P = 0.02). No obvious publication bias was detected by Egger's test (all P > 0.05). APC promoter hypermethylation may be linked to the increased risk of OC. It was associated with histological type, but not with tumor grade or tumor stage. Moreover, hypermethylated APC may be a noninvasive biomarker using blood samples. Future

    To study the clinicopathological characteristics of papillary cystadenoma of the epididymis. Using routine pathology and immunohistochemistry, we observed the surgically obtained samples from 2 cases of papillary cystadenoma of the epididymis, analyzed their pathological features and clinical presentations, and reviewed the related literature. The 2 patients were both adult males. The tumors typically manifested as painless swelling in the epididymis, with occasionally dull pain and tenesmus in 1 of the cases. Pathologically, the lesions exhibited three morphological features, i. e., dilated ducts and small cysts surrounded by fibrous connective tissue, adenoid papillary hyperplasia into the cysts embraced by fibrovascular stroma, and acidophil substance present in the cysts. Immunohistochemistry showed that the tumors were strongly positive for CK8/18, CK7, and EMA, but negative for CK20, CEA, MC, Calretenin, P53, P63, SMA, VHL, and CD10, with the positive rate of Ki-67 <1%. Follow-up visits revealed good prognosis in both cases. Papillary cystadenoma of the epididymis is a rare benign tumor in the male urogenital system, which may be accompanied by the VHL syndrome. Surgery is the first choice for its treatment.

    Uroplakins are differentiation-related membrane proteins of urothelium. We compared uroplakin expression and ultrastructural localization in human normal urothelium, papilloma and papillary carcinoma. Because of high recurrence rate of these tumours, treated by transurethral resection, we investigated urothelial tumour, resection border and uninvolved urothelium. Urinary bladder samples were obtained from tumour free control subjects and patients with papilloma and papillary carcinoma. Immunohistochemical and immunoelectron labelling of uroplakins were performed. In normal human urothelium with continuous uroplakin-positive superficial cell layer uroplakins were localized to flattened mature fusiform vesicles and apical plasma membrane of umbrella cells. Diverse uroplakin expression was found in papilloma and papillary carcinoma. Three aberrant differentiation stages of urothelial cells, not found in normal urothelium, were recognized in tumours. Diverse uroplakin expression and aberrant differentiation were occasionally found in resection border and in uninvolved urothelium. We demonstrated here that uroplakin expression and localization in urothelial tumours is altered when compared to normal urothelium. In patients with papilloma and papillary carcinoma immunolabelling of uroplakins at ultrastructural level shows aberrant urothelial differentiation. It is possible that aberrant differentiation stages of urothelial cells in resection border and in uninvolved urothelium contribute to high recurrence rate

    This study aimed to examine atypical and malignant papillary oral lesions for low- and high-risk human papillomavirus (HPV) infection and to correlate HPV infection with clinical and pathologic features. Sections of 28 atypical papillary lesions (APLs) and 14 malignant papillary lesions (MPLs) were examined for HPV by in situ hybridization and for p16 and MIB-1 by immunohistochemistry; 24 conventional papillomas were studied for comparison. Low-risk HPV was found in 10 of 66 cases, including 9 APLs and 1 papilloma. All low-risk HPV-positive cases showed suprabasilar MIB-1 staining, and the agreement was statistically significant (P < .0001). Diffuse p16 staining combined with high-risk HPV was not seen in any of the cases. A subset of HPV(-) APLs progressed to carcinoma. Oral papillary lesions are a heterogeneous group. Low-risk HPV infection is associated with a subset of APLs with a benign clinical course. Potentially malignant APLs and MPLs are not associated with low- or high-risk HPV.

    Full Text Available Introduction. Papillary squamotransitional cell carcinoma (PSTCC is an uncommon histopathological variant of squamous cell carcinoma (SCC of the uterine cervix, which occurs in postmenopausal women. Presentation of Case. Herein, we describe a case of a 63-year-old woman who presented with 4-month history of postmenopausal vaginal bleeding. Vaginal examination revealed a fragile lesion of size 1×1 cm invading left posterior vaginal fornice and parametrium. Biopsy showed the presence of papillae containing fibrovascular cores lined by multilayered atypical epithelial cells resembling squamous and transitional cell epithelium, confirming the diagnosis of PSTCC of the uterine cervix. After staging work-up she was staged according to the International Federation of Gynecology and Obstetrics (FIGO staging system 2009 as FIGO IIB, and she was started on extended field concurrent chemoradiation. Discussion. PSTCC of the uterine cervix is an extremely rare and aggressive entity. PSTCC is often characterized by the presence of papillary structures with prominent fibrovascular cores. PSTCC of the uterine cervix should be differentiated from transitional cell carcinoma, squamous papilloma, papillary adenocarcinoma, and cervical intraepithelial neoplasia with papillary features. Conclusion. PSTCC of the uterine cervix is a diagnostic challenge; further studies regarding the mechanism underlying the development of PSCC are warranted.

    Activating mutations of GNAq protein in a hotspot at codon 209 have been recently described in uveal melanomas. Since these neoplasms share with thyroid carcinomas a high frequency of MAP kinase pathway-activating mutations, we hypothesized whether GNAq mutations could also play a role in the development of thyroid carcinomas. Additionally, activating mutations of another subtype of G protein (GNAS1) are frequently found in hyperfunctioning thyroid adenomas, making it plausible that GNAq-activating mutations could also be found in some of these nodules. To investigate thyroid papillary carcinomas and thyroid hyperfunctioning nodules for GNAq mutations in exon 5, codon 209, a total of 32 RET/PTC, BRAF, and RAS negative thyroid papillary carcinomas and 13 hyperfunctioning thyroid nodules were evaluated. No mutations were identified. Although plausible, GNAq mutations seem not to play an important role in the development of thyroid follicular neoplasms, either benign hyperfunctioning nodules or malignant papillary carcinomas. Our results are in accordance with the literature, in which no GNAq hotspot mutations were found in thyroid papillary carcinomas, as well as in an extensive panel of other tumors. The molecular basis for MAP-kinase pathway activation in RET-PTC/BRAF/RAS negative thyroid carcinomas remains to be determined.

    Purpose: Papillary carcinoma is the most frequent type of thyroid cancer and was considered the most benign of all thyroid carcinomas, with a low risk of distant metastases. However, there are some variants of papillary thyroid carcinoma that have affinity to spread in many organs, such as: lymph nodes, lungs and bones. Aim: The aim of this study was presentation of a case with papillary carcinoma of the thyroid gland, very persistent and resistant in treatment with I 131. Material and results: A man 56 years old were diagnosed with papillary carcinoma of thyroid gland. He underwent a surgical removal of the tumor and right lobe of thyroid gland. With histopathology examination, were confirmed follicular variant of papillary carcinoma pT4. Two weeks later he underwent total thyroidectomy and was treated with 100 mCi of J 131. Six months later, the value of thyroglobulin was found elevated above upper measured limits (more than 500 ng/ml). Patient underwent surgical removal of 10 metastatic lymph nodes in the left side of the neck and has been treated with 145 mCi of radioiodine I 131. The examination after 5 months shows elevation of thyroglobulin, more than 20000 ng/ml and focally uptake of J 131 in the left lung. Patient was treated once again with 150 mCi radioiodine J 131. Whole body scintigraphy was registered focal uptake of radioiodine in the middle of the left collarbone. After a month, patient refers the enlargement of the lymph node in the right side of the neck. Currently patient is being treated with kinase inhibitor drug sorafenib and ibandronate. We have identified first positive response in treatment. Enlarged lymph node in the neck was reduced and the patient began feeling better. Conclusion: This study suggests that some subtypes of papillary thyroid carcinoma appear to have more aggressive biological course. Subtypes of papillary thyroid carcinoma such as diffuse sclerosing carcinoma, tall cell or columnar cell and insular variants, appears to

    Although it is known that the papillary muscles ensure the continuity between the left ventricle (LV) and the mitral apparatus, their precise mechanism needs further study. We hypothesize that the papillary muscles function as shock absorbers to maintain a constant distance between their tips and the mitral annulus during the entire cardiac cycle. Sonomicrometry crystals were implanted in five sheep in the mitral annulus at the trigones (T1 and T2), mid anterior annulus (AA) mid posterior annulus (PA), base of the posterior lateral scallops (P1 and P2), tips of papillary muscles (M1 and M2), and LV apex. LV and aortic pressures were simultaneously recorded and used to define the different phases of the cardiac cycle. No significant distance changes were found during the cardiac cycle between each papillary muscle tip and their corresponding mitral hemi-annulus: M1-T1, (3.5+/-2%); M1-P1 (5+/-2%); M1-PA (5+/-3%); M2-T2 (2.7+/-2%); M2-P2 (6.1+/-3%); and M2-AA (4.2+/-3%); (p>0.05, ANOVA). Significant changes were observed in distances between each papillary muscle tip and the contralateral hemi-mitral annulus: M1-T2 (1.7+/-3%); M1-P2 (23+/-6%); M1-AA (6+/-3%); M2-T1 (8+/-3%); M2-P1 (10.5+/-6%); and M2-PA (12.6+/-8%); (pshock absorbers to maintain the basic mitral valve geometry constant during the cardiac cycle.

    To report variable radiologic manifestastions and to accomplish detailed radiologic-pathologic correlation of solid and papillary epithelial neoplasm of the pancreas. In 23 patients with surgically confirmed solid and papillary epithelial neoplasm, retrospective examination of operative records, gross and micropathologic findings, and radiologic findings including US(n=17), CT(n=23), ERCP(n=9), MRI(n=3) were carried out. On the basis of pathologic findings, detailed analysis of radiologic findings of solid and papillary epithelial neoplasm was then performed. Most pancreatic solid and papillary epithelial neoplasms(n=17) were seen as a mass with heterogeneous internal density consisting of cystic change, hemorrhagic necrosis, and tumor tissue, although the mass con also be seen to be homogeneous(n=6). On gross specimens, a capsule which showed enhancement on the delayed phase of the enhanced CT scan was demonstrated in 22 cases. In was seen as an echogenic rim on the ultrasound images and a low signal rim on the MR images. Calcification of the mass was seen in ten cases, nine of which showed peripheral calcification along the tumor capsule ; five cases showed calcifications within the mass. On pathologic examination, ten cases had a single or multiple cystic appearance ; in seven of these cases, this appeared on CT scan. In addition to usual mixed internal density caused by hemorrhagic necrosis of the tumor, enhanced capsule and internal multicystic appearance on CT scan were other characteristics of pancreatic solid and papillary epithelial neoplasm. These could be useful findings in the radiologic approach and in the differential diagnosis of pancreatic masses

    Full Text Available Background Warthin-like variant of papillary thyroid carcinoma (WLV-PTC is a relatively rare variant of papillary thyroid carcinoma with favorable prognosis. However, preoperative diagnosis using fine-needle aspiration (FNA specimens is challenging especially with lymphocytic thyroiditis characterized by Hürthle cells and lymphocytic background. To determine a helpful cytological differential point, we compared WLV-PTC FNA findings with conventional papillary thyroid carcinoma with lymphocytic thyroiditis (PTC-LT and conventional papillary thyroid carcinoma without lymphocytic thyroiditis (PTC regarding infiltrating inflammatory cells and their distribution. Preoperative diagnosis or potential for WLV-PTC will be helpful for surgeons to decide the scope of operation. Methods Of the 8,179 patients treated for papillary thyroid carcinoma between January 2007 and December 2012, 16 patients (0.2% were pathologically confirmed as WLV-PTC and four cases were available for cytologic review. For comparison, we randomly selected six PTC-LT cases and five PTC cases during the same period. The number of intratumoral and background lymphocytes, histiocytes, neutrophils, and the presence of giant cells were evaluated and compared using conventional smear and ThinPrep preparations. Results WLV-PTC showed extensive lymphocytic smear with incorporation of thyroid follicular tumor cell clusters and frequent histiocytes. WLV-PTC was associated with higher intratumoral and background lymphocytes and histiocytes compared with PTC-LT or PTC. The difference was more distinct in liquid-based cytology. Conclusions The lymphocytic smear pattern and the number of inflammatory cells of WLV-PTC are different from those of PTC-LT or PTC and will be helpful for the differential diagnosis of WLV-PTC in preoperative FNA.

    Full Text Available Overall survival for patients with ovarian cancer (OC has shown little improvement for decades meaning new therapeutic options are critical. OC comprises multiple histological subtypes, of which the most common and aggressive subtype is high-grade serous ovarian cancer (HGSOC. HGSOC is characterized by genomic structural variations with relatively few recurrent somatic mutations or dominantly acting oncogenes that can be targeted for the development of novel therapies. However, deregulation of pathways controlling homologous recombination (HR and ribosome biogenesis has been observed in a high proportion of HGSOC, raising the possibility that targeting these basic cellular processes may provide improved patient outcomes. The poly (ADP-ribose polymerase (PARP inhibitor olaparib has been approved to treat women with defects in HR due to germline BRCA mutations. Recent evidence demonstrated the efficacy of targeting ribosome biogenesis with the specific inhibitor of ribosomal RNA synthesis, CX-5461 in v-myc avian myelocytomatosis viral oncogene homolog (MYC-driven haematological and prostate cancers. CX-5461 has now progressed to a phase I clinical trial in patients with haematological malignancies and phase I/II trial in breast cancer. Here we review the currently available targeted therapies for HGSOC and discuss the potential of targeting ribosome biogenesis as a novel therapeutic approach against HGSOC.

    Uterine serous cancer (USC) is aggressive, and the majority of recurrent cases are chemoresistant. Because the receptor tyrosine kinase AXL promotes invasion and metastasis of USC and is implicated in chemoresistance in other cancers, we assessed the role of AXL in paclitaxel resistance in USC, determined the mechanism of action, and sought to restore chemosensitivity by inhibiting AXL in vitro and in vivo We used short hairpin RNAs and BGB324 to knock down and inhibit AXL. We assessed sensitivity of USC cell lines to paclitaxel and measured paclitaxel intracellular accumulation in vitro in the presence or absence of AXL. We also examined the role of the epithelial-mesenchymal transition (EMT) in AXL-mediated paclitaxel resistance. Finally, we treated USC xenografts with paclitaxel, BGB324, or paclitaxel plus BGB324 and monitored tumor burden. AXL expression was higher in chemoresistant USC patient tumors and cell lines than in chemosensitive tumors and cell lines. Knockdown or inhibition of AXL increased sensitivity of USC cell lines to paclitaxel in vitro and increased cellular accumulation of paclitaxel. AXL promoted chemoresistance even in cells that underwent the EMT in vitro Finally, in vivo studies of combination treatment with BGB324 and paclitaxel showed a greater than 51% decrease in tumor volume after 2 weeks of treatment when compared with no treatment or single-agent treatments ( P USC.

    Full Text Available AIM: To investigate the association of serum glucocorticoid kinase gene-1 (SGK-1 DNA variants with chronic central serous chorioretinopathy (CSC. METHODS: We enrolled 32 eyes of 32 patients who were diagnosed with chronic CSC and composed 32 normal eyes as a control group. Peripheral blood was used for DNA extraction and polymerase chain reaction (PCR amplification. SGK1 gene was sequenced by using BigDye® Terminator v3.1 cycle sequencing KIT (Applied Biosystems, Foster City, CA, USA. The SGK1 gene and its variants were investigated in CSC patient group and control group. RESULTS: We identified a new polymorphism M32V in two person in the patient group (Minor allele frequency (MAF=0.009 on the region of 1-60 amino acids. The rs1057293 was located in the encoder region of the SGK 1 gene but not associated with CSC (P=0.68. An intrinsic rs1743966 is also not associated (P=0.28. CONCLUSIONS: The new polymorphism M32V is located on the region of 1-60 amino acids which is necessary for localization to the mitochondria in CSC patient. This mutation is probably important for the energy metabolism and plays an important role in the cellular response to hyperosmotic stress and other stress stimuli. Both rs1057293 and rs1743966 are not associated with CSC.

    The immune system plays a critical role in cancer progression and overall survival. Still, it is unclear if differences in the immune response are associated with different patterns of tumor spread apparent in high grade serous ovarian cancer patients and previously described by us. In this study we aimed to assess the role of the immune system in miliary (widespread, millet-sized lesions) and non-miliary (bigger, exophytically growing implants) tumor spread. To achieve this we comprehensively analyzed tumor tissues, blood, and ascites from 41 patients using immunofluorescence, flow cytometry, RNA sequencing, multiplexed immunoassays, and immunohistochemistry. Results showed that inflammation markers were systemically higher in miliary. In contrast, in non-miliary lymphocyte and monocyte/macrophage infiltration into the ascites was higher as well as the levels of PD-1 expression in tumor associated cytotoxic T-lymphocytes and PD-L1 expression in tumor cells. Furthermore, in ascites of miliary patients more epithelial tumor cells were present compared to non-miliary, possibly due to the active down-regulation of anti-tumor responses by B-cells and regulatory T-cells. Summarizing, adaptive immune responses prevailed in patients with non-miliary spread, whereas in patients with miliary spread a higher involvement of the innate immune system was apparent while adaptive responses were counteracted by immune suppressive cells and factors.

    To investigate a possible relationship between central serous chorioretinopathy (CSC) and specific body types and compositions (somatotypes), and to examine the cortisol stress response among CSC patients of different somatotypes in comparison with healthy subjects. Prospective case-control study. A group of 28 patients with a previous or current diagnosis of CSC was compared with a group of 26 healthy subjects. Anthropometric measurements were used to estimate somatotype ratings in all subjects. Serum cortisol was measured at rest and following a stress-inducing computerized test in order to estimate response to stress in both groups. The main outcome measures included somatotype categorization and the change in serum cortisol following stress in both groups. No significant difference in somatotype composition was found between the groups. There was no statistically significant difference between the groups in the elevation of cortisol following the stress-inducing test. The sample size was too small to exclude or find any significant difference between the different 13 subgroups of somatotype composition in the elevation of cortisol. Our study did not show a typical somatotype related to CSC. While previous studies showed higher cortisol values in CSC patients, we did not see a higher elevation in blood cortisol following a stress response in this group in comparison with healthy subjects.

  14. The Molecular Fingerprint of High Grade Serous Ovarian Cancer Reflects Its Fallopian Tube Origin

    2013-03-01

    Full Text Available High grade serous ovarian cancer (HGSC, the most lethal and frequent type of epithelial ovarian cancer (EOC, has poor long term prognosis due to a combination of factors: late detection, great metastatic potential and the capacity to develop resistance to available therapeutic drugs. Furthermore, there has been considerable controversy concerning the etiology of this malignancy. New studies, both clinical and molecular, strongly suggest that HGSC originates not from the surface of the ovary, but from the epithelial layer of the neighboring fallopian tube fimbriae. In this paper we summarize data supporting the central role of fallopian tube epithelium in the development of HGSC. Specifically, we address cellular pathways and regulatory mechanisms which are modulated in the process of transformation, but also genetic changes which accumulate during disease progression. Similarities between fallopian tube mucosa and the malignant tissue of HGSC warrant a closer analysis of homeostatic mechanisms in healthy epithelium in order to elucidate key steps in disease development. Finally, we highlight the importance of the cancer stem cell (CSC identification and understanding of its niche regulation for improvement of therapeutic strategies.

    Serous carcinoma of the uterine cervix (USCC) is an extremely rare subtype. To establish the treatment strategy in patients with USCC is an important issue. MEDLINE (PubMed) was searched for all articles published after the first publication by Lurie et al. [Eur J Obstet Gynecol Reprod Biol 1991; 40: 79-81], reporting woman diagnosed with USCC. Because of limited numbers of studies on the topic of the study, we could not keep a restriction of eliminating smaller sample sizes. A search of PubMed demonstrated that 113 cases of USCC have been reported in the literature since the first publication. The current treatment modality adopted for early cervical cancer is hysterectomy with bilateral iliac-obturator lymphadenectomy and postoperative radiotherapy (RT) or radiochemotherapy (RT-CT) if risk factors for cervical carcinoma appear. The treatment strategy for locally advanced USCC is preoperative RT-CT or chemotherapy (CHTH) with the intention to treat the patient surgically. The treatment option for disseminated disease is CHTH with paclitaxel and carboplatin. Risk factors and a more advanced clinical stage of USCC have an impact on poor outcomes despite the use of standard treatment methods, adapted for cervical cancer. The outside-pelvic failures tend to seek effective systemic treatment. © 2018 S. Karger AG, Basel.

    Central serous chorioretinopathy (CSC), a specific form of macular degeneration, has been reported as presenting manifestation of Cushing's syndrome. Furthermore, CSC has been associated with both exogenous hypercortisolism and endogenous Cushing's syndrome. It is important to know whether CSC patients should be screened for Cushing's syndrome. Although hypothalamic-pituitary-adrenal (HPA) axis hyperactivity in CSC has been suggested, no detailed evaluation of the HPA axis has been performed in a large cohort of CSC patients. This study aimed to investigate whether Cushing's syndrome prevalence is increased among chronic CSC (cCSC) patients and whether detailed endocrinological phenotyping indicates hyperactivity of the HPA axis. Cross-sectional study. 86 cCSC patients and 24 controls. Prevalence of Cushing's syndrome, HPA axis activity. None of the cCSC patients met the clinical or biochemical criteria of Cushing's syndrome. However, compared to controls, HPA axis activity was increased in cCSC patients, reflected by higher 24 h urinary free cortisol, and accompanying higher waist circumference and diastolic blood pressure, whereas circadian cortisol rhythm and feedback were not different. Chronic CSC patients did not report more stress or stress-related problems on questionnaires. No case of Cushing's syndrome was revealed in a large cohort of cCSC patients. Therefore, we advise against screening for Cushing's syndrome in CSC patients, unless additional clinical features are present. However, our results indicate that cCSC is associated with hyperactivity of the HPA axis, albeit not accompanied with perception of more psychosocial stress.

    To report the MRI appearance of serous atrophy of bone marrow (SABM) and analyse clinical findings and complications of SABM. A retrospective search of MRI examinations of SABM was performed. Symptoms, underlying conditions, MRI findings, delay in diagnosis and associated complications were recorded. We identified 30 patients (15 male, 15 female; mean age: 46 ± 21 years) with MRI findings of SABM. Underlying conditions included anorexia nervosa (n = 10), cachexia from malignant (n = 5) and non-malignant (n = 7) causes, massive weight loss after bariatric surgery (n = 1), biliary atresia (n = 1), AIDS (n = 3), endocrine disorders (n = 2) and scurvy (n = 1). MRI showed mildly hypointense signal on T1- weighted and hyperintense signal on fat-suppressed fluid-sensitive images of affected bone marrow in all cases and similar signal abnormalities of the adjacent subcutaneous fat in 29/30 cases. Seven patients underwent repeat MRI due to initial misinterpretation of bone marrow signal as technical error. Superimposed fractures of the hips and lower extremities were common (n = 14). SABM occurs most commonly in anorexia nervosa and cachexia. MRI findings of SABM are often misinterpreted as technical error requiring unnecessary repeat imaging. SABM is frequently associated with fractures of the lower extremities. (orig.)

    to investigate peculiarities of psycho-emotional reactions in patients with central serous chorioretinopathy (CSCR). The study involved 35 patients with CSCR (mean age of 47.7±8.5 years) and 26 volunteers without visual impairment (mean age of 35.8±4.5 years). Their psycho-emotional state was studied using the SCL-90-R questionnaire (the severity of psychopathological symptomatology), TOBOL method (the type of attitude to the disease), Ways of Coping Questionnaire (WCQ) (strategies for controlling behavior), Spielberger-Hanin method (the level of anxiety), and the VFQ-25 questionnaire (quality of life). The psycho-emotional state of CSCR patients is characterized by elevated levels of depressive and paranoiac symptoms, obsessions, compulsions, and anxiety. Such patients tend to show supernatural, sthenic desire to maintain their professional status. They tend to try to resolve the conflict by denying the problem, imagining things and distracting oneself. They also show reactive and personal anxiety. In this study, their quality of life was significantly lower than that in healthy volunteers, vision-related criteria particularly concerned. Patients with CSCR demonstrate certain psycho-emotional features that can aggravate their general medical condition as well as the ophthalmic status.

    This research investigated the peripheral retinas of patients with central serous chorioretinopathy (CSCR). Sixty patients with CSCR and 60 age- and gender-matched controls were included in this prospective cross-sectional study. All 120 participants underwent ocular examinations and peripheral retinal evaluations using a Goldmann three-mirror lens. The examinations demonstrated peripheral retinal degeneration, atrophic or hyperplastic retinal pigment epithelial changes, and retinal breaks. The peripheral retinal degeneration rate was 39% in the CSCR group and 15% in the control group, and the CSCR group reported significantly more lattice degeneration than the control group (22 vs. 3%) (P = 0.004, odds ratio = 1.97, confidence interval = 0.68-5.65 and P = 0.002, odds ratio = 4.55, confidence interval = 0.77-26.83, respectively). Symptomatic U-shaped retinal breaks were found in three eyes (5%) in the CSCR group, and the rate of peripheral retinal degeneration was higher in the patients with chronic CSCR (vs. acute CSCR). However, this difference was not significant (P = 0.244). This study showed that peripheral retinal abnormalities, particularly lattice degeneration, are more common in patients with CSCR. Therefore, the authors recommend regular retinal examinations, with the inclusion of peripheral retinal assessments, for patients with CSCR.

    We sought to identify stable single-gene prognostic signatures based on a large collection of advanced stage serous ovarian cancer (AS-OvCa) gene expression data and explore their functions. The empirical Bayes (EB) method was used to remove the batch effect and integrate 8 ovarian cancer datasets. Univariate Cox regression was used to evaluate the association between gene and overall survival (OS). The Database for Annotation, Visualization and Integrated Discovery (DAVID) tool was used for the functional annotation of genes for Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. The batch effect was removed by the EB method, and 1257 patient samples were used for further analysis. We selected 341 single-gene prognostic signatures with FDR matrix organization, focal adhesion and DNA replication which are closely associated with cancer. We used the EB method to remove the batch effect of 8 datasets, integrated these datasets and identified stable prognosis signatures for AS-OvCa.

    Full Text Available Psychological stress is a risk factor as well as a consequence of central serous chorioretinopathy (CSC. Impulsiveness, overachievement, emotional instability, and hard-driving competitiveness have been discussed as personality features in CSC patients. We investigated 57 consecutive CSC patients and 57 age- and gender-matched controls by means of the Symptom Checklist 90-R and the Temperament and Character Inventory. Somatic risk factors, illness characteristics, subjective assessment of severity of illness, and illness-related stress in different areas of life (work, private life were evaluated. CSC patients showed significantly higher emotional distress as measured by the Global Severity Index. The CSC personality was characterized by lower scoring on the character dimension cooperativeness and the temperament dimension reward dependence. Cooperativeness as well as subjective assessment of severity of CSC has been recognized as significant predictors of illness-related work stress accounting for 30% of variance. Implicating competitiveness, hostility and emotional detachment, lower level of cooperativeness, and reward dependence support the existence of specific aspects of type A behaviour in CSC patients. Low perceived social support and loss of control may explain the significant contribution of this personality dimension to illness-related work stress. Treatment of CSC should thus incorporate psychoeducation about factors contributing to illness-related stress.

    To describe imaging findings of arterial hypervascular solid-appearing serous cystic neoplasms (SCNs) of the pancreas on CT and MR and determine imaging features differentiating them from neuroendocrine tumours (NETs). We retrospectively identified 15 arterial hypervascular solid-appearing SCNs and randomly chose 30 size-matched pancreatic NETs. On CT, two radiologists in consensus assessed the size, morphology, and CT attenuation. On MR, predominant signal intensity and the amount of the cystic component on T2-weighted images and ADC maps were evaluated and compared using Fisher's exact and Student's t-test. The mean SCN size was 2.6 cm (range, 0.8-8.3). The CT findings were similar between the two tumours: location, shape, margin, and enhancement pattern. SCNs were significantly more hypodense on non-enhanced CT images than NETs (P =.03). They differed significantly on MR: bright signal intensity (P =.01) and more than a 10 % cystic component on T2-weighted images (P =.01) were more common in SCNs than in NETs. All SCNs showed a non-restrictive pattern on the ADC map, while NETs showed diffusion restriction (P <.01). Arterial hypervascular solid-appearing SCNs and NETs share similar imaging features. Non-enhanced CT and MR images with T2-weighted images and ADC maps can facilitate the differentiation. (orig.)

    To evaluate early choroidal vascular dye-filling and dye propagation patterns in normal subjects and in patients with central serous chorioretinopathy (CSC) using indocyanine green (ICG) angiography. Seventeen healthy volunteers (21-81 years old) and six patients with CSC were included. ICG angiography was performed using a modified Topcon ICG video-camera system. Subtracted images were made using the early ICG frames at a time interval of 0.12 s. Ninety frames of time-sequential images for 3 s starting from the initial dye appearance in the choroid were prepared to construct an animated video. The animated video demonstrated dye-filling and propagation patterns at the level of the choroid-choriocapillaris. In normal young volunteers, the initial phase of dye filling appeared as a uniform patchy fluorescence in the sub-foveal area, and then spread evenly in a centrifugal manner in all directions in a wave-like, pulsed fashion towards the equator. In normal older volunteers, the initial phase was similar to that in young volunteers, but centrifugal flow propagation of fluorescence towards the periphery showed an uneven progression and border. In patients with CSC, the initial dye showed a multiple patchy dye appearance with a significant time delay and loss of the centrifugal extension pattern. Using this new approach, various choroidal dye propagation patterns were observed in normal volunteers and in patients with CSC. A video of subtracted images allowed evaluation of the dynamics of dye propagation in the choroid-choriocapillaris.

    Full Text Available Introduction: An entirely new type of staphyloma has been recently described as dome-shaped macula (DSM. It is characterized by an abnormal convex macular contour within the concavity of a posterior staphyloma. We found DSM associated with serous macular detachment (SMD and tilted disc in two consecutive cases. Case Reports: Case 1: A 37-year-old female presented to our department because of sudden onset blurred vision in her right eye (OD. The best-corrected visual acuity (BCVA was 0.5 in both eyes. Funduscopy evidenced bilateral tilted disc associated with posterior staphyloma. Optical coherence tomography (OCT demonstrated a DSM with SMD in her OD. After 15 months of follow-up, BCVA of her OD remained stable with chronic SMD. Case 2: A 32-year-old female presented to our department because of blurred vision in her OD. The BCVA was 0.4 in the OD and 1.0 in the left eye (OS. Bilateral tilted disc and posterior staphyloma were evidenced in the funduscopy. OCT demonstrated a bilateral DSM with SMD in her OD. After 45 months of follow-up, two further episodes of transient SMD were observed in her OD and seven in her OS. The final BCVA was 0.63 in the OD and 0.8 in the OS. Discussion: SMD associated with tilted disc constitutes a potential cause of subretinal fluid accumulation in myopic patients. OCT is essential for the detection of both SMD and DSM.

    To study morphologically and functionally the prognosis of damaged outer segments of the foveal photoreceptor layer in eyes with resolved central serous chorioretinopathy (CSC). We studied retrospectively the medical records of 70 patients (74 eyes) with resolved CSC. Optical coherence tomography was used to detect the junctions between inner and outer segments of the photoreceptors (IS/OS) as a hallmark of the integrity of the outer photoreceptor layer. In 53 eyes (71.6%), the IS/OS line was clearly detected beneath the fovea immediately after resolution of the retinal detachment, with good visual acuity (VA). In the remaining 21 eyes (28.4%), however, the foveal IS/OS line could not be detected shortly after resolution of CSC, and VA was variable, ranging from 0.1 to 1.5 (median, 0.9). Of these 21 eyes, 15 had a follow-up examination with OCT, and in four the foveal IS/OS line was not detected at the follow-up and vision in these eyes remained poor. However, nine eyes showed recovery of the foveal IS/OS line during follow-up, and these eyes had substantial visual recovery. Immediately after resolution of active CSC, although the IS/OS line cannot be detected beneath the fovea, it often shows restoration over time, with visual recovery, though in some eyes no restoration takes place and the prognosis remains poor.

    Purpose To evaluate interradiologist agreement on assessments of computed tomography (CT) imaging features of high-grade serous ovarian cancer (HGSOC), to assess their associations with time-to-disease progression (TTP) and HGSOC transcriptomic profiles (Classification of Ovarian Cancer [CLOVAR]), and to develop an imaging-based risk score system to predict TTP and CLOVAR profiles. Materials and Methods This study was a multireader, multi-institutional, institutional review board-approved, HIPAA-compliant retrospective analysis of 92 patients with HGSOC (median age, 61 years) with abdominopelvic CT before primary cytoreductive surgery available through the Cancer Imaging Archive. Eight radiologists from the Cancer Genome Atlas Ovarian Cancer Imaging Research Group developed and independently recorded the following CT features: characteristics of primary ovarian mass(es), presence of definable mesenteric implants and infiltration, presence of other implants, presence and distribution of peritoneal spread, presence and size of pleural effusions and ascites, lymphadenopathy, and distant metastases. Interobserver agreement for CT features was assessed, as were univariate and multivariate associations with TTP and CLOVAR mesenchymal profile (worst prognosis). Results Interobserver agreement for some features was strong (eg, α = .78 for pleural effusion and ascites) but was lower for others (eg, α = .08 for intraparenchymal splenic metastases). Presence of peritoneal disease in the right upper quadrant (P = .0003), supradiaphragmatic lymphadenopathy (P = .0004), more peritoneal disease sites (P = .0006), and nonvisualization of a discrete ovarian mass (P = .0037) were associated with shorter TTP. More peritoneal disease sites (P = .0025) and presence of pouch of Douglas implants (P = .0045) were associated with CLOVAR mesenchymal profile. Combinations of imaging features contained predictive signal for TTP (concordance index = 0.658; P = .0006) and CLOVAR profile (mean

    The insulin-like growth factor I receptor (IGF-IR) and BRCA1 affect cell growth and apoptosis. Little information is available about BRCA1 activity on the IGF signaling pathway. This study evaluated the effect of BRCA1 on IGF-IR expression. BRCA1 and IGF-IR immunohistochemistry on archival tissues (35 uterine serous carcinomas [USCs] and 17 metastases) were performed. USPC1 and USPC2 cell lines were transiently cotransfected with an IGF-IR promoter construct driving a luciferase reporter gene and a BRCA1 expression plasmid. Endogenous IGF-IR levels were evaluated by Western immunoblotting. We found high BRCA1 and IGF-IR protein expression in primary and metastatic USC tumors. All samples were immunostained for BRCA1-71% strongly stained; and 33/35 (94%) were stained positive for IGF-IR-2 (6%) strongly stained. No difference in BRCA1 and IGF-IR staining intensity was noted between BRCA1/2 mutation carriers and noncarriers. Metastatic tumors stained more intensely for BRCA1 than did the primary tumor site (P = 0.041) and with borderline significance for IGF-IR (P = 0.069). BRCA1 and IGF-IR staining did not correlate to survival. BRCA1 expression led to 35% and 54% reduction in IGF-IR promoter activity in the USPC1 and USCP2 cell lines, respectively. Western immunoblotting showed a decline in phosphorylated IGF-IR and phosphorylated AKT in both transiently and stably transfected cells. BRCA1 and IGF-IR are highly expressed in USC tumors. BRCA1 suppresses IGF-IR gene expression and activity. These findings suggest a possible biological link between the BRCA1 and the IGF-I signaling pathways in USC. The clinical implications of this association need to be explored.

    Full text of the publication follows: Thyroid cancer is one of the malignancies most strongly associated with ionizing radiation in humans. Epidemiology studies of atomic bomb (A-bomb) survivors have indicated that excess relative risk of papillary thyroid cancer per Gy was remarkably high in the survivors. We therefore aim to clarify mechanisms linking A-bomb radiation exposure and development of papillary thyroid cancer. Toward this end, we intend to clarify characteristics of gene alterations occurring in radiation-associated adult-onset papillary thyroid cancer from the Life Span Study cohort of A-bomb survivors. We have thus far found that with increased radiation dose, papillary thyroid cancer cases with chromosomal rearrangements (mainly RET/PTC rearrangements) significantly increased and papillary thyroid cancer cases with point mutations (mainly BRAF-V600E) significantly decreased. Papillary thyroid cancer cases with non-detected gene alterations that carried no mutations in RET, NTRK1, BRAF or RAS genes tended to increase with increased radiation dose. In addition, we found that relative frequency of these papillary thyroid cancer cases significantly decreased with time elapsed since exposure. Through analysis of papillary thyroid cancer cases with non-detected gene alterations, we recently discovered a new type of rearrangement for the first time in papillary thyroid cancer, i.e., rearranged anaplastic lymphoma kinase (ALK) gene, although identification of any partner gene(s) is needed. Specifically, rearrangement of ALK was found in 10 of 19 exposed papillary thyroid cancer cases with non-detected gene alterations but not in any of the six non-exposed papillary thyroid cancer cases. Furthermore, papillary thyroid cancer with ALK rearrangement was frequently found in the cases with high radiation dose or with short time elapsed since A-bomb exposure. These results suggest that chromosomal rearrangement, typically of RET and ALK, may play an important

    For patients with branch duct intraductal papillary mucinous neoplasms (BD-IPMNs, cysts), it is a challenge to identify those at high risk for malignant lesions. We sought to identify factors associated with development of pancreatic cancer, focusing on neoplasm growth rate. We performed a retrospective study of 189 patients with BD-IPMNs who underwent at least 2 contrast-enhanced cross-sectional imaging studies, 1 year or more apart, at a tertiary referral center from January 2003 through 2013. Patients with cysts that had Fukuoka worrisome or high-risk features were excluded. Two radiologists reviewed all images. Cyst size was recorded at the initial and final imaging studies and growth rate was calculated. We collected patient demographic data, cyst characteristics, and clinical outcomes; univariate logistic regression models were used to determine the odds of developing worrisome features. The primary outcomes were to determine growth rate of low-risk BD-IPMNs and to assess whether cyst growth rate correlates high-risk features of IPMNs. Based on image analyses, cysts were initially a median 11 mm (range, 3-31 mm) and their final size was 12.5 mm (range, 3-42 mm). After a median follow-up time of 56 months (range, 12-163 months), the median cyst growth rate was 0.29 mm/year. Twelve patients developed worrisome features, no patients developed high-risk features, 4 patients had surgical resection, and no cancers developed. The rate of BD-IPMN growth was greater in patients who developed worrisome features than those who did not (2.84 mm/year vs 0.23 mm/year; P < .001). The odds of developing worrisome features increased for each unit (mm) increase in cyst size (odds ratio, 1.149; 95% CI, 1.035-1.276, P = .009). In a retrospective analysis of images from patients with BD-IPMN, we found low-risk BD-IPMNs to grow at an extremely low rate (less than 0.3 mm/year). BD-IPMNs in only about 6% of patients developed worrisome features, and none developed high-risk features

    Abstract This study aims to investigate the impact of psammoma body (PB) on papillary thyroid carcinoma (PTC), and evaluate the association among PB, Hashimoto thyroiditis (HT), and other clinicopathologic characteristics in PTC patients. We conducted a retrospective case-control study involving 1052 PTC patients who underwent total thyroidectomy or lobectomy with lymph node dissection. Psammoma body was observed in 324 out of 1052 PTC (30.8%) patients. Ultrasonographic (US) calcification (P < 0.001), multifocality of the tumor (P = 0.047), lymph node metastasis (LNM) (P < 0.001), HT (P < 0.001), and Primary tumor (T), Regional lymph nodes (N), Distant metastasis (M) staging (P = 0.001) were significantly related to the presence of PB. The presence of PB was significantly associated with US microcalcification (P < 0.001). In the subgroup with HT, compared with the patients without PB, the patients with PB exhibited a higher frequency of central LNM (54.7% vs 32.1%; P < 0.001) and US microcalcification (94.7% vs 38.8%; P < 0.001), as well as smaller tumors (0.9 ± 0.6 vs 1.3 ± 0.9 cm; P < 0.001). In the subgroup without HT, the patients with PB displayed a higher incidence of lateral LNM (25.8% vs 14.6%; P < 0.001), US microcalcification (87.3% vs 52.5%; P < 0.001), and extrathyroidal extension (47.2% vs 34.8%; P = 0.001), as well as larger tumors (1.3 ± 0.9 vs 1.0 ± 0.8 cm; P < 0.001) than without PB. Moreover, in the subgroup with PB, the PTC patients with HT showed a higher LNM (77.9% vs 57.2%; P < 0.001) and a lower frequency of extrathyroidal extension (20.0% vs 47.2%; P < 0.001) than without HT. Psammoma body is a useful predictor of aggressive tumor behavior in PTC patients. HT with PB shows more aggressive behaviors than non-HT with PB in PTC patients. PMID:26554782

    Concurrent thyroid cancer (TC) and hyperthyroidism (HT) is rare though increasingly being reported. HT due to TC is much rarer and more challenging especially in Africa where TC and HT have significant case fatality rates. We present a 37-year-old Cameroonian female who had been on irregular regimens of propranolol and digoxin as treatment for worsening palpitations for 12 months. She came to our district hospital for her propranolol medication refill. We fortuitously identified features of HT and found a left uninodular goiter with no cervical lymphadenopathy. She was referred for thyroid assessment which suggested primary HT and an enlarged heterogeneous left lobe with a well-defined homogenous solid mass. We restarted her on propranolol and referred her for a course of methimazole. At the referral hospital, she also underwent a left thyroid lobectomy. The resected lobe was sent for histopathology which revealed a neoplastic nodule with features suggestive of a papillary thyroid cancer (PTC) causing HT. The patient's clinical progress postoperatively was good and there was regression of hyperthyroid symptoms. The historical, clinical, and laboratory findings were suggestive of HT due to PTC. A high index of suspicion, prompt referral and counter-referral lead to a positive outcome of such a rare case in a resource poor setting. We advocate for systematic and careful evaluation of all thyroid nodules.

    2011-01-01

    Full Text Available Structural genomic rearrangements are frequent findings in human cancers. Therefore, papillary thyroid carcinomas (PTCs were investigated for chromosomal aberrations and rearrangements of the RET proto-oncogene. For this purpose, primary cultures from 23 PTC have been established and metaphase preparations were analysed by spectral karyotyping (SKY. In addition, interphase cell preparations of the same cases were investigated by fluorescence in situ hybridisation (FISH for the presence of RET/PTC rearrangements using RET-specific DNA probes. SKY analysis of PTC revealed structural aberrations of chromosome 11 and several numerical aberrations with frequent loss of chromosomes 20, 21, and 22. FISH analysis for RET/PTC rearrangements showed prevalence of this rearrangement in 72% (16 out of 22 of cases. However, only subpopulations of tumour cells exhibited this rearrangement indicating genetic heterogeneity. The comparison of visual and automated scoring of FISH signals revealed concordant results in 19 out of 22 cases (87% indicating reliable scoring results using the optimised scoring parameter for RET/PTC with the automated Metafer4 system. It can be concluded from this study that genomic rearrangements are frequent in PTC and therefore important events in thyroid carcinogenesis.

    Full Text Available Thyroid cancer affects over ½ million people in the U.S. and the incidence of thyroid cancer has increased worldwide at a rate higher than any other cancer, while survival has remained largely unchanged. The aim of this research was to develop, calibrate and verify a mathematical disease model to simulate the natural history of papillary thyroid cancer, which will serve as a platform to assess the effectiveness of clinical and cancer control interventions.Herein, we modeled the natural pre-clinical course of both benign and malignant thyroid nodules with biologically relevant health states from normal to detected nodule. Using established calibration techniques, optimal parameter sets for tumor growth characteristics, development rate, and detection rate were used to fit Surveillance Epidemiology and End Results (SEER incidence data and other calibration targets.Model outputs compared to calibration targets demonstrating sufficient calibration fit and model validation are presented including primary targets of SEER incidence data and size distribution at detection of malignancy. Additionally, we show the predicted underlying benign and malignant prevalence of nodules in the population, the probability of detection based on size of nodule, and estimates of growth over time in both benign and malignant nodules.This comprehensive model provides a dynamic platform employable for future comparative effectiveness research. Future model analyses will test and assess various clinical management strategies to improve patient outcomes related to thyroid cancer and optimize resource utilization for patients with thyroid nodules.

    The effect of coexistent chronic lymphocytic thyroiditis (CLT) on prognosis in papillary thyroid carcinoma (PTC) patients remains controversial. We evaluated the influence of coexistent CLT on prognostic outcome and the association of coexistent CLT with clinicopathological parameters. A retrospective study with a median follow-up of 70 months. Patients with PTC who underwent total thyroidectomy followed by (131)I remnant ablation between 1995 and 2003 at Asan Medical Center, Seoul, Korea were enrolled. CLT was diagnosed histopathologically. Among 1441 patients, 214 (14.9%) had coexistent CLT. A greater female preponderance was noted in the patients with CLT compared with those without CLT (P CLT was smaller than that in patients without CLT (2.0 +/- 1.2 vs. 2.2 +/- 1.4 cm; P = 0.02). One hundred and fifty-one (12.3%) patients without CLT had recurrence, whereas 14 (7.1%) patients with CLT had recurrence during the follow-up period (P = 0.016). In patients with cervical lymph node metastases, those with coexistent CLT showed a significantly lower recurrence rate than those without CLT (P = 0.012). However, this association was lost on multivariate analysis adjusting for other clinicopathological predictors for recurrence. In this study, CLT was commonly associated with PTC and was associated with smaller size of the primary tumour at presentation. CLT was also associated with a reduced risk of recurrence during follow-up, although this was not significant after adjustment for other prognostic factors.

    Uterine serous carcinoma (USC) is an aggressive type 2 endometrial cancer. Data on prognostic factors for patients with early-stage USC without adjuvant therapy are limited. This study aims to assess the baseline recurrence risk of early-stage USC patients without adjuvant treatment and to identify prognostic factors and patients who need adjuvant therapy. Sixty-eight patients with International Federation of Gynecology and Obstetrics (FIGO) stage I-II USC between 1997 and 2016 were included. All the cases did not undergo adjuvant treatment as institutional practice. Clinicopathological features, recurrence patterns, and survival outcomes were analyzed to determine prognostic factors. FIGO stages IA, IB, and II were observed in 42, 7, and 19 cases, respectively. Median follow-up time was 60 months. Five-year disease-free survival (DFS) and overall survival (OS) rates for all cases were 73.9% and 78.0%, respectively. On multivariate analysis, cervical stromal involvement and positive pelvic cytology were significant predictors of DFS and OS, and ≥1/2 myometrial invasion was also a significant predictor of OS. Of 68 patients, 38 patients had no cervical stromal invasion or positive pelvic cytology and showed 88.8% 5-year DFS and 93.6% 5-year OS. Cervical stromal invasion and positive pelvic cytology are prognostic factors for stage I-II USC. Patients with stage IA or IB USC showing negative pelvic cytology may have an extremely favorable prognosis and need not receive any adjuvant therapies. Copyright © 2018.

    To compare the lesion characteristics of two different types of confocal scanning laser ophthalmoscopy (cSLO) autofluorescence (AF) images in central serous chorioretinopathy (CSC). The study included 63 eyes of 61 patients; 63 pairs of fundus autofluorescence (FAF) images were compared before CSC resolution in 63 eyes, FAF images of 31 eyes were also compared after CSC resolution. The lesion characteristics (brightness and composite pattern) were compared between Heidelberg Retina Angiograph 2 (HRA2; Heidelberg Engineering, Germany) and Optomap Tx (Optomap; Optos, Scotland) FAF images. The lesion composite pattern was categorized as diffuse or granular. Diffuse AF was defined as homogenously increased or decreased AF, and granular AF was defined as dot-like, coarse changes in AF. The mean disease duration and subretinal fluid (SRF) height in the spectral domain optical coherence tomography were compared according to the FAF image characteristics. Lesion brightness before CSC resolution was hypo-AF in 48 eyes (76.2 %), hyper-AF in three (4.8 %), and mixed-AF in 12 (19.0 %) in HRA2 FAF images. In comparison, nine (14.3 %) images were hypo-AF, 44 (69.8 %) were hyper-AF, and 10 (15.9 %) were mixed-AF in Optomap FAF images (P < 0.0001). There was no significant difference in lesion composite pattern between the two FAF image wavelengths. Patients with lesions that were hyper-AF in Optomap FAF and hypo-AF in HRA2 FAF had a shorter disease duration and greater SRF height (1 month, 281 um) than those who were hyper-AF in both Optomap and HRA2 images (26 months, 153 um; P = 0.004, 0.001). The two types of FAF images of CSC showed different lesion brightness before and after CSC resolution but demonstrated similar lesion composite patterns.

    Full Text Available ObjectiveCentral serous chorioretinopathy (CSC, a specific form of macular degeneration, has been reported as presenting manifestation of Cushing’s syndrome. Furthermore, CSC has been associated with both exogenous hypercortisolism and endogenous Cushing’s syndrome. It is important to know whether CSC patients should be screened for Cushing’s syndrome. Although hypothalamic-pituitary-adrenal (HPA axis hyperactivity in CSC has been suggested, no detailed evaluation of the HPA axis has been performed in a large cohort of CSC patients. This study aimed to investigate whether Cushing’s syndrome prevalence is increased among chronic CSC (cCSC patients and whether detailed endocrinological phenotyping indicates hyperactivity of the HPA axis.DesignCross-sectional study.Patients86 cCSC patients and 24 controls.MeasurementsPrevalence of Cushing’s syndrome, HPA axis activity.ResultsNone of the cCSC patients met the clinical or biochemical criteria of Cushing’s syndrome. However, compared to controls, HPA axis activity was increased in cCSC patients, reflected by higher 24 h urinary free cortisol, and accompanying higher waist circumference and diastolic blood pressure, whereas circadian cortisol rhythm and feedback were not different. Chronic CSC patients did not report more stress or stress-related problems on questionnaires.ConclusionNo case of Cushing’s syndrome was revealed in a large cohort of cCSC patients. Therefore, we advise against screening for Cushing’s syndrome in CSC patients, unless additional clinical features are present. However, our results indicate that cCSC is associated with hyperactivity of the HPA axis, albeit not accompanied with perception of more psychosocial stress.

    Full Text Available Abstract Background There is a critical need for improved diagnostic markers for high grade serous epithelial ovarian cancer (SEOC. MicroRNAs are stable in the circulation and may have utility as biomarkers of malignancy. We investigated whether levels of serum microRNA could discriminate women with high-grade SEOC from age matched healthy volunteers. Methods To identify microRNA of interest, microRNA expression profiling was performed on 4 SEOC cell lines and normal human ovarian surface epithelial cells. Total RNA was extracted from 500 μL aliquots of serum collected from patients with SEOC (n = 28 and age-matched healthy donors (n = 28. Serum microRNA levels were assessed by quantitative RT-PCR following preamplification. Results microRNA (miR-182, miR-200a, miR-200b and miR-200c were highly overexpressed in the SEOC cell lines relative to normal human ovarian surface epithelial cells and were assessed in RNA extracted from serum as candidate biomarkers. miR-103, miR-92a and miR -638 had relatively invariant expression across all ovarian cell lines, and with small-nucleolar C/D box 48 (RNU48 were assessed in RNA extracted from serum as candidate endogenous normalizers. No correlation between serum levels and age were observed (age range 30-79 years for any of these microRNA or RNU48. Individually, miR-200a, miR-200b and miR-200c normalized to serum volume and miR-103 were significantly higher in serum of the SEOC cohort (P  Conclusions We identified serum microRNAs able to discriminate patients with high grade SEOC from age-matched healthy controls. The addition of these microRNAs to current testing regimes may improve diagnosis for women with SEOC.

    Full Text Available Purpose. To evaluate the retinal vessel oxygen saturation in central serous chorioretinopathy (CSC cases among the Chinese. Methods. Relative oxygen saturation of retinal blood vessels was measured in 33 Chinese patients with single-eye CSC using the Oxymap T1 retinal oximeter. The contralateral eyes were the control. The mean saturation of the retinal arteriole (AS and venule (VS, arteriovenous difference (AVS, and arteriole and venule diameters (AD, VD was analyzed in the optic disc area and macular region. Results. In the optic disc area, the inferotemporal quadrant (TI AS (93.2 ± 10.2% and inferonasal quadrant (NI VS (61.3 ± 7.3% were higher in the affected eyes than in the contralateral eyes (88.7 ± 7.7% and 56.9 ± 6.5% and AVS in NI (36.7 ± 10.4% decreased compared to the contralateral eyes (41.5 ± 11.2%. The VD in TI was expanded (19.9 ± 2.5 pixels versus 18.1 ± 3.4 pixels. Around the macular region, AS was 93.6 ± 7.6%, higher than in the contralateral eyes (89.5 ± 6.3%. No other significant changes were found. Conclusions. AS increased in the TI, and VS decreased in the NI in the eyes with CSC. In addition, AS also increased around the macular region, suggesting that these are contributors to CSC pathophysiology.

    Smoking is a risk factor for mucinous ovarian cancer (OvCa) in Caucasians. Whether a similar association exists in African Americans (AA) is unknown. We conducted a population-based case-control study of incident OvCa in AA women across 11 geographic locations in the US. A structured telephone interview asked about smoking, demographic, health, and lifestyle factors. Odds ratios and 95% confidence intervals (OR, 95% CI) were estimated from 613 cases and 752 controls using unconditional logistic regression in multivariable adjusted models. Associations were greater in magnitude for serous OvCa than for all OvCa combined. Compared to never smokers, increased risk for serous OvCa was observed for lifetime ever smokers (1.46, 1.11-1.92), former smokers who quit within 0-2 years of diagnosis (5.48, 3.04-9.86), and for total pack-years smoked among lifetime ever smokers (0-5 pack-years: 1.79, 1.23-2.59; >5-20 pack-years: 1.52, 1.05-2.18; >20 pack-years: 0.98, 0.61-1.56); however, we observed no dose-response relationship with increasing duration or consumption and no significant associations among current smokers. Smoking was not significantly associated with mucinous OvCa. Associations for all OvCa combined were consistently elevated among former smokers. The proportion of ever smokers who quit within 0-2 years was greater among cases (23%) than controls (7%). Cigarette smoking may be associated with serous OvCa among AA, which differs from associations reported among Caucasians. Exposure misclassification or reverse causality may partially explain the absence of increased risk among current smokers and lack of dose-response associations. Better characterization of smoking patterns is needed in this understudied population.

    Pelvic carcinosarcomas (PCSs) are rare aggressive biphasic tumors that localize in the ovary, fallopian tube, or peritoneum and present frequently as bilateral disease. We undertook a morphological, p53 immunohistochemical and TP53 gene mutational analysis study in a single institution cohort of 16 PCSs in order to investigate the nature of bilateral tumors and to shed light on their origin and pathogenesis. Of the 16 patients, 10 presented with bilateral disease, 6 with a carcinosarcoma in both adnexa, and the remaining cases with a carcinosarcoma in one adnexum and a carcinoma in the opposite. The carcinoma component showed high-grade serous features in 13/16 of cases (81 %). In 10 patients (63 %), a serous tubal intraepithelial carcinoma (STIC) was found, in one case bilateral, making a total of 11 STICs. STIC was found only in cases with a carcinoma component with high-grade serous features. All 10 bilateral tumors and all 11 PCS-associated STICs showed a similar p53 immunostaining pattern. At mutation analysis of the TP53 gene, all five bilateral PCS contained an identical mutation in both localizations. Furthermore, a TP53 mutation was found in 8 of 10 STICs, with an identical mutation in the associated PCS. The finding of similar p53 immunostaining in all bilateral cases and identical TP53 mutations in most PCS-associated STIC provides evidence for a clonal relation between these neoplastic lesions, supporting a metastatic nature of bilateral PCS and suggesting that they have an extraovarian origin in a STIC.

    Ovarian cancer is a heterogeneous disease and prognosis for apparently similar cases of ovarian cancer varies. Recurrence of the disease in early stage (FIGO-stages I-II) serous ovarian cancer results in survival that is comparable to those with recurrent advanced-stage disease. The aim of this study was to investigate if there are specific genomic aberrations that may explain recurrence and clinical outcome. Fifty-one women with early stage serous ovarian cancer were included in the study. DNA was extracted from formalin fixed samples containing tumor cells from ovarian tumors. Tumor samples from thirty-seven patients were analysed for allele-specific copy numbers using OncoScan single nucleotide polymorphism arrays from Affymetrix and the bioinformatic tool Tumor Aberration Prediction Suite. Genomic gains, losses, and loss-of-heterozygosity that associated with recurrent disease were identified. The most significant differences (p < 0.01) in Loss-of-heterozygosity (LOH) were identified in two relatively small regions of chromosome 19; 8.0-8,8 Mbp (19 genes) and 51.5-53.0 Mbp (37 genes). Thus, 56 genes on chromosome 19 were potential candidate genes associated with clinical outcome. LOH at 19q (51-56 Mbp) was associated with shorter disease-free survival and was an independent prognostic factor for survival in a multivariate Cox regression analysis. In particular LOH on chromosome 19q (51-56 Mbp) was significantly (p < 0.01) associated with loss of TP53 function. The results of our study indicate that presence of two aberrations in TP53 on 17p and LOH on 19q in early stage serous ovarian cancer is associated with recurrent disease. Further studies related to the findings of chromosomes 17 and 19 are needed to elucidate the molecular mechanism behind the recurring genomic aberrations and the poor clinical outcome

    Recent evidence suggests that ovarian high-grade serous carcinoma (HGSC) originates from the epithelium of the fallopian tube. However, most mouse models are based on the previous prevailing view that ovarian cancer develops from the transformation of the ovarian surface epithelium. Here, we report the extensive histological and molecular characterization of the mogp-TAg transgenic mouse, which expresses the SV40 large T-antigen (TAg) under the control of the mouse müllerian-specific Ovgp-1 promoter. Histological analysis of the fallopian tubes of mogp-TAg mice identified a variety of neoplastic lesions analogous to those described as precursors to ovarian HGSC. We identified areas of normal-appearing p53-positive epithelium that are similar to 'p53 signatures' in the human fallopian tube. More advanced proliferative lesions with nuclear atypia and epithelial stratification were also identified that were morphologically and immunohistochemically reminiscent of human serous tubal intraepithelial carcinoma (STIC), a potential precursor of ovarian HGSC. Beside these non-invasive precursor lesions, we also identified invasive adenocarcinoma in the ovaries of 56% of the mice. Microarray analysis revealed several genes differentially expressed between the fallopian tube of mogp-TAg and wild-type (WT) C57BL/6. One of these genes, Top2a, which encodes topoisomerase IIα, was shown by immunohistochemistry to be concurrently expressed with elevated p53 and was specifically elevated in mouse STICs but not in the surrounding tissues. TOP2A protein was also found elevated in human STICs, low-grade and high-grade serous carcinoma. The mouse model reported here displays a progression from normal tubal epithelium to invasive HGSC in the ovary, and therefore closely simulates the current emerging model of human ovarian HGSC pathogenesis. This mouse therefore has the potential to be a very useful new model for elucidating the mechanisms of serous ovarian tumourigenesis, as well as

    Ectopic ovarian tissue is an unusual entity, especially if it is an isolated finding thought to be of embryological origin. An 11-year-old, morbidly obese female presented with left flank pain, nausea, and irregular menses. Various diagnostic procedures suggested a large ovarian cyst, and surgical resection was performed. Histologically, the resected mass was not of tubal origin as suspected, but a serous cystadenoma arising from ovarian tissue. The patient's two normal, eutopic ovaries were completely uninvolved and unaffected. A tumor arising from ectopic ovarian tissue of embryological origin seems the most likely explanation. We suggest refining the descriptive nomenclature so as to more precisely characterize the various presentations of ovarian ectopia.

    Full Text Available Classical papillary thyroid microcarcinoma (PTMC is a variant of papillary thyroid carcinoma (PTC known to have excellent prognosis. It has a mortality of 0.3%, even in the presence of distance metastasis. The latest American Thyroid Association guidelines state that although lobectomy is acceptable, active surveillance can be considered in the appropriate setting. We present the case of a 37-year-old female with a history of PTMC who underwent surgical management consisting of a total thyroidectomy. Although she has remained disease-free, her quality of life has been greatly affected by the sequelae of this procedure. This case serves as an excellent example of how first-line surgical treatment may result more harmful than the disease itself.

    Thyroid nodules are frequently found in association with Graves' disease. Papillary carcinoma can arise from these nodules. We report a 65-year-old gentleman who presented with classical features of Graves disease. Technetium 99 scintigraphy revealed diffuse goiter with a cold nodule over the isthmus. Papillary thyroid cancer was suggested by the enlarging thyroid gland, and by the presence of cold nodule, and was proven by fine needle aspiration biopsy of this nodule. The diagnosis was confirmed by histopathology of thyroid specimen after total thyroidectomy, which also showed local invasion; metastatic work up revealed pulmonary and liver metastasis. Despite treatment by total thyroidectomy, twice radioactive iodine I131 ablation and levothyroxine replacement in a thyroid stimulating hormone suppressive dose, he still harbors metastases with elevated thyroglobulin level. This case should raise the index of suspicion of the treating physician to consider similar association, and to prompt early diagnosis and surgical treatment to prevent dreadful consequences that might adversely affect the outcome.

    For the distribution of Tl 201 an analogous potassium membrane transport is assumed with the use of myocardial scintiscanning. This hypothesis was tested on the membrane model of the papillary muscle. The absorption and discharge behaviour of Tl 201 and K 42 was studied in isolated, stimulated papillary muscles from the right ventricle of a guinea pig heart in Ringer's solution at 36 0 C to answer the question of whether there are differences in ion transport. The results indicate only a partially similar membrane behaviour of K and Tl. Differences and similarities in the membrane transport of K and Tl allow themselves to be easily interpreted, when energetic, electric, and geometric factors as well as the various affinities of K and Tl for intracellular proteins are considered.

    The occurrence and diagnosis of thyroglossal duct carcinoma is very rare. The synchronous occurrence of papillary carcinomas arising in a thyroglossal duct cyst (TGDC) and thyroid gland is extremely rare. Sistrunk's surgical technique must always be the initial treatment for a TGDC. However, if there is an intra-thyroidal carcinoma or local invasion, thyroidectomy has to be considered. Accurate pre-operative radiological evaluation should be performed in order to plan a surgical strategy. The aim of this report was to review our experience in the management of papillary thyroid carcinoma associated with TGDC. Our patient was a 67-year-old man who had a mural, micro- calcified nodule within a palpable, thick-walled cyst at the level of the hyoid and synchronously, a small macro-calcified mass in the isthmus of the thyroid gland.

    Full Text Available Abstract Originally described in 1953, today the so-called J-wave is the source of much controversy. As a marker of so-called "early repolarization", this variant has been regarded as a totally benign variant since the 1960's. However, since then a wealth of data have indicated that the J-wave may be a marker of a highly arrhythmogenic substrate with a resultant high risk of sudden cardiac death. In this case report a case of an accessory papillary muscle with a prominent J-wave is described. This may be the first of many possible cases where papillary muscle variants may be the cause of the J-wave.

    Full Text Available We present a rare case of severe ischaemic papillary muscle rupture in a 67-year-old male patient who was admitted to the Emergency Department of the University Hospital Bern, Switzerland, in November 2013 with acute chest pain. On admission, the patient’s blood pressure was 60/40 mm/Hg, his pulse was 110 beats per minute and his respiratory rate was 20 breaths per minute. An electrocardiogram was normal and focused assessment with sonography in trauma was negative. Transthoracic echocardiography showed possible thickening of the mitral valve leaflet with no indications of severe mitral insufficiency or wall motion abnormalities. Triple-ruleout computed tomography angiography revealed no pulmonary emboli or aortic dissection, although coronary atherosclerosis was present. Finally, severe insufficiency of the mitral valve with rupture of the papillary muscle, likely due to ischaemia, was observed via transoesophageal echocardiography. The patient underwent a successful surgical intervention and was discharged 10 days later in stable condition.

    2010-04-01

    Full Text Available Ectopic cervical thymomas are often confused with thyroid or parathyroid swellings due to their anatomical positioning. Predominant epithelial thymoma can be misdiagnosed as papillary thyroid carcinoma on fine needle aspiration and lymph node metastasis of epithelial tumor on frozen section. Predominantly lymphocytic thymomas have often been misinterpreted as Hashimoto′s thyroiditis or malignant lymphoma, either by fine needle aspiration or on frozen section analysis. If cytology is doubtful and is not correlating with clinical, anatomical and surgical findings; immunohistochemistry is a very important tool in such cases to give final answer. Thyroid cell specific proteins such as thyroglobulin, thyroid transcription factor-1, thyroperoxidase and dipeptidyl aminopeptidase-4, neuroendocrine markers chromogranin, calcitonin and parathyroid hormone could be used to rule out thyroid or parathyroid origin. We present such rare case of ectopic cervical thymoma mimicking as papillary thyroid carcinoma.

    We report the MRI findings of three cases of intravascular papillary endothelial hyperplasia (IPEH) of the extremities with correlation of the pathologic findings. The IPEH is a non-neoplastic reactive lesion within the vessels and is commonly associated with thrombi. Signal intensity of the IPEH is complex due to the thrombi and the PEH itself. The thrombi are characterized by a slightly hyperintense signal on T1- and T2-weighted images compared with that of muscle when it comes at the medium stage of hemorrhage. Papillary endothelial hyperplastic tissue appears either as iso- or hyperintense to the muscle on T2- and T1-weighted images and shows variable enhancement on Gd-DTPA-enhanced images. (orig.)

    In this study, we aimed to evaluate the usefulness of a new parameter -ratio of the biggest tumor diameter to total tumor diameter- for the differentiation of agressive and favorable papillary thyroid microcarcinomas (PTMC). The diameter of the biggest tumor focus was taken as the primary tumor diameter. Total tumor diameter was calculated as the sum of the maximal diameter of each lesion. Ratio of primary tumor diameter to total tumor diameter was defined as tumor diameter ratio (TDR). Positive and negative predictive value, sensitivity and specificity of TDR to predict capsular invasion, extrathyroidal extension (ETE) and lymph node metastasis (LNM) were determined. Mean TDR was significantly lower in multifocal PTMC patients with capsular invasion, ETE, lymphovascular invasion and LNM compared to patients without these features. The sensitivities of TDR for the detection of LNM, ETE and capsular invasion were 100%, 100% and 94.2%, respectively. Specificity of TDR was 86.2% for LNM, 88% for ETE and 94.7% for capsular invasion. Best cut off values of TDR that can predict capsular invasion, ETE and LNM in multifocal PTMC were 0.62, 0.57 and 0.56, respectively. Multifocal papillary thyroid carcinoma patients with capsular invasion, ETE and LNM had significantly lower mean TDR when compared to ones without these features. Decreased TDR was associated with capsular invasion, ETE and LNM in patients with multifocal PTMC and PTC. This new parameter might be particularly helpful for the detection of aggressive behavior in multifocal PTMCs. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Papillary thyroid cancer is often described as the "good cancer" because of its treatability and relatively favorable survival rates. This study sought to characterize the thoughts of papillary thyroid cancer patients as they relate to having the "good cancer." This qualitative study included 31 papillary thyroid cancer patients enrolled in an ongoing randomized trial. Semi-structured interviews were conducted with participants at the preoperative visit and two weeks, six weeks, six months, and one year after thyroidectomy. Grounded theory was used, inductively coding the first 113 interview transcripts with NVivo 11. The concept of thyroid cancer as "good cancer" emerged unprompted from 94% (n = 29) of participants, mostly concentrated around the time of diagnosis. Patients encountered this perception from healthcare providers, Internet research, friends, and preconceived ideas about other cancers. While patients generally appreciated optimism, this perspective also generated negative feelings. It eased the diagnosis of cancer but created confusion when individual experiences varied from expectations. Despite initially feeling reassured, participants described feeling the "good cancer" characterization invalidated their fears of having cancer. Thyroid cancer patients expressed that they did not want to hear that it's "only thyroid cancer" and that it's "no big deal," because "cancer is cancer," and it is significant. Patients with papillary thyroid cancer commonly confront the perception that their malignancy is "good," but the favorable prognosis and treatability of the disease do not comprehensively represent their cancer fight. The "good cancer" perception is at the root of many mixed and confusing emotions. Clinicians emphasize optimistic outcomes, hoping to comfort, but they might inadvertently invalidate the impact thyroid cancer has on patients' lives.

    Adenomatous Tumors of the temporal bone are rare. Benign adenomatous neoplasms (adenoma) of the middle ear are a distinctive benign tumor based on histological and clinical observations. Papillary adenocarcinomas of the temporal bone are invasive tumors. Although, the exact site of origin of these neoplasms is not identified, owing to the local bone destruction (usually centered at posterior petromastoid plate), the general consensus favors the endolymphatic sac as being the origin of these t...

    Full Text Available Metastatic involvement of central lymph nodes in patients with papillary thyroid cancer (PTC is very common. However, prophylactic central lymph nodes dissection additionally to thyroidectomy does not significantly affect disease-free and overall survival of PTC patients. Meanwhile its routine conduction is tangibly increase postsurgical complications. From efficacy/safety point of view prophylactic central lymph nodes dissection couldn't be recommended as substantiated in all PTC patients.

    Standard therapy has not been established for thyroid cancer when a thyroidectomy is contraindicated due to systemic disease. Herein, we reported a patient who had hypertrophic cardiomyopathy and papillary thyroid carcinoma treated by radiofrequency ablation because of inability to tolerate a thyroidectomy. Radiofrequency ablation can be used to treat thyroid cancer when surgery is not feasible, although the long-term outcome needs further observation.

    There are 3 distinct variants of penile squamous cell carcinoma frequently associated with human papillomavirus (HPV): basaloid, warty-basaloid, and warty carcinomas. Considering the high incidence rates of penile cancer in some countries, a large international study was designed to evaluate the presence of HPV, its genotype distribution, and its association with histologic types of penile cancer. In this international review of >900 cases, we found a group of highly distinct papillary neoplasms composed of basophilic cells resembling urothelial tumors but frequently associated with HPV. Macroscopically, tumors were exophytic or exoendophytic. Microscopically, there was a papillomatous pattern of growth with a central fibrovascular core and small basophilic cells lining the papillae. Positivity for HPV was present in 11 of 12 tumors (92%). Single genotypes found were HPV-16 in 9 tumors and HPV-51 in 1 tumor. Multiple genotypes (HPV-16 and HPV-45) were present in another case. Overexpression of p16 was observed in all cases. Uroplakin-III was negative in all cases. The differential diagnosis was with basaloid, warty-basaloid, warty, and papillary squamous cell carcinoma and with urothelial carcinomas. Local excision (4 cases), circumcision (3 cases), or partial penectomy (5 cases) were preferred treatment choices. Tumor thickness ranged from 1 to 15 mm (average, 7 mm). Two patients with tumors invading 11 and 15 mm into the corpus spongiosum developed inguinal nodal metastasis. Of 11 patients followed up (median 48 mo), 7 were alive with no evidence of metastatic disease, 3 died from causes other than penile cancer, and another died postoperatively. This morphologically distinct tumor probably represents a papillary variant of basaloid carcinomas (papillary-basaloid carcinomas). Unlike typical basaloid carcinomas, the overall prognosis was excellent. However, deeply invasive tumors were associated with regional nodal metastasis indicating a potential for tumor

    Platinum-based combination therapy is the standard first-line treatment for women with advanced serous epithelial ovarian carcinoma (EOC). However, about 20 % will not respond and are considered clinically resistant. The availability of biomarkers to predict responses to the initial therapy would provide a practical approach to identify women who would benefit from a more appropriate first-line treatment. Ascites is an attractive inflammatory fluid for biomarker discovery as it is easy and minimally invasive to obtain. The aim of this study was to evaluate whether six selected inflammation-regulating factors in ascites could serve as diagnostic or drug resistance biomarkers in patients with advanced serous EOC. A total of 53 women with stage III/IV serous EOC and 10 women with benign conditions were enrolled in this study. Eleven of the 53 women with serous EOC were considered clinically resistant to treatment with progression-free survival < 6 months. Ascites were collected at the time of the debulking surgery and the levels of cytokines were measured by ELISA. The six selected cytokines were evaluated for their ability to discriminate serous EOC from benign controls, and to discriminate platinum resistant from platinum sensitive patients. Median ascites levels of IL-6, IL-10 and osteoprotegerin (OPG) were significantly higher in women with advanced serous EOC than in controls (P ≤ 0.012). There were no significant difference in the median ascites levels of leptin, soluble urokinase plasminogen activator receptor (suPAR) and CCL18 among serous EOC women and controls. In Receiver Operator curve (ROC) analysis, IL-6, IL-10 and OPG had a high area under the curve value of 0.905, 0.832 and 0.825 respectively for distinguishing EOC from benign controls. ROC analysis of individual cytokines revealed low discriminating potential to stratify patients according to their sensitivity to first-line treatment. The combination of biomarkers with the highest discriminating

    Full Text Available Aim To evaluate the usefulness of echocardiography in the diagnosis of complete rupture of papillary muscle. Methods Transthoracic (TTE and transesophageal echocardiography (TEE was performed with the ATL 3000 HDI Ultrasound Inc (Bothell, WA, USA with a 2.5 MHz transducer and 5-7 MHz multiplane phased array transducer. We are reporting about two patients (a 45 and a 51-year old male with complete ruptures of papillary muscle following acute myocardial infarction (AMI. Results Both patients were previously treated with fibrinolysis in their local hospitals, 400 and 300 km, respectively, away from our hospital. Massive mitral regurgitation developed in both followed by rapid deterioration of hemodynamic state and severe heart failure, because of which both were transferred by helicopter to the Coronary Care Unit of our clinic. The diagnosis of complete papillary muscle rupture was confirmed in both patients by TTE and TEE. Due to the significant deterioration in their hemodynamic state, vasoactive drugs and intra-aortic balloon pump support were applied. Both patients then underwent mitral valve replacement, accompanied by concomitant coronary artery bypass grafting in one case. Conclusion Transesophageal echocardiography is a more accurate and rapid diagnostic method in patients with mechanical complications of AMI than TTE.

    Mutations in FGFR3 and the promoter region of the telomerase reverse transcriptase (TERT) gene have been found frequently in urothelial carcinoma of the urinary bladder. However, related data for papillary urothelial neoplasm of low malignant potential (PUNLMP) are limited. In this study, we investigated the mutation status of the TERT promoter, FGFR3 and HRAS in low-grade papillary urothelial neoplasms and evaluated their prognostic significance. The cases included in this study comprised 21 inverted papillomas, 30 PUNLMPs and 34 low-grade non-invasive papillary urothelial carcinomas (NIPUCs). TERT promoter mutations were observed in 10 (33%) PUNLMPs and 17 (50%) low-grade NIPUCs, but not in any inverted papilloma. FGFR3 mutations were observed more frequently in PUNLMP and low-grade NIPUC than in inverted papillomas (P = 0.009), whereas the opposite trend was noted for HRAS mutations (P low-grade NIPUC (P = 0.530). Notably, PUNLMP cases with TERT promoter mutations had a similar recurrence rate to that in low-grade NIPUC cases (P = 0.487). Our results suggest that the status of the TERT promoter mutation may serve as a biomarker of prognostic stratification in patients with PUNLMP. © 2017 John Wiley & Sons Ltd.

    Full Text Available Objective: To investigate the changes of left ventricular papillary muscle action potentials in guinea pigs with iron deficiency anemia and heart failure. Methods: A total of 20 cases of iron deficiency anemia with heart failure were treated with experimental group and 10 normal guinea pigs as control group. Blood samples were collected to determine hemoglobin content, red blood cell number and whole blood iron index, and the changes of cardiac function and hemodynamics were detected by 6 240 biological signal collection system to determine whether the model was successful or not, Intracellular microelectrode technique was used to determine the action potentials of the papillary muscles in the model group and the control group. the potential amplitudes (APA, overshoot values (APA, maximum depolarization rate (Vmax, 20 % of repolarization, 50 % and 90 % of repolarization (APD20, APD50 and APD90 and the average velocity of repolarization were measured. Compare statistical difference between the model group and the control group. Results: 14 cases of model group survived completely, compared with control group, APD50 and APD90 prolonged, and the average velocity decreased. Conclusions: the action potential repolarization duration in the guinea pig papillary muscle of iron deficiency anemia with heart failure is prolonged, and the average repolarization velocity is slow.

    Full Text Available Background: Endoscopic-assisted transoral surgery, including transoral robotic surgery for metastatic retropharyngeal lymph node (RPN from well-differentiated thyroid cancer, has been reported to reduce the complications resulting from transcervical and transmandibular approaches. However, the narrow working space and difficulty identifying RPN are problematic. To solve these issues, several studies have used intraoperative ultrasound in endoscopic-assisted transoral surgery. However, the type of ultrasonography suitable for this purpose remains unclear. Case Presentation: A 60-year-old female with thyroid papillary carcinoma (T4aN1bM0 initially underwent total thyroidectomy and paratracheal and selective neck dissections (D2a, with resectional management of recurrent laryngeal nerve, trachea, and esophagus. Three years later, she was diagnosed with left retropharyngeal and upper mediastinal lymph node metastases of papillary thyroid cancer. Transoral videolaryngoscopic surgery was performed with a combination of ultrasonography with a flexible laparoscopic transducer manipulated with forceps for identifying RPN intraoperatively. Due to the transducer’s small size and thin, flexible cable, the transducer interrupted the procedure in spite of the narrowness of oral cavity. RPN was resected completely without adverse events. Conclusion: We performed intraoperative ultrasound-guided endoscopic transoral surgery for metastatic RPN from papillary thyroid cancer and achieved complete resection as well as preservation of swallowing function.

    Full Text Available Diffuse sclerosing papillary thyroid carcinoma (DSPTC is a relatively rare variant of papillary thyroid carcinoma with distinct histological features, radiological characteristics, and biological aggressiveness. Compared with conventional papillary thyroid carcinoma, DSPTC is characterized by scattered microscopic tumor islands, diffuse fibrosis, calcification, and abundant lymphocytic aggregation. A preoperative diagnosis is challenging in the absence of nodules and scanty fine needle aspiration cytology samples. We describe a unique DSPTC patient, an 18-year-old woman who presented with a neck mass that grew slowly for 2 years. The palpable neck mass was nontender, well defined, firm, and unmovable. Laboratory studies showed normal thyroid function and positive autoimmune markers: antithyroglobulin antibody = 1:1600 and antimicrosomal antibody = 1:1600. A neck ultrasound showed diffusely prominent microcalcifications with one small vague nodule. Hashimoto's thyroiditis with an accompanying malignancy was suspected. Based on the result of intraoperative pathology reports, the patient was given a total thyroidectomy. Lymph node dissection and histological analysis revealed bilateral DSPTC in addition to lymphocytic thyroiditis in nonmalignant areas of the thyroid. Clinical and histological diagnostic challenges usually occur when DSPTC presents with a diffuse thyroid enlargement, dispersed microscopic tumor islands (frequently without mass formation, extensive fibrosis, and abundant lymphocytic infiltration mimicking thyroiditis.
