    Adenoid cystic carcinoma (ACC) is a rare variant of adenocarcinoma that usually occurs in the major salivary gland. In breast, adenoid cystic carcinoma is a very rare carcinoma accounting for less than 1% of the all breast carcinoma. It has an excellent prognosis with the lower incidence of distant metastasis and axillary lymph node involvement, and a benign looking or low suspicious findings on imaging. We will report the radiologic and pathologic finding of the adenoid cystic carcinoma that is incidentally detected in the right breast of asymptomatic 47-year-old woman, who had taken annual screening mammogram and ultrasonogram

    We present an 82-year-old male patient who presented with complaints of gradually an increasing ulcero-proliferative lesion with persistent mucinous discharge in the left breast. Left side-modified radical mastectomy was done. This was histopathologically diagnosed as an adenoid cystic carcinoma of the left breast. Periodic acid schiff (PAS) staining confirmed the diagnosis. Three of the five axillary lymph nodes excised were positive for malignancy. Although the patient was advised to have postoperative radiotherapy, he did not comply. After 2 years, the patient again presented with local recurrence of the disease. Wide excision of the recurrent malignant nodules over the anterior chest wall was done, and the defect was covered primarily with split thickness skin grafting. Postoperative radiation was given. For the past 9 months, the patient has maintained a regular follow-up on an outpatient basis. He does not have any evidence of recurrence of the tumor--neither locally nor distant metastasis.

    Adenoid cystic carcinoma is a rare tumour originating from the exocrine mucous glands, known for its high propensity for distant metastases. The value of lung metastasis resection from adenoid cystic carcinoma of salivary glands origin is evaluated. A retrospective study was conducted on patients undergoing surgery for primary adenoid cystic carcinoma of the salivary glands between 1982 and 2006. Patients were excluded who had primary tumour macroscopic incomplete resection or were lost at follow-up. From a database of 50 eligible patients, 27 were identified as having presented a tumour recurrence during follow-up; in 20 it was first diagnosed in the form of distant metastases, and in 7 in the form of loco-regional recurrence. Nine patients who presented isolated lung recurrence underwent complete lung metastasectomy. Demographic data, pathologic characteristics and operative and postoperative record were reviewed, as well as updated survival. Twenty-six men and 24 women with a median age of 57 years (range 33-79) underwent radical surgery for adenoid cystic carcinoma during the study period. In 20 patients, at a median free interval time of 3 years (range 1-12), a distant metastasis relapse was observed. Nine patients with a median free interval time of 5 years (range 1-12) underwent lung metastasectomy: five had single metastasis resection, one multiple mono-pulmonary and three multiple and bilateral. In six of these patients a new disease recurrence was noted: four patients underwent further lung metastasectomy, but in all of them progression of the disease was observed. Mean survival of the population as a whole resulted as being 16 years (SE=1.4) with an actuarial survival of 77% at 5 years, 66% at 10 years and 56% at 15 years. Mean survival of patients having presented with distant metastases resulted as being 11 years (SE=2.2). Mean survival after appearance of distant metastases resulted as being 72 months (SE=15.8) in the 9 patients treated by

    Adenoid cystic carcinoma of the breast is a rare neoplasm, accounting for only 0.1% of all malignant breast tumours. It is more common in women in the sixth decade of their lives and often in the sub areolar area. The clinical criteria is not specific and the radiographic examination showed a benign-appearing tumour. The preoperative diagnosis is possible with fine-needle aspiration cytology. The diagnosis is made by histological examination, presented a difficult differential diagnosis with cribriform carcinoma; so it is necessary to use histochemical or immunohistochemical techniques. The treatment is not well established. It consists of lumpectomy with radiation or mastectomy. Compared to other locations, adenoid cystic carcinoma of the breast has a favorable prognosis. Lymph node involvement or distant metastases seldom occur. The aim of our study is to describe the epidemiological, clinico pathological characteristics, the treatment and the prognosis of this rare type of breast tumour. (authors)

    Basal cell adenoma is a rare type of monomorphic salivary adenoma most commonly involving the parotid gland. Cytology of basal cell adenoma closely mimics many other benign and malignant basaloid neoplasms. Cytological features of membranous basal cell adenoma simulate adenoid cystic carcinoma in fine needle aspiration cytology (FNAC) smears. Here, we are presenting a rare case of cytodiagnosis of membranous basal cell adenoma of parotid gland in an elderly lady, which mimicked adenoid cystic carcinoma on FNAC. We discuss the cytomorphology of this rare case with an emphasis on cytological difference between membranous basal cell carcinoma and adenoid cystic carcinoma as well as other basaloid neoplasms.

    Adenoid cystic carcinoma is a malignant salivary gland tumor with typical histologic patterns. The majority of the se tumors occurs in the minor salivary glands, especially mucosa of the hard palate. The authors experienced the patients, who complained the tumor-like soft tissue masses on the palatal and mouth floor area. After careful analysis of clinical, radiological and histopathological findings, we diagnosed them as adenoid cystic carcinomas in the minor salivary glands, obtained results were as follows : 1. Main clinical symptoms were a slow growing soft tissue mass with normal intact mucosa on the palatal area, and soft tissue mass with mild pain on the mouth floor area. 2. In the radiographic examinations, soft tissue masses were observed with invasion to adjacent structures, and moderate defined, heterogeneous soft tissue mass with enhanced margin, respectively. 3. In the histopathologic examinations, dark-stained, small uniform ballad's cells in the hyaline or fibrous stroma were observed as solid and cribriform patterns, respectively.

    Full Text Available BACKGROUND: The MitoChip v2.0 resequencing array is an array-based technique allowing for accurate and complete sequencing of the mitochondrial genome. No studies have investigated mitochondrial mutation in salivary gland adenoid cystic carcinomas. METHODOLOGY: The entire mitochondrial genome of 22 salivary gland adenoid cystic carcinomas (ACC of salivary glands and matched leukocyte DNA was sequenced to determine the frequency and distribution of mitochondrial mutations in ACC tumors. PRINCIPAL FINDINGS: Seventeen of 22 ACCs (77% carried mitochondrial mutations, ranging in number from 1 to 37 mutations. A disproportionate number of mutations occurred in the D-loop. Twelve of 17 tumors (70.6% carried mutations resulting in amino acid changes of translated proteins. Nine of 17 tumors (52.9% with a mutation carried an amino acid changing mutation in the nicotinamide adenine dinucleotide dehydrogenase (NADH complex. CONCLUSIONS/SIGNIFICANCE: Mitochondrial mutation is frequent in salivary ACCs. The high incidence of amino acid changing mutations implicates alterations in aerobic respiration in ACC carcinogenesis. D-loop mutations are of unclear significance, but may be associated with alterations in transcription or replication.

    (Adenoid cystic carcinoma (ACC) of the breast is a rare type of neoplasm that is histologically indistinguishable from other examples in other sites and generally has a good prognosis). To characterize the clinical and pathological features of ACC in our environment, as well as the treatment offered to our patients, a review of the clinical records of patients treated at the University of Nigeria Teaching Hospital Enugu was undertaken. Case notes of breast cancer patients stored in the medical records department were retrospectively reviewed with a view to studying those with ACC. Follow up on these patients were documented. Adenoid cystic carcinoma of the breast was diagnosed in 9 out of 222 patients treated for cancer of the breast, from 1995-2000. Patients aged 34-70 years were afflicted with this disease. A lump in the breast led to the initial suspicion of a tumor. Some of them had pain in the breast. Many of the patients came with advanced disease. Surgical treatment ranged from simple mastectomy to modified radical mastectomy with radiotherapy and chemotherapy in some patients. The disease is rare at Enugu but contrary to findings elsewhere, majority of our patients had advanced disease. Those with early disease appeared to have a good outcome.

    Adenoid cystic carcinoma (ACC) of the sublingual gland is an extremely rare neoplasm. The clinicopathological characteristics of ACC are slow-growing swelling with or without ulceration, perineural spread, local recurrence, and distant metastasis. This report describes a 58-year-old male who had a slowly growing swelling without ulceration on the right side of the mouth floor that had been present for 1 month. In a radiological examination, the mass showed multilocular cystic features and no bony or tongue muscle invasion. No enlarged cervical lymph nodes were detected. Excisional biopsy and histological analysis showed that the lesion was ACC. In addition to reporting a rare case of ACC, this report also discusses the differential diagnosis and treatment of ACC with a review of the relevant literature.

    2015-01-01

    Full Text Available Adenoid cystic carcinoma (ACC is a rare malignant tumor that affects the major and minor salivary glands, the lacrimal glands, the ceruminous glands and occasionally the excretory glands of the female genital tract. 30-40% of these carcinomas occur in the head and neck region. Approximately 50-70% of the cases have been reported in the minor salivary glands. The most common location is the palate, generally in the area of the greater palatine foramen. ACC is generally characterized by a slow growth rate, and it is often present for several years before the patient seeks treatment. Here we present a case of 42-year-old female who came to the department for the complaint of a swelling over the right side of palate since 2-3 months which was diagnosed as a benign tumor initially, but was confirmed as tubular ACC histologically.

    Adenoid cystic carcinoma is a rare type of breast cancer that is generally reported in individual case reports or as series from major referral centers. To characterize early diagnostic criteria for adenoid cystic carcinoma and to determine whether breast-preserving surgery with radiotherapy is as effective as mastectomy for eradicating the disease, we reviewed clinical records of a large series of patients treated for adenoid cystic carcinoma of the breast at a large health maintenance organization (HMO) that includes primary care facilities and referral centers. Using the data bank of the Northern California Cancer Registry of the Kaiser Permanente Northern California Region (KPNCR), we retrospectively reviewed medical records of patients treated for adenoid cystic carcinoma of the breast. Follow-up also was done for these patients. Adenoid cystic carcinoma of the breast was diagnosed in 22 of 27,970 patients treated for breast cancer at KPNCR from 1960 through 2000. All 22 patients were female and were available for follow-up. Mean age of patients at diagnosis was 61 years (range, 37 to 94 years). In 17 (77%) of the women, a lump in the breast led to initial suspicion of a tumor; in 4 (23%) of the 22 patients, mammography led to suspicion of a tumor. Median tumor size was 20 mm. Pain was a prominent symptom. Surgical management evolved from radical and modified radical mastectomy to simple mastectomy or lumpectomy during the study period, during which time 1 patient died of previous ordinary ductal carcinoma of the contralateral breast, and 7 died of unrelated disease. At follow-up, 12 of the 13 remaining patients were free of disease; 1 patient died of the disease; and 1 patient remained alive despite late occurrence of lymph node and pulmonary metastases. Whether breast-preserving surgery with radiotherapy is as effective as mastectomy for treating adenoid cystic carcinoma of the breast has not been determined.

    2013-01-01

    Full Text Available Adenoid cystic carcinoma (ACC accounts for approximately 6-10% of all salivary gland tumors. Palatal minor salivary glands, parotid, and sub-mandibular glands are usually affected. Rarely, these lesions arising intraosseously have been reported. Mandible is commonly involved than maxilla. The present case is a giant ACC involving the right maxilla. A thorough clinical and radiographic evaluation was performed to assess the involvement of surrounding vital structures along with a meticulous metastatic work-up. Computed tomography showed a giant lesion in maxilla encroaching the left nasal fossa, antrum, buccal space, and oral cavity. No metastasis was noted. Histological evaluation from multiple sites showed both cribriform and solid patterns. Radiotherapy was given as patient did not comply for surgery. Though central ACC is extremely rare, especially in maxilla, it should be included in the differentials for lesions in maxilla. A prompt diagnosis with treatment and long-term follow-up is advised in such cases.

    Adenoid cystic carcinoma (ACC) of the uterine cervix is a rare primary neoplasm of the uterus that occurs in post-menopausal women; its radiological findings have not been described previously. We present the MR findings of a case of ACC. The mass exhibited homogeneous low-signal intensity on T1-weighted images. On T2-weighted images, the mass showed high-signal intensity with a lobulated contour and multiple septum-like internal architectures. It also contained spots of very high-signal intensity, which would represent the mucin in the glandular lumen. The multiple septum-like internal architectures probably represented interglandular fibrous stroma. These MRI findings may be helpful for future diagnoses of ACC of the uterine cervix. (orig.)

    2014-01-01

    Full Text Available Introduction Adenoid cystic carcinoma (ACC is one of the most frequent malignant salivary gland tumors, which commonly affects the minor salivary glands of the mouth and is rare in the nose and paranasal sinuses. In the maxillary sinus, ACC can mimic inflammatory diseases and has a poor prognosis. Objective To report a case of a 50-year-old man with ACC of the maxillary sinus whose clinical findings in the alveolar ridge mimicked an oroantral fistula. Case Report An excisional biopsy was performed and histopathologic analysis revealed ACC. Lung metastases and residual tumor in the maxillary sinus were detected by imaging methods. In view of the poor general health of the patient, no new surgical intervention was performed and he was only treated by radiotherapy and follow-up. Conclusion Although rare in the maxillary sinus, ACC should be included in the differential diagnosis of lesions affecting this site.

    2010-12-01

    Full Text Available Abstract Background Adenoid cystic carcinoma is one of the most common types of salivary gland cancers. The poor long-term prognosis for patients with adenoid cystic carcinoma is mainly due to local recurrence and distant metastasis. Disintegrin and metalloprotease 10 (ADAM 10 is a transmembrane protein associated with metastasis in a number of diverse of cancers. The aim of this study was to analyze the relationship between ADAM 10 and the invasive and metastatic potentials as well as the proliferation capability of adenoid cystic carcinoma cells in vitro and in vivo. Methods Immunohistochemistry and Western blot analysis were applied to detect ADAM 10 expression levels in metastatic cancer tissues, corresponding primary adenoid cystic carcinoma tissues, adenoid cystic carcinoma cell lines with high metastatic potential, and adenoid cystic carcinoma cell lines with low metastatic potential. RNA interference was used to knockdown ADAM 10 expression in adenoid cystic carcinoma cell lines with high metastatic potential. Furthermore, the invasive and metastatic potentials as well as the proliferation capability of the treated cells were observed in vitro and in vivo. Results It was observed that ADAM 10 was expressed at a significantly higher level in metastatic cancer tissues and in adenoid cystic carcinoma cell lines with high metastatic potential than in corresponding primary adenoid cystic carcinomas and adenoid cystic carcinoma cell lines with low metastatic potential. Additionally, silencing of ADAM 10 resulted in inhibition of cell growth and invasion in vitro as well as inhibition of cancer metastasis in an experimental murine model of lung metastases in vivo. Conclusions These studies suggested that ADAM 10 plays an important role in regulating proliferation and metastasis of adenoid cystic carcinoma cells. ADAM 10 is potentially an important therapeutic target for the prevention of tumor metastases in adenoid cystic carcinoma.

    A 57-year-old woman was referred to our institution 4 months after she noticed a palpable, painless mass in her left breast. Physical examination revealed a mobile and elastic mass. An axillary or subclavicular lymph node was not palpable. Mammography revealed a lobulated mass with a partially ill-defined border. Ultrasonography depicted a 2.5 × 1.5 cm irregularly shaped mass with heterogeneous internal echo and posterior acoustic enhancement. The border of the mass was poorly defined at the anterior and lateral aspects of the mass. Results of ultrasonography-guided fine-needle aspiration cytology were strongly suggestive of a malignant tumor. Thus, the patient underwent breast-conserving surgery with axillary lymph node dissection. The gross resected specimen revealed a gray-to-white and well-demarcated solid tumor measuring 3 × 2 × 2.5 cm, with an irregular border and heterogeneous internal structure. Histological examination showed the characteristic patterns of adenoid cystic carcinoma of the breast. Immunohistochemical studies for both estrogen receptors (ER) and progesterone receptors (PgR) were negative. The patient remains well and has no clinical recurrence of the disease after 5 years of follow-up without radiotherapy or adjuvant therapy.

    Full Text Available A 37-year-old male athlete was diagnosed with primary tracheal adenoid cystic carcinoma following investigation for dyspnea, wheeze, and eventual stridor. Preoperative bronchoscopy revealed a highly vascular tumor 4 cm distal to the cricoid with no gross disease extending to the carina. Imaging revealed circumferential tracheal irregularity immediately inferior to the cricoid, with no definite cricoid invasion. Locoregional extension of disease was noted invading the thyroid and abutment of the carotid approximately 180°. Intraoperative findings identified tracheal mucosal disease extending distal to the carina and proximally at the cricothyroid joints where bilateral functional recurrent nerves were preserved. A decision made to preserve the larynx given the inability to fully resect distal tracheal disease. A 5 cm sleeve resection of the trachea was made with a cricotracheal anastomosis following suprahyoidal muscle release and laryngeal drop-down. The patient was treated with adjuvant radiotherapy including platinum based chemotherapy in an effort to maximise local control. PET scanning three months after therapy revealed no FDG uptake locally or distally.

    Adenoid cystic carcinoma (AdCC) is a rare type of triple-negative breast cancer (TNBC) characterized by the presence of the MYB-NFIB fusion gene. The molecular underpinning of breast AdCCs other than the MYB-NFIB fusion gene remains largely unexplored. Here we sought to define the repertoire of somatic genetic alterations of breast AdCCs. We performed whole-exome sequencing, followed by orthogonal validation, of 12 breast AdCCs to determine the landscape of somatic mutations and gene copy number alterations. Fluorescence in situ hybridization and reverse-transcription PCR were used to define the presence of MYB gene rearrangements and MYB-NFIB chimeric transcripts. Unlike common forms of TNBC, we found that AdCCs have a low mutation rate (0.27 non-silent mutations/Mb), lack mutations in TP53 and PIK3CA and display a heterogeneous constellation of known cancer genes affected by somatic mutations, including MYB, BRAF, FBXW7, SMARCA5, SF3B1 and FGFR2. MYB and TLN2 were affected by somatic mutations in two cases each. Akin to salivary gland AdCCs, breast AdCCs were found to harbour mutations targeting chromatin remodelling, cell adhesion, RNA biology, ubiquitination and canonical signalling pathway genes. We observed that, although breast AdCCs had rather simple genomes, they likely display intra-tumour genetic heterogeneity at diagnosis. Taken together, these findings demonstrate that the mutational burden and mutational repertoire of breast AdCCs are more similar to those of salivary gland AdCCs than to those of other types of TNBCs, emphasizing the importance of histological subtyping of TNBCs. Furthermore, our data provide direct evidence that AdCCs harbour a distinctive mutational landscape and genomic structure, irrespective of the disease site of origin.

    Objective: To investigate the clinicopathologic features and grading of adenoid cystic carcinoma (ACC) of the breast. Methods: Sixteen cases of ACC of the breast were analyzed and graded according to the previous report. Immunohistochemical (IHC) staining was used to detect the immunophenotype, Ki-67 proliferative index and expression of EZH2, and the association with tumor grade and outcome was analyzed. Results: Of the 16 cases, 11 were grade Ⅰ, with the epithelial and myoepithelial cells being arranged into tubular and cribriform structure with no solid component; three were grade Ⅱ, which were composed of mixed tubular, cribriform and solid component (90%) and the tumor cells showed basaloid features with scanty cytoplasm and hyperchromatic nuclei, and mitotic count was>5/10 HPF. Immunophenotypically, the epithelial cells expressed CK7, CK8/18 and CD117; the myoepithelial cells expressed p63 and CK5/6; while the basaloid cells were positive for CK5/6 and CD117.Tubular and cibriform ACC showed low Ki-67 and EZH2 expression, while the two cases of solid variant with basaloid features showed high level of Ki-67 and EZH2 expression. Follow-up data were available in 13 cases with a median follow-up period of 42 months. Lung metastasis occurred after 12 months in one grade Ⅱ case and the patient died of disease after 34 months. Vertebral metastasis occurred after 12 months in one grade Ⅲ case and axillary lymph node metastasis occurred in another grade Ⅲ case. All other patients were free of disease at the end of the follow-up periods. Conclusions: ACC shows morphologic spectrum varying from low to high grade, the latter can may give rise to local and distant metastasis. ACC should not be regarded simply as low malignant potential, and should be graded for optimal treatment.

    Adenoid cystic carcinoma of the breast is an uncommon histologic form of breast cancer, comprising in most series less than 1% of all mammary cancers. Due to the rarity, little information about its presentation on image studies has been noted in the literature. Here we report two additional cases with emphasis on the intriguing image presentations. A 67-year-old woman came to our clinic with the chief complaint of mastodynia. No obvious palpable mass of breast was found on physical examination. Mammography showed a small well-defined nodule in the medial part of the left breast without mammographic evidence of malignancy. Ultrasonography showed a 1.5 cm nodule with well-defined margin and heterogenous echogenicity in the medial part of the left breast. Unusually, a painful sensation was experienced on compression by the probe. The final pathological report was adenoid cystic carcinoma. A 48-year-old woman also came to our clinic with the chief complaint of mastodynia. No obvious palpable mass of breast was found on physical examination. Mammography showed dense mammary tissue with no mammographic evidence of malignancy. Ultrasonography showed two contiguous well-defined nodules with heterogenous echogenicity in the upper, middle part of the left breast. Unusually, a painful sensation was also noted on compression by the probe. Histopathological examination showed typical features of an adenoid cystic carcinoma. Adenoid cystic carcinoma of the breast fails to show the typical appearance of invasive ductal carcinoma on both mammogram and ultrasonography, probably due to its relatively well-defined nature with less surrounding architectural disruption and fibrosis. Hence a "negative" finding or a benign-looking breast lesion on mammography cannot completely exclude the existence of this disease. The presence of a painful breast lesion without obvious inflammatory evidence while compressed is a meaningful clue, which should lead to the suspicion of adenoid cystic

    Adenoid cystic carcinoma of salivary glands is a rare adenocarcinoma and has been placed in "high-risk" category as poor long-term prognosis. The purpose of this study was to investigate p53 protein expression in adenoid cystic carcinoma of salivary glands and its correlation with clinicopathological parameters and prognosis. Literatures were searched from PubMed, Embase, Cochrane Library and Web of Science, which investigated the relationships between p53 expression and pathological type, clinical stage, local recurrence, metastasis, nerve infiltration and overall survival. A total of 1,608 patients from 36 studies were included in the analysis. The results showed that p53-postive expression rate was 49% in adenoid cystic carcinoma of salivary glands (OR=10.34, 95%CI: 4.93-21.71, P salivary glands. It can be considered as the auxiliary detection index in treatment and prognosis of adenoid cystic carcinoma of salivary glands.

    Adenoid cystic carcinoma of the breast is a rare malignant neoplasm associated with an excellent prognosis and a very rare occurrence of metastases. We report the case of an aggressive presentation in a 65-year-old woman, of Belgian origin, who was diagnosed as having adenoid cystic carcinoma of the breast and developed metastases to her lung, kidney, and brain. We describe similar cases reported in the literature and discuss the molecular characteristics and treatment paradigm of this controversially aggressive disease entity.

  1. A subset of prostatic basal cell carcinomas harbor the MYB rearrangement of adenoid cystic carcinoma.

    Adenoid cystic carcinoma (ACC) is a basaloid tumor consisting of myoepithelial and ductal cells typically arranged in a cribriform pattern. Adenoid cystic carcinoma is generally regarded as a form of salivary gland carcinoma, but it can arise from sites unassociated with salivary tissue. A rare form of prostate carcinoma exhibits ACC-like features; it is no longer regarded as a true ACC but rather as prostatic basal cell carcinoma (PBCC) and within the spectrum of basaloid prostatic proliferations. True ACCs often harbor MYB translocations resulting in the MYB-NFIB fusion protein. MYB analysis could clarify the true nature of prostatic carcinomas that exhibit ACC features and thus help refine the classification of prostatic basaloid proliferations. Twelve PBCCs were identified from the pathology consultation files of Johns Hopkins Hospital. The histopathologic features were reviewed, and break-apart fluorescence in situ hybridization for MYB was performed. All 12 cases exhibited prominent basaloid histology. Four were purely solid, 7 exhibited a cribriform pattern reminiscent of salivary ACC, and 1 had a mixed pattern. The MYB rearrangement was detected in 2 (29%) of 7 ACC-like carcinomas but in none (0%) of the 5 PBCCs with a prominent solid pattern. True ACCs can arise in the prostate as is evidenced by the presence of the characteristic MYB rearrangement. When dealing with malignant basaloid proliferations in the prostate, recommendations to consolidate ACCs with other tumor types may need to be reassessed, particularly in light of the rapidly advancing field of biologic therapy where the identification of tumor-specific genetic alterations presents novel therapeutic targets.

    Full Text Available We report a known case of adenoid cystic carcinoma of right parotid gland in a 36-year-old Indian male, diagnosed 5 years ago for which he underwent surgery followed by radiotherapy. Now the patient has presented to the surgical oncologist with a mass near angle of right jaw. Computed tomography (CT performed elsewhere was reported negative for local recurrence. Subsequently, 18 F Fluorodeoxyglucose positron emission tomography-CT (FDG PET-CT demonstrated local recurrence in right parotid bed. Surprisingly, metabolically active metastatic skeletal deposits were also identified, thus the disease was upstaged and management was changed. Trucut biopsy from left iliac bone lesion confirmed metastases from adenoid cystic carcinoma. Thus a whole body PET-CT has a significant impact on management of patients with salivary gland malignancies in assessing both local recurrence as well as distant metastases, especially in atypical and unsuspected sites.

    2015-01-01

    Full Text Available Adenoid cystic carcinoma (ACC is a rare neoplasm that usually arises from minor salivary glands. It is characteristically locally infiltrative, exhibiting perineural invasion, has a tendency for local recurrence and prolonged clinical course. A 60 year old male, chronic smoker presented with swelling of the left cervical lymph node since two months. Examination revealed a solitary firm, non tender, non mobile left cervical swelling measuring 2 x 1 cm. Fine Needle Aspiration Cytology (FNAC was done from the cervical lymph node. The diagnosis of metastatic deposits of ACC was given. Detail examination of the oral cavity revealed a small swelling at the floor of the mouth. Biopsy of the swelling confirmed ACC on histopathological examination. An unusual feature of adenoid cystic carcinoma is the low incidence of metastases to regional lymph nodes. The case is presented to highlight its unusual presentation and utility of FNAC in rapid diagnosis.

    We present a case report of an auxiliary nurse who developed an adenoid cystic carcinoma in her left maxillary sinus following occupational exposure to formaldehyde in the operating theatre. Currently, the epidemiological evidence that formaldehyde can cause cancer in humans is considered to be limited. Previous case-control-studies of formaldehyde and sinonasal cancer have mainly investigated subjects who were concomitantly exposed to wood dust, a known risk factor to the development of sinonasal adenocarcinoma of intestinal type. Our case report presents a patient who has developed an adenoid cystic carcinoma following exposure to formaldehyde. We suggest that the occupational physician remains alert to formaldehyde as an occupational hazard among health care workers.

    Full Text Available Adenoid cystic carcinoma (ACC is a rare malignant tumor that affects the head and neck region. It is a malignant tumor arising from minor salivary glands, palate being the most common intraoral location, usually affecting individuals of the fifth decade. This tumor generally has a slow growth rate, and it is often present for several years before the patient seeks treatment. We report a case of extensive ACC involving palate, extending to a maxillary sinus in a young lady.

    Tumor-derived exosomes (TDE) have been shown to participate in different steps of the dissemination of cancer cells. However, the role of salivary adenoid cystic carcinoma-derived (SACC-derived) exosomes had not been documented in SACC. The study aims to explore the functions of SACC-derived TDE in SACC progression and investigate potential mechanisms. Salivary adenoid cystic carcinoma cell line SACC-83 was used to generate TDE. Afterward, SACC-83 or HUVECs were cocultured with or without TDE. Tumor migration, tumor invasion, and endothelial permeability were examined by wound healing assay, tumor invasion assay, endothelial permeability assay, and tumor cell transendothelial migration assay, respectively. Moreover, the expression levels of cell junction-related proteins were examined by qRT-PCR and Western blot. Salivary adenoid cystic carcinoma -83-derived exosomes were taken up by their host cells. Meanwhile, TDE increased migration and invasion capacity of SACC-83 cells and enhanced endothelial cell permeability. Furthermore, we demonstrated that the expression of cell junction-related proteins (Claudins and ZO-1) was downregulated, which is presumably involved in the TDE-mediated promotion of migration, invasion, and metastasis. The results suggested that SACC cell-derived exosomes were loaded with individual components that could enhance invasiveness and induce microenvironment changes, thus promoting SACC aggression. © 2017 John Wiley & Sons A/S.

    Full Text Available Primary adenoid cystic carcinoma (PACC of the skin is a rare tumor with fewer than 70 cases studied in detail in the English literature. This type of tumor shows a prolonged course and a growth pattern usually manifested by multiple local recurrences and has a low potential for distant metastases. The most important modality for primary treatment is surgical resection followed by radiotherapy. We report a woman aged 43 years at the time of diagnosis, who presented with a slow-growing nodule in the right axilla without lymph node enlargement. A wide local excision was performed, and the histology revealed an adenoid cystic carcinoma. During the next 24 years, another four local recurrences were excised (the last one in 2015 and confirmed histologically to be adenoid cystic carcinoma. The patient was given 44 Gy of radiotherapy after the second surgery in 1996. PACC of the skin is a rare tumor with insufficient data concerning the efficacy of the surgical technique and chemotherapy and radiotherapy treatment, even more so in the case of multiple recurrences. After the last recurrence, the patient was offered an active follow-up based on the long tumor-free intervals in the past and because the site of the primary tumor allowed further surgical excisions in future recurrences.

    Adenoid cystic carcinoma of the breast is a rare neoplasm accounting for 0.1% of all malignant breast tumors and presenting most commonly as a painful breast mass. Compared with the more common histological forms of breast cancer, it has a more favorable prognosis and lymph node involvement or distant metastases seldom occur. A unique case of multifocal adenoid cystic carcinoma of the breast presenting as a painful and well-defined lump and treated with conservative surgery with adjuvant radiotherapy is reported. There is no consensus on the optimal management of this disease. A breast-conserving approach may be recommended even if mastectomy has been traditionally the treatment of choice. Chemotherapy, radiation, and hormonal therapy have been infrequently used and so far have had no defined role in this kind of neoplasm. The authors found no other reports in the literature focusing on a conservative approach to multifocal adenoid cystic carcinoma.

    Full Text Available Adenoid cystic carcinoma (ACC is one of the most common malig¬nancy in secretory glands. It accounts for about 15% -25% of all malignant salivary gland carcinomas. Typically, ACC is slow growing tumors and develops distant metastasis via haematogenous. We report a case who presented with respiratory failure and multiple metastases. A 52-year-old male, underwent a radical craniofacial resection for a right parotid gland, followed by postoperative radiotherapy. He was followed-up with head CT scans for 5 years with no signs of locoregional recurrence. Physical examination was normal. Blood gases analyses showed moderate hypoxemia. pH; 7,49 pCO2; 31,8 Po2; 38,9 HCO3; 24,1 sat O2; 79,1. Thorax CT showed multiple lesions ranging in size from 5 mm to 4 cm distributed diffusely in both lungs. CT-guided fine-needle aspiration of the lung lesion was performed. Pathological analysis reported adenoid cystic carcinoma. Multiple pulmonary metastases may cause respiratory failure and requires constant vigilance by medical practitioners.

    Adenoid cystic carcinoma (ACC) of the salivary glands has a poor long-term prognosis and high metastatic rate. Toll-like receptors (TLRs) have been related to tumour progression but have also tumour growth-inhibiting responses. To the best of our knowledge, they have not been studied previously in ACC. We studied the immunoexpression of TLR 5 and 7 in ACC of the major salivary glands. From a cohort of 54 patients with ACC of the major salivary glands treated at the Department of Otorhinolaryngology-Head and Neck Surgery, Helsinki University Hospital, Helsinki, Finland in 1974-2009, there were 34 primary tumours and six metastases available for immunohistochemical analysis. Immunohistochemical expression of TLR 5 and 7 were correlated to clinicopathological findings and patient survival. Both TLR 5 and 7 were expressed in ACCs and their metastases, mostly on the cell membranes. The expression was heterogeneous in individual tumours. TLR 5 was expressed less in male samples, and TLR 7 had lower expression in ACCs with solid growth pattern. No correlation with survival was found. In the normal salivary gland, the TLR 5 and 7 expression was mainly negative. Both TLR 5 and 7 are expressed in salivary adenoid cystic carcinoma on the cell membranes as well as in cytoplasm.

  13. Management of salivary gland adenoid cystic carcinoma: institutional experience of a case series

    Directory of Open Access Journals (Sweden)

    Alfio José Tincani

    Full Text Available CONTEXT AND OBJECTIVE: Salivary gland tumor management requires long-term follow-up because of tumor indolence and possible late recurrence and distant metastasis. Adenoid cystic carcinoma (ACC accounts for 10-15% of such tumors. The aim here was to evaluate surgical and clinical management, staging and follow-up of ACC patients in one academic institution. DESIGN AND SETTING: Retrospective study at Head and Neck Service, Universidade Estadual de Campinas. METHODS: Data on 21 patients treated between 1993 and 2003 were reviewed. Management utilized clinical staging, histology and imaging. Major salivary gland tumor extent was routinely assessed by preoperative ultrasonography. Diagnosis, surgery type, margin type (negative/positive, postoperative radiotherapy and recurrence (presence/absence were evaluated. RESULTS: There were eleven major salivary gland tumors (52.3%, seven submandibular and four parotid. Ten patients (47.7% had minor salivary gland ACC (all in palate, while the submandibular was the most frequently affected major one. Diagnoses were mostly via fine-needle aspiration (FNA and incision biopsy. Frozen sections were used for six patients. There was good ultrasound/FNA correlation. Sixteen (76% had postoperative radiotherapy. One (4.7% died from ACC and five now have recurrent disease: three (14.2% locoregional and two (9.5% distant metastases. CONCLUSION: Adenoid cystic carcinoma has locally aggressive behavior. In 21 cases, of ACC, the facial nerve was preserved in all except in the few with gross tumor involvement. Treatment was defined from physical examination, imaging, staging and histology.

    Adenoid cystic carcinoma (ACC) of the breast is a very rare and indolent tumor with a favorable prognosis, despite its triple-negative status. Due to its rarity, there has been no consensus regarding treatments, and treatment guidelines have not been established. Here, we report on six patients with ACC of the breast. All of the patients initially presented with localized disease and no axillary lymph node metastases. Although some of our patients developed local recurrence or distant metastases, all patients had a favorable clinical course, and to date, none of the patients has died from complications of her disease. Here, we described the clinicopathologic features of ACC of the breast and review the current literature.

    Full Text Available Adenoid cystic carcinoma (AdCC is a malignant neoplasm, which accounts for 5-10% of all salivary gland tumors (1. About 50% of these tumors originate from intraoral minor salivary glands usually in the hard palate (1. Three clinically obvious characteristics of AdCC include slow growth rate, perineural invasion and high incidence of distant metastasis (1. The most commonly-affected sites of distant metastasis are bone, liver and brain, followed by lungs (2. Lymph node metastases are rare;  The most common sites  involved by hematogenous spread are lungs (2.  This is a report about a patient with a rare form of AdCC on buccal mucosa with an unusual metastasis to the frontal region after a two-year follow up.

    Full Text Available ABSTRACTPrimary cutaneous adenoid cystic carcinoma (PCACC is a rare malignant epithelial tumor most commonly observed in the scalp and skin of the chest and originating from the palpebral portion of the lacrimal gland in the orbit. Here we describe the diagnosis and treatment of a rare case of PCACC in an eye of a 52-year-old male. The patient presented with a mass lesion of the right lower eyelid. During incisional biopsy, lack of encapsulation and a secretion pattern different to that of chalazion was observed, which differentiated the lesion from chalazion. Pathological analysis revealed the diagnosis of PCACC. This case highlights the importance of careful inspection for macroscopic differentiation of PCACC from chalazion after initial surgery and pathological evaluation of all surgically removed mass lesions for accurate diagnosis and treatment.

    Adenoid cystic carcinoma (ACC) is a subtype of adenocarcinoma that is usually seen in the salivary glands. It has also been reported in other organs including the breast, skin, tracheobronchial tree, cervix, larynx, and Bartholin gland. ACC in the breast is rare, accounting for less than 0.1% of all breast cancers. Furthermore, the imaging characteristics of ACC of the breast have not been well described in the literature, especially regarding the findings with magnetic resonance imaging (MRI). Here, we report radiologic findings of a rare case of ACC in the breast by mammography, sonography, computed tomography (CT), positron emission tomography/CT, and MRI with pathologic correlation and a review of the literature.

    Translocation events are frequent in cancer and may create chimeric fusions or 'regulatory rearrangements' that drive oncogene overexpression. Here we identify super-enhancer translocations that drive overexpression of the oncogenic transcription factor MYB as a recurrent theme in adenoid cystic carcinoma (ACC). Whole-genome sequencing data and chromatin maps highlight distinct chromosomal rearrangements that juxtapose super-enhancers to the MYB locus. Chromosome conformation capture confirms that the translocated enhancers interact with the MYB promoter. Remarkably, MYB protein binds to the translocated enhancers, creating a positive feedback loop that sustains its expression. MYB also binds enhancers that drive different regulatory programs in alternate cell lineages in ACC, cooperating with TP63 in myoepithelial cells and a Notch program in luminal epithelial cells. Bromodomain inhibitors slow tumor growth in ACC primagraft models in vivo. Thus, our study identifies super-enhancer translocations that drive MYB expression and provides insight into downstream MYB functions in alternate ACC lineages.

    To detect MYB gene breaks in adenoid cystic carcinoma (ACC) of the salivary glands and its correlation with prognosis and selected clinical parameters MYB gene break was detected by FISH assay in 23 adenoid cystic carcinomas using formalin-fixed paraffin-embedded blocks. The Kaplan-Meier survival analysis was used to estimate prognosis. Fifteen of 23 evaluated tumours were MYB positive and 8 MYB negative. The 10-year cumulative survival, respectively disease free interval, was 60.0%, respectively 59.3%, in MYB positive patients and 88.5%, respectively 80.0%, in MYB negative patients (long rank test, P=0.23). There were no significant differences in age, gender, perineural invasion, the presence of hematogenic or nodal metastases or degree of histopathological grading between MYB positive and MYB negative patients. A tendency to differences in the survival of patients with ACC, depending on their MYB status. MYB negative patients were predisposed to better prognosis.

    Full Text Available Abstract Background ERBB3 binding protein 1 (EBP1 gene transfer into human salivary adenoid cystic carcinoma cells has been shown to significantly inhibit cell proliferation and reduce tumor metastasis in mouse models. In the current study, to evaluate if EBP1 is a novel biomarker capable of identifying patients at higher risk of disease progression and recurrence, we examined the EBP1 expression profile in adenoid cystic carcinoma (ACC patients and analyzed its clinicopathological relevance. To understand the underlying anti-metastatic mechanism, we investigated if EBP1 regulates invasion-related molecules. Methods We performed immunohistochemical analysis on 132 primary adenoid cystic carcinoma and adjacent non-cancerous tissues using commercial EBP1, MMP9, E-cadherin and ICAM-1 antibodies. Results were correlated to clinicopathological parameters, long-term survival and invasion-related molecules by statistical analysis. Cell motility and invasiveness of vector or wild-type EBP1-transfected ACC-M cell lines were evaluated using wound healing and Boyden chamber assays. MMP9, E-cadherin and ICAM-1 proteins in these cell lines were detected using western blot assay. Results The expression of EBP1 was significantly higher in non-cancerous adjacent tissues compared with corresponding cancer tissues. The intensity and percentage of cells that reacted with EBP1 antibodies were significantly higher in cases with tubular pattern than those with solid pattern (PPPPPP=0.0002. Conclusions EBP1 expression is reduced in adenoid cystic carcinoma, indicating unfavorable prognosis of ACC patients. Its regulation of MMP9 and E-cadherin protein levels suggests a critical therapeutic potential.

    To explore the clinical features, management approach and treatment outcomes for adenoid cystic carcinoma (ACC) of the breast. The clinicopathological data of 25 patients with breasts ACC treated in our hospital from years 1990 to 2012 were retrospectively reviewed and their prognosis was analyzed. The median age of these 25 patients was 53 years (ranged from 31 to 81 years). With the exception of one male case, all patients were female including 17 cases of postmenopausal women. The most frequent presenting symptom is breast lumps, most (48.0%) were in the upper outer quadrant and areola area of the breast. Core needle biopsy was performed in five patients. The specimen finding were adenoids in three and invasive carcinoma in two cases. Axillary lymph node dissection was performed in 23 patients. Only two patients had histologically positive lymph nodes (3 of 14 and 2 of 20). Expression of ER and PR in 14 cases was detected by immunohistochemistry, showing one PR-positive and three ER-positive cases. The median follow-up of the 25 cases was 118 months (ranged from 12 to 244 months). Two patients died of lung metastases at 3 and 10 years after the surgery, respectively. Due to the complexity of the histology of ACC, adequate sampling of specimens is essential for accurate diagnosis. ACC of the breast is a rare disease with a relatively good prognosis. The low incidence of axillary lymph node metastasis suggests that axillary node dissection is not recommended as a routine procedure. Breast ACC are often with negative ER and PR expression, and the value of adjuvant therapy needs to be further investigated.

    Adenoid cystic carcinoma is among the most frequent malignancies in the salivary and lacrimal glands and has a grave prognosis characterized by frequent local recurrences, distant metastases, and tumor-related mortality. Conversely, adenoid cystic carcinoma of the breast is a rare type of triple......-negative (estrogen and progesterone receptor, HER2) and basal-like carcinoma, which in contrast to other triple-negative and basal-like breast carcinomas has a very favorable prognosis. Irrespective of site, adenoid cystic carcinoma is characterized by gene fusions involving MYB, MYBL1, and NFIB, and the reason...... for the different clinical outcomes is unknown. In order to identify the molecular mechanisms underlying the discrepancy in clinical outcome, we characterized the phenotypic profiles, pattern of gene rearrangements, and global microRNA expression profiles of 64 salivary gland, 9 lacrimal gland, and 11 breast...

    Adenoid cystic carcinoma (ACC) is an uncommon type of breast cancer. There are limited data about its epidemiology, tumor characteristics, and outcomes. Using a large, population-based data base, this study aimed to identify specific characteristics of patients with adenoid cystic breast cancer, investigate its natural history, and determine its long-term prognosis. The California Cancer Registry, a population-based registry, was reviewed from the years 1988 to 2006. The data were analyzed with relation to patient age, tumor size and stage, and overall survival. Relative cumulative actuarial survival was determined using the Berkson-Gage life table method. A total of 244 cases of invasive adenoid cystic cancer were identified in women during this time period. The patients' median age was 61.9 years. Most cases were diagnosed in non-Hispanic White women (82%, n = 200), followed by African American (6%, n = 15), Asian/Pacific-Islander (5.7%, n = 14) and Hispanic women (4.4%, n = 12). The remainder of the patients was of unknown or other ethnicity. Tumors were between 1 and 140 mm in size. At the time of diagnosis, 92% (n = 225) of patients had localized disease, 5% (n = 12) of patients had regional disease, and even fewer (n = 7) had either distant or unknown staged disease. Lymph node involvement was not present in any tumors smaller than 1.4 cm. The relative cumulative survival of patients with adenoid cystic breast carcinoma was 95.6% at 5 years and 94.9% at 10 years. ACC of the breast is a rare disease with an overall good prognosis. Knowing that this cancer usually presents as localized disease, with lymph node involvement seen only with larger tumors, can help clinicians plan the operative management of these tumors. © 2011 Wiley Periodicals, Inc.

    Recent biological studies have classified breast carcinomas into HER2-overexpressing, estrogen receptor-positive/luminal, basal- and normal-like groups. According to this new biological classification, the objectives of our study were to assess the clinical, morphologic and immunophenotypic characteristics of adenoid cystic carcinoma of the breast in order to classify this subtype of breast carcinoma. A total of 18 cases of adenoid cystic carcinoma were identified from the Institut Curie files. Clinical information was available for 16 patients with a median follow-up of 6.5 years. Morphologically, all tumors were graded according to the system defined by Kleer and Oberman (histologic and nuclear grade). Immunophenotype was assessed with anti-ER, PR, HER-2, KIT, basal (CK5/6) and luminal cytokeratins (CK8/18) and p63 antibodies. One out of 18 tumors was nuclear grade 1 (16%), nine were nuclear grade 2 (50%) and eight were nuclear grade 3 (44%). All cases were estrogen receptor, progesterone receptor and HER-2 negative. Epithelial cells were strongly positive around glandular lumina with one or both cytokeratins, identifying the coexistence of CK5/6+ cells, CK5/6 and CK8/18+ cells, CK8/18+ cells and p63+ cells. All cases (100%) were also KIT positive. In all, 15 patients were treated by surgery. Nine of them received adjuvant radiotherapy. Follow-up was available for 16 patients. In all, 14 patients were alive. Two of them, initially treated by surgery only, presented a local recurrence. Two patients died (one of them treated by radiation therapy only died from her disease). Our study shows that adenoid cystic carcinoma of the breast is a special, estrogen receptor, progesterone receptor, HER-2 negative and highly KIT-positive, basal-like breast carcinoma, associated with an excellent prognosis. This highly specific immunophenotype could be useful to differentiate adenoid cystic carcinoma of the breast from other subtypes of breast carcinoma such as cribriform

    To explore the expression of hepatitis B-virus X gene (HBX) in adenoid cystic carcinoma (ACC) and determine its clinical significance. Between June 2008 and October 2012, in-hospital patients with salivary gland tumors who were treated at the Department of Oral and Maxillofacial Surgery, Affiliated Stomatology Hospital of Kunming Medical University, were enrolled to this study. HBeAb-positive patients were defined as those exposed to hepatitis B virus (HBV) or harboring persistent HBV infection regardless of being HBeAg positive or negative. According to the pathological results, all patients were divided into ACC group and control group. Immunohistochemical staining and polymerase chain reaction (PCR) were used to detect HBX expression in ACC group and control group. HBX expression was mostly detected in the cytoplasm of ACC cells. Minimal HBX expression was detected in the nucleus. HBX expression was significantly higher in ACC than in Warthin's tumor. A significant difference was observed between the two groups. HBX is expressed in ACC and may be associated with the development of ACC. HBX might serve important functions in the carcinogenesis and development of ACC.

    Full Text Available Adenoid cystic carcinoma (ACC is one of the most common salivary gland malignant tumors with a high risk of recurrence and metastasis. Current studies on cancer stem cells (CSCs have verified that CSCs are the driving force behind tumor initiation and progression, suggesting that new cancer therapies may be established by effectively targeting and killing the CSCs. The primary goal of this study is to investigate the expression patterns of ABCG2, CD133, and podoplanin in ACC of minor salivary glands by immunohistochemistry analysis. We found that ABCG2 was weakly expressed in normal looking salivary gland tissues. A significant upregulation of ABCG2 expression in ACC was observed with a similar expression pattern of Ki-67. CD133 was detected in apical membrane of epithelial cells and podoplanin was expressed positively in myoepithelial cells of both normal looking tissue and ACC. However, no significant difference was found of the expression pattern of CD133 and podoplanin between normal looking tissues and ACC. Our observations suggest that CSCs may exist in quiescent cells with ABCG2 positive staining, which are surrounded by cells with positive expression of ABCG2 and Ki-67 in ACC, and costaining with ABCG2 and Ki-67 may help predict the location of CSCs.

    We performed a retrospective review of patients with nonresected head and neck adenoid cystic carcinoma (ACC) treated with concurrent chemoradiation. Sixteen patients (nasopharynx 7, oropharynx 4, trachea 3, oral and nasal cavity 1 each) were treated at 3 tertiary care centers. Six patients received intraarterial cisplatin and 10 received intravenous cisplatin or carboplatin concurrently with radiation. Thirteen patients are alive, 7 without signs of disease with a median follow-up of 61 months. Tumor progression was noted in 8 patients (50%) (distant metastasis in 5 patients and local tumor progression in 3 patients) with a median time to progression of 25 months (range, 4-52 months). Overall survival (OS), progression-free survival (PFS), and local progression-free survival (LPFS) rates at 5 years were 87%, 39%, and 61%, respectively. Concurrent chemoradiation is a feasible treatment option and may lead to sustained locoregional tumor control in patients with nonresected ACC of the head and neck.

    Adenoid cystic carcinoma of the breast (ACCB) is a rare malignancy with favorable prognosis: axillary lymph node involvement, distant metastases, and death due to disease are uncommon. ACCB may recur locally many years after primary surgical excision and may be substantially higher if primary procedure is lumpectomy rather than mastectomy. Pathology database searched to identify patients diagnosed with ACCB between 1988 and 2007 at Hamilton Health Sciences Centre, Hamilton, Ontario, Canada.Two pathologists independently reviewed histology to confirm diagnosis of ACCB, and documented surgical procedure, tumor size, tumor grade, surgical margin, and lymph node status. Immunohistochemistry was performed on representative blocks and independently reviewed by 2 pathologists. Clinical and radiologic data were retrospectively reviewed. Fifteen cases of ACCB were identified and pathology slides were available for 12. The median age was 62 years. Seven patients presented with a palpable mass and breast pain was described in 3. Positive surgical margins were identified in 5 patients (42%). Only 3 patients had postoperative radiation therapy. Our series shows frequent resection margin involvement in ACCB. Neither clinical nor mammographic examination consistently delineated full tumor extent preoperatively. Future use of magnetic resonance imaging in preoperative assessment may prevent high positive margin rate when lumpectomy is planned. Histologic assessment of tumor extent may be difficult, but immunohistochemistry may be helpful in this regard.

    The role of adjuvant radiation therapy (RT) for adenoid cystic carcinoma (ACC) of the breast remains unclear. We queried the Surveillance, Epidemiology, and End Results database for patients with breast ACC resected between 1988 and 2005, and divided patients based on the receipt of RT. Univariate and multivariate survival comparisons were made for overall and disease-specific survival. Three hundred seventy six patients met criteria for inclusion. Demographics and staging were similar between groups. Univariate analysis revealed an absolute overall and cause-specific survival benefit of 21% and 7% at 10 years (P = 0.005 and P = 0.12 respectively). In the multivariate analysis, RT was a significant predictor of overall and cause-specific survival with hazard ratios of 0.44 (95% Confidence interval (CI) = 0.22-0.88) and 0.1 (95% CI: 0.01-0.88), respectively. RT after local surgical therapy for ACC of the breast improved both cause-specific and overall survival. Use of RT in this rare tumor should be considered in patients otherwise eligible for RT.

    Intracranial involvement by adenoid cystic carcinoma (ACC) is very rare and there is no report of intracranial extension from the palate ACC in Korea. Intracranial involvement can occur in one of three ways: direct extension, perineural spread, and hematogenous spread. A case report of a 35-year-old woman with intracranial ACC is presented. Initially she had ACC of the right palate and was treated by surgery and postoperative radiation therapy. Three years and 10 months later, the paresthesia in the distribution of ophthalmic and maxillary branch of right trigeminal nerve developed without evidence of recurrence in CT scan. Ptosis and total ophthalmoplegia developed sequentially and the second operation was performed. It was suggested that the tumor was spread perineurally along the trigeminal nerve into the Gasserian ganglion and then cavernous sinus and orbit. Seven years and 6 months after the first operation, direct intracranial extension into the right temporal lobe developed via sphenoid bone, sphenoid sinus and temporal bone and the third operation was done. And then Jung metastasis was diagnosed. She is alive for 9 years 5 months after first operation.

    Adenoid cystic carcinoma (AdCC) is a malignant epithelial neoplasm that occurs rarely in the lower respiratory tract (LRT). AdCC at various sites is associated with the novel fusion transcript MYB-NFIB, along with the overexpression of the Myb protein. The expression of the Myb protein in AdCC of the LRT has not been evaluated much. Cases of AdCC of the LRT diagnosed on cytology or histology were retrieved from our institutional archives. c-Myb expression was analyzed on immunocytochemistry/immunohistochemistry (ICC/IHC) and was correlated with clinicopathological parameters. Twenty-three samples of AdCC originating from the LRT were included in the study. Four cases were diagnosed on cytology, 3 of which had corresponding histology specimens. The remaining 19 cases had either biopsy or resection. Most of the patients presented with endobronchial mass. The mean age was 49.4 years and a male predominance was seen. ICC and IHC for c-Myb showed positivity in 75 and 59% of the cases, respectively. Western blot was used to validate IHC results. AdCC of the LRT is rare and hence poses diagnostic difficulty. Cytology smears can be utilized for c-Myb ICC. The presence of c-Myb immunopositivity in most cases may possibly make Myb a diagnostic biomarker and a therapeutic target for personalized treatment. © 2016 S. Karger AG, Basel.

    Cystic adenoid carcinoma or cylindroma of the breast is a rare tumour, and until new only 140 cases have been described in the literature. The clinical criteria are not very specific: tumour in a woman of 50 years of age, with slow growth, unilateral, well delimited, firm, peri-areolar, painless and not adherent to the skin nor the deep tissues. The diagnosis is made by histological examination which shows the presence of pseudo-cysts encased in cellular masses heaped up, composing epithelium and myo-epithelial elements. These are sometimes visible with optic microscopy, and if necessary confirmed by electron microscopy and using immunohistochemical techniques. It is now realised that the myo-epithelial cell plays a role in the histogenesis of the cylindroma. The outcome is usually good after simple surgical removal which has to be sufficient to avoid local recurrences. All the same there have been rare cases of metastases in the literature which means that these cases should be followed up carefully.

    Full Text Available Introduction. The nonsquamous carcinomas of the larynx are considered rare with the majority of malignant tumors in this area, reaching the rate of 95%, to be squamous cell neoplasms. Case Report. The case refers to a 53-year-old man that presented with symptomatology of motor nerve disease. During the evaluation of the neurologic disease, a subglottic mass of the larynx was revealed accidentally in the imaging examination. Under general anesthesia, we performed direct laryngoscopy and biopsy of the mass. The histopathologic examination revealed a hybrid carcinoma coexistence of two different carcinomas, an adenoid cystic carcinoma and an adenocarcinoma, not otherwise specified with poor differentiation. Regarding the therapeutic plan, the mass was considered inoperable due to its expansion to trachea and the patient received radiotherapy. Conclusions. Both the adenocarcinoma and adenoid cystic carcinoma are extremely rare types of malignant tumors in the larynx. The special interest of the present case is the coexistence of these two rare tumors in the same region of the larynx, being a hybrid tumor of the salivary glands in the larynx, which is the second reported case, based on our systematic literature review.

    Full Text Available Abstract Background The metastatic ability of tumor cells is determined by level of expression of specific genes that may be identified with the aid of cDNA microarray containing thousands of genes and can be used to establish the expression profile of disease related genes in complex biological system. Materials and Methods Salivary adenoid cystic carcinoma cell line and its high metastases adenoid cystic carcinoma clone were used as model systems to reveal the gene expression alteration related to metastasis mechanism by cDNA microarray analysis. The correlation of metastatic phenotypic changes and expression levels of 4 selected genes (encoding CD98, L6, RPL29, and TSH were further validated by using RT-PCR analysis of human tumor specimens from primary adenoid cystic carcinoma and corresponding metastasis lymph nodes. Results Of the 7,675 clones of known genes and expressed sequence tags (ESTs that were analyzed, 30 showed significantly different (minimum 3 fold expression levels in two cell lines. Out of 30 genes found differentially expressed, 18 were up regulated (with ratio more than 3 and 12 down regulated (with ratio less than 1/3. Conclusion Some of these genes are known to be involved in human tumor antigen, immune surveillance, adhesion, cell signaling pathway and growth control. It is suggested that the microarray in combination with a relevant analysis facilitates rapid and simultaneous identification of multiple genes of interests and in this study it provided a profound clue to screen candidate targets for early diagnosis and intervention.

    Background: Mammary adenoid cystic carcinoma (ACC) is a rare breast cancer. The aim of this retrospective study was to assess prognostic factors and patterns of failure, as well as the role of radiation therapy (RT), in ACC. Methods: Between January 1980 and December 2007, 61 women with breast ACC were treated at participating centers of the Rare Cancer Network. Surgery consisted of lumpectomy in 41 patients and mastectomy in 20 patients. There were 51(84%) stage pN0 and 10 stage cN0 (16%) patients. Postoperative RT was administered to 40 patients (35 after lumpectomy, 5 after mastectomy). Results: With a median follow-up of 79 months (range, 6-285), 5-year overall and disease-free survival rates were 94% (95% confidence interval [CI], 88%-100%) and 82% (95% CI, 71%-93%), respectively. The 5-year locoregional control (LRC) rate was 95% (95% CI, 89%-100%). Axillary lymph node dissection or sentinel node biopsy was performed in 84% of cases. All patients had stage pN0 disease. In univariate analysis, survival was not influenced by the type of surgery or the use of postoperative RT. The 5-year LRC rate was 100% in the mastectomy group versus 93% (95% CI, 83%-100%) in the breast-conserving surgery group, respectively (p = 0.16). For the breast-conserving surgery group, the use of RT significantly correlated with LRC (p = 0.03); the 5-year LRC rates were 95% (95% CI, 86%-100%) for the RT group versus 83% (95% CI, 54%-100%) for the group receiving no RT. No local failures occurred in patients with positive margins, all of whom received postoperative RT. Conclusion: Breast-conserving surgery is the treatment of choice for patients with ACC breast cancer. Axillary lymph node dissection or sentinel node biopsy might not be recommended. Postoperative RT should be proposed in the case of breast-conserving surgery.

    Provirus integration site for Moloney murine leukemia virus 1 (Pim-1) has proved to be an oncogene and it is known that to depress Pim-1 activity may be a novel oncological treatment strategy. SGI-1776, a small molecule, is the first clinically tested inhibitor of the Pim kinase family. Here, we aimed to explore the effect of SGI-1776 on salivary adenoid cystic carcinoma (SACC). Expression of Pim-1 was confirmed in SACC and control tissues by qRT-PCR. After SGI-1776 treatment, the Pim-1 expressions and Pim-1 kinase activity in both SACC-83 and SACC-LM cell lines were measured. Cell proliferation, cell invasion, cell cycle, apoptosis and mitochondrial membrane potential were analyzed. Also, the expression of FOXO3a, p-FOXO3a, RUNX3, Bcl-2, BAD, p-BAD, Bim and p-Bim were detected by Western blot. The results showed that Pim-1 was significantly overexpressed in SACC tissues. SGI-1776 down-regulated the Pim-1 expression, inhibited Pim-1 kinase activity, reduced cell proliferation, decreased invasive ability, increased caspase-3 activity and induced apoptosis, cell cycle arrest and mitochondrial depolarization. Reduced expression was also seen in p-FOXO3a, RUNX3, Bcl-2, p-BAD and p-Bim, whereas no significant changes were observed from FOXO3a, BAD and Bim. These results confirm the pivotal role of Pim-1 in SACC and suggest that targeting Pim-1 kinase signal pathway by SGI-1776 might be a promising therapeutic modality for SACC.

    Adenoid cystic carcinoma (ACC) of the head and neck is a rare malignancy of salivary gland origin. Few epidemiologic studies exist assessing the incidence of this tumour. The purpose of the current study was to determine the incidence of ACC of the head and neck in Nova Scotia. Furthermore, we assessed survival outcomes based on presentation sites. Nova Scotia is an ideal geographic location in which to conduct retrospective case reviews as there are centralized tertiary care centres and minimal population migration. Furthermore, there is an externally and internally validated cancer registry housed in Cancer Care Nova Scotia. Records at Cancer Care Nova Scotia were retrospectively reviewed to identify all reported cases of ACC since 1979. Age-adjusted incidence rates were calculated standardized to the 2001 Canadian population. Survival curves were plotted to allow assessment of overall survival. A log-rank test was used to compare survival curves for age (> 65 and Nova Scotia is 4.5 (0.6) cases per 1 000,000. The incidence did not change significantly over time. The most common site of presentation was the minor salivary glands (40%), followed by the submandibular gland (18.2%) and the parotid gland (17.3%). There was no significant difference for overall and disease-free survival between nonsalivary, major salivary, and minor salivary tumours (p = .97). Significant reductions in survival were found for those diagnosed at > 65 years of age (p < .014) and those with a sinus presentation (p < .005). Sixteen percent of all head and neck cancer patients experienced a distant metastasis of their primary tumour. ACC of the head and neck is a rare neoplastic condition that most commonly affects the minor and major salivary glands. Although short-term survival is high, nearly half of all patients will develop metastasis or die of complications of local recurrences.

    This study aimed to evaluate and compare the immunoexpression of glucose transporter-1 (GLUT-1) and angiogenic index between pleomorphic adenomas (PAs), adenoid cystic carcinomas (ACCs), and mucoepidermoid carcinomas (MECs) of the salivary glands, and establish associations with the respective subtype/histological grade. Twenty PAs, 20 ACCs, and 10 MECs were submitted to morphological and immunohistochemical analysis. GLUT-1 expression was semi-quantitatively evaluated and angiogenic index was assessed by microvessel counts using anti-CD34 antibody. Higher GLUT-1 immunoexpression was observed in the MECs compared to PAs and ACCs (p = 0.022). Mean number of microvessels was 66.5 in MECs, 40.4 in PAs, and 21.2 in ACCs (p GLUT-1 expression and angiogenic index showed no significant correlation in the tumors studied. Results suggest that differences in biological behavior of the studied tumors are related to GLUT-1. Benign and malignant salivary gland tumors differ in the angiogenic index; however, angiogenesis may be independent of the tumor cell's metabolic demand.

    Full Text Available Abstract Background Adenoid cystic carcinomas are rare tumors with an indolent clinical course, but frequent local relapses. The identification of tumors with a higher relapse risk seems to be interesting. Hence we investigated parameters of glucose metabolism, which were found associated with poor prognosis in other malignancies. Methods Specimen of 29 patients were investigated immunohistochemically with antibodies against p-AKT, TKTL-1 (transketolase-like 1, M2PK (M2 pyruvate kinase, and GLUT-1. Proliferation was investigated by staining with Ki67. The tumors were located at the major or minor salivary glands. Only the typical cribriform subtype was investigated. The initial tumor stage was pT1 or pT2. Results Expression of p-AKT was significantly (P = 0.036 associated with a higher relapse risk in multivariate analysis. Low expression of M2PK was non-significantly (P = 0.065 predictive for a higher risk. TKTL-1 and GLUT-1 were expressed in the majority of cases, albeit not associated with relapse risk. Conclusion Adenoid cystic carcinomas positive for p-AKT show a higher relapse risk. However, other parameters of glucose metabolism investigated here or proliferation (Ki67 were not predictive in this entity. Our findings demonstrate a possible background for therapeutic approaches targeting the inhibition of PI3K/AKT pathway.

    Salivary gland adenoid cystic carcinoma (ACC) is rare, aggressive, and challenging to treat. Many ACCs have a t(6;9) chromosomal translocation resulting in a MYB-NFIB fusion gene, but the clinical significance is unclear. The purposes of this study were to describe the clinicopathologic factors impacting survival and to determine the prevalence and clinical significance of MYB-NFIB fusion. Case series. Medical records of patients treated for ACC of the head and neck from 1974 to 2011 were reviewed and clinicopathologic data recorded. Fluorescence in situ hybridization (FISH) was used to detect MYB rearrangement in archival tumor tissue as a marker of MYB-NFIB fusion. One hundred fifty-eight patients were included, with median follow-up 75.1 months. Median overall survival was 171.5 months (95% confidence interval [CI] = 131.9-191.6), and median disease-free survival was 112.0 months (95% CI = 88.7-180.4). Advanced stage was associated with decreased overall survival (adjusted ptrend  MYB-NFIB fusion. MYB-NFIB positive tumors were more likely than MYB-NFIB negative tumors to originate in minor salivary glands (adjusted prevalence ratios = 1.51, 95% CI = 1.07-2.12, P = 0.019). MYB-NFIB tumor status was not significantly associated with disease-free or overall survival (hazard ratio [HR] = 1.53, 95% CI = 0.77-3.02, P = 0.22 and HR = 0.91, 95% CI = 0.46-1.83, P = 0.80, respectively, for MYB-NFIB positive compared with MYB-NFIB negative tumors). Stage and margin status were important prognostic factors for ACC. Tumors with evidence of MYB-NFIB fusion were more likely to originate in minor salivary glands, but MYB-NFIB tumor status was not significantly associated with prognosis. 4. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    PurposeAdenoid cystic carcinoma (ACC) represents ~10-15% of salivary neoplasms and almost universally exhibits a lethal clinical course. ACC is also known to occur in the lacrimal gland. ACC is characterized by its heterogeneous morphology and may demonstrate tubular, cribriform, and/or solid architectural patterns. Unfortunately, these histopathological features are not specific to ACC and can be seen in other salivary gland-type neoplasms, introducing a diagnostic dilemma. The discovery of fusion transcripts has revolutionized the diagnosis, surveillance, and treatment of epithelial malignancies. In several anatomic subsites ACC is frequently characterized by a fusion transcript involving genes MYB and NFIB; more specifically, t(6;9)(q22-23;p23-24). This study explores the incidence of MYB rearrangement in cases of lacrimal gland ACC using fluorescent in situ hybridization.Materials and methodsRetrospective clinical and histopathological review of 12 cases of lacrimal gland ACC seen at Mayo Clinic over a 25-year period (1990-2015) was performed. Demographic and clinical data were obtained from medical records. Surgical pathology archival material including H&E slides and immunostains was re-examined. Formalin-fixed paraffin-embedded material was further evaluated using immunohistochemistry when appropriate. Fluorescent in situ hybridization (FISH) using a MYB break-apart probe was applied to all histologically confirmed cases of ACC and benign salivary gland parenchyma.ResultsThe median patient age was 53.6 years (range 12-64) and distributed equally by gender (six male and six female). Rearrangement of MYB was identified using FISH in seven cases (58%). Twenty-five sections of benign salivary gland parenchyma showed no evidence of MYB rearrangement. Primary surgical resection was most common treatment, and 78% of the patient received adjuvant radiation therapy. Median overall survival (OS) was 11 years. Rearrangement of MYB did not affect OS

    The incidence of synchronous bilateral breast carcinomas (BBCs) has increased with a more frequent use of magnetic resonance imaging screening of the contralateral breast in women with newly diagnosed breast cancer. A total of 30% of all BBCs occur synchronously. In the present study, we describe a unique case of synchronous BBC in a 59-year-old previously healthy woman with no known family history of breast or ovarian cancer. At the time of diagnosis the patient had an invasive lobular carcinoma (ILC) in the right breast and an adenoid cystic carcinoma (ACC) in the left breast. To the best of our knowledge, this is the first published case of bilateral, simultaneously occurring ACC and ILC of the breast. Genome-wide genomic profiling of the tumors revealed that they had distinctly different genomic imbalances. The ACC had a 5.7 Mb interstitial 6q deletion with a breakpoint located in the 3'-part of MYB, resulting in loss of the last coding exon of MYB and its 3'-UTR. RT-PCR analysis confirmed that the tumor expressed an ACC-specific MYB-NFIB fusion transcript. In contrast, the ILC had no rearrangements of 6q or MYB-NFIB gene fusion but showed instead gain of 1q21.1-qter, loss of 16q11.2-qter, and 22q12.2-q12.3 as the sole genomic imbalances. Notably, concurrent gains of 1q and losses of 16q are characteristic features of ILC. Collectively, our findings indicate that the ACC and ILC had originated independently of each other and that the MYB-NFIB fusion is a specific biomarker for breast ACC.

    Adenoid cystic carcinoma of the salivary glands has a propensity for perineural invasion, which could favor spread along the major cranial nerves, sometimes to the skull base and through the foramina to the brain parenchyma. This study evaluated the relationship between neural spread and relapse in the skull base. During surgery, we performed multiple biopsies with extemporaneous examination of the major nerves close to the tumor to guide the surgical resection. The percentage of actuarial local control at 5 years for patients with a positive named nerve and skull base infiltration was 12.5%, compared with 90.0% in patients who were named nerve-negative and without infiltration of the skull base (P = .001). Our study shows that local control of disease for patients who are named nerve-positive with skull base infiltration is significantly more complex compared with patients who are named nerve-negative without infiltration of the skull base.

    Hiroyuki Hirakawa

    2017-08-01

    Full Text Available Adenoid cystic carcinoma (ACC is a rare form of adenocarcinoma, which is a broad term describing any cancer that begins in the glandular tissues. It can be found in the head and neck. We report a patient with recurrent ACC arising from the submandibular gland, treated with 100 mg/m2 nedaplatin every 4 weeks. Although our patient’s lactate dehydrogenase levels, which is produced by ACC, showed a rising trend throughout the treatment, the level decreased for approximately 2 weeks immediately after administration of nedaplatin every 4 weeks. Thus, there is a possibility that the agent may be effective. Complications such as anorexia and nausea were observed, but they were tolerated and manageable. Nedaplatin may be considered as a supportive agent during palliative therapy for patients with ACC. More clinical trials regarding nedaplatin are necessary, as this study may indicate that a medical approach works well for ACC.

    Adenoid cystic carcinoma (ACC) is an uncommon salivary gland malignancy characterized by indolent yet relentless growth that exhibits inherent resistance to systemic chemotherapy, surgical salvage and conventional radiotherapy. We used microarray analysis to characterize gene expression changes associated with ACC. Eight ACC patient specimens were compared with normal parotid gland tissue and the ACC3 cell line. Differentially expressed genes were identified (512 total) using supervised analysis methods and functional categories assigned using OntoExpress. Genes associated with morphogenesis, neurogenesis, proliferation and apoptosis characterized ACC tumors. Genes associated with saliva production and immune response characterized normal parotid tissues while the ACC3 cell line expressed genes primarily associated with proliferation, chromosome maintenance and the cell cycle. These results demonstrate that ACC tumors express genes associated with early developmental processes including morphogenesis and neurogenesis implicating oncogenic events that result in dedifferentiation of normal salivary glands.

    Adenoid cystic carcinoma (ACC) is a rare type of cancer that typically originates in the salivary glands. Surgical removal can lead to functional loss and psychological distress. Viscum album extract (VAE) is a herbal remedy with dose-dependent cytotoxic, apoptogenic and immunological effects. In some case reports, tumour regression has been observed following high-dose local applications of VAE. An active 88-year-old man with fast-growing ACC of the hard palate refused surgical removal and received high-dose intratumoural injections of VAE (alone) over a 10-month period. The tumour decreased in size, softened and loosened from its surroundings. A biopsy during the course showed inflammation. The patient remained well and without functional limitations during the therapy and follow-up period (5 months). VAE produced no reported side effects. This aged patient exemplifies a satisfying course of ACC under VAE resulting in good quality of life and partial tumour regression. 2014 BMJ Publishing Group Ltd.

    2007-08-01

    Full Text Available Abstract Background Adenoid Cystic Carcinoma (ACC is a rare tumor entity and comprises about 1% of all malignant tumor of the oral and maxillofacial region. It is slow growing but a highly invasive cancer with a high recurrence rate. Intracranial ACC is even more infrequent and could be primary or secondary occurring either by direct invasion, hematogenous spread, or perineural spread. We report the first case of the 5th and 6th nerve palsy due to cavernous sinus invasion by adenoid cystic carcinoma. Case presentation A 49-year-old African American female presented to the emergency room complaining of severe right-sided headache, photophobia, dizziness and nausea, with diplopia. The patient had a 14 year history migraine headaches, hypertension, and mild intermittent asthma. Physical examination revealed right lateral rectus muscle palsy with esotropia. There was numbness in all three divisions of the right trigeminal nerve. Motor and sensory examination of extremities was normal. An MRI of the brain/brain stem was obtained which showed a large mass in the clivus extending to involve the nasopharynx, pterygoid plate, sphenoid and right cavernous sinuses. Biopsy showed an ACC tumor with a cribriform pattern of the minor salivary glands. The patient underwent total gross surgical resection and radiation therapy. Conclusion This is a case of ACC of the minor salivary glands with intracranial invasion. The patient had long history of headaches which changed in character during the past year, and symptoms of acute 5th and 6th cranial nerve involvement. Our unique case demonstrates direct invasion of cavernous sinus and could explain the 5th and 6th cranial nerve involvement as histopathology revealed no perineural invasion.

    Adenoid cystic carcinoma (ACC) is a relatively rare slow-growing and often-aggressive epithelial-myoepithelial neoplasm that arises in multiple organs including the skin. The t(6;9) (q22-23;p23-24) translocation, resulting in a MYB-NFIB gene fusion has been found in ACCs from the salivary glands and other organs. Recently, MYB aberrations occurring in a subset (40%) of primary cutaneous ACC (PCACC) examples was described. Herein, we report three additional cases of PCACC harboring MYB aberrations. The tumors presented in three males aged 43, 81 and 55 years old and affected the extremities in the first two patients and the scalp in the third one. None of the patients had history of prior or concurrent ACC elsewhere. Lesions exhibited the classic ACC morphology of nests of basaloid cells arranged in cribriform and adenoid patterns. Sentinel lymph node biopsy was performed in two cases with one case showing lymph node positivity. Fluorescence in situ hybridization with break-apart probes for MYB and NFIB loci revealed that two cases showed MYB rearrangements while one case showed loss of one MYB signal. None of the cases showed NFIB rearrangements. We contribute with three additional cases of PCACC exhibiting MYB aberrations, the apparent driving genetic abnormality in these tumors. © 2016 John Wiley & Sons A/S.

    We compared 4 breast cylindromas with 50 dermal cylindromas and 8 adenoid cystic breast carcinomas. Except for a modest increase in the number of eccrine ducts and reactive Langerhans cells in dermal cylindromas, breast and dermal cylindromas showed identical histologic and immunohistochemical features. Both were characterized by epithelial islands containing central basaloid cells and peripheral myoepithelial cells surrounded by a thickened, continuous, periodic acid-Schiff-positive basement membrane that was immunoreactive for collagen IV. Clusters of sebaceous cells and a few eccrine ducts are described in breast cylindromas. Cytokeratin 7 labeled predominantly the central basaloid cells, and smooth muscle actin stained peripheral myoepithelial cells in breast and dermal cylindromas. Eccrine ducts were highlighted by epithelial membrane antigen and carcinoembryonic antigen. S-100 protein and CD1a showed a variable number of dendritic Langerhans cells. Cylindromas of the breast and skin did not express cytokeratin 20, gross cystic disease fluid protein 15, or estrogen or progesterone receptor. Breast cylindroma might be confused with the solid variant of adenoid cystic carcinoma, especially in needle core biopsy specimens, because they share nodular and trabecular patterns, basaloid cells, myoepithelial cells, eccrine ducts, and hyaline globules of basement membrane material. However, adenoid cystic carcinoma displays an infiltrative growth pattern, cytologic atypia, and mitotic figures and lacks the continuous, thickened basement membrane.

    Cancer/testis antigens (CTAs) are detected in cancer cells but not in healthy normal tissues, with the exception of gametogenic tissues. CTAs are highly immunogenic proteins, and thus represent ideal targets for cytotoxic T-lymphocyte-mediated specific immune therapy. The aim of this study was to screen CTA expression in various types of salivary gland carcinoma and to clarify clinicopathological significance of MAGE-A and NY-ESO-1 expression in adenoid cystic carcinomas (AdCCs) of the salivary gland, which is one of the most common salivary gland carcinomas, and usually has a fatal outcome. We used immunohistochemistry to examine the expression of four CTAs (MAGE-A, NY-ESO-1, CT7, and GAGE7) in various types of salivary gland carcinoma (n = 95). When carcinoma cases were divided into low-grade and intermediate/high-grade types, NY-ESO-1 and CT7 were expressed more frequently in intermediate/high-grade carcinomas. We then focused on MAGE-A and NY-ESO-1 expression in a large cohort of adenoid cystic carcinomas (AdCCs) (n = 46). MAGE-A and NY-ESO-1 were frequently expressed in AdCC; specifically, MAGE-A was expressed in >60% of the AdCC cases. MAGE-A expression and tumour site (minor salivary gland) were identified as independent risk factors for locoregional tumour recurrence. These findings suggest that CTAs may be expressed in a variety of salivary gland carcinomas, especially in those with higher histological grades. In addition, MAGE-A, which is frequently expressed in AdCC cases, may be a useful prognostic factor for poorer locoregional recurrence-free survival. © 2017 John Wiley & Sons Ltd.

    Adenoid cystic carcinoma (ACC) is a rare epithelial malignancy arising from secretory glands, particularly the salivary glands. It tends to invade nerves and has a high potential for distant hematogenous metastasis, especially to the lungs, bone, liver and brain. The breast and hypophysis are not common sites of ACC metastatic disease. Herein, we report a case of ACC of the head and neck region with two unusual sites of metastases, the hypophysis and breast.

    This study was to investigate clinicopathologic characteristics and prognostic factors in adenoid cystic carcinoma of head and neck minor salivary glands. We conducted a retrospective review of 130 patients with adenoid cystic carcinoma of head and neck minor salivary glands that were evaluated between 2000 and 2013 in Beijng Tongren Hospital. Five-year overall survival and disease-free survival rates were 80.8% and 55.6%. Local recurrence rate was 40%, regional recurrence 3.8%, and distant metastasis was 28.5%. On univariate analysis, solid histological subtype, perineural invasion, positive surgical margins and advanced stages were found to be poor prognostic indicators. On multivariate analysis, solid histological subtype and positive surgical margins were significant prognostic factors of worse overall survival. Solid histological subtype and positive surgical margins were the most important predictors of poor outcome in adenoid cystic carcinoma of minor salivary glands. Surgery with postoperative radiation were recommended treatment and offered durable local control. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Adenoid cystic carcinoma (ACC is an uncommon malignancy of the salivary glands that is characterized by local recurrence and distant metastasis due to its resistance to conventional therapy. Platinum-based therapies have been extensively explored as a treatment for ACC, but they show little effectiveness. Studies have shown that a specific group of tumor cells, harboring characteristics of cancer stem cells (CSCs, are involved in chemoresistance of myeloid leukemias, breast, colorectal and pancreatic carcinomas. Therapeutic strategies that target CSCs improve the survival of patients by decreasing the rates of tumor relapse, and epigenetic drugs, such as histone deacetylase inhibitors (HDACi, have shown promising results in targeting CSCs. In this study, we investigated the effect of the HDACi Suberoylanilide hydroxamic acid (Vorinostat, and cisplatin, alone or in combination, on CSCs and non-CSCs from ACC. We used CSCs as a biological marker for tumor resistance to therapy in patient-derived xenograft (PDX samples and ACC primary cells. We found that cisplatin reduced tumor viability, but enriched the population of CSCs. Systemic administration of Vorinostat reduced the number of detectable CSCs in vivo and in vitro, and a low dose of Vorinostat decreased tumor cell viability. However, the combination of Vorinostat and cisplatin was extremely effective in depleting CSCs and reducing tumor viability in all ACC primary cells by activating cellular senescence. These observations suggest that HDACi and intercalating agents act more efficiently in combination to destroy tumor cells and their stem cells.

    The purpose of this study was to explore the factors associated with the recurrence of adenoid cystic carcinomas (ACCs). We examined the recurrence values of clinicopathological variables and GLUT-1, p-Akt and PI3K expression in 42 patients with ACC. Of the 42 patients, 17 developed recurrence following initial surgery. The positive rates of GLUT-1, PI3K and p-Akt protein expression in ACC were 38.1, 38.1 and 50.0%, respectively. The expression of GLUT-1, p-Akt or PI3K protein in ACC was higher than that in inflammatory lesions or benign tumors. Our study demonstrated that T stage, a positive resection margin, perineural invasion, surgery without postoperative radiotherapy and the expression of GLUT-1, PI3K and p-Akt were factors predictive of recurrence by univariate analyses. In multivariate analyses, perineural invasion, a positive resection margin and p-Akt were significant predictors of recurrence. Initial surgery is very significant in the recurrence of ACC. Overexpression of GLUT-1, PI3K and p-Akt may also play a role in its development and recurrence. PMID:23226799

    Full Text Available Abstract Background Thymidylate synthase (TS is an important target for chemotherapeutic treatment of cancer and high expression of TS has been associated with poor prognosis or refractory disease in several cancers including colorectal and head and neck cancer. Although TS is known to regulate cell cycles and transcription factors, its potency as a therapeutic target has not been fully explored in adenoid cystic carcinoma (ACC. Methods An ACC cell line (ACC3 was transfected with siRNA targeting the TS gene and inhibition of cell growth and induction of apoptosis-associated molecules were evaluated in vitro. In addition, the in vivo effect of TS siRNA on tumor progression was assessed using a xenograft model. Results Our results demonstrated that ACC3 cells showed significantly higher TS expression than non-cancer cell lines and the induction of TS siRNA led to inhibition of cell proliferation. The effect was associated with an increase in p53, p21, and active caspase-3 and S-phase accumulation. We also found up-regulation of spermidine/spermine N1-acetyltransferase (SSAT, a polyamine metabolic enzyme. Furthermore, treatment with TS siRNA delivered by atelocollagen showed a significant cytostatic effect through the induction of apoptosis in a xenograft model. Conclusion TS may be an important therapeutic target and siRNA targeting TS may be of potential therapeutic value in ACC.

    Aims The majority of adenoid cystic carcinomas (AdCCs), regardless of anatomical site, harbour the MYB–NFIB fusion gene. The aim of this study was to characterize the repertoire of somatic genetic events affecting known cancer genes in AdCCs. Methods and results DNA was extracted from 13 microdissected breast AdCCs, and subjected to a mutation survey using the Sequenom OncoCarta Panel v1.0. Genes found to be mutated in any of the breast AdCCs and genes related to the same canonical molecular pathways, as well as KIT, a proto-oncogene whose protein product is expressed in AdCCs, were sequenced in an additional 68 AdCCs from various anatomical sites by Sanger sequencing. Using the Sequenom MassARRAY platform and Sanger sequencing, mutations in BRAF and HRAS were identified in three and one cases, respectively (breast, and head and neck). KIT, which has previously been reported to be mutated in AdCCs, was also investigated, but no mutations were identified. Conclusions Our results demonstrate that mutations in genes pertaining to the canonical RAS pathway are found in a minority of AdCCs, and that activating KIT mutations are either absent or remarkably rare in these cancers, and unlikely to constitute a driver and therapeutic target for patients with AdCC.

    Reversion-inducing cysteine-rich protein with kazal motifs (RECK), a novel tumor suppressor gene that negatively regulates matrix metalloproteinases (MMPs), is expressed in various normal human tissues but downregulated in several types of human tumors. The molecular mechanism for this downregulation and its biological significance in salivary adenoid cystic carcinoma (SACC) are unclear. In the present study, we investigated the effects of a DNA methyltransferase (DNMT) inhibitor, 5-aza-2′deoxycytidine (5-aza-dC), on the methylation status of the RECK gene and tumor invasion in SACC cell lines. Methylation-specific PCR (MSP), Western blot analysis, and quantitative real-time PCR were used to investigate the methylation status of the RECK gene and expression of RECK mRNA and protein in SACC cell lines. The invasive ability of SACC cells was examined by the Transwell migration assay. Promoter methylation was only found in the ACC-M cell line. Treatment of ACC-M cells with 5-aza-dC partially reversed the hypermethylation status of the RECK gene and significantly enhanced the expression of mRNA and protein, and 5-aza-dC significantly suppressed ACC-M cell invasive ability. Our findings showed that 5-aza-dC inhibited cancer cell invasion through the reversal of RECK gene hypermethylation, which might be a promising chemotherapy approach in SACC treatment.

    Adenoid cystic carcinoma (ACC) of the breast is a rare type of breast cancer, which presents inconsistencies in the optimal management strategy. A retrospective review of prospectively collected data, spanning the last 20 years, was performed using the cancer registry database at our institution. Six patients were diagnosed with ACC of the breast, out of 5,813 total patients diagnosed with breast cancer (0.1%). Our identified patients had a median age of 66, all with the early stage cancer (Stage I/II). The average size of the breast lesion was 1.62 cm, and nodal status was negative for all cases. All patients had resection as primary therapy (partial or total mastectomy), with one patient also undergoing external beam radiation and tamoxifen hormonal therapy. Median follow-up was 85 months, with all patients being disease-free at last follow-up. ACC of the breast has an indolent course, despite triple negative status. Our study suggests that radiation may not be warranted and confirms the rarity of axillary node metastases, indicating that sentinel node excision may also not be necessary. Ultimately, the hope is that our findings along with the reviewed literature will aid in determining the most appropriate options for management of ACC of the breast.

    Naltrexone (ReVia®) is a long-acting oral pure opiate antagonist which is approved for the treatment of alcohol addiction as a 50mg per day tablet. The mechanism of action is complete opiate blockade, which removes the pleasure sensation derived from drinking alcohol (created by endorphins). Low Dose Naltrexone ("LDN") in the range of 3-4.5 mg per day has been shown to have the opposite effect - brief opiate receptor blockade with resulting upregulation of endogenous opiate production. Through the work of Bihari and Zagon, it has been determined that the level of the endogenous opiate methionine-enkephalin is increased by LDN. Met-enkephalin is involved in regulating cell proliferation and can inhibit cancer cell growth in multiple cell lines. Increased met-enkepahlin levels created by LDN thus have the potential to inhibit cancer growth in humans. Phase II human trials of met-enkephalin, case reports published by Berkson and Rubin, and the clinical experience of Bihari confirmed the potential role of LDN in treating pancreatic and other cancers. However, large scale trials are lacking and are unlikely to be funded given the current non-proprietary status of naltrexone. A case report is presented of successful treatment of adenoid cystic carcinoma as further evidence of LDN's potential as a unique non-toxic cancer therapy.

    Adenoid cystic carcinoma (AdCC) of the head and neck is an uncommon malignant epithelial tumour of the secretory glands. Many patients develop slowly growing local recurrence and/or distant metastasis, for which treatment options are limited. A retrospective analysis of 9 AdCC patients was conducted to analyse the visualization of AdCC on PSMA PET/CT and to investigate the expression of PSMA on primary, recurrent and metastatic AdCC tumour tissue using immunohistochemistry. Local recurrence occurred in six patients and eight developed distant metastasis. All PET/CTs depicted PSMA-ligand uptake. Four PSMA PET/CTs showed suspected residual disease, eight scans depicted uptake in areas suspected of distant metastasis. Median Maximum Standardized Uptake Value (SUV{sub max}) in local recurrent and distant metastatic AdCC was 2.52 (IQR 2.41-5.95) and 4.01 (IQR 2.66-8.71), respectively. All primary tumours showed PSMA expression on immunohistochemistry (5-90% expression), as well as all available specimens of local recurrence and distant metastases. PSMA PET/CT is able to detect and visualize local recurrent and distant metastatic AdCC. PSMA-specific targeting is supported by PSMA expression on immunohistochemistry. (orig.)

    Full Text Available Abstract Objectives This study consisted of two parts. One part was to analyze the survival rates of adenoid cystic carcinoma (ACC in Chinese and explain the difference between our data and the literature. The other was to analyze the relationship between the expression of CD117 and the histological grade and the prognosis. Methods A retrospective study of 80 ACC patients was performed. Clinical data were collected, and p63, CD117 were detected by immunohistochemical staining. Results Eighty patients received follow-ups 3 to 216 months after initial diagnosis. ACC occurred in the lacrimal gland (26.3%, n = 21, nasal cavity and parasinus (33.8%, n = 27 and other sites (40.0%, n = 33. The 5-year and 10-year survival rates were 66.41% and 10.16%, respectively. Over expression of CD117 was detected in p63-negative cells in 94.3% of cases and in p63-positive cells in 45.8%. The expression of CD117 in p63-positive cells was significantly associated with the histological grade (P Conclusions ACC had a good 5-year survival but poor 10-year survival in Chinese, which differed from the occidental data. More p63+/CD117+ cells were associated with a higher histological grade and poorer outcome.

    Background and purpose: This retrospective study was to evaluate the local control and survival of {sup 125}I brachytherapy for recurrent and/or locally advanced adenoid cystic carcinoma (ACC) of the oral and maxillofacial region. Patients and methods: A total of 38 patients with recurrent and/or locally advanced ACC of the oral and maxillofacial region received {sup 125}I brachytherapy alone from 2001-2010. Twenty-nine were recurrent cases following previous surgery and radiation therapy. The other 9 cases involved primary tumors. Overall, 12 tumors were located in the major salivary glands, 12 in the minor salivary glands, and 14 in the paranasal region, the nasal cavity or the skull base. The prescribed dose was 100-160 Gy. Results: Patients were followed for 12-122 months (median 51 months). The 2-, 5-, and 10-year local tumor control rates were 86.3, 59, and 31.5 %, respectively. The 2-, 5-, and 10-year overall survival rates were 92.1, 65 and 34.1 %, respectively. Tumors > 6 cm had significantly lower local control and survival rates. No severe complications were observed during follow-up. Conclusion: {sup 125}I brachytherapy is a feasible and effective modality for the treatment of locally advanced unresectable or recurrent ACC.

    Breast adenoid cystic carcinoma (ACC) is a primary breast carcinoma that, like salivary gland ACC, displays the t(6;9) translocation resulting in the MYB-NFIB gene fusion and immunopositivity for MYB by immunohistochemistry (IHC). However, it is not well established whether MYB immunoreactivity or rearrangement can be used to support a diagnosis of ACC in a malignant basaloid or benign cribriform breast lesion. Whole sections of primary breast ACC (n=11), collagenous spherulosis (CS; n=7), and microglandular adenosis (MGA; n=5) and tissue microarrays containing 16 basal-like, triple-negative breast carcinomas (TNBC) were labeled for MYB by IHC and underwent MYB fluorescence in situ hybridization using a break-apart probe. Strong, diffuse nuclear MYB labeling was seen in 100% ACC compared with no cases of basal-like TNBC, CS, or MGA (P=0.0001). Any degree of nuclear MYB labeling was seen in 100% ACC compared with 54% of all other cases (P=0.007), with any labeling seen in 71% CS, 63% basal-like TNBC, and 0% MGA. MYB rearrangement was detected in 89% (8/9) of evaluable ACC compared with 4% (1/26) of all other evaluable cases (P=0.0001), with a rearrangement detected in 1 (7%; n=1/15) evaluable basal-like TNBC. Strong, diffuse nuclear labeling for MYB is more sensitive than MYB fluorescence in situ hybridization for breast ACC and can be used to support a diagnosis of ACC in a cribriform or basaloid lesion in the breast. However, weak and focal labeling should be interpreted with caution as it can be seen in other benign cribriform and malignant basaloid lesions.

  18. Efficacy of sorafenib, a multi-tyrosine kinase inhibitor, in an adenoid cystic carcinoma metastatic to the lung: case report and review of literature

    Full Text Available Abstract Introduction Treatment for squamous cell carcinoma of the head and neck has significantly improved with the addition of cetuximab, a monoclonal antibody against the epidermal growth factor receptor, to conventional cytotoxic agents. The most significant aspect of this treatment approach is the proof that head and neck cancers are suitable for targeted therapies as has been shown in other malignancies. Unfortunately, there are other rare histologic types of head and neck cancer such as adenocarcinoma and adenoid cystic carcinoma. The latter has traditionally been considered to be chemotherapy resistant and surgical resection with or without adjuvant radiation therapy has been the rule as far as treatment is concerned. The course of adenoid cystic carcinoma ranges from indolent to aggressive; however, most patients succumb to the disease as a result of distant metastases. This clinical scenario poses a challenge to oncologists. Several conventional chemotherapy regimens and novel targeted agents have been tried in this rare histologic subtype without success. Case presentation In this case report, we present a 59-year-old Caucasian female with refractory adenoid cystic carcinoma of the maxilla metastatic to the lung that responded to sorafenib, a novel multi-tyrosine kinase inhibitor, which targets angiogenesis, Raf kinase pathway, platelet-derived growth factor Ret, and c-Kit. Conclusion This case illustrates the possibility that this chemoresistant tumor may need the inhibition or blocking of several oncogenic pathways. Certainly, it is imperative that more studies are done in this special population trying to identify tumorigenesis mechanisms that may be upregulated in this malignancy and could be potential targets for therapeutic development.

    2006-08-01

    Full Text Available Abstract Background Adenoid basal carcinoma of the cervix is a rare condition mostly occurring among postmenopausal women. Although it can be confused with adenoid cystic carcinoma of the cervix, adenoid basal carcinoma has several clinicopathologic features that will allow distinction from adenoid cystic carcinoma. Case presentation This is the case of a twenty-year old African-American female who initially presented with a high-grade squamous intraepithelial lesion on Pap smear, with a subsequent cervical LEEP specimen revealing adenoid basal carcinoma. The lesion showed the characteristic histologic features of adenoid basal carcinoma and was positive for the immunohistochemical marker EMA and negative for collagen IV, further defining the tumor while helping to rule out the possibility of adenoid cystic carcinoma. As far as the authors are aware, this is the youngest reported case of adenoid basal carcinoma to date. Conclusion This case shows that adenoid basal carcinoma can deviate markedly from its typical postmenopausal demographics to affect women as young as 20 years of age. In addition, adenoid basal carcinoma has several identifiable features that will differentiate it from adenoid cystic carcinoma including histologic and cellular morphologies, as well as immunohistochemistry. Treatment for most patients involves hysterectomy, LEEP, or a conization procedure which provides a favorable prognosis because of this lesion's low potential for recurrence and metastasis.

Although it can be confused with adenoid cystic carcinoma of the cervix, adenoid basal carcinoma has several clinicopathologic features that will allow distinction from adenoid cystic carcinoma. Case presentation This is the case of a twenty-year old African-American female who initially presented with a high-grade squamous intraepithelial lesion on Pap smear, with a subsequent cervical LEEP specimen revealing adenoid basal carcinoma. The lesion showed the characteristic histologic features of adenoid basal carcinoma and was positive for the immunohistochemical marker EMA and negative for collagen IV, further defining the tumor while helping to rule out the possibility of adenoid cystic carcinoma. As far as the authors are aware, this is the youngest reported case of adenoid basal carcinoma to date. Conclusion This case shows that adenoid basal carcinoma can deviate markedly from its typical postmenopausal demographics to affect women as young as 20 years of age. In addition, adenoid basal carcinoma has several identifiable features that will differentiate it from adenoid cystic carcinoma including histologic and cellular morphologies, as well as immunohistochemistry. Treatment for most patients involves hysterectomy, LEEP, or a conization procedure which provides a favorable prognosis because of this lesion's low potential for recurrence and metastasis.

    The purpose of this study was to establish general guidelines in the management of the N0 neck of oral cavity and oropharyngeal adenoid cystic carcinoma (AdCC) in order to improve the survival of these patients and/or reduce the risk of neck recurrences. The incidence of cervical node metastasis at diagnosis of head and neck AdCC is variable, and ranges between 3% and 16%. Metastasis to the cervical lymph nodes of intraoral and oropharyngeal AdCC varies from 2% to 43%, with the lower rates pertaining to palatal AdCC and the higher rates to base of the tongue. Neck node recurrence may happen after treatment in 0–14% of AdCC, is highly dependent on the extent of the treatment and is very rare in patients who have been treated with therapeutic or elective neck dissections, or elective neck irradiation. Lymph node involvement with or without extracapsular extension in AdCC has been shown in most reports to be independently associated with decreased overall and cause-specific survival, probably because lymph node involvement is a risk factor for subsequent distant metastasis. The overall rate of occult neck metastasis in patients with head and neck AdCC ranges from 15% to 44%, but occult neck metastasis from oral cavity and/or oropharynx seems to occur more frequently than from other locations such as the sinonasal tract and major salivary glands. Nevertheless, the benefit of elective neck dissection (END) in AdCC is not comparable to that of squamous cell carcinoma, because the main cause of failure is not related to neck or local recurrence, but rather, to distant failure. Therefore, END should be considered in patients with a cN0 neck with AdCC in some high risk oral and oropharyngeal locations when postoperative RT is not planned, or the rare AdCC-high grade transformation.

    Full Text Available Human adenoid cystic carcinoma (ACC is characterized by diffused invasion of the tumor into adjacent organs and early distant metastasis. Anoikis resistance and epithelial mesenchymal transition (EMT are considered prerequisites for cancer cells to metastasize. Exploring the relationship between these processes and their underlying mechanism of action is a promising way to better understand ACC tumors. We initially established anoikis-resistant sublines of ACC cells; the variant cells revealed a mesenchymal phenotype through Slug-mediated EMT-like transformation and displayed enhanced metastatic potential both in vitro and in vivo. Suppression of EMT by knockdown of Slug significantly impaired anoikis resistance, migration, and invasion of the variant cells. With overexpression of Slug and Twist, we determined that induction of EMT in normal ACC cells could prevent anoikis, albeit partially. These findings strongly suggest that EMT is indispensable in anoikis resistance, at least in ACC cells. Furthermore, we found that the EGFR/PI3K/Akt pathway acts as the common regulator for EMT-like transformation and anoikis resistance, as confirmed by their specific inhibitors. Gefitinib and LY294003 restored the sensibilities of anoikis-resistant cells to anoikis and simultaneously impaired their metastatic potential. In addition, the results from our in vivo model of metastasis suggest that pretreatment with gefitinib promotes mouse survival by alleviating pulmonary metastasis. Most importantly, immunohistochemistry of human ACC specimens showed a correlation between the overexpression of Slug and EGFR staining. This study has demonstrated that Slug-mediated EMT-like transformation is required by human ACC cells to achieve anoikis resistance and their metastatic potential. Targeting the EGFR/PI3K/Akt pathway holds potential as a preventive strategy against distant metastasis of ACC.

New histological diagnosis was made on freshly prepared H&E sections followed by application and analysis of immunostains.The mean age of the patients was 44 ± 15 (mean SD (range; 17-86 years. There were 26 male and 24 female patients with a male to female ratio of 1.08:1. Fourteen cases of PA, 14 cases of AdCC and 6 cases of PLGA were positive for CD117. In case of GFAP, only 9 cases of AdCC and 3 cases of PLGA were positive; however, 16 cases of PA were also positive. Twelve cases of AdCC and 7 cases of PA were positive for SMA and half of the PLGA cases were also reactive. Nonetheless, the least expression was seen in case of CD 43, where only five cases of AdCC were positive. Six cases of PA and three cases of PLGA were also positive.Our results suggest that the use of GFAP, SMA, CD 117 and CD 43 as an adjunct to histological examination is not helpful in differentiating PA, AdCC and PLGA from one another.

    Adenoid cystic carcinoma (ACC) of the breast is a rare breast cancer variant and optimal management is unclear. A review of this unusual tumour was performed at our Institution, to assess the role of breast conservation in the management of this disease. A review of all cases of ACC of breast (1960-2000) treated at Princess Margaret Hospital (PMH) was undertaken. Information was collected on age at diagnosis, presenting features, tumour size and treatment modalities. Treatment outcomes were evaluated. Eighteen female and one male patient were identified. Median age at diagnosis was 58 years (range 35-76 years). Four patients had lymph-node positive disease at presentation; the single male patient presented with metastatic disease. Surgery was either a lumpectomy (10 cases) or a simple, radical or modified radical mastectomy (9 patients). Nine of 19 patients received adjuvant radiotherapy (RT). The median follow-up time was 14 years; the recurrence rate at 10 years was 31% (95% CI 7-54%) with a range in time of recurrence from 2.3 to 11.9 years. Seven recurrences were identified (4 local, 1 regional, 2 metastatic). Two of these patients developed metastatic spread and died. Six of the 19 cases went on to develop second malignancies of whom four died. Among the 18 female patients, the 10-year overall (OS), cause-specific (CSS), and relapse free survival (RFS) rates were 75, 100, and 46% respectively. ACC of the breast has a relatively prolonged natural history, and responds well to conservative management at presentation, with good outcome, even following local recurrence.

    Full Text Available Cancer stem cells (CSC are considered the major cause of aggressive tumor behavior, recurrence, metastases, and resistance to radiation, making them an attractive therapeutic target. However, isolation of CSC from tumor tissue and their characterization are challenging due to uncertainty about their molecular markers and conditions for their propagation. Adenoid cystic carcinoma (ACC, which arises predominantly in the salivary glands, is a slow-growing but relentless tumor that frequently invades nerves and metastasizes. New effective treatment approaches for ACC have not emerged over the last 40 years. Previously, based on a highly conserved SOX10 gene signature that we identified in the majority of ACC tumors, we suggested the existence in ACC of SOX10+ cells with neural stem properties and corroborated this hypothesis via isolation from ACC tissue a novel population of CSC, termed ACC-CSC. These cells activated NOTCH1 signaling and co-expressed SOX10 and other ACC-intrinsic neural crest stem cell markers with CD133, a CSC cell surface marker, suggesting that ACC is driven by a previously uncharacterized population of SOX10+/CD133+ cells with neural stem cell properties. Here, we authenticated ACC identity of our primary cultures by demonstrating that most of them harbor MYB-NFIB fusions, which are found in 86% of ACC. We demonstrated using CyTOF, a novel mass cytometry technology, that these cells express high β-catenin and STAT3 levels and are marked by CD24 and CD44. Finally, to streamline development of ACC cell lines, we developed RT-PCR tests for distinguishing mouse and human cells and used immunomagnetic cell sorting to eliminate mouse cells from long-term cell cultures. Overall, this study describes a new population of CSC that activates signaling pathways associated with poor prognosis, validates their ACC identity, and optimizes approaches that can be used for purification of ACC-CSC and generation of cell lines.

    Breast adenoid cystic carcinoma (AdCC), a rare type of triple-negative breast cancer (TNBC), has been shown to be driven by MYB pathway activation, most often underpinned by the MYB-NFIB fusion gene. Alternative genetic mechanisms, such as MYBL1 rearrangements, have been reported in MYB-NFIB-negative salivary gland AdCCs. Here we report on the molecular characterization by massively parallel sequencing of four breast AdCCs lacking the MYB-NFIB fusion gene. In two cases, we identified MYBL1 rearrangements (MYBL1-ACTN1 and MYBL1-NFIB), which were associated with MYBL1 overexpression. A third AdCC harbored a high-level MYB gene amplification, which resulted in MYB overexpression at the mRNA and protein levels. RNA-sequencing and whole-genome sequencing revealed no definite alternative driver in the fourth AdCC studied, despite high levels of MYB expression and the activation of pathways similar to those activated in MYB-NFIB-positive AdCCs. In this case, a deletion encompassing the last intron and part of exon 15 of MYB, including the binding site of ERG-1, a transcription factor that may down-regulate MYB, and the exon 15 splice site, was detected. In conclusion, we demonstrate that MYBL1 rearrangements and MYB amplification likely constitute alternative genetic drivers of breast AdCCs, functioning through MYBL1 or MYB overexpression. These observations emphasize that breast AdCCs likely constitute a convergent phenotype, whereby activation of MYB/MYBL1 and their downstream targets can be driven by the MYB-NFIB fusion gene, MYBL1 rearrangements, MYB amplification or other yet to be identified mechanisms.

    Adenoid cystic carcinoma (ACC) is one of the common malignant tumors in salivary glands, and the clinical prognosis is poor with frequent distant metastasis which may lead to death. Expression of the MYB-NFIB chimeric gene in ACC has been reported recently. MYB is an oncogene with transcription regulating functions, and NFIB encodes nuclear transcription factor although detailed functions are unknown. This study investigated whether MYB-NFIB chimeric gene expression affects tumor angiogenesis and proliferation in salivary gland ACC. In 26 salivary gland ACC cases, MYB-NFIB chimeric gene expression was analyzed by RT-PCR and direct sequencing. Immunohistochemical studies for CD31, vascular endothelial growth factor (VEGF) and Ki-67 were performed. Tumor angiogenesis was evaluated by blood vessel (CD31-positive) density and tumor proliferation by Ki-67 labeling index, and the relationship with MYB-NFIB chimeric gene expression was analyzed. MYB-NFIB chimeric gene expression was detected in nine of 26 ACC cases. Blood vessel density was significantly higher in chimeric gene-expressing cases compared to non-expressing cases. VEGF score tended to be higher in chimeric gene-expressing cases than in non-expressing cases, while Ki-67 labeling index was not significantly different. The number of chimeric gene-expressing cases increased with age, peaking in the sixties age group and declining thereafter, while the number of non-expressing cases increased with age continuously. In ACC, blood vessel density was significantly higher in MYB-NFIB chimeric gene-expressing cases compared to non-expressing cases, which may be due to higher VEGF production capability. MYB-NFIB chimeric gene expression may also be related to the onset age of ACC.

    Epithelial-mesenchymal transition (EMT) is a complicated process that has been implicated in cancer progression and metastasis as well as the formation of many tissues and organs. BTB/POZ domain-containing protein 7 (BTBD7) is reported to regulate transcriptional factors and involved in the process of invasion and metastasis of some malignant tumors. Additionally, our preliminary studies have confirmed that BTBD7 expression was significantly correlated with Slug expression and poor prognosis of primary salivary adenoid cystic carcinoma (SACC). On this basis, this study further investigated function of BTBD7 in the invasion and metastasis of SACC in vitro, which may be a possible target of gene therapy in the future. The expression of BTBD7 and Slug were both examined in SACC-LM and SACC-83 cell lines by immunofluorescence staining. High invasive SACC-LM cells were transfected with BTBD7 siRNA and the expression levels of BTBD7 and Slug were detected in both gene and protein levels by qRT-PCR and western blot analysis. Assays were performed to survey cell migration, invasion and proliferation capabilities with BTBD7 silencing. BTBD7 and Slug proteins were detected in SACC-LM and SACC-83 cell lines. BTBD7 silencing down-regulated the expression of Slug and MMP9 meanwhile up-regulated the expression of E-cadherin in SACC-LM cells, the migration and invasion abilities of cells were obviously suppressed but with no influence on cell proliferation. BTBD7 silencing inhibited EMT through regulation of Slug expression in SACC-LM cells and might act as a potential molecular target for gene therapy of SACC.

    Full Text Available Background : Mexico′s National Institute of Respiratory Diseases (NIRD is a third-level national reference center. Primary adenoid cystic carcinoma (PACC is an uncommon neoplastic disorder; hence improvements in the description of this disease are needed. Materials and Methods: This is a retrospective clinical study based on all consecutive patients with pathological diagnoses of PACC seen at the NIRD between January 1, 2000 and December 31, 2009. Results: We identified 9 cases of PACC (67% female out of a total of 2,634 patients with lung cancer seen during the period analyzed. The mean age of those 9 patients was 41 years (IQR 36-57, and the frequency of PACC at our center was 0.3%. It is important to note that 67% of those patients had a history of smoking and that 6 of the 9 had the antecedent of previous exposure to biomass fuel smoke. Baseline arterial blood gas analyses revealed a median of 61 mmHg for pO 2 and 28.5 mmHg for pCO 2 . Median FVC was 78%, while FEV 1 was 77% with an FEV 1 /FVC ratio of 78. Death occurred in 56% of cases, and the median survival time was 17 months (IQR 6-26 after the initial diagnosis. Conclusions: The frequency of tracheobronchial PACC among patients with lung cancer was similar to that previously reported (0.3%. According to our results, lung function has no specific phenotype in this disease; however, some abnormalities could be related to potential risk factors such as tobacco use and exposure to biomass fuel smoke.

    Forty eight patients with adenoid cystic carcinoma(ACC) in the head and beck treated between 1979 and 1990 were reviewed according to treatment modalities and clinical courses. The common site of origin was minor salivary gland (69%), mostly had palate and maxillary sinus. 11 patients received radiation therapy(RT) alone and 37 patients received combined surgery and radiation therapy. The follow-up period of the survivors ranged from 4 to 118 months (median 49.5 months). The 5 year local control rate was 69.3%, 67.3% and 83.9% in RT alone, conservative operation(OP)+RT and radical OP+RT group, respectively(p>0.05). The control of local disease was best achieved with radical OP+RT. In postoperative RT, high dose ({>=}60 Gy) and generous field size (>64cm{sup 2}) yielded a better local control rate. Actuarial overall survival rate was 79.0%, at 5 years and 19.2% at 10 years. Distant metastases (DM) developed in 40% of patients, mostly in the lung. Disease-free(NED) survival rate was 45.8%, at 5 years and significant differences did not exist according to primary sites and treatment options. Survival rate after the onset of DM was 19.5% at 5 years. Occurrence of DM tends to lower survival significantly. In an effort to find the role of RT in the treatment of ACC, our data suggest that a well-planned postoperative RT employing a high dose and generous field size can produce high local control rate and remaining urgent problem of distant metastasis demands more effective chemotherapy for the purpose of improving survival of ACC patients.

    The aim of this study was to investigate the clinicopathological characteristic of adenoid cystic carcinoma (ACC). The clininopathological features, along with relapse free survival(RFS) and overall survival(OS) of 36 patients with ACC were retrospectively investigated and compared with those of 108 grade 1 invasive ductal carcinoma not-otherwise-specified (G1-IDC-NOS) patients. Most cases of ACC were ER, PR and HER-2 negative which was classified as triple-negative subtype. Five cases were concomitant with other pathological types of cancer. Axillary lymph node dissection(ALND) was performed in 31 patients and 2 of them with lymph nodes metastasis. Two patients died of lung metastases at 46 and 116 months after the surgery respectively. Compared with G1-IDC-NOS, ACC showed lower Ki-67 index, less lymph nodes metastasis, lower P53 expression, and higher proportion in location of upper outer quadrant of breast. There was no difference of OS and RFS between ACC and G1-IDC-NOS. ACC of the breast was a rare disease with a good prognosis although most of them were classified as triple-negative subtype. And the value of axillary node dissection and adjuvant therapy needs to be further investigated. Copyright © 2017 Elsevier GmbH. All rights reserved.

    Epithelial-myoepithelial carcinoma (EMC) is a rare salivary gland malignancy associated with an overall good prognosis. Fine-needle aspiration (FNA) typically shows a dual population of myoepithelial and ductal cells. Rarely, acellular matrix globules are present, raising a differential diagnosis of adenoid cystic carcinoma (AdCC), a more aggressive salivary gland malignancy associated with a poor long-term prognosis. We report an FNA case of EMC containing a predominant pattern of AdCC-like spherical globules. We compare features of an unusual case of EMC with those of cribriform AdCC to arrive at morphologic clues to the correct diagnosis. Distinguishing features of EMC on FNA include (1) a prominent population of myoepithelial cells vs the predominance of basaloid cells in AdCC and (2) cohesive matrix globules with a peripheral rim of pale-staining basement membrane material compared with the dyscohesive matrix globules of AdCC. Immunochemical markers (S100, CD117, and MyB) are also useful. Although EMC and AdCC can both contain spherical matrix globules, close evaluation of the cytomorphology of the globules and their relationship to surrounding cells provides a clue to distinguish the two neoplasms. © American Society for Clinical Pathology, 2016.

    Full Text Available Adenoid cystic carcinoma (ACC is characterized by intensive local invasion and high incidence of distant metastases. Conventional chemotherapy for ACC produces a poor result. We aimed to evaluate the effect of apple polyphenols (APs, a novel nutraceutical agent, on the proliferation and apoptosis levels in a metastatic oral ACC cell line. A metastatic ACC (ACC-M cell line and control cells (MRC-5 cells derived from normal lung tissue were treated with APs at different concentrations. MTT assay was used to determine the in vitro cytotoxicity. The cell cycle distribution and apoptosis levels were measured by flow cytometry. To evaluate the mechanism of APs, vascular endothelial growth factor receptor-2 (VEGFR-2 and caspase-3 messenger ribonucleic acid (mRNA and protein levels were evaluated by reverse transcription-polymerase chain reaction and Western blots, respectively. After cells were cultured for 24 hours or 48 hours, the critical concentration of cytotoxicity of APs in MRC-5 cells was found to be 250 μg/mL. In contrast, in the concentration range of 100–250 μg/mL, the cytotoxicity of APs in ACC-M cells was time- and dose-dependent: ACC-M cell proliferation declined at 100 μg/mL when cultured for 48 hours, whereas growth was not inhibited at the concentrations of APs below 200 μg/mL when cultured for 24 hours. In selected time and dose patterns (ACC-M cells cultured at the concentrations of 150 and 250 μg/mL for 48 hours, the flow cytometry performance showed that apoptosis and necrosis occurred in APs-treated ACC-M cells. Also, in these patterns, VEGFR-2 mRNA and protein levels decreased whereas the levels of caspase-3 increased. In summary, APs could inhibit proliferation and induce apoptosis in ACC-M cells in vitro. These effects may be related to the downregulation of VEGFR-2 expression and the activation of caspase-3 expression.

    Adenoid cystic carcinomas (ACC) of the breast are extremely rare tumours, accounting for data exist regarding the correlation of radiological findings with histology of this rare subtype. To our knowledge, gross size discrepancy between the 2 modalities has not been reported. We describe a case of ACC with appreciable size discordance between imaging and pathology report. A 71 years old lady presented with a painless right breast lump of a few months duration. Clinical examination revealed a 1.5 cm right breast upper outer quadrant mass. Axillary and systemic examinations were unremarkable. Mammogram showed an asymmetric density in the right upper outer quadrant which corresponded to a suspicious nodule measuring about 2 cm on the ultrasound. Ultrasound of the axilla showed an indeterminate right lymph node. Core needle biopsy of the right breast nodule showed ACC while the lymph node biopsy was non- metastatic. Staging scans did not reveal any definite distant metastasis. Her naso-endoscopy and MRI of the neck were normal. She underwent a right mastectomy and sentinel lymph node biopsy. Final histology returned as a grade II 55 mm ACC. Lympho-vascular invasion was absent. The tumour was triple negative for Estrogen receptor (ER), Progesterone receptor (PR) and Human epidermal receptor 2 (HER 2). Sentinel lymph node biopsy was negative for metastasis. She recovered well but declined adjuvant chemotherapy and radiation therapy. She is currently well 6 months post operation. ACC is an extremely rare subtype, therefore there are limited reports in literature on its imaging and pathological characteristics. Of this sparse data, there was no mention that there might be a big size discrepancy between the 2 modalities. This appreciable discrepancy has implications for pre-operative planning and the choice of breast surgery. It will be useful if the pathological extent of ACC could be determined more accurately radiologically. However, there are no distinctive

    Adenoid cystic carcinoma (AdCC) is one of the most common salivary gland malignancies and the long-term prognosis is poor. In this study, we examined alterations of AdCC-associated genes, MYB, MYBL1, MYBL2 and NFIB, and their target molecules, including MYC. The results were correlated to clinicopathological profile of the patients. Using paraffin tumour sections from 33 cases of salivary gland AdCC, we performed a detailed fluorescence in-situ hybridization (FISH) analysis for gene splits and fusions of MYB, MYBL1, MYBL2 and NFIB. We found that 29 of 33 (88%) AdCC cases showed gene splits in either MYB, MYBL1 or NFIB. None of the cases showed an MYBL2 gene alteration. AdCCs were divided genetically into six gene groups, MYB-NFIB (n = 16), MYB-X (n = 4), MYBL1-NFIB (n = 2), MYBL1-X (n = 1), NFIB-X (n = 6) and gene-split-negative (n = 4). AdCC patients showing the MYB or MYBL1 gene splits were associated with microscopically positive surgical margins (P = 0.0148) and overexpression of MYC (P = 0.0164). MYC expression was detected in both ductal and myoepithelial tumour cells, and MYC overexpression was associated with shorter disease-free survival of the patients (P = 0.0268). The present study suggests that (1) nearly 90% of AdCCs may have gene alterations of either MYB, MYBL1 or NFIB, suggesting the diagnostic utility of the FISH assay, (2) MYB or MYBL1 gene splits may be associated with local aggressiveness of the tumours and overexpression of MYC, which is one of the oncogenic MYB/MYBL1 targets and (3) MYC overexpression may be a risk factor for disease-free survival in AdCC. © 2017 John Wiley & Sons Ltd.

    Adenoid cystic carcinoma (ACC) is an aggressive cancer with no curative treatment for patients with recurrent/metastatic disease. The MYB-NFIB gene fusion is the main genomic hallmark and a potential therapeutic target. Oncogenic signaling pathways were studied in cultured cells and/or tumors from 15 ACC patients. Phospho-receptor tyrosine kinase (RTK) arrays were used to study the activity of RTKs. Effects of RTK inhibition on cell proliferation were analyzed with AlamarBlue, sphere assays, and two ACC xenograft models (n = 4-9 mice per group). The molecular effects of MYB-NFIB knockdown and IGF1R inhibition were studied with quantitative polymerase chain reaction, immunoblot, and gene expression microarrays. All statistical tests were two-sided. The MYB-NFIB fusion drives proliferation of ACC cells and is crucial for spherogenesis. Intriguingly, the fusion is regulated through AKT-dependent signaling induced by IGF1R overexpression and is downregulated upon IGF1R-inhibition (% expression of control ± SD = 27.2 ± 1.3, P MYB-NFIB regulates genes involved in cell cycle control, DNA replication/repair, and RNA processing. The transcriptional program induced by MYB-NFIB affects critical oncogenic mediators normally controlled by MYC and is reversed by pharmacological inhibition of IGF1R. Co-activation of epidermal growth factor receptor (EGFR) and MET promoted proliferation of ACC cells, and combined targeting of IGFR1/EGFR/MET induced differentiation and synergistically inhibited the growth of patient-derived xenografted ACCs (ACCX5M1, % growth of control ± SD = 34.9 ± 20.3, P = .006; ACCX6, % growth of control ± SD = 24.1 ± 17.5, P = .04). MYB-NFIB is an oncogenic driver and a key therapeutic target in ACC that is regulated by AKT-dependent IGF1R signaling. Our studies uncover a new strategy to target an oncogenic transcriptional master regulator and provide new important insights into the biology and treatment of ACC.

Fluorescence microscopy and transmission electron microscopy were used to observe the autophagic process. Western blot was performed to detect the expression of microtube-related protein 1 light-chain 3 (LC3. An experimental adenoid cystic carcinoma (ACC lung metastasis model was established in nude mice to detect the impacts of SIL on lung weight and lung cancer nodules. Immunohistochemistry was used to detect the expressions of LC3 in human ACC samples and normal salivary gland tissue samples.Results: SIL inhibited the proliferation of ACC-M cells in a dose- and time-dependent manner, and inductively increased the autophagic bodies in ACC-M cells. Furthermore, SIL could increase the expression of LC3 in ACC-M cells and promote the conversion of LC3-I into LC3-II in a dose- and time-dependent manner. In the ACC lung metastasis model, the lung weight and left and right lung nodules in the SIL-treated group were significantly less than those in the control group (P<0.05. The expressions of LC3-I and LC3-II as well as the positive expression rate of LC3 (80% significantly increased, but the positive expression of LC3 in human ACC (42.22% reduced significantly.Conclusion: SIL could inhibit the proliferation and lung metastasis of ACC-M cells by possibly inducing tumor cells autophagy.

    Background The patterns of regional metastasis in adenoid cystic carcinoma (ACC) of the head and neck and its association with outcome is not established. Methods We conducted a retrospective multicentered multivariate analysis of 270 patients who underwent neck dissection. Results The incidence rate of neck metastases was 29%. The rate observed in the oral cavity is 37%, and in the major salivary glands is 19% (p = .001). The rate of occult nodal metastases was 17%. Overall 5-year survival rates were 44% in patients undergoing therapeutic neck dissections, and 65% and 73% among those undergoing elective neck dissections, with and without nodal metastases, respectively (p = .017). Multivariate analysis revealed that the primary site, nodal classification, and margin status were independent predictors of survival. Conclusion Our findings support the consideration of elective neck treatment in patients with ACC of the oral cavity. PMID:25060927

    Full Text Available Adenoid cystic carcinoma (ACC is a relatively rare tumour of the salivary glands, accounting for approximately 5%–10% of all salivary gland tumours. An important feature of ACCs is the long clinical course with a high rate of distant metastases. The preferential sites of metastases are the lung and bone, followed by the brain and liver. Most liver metastases are derived from nonparotid ACCs, and the presentation is often related to local recurrence or metastases to other organs. Solitary metastases to the liver are rare and optimal management is unknown. We present the case of a metastatic ACC to the liver with primary disease presentation at a young age. We discuss our management and other potential treatment modalities.

    Human papillomavirus (HPV) is known as causative for squamous cell carcinoma (SCC) of the oropharynx, but is also found not infrequently in carcinomas of the sinonasal tract. Recently, a subset of these carcinomas was recognized to harbour HPV33 and have a significant morphological overlap with adenoid cystic carcinoma (ACC), a rare and aggressive carcinoma originating in the minor salivary glands. Termed 'HPV-related carcinoma with ACC-like features', only nine cases have been reported. To clarify the occurrence of these tumours we screened a large material for the presence of HPV-related ACC-like carcinoma. The identified tumours were characterized immunohistochemically and with fluorescence in-situ hybridization, and clinicopathological information for all cases is presented. Forty-seven candidate cases were screened for presence of HPV. Six cases were identified and genotyped as HPV types 33, 35, and 56. All six cases had areas of dysplastic mucosal lining and showed remarkable heterogeneous morphologies. MYB, MYBL1, and NFIB genes were intact and, interestingly, staining for MYB protein was largely negative in contrast to what was found in ACC. One patient experienced a local recurrence 11 years after initial treatment and the remaining five patients were alive without evidence of disease. We report six new cases of HPV-related ACC-like carcinoma and found that, although in a small material, the prognosis for these patients seems more favourable than for ACC. For the distinction between ACC and HPV-related ACC-like carcinoma, p16, MYB immunohistochemistry or investigation of MYB, MYBL1 and NFIB gene status are valuable. © 2016 John Wiley & Sons Ltd.

    Cancer-IgG is a newly-discovered molecule, mainly derived from epithelial carcinoma cells and is significantly correlated with differentiation, metastasis, local invasion, and poor prognosis of many cancers. In our previous study we detected IgG expression in oral epithelial carcinoma, including salivary adenoid cystic carcinoma (SACC), using an IgG-specific commercial antibody. Here, we explored the correlation between cancer-IgG and clinicopathological features of SACC. A total of 68 human SACC tissue specimens and 2 siRNAs were used to analyze the correlation between cancer-IgG and extra domain A (EDA(+))-containing fibronectin using the cancer-IgG-specific monoclonal antibody, RP215. We found an unexpected correlation between cancer-IgG and EDA(+) fibronectin, both of which showed aberrant expression in SACC tissue samples. Both were highly expressed in SACC with nerve invasion. In our previous study, EDA(+) fibronectin overexpression in SACC cells decreased N-cadherin expression. In the present study, we used SACC-83 cells, wherein EDA(+) fibronectin is overexpressed and cancer-IgG is knocked down. EDA(+) fibronectin expression was reduced with cancer-IgG knockdown, while cancer-IgG expression did not affect EDA(+) fibronectin overexpression. Furthermore, knockdown of non-B cell-derived IgG in SACC cells decreased cellular motility (PIgG potentially regulates EDA(+) fibronectin expression, thereby suggesting possible new therapeutic approaches for SACC.

    Primary cutaneous adenoid cystic carcinoma (PCACC) is a rare adnexal skin tumor first described in 1975, of which merely 62 cases have so far been studied in detail and reported in the English literature. PCACC is usually regarded as apocrine in origin/differentiation, but its precise histogenesis is still not well known. PCACC has in most cases a rather indolent course but can produce local recurrences and, more rarely, regional (lymph node) and distant (pulmonary) metastases. We report herein a Greek woman with a long-standing PCACC that grew slowly over several years and produced metastasis in the regional lymph nodes, highlighting the potentially aggressive course of this tumor. The primary and metastatic tumors were studied immunohistochemically and proved to express several (sweat gland-related) antigens (such as keratin 7, epithelial membrane antigen, CD10, and CD117) but neither hormonal receptors nor p63 or Gross Cystic disease Fluid Protein 15. The salient clinicopathologic features of this rare cutaneous adnexal tumor are reviewed.

    Adenoid cystic carcinoma (ACC) of the head and neck is a rare but highly malignant tumor. Cancer-testis antigens (CTAs) represent an immunogenic family of cancer-specific proteins and thus represent an attractive target for immunotherapy. Eighty-four cases of ACC were identified, the CTAs pan-Melanoma antigen (pan-MAGE; M3H67) and New York esophageal squamous cell carcinoma (NY-ESO-1; E978) were detected immunohistochemically (IHC) and correlated with clinical data. Expression of NY-ESO-1 was found in 48 of 84 patients (57.1%) and of pan-MAGE in 28 of 84 patients (31.2%). Median overall survival (OS) in NY-ESO-1 positive versus negative patients was 130.8 and 282.0 months (p = .223), respectively. OS in pan-MAGE positive versus negative patients was 105.3 and 190.5 months, respectively (p = .096). Patients expressing both NY-ESO-1 and pan-MAGE simultaneously had significantly reduced OS with a median of 90.5 months compared with 282.0 months in negative patients (p = .047). A significant fraction of patients with ACC show expression of the CTAs NY-ESO-1 and/or pan-MAGE with promising immunotherapeutic implications. © 2016 Wiley Periodicals, Inc.

    The aim of this study was to retrospectively analyse the outcomes of cases of adenoid cystic carcinomas (ACCs) of the head and neck that were treated at a single institution with particle therapy consisting of either protons or carbon ions. Between February 2002 and March 2012, 80 patients were treated with proton therapy (PT) or carbon ion therapy (CIT) alone. PT and CIT were employed in 40 (50%) patients each, and more than half of the patients received 65.0 GyE in 26 fractions (n=47, 59%). The median duration of follow-up was 38 months (range, 6-115 months). For all patients, the 5-year for overall survival (OS) rate, progression-free survival (PFS) rate, and local control (LC) rate were 63%, 39%, and 75%, respectively. No significant differences between PT and CIT were observed. The 5-year LC rates for T4 and inoperable cases were 66% and 68%, respectively. Twenty-one patients (26%) experienced grade 3 or greater late toxicities, including three patients who developed grade 5 bleeding from nasopharyngeal ulcers. Particle radiotherapy for ACC achieves favourable LC, and its efficacy in inoperable or T4 cases is promising. There were no significant differences between PT and CIT in terms of OS, PFS and LC.

    Beclin 1 plays a critical role in autophagy and functions as a haploinsufficient tumor suppressor. The expression and prognostic significance of beclin 1 in head and neck adenoid cystic carcinoma (ACC) are largely unexplored. Therefore, we investigated the expression of beclin 1, Bcl-2, and p53 in head and neck ACC tissue. Tissue samples from 35 cases (15 females, 20 males) of head and neck ACC were utilized for immunohistochemistry. Beclin 1 expression was observed in 32 cases (91.4%) and considered to be high in 15 cases (42.9%) and low in 20 cases (57.1%). Beclin 1 expression was significantly correlated with a histological growth pattern (P=0.046) and histological grade (P=0.037). Beclin 1 expression was inversely correlated with Bcl-2 expression (P=0.013) and significantly associated with overall survival (P=0.006). Bcl-2 and p53 expression were observed in 21 cases (60.0%) and 16 cases (45.7%). Bcl-2 expression was significantly correlated with perineural invasion (P=0.041) and not associated with overall survival (P=0.053). p53 expression was directly correlated with beclin 1 expression (P=0.044). Our results indicated that beclin 1 may be a novel, promising prognostic factor for clinical outcome in head and neck ACC patients and may play a part in the development of head and neck ACC by interacting with Bcl-2 and p53.

  11. Genetic profiling reveals cross-contamination and misidentification of 6 adenoid cystic carcinoma cell lines: ACC2, ACC3, ACCM, ACCNS, ACCS and CAC2.

    Directory of Open Access Journals (Sweden)

    Full Text Available Adenoid cystic carcinoma (ACC is the second most common malignant neoplasm of the salivary glands. Most patients survive more than 5 years after surgery and postoperative radiation therapy. The 10 year survival rate, however, drops to 40%, due to locoregional recurrences and distant metastases. Improving long-term survival in ACC requires the development of more effective systemic therapies based on a better understanding of the biologic behavior of ACC. Much preclinical research in this field involves the use of cultured cells and, to date, several ACC cell lines have been established. Authentication of these cell lines, however, has not been reported. We performed DNA fingerprint analysis on six ACC cell lines using short tandem repeat (STR examinations and found that all six cell lines had been contaminated with other cells. ACC2, ACC3, and ACCM were determined to be cervical cancer cells (HeLa cells, whereas the ACCS cell line was composed of T24 urinary bladder cancer cells. ACCNS and CAC2 cells were contaminated with cells derived from non-human mammalian species: the cells labeled ACCNS were mouse cells and the CAC2 cells were rat cells. These observations suggest that future studies using ACC cell lines should include cell line authentication to avoid the use of contaminated or non-human cells.

    The authors discuss the characteristics and the radiotherapy treatment procedures of cystic adenoid carcinomas, and more precisely the treatment of two of such cases of nasopharyngeal carcinomas. The first one had an incomplete resection surgery followed by curing radiotherapy: he has then been in local-regional control situation for 8 months. The second one had lung metastases, was treated chemotherapy and radiotherapy (decompressive treatment), and died six months after diagnosis. Radiotherapy is considered to be the treatment basis, whereas chemotherapy is a matter of controversy. Short communication

    Adenoid cystic carcinomas (ACCs) from various anatomical sites harbor a translocation t(6;9)(q22-23;p23-24), resulting in MYB-NFIB gene fusion. This gene fusion is not well studied in mammary ACCs, and there are no studies examining this abnormality in solid variant of ACC with basaloid features (SBACC), a high-grade variant thought to behave more aggressively than ACCs with conventional histologic growth. Our aim was to investigate the frequency of MYB-NFIB gene fusion in mammary ACCs with a focus paid to SBACC. MYB rearrangement and MYB-NFIB fusion were assessed by fluorescence in situ hybridization and reverse-transcription polymerase chain reaction, respectively. Histologic features and the presence of MYB rearrangement were correlated with clinical outcome. MYB rearrangement was present in 7 (22.6%) of 31 mammary ACCs (5/15 [33.3%] ACCs with conventional growth; 2/16 [12.5%] SBACCs). One patient with conventional ACC developed distant metastasis, and no patients had axillary lymph node involvement by ACC (mean follow-up, 34 months; range, 12-84 months). Two patients with SBACC had axillary lymph node involvement at initial surgery, and 2 additional patients experienced disease recurrence (1 local, 1 distant; mean follow-up, 50 months; range, 9-192 months). MYB-NFIB fusion status did not correlate with clinical outcome in studied patients. We confirm that MYB-NFIB gene fusion is observed in mammary ACCs and that a subset lacks this abnormality. This study is the first to confirm the presence of MYB rearrangement in SBACC. Additional validation with long-term follow-up is needed to determine the relationship, if any, between MYB-NFIB gene fusion and clinical outcome. Copyright © 2014 Elsevier Inc. All rights reserved.

    In practices, some cases of salivary basal cell tumors that consist mainly of cribriform growth pattern are difficult to differentiate from adenoid cystic carcinoma (AdCC). Identification of reliable molecular biomarkers for the differential diagnosis between them is required. Twenty-two cases of cribriform salivary basal cell tumors (at least 10% cribriform pattern present in each tumor) comprising 18 cases of basal cell adenoma (BCA) and four cases of basal cell adenocarcinoma (BcAC) were collected between 1985 and 2008. Twenty cases of cribriform AdCC were retrieved from our archives. MYB protein expression and gene abnormalities were detected in all cases by immunohistochemistry (IHC) and fluorescent in situ hybridization (FISH) analyses, respectively. Neither MYB protein nor split genes were detected in any of the cases of cribriform basal cell tumors, while 55% (11/20) of cases of cribriform AdCC had MYB protein expression. High MYB expression was detected in 81.8% (9/11) cases, while low expression was found in the remaining cases. FISH analysis indicated that nine AdCC tumors with high MYB protein expression were split gene-positive, while MYB gene splitting was not detected in the 11 cases with low or absent MYB protein expression. The molecular changes in AdCC differ from those associated with cribriform basal cell tumors, which further confirms that cribriform basal cell tumors and AdCC are two distinct tumor entities. Simultaneous detection of MYB protein expression and the associated molecular changes could be beneficial in differentiating salivary cribriform basal cell tumors from AdCC. © 2015 John Wiley & Sons A/S.

    MYB rearrangement is observed in approximately 28% to 86% of adenoid cystic carcinomas (ACCs). Also, ACC features a p63+/p40+ immunophenotype in greater than 90% of cases, compared with p63+/p40- polymorphous low-grade adenocarcinoma (PLGA). Our aim was to investigate the incidence of (1) MYB rearrangement and (2) p63/p40 immunoreactivity in ACC and PLGA of minor salivary glands (MSGs). Seven cases of ACC as well as five of PLGA were evaluated by using a MYB (6 q23.3) break-apart fluorescence in situ hybridization (FISH) probe. In addition, all cases were immunohistochemically stained with p63 and p40 antibodies. All five successfully hybridized ACCs featured MYB rearrangement, whereas PLGAs did not show MYB rearrangement. Interestingly, one case of PLGA demonstrated a single intact copy of MYB in greater than 88% of the neoplastic cells. All ACCs exhibited consistent p63+/p40+ staining, whereas PLGAs demonstrated a p63+/p40- immunophenotype. (1) MYB rearrangement is encountered in ACCs but not PLGAs of MSGs; (2) MYB aberrations, for example, monosomy or deletion, can be seen in PLGAs; (3) combined p63/p40 immunostaining can be used to differentiate ACC from PLGA in incisionally biopsied specimens; and (4) performance of either FISH or p63/p40 immunohistochemistry is expected to be able to confirm the diagnosis of ACC or PLGA in small intraoral biopsies, since both techniques appeared to be diagnostically accurate in this pilot study.

The following features were identified as adverse prognostic factors of RFS on univariate analysis: large tumor size, solid growth pattern, increased mitoses, positive margin, American Joint Committee on Cancer clinical staging, high-grade transformation, vascular invasion, nuclear atypia, open chromatin, prominent nucleoli, and tumor necrosis. However, on multivariate analysis, only increased mitoses (≥5/10 high-power fields), any solid growth pattern, and advanced American Joint Committee on Cancer TNM staging were independent adverse predictors for RFS. MYB immunoexpression and MYB-NFIB translocation were common findings in ACC, occurring in 72% and 59% of the tested ACCs, respectively. The sensitivity and specificity of MYB immunohistochemistry in detecting MYB-NFIB fusion was relatively low at 78% sensitivity and 50% specificity. The high prevalence of alterations leading to high expression of the MYB transcription factor family suggests that targeted approaches developed to suppress the expression of these oncogenic transcription factors and/or the transcriptional activity of these proteins would be a rational therapeutic approach to investigate in ACC.

    The scientific literature to date lacks population-based studies on the demographics, clinical features, and survival of patients with adenoid cystic carcinoma (ACC) of different anatomic sites. The authors identified 5349 patients who had ACC of the major salivary glands (N = 1850), minor salivary glands (N = 2077), breast (N = 696), skin (N = 291), lung and bronchus (N = 203), female genital system (N = 132), and eye and orbit (N = 100) from the Surveillance, Epidemiology, and End Results (SEER) registry. Differences in demographics, clinical features, and survival of patients were assessed. ACC of the eye and orbit was associated with younger age at presentation (mean age,49.9 years). ACC of the skin or breast tended to present with less aggressive prognostic features, whereas ACC of the lung and bronchus or eye and orbit tended to present with more aggressive prognostic features. In a multivariate survival analysis of patients who presented with localized disease, patients with ACC of the breast (hazard ratio [HR], 0.40) or skin (HR, 0.40) had a significantly lower risk death than patients with ACC of the major salivary glands; whereas patients with ACC of the lung and bronchus (HR, 3.72) or the eye and orbit (HR, 3.67) had a significantly higher risk. For patients who presented with regional disease, the only clear prognostic difference in multivariate analysis was that patients with ACC of skin fared significantly better. The demographics and clinical features of patients with ACC differ by disease site. The current results indicated that site may be an important predictor of survival for patients who present with localized disease but is less important for patients who present with regional disease.

  19. Adenoid basal hyperplasia of the uterine cervix: a lesion of reserve cell type, distinct from adenoid basal carcinoma.

    Adenoid basal hyperplasia is an underrecognized cervical lesion, resembling adenoid basal carcinoma, except the absence of deep invasion into the stroma. We report a series of 10 cases, all extending less than 1 mm from the basement membrane. Our results support the hypothesis that adenoid basal hyperplasia arises from reserve cells of the cervix. Lesions were found close to the squamocolumnar junction, in continuity with the nearby subcolumnar reserve cells. They shared the same morphology and immunoprofile using a panel of 4 antibodies (keratin 5/6, keratin 14, keratin 7 and p63) designed to differentiate reserve cells from mature squamous cells and endocervical columnar cells. We detected no human papillomavirus infection by in situ hybridization targeting high-risk human papillomavirus, which was concordant with the absence of immunohistochemical p16 expression. We demonstrated human papillomavirus infection in 4 (80%) of 5 adenoid basal carcinoma, which is in the same range as previous studies (88%). Thus, adenoid basal hyperplasia should be distinguished from adenoid basal carcinoma because they imply different risk of human papillomavirus infection and of subsequent association with high-grade invasive carcinoma. In our series, the most reliable morphological parameters to differentiate adenoid basal hyperplasia from adenoid basal carcinoma were the depth of the lesion and the size of the lesion nests. Furthermore, squamous differentiation was rare in adenoid basal hyperplasia and constant in adenoid basal carcinoma. Finally, any mitotic activity and/or an increase of Ki67 labeling index should raise the hypothesis of adenoid basal carcinoma. Copyright © 2012 Elsevier Inc. All rights reserved.

    Because immunohistochemical features of adenoid squamous cell carcinoma (AdSCC) of the oral cavity is unclear, the author reports herein AdSCC in the gingival with an emphasis on immunohistochemical features. A 73-year-old woman presented with a left lower gingival tumor. The tumor was mildly elevated tumor measuring 1.5 x 1.5 x 0.5 cm. Dentist's diagnosis was granulation tissue, and a biopsy was taken. The biopsy showed proliferation of carcinoma cells arranged in cords, and squamous and tubular differentiations were noted in places. The biopsy diagnosis was adenosquamous carcinoma. Tumor excision with resection of mandibular bone was performed. The resected tissue showed a mixture and squamous cell carcinoma and tubular formation. Gradual merges between the two and acantholytic features of the squamous cell carcinoma element were seen. Both components were free from mucins. Both components were positive for pancytokeratins (AE1/3, CAM5.2) +++, cytokeratin (CK) 5/6 +, CK34βE12 ++, CK7 +, CK14 +++, CEA +, CA19-9 +, CA125 +, p53 +++, p63 +++, KIT + and MUC1 ++. Both components were negative for CK8, CK18, CK19, CK20, EMA, vimentin, TTF-1, desmin, myoglobin, S100 protein, melanosome, smooth muscle actin, CD34, CDX2, CD10, chromogranin, synaptophysin, NSE, CD56, lysozyme, CD68, MDM2, PDGFRA, MUC2, MUC5AC, and MUC6. Since both components were positive for squmaous cell carcinoma markers (CD5/6, CK34βE12, and p63) and adenocarcinoma markers (CEA, CA19-9, CA125, MUC1), this case of AdSCC appears an intermediate form between adenocarcinoma and squamous cell carcinoma. The margins were negative. No metastasis was found by imaging techniques. The patient is now free from tumor and is followed up carefully.

    Intracystic papillary carcinoma of the breast (ICP) is a rare form of noninvasive breast cancer. The average age of onset is 65 years. Patients with ICP have a greater than 15-year survival rate advantage compared to patients with other breast carcinomas. There have been no reports of disease-related deaths in patients with ICP and no increased risk of disease in the contralateral breast. No definitive conclusions have been made regarding adjuvant treatment; however, ICP should generally be treated like ductal carcinoma in situ (DCIS). Tamoxifen is often recommended.

    The aim of this study was to determine the prevalence and amount of cystic change in thyroid cancer. This study also examined associated sonographic characteristics of cystic malignant thyroid nodules to help recognize these clinically important nodules. This study was a retrospective review of 360 malignant thyroid nodules surgically removed at our institution between January 1, 2002 and December 31, 2004. All patients had signed research authorization. All patients had preoperative sonograms and surgical pathologic proof of their thyroid malignancy. The 360 malignant nodules were found in 307 patients. All scans were performed using 7- to 15-MHz transducers, and most studies included a digital video clip of the cancer. The preoperative ultrasound examinations were retrospectively reviewed by three radiologists and a sonographer. An estimate of cystic component percentage was derived by consensus. The presence of a mural nodule, thick irregular wall, microcalcifications, and prominent vascularity was also recorded. Of the 360 carcinomas, 318 (88.3%) were solid to minimally (less than 5%) cystic, 33 (9.2%) were 6-50% cystic, 9 (2.5%) were 51-100% cystic. Of the nine (2.5%) malignancies that were greater than 50% cystic, all had other suspicious findings including mural nodules, microcalcifications, increased vascularity, and/or a thick irregular wall about the cystic portion. The vast majority (88%) of thyroid cancer is uniformly solid or has minimal (1-5%) cystic change by sonography. Marked cystic change (>50% of the nodule) occurred in only 2.5% of cancers, which had other sonographic findings worrisome for malignancy.

    Full Text Available Abstract Background The pathogenesis of salivary gland carcinomas is very complex and prognostic markers are difficult to find in these carcinomas of which the different subtypes have varying malignant potential. The study was conducted to examine the cellular distribution of maspin and MCM2 in salivary gland carcinomas and their value to predict lymph node metastasis. Materials and methods Fifty three paraffin blocks of different lesions (15 muco-epidermoid carcinoma, 14 adenoid cystic carcinoma, 3 epi-myoepithelial carcinoma, 5 salivary duct carcinoma, 5 malignant pleomorphic adenoma, 6 polymorphous low grade adenocarcinoma and 5 acinic cell carcinoma were prepared for immunohistochemical staining with maspin and MCM2 antibodies. ANOVA and Pearson correlation tests were used for the statistical analysis of the results. Results All salivary gland carcinomas express maspin and MCM2 with variable cellular localization. There was a significant difference in the expression of each antibody between mucoepidermoid carcinoma, adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. No association was found between examined markers and lymph node metastasis. Conclusions Salivary gland carcinomas express maspin and MCM2 with variable levels and cellular localization, consisting important markers of biological behavior in these tumors. The level of MCM2 expression can be used in the differential diagnosis of adenoid cystic carcinoma and polymorphous low grade adenocarcinoma. Further study with large sample size is recommended to assess their value in prediction of lymph node metastasis.

The patient suffered the two major complications related with acquired renal cystic disease; hemorrhage and renal carcinoma. Our case is a patient with acquired renal cystic disease, single kidney after surgery for renal clear cell carcinoma four years earlier, who developed a Wünderlich syndrome (WS). The histological study of the nephrectomy specimen showed a renal papillary carcinoma in the context of acquired renal cystic disease after surgery for a WS. Renal hemorrhage is a serious complication that can lead to a fatal outcome. Patients undergoing dialysis should be monitored actively due to the risk of developing acquired renal cystic disease and associated complications.

    Basaloid tumors of the salivary gland both benign and malignant comprise ACC, cellular PA, basal cell adenoma (BCA), and basal cell adenocarcinoma. Rendering a diagnosis given a limited biopsy or fine needle aspiration (FNA) sample proves challenging. Activation of MYB by gene fusion has been found in salivary gland ACCs; therefore we investigated the utility of MYB immunohistochemistry (IHC) as a tool for distinguishing ACCs from other basaloid neoplasms. We selected 48 cases of ACC (11 FNA blocks [CB]), 37 histologic resections [HR]), 74 PA (36 CB, 38 HR), and 18 BCA (7 CB, 11 HR). FNA CB showed 82% of ACCs (N = 9 of 11) as positive for MYB nuclear staining whereas 68% of ACCs (N = 25 of 37) were positive in HR. All PA were negative for MYB nuclear staining in both CB (N = 0 of 36) and HR (N = 0 of 38). CB showed 29% of BCA (N = 2 of 7) as positive for MYB nuclear staining and 55% (N = 6 of 11) positive in HR. Both ACC and BCA showed significantly higher mean staining intensity than PA in both CB and HR (P MYB nuclear staining may prove useful in separating ACC from PA and BCA, especially in limited cellular samples.

    To investigate the image features and the diagnostic value of spiral CT for cystic renal cell carcinoma. The clinical data and CT manifestations of 17 operated and pathologically proven cystic renal cell carcinoma were retrospectively analyzed. There were 12 males and 5 females with an average age of 47.3 years (33 - 82 years). Plain and contrast CT scan (Siemens somatom) single layer sensation 16 layer spiral CT had been performed before operation. The image of artery phase (30 - 40 s), venous (60 - 70 s) and excretory (120 - 180 s) were respectively obtained after contrast administration. Various image reconstructions were done using Siemens Wizard workstation based on the raw images. It was found that 5 cystic renal cell cancers located in the right kidney and 12 in the left kidney. The long dimension of the tumor arranged from 21 - 100 mm with an average of 57 mm. The tumor looked like a round or round-like shape with density similar to fluid on plain CT scan. Some cystic renal carcinomas had a thick wall. Some had single or multiple cystic spaces filled with fluid of different densities. Some had infiltrated out of kidney surface or into renal sinus. Some showed enhanced nodules on the wall. Cystic renal cell carcinoma has its own specific morphologic features in spiral CT scan. Spiral CT may be very helpful in the diagnosis of cystic renal cell carcinoma before operation.

    Most medullary thyroid carcinomas show suspicious malignant features such as hypoechogenicity, a spiculated margin and/or intranodular calcifications, which are well known features of papillary carcinoma. We report here on a case of medullary carcinoma that was seen as a predominantly cystic thyroid mass on ultrasonography. This type of case is not common in the literature and we discuss the way to diagnose a medullary thyroid carcinoma

    Multicystic dysplastic kidney is a common cystic renal disease that often occurs in infancy. Recent studies demonstrate the possibility for spontaneous involution of a dysplastic kidney. In such cases, the prognosis is generally excellent and there is a very low incidence of complications. Complications associated with multicystic dysplastic kidney include pain, infection, hypertension, and neoplasia. Renal cell carcinomas are extremely rare in multicystic dysplastic kidneys. To our knowledge, no case report has described a radiologic finding of renal cell carcinoma arising from an involutional multicystic dysplastic kidney. We report a case of histopathologically validated cystic papillary renal cell carcinoma arising from an involutional multicystic dysplastic kidney and describe its sonographic and CT features.

    Purpose: This study was designed to evaluate the safety of chemotherapeutic infusion or chemoembolization by way of the cystic artery in patients with hepatocellular carcinoma (HCC) supplied exclusively by the cystic artery. Methods: Between Jan 2002 and Dec 2011, we performed chemotherapeutic infusion or chemoembolization using iodized oil for the treatment of 27 patients with HCC supplied exclusively by the cystic artery. Computed tomography (CT) scans, digital subtraction angiograms, and medical records were retrospectively reviewed by consensus. Results: The cystic artery originated from the main right hepatic artery in 24 (89 %) patients, from the right anterior hepatic artery in 2 (7 %) patients, and from the left hepatic artery in 1 (4 %) patient. Selective catheterization of the cystic artery was achieved in all patients. Superselection of tumor-feeding vessels from the cystic artery was achieved in 7 patients (26 %). Chemotherapeutic infusion was performed in 18 patients (67 %), and chemoembolization was performed in 9 patients (33 %). There were no major complications and only 2 minor complications, including vasovagal syncope and nausea with vomiting. Individual tumor response supplied exclusively by the cystic artery at the follow-up enhanced CT scan were complete response (n = 16), partial response (n = 3), and stable disease (n = 8). Conclusion: HCC supplied exclusively by the cystic artery can be safely treated without severe complications by chemotherapeutic infusion or chemoembolization using iodized oil through the cystic artery.

    A case of multilocular cystic renal cell carcinoma was reported. The patient was 69-year-old male who had been examined for postoperative study of gastric cancer by abdominal CT. The abdominal CT incidentally revealed right adrenal tumor which was non-functional and multilocular cysts in the lower pole of the right kidney. Selective renal arteriography showed a hypovascular mass with fine neovascularity. These two findings of CT and arteriography were though to represent a probable malignant tumor but renal function of the patient decreased moderately. Surgical exploration was done and right renal masses were thought to be seen benign multilocular cysts without capsule. Simple excision of the wall of cysts and right adrenalectomy were performed. Pathological examinations showed multilocular cystic renal cell carcinoma and benign adrenal hyperplasia. Additionally partial nephrectomy was done. Surgical margin of the kidney was tumor free and postoperative course was uneventful. Prognosis of multiocular cystic renal cell carcinoma is good, therefore conservative surgery is recommended.

    Full Text Available Background: Cystic papillary thyroid carcinoma (CPTC is a variant of papillary carcinoma that has many mimickers in cytological grounds. Aim: To study the cytomorphologic features of CPTC and compare them to those of other cystic thyroid lesions using fine-needle aspiration cytology (FNAC. We also aimed to identify the cytomorphologic features that distinguish CPTC from other cystic thyroid lesions. Materials and Methods: Seventy-three cases of CPTC were included in the study. The cytomorphologic features of these cases were analyzed. The FNA smears of other thyroid lesions with cystic changes (300 colloid goiters, 290 adenomatoid nodules, 11 follicular neoplasms, and 9 hurtle cell neoplasm were also studied. Results: The smears in CPTC revealed isolated follicular cells, small groups of cells with scalloped margins, cell swirls, small clusters with a cartwheel pattern, papillary clusters, intranuclear inclusions, nuclear grooves, sticky colloid, intracellular colloids, psammoma bodies, multinucleated giant cells, and foamy and hemosiderin laden macrophages. Small groups of cells with scalloped borders, cellular swirls, and small clusters with a cartwheel pattern were seen in CPTC, but not in other cystic lesions. Interestingly, mesothelial-like cells and hemophagocytic cells were seen in five and three cases of CPTC, respectively, but not in other cystic lesions. Conclusion: Mesothelial-like cells and hemophagocytic cells were observed in five and three cases of CPTC, respectively. Similar finding have not been previously reported in the literature.

    To investigate the characteristics of papillary thyroid carcinoma (PTC) with cystic changes visible on ultrasonography (US). This study included 553 PTCs in 553 patients between January 2003 and August 2004. One radiologist with 10 years of experience in thyroid imaging retrospectively reviewed the preoperative US images. Two different groups were formed according to two different reference points (group 1, 25%; group 2, 50%) of the cystic component. Patients between the groups were compared according to their clinicopathologic characteristics. Disease-free survival (DFS) was estimated. Cox's multivariate proportional hazards regression model was used to identify the effect of variable factors on the recurrence risk. Fifty-six patients (10.1%) were confirmed to have tumor recurrence within the follow-up period. Thirty-five patients had regional metastasis, one had distant metastasis, eight had multiple site metastases, and 12 had biochemical recurrence. PTC patients with a ≤ 50% or PTC patients with a ≤ 25% cystic component did not have a statistically significant longer DFS than those with a >50% (hazard ratio [HR], 1.118; 95% confidence interval [CI], 0.255 to 4.910; P=0.883) or those with a >25% cystic component (HR, 0.569; 95% CI, 0.164 to 1.976; P=0.375), respectively. Moreover, independent predictors of recurrence were pathologic size, male gender, and lymph node metastasis, not a >50% or >25% cystic component. The proportion of the cystic component in PTCs did not affect DFS.

    Cystic renal cell carcinoma (cystic RCC) is thought to carry an improved prognosis relative to clear cell RCC (CCRCC); however, this is based on small case series. We used a population-based tumor registry to compare clinicopathologic features and cancer-specific mortality (CSM) of cystic RCC with those of CCRCC. The Surveillance, Epidemiology, and End Results database was queried for all patients diagnosed and treated for cystic RCC and CCRCC between 2001 and 2010. Clinical and pathologic factors were compared using t tests and chi-square tests as appropriate. Kaplan-Meier survival analysis compared CSM differences between cystic RCC and CCRCC. A total of 678 patients with cystic RCC and 46,677 with CCRCC were identified. The mean follow-up duration was 52 and 40 months, respectively. When compared with CCRCC patients, those with cystic RCC were younger (mean age 58 vs. 61 y, P < 0.001), more commonly black (22% vs. 9%, P < 0.001), and female (45% vs. 41%, P = 0.02). Cystic RCCs were more commonly T1a tumors (66% vs. 55%, P < 0.001), well differentiated (33% vs. 16%, P < 0.001), and smaller (mean size = 3.8 vs. 4.5 cm, P < 0.001). Cystic RCC was associated with a reduction in CSM when compared with CCRCC (P = 0.002). In a subset analysis, this reduction in CSM was seen only for those with T1b/T2 tumors (P = 0.01) but not for those with T1a RCCs lesions (P = 0.31). We report the largest series of cystic RCC and corroborate the findings of improved CSM when compared with CCRCC for larger tumors; however, no difference was noted in smaller tumors, suggesting that tumor biology becomes more relevant to prognosis with increasing size. These data may suggest a role for active surveillance in appropriately selected patients with small, cystic renal masses. Copyright © 2015 Elsevier Inc. All rights reserved.

    2008-04-01

    A unique case of cystic hypersecretory carcinoma in a 48-year-old woman who presented with a tender, palpable abnormality of the lower outer quadrant of her left breast in 2002 is described. Mammographic and ultrasound examinations showed heterogeneous, dense breast tissue with a focal asymmetric density and an ill-defined heterogenous hypoechoic area with anechoic spaces, respectively, that corresponded to the area of palpable abnormality. Although the imaging findings did not change significantly over 4 years, the patient complained of intermittent, spontaneous serous discharge from the left nipple and persistent induration and tenderness in the same area of the left breast. An ultrasound-guided core-needle biopsy of the lesion was performed at the last visit to rule out a malignant process. A left simple mastectomy showed a large multicystic lesion occupying most of the lower quadrants by a cystic hypersecretory carcinoma and Paget disease of the nipple.

    Mammary analogue secretory carcinoma (MASC) is a recently described salivary gland tumor that has morphologic features similar to secretory carcinoma of the breast and that also harbors the same ETV6 translocation. Diffuse mammaglobin and S-100 immunoreactivity are used to differentiate MASC from its morphologic mimics, especially acinic cell carcinoma and adenocarcinoma, not otherwise specified. However, the combination of mammaglobin and S-100 immunoreactivity has not been well studied in other types of salivary gland carcinomas that may have focal areas reminiscent of MASC. Here we evaluated mammaglobin and S-100 immunoreactivity in 15 cases each of polymorphous low-grade adenocarcinoma, adenoid cystic carcinoma and mucoepidermoid carcinoma, and also in 2 cases of adenocarcinoma, not otherwise specified, and 1 mucinous adenocarcinoma. Cases with significant co-expression of mammaglobin and S-100 (moderate or strong immunoreactivity in >25% of tumor cells) were further analyzed by fluorescence in situ hybridization using the ETV6 (12p13) break-apart probe. Nine cases (60%) of polymorphous low-grade adenocarcinoma and two (13.3%) of adenoid cystic carcinoma met the criteria for significant co-expression of mammaglobin and S-100. All were negative for the ETV6 translocation by fluorescence in situ hybridization. Although mammaglobin and S-100 positivity was seen in the majority of polymorphous low-grade adenocarcinomas and a minority of adenoid cystic carcinomas, none were positive for the ETV6 translocation characteristic of MASC. This indicates a need for caution in the use of immunohistochemistry for diagnosing MASC, especially in the absence of cytogenetic confirmation. © 2013.

    Breast cysts are mainly benign and are reported in association with fibrocystic disease and phyllodes tumor. Rarely have cystic changes been reported to occur in malignant tumors. They are usually small but large in rare cases. Giant breast cysts are very rare, and only a few cases have been reported. A 37-year-old woman presented with a rapidly growing breast mass. Mammography showed a huge, well-circumscribed cystic mass (17 x 16 x 16 cm) suggestive of a benign lesion. Cytologic examination revealed a highly cellular tumor composed of malignant cells of various sizes and shapes in a necrotic background. The smears were diagnosed as positive for malignancy and suggested metaplastic carcinoma. Mastectomy was performed, and histologic study confirmed the cytologic diagnosis. This is the first reported case of a breast cyst of this size. Clinically the cyst was confused with a benign lesion. The fine needle aspiration aided the diagnosis and planning of treatment.

    In recent years, human papillomavirus (HPV)-positive oropharyngeal carcinomas have been increasing. The first manifestation of these tumors is frequently as cystic metastasis to cervical lymph nodes that may precede recognition of the primary tumor, so, they often result in misdiagnosis as branchial cleft cysts. We report a case of cystic cervical lymph node metastasis of HPV-positive tonsil cancer. The patient was a 70-years-old man who noticed a mass on his left neck. The tumor was large and soft, and it was diagnosed as benign in fine-needle aspiration cytology. We diagnosed the tumor as a branchial cleft cyst and undertook surgery. The histopathological diagnosis was squamous cell carcinoma arising from a branchiogenic cyst. However, because it did not satisfy the diagnostic criteria, we diagnosed the tumor as an unknown primary tumor. One year later, left tonsil cancer was suspected based on PET-CT imaging and a left tonsillectomy was undertaken, whereafter tonsil cancer was found. In p16 immunostaining, it was positive in both cystic mass and tonsil. The cervical mass was cystic lymph node metastasis of HPV-positive tonsil cancer. It is important to investigate the oropharynx, when we found cystic cervical mass, because HPV-positive oropharyngeal carcinoma frequently results in cystic neck metastasis.

    Renal oncocytoma (RO) may present with a tubulocystic growth in 3% to 7% of cases, and in such cases its morphology may significantly overlap with tubulocystic renal cell carcinoma (TCRCC). We compared the morphologic and immunohistochemical characteristics of these tumors, aiming to clarify the differential diagnostic criteria, which facilitate the discrimination of RO from TCRCC. Twenty-four cystic ROs and 15 TCRCCs were selected and analyzed for: architectural growth patterns, stromal features, cytomorphology, ISUP nucleolar grade, necrosis, and mitotic activity. Immunohistochemical panel included various cytokeratins (AE1-AE3, OSCAR, CAM5.2, CK7), vimentin, CD10, CD117, AMACR, CA-IX, antimitochondrial antigen (MIA), EMA, and Ki-67. The presence of at least focal solid growth and islands of tumor cells interspersed with loose stroma, lower ISUP nucleolar grade, absence of necrosis, and absence of mitotic figures were strongly suggestive of a cystic RO. In contrast, the absence of solid and island growth patterns and presence of more compact, fibrous stroma, accompanied by higher ISUP nucleolar grade, focal necrosis, and mitotic figures were all associated with TCRCC. TCRCC marked more frequently for vimentin, CD10, AMACR, and CK7 and had a higher proliferative index by Ki-67 (>15%). CD117 was negative in 14/15 cases. One case was weakly CD117 reactive with cytoplasmic positivity. All cystic RO cases were strongly positive for CD117. The remaining markers (AE1-AE3, CAM5.2, OSCAR, CA-IX, MIA, EMA) were of limited utility. Presence of tumor cell islands and solid growth areas and the type of stroma may be major morphologic criteria in differentiating cystic RO from TCRCC. In difficult cases, or when a limited tissue precludes full morphologic assessment, immunohistochemical pattern of vimentin, CD10, CD117, AMACR, CK7, and Ki-67 could help in establishing the correct diagnosis.

    The initial and follow-up CT and MRI images of ten patients with hepatic metastases from ovarian tumors were retrospectively analyzed to establish their features and sequential changes in appearance. Ten patients with hepatic metastasis from ovarian tumors received initial and follow-up CT and MRI examinations. Six patients were followed up every two to three weeks before surgical tumor resection. Both CT and MR images were analyzed by two radiologists. A total of fourteen lesions were detected by CT and MRI in 10 patients. All 14 lesions were demonstrated as areas of marked hyperintensity on T2-weighted MRI. Eleven cyst-like tumors were demonstrated as round or oval low density lesions on CT and as areas of hypointensity on T1-weighted imaging. Three lesions were shown as solid masses with slightly low attenuation at the initial CT examination and slightly low or iso-intensity areas on T1-weighted imaging, and these lesions showed early peripheral globular enhancement and delayed enhancement on contrast-enhanced CT and MR imaging. Cystic formation was observed two to three weeks later after initial study in all the 3 solid lesions. Rapid subcapsular effusion, which showed obvious enhancement on delayed Gd-DTPA enhanced MR imaging, was observed in two patients. The hepatic metastatic tumor from cystic ovarian carcinoma may manifest as a well-defined cystic lesion or as a solid mass, and the solid mass shows delayed enhancement on contrast-enhanced CT and MR imaging. Furthermore, rapid cystic formation and rapid subcapsular extension is frequently seen. (author)

    We investigated the reliability of combined DOG1 and mammaglobin immunohistochemistry compared with ETV6 fluorescence in situ hybridization (FISH) in the assessment of salivary tumors previously diagnosed as acinic cell carcinoma (ACC). Ultrastructural features of cases reclassified as mammary analogue secretory carcinoma (MASC) were assessed by transmission electron microscopy (TEM). Immunohistochemical (IHC) reactivity to DOG1 and mammaglobin was validated against FISH targeting the ETV6 gene in all 14 cases. Three cases with papillary cystic histomorphology previously diagnosed as ACC were revised to MASC. TEM features of the ETV6 rearrangement-positive MASC cases showed large numbers of secretory granules with extrusion into the intercellular spaces, well-developed endoplasmic reticulum, lipid-laden vacuoles, well-formed microvilli, and large lining cystic spaces. Combined DOG1 and mammaglobin immunohistochemistry is comparable to ETV6 -breakapart analysis for differentiating between papillary cystic variants of ACC and MASC.

    Mammary analog secretory carcinoma (MASC) of the salivary gland has been recently described according to morphological, immunohistochemical, and molecular (ETV6-NTRK3 translocation) similarities with the mammary secretory carcinoma. The most important differential diagnostic considerations of MASC are low-grade adenocarcinoma not otherwise specified (NOS), cystadenocarcinoma, and acinic cell carcinoma (AciCC). These tumors may share an overlapping morphology with MASC, and additional immunohistochemical studies are required to reinforce the diagnosis. Mammaglobin, GCDFP-15, and p63 staining have been reported in MASC. Our study was designed to check the specificity of these antibodies in MASC compared to other frequent tumors of salivary glands. A series of 62 salivary gland tumors [10 MASCs, 5 adenocarcinomas NOS and 2 cystadenocarcinomas with MASC features and without ETV6 rearrangement, one low-grade cribriform cystadenocarcinoma (LGCCC), 9 AciCCs, 10 MECs, 10 adenoid cystic carcinomas (AdeCCs), 5 polymorphous low-grade adenocarcinomas (PLGAs), and 10 pleomorphic adenomas (PAs)] was analyzed by immunohistochemistry with mammaglobin, GCDFP-15, and p63 antibodies. Positivity for mammaglobin was observed in all MASCs, cystadenocarcinomas, LGCCC, and PLGAs, in some adenocarcinomas NOS, PAs, and MECs, rarely in AciCCs and never in AdeCCs. Positivity for GCDFP-15 was observed in most of the tumor types except in AdeCCs. Interestingly, cytoplasmic positivity for p63 was observed in most of MASCs and PLGAs while rarely in adenocarcinomas NOS and PAs, and never in the other tumor types. Our study revealed the usefulness of mammaglobin and p63 cytoplasmic staining to define which tumors are worth to be screened for ETV6 rearrangement. © 2014 John Wiley & Sons A/S.

A retrospective study was conducted in all women diagnosed with breast cancer at our institution from January 2005 to February 2016. Patients with diagnosis of salivary gland-like breast carcinomas were included. In this period, 6384 patients were diagnosed with breast cancer at our institution; salivary gland-like carcinomas were found in 7 patients (0.1%), adenoid cystic carcinoma was diagnosed in 5 patients (0.07%), acinic cell carcinoma in 1 patient (0.015%) and mucoepidermoid carcinoma in 1 patient (0.015%). The triple-negative subtype was found in all of the tumors. Median follow-up was 66.3 months (range, 1-108 months). No patient developed local or distant recurrence. Salivary gland-like breast tumors are extremely rare. We found a global incidence of 0.1%. Adenoid cystic, acinic cell and mucoepidermoid carcinomas were the three histologic types diagnosed. Although the triple-negative subtype is mainly found, good prognosis is expected. Copyright © 2016 Elsevier GmbH. All rights reserved.

    Full Text Available Introduction:Most metastatic lymph nodes from head and neck malignancy are solid. Cystic nodes are found in 33% - 61% of carcinomas arise from Waldeyer’s ring, of which only 1.8% - 8% originate are from the nasopharynx. Some cystic cervical metastases were initially presumed to be branchial cleft cyst. This case report aims to highlight the unusual presentation of cystic cervical metastasis secondary to nasopharyngeal carcinoma in a young adult. The histopathology, radiological features and management strategy were discussed. Case Report:A 36-year-old man presented with a solitary cystic cervical swelling, initially diagnosed as branchial cleft cyst. Fine needle aspiration yielded 18 ml of straw-coloured fluid. During cytological examination no atypical cells were observed. Computed tomography of the neck showed a heterogeneous mass with multiseptation medial to the sternocleidomastoid muscle. Histopathological examination of the mass, post excision, revealed a metastatic lymph node. A suspicious mucosal lesion at the nasopharynx was detected after repeated thorough head and neck examinations and the biopsy result confirmed undifferentiated nasopharyngeal carcinoma. Conclusion:Cystic cervical metastasis may occur in young patients under 40 years. The primary tumour may not be obvious during initial presentation because it mimicks benign branchial cleft cyst clinically. Retrospective review of the computed tomography images revealed features that were not characteristic of simple branchial cleft cyst. The inadequacy of assessment and interpretation had lead to the error in diagnosis and subsequent management. Metastatic head and neck lesion must be considered in a young adult with a cystic neck mass.

  16. Cystic nodal metastasis in patients with oropharyngeal squamous cell carcinoma receiving chemoradiotherapy: Relationship with human papillomavirus status and failure patterns.

    Full Text Available We investigated the relationships of cystic nodal metastasis, human papillomavirus (HPV status, and treatment failure patterns in patients with oropharyngeal squamous cell carcinoma (OPSCC treated with chemoradiotherapy.We retrospectively reviewed pretreatment MRI and clinical courses of patients with OPSCC whose tumors were tested for HPV-induced p16 expression via immunohistochemistry and who completed chemoradiotherapy. Cervical cystic nodal metastasis and necrotic nodal metastasis were classified on MRI.Of 98 patients eligible for analysis, 33 were p16-positive. Cystic nodal metastasis was significantly more prevalent in p16-positive than in p16-negative patients (39.4% versus 18.5%, respectively; p = 0.025. Necrotic nodal metastasis was significantly more prevalent in p16-negative than in p16-positive patients (73.8% versus 51.5%, respectively; p = 0.027. On multivariate analysis, necrotic nodal metastasis (odds ratio [OR] = 7.310, p = 0.011 was an independent predictor of regional failure, while advanced nodal stage (OR = 4.119, p = 0.022 and cystic nodal metastases (OR = 0.087, p = 0.026 were independent positive and negative predictors of distant failure, respectively.Cervical cystic and necrotic nodal metastases are associated with HPV-induced p16-positive and p16-negative OPSCC, respectively. Patients with necrotic nodal metastasis at presentation have an increased risk of regional failure. Distant failure is directly and inversely correlated with advanced nodal stage and cystic nodal metastasis, respectively.

    Renal cell carcinoma (RCC) is derived from renal tubular epithelial cells and represents approximately 3.8% of all malignancies in adults. The incidence of renal cell carcinoma has been growing steadily and ranging from 0.6 to 14.7 for every 100,000 inhabitants. Patients with end-stage renal disease and acquired cystic kidney disease are at increased risk of developing RCC while undergoing dialysis treatment or after renal transplantation. We presented 3 patients undergoing hemodialysis, with acquired cystic kidney disease accompanied by the development of RCC. In all the patients tumor was asymptomatic and discovered through ultrasound screening in 2 patients and in 1 of the patients by post-surgery pathohistological analysis of the tissue of the kidney excised using nephrectomy. All the three patients had organ-limited disease at the time of the diagnosis and they did not require additional therapy after surgical treatment. During the follow-up after nephrectomy from 6 months to 7 years, local recurrence or metastasis of RCC were not diagnosed. Acquired cystic kidney disease represents a predisposing factor for the development of renal cell carcinoma in dialysis patients and requires regular ultrasound examinations of the abdomen aimed at early diagnosis of malignancies. Prognosis for patients with end-stage renal disease and RCC is mostly good because these tumors are usually of indolent course.

    GATA3 is a transcription factor, which is involved in the growth and differentiation of several human tissues. Immunohistochemical staining for this marker has proven to be useful in recognizing a number of tumors, most notably those in the urinary tract and breasts. To date, no study has specifically assessed the distribution of GATA3 among different histomorphologic subtypes of breast carcinoma. The surgical pathology archive at our institution was searched, to retrieve cases of breast carcinomas of the following microscopic types-ductal, lobular, mucinous, metaplastic, medullary, apocrine, signet-ring cell, and micropapillary. Tissue microarrays were created, with four 0.6-mm punch specimens from each case. The tissue microarrays were cut at a 5-μm thickness and stained with monoclonal antibodies to GATA3 (Biocare Medical Inc, Concord, CA), mammaglobin (Dako, Carpinteria, CA), and gross cystic disease fluid protein 15 (Dako). Tumors were considered to be positive for those markers if more than 5% of the cells were labeled. Of 55 ductal adenocarcinomas, 51 (92.7%) expressed GATA3. All 4 GATA3-negative tumors were Nottingham grade III lesions that were also nonreactive for estrogen receptor protein. GATA3 was present in 28 (96.6%) of 29 lobular adenocarcinomas, 10 (90.9%) of 11 apocrine adenocarcinomas, 10 (83.3%) of 12 medullary carcinomas, 5 (55.5%) of 9 metaplastic carcinomas, and 1 of 2 signet-ring cell carcinomas. Mucinous carcinomas (23 cases) and micropapillary carcinomas (12 cases) uniformly and strongly labeled for GATA3. GATA3 equaled or surpassed the sensitivity of mammaglobin and gross cystic disease fluid protein 15 in all histologic subgroups of breast cancer in the study. Although most ductal adenocarcinomas were labeled for GATA3, it was absent in high-grade tumors that also lacked estrogen receptor protein. Favorable prognosis types of breast carcinoma (eg, mucinous carcinoma) and aggressive variants such as micropapillary carcinoma were equally

    Mammary analogue secretory carcinoma (MASC) has a specific ETV6-NTRK3 translocation and morphologically overlaps with acinic cell carcinoma (AciCC). Before the recognition of MASC, in AciCC, four histologic patterns were identified including microcystic, solid, papillary-cystic, and follicular. The aim of this study was to evaluate histologic patterns in these two neoplasms through comprehensive histologic subtyping. Using fluorescence in situ hybridization (FISH), we identified 14 cases of MASC and 21 cases of AciCC. We used comprehensive histologic subtyping to provide a semiquantitive assessment of histologic patterns in each tumor and performed immunohistochemical analyses including S100/vimentin/mammaglobin/DOG1. MASC often presented papillary-cystic patterns without a solid component, previously considered to be one of the four major patterns associated with AciCC. However, in our study, this histologic feature was rarely seen in AciCC and more characteristic of MASC. In aspiration cytology samples, MASC was associated with more cellular atypia. An immunohistochemical panel of S100/mammaglobin/DOG1 was found useful for differential diagnosis. Comprehensive subtyping of histologic patterns is a useful screening method prior to initiation of molecular testing.

    We investigated the expression of gross cystic disease fluid protein 15 (GCDFP) and mammaglobin (MGB) by immunohistochemical analysis in 71 invasive breast carcinomas (IBCs) subtyped into luminal (A and B), HER2, basal-like carcinoma (BLC), and unclassified triple-negative carcinoma (UTNC) by established surrogate immunohistochemical profiles. GCDFP and MGB were less likely to be expressed in BLC than in HER2 cancers (P = .000021 and P = .013, respectively) or luminal cancers (P = .00002 and P = .00008, respectively). However, the difference in GCDFP or MGB expression between HER2 and luminal cancers was not significant (P = 1.0 and P = .671, respectively). Our results suggest that luminal cancers demonstrate similar degrees of apocrine differentiation as HER2 cancers. Most BLCs and UTNCs are negative for MGB and GCDFP. Correlation with clinical findings may be needed to exclude the possibility of a metastasis to the breast when BLCs or UTNCs are encountered in a limited sample such as a core biopsy sample.

    The intimate histologic relationship of pregnancy-like hyperplasia (PLH) and cystic hypersecretory hyperplasia (CHH) has been previously reported. However, none of these published cases contained coexisting carcinoma. In this study, we describe 9 additional cases of this lesion, all of which also revealed ductal carcinoma in situ (DCIS) as well as invasive carcinoma in 1 case. Hematoxylin and eosin-stained slides were reviewed for all cases. All were women who ranged in age from 35 to 49 years (mean 42.0 years; median 42.5 years). Reasons for surgical biopsy were calcifications in 6, breast mass in 2, and nipple discharge in 1. One patient with a mass also experienced nipple discharge. Three women initially underwent needle core biopsy and 6 had an excisional biopsy. Six women ultimately had mastectomies. Histologically, 5 had CHH merging with coexisting PLH. Atypia was seen in one or both components. All 9 cases contained DCIS. Two cases showed micropapillary DCIS, one of which appeared to arise from atypical PLH, while 4 of the 7 cases containing cystic hypersecretory DCIS appeared to arise from coexisting atypical CHH. Well-differentiated invasive carcinoma was identified in 1 case adjacent to cystic hypersecretory DCIS. Subsequent sentinel lymph node biopsy in this case revealed micrometastatic disease. Clinical follow-up was obtained in 9 patients and ranged from 10 to 69 months. All patients were free of disease at the time of last follow-up. Careful clinical follow-up is recommended for lesions that display atypia in PLH, CHH, or a histologically combined lesion. If these lesions are found on a needle core biopsy specimen, an excisional biopsy is recommended. DCIS, usually micropapillary or cystic hypersecretory types, and rarely invasive carcinoma can arise in this setting. Affected patients are typically younger than those with more common types of breast carcinoma.

    Full Text Available ACC is a rare malignant tumor that affects most commonly the major and minor salivary glands and rarely the paranasal sinuses, lacrimal gland, larynx, ear, vulva, and so forth. The maxillary sinus when affected is considered having a poor prognosis due to delayed diagnosis and delayed treatment credited to its slow spread, late symptoms, and complex anatomy which hampers surgical resection. The expressions of tumor markers too have a significant role in determining the prognosis. The treatment of choice consists of wide radical resection of the tumor followed by radiotherapy. Rehabilitation options in cases with huge maxillary defects still need further exploration.

    Only few case reports of mucinous cystic pancreatic neoplasm containing an undifferentiated carcinoma with osteoclast-like giant cells have been described in the literature. In the majority of cases this unusual association of tumors seems related to a favorable outcome. We present the second case of an indeterminate mucin-producting cystic neoplasm containing an area of carcinoma with osteoclast-like giant cells. The specific features of the two histotypes and the rapid course of the disease make our clinical case remarkable. A 68 year old female came to our attention for a pancreatic macrocystic mass detected with ultrasonography. Her past medical history was silent. The patient reported upper abdominal discomfort for two months; nausea, vomiting or weight loss were not reported. Physical examination revealed a palpable mass in the epigastrium; scleral icterus was absent. Cross-sectional imaging showed a complex mass of the neck and body of the pancreas, characterized by multiple large cystic spaces separated by thick septa and an area of solid tissue located in the caudal portion of the lesion. The patient underwent total pancreatectomy with splenectomy. Pathological examination revealed a mucinous cystic neoplasm with a component of an undifferentiated carcinoma with osteoclast-like giant cells. Because of the absence of ovarian-type stroma, the lesion was classified as an indeterminate mucin-producing cystic neoplasm of the pancreas. The immunohistochemical studies evidenced no reactivity of osteclast-like giant cells to epithelial markers but showed a positive reactivity to histiocytic markers. Numerous pleomorphic giant cells with an immunohistochemical sarcomatoid profile were present in the undifferentiated carcinoma with osteoclast-like giant cells. A rapid tumor progression was observed: liver metastases were detected after 4 months. The patient received adjuvant chemotherapy (Gemcitabine) but expired 10 months after surgery. Our case confirms that the

    Full Text Available Background: Adenoid hypertrophy is one of the most common health problems affecting the paediatric population. This study aims to correlate adenoidal nasopharyngeal ratio (ANR with symptoms of enlarged adenoids in children with enlarged adenoids. Materials and Methods: It was a year, cross-sectional, hospital-based study conducted at Lautech Teaching Hospital, Osogbo. ANR was determined by dividing adenoidal depth with nasopharyngeal depth on the plain lateral radiographs. Results: A total of 90 consecutive children consisting of 61 males and 29 females were included in the study with M:F ratio of 2.1:1. Their ages ranged from 8 months to 11 years. All the patients presented with nasal obstruction, mouth breathing and noisy breathing. Majority (64.5% had severe obstructions with preponderance among children of 3-5 years (39.9%. Linear regression analysis showed significant association between age and ANR (t = 10.447, P < 0.001. There was high significant association (P < 0.05 between presenting symptoms and degree of nasopharyngeal airway obstruction; for snoring (r = 0.251, P = 0.000, sleep apnoea (r = 0.594, P = 0.000, nasal discharge (r = 0.314, P = 0.001, excessive daytime sleepiness (r = 0.219, P = 0.019 and failure to thrive (r = 0.240, P = 0.011. Conclusion: Lateral X-ray of the nasopharynx is an effective tool to evaluate children with suspected adenoid hypertrophy. It correlates well with patients′ symptoms and provides objective measures of adenoid hypertrophy.

    Full Text Available Malignant transformation of a mature cystic teratoma (MCT is an infrequent, often asymptomatic event. We report the first example of a struma ovarii with a focus of follicular variant of papillary thyroid carcinoma (a, mucinous adenocarcinoma (b, and strumal carcinoid tumor (c—all three arising in one mature cystic teratoma of the ovary. From our reviews, we found limited data to guide management when these malignant foci occur within an MCT. Consideration should be given to thyroidectomy followed by total-body scanning and serum studies for foci of thyroid carcinoma and adjuvant therapy with thyroidectomy and radioablation if residual disease is identified (a. Additionally, extrapolating from data for mucinous adenocarcinomas, consideration could be given to adjuvant chemotherapy after appropriate staging (b. Strumal carcinoid tumors should be treated as tumors of low malignant potential. Observation is appropriate if after complete staging, no invasive implants are noted (c.

  7. Comparative study of monoclonal antibody B72.3 and gross cystic disease fluid protein-15 as markers of apocrine carcinoma of the breast.

    Gross cystic disease fluid protein-15 (GCDFP-15) is a commonly used apocrine marker; however, its expression was recently found to decrease in infiltrating, larger, or metastasizing apocrine carcinomas of the breast. In the breast, monoclonal antibody (MAb) B72.3 has been reported to be useful as an apocrine marker although it is used for that purpose much less frequently than GCDFP-15. In the search for a more consistent apocrine marker, immunoreactivity for MAb B72.3 was examined in apocrine carcinomas at different stages and compared with GCDFP-15. 47 of 51 apocrine carcinomas (92%) and 9 of 62 ordinary carcinomas (15%) were MAb B72.3 positive, while 39 of 51 apocrine carcinomas (76%) and 13 of 62 ordinary carcinomas (21%) were GCDFP-15 positive. Thus, both sensitivity and specificity were higher for MAb B72.3. Furthermore, unlike GCDFP-15, MAb B72.3 exhibited positivity irrespective of infiltrating status, tumor size, or metastatic status. There was no correlation between MAb B72.3-immunoreactivity and GCDFP-15-expression. The combined usage of MAb B72.3 with GCDFP-15 was useful to confirm the diagnosis of apocrine carcinoma, especially for advanced tumors, with only two cases being negative for both MAb B72.3 and GCDFP-15. Whether these two cases should be differentiated from ordinary apocrine carcinomas remains to be investigated.

    Full Text Available Mature cystic teratomas (MCT, also known as dermoid cysts, are the most common ovarian germ cell tumors and the most common ovarian neoplasms in patients younger than 20 years. Malignant transformation (MT is a rare complication of MCTs which may occur in 1–2% of the cases. Squamous cell carcinoma (SCC is the most frequent histology arising from MCTs and its appearance depends on diverse risk factors such as patient's age, the size of the tumor and levels of serum tumor markers. Diagnosis and treatment constitute a big challenge due to the rarity and the aggressive course of this entity. Adjuvant chemotherapy has a leading role in the treatment of MCT-arising SCC, while the use of radiotherapy or chemoradiation is still under consideration. Herein, we report a case of a post-menopausal woman, presenting with mild symptoms and a large pelvic mass deriving from the left ovary occurring as dermoid cyst. Simultaneously, we review the literature stressing out the prognostic factors and the treatment options for MCT arising SCC according to traditional and new therapy-strategies.

    Immunohistochemical analysis of gross cystic disease fluid protein-15 (GCDFP-15) and mammaglobin (MGB) is frequently used in routine practice for assessment of metastases or regional recurrences of breast origin. Breast cancer is highly heterogeneous. Expression of these 2 markers in various breast cancer subtypes has not been well studied. In addition, the usefulness of these two markers in combination in detecting breast origin has not been explored. In this study, a large cohort of breast cancers was evaluated for GCDFP-15 and MGB expression, both individually and combined. Their expression was correlated with cancer subtypes, other biomarkers and clinicopathologic parameters. A higher sensitivity for MGB (42.3%) than GCDFP-15 (31.6%) in detecting cancers of breast origin was observed. Combining both increased the sensitivity further, both for primary tumor (53.0%) and for nodal metastases (69.0%). GCDFP-15 was associated significantly with a breast cancer profile of good prognosis tumors, including lower grade (P < .001), pN (P = .029) and Ki-67 (P < .001) as well as negative basal markers expression (P = .043, .009, and .049 for c-Kit, CK5/6 and epidermal growth factor receptor, respectively) and, thus, may not be sensitive for detection of poor prognosis tumors. MGB has the highest expression in HER2-overexpressing cancers (56.6%), and may be a potentially useful marker for this subtype. Nonetheless, both markers showed low expression in the basal like (BLBC) subtype (11.9% and 21.4% for GCDFP-15 and MGB respectively), therefore, the detection of BLBC remains problematic. Negative results need to be interpreted with caution, and correlation with other clinical findings may be required to exclude the possibility of metastatic BLBC. Copyright © 2013 Elsevier Inc.

    Transcription factor SRY-related HMG-box 10 (SOX10) is an important marker for melanocytic, schwannian, myoepithelial, and some salivary gland tumors. The aim of this study was to investigate SOX10 expression more thoroughly in the salivary gland neoplasms, including mammary analogue secretory carcinoma and hyalinizing clear cell carcinoma harboring specific genetic rearrangements. A new rabbit monoclonal anti-SOX10 antibody (clone EP268) was used to examine SOX10 expression in 14 different types of salivary gland tumors. We found that acinic cell carcinoma (AciCC), adenoid cystic carcinoma, mammary analogue secretory carcinoma (MASC), epithelial-myoepithelial carcinoma, low-grade salivary duct carcinoma, sialoblastoma, basal cell adenocarcinoma, basal cell adenoma, and pleomorphic adenoma were SOX10 positive. Salivary duct carcinoma, lymphoepithelial carcinoma, hyalinizing clear cell carcinoma, and oncocytoma were SOX10 negative. Earlier, mucoepidermoid carcinoma (MEC) was considered a SOX10-negative tumor. This study identified a subgroup of SOX10-positive MEC cases with characteristic polygonal epithelial cells, pale-to-eosinophilic cytoplasm, and colloid-like dense eosinophilic material. Our data show SOX10 expression can be observed in salivary gland tumors with either one of the 4 cell types: acinic cells, cuboidal ductal cells with low-grade cytologic features, basaloid cells, and myoepithelial cells. In this article we thoroughly evaluated SOX10 expression in salivary gland tumors. SOX10 is useful in the differential diagnosis between myoepithelial carcinoma with clear cell features and hyalinizing clear cell carcinoma. It can also be used to discriminate low-grade salivary duct carcinoma from high-grade ones. Pathologists should be cautious with the interpretation of SOX10 positivity in salivary gland tumors, and correlation with histologic feature is mandatory. Copyright © 2016 Elsevier Inc.

    Cystic hypersecretory carcinoma (CHC) is an uncommon variant of ductal carcinoma in situ characterized by, among other features, the presence of luminal secretion resembling thyroidal colloid. CHC is thought to behave in an indolent manner but has the potential to give rise to invasive carcinoma, which is often poorly differentiated. We studied the immunohistochemical, clinical, and morphologic features of 10 cases of CHC. All patients were women averaging 62.8 years in age (range, 47 to 79 y). The clinical/radiographic presentation was a mass (5/10), calcifications (3/10), bloody nipple discharge (1/10), and unknown (1/10). Microscopic size of CHC ranged from 0.2 to 2.7 cm (mean, 0.9 cm). Micropapillary growth was present in all cases. Nuclear grade was intermediate (5/10) or high (5/10). One case also showed microinvasive carcinoma. All cases arose in a background of cystic hypersecretory hyperplasia (CHH) and/or CHH with atypia. CHC was ER in 8/10 cases (ER+/PR+, 4/10; ER+/PR+, 4/10). Two cases were ER-/PR-, including the case with microinvasive carcinoma. All were HER2-. Androgen receptor was expressed in 3/10 (30%) cases. Myoepithelial stains p63, smooth muscle myosin, and CK5 showed circumferential staining in 9/10 (90%) cases, whereas 1 case was negative for p63, smooth muscle myosin, and CK5 in both CHC and adjacent CHH. Basal-like carcinoma markers EGFR, CK14, and CK5 were negative in all cases, with the exception of 1 case that was positive for EGFR. Four patients with follow-up information showed no evidence of disease (mean, 5.5 y). CHC is a distinct variant of ductal carcinoma in situ that arises in a background of CHH and is characterized by micropapillary growth, intermediate-grade to high-grade nuclei, and luminal colloid-like secretion. CHC is usually ER and HER2-. Negative or discontinuous reactivity with myoepithelial markers may be seen, despite its in situ nature. CHC usually behaves in a nonaggressive manner as was seen in our patients who

    Carbonic anhydrase VI (CA6) is present in serous acinar cells of human salivary glands. The aim of this study was to investigate the diagnostic utility of CA6 in differentiating acinic cell carcinoma (AciCC) from its morphological mimic mammary analogue secretory carcinoma (MASC) of the salivary gland. CA6 immunostaining was performed in 28 cases of AciCC and 14 cases of MASC. All cases of AciCC showed positive CA6 staining. The staining pattern correlated with the number of serous acinar cells in tumours. All MASCs stained negatively for CA6. The results were compared with those obtained with currently used markers, including DOG1, mammaglobin, S100, and vimentin. CA6 showed sensitivity and specificity as high as those of DOG1 in diagnosing AciCC. CA6 expression was focally observed in basal cell adenoma and in one case of cystadenocarcinoma (1/3), but not in other salivary gland tumours, including mucoepidermoid carcinoma, adenoid cystic carcinoma, salivary duct carcinoma, lymphoepithelial carcinoma, epithelial-myoepithelial carcinoma, and pleomorphic adenoma. CA6 is a specific marker for serous acinar cells of salivary glands and AciCC. CA6 has sensitivity and specificity equal to those of DOG1 in the differential diagnosis between AciCC and MASC. A combination of CA6 and DOG1 could be an ideal immunohistochemical panel for AciCC. © 2015 John Wiley & Sons Ltd.

    Information on the clinicopathologic characteristics of invasive carcinomas arising from mucinous cystic neoplasms (MCNs) is limited, because in many early studies they were lumped and analyzed together with noninvasive MCNs. Even more importantly, many of the largest prior studies did not require ovarian-type stroma (OTS) for diagnosis. We analyzed 178 MCNs, all strictly defined by the presence of OTS, 98% of which occurred in perimenopausal women (mean age, 47 y) and arose in the distal pancreas. Twenty-nine (16%) patients had associated invasive carcinoma, and all were female with a mean age of 53. Invasion was far more common in tumors with grossly visible intracystic papillary nodule formation ≥1.0 cm (79.3% vs. 8.7%, P=0.000) as well as in larger tumors (mean cyst size: 9.4 vs. 5.4 cm, P=0.006); only 4/29 (14%) invasive carcinomas occurred in tumors that were 37 U/L) was also more common in the invasive tumors (64% vs. 23%, P=0.011). Most invasive carcinomas (79%) were of tubular type, and the remainder (5 cases) were mostly undifferentiated carcinoma (2, with osteoclast-like giant cells), except for 1 with papillary features. Interestingly, there were no colloid carcinomas; 2 patients had nodal metastasis at the time of diagnosis, and both died of disease at 10 and 35 months, respectively. While noninvasive MCNs had an excellent prognosis (100% at 5 y), tumors with invasion often had an aggressive clinical course with 3- and 5-year survival rates of 44% and 26%, respectively (P=0.000). The pT2 (>2 cm) invasive tumors had a worse prognosis than pT1 (≤2 cm) tumors (P=0.000), albeit 3 patients with T1a (<0.5 cm) disease also died of disease. In conclusion, invasive carcinomas are seen in 16% of MCNs and are mostly of tubular (pancreatobiliary) type; colloid carcinoma is not seen in MCNs. Serum CA19-9 is often higher in invasive carcinomas, and invasion is typically seen in OTS-depleted areas with lower progesterone receptor expression. Invasion is not seen

    Apoptosis is a programmed cell death; it provides an important balance between lymphocytes in adenoid tissue. The aim of this study is to investigate the role of apoptosis in chronic adenoiditis and adenoid hypertrophy. This is the first study in the literature about apoptosis in adenoid hypertrophy and chronic adenoiditis. Prospective case-control study in a tertiary referral university hospital was conducted. 46 patients who had chronic adenoiditis and adenoid hypertrophy underwent adenoidectomy. Adenoids were evaluated for apoptosis and assembled into groups according to their size. Apoptotic cells were counted in three different microscopic fields and their average was taken for every microcompartment. As a result of immunohistochemical staining, specimens were compared for their apoptotic cell rate. The difference in apoptosis of chronic adenoiditis and adenoid hypertrophy groups is statistically significant (phypertrophy groups revealed significant differences for intrafollicular and intraepithelial areas, and insignificant differences for interfollicular and subepithelial areas. Although apoptosis could not totally explain the pathogenesis of chronic adenoiditis and adenoid hypertrophy, it appeared to play an important role in it. Apoptosis functions to limit adenoid hypertrophy. Adenoid apoptosis appears to be age-dependent. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Abstract Introduction There are increasing reports of bowel cancer in cystic fibrosis, suggesting a possible causal link. Individuals with cystic fibrosis who have advanced lung disease present a high operative risk, limiting curative treatment options in early bowel malignancy. Case presentation We describe a 41-year-old Caucasian woman with cystic fibrosis and severe lung disease who had been considered for lung transplantation, who presented with rectal bleeding and was found to have a Stage I adenocarcinoma of the sigmoid colon. After considerable discussion as to the operative risks, she underwent a laparoscopic resection and remains relatively well 1 year postoperatively with no recurrence. Conclusion We discuss the complexity of the management decisions for cystic fibrosis patients with severe lung disease and early stage colonic malignancy, particularly in the context of potential need for lung transplantation. The case demonstrates that cystic fibrosis patients with very severe lung function impairment may undergo laparoscopic abdominal surgical interventions without compromising postoperative airway clearance.

    Biofilms of pathogenic bacteria are present on the middle ear mucosa of children with chronic otitis media (COM) and may contribute to the persistence of pathogens and the recalcitrance of COM to antibiotic treatment. Controlled studies indicate that adenoidectomy is effective in the treatment of COM, suggesting that the adenoids may act as a reservoir for COM pathogens. To investigate the bacterial community in the adenoid, samples were obtained from 35 children undergoing adenoidectomy for chronic OM or obstructive sleep apnea. We used a novel, culture-independent molecular diagnostic methodology, followed by confocal microscopy, to investigate the in situ distribution and organization of pathogens in the adenoids to determine whether pathogenic bacteria exhibited criteria characteristic of biofilms. The Ibis T5000 Universal Biosensor System was used to interrogate the extent of the microbial diversity within adenoid biopsy specimens. Using a suite of 16 broad-range bacterial primers, we demonstrated that adenoids from both diagnostic groups were colonized with polymicrobial biofilms. Haemophilus influenzae was present in more adenoids from the COM group (P = 0.005), but there was no significant difference between the two patient groups for Streptococcus pneumoniae or Staphylococcus aureus. Fluorescence in situ hybridization, lectin binding, and the use of antibodies specific for host epithelial cells demonstrated that pathogens were aggregated, surrounded by a carbohydrate matrix, and localized on and within the epithelial cell surface, which is consistent with criteria for bacterial biofilms.

    To determine the rates of globe-sparing treatment and useful final visual function in patients with primary lacrimal sac/nasolacrimal duct carcinomas treated with multidisciplinary therapy. The medical records of 14 patients with primary lacrimal sac/nasolacrimal duct carcinoma treated at 1 institution were retrospectively reviewed. The patients were 9 men and 5 women; the median age at diagnosis was 58.5 years (range, 45-73 years). Seven patients presented with epiphora, 7 with a palpable mass in the inferomedial orbit, and 2 with dacryocystitis. In 3 patients, the diagnosis of cancer was not considered until during or after dacryocystorhinostomy. Seven patients had squamous cell carcinoma, 2 transitional cell carcinoma, 2 adenoid cystic carcinoma, and 1 each adenocarcinoma, poorly differentiated carcinoma, and inverted papilloma with carcinoma in situ transformation. Nine patients underwent surgical resection of the lacrimal sac and nasolacrimal duct and resection of the medial upper and lower eyelids, including canaliculi, partial ethmoidectomy, and medial maxillectomy. One patient underwent lacrimal sac biopsy only as another primary malignancy was discovered during the work-up for systemic disease. Four patients underwent orbital exenteration because of extensive involvement of the orbital soft tissue. Radiotherapy was recommended for 13 patients; in 1 patient, radiotherapy was not recommended because the patient had an inverted papilloma with carcinoma in situ transformation that was completely excised. The median radiation dose was 60 Gy. Eight patients received chemotherapy either concurrent with radiation therapy (5 patients), as neoadjuvant treatment (1 patient), or for progressive or metastatic disease (3 patients). The median follow-up time was 27 months (range, 6-96 months). In 10 patients, the globe was spared. In 9 of these 10 patients, visual acuity was the same as at baseline or better than 20/40 at last follow up. With multidisciplinary therapy

    Full Text Available Introduction: Malignant salivary gland tumors are rare entities. Despite advances in surgery, radiation therapy and chemotherapy, the rate of the mortality and five-year survival has not been improved markedly over the last few decades. The activation of EGFR- RAS-RAF signaling pathway contributes to the initiation and progression of many human cancers, promising a key pathway for therapeutic molecules. Thus, the objective of this study was to evaluate BRAF mutations in salivary gland carcinomas. Methods: We designed PCR- RFLP (Polymerase Chain Reaction -Restriction Fragment Length Polymorphism and screened 50 salivary gland carcinomas (SGCs including mucoepidermoid carcinoma (MEC, adenoid cystic carcinoma (AdCC and polymorphous low grade adenocarcinoma (PLGA for the BRAF V600E mutation. Results: PCR-RFLP analyses demonstrated no mutation in BRAF exon 15 for SGC samples at position V600, which is the most commonly mutated site for BRAF in human cancer. Conclusions: According to our results SGCs didn’t acquire BRAF mutations that result in a constitutive activation of the signaling cascade downstream of EGFR, hence SGCs can be a good candidate for anti EGFR therapies.

    To evaluate the prognostic significance of GATA-binding protein 3 (GATA-3), gross cystic disease fluid protein-15 (GCDFP-15) and mammaglobin (MGB) in invasive breast carcinomas (IBCs). GATA-3, GCDFP-15 and MGB were expressed in 37.9% (370/976), 26.0% (254/978) and 35.3% (348/986) of this cohort of 1017 IBCs, respectively. GCDFP-15 was an independent favourable prognostic factor in all cases [disease-free survival (DFS), hazard ratio (HR) 0.587, P = 0.049; overall survival (OS), HR 0.512, P = 0.049], as well as in oestrogen receptor (ER)-negative (DFS, HR 0.353, P = 0.012; OS, HR 0.310, P = 0.017) and HER2-positive (DFS, HR 0.279, P = 0.036; OS, HR 0.235, P = 0.050) cases; it also refined the prognostication of molecular apocrine cancers. GATA-3 and MGB did not show any prognostic significance. The commonly used breast carcinoma biomarkers vary in their prognostic implications. GCDFP-15 independently indicated a favourable prognosis, especially in ER-negative, HER2-positive and molecular apocrine cancers. GATA-3 and MGB were not associated with outcome. © 2014 John Wiley & Sons Ltd.

    Seventy patients with salivary gland carcinoma (63% major gland and 37% minor gland) are reviewed. Histologies included adenoid cystic (54%), mucoepidermoid (16%), and adenocarcinoma (14%). Patients were analyzed according to extent of surgery and whether or not adjuvant postoperative radiotherapy was given. There is no difference in survival in patients who had complete excision of gross tumor with or without adjuvant radiotherapy. Patients who did not undergo radiotherapy had a 62% actuarial risk of locoregional failure at 5 years, with a 20% risk in the adjuvantly irradiated group (P less than 0.001). A failure analysis demonstrates that among the 44% of patients with recurrence 71% (22/31) failed locoregionally and 69% (21/31) had distant metastases. Twenty-seven percent (19/70) died of disease, with 31% (6/19) dying of locoregional disease and 26% (5/19) of distant disease. Implications for management are discussed.

    Benign and malignant tumor cells can express altered adhesion properties, and these features can be associated with their proliferative and invasive characteristics. This study aimed to evaluate syndecan-1 and Ki-67 expression in ghost cell-containing odontogenic tumors. Clinical data were retrieved from laboratory records, and hematoxylin-eosin-stained slides and sections, labeled with monoclonal antibodies anti-syndecan-1 and anti-Ki-67 using the immunoperoxidase technique, were evaluated. Included were 21 central calcifying cystic odontogenic tumors (CCOTs) (4 associated with odontoma), 2 peripheral CCOTs, 1 dentinogenic ghost cell tumor, and 1 ghost cell odontogenic carcinoma (GCOC). Syndecan-1 was mainly expressed in cells resembling stellate reticulum and in stromal cells from the fibrous capsule. The mean Ki-67 labeling index was 4.1% (49.3% for GCOC), but it was not associated with syndecan-1 expression. Syndecan-1 is variably expressed in cells resembling the stellate reticulum, stromal cells, and basal cells and might be associated with the biology of these tumors. Copyright © 2014 Elsevier Inc.

    Full Text Available Abstract We report a rare male case of an undifferentiated carcinoma with osteoclast-like giant cells originating in an indeterminate mucin-producing cystic neoplasm of the pancreas. A 59-year-old Japanese man with diabetes visited our hospital, complaining of fullness in the upper abdomen. A laboratory analysis revealed anemia (Hemoglobin; 9.7 g/dl and elevated C-reactive protein (3.01 mg/dl. Carbohydrate antigen 19-9 was 274 U/ml and Carcinoembryonic antigen was 29.6 ng/ml. A computed tomography scan of the abdomen revealed a 14-cm cystic mass in the upper left quadrant of the abdomen that appeared to originate from the pancreatic tail. The patient underwent distal pancreatectomy/splenectomy/total gastrectomy/cholecystectomy. The mass consisted of a multilocular cystic lesion. Microscopically, the cyst was lined by cuboidal or columnar epithelium, including mucinous epithelium. Sarcomatous mononuclear cells and multinucleated osteoclast-like giant cells were found in the stroma. Ovarian-type stroma was not seen. We made a diagnosis of osteoclast-like giant cell tumor originating in an indeterminate mucin-producing cystic neoplasm of the pancreas. All surgical margins were negative, however, two peripancreatic lymph nodes were positive. The patient recovered uneventfully. Two months after the operation, multiple metastases occurred in the liver. He died 4 months after the operation.

    Adenoid is a kind of tonsil located in the posterior wall of nasopharynx. Enlargement of the adenoid can produce obstruction of the nasopharynx and Eustachian tube. Disturbance in discharge of nasal and paranasal secretions can be a cause of chronic rhinitis, sinusitis, and otitis media. Diagnosis of enlarged adenoid simply by inspection is different due to its location. Measurement of nasopharyngeal airway and adenoid using lateral radiographs of nasopharynx may be inaccurate for magnification and rotation. It was some limitations in demonstrating the actual state of nasopharyngeal airway and adenoid because it gives only two dimensional information. The authors measured the size and areas of nasopharyngeal airway and adenoid using MRI with sagittal and oblique coronal pilot views of T1 weighted spin echo. We categorized the patients into 4 groups according to the scoring system by symptoms such as apnea, mouth breathing, and snoring. The results of several measurment and their ratios were evaluated in these 4 categorized patients. The ratios of area of adenoid and nasopharyngeal airway (AA/Na) in each patient group were 6.52, 7.76, 10.53, 15.93, respectively. And the ratios of adenoid and nasopharyngeal airway (A/N) by Fujioka's method were 0.6, 0.65, 0.69, 0.71, respectively. We found that AA/Na might be the most effective index as an objective indicator in the evaluation of nasopharyngeal obstruction by the enlarged adenoid.

    Mammary analogue secretory carcinoma (MASC) of salivary glands is a newly recognized tumor entity. To explore a more practical and convenient immunohistochemical approach to distinguish MASC from other tumors arising from salivary glands as well as to expand the immunologic and genetic lineage of MASC, we examined 17 MASCs using clinicopathologic, immunohistochemical, and molecular analyses. Eighteen cases of acinic cell carcinoma, 18 cases of adenoid cystic carcinoma, 22 cases of mucoepidermoid carcinoma, and 14 cases of basal cell adenocarcinoma were brought in for comparison. Seventeen MASCs shared similar architectures with not only intraluminal or intracellular secretion but also low-grade vesicular nuclei. In addition, they were all immunoreactive for S-100 and SOX-10, whereas only 3 of 17 demonstrated reactivity for GATA-3 and P63, and 4 of 17 were focally positive for CD117. ETV6 translocation was detected in 10 cases by fluorescence in situ hybridization, whereas intact ETV6 was noted in 2 cases. Our data proposed a combined immunohistochemical panel to distinguish MASC from other tumors arising from salivary glands and expanded the immunologic and genetic lineage of MASC.

    Objective: To investigate the clinicopathological features of mammary analogue secretory carcinoma (MASC) of salivary glands, and its diagnosis, differential diagnosis, immunohistochemistry and molecular pathology. Methods: Seventeen cases of MASC were enrolled, with 9 cases of salivary acinar cell carcinoma and 18 cases of adenoid cystic carcinoma as control groups from Nanjing General Hospital from 1997 to 2014 were included in this retrospective study, combined with immunohistochemistry and molecular detection of ETV6-NTRK3 gene fusion. All cases were histologically reviewed with immunohistochemical staining (EnVision) for S-100 protein, SOX10, GATA3, CD117 expression in each group. Fluorescence in situ hybridization (FISH) was used to detect the ETV6-NTRK3 gene fusion. Results: The age of MASC patients ranged from 27 to 74 years with mean age of 47 and ratio of male and female was 4∶3. All cases showed infiltrative growth and diverse cytology and histology, including lobular (8 cases), cystic papillary (3 cases), cribriform mixed with papillary and glandular structures (6 cases) at various proportions. Some tumors of MASC also exhibited solid growth areas with occasional microcystic honeycombed pattern composed of small cysts merged into larger cysts resembling thyroid follicles. S-100 protein and SOX10 were strongly positive in all MASC cases (17/17). In addition, there was insignificant positivity for GATA3 (3/17) and CD117 (4/17). ETV6 gene fusion detection was informative in 12 MASC cases by FISH with 10 positive cases and 2 negative cases. Conclusions: Combined immunohistochemical positivity of S-100 protein, CD117 and SOX10 are useful in the diagnosis and differential diagnosis of MASC. FISH detection of ETV6-NTRK3 fusion offers an additional molecular diagnostic marker for the diagnosis.

    Full Text Available OBJECTIVE: this study aimed to evaluate the usefulness of current radiographic measurements, which were originally conceived to evaluate adenoid hypertrophy, as potential referral parameters. METHODS: children aged from 4 to 14 years, of both genders, who presented nasal obstruction complaints, were subjected to cavum radiography. Radiographic examinations (n = 120 were evaluated according to categorical and quantitative parameters, and data were compared to gold-standard videonasopharyngoscopic examination, regarding accuracy (sensitivity, negative predictive value, specificity, and positive predictive value. RESULTS: radiographic grading systems presented low sensitivity for the identification of patients with two-thirds choanal space obstruction. However, some of these parameters presented relatively high specificity rates when three-quarters adenoid obstruction was the threshold of interest. Amongst the quantitative variables, a mathematical model was found to be more suitable for identifying patients with more than two-thirds obstruction. CONCLUSION: this model was shown to be potentially useful as a screening tool to include patients with, at least, two-thirds adenoid obstruction. Moreover, one of the categorical parameters was demonstrated to be relatively more useful, as well as a potentially safer assessment tool to exclude patients with less than three-quarters obstruction, to be indicated for adenoidectomy.

    Primary squamous cell carcinoma of the breast (SCCB) is a rare disease, with a worldwide incidence breast cancer. If the cyst is large, the solid tumor shadow outside the cyst behind or around the cyst may be masked or hidden by the large cyst, which can sometimes yield an unclear view of the tumor shadow or make it impossible to visualize the shadow. In the present case, the contents within the cyst were completely aspirated and collected during the first step (FNA), thereby yielding a clearer, complete view of the solid tumor located outside the cyst. Thus, the subsequent step (CNB) was able to be performed in a more accurate and reliable manner. The combined use of FNA and CNB proved to be useful in making a preoperative diagnosis of SSCB accompanying a cyst. Copyright © 2017. Published by Elsevier Taiwan.

    The stroma in ovarian clear cell carcinoma often shows alternate mucoid and hyalinized change. The hyalinized stroma is recognized to be an aberrant deposition of basement membrane material produced by tumor cells. The mucoid stroma, however, has drawn far less attention, and its significance remains unclear. We examined 60 ovarian clear cell carcinomas for the distribution and nature of the mucoid stroma. For comparison, 125 other surface epithelial ovarian tumors were examined. Twenty-nine of 60 (48%) clear cell carcinomas showed a mucoid stroma, either focally (21 cases) or diffusely (8 cases). The mucoid stroma in clear cell carcinomas was distinct from that in other surface epithelial tumors as follows: it showed a compact spherule-like appearance, commonly occupying the cores of small papillae. It also exhibited a cribriform pattern, resembling that of adenoid cystic carcinoma. It was rarely associated with stromal cells, despite the presence of abundant glycosaminoglycan including hyaluronan. Alternatively, it was strongly associated with hyalinized stroma. Among 40 clear cell carcinomas that had at least one type of stroma, 26 (65%) had both, either concomitantly or separately. The mucoid stroma tended to attenuate if the hyalinized stroma developed. In vitro, a clear cell carcinoma cell line, HAC-2, formed a spherule-like structure containing hyaluronan in the center, and a significant amount of hyaluronan was detected by latex agglutination immunoturbidimetry, indicating that HAC-2 itself has the potential to produce hyaluronan. All of these facts indicate that the spherule-like mucoid stroma and hyalinized stroma represent different phases of the stromal remodeling process, which is promoted by the deposition of different extracellular matrices produced by clear cell carcinoma cells. The spherule-like mucoid stroma and hyalinized stroma are considered complementary diagnostic signatures of ovarian clear cell carcinoma.

    Full Text Available Primary squamous cell carcinoma of the breast (SCCB is a rare disease, with a worldwide incidence <0.1%. In many cases, it is clinically characterized by rapid growth. Cyst formation due to central necrosis of the tumor accompanies its growth of the tumor in approximately 60–80% of all cases. Furthermore, it is considered difficult to diagnose SCCB solely on the basis of findings from diagnostic imaging. For large intracystic tumors, mammotome biopsy or core needle biopsy (CNB is rarely performed. Instead, fine-needle aspiration (FNA targeted at the tumor inside the cyst is often performed. The accurate diagnosis rate of SCCB using FNA is lower than that for ordinary-type breast cancer. If the cyst is large, the solid tumor shadow outside the cyst behind or around the cyst may be masked or hidden by the large cyst, which can sometimes yield an unclear view of the tumor shadow or make it impossible to visualize the shadow. In the present case, the contents within the cyst were completely aspirated and collected during the first step (FNA, thereby yielding a clearer, complete view of the solid tumor located outside the cyst. Thus, the subsequent step (CNB was able to be performed in a more accurate and reliable manner.

    Lysozyme is an enzymatic marker of acinar and intercalated duct cells of normal salivary glands. The aim of this study was to verify whether lysozyme expression could be useful to distinguish acinic cell carcinoma (ACC) from its main mimic, mammary analog secretory carcinoma (MASC). For comparison, DOG1 expression was analyzed as well. Seventeen cases of ACC, 15 MASC, and 125 other salivary tumors were studied. Lysozyme expression was found in tumor cells as well as in secreted material of MASC (86.6 % of cases) and in ductal cells of epithelial-myoepithelial carcinoma (EMC-53.8 %), pleomorphic adenoma (PA-29.1 %) and polymorphous low-grade adenocarcinoma (PLGA-23.8 %). However, in ACC, lysozyme was not expressed. Three patterns of DOG1 staining were seen: apical-luminal, cytoplasmic, and mixed cytoplasmic/membranous. The apical-luminal pattern was detected in ductal cells of ACC (58.8 % of cases), EMC (38.4 %), adenoid-cystic carcinoma (AdCC-35.3 %), PA (8.3 %), and PLGA (4.8 %). These tumors also showed mixed membranous/cytoplasmic staining for DOG1. MASC, mucoepidermoid, and salivary duct carcinomas exhibited only DOG1 cytoplasmic staining. In conclusion, lysozyme cannot be used as a marker of acinar differentiation in salivary tumors. However, lysozyme expression can be helpful to distinguish MASC from ACC due to its high frequency in the former and absence in ACC. It is likely that in MASC, lysozyme expression may reflect a lactational-like secretory differentiation since lysozyme belongs to breast milk proteins. Regarding DOG1 expression, the apical-luminal pattern is related to acinar and intercalated duct differentiation whereas the cytoplasmic staining does not seem to be associated with a specific cellular phenotype.

  14. Primary small cell neuroendocrine carcinoma of the breast: The histogenetic diatribe

    Full Text Available The article entitled “Primary small cell neuroendocrine carcinoma of the breast: a report of two cases and review of the literature” by Spinelli et al. [1]. The authors stated that “the histogenesis is still unclear because the presence of neuroendocrine cells in normal breast has not been proved conclusively”. Moreover they reported two histogenetic hypotheses, the first one stating that “small cell neuroendocrine carcinoma (SCNC is a variant of metaplastic carcinoma arising from a lobular or ductal carcinoma”, the second one claiming that “it is a distinct type of breast carcinoma different from the usual type”. We appreciate this case report and we agree with the authors on the histogenetic diatribe of this rare type of breast neoplasia. In this background, we would highlight our previous case report about a solid variant of mammary adenoid cystic carcinoma merging with "small cell carcinoma" [2] in which we found positivity for CD10 and S100 and negativity for estrogen receptors, both in sbACC and in SCC, in keeping with a myoepithelial origin of both neoplastic areas [3] supporting the hypothesis that the “two components share the same histogenetic myoepithelial origin and represent an example of dedifferentiation along neuroendocrine phenotype lines occurring in a multipotential neoplastic stem line, already committed towards a myoepithelial phenotype”. These findings are in keeping with the first hypothesis about the metaplastic, divergent histogenetic nature of SNSC and we think that this rare SNSC, albeit arising from a different tumor, could be introduced in this case review of the literature, also for its contribute to the histogenetic diatribe.

    To investigate the behavior difference of allergic rhinitis with adenoid hypertrophy between study group and control group. One hundred and seventeen children diagnosed as allergic rhinitis with adenoid hypertrophy were enrolled in our study were divided into study group and control group. Forty-two children treated with local steroid nasal spray for two to three months and antihistamine were control group. Seventy-five children treated with endoscopic adenoidectomy and drug treatment were study group; All children' parents were inquired for their clinical presentation. No distinctive differences were found between the two groups (P > 0.05) in adenoid hypertrophy, accompanying nasal problems and clinical questionnaire scoring. Significant statistical distinction were found (P breathing, and recurrent respiratory tract infection between the two groups after three-month follow up. Endoscopic adenoidectomy should be taken into account for allergic rhinitis with adenoid hypertrophy in children. Adenoidectomy would be useful for the improvement of behavior symptoms.

    A tropism to epithelial cells and lymphocytes, an inhibition of apoptosis in host cells, an ability to occurrence in persistent form resistant to antibiotic treatment are the features of Chlamydia pneumoniae, which can have connection with chronic inflammation of an adenoid tissue and adenoid hypertrophy. This study aimed to (1) detect the C. pneumoniae in an adenoid in children undergoing adenoidectomy, (2) estimate a connection between C. pneumoniae occurrence and the size of adenoid, (3) demonstration in which of adenoid cells C. pneumoniae occurs most often. The examined group consisted of 200 children aged from 2 to 16 years (mean age 6,4) undergoing adenoidectomy. In all children during qualification for adenoidectomy a fiberoscopic examination of the nasopharynx was performed. A part of removed adenoid tissue was analysed by real-time PCR for C. pneumoniae. Adenoids from children with positive PCR examination and from 10 children with negative PCR examination were examined using immunohistochemistry (IHC). C. pneumoniae in the adenoid was present in 5,5% children. Positive results were obtained most frequently (24,14%, 7/29) in the eldest group (10-16 years). A statistical analysis demonstrated the correlation between C. pneumoniae occurrence in an adenoid tissue and the size of adenoid. In immunohistochemistry C. pneumoniae was found the most frequently in lymphocytes and in epithelial cells. A presence of C. pneumoniae in lymphocytes and epithelial cells of the adenoid first of all in older children with adenoid hypertrophy confirms the participation of this bacteria in adenoid pathology.

    Cystic partially differentiated nephroblastoma is a relatively rare tumour of the kidney usually affecting infants. Cystic Wilms' tumour and multilocular cystic nephroma should be distinguished from cystic partially differentiated nephroblastoma. Multilocular cystic nephroma is a benign tumour whereas cystic Wilms' tumour is at the malignant end of the range of classification of such tumours. Cystic partially differentiated nephroblastoma may undergo local recurrence but there is no report of metastasis.

    We illustrate the sonographic findings of malignant breast masses that can mimic a cystic component with pathologic correlations. The disease entities presented in this study include infiltrating ductal carcinoma, ductal carcinoma in situ (DCIS), papillary carcinoma, mucinous carcinoma, medullary carcinoma, metaplastic carcinoma, and a malignant phyllodes tumor. Malignant masses with a cystic component are often characterized by well-circumscribed round, oval, or lobular masses, thereby appearing benign on ultrasonography. On pathology, the cystic component of a malignant mass is identified by cystic degeneration, hemorrhage, necrosis, or ductal dilatation. If the mass is well-circumscribed with a cystic component, a biopsy should be considered in the analysis of the solid component within a mass.

    Between 1969 and 1985, 73 patients with maxillary sinus cancers underwent surgical excision and postoperative radiotherapy. The clinical stage distribution by the AJC system was 3T{sub 1}, 16T{sub 2}, 32T{sub 3} and 22 T{sub 4}. Six patients had palpable lymphadenopathy at diagnosis. Surgery for the primary tumor consisted of partial or radical maxillectomy, and if disease stage indicated it, ipsilateral orbital exenteration. This was followed by radiation treatment delivered through a wedge-pair or three-field technique. All but 3 patients received 50-60 Gy in 2 Gy fractions to an isodose line defining the target volume. Elective neck irradiation (ENI) was nor routinely given. Clinically involved nodes were treated with definitive radiotherapy (5 patients) or combined treatment (1 patient). Forty-five patients had no evidence of disease at the last follow-up. The 5-year relapse-free survival for the whole group was 51 percent. The overall local control rate was 78 percent, Patients with larger tumors, particularly if they also had histological signs of nerve invasion, had a higher recurrence rate than others. The overall nodal recurrence rate without ENI was 38 percent for squamous and undifferen-tiated carcinoma, and only 5 for adenoid cystic carcinomas. Therefore, the current recommendation is to deliver elective nodal irradiation routinely to patients with squamous or undifferentiated carcinoma, except for those who have T{sub 1} lesions. Treatment complications were vision impairment, brain and bone necrosis, trismus, hearing loss, and pituitary insufficiency. The incidence of major side effects was determined by disease extent and treatment technique. Many technical refinements were introduced in order to limit the dose to normal tissues in an attempt to reduce the complication rate. To what extent such practice influences the outcome will be determined from subsequent analysis. (author). 23 refs.; 2 figs.; 5 tabs.

    Purpose: To assess the outcomes, toxicity, and quality of life (QOL) of patients with primary parotid carcinoma treated with surgery and postoperative radiotherapy at the Daniel den Hoed Cancer Center. Methods and Materials: Between 1995 and 2010, 186 patients with parotid carcinoma were treated with parotidectomy with or without neck dissection, followed by radiotherapy. Elective nodal irradiation (ENI) was applied to high-risk, node-negative disease. End points were locoregional control (LRC), disease-free survival (DFS), cause-specific survival (CSS), and overall survival (OS), late toxicity, and QOL. Results: After a median follow-up of 58 months (range, 4-172 months), the 5-year Kaplan-Meier estimates for LRC, DFS, CSS, and OS were 89%, 83%, 80%, and 68%, respectively. Forty-five events were reported: 24 distant metastases (DM) and 21 locoregional failures (LRF). Event-free survival rates by histological types were 89%, 78%, 76%, 74%, and 70% for acinic cell, mucoepidermoid, adenoid cystic, adenocarcinoma, and squamous cell carcinoma, respectively. More LRF were reported in patients with squamous cell and high-grade mucoepidermoid carcinoma (21% and 19%, respectively) than in patients with other histological types (p = 0.04) and more DM in patients with adenoid cystic and adenocarcinoma (20% and 19%, respectively) than in patients with other types (p = 0.03). None of the high-risk node-negative patients who received ENI developed regional failure. On multivariate analysis, T stage, N stage, grade, and presence of perineural invasion and facial paralysis correlated significantly with DFS. The 5-year cumulative incidence of grade {>=}2 late toxicity was 8%. QOL scores deteriorate during and shortly after treatment but returned in almost all scales to baseline scores within 6 months. Conclusions: Of the entire group, surgery and postoperative radiotherapy resulted in excellent outcomes with minimal side effects and preservation of good QOL scores. However, in

    Radiograph of the nasopharynx is still the most commonly used imaging method to investigate the adenoidal tissue. Due to the variety and complexity of proposed methods to measure the adenoid size, some radiologists prefer subjective evaluation, which can, however, be imprecise and inaccurate. We review and describe several methods to determine the adenoid size, taking into account the practicity, accuracy and precision with the aim of pointing out the best methods to be applied in daily routine practice.

  4. The adenoid: Its history and a cautionary tale.

    2017-06-01

    The existence of the adenoid first appears to have been noted by Conrad Victor Schneider in 1661. James Yearsley reported in 1842 one case in which he improved hearing by removal of a mucus membrane from behind the uvula, which indicates some appreciation of a relationship of the nasopharynx to ear disease. Hans Wilhelm Meyer, in 1868, was the first to demonstrate the relationship of the adenoid to ear disease and to develop an effective, although somewhat difficult, surgical operation to remove the adenoid. Removal of the adenoid became rapidly accepted worldwide as a treatment for many morbidities, including otitis, speech problems, cognitive problems, and sleep apnea. Until the 1920s, adenoidectomy often was performed as a staged procedure and without general anesthesia. Early tools and techniques included use of the bare fingernail, a finger ring knife, a curette, and electrical desiccation. From the mid-1930s to the early 1960s, radiation therapy of the adenoid was in extensive use, both for children and in caring for army aviators and navy submarine crews during WWII. The effectiveness of surgical adenoidectomy for hearing loss led to a belief that radiation, which had been found to ablate lymphoid tissue, would be equally effective, and led to the wide-spread use of radiation. Ultimately, 500 thousand to 2.5 million children and adults were estimated to have been treated with radiation, and follow-up studies found increased risk for cancer. Furthermore, a follow-up study by Stacey R. Guild (1890-1966), published in 1950, on a very large sample of children who previously were reported to have had their hearing loss diminished through radiation, found that irradiation had produced no effect on high-tone loss. Thus, irradiation was both useless and harmful. Acceptance of authority, which can lurk within medical culture, led to the development of a tragically misguided management of adenoid disease.

    Conclusion: this model was shown to be potentially useful as a screening tool to include patients with, at least, two-thirds adenoid obstruction. Moreover, one of the categorical parameters was demonstrated to be relatively more useful, as well as a potentially safer assessment tool to exclude patients with less than three-quarters obstruction, to be indicated for adenoidectomy.

    Adenoid hypertrophy is a condition that presents itself as the chronic enlargement of adenoid tissues; it is frequently observed in the pediatric population. The Ugrp2 gene, a member of the secretoglobin superfamily, encodes a low-molecular weight protein that functions in the differentiation of upper airway epithelial cells. However, little is known about the association of Ugrp2 genetic variations with adenoid hypertrophy. The aim of this study is to investigate the association of single nucleotide polymorphisms in the Ugrp2 gene with adenoid hypertrophy and its related phenotypes. A total of 219 children, comprising 114 patients suffering from adenoid hypertrophy and 105 healthy patients without adenoid hypertrophy, were enrolled in this study. Genotypes of the Ugrp2 gene were determined by DNA sequencing. We identified four single nucleotide polymorphisms (IVS1-189G>A, IVS1-89T>G, c.201delC, and IVS2-15G>A) in the Ugrp2 gene. Our genotype analysis showed that the Ugrp2 (IVS1-89T>G) TG and (c.201delC) CdelC genotypes and their minor alleles were associated with a considerable increase in the risk of adenoid hypertrophy compared with the controls (p=0.012, p=0.009, p=0.013, and p=0.037, respectively). Furthermore, Ugrp2 (GTdelCG, GTdelCA) haplotypes were significantly associated with adenoid hypertrophy (four single nucleotide polymorphisms ordered from 5' to 3'; p=0.0001). Polymorfism-Polymorfism interaction analysis indicated a strong interaction between combined genotypes of the Ugrp2 gene contributing to adenoid hypertrophy, as well as an increased chance of its diagnosis (p<0.0001). In addition, diplotypes carrying the mutant Ugrp2 (c.201delC) allele were strongly associated with an increased risk of adenoid hypertrophy with asthma and adenoid hypertrophy with allergies (p=0.003 and p=0.0007, respectively). Some single nucleotide polymorphisms and their combinations in the Ugrp2 gene are associated with an increased risk of developing adenoid hypertrophy

    Purpose : A retrospective analysis for patients with oropharyngeal carcinoma who were treated with radiation was performed to assess the results of treatment and patterns of failure, and to identify the factors that might influence survival. Methods and Materials : From March 1985 through June 1993, 53 patients with oropharyngeal carcinoma were treated with either radiation therapy alone or combination of neoadjuvant chemotherapy and radiation therapy at the Department of Radiation Oncology, Kyungpook National University Hospital. Patients' ages ranged from 31 to 73 years with a median age of 54 years. There were 47 men and 6 women. Forty-two patients (79.2%) had squamous cell carcinoma, 10 patients (18.9%) had undifferentiated carcinoma and 1 patient (1.9%) had adenoid cystic carcinoma. There were 2 patients with stage I 12 patients with stage II, 12 patients with stage III and 27 patients with stage IV. According to the TNM classification, patients were distributed as follows: T1 7, T2 2, T3 10, T4 7, TX 1, and N0 17, N1 13, N2 21, N3 2. The primary tumor sites were tonsillar region in 36 patients (67.9%) base of the tongue in 12 patients (22.6%), and soft palate in 5 patients (9.4%). Twenty-five patients were treated with radiation therapy alone and twenty-eight patients were treated with one to three courses of chemotherapy followed by radiation therapy. Chemotherapeutic regimens used were either CF (cisplatin and 5-fluorouracil) or CVB (cisplatin, vincristine and bleomycin), Radiation therapy was delivered 180-200 cGy daily,five times a week using 6 MV X-ray with or without 8-10 MeV electron beams. A tumor dose ranged from 4500 cGy to 7740 cGy with a median dose of 7100 cGy. The follow-up time ranged from 4months to 99 months with a median of 21 months. Results : Thrity-seven patients (69.8%) achieved a CR (complete response) and PR (partial response) in 16 patients (30.2%) after radiation therapy. The overall survival rates were 47% at 2 years and 42% at

    Full Text Available Introduction. Adenoid and tonsil hypertrophy is widespread in the pediatric population, affecting primarily younger children,aged 3 to 6 years. in 1884, a German pathologist, von Waldeyer-hartz, first described clusters of lymphoid tissue in mucosa ofthe throat, which he named facial lymphatic ring, known today as Waldeyer’s tonsillar ring. Waldeyer’s ring plays a significantrole in the development of immune response by allowing the contact of the immune system with multiple antigens and thus,enabling the development of the specific immunological response. the main points of contact of the body with the externalenvironment are the mucous membranes of the digestive and respiratory systems. Waldeyer’s ring, being at the opening of bothsystems, has a particular role in the development of immune response, especially during the first years of life.Aim. the aim of the study was to analyze the symptoms presented by children hospitalized in the Clinic of pediatric otolaryngology of the medical University of Warsaw that had been qualified for the surgical removal of the adenoid and/or tonsils.Material and methods.

    Epstein-Barr virus (EBV) is associated with the pathogenesis of several diseases in both adults and children. However, there have been no reports on the prevalence and amount of EBV in the adenoids of adults; thus, it is important to investigate these in the adenoids and tonsils of adults and children. In this study, 67 patients who underwent tonsillectomy or adenotonsillectomy were included and divided into two groups: adults aged ≥ 16 years (n = 35) and children aged EBV DNA. EBV was detected in 26 (74%) adenoids and 25 (71%) tonsils among the adult group and was detected 21 (66%) adenoids and 20 (63%) tonsils in the child group. There was no significant difference in EBV DNA prevalence between the adenoids and tonsils for each group. However, there was a significant correlation between EBV DNA load in the adenoids and tonsils of the same individual in both groups (r = 0.579, P EBV infection is prevalent in the adenoids and tonsils in adults and children. These results indicate that EBV continuously reside in the nasopharyngeal region after primal infection and may develop several diseases. © 2016 Wiley Periodicals, Inc.

    Full Text Available INTRODUCTION: There is an ongoing debate about the existence and effects of Helicobacter pylori (Hp in adenotonsillar tissue. OBJECTIVE: A clinical study was conducted to assess the existence of Hp in the adenoid and/or adenotonsillar tissues, which were surgically excised due to chronic adenotonsillitis. METHODS: Phosphoglucosamine mutase gene for the detection of Hp and cytotoxin-associated gene as virulence gene were examined in 84 adenotonsillar tissues obtained from 64 patients and patients' serum by using polymerase chain reaction. RESULTS: Hp IgG was detected in 57 (89% patients' serum. A total of seven tissue samples from 64 patients (10.9% were found positive for Hp DNA, of which five were adenoids and two were tonsil tissues. All polymerase chain reaction positive samples were also positive for the cytotoxin-associated gene, which is a virulence determinant for the organism. CONCLUSION: This study suggests that children are exposed to Hp at an early age of their life in this province. Hp may have a role in the pathogenesis of chronic adenotonsillitis, especially in endemic areas.

  8. MYB Translocation Status in Salivary Gland Epithelial-Myoepithelial Carcinoma: Evaluation of Classic, Variant, and Hybrid Forms.

    2017-11-09

    Epithelial-myoepithelial carcinoma (EMC) is a malignant salivary gland neoplasm comprised of a biphasic arrangement of inner luminal ductal cells and outer myoepithelial cells. Adenoid cystic carcinoma (AdCC) is also a biphasic tumor comprised of ductal and myoepithelial cells, but these components tend to be arranged in a more cribriform pattern. The occurrence of "hybrid carcinomas" that show mixed patterns of EMC and AdCC raises questions about the relationship of these morphologically overlapping but clinically distinct tumors. AdCCs frequently harbor MYB-NFIB gene fusions. Mapping of EMCs (including hybrid forms with an AdCC component) for this fusion could help clarify the true nature of EMC as a distinct entity or simply as some variant form of AdCC. Twenty-nine cases of EMC were evaluated including 15 classic low-grade EMCs, 7 intermediate-grade EMCs, 2 EMCs with myoepithelial anaplasia, 1 EMC with high-grade transformation, and 4 hybrid EMCs with an AdCC component. Break apart fluorescence in situ hybridization for MYB was performed, as was MYB immunohistochemistry. For the hybrid carcinomas and those with high-grade transformation, the divergent tumor components were separately analyzed. A MYB translocation was identified in 5 of 28 (18%) tumors including 3 of 4 (75%) hybrid carcinomas and 2 of 7 (29%) intermediate-grade EMCs. For the positive hybrid carcinomas, the fusion was detected in both the EMC and AdCC components. The MYB fusion was not detected in any of the classic EMCs (0/15) or in any of the EMCs with myoepithelial anaplasia (0/2) or high-grade transformation (0/1). The fluorescence in situ hybridization assay was unsuccessful in 1 case. MYB immunostaining was seen in 5 of 5 fusion-positive cases, and also 9 of 23 fusion-negative tumors. Classic low-grade EMCs are genetically distinct from AdCCs in that they do not harbor MYB fusions. The presence of a MYB fusion in EMCs showing hybrid features of AdCC or exhibiting highly infiltrative growth

  9. Genetic variants in DNA double-strand break repair genes and risk of salivary gland carcinoma: a case-control study.

    Full Text Available DNA double strand break (DSB repair is the primary defense mechanism against ionizing radiation-induced DNA damage. Ionizing radiation is the only established risk factor for salivary gland carcinoma (SGC. We hypothesized that genetic variants in DSB repair genes contribute to individual variation in susceptibility to SGC. To test this hypothesis, we conducted a case-control study in which we analyzed 415 single nucleotide polymorphisms (SNPs in 45 DSB repair genes in 352 SGC cases and 598 controls. Multivariate logistic regression analysis was performed to calculate odds ratios (ORs and 95% confidence intervals (CIs. Rs3748522 in RAD52 and rs13180356 in XRCC4 were significantly associated with SGC after Bonferroni adjustment; ORs (95% CIs for the variant alleles of these SNPs were 1.71 (1.40-2.09, P = 1.70 × 10(-7 and 0.58 (0.45-0.74, P = 2.00 × 10(-5 respectively. The genetic effects were modulated by histological subtype. The association of RAD52-rs3748522 with SGC was strongest for mucoepidermoid carcinoma (OR = 2.21, 95% CI: 1.55-3.15, P = 1.25 × 10(-5, n = 74, and the association of XRCC4-rs13180356 with SGC was strongest for adenoid cystic carcinoma (OR = 0.60, 95% CI: 0.42-0.87, P = 6.91 × 10(-3, n = 123. Gene-level association analysis revealed one gene, PRKDC, with a marginally significant association with SGC risk in non-Hispanic whites. To our knowledge, this study is the first to comprehensively evaluate the genetic effect of DSB repair genes on SGC risk. Our results indicate that genetic variants in the DSB repair pathways contribute to inter-individual differences in susceptibility to SGC and show that the impact of genetic variants differs by histological subtype. Independent studies are warranted to confirm these findings.

    The aim of this study was to compare the cephalometric pattern of children with and without adenoid obstruction. The sample comprised 100 children aged between four and 14 years old, both males and females, subjected to cephalometric examination for sagittal and vertical skeletal analysis. The sample also underwent nasofiberendoscopic examination intended to objectively assess the degree of adenoid obstruction. The individuals presented tendencies towards vertical craniofacial growth, convex profile and mandibular retrusion. However, there were no differences between obstructive and non-obstructive patients concerning all cephalometric variables. Correlations between skeletal parameters and the percentage of adenoid obstruction were either low or not significant. Results suggest that specific craniofacial patterns, such as Class II and hyperdivergency, might not be associated with adenoid hypertrophy.

  11. ON THE ROLE OF BACTERIAL MICROFLORA IN ETIOLOGY OF CHRONIC ADENOIDITIS IN CHILDREN

    Directory of Open Access Journals (Sweden)

    D. A. Tulupov

    2014-01-01

    Full Text Available A review of the results of clinical studies on the role of pathogenic bacterial microflora in etiology of chronic adenoiditis in children is shown in this article. According to the literature data the main cause of the development of chronic diseases of the nasopharynx in children is viral infection. The role of the bacterial microflora is secondary, but nevertheless significant. The main bacterial pathogens isolated from the nasopharynx of children with chronic adenoiditis are Staphylococcus aureus, Haemophilus influenzae and Streptococcus pneumonia. However there is significant dissociation in the prevalence of these bacterial agents according to the data of different scientists. Ability of the bacteria to produce biomembranes plays significant role in formation of persistence of the above-mentioned pathogens in the nasopharynx in chronic adenoiditis. Bacterial biomembranes as well as the revealing of the large amounts of bacteria within the tissues of adenoids determines discussions on possibilities of systemic and topical antibacterial treatment.

    The aim of this study was to investigate the health-related quality of life (HRQOL) in 5-7-year-old children diagnosed with adenoid hypertrophy and the impact of adenoid hypertrophy on affected families. This is a cross-sectional case-control study evaluating 5-7-year-old children with adenoid hypertrophy (n=195), 5-7-year-old healthy children (n=156), and associated caregivers (parents and/or grandparents). A Chinese version of the PedsQL™ 4.0 Generic Core Scale was used to assess childhood HRQOL, and a Chinese version of the Family Impact Module (FIM) was used to assess the impact of adenoid hypertrophy on family members. HRQOL scores were compared between the children with adenoid hypertrophy and healthy children. In addition, a multiple step-wise regression with demographic variables of children and their caregivers, family economic status, and caregiver's HRQOL as independent variables were referenced to determine the factors that may influence HRQOL in children with adenoid hypertrophy. Children with adenoid hypertrophy showed significantly lower physical, emotional, social, and school functioning scores than healthy children (phypertrophy also scored significantly lower than caregivers for healthy children on physical, emotional, social, cognitive, and communication functioning (phypertrophy-affected children also exhibited significantly higher levels of worry than healthy children (phypertrophy (phypertrophy were associated with lower HRQOL in both children and their caregivers, and may negatively influence family functioning. In addition, caregivers' social characteristics may also significantly affect the HRQOL in children with adenoid hypertrophy. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Neonatal renal cystic diseases have a great impact on the morbidity and mortality of the affected neonates and infants. A good insight into the pathophysiology, diagnosis and treatment options of various neonatal renal cystic diseases aid in early diagnosis and intervention, thereby preventing complications. PubMed search was done for articles on "neonatal renal cystic diseases" and relevant publications including reviews were considered for our article. Both hereditary and nonhereditary causes of cystic kidney diseases can result in severe morbidity and mortality. The main diagnostic modality is ultrasound imaging and most of the neonatal renal cystic diseases are detected during prenatal ultrasound screening. Commonly encountered neonatal renal cystic diseases are autosomal dominant polycystic kidney disease, autosomal recessive polycystic kidney disease and multicystic dysplastic kidney. A thorough knowledge of various renal cystic diseases can be of extreme prognostic value. Physicians should be aware of the impact of early diagnosis and intervention on the lives of those affected. Further research about treatment of these diseases is ongoing and can result in breakthrough therapies for these patients.

    The main aim of this study was to evaluate TIMP-1 expression in germinal centers of hypertrophied adenoids in children on the assumption that it can be treated as a marker of adenoidal tissue function. The study involved 54 children undergoing adenoidectomy; divided into three age groups: aged up to 5 years (8 children), 5-10 years (31 children) and over 10 years (15 children). The analyzed material was adenoids removed on the ground of hypertrophy, which caused obstructive symptoms and/or otitis media with effusion onset. Immunohistochemical analyses were carried out using monoclonal mouse antibody (Ab) (Novocastra) directed against human TIMP-1 protein. The presence of TIMP-1 positive lymphocytes within germinal centers and TIMP-1 immunostaining were scored. The immunohistochemical staining showed the TIMP-1 positive lymphocytes mainly within the mantle zone. There was no statistically significant difference between the mean age of children for TIMP-1 immunoreaction levels. We have not found statistical correlation between the TIMP-1 staining and the clinical status of patients. It is difficult to interpret our results. Our findings did not demonstrate changes in TIMP-1 expression according to age. This may indicate that the processes of hyperplasia, hypertrophy and atrophy of adenoid are not influenced by age and support our thesis that adenoid involution is rather the effect of changes in the number of lymphoid follicles that changes in them. However there is a need for further observational studies of TIMPs and MMPs in adenoid tissue. Copyright © 2013. Published by Elsevier Ireland Ltd.

    A 64-year-old woman presented with a 6-month history of exophthalmus of her right eye. She had no neurological deficit except for the exophthalmus and numbness in the right side of her forehead (frontal nerve territory). Neuro-imaging demonstrated a cystic mass in the right orbit. The tumour was totally removed by microsurgical transcranial surgery. The histological diagnosis was neurinoma. The origin of the tumour was considered to be the frontal nerve. Only two other cases of orbital cystic neurinoma have been reported. This rare clinical entity should be included in the differential diagnosis of a cystic mass in the orbit.

    The past two decades have witnessed recognition of several new types of renal cell carcinoma, each with distinct cytogenetic abnormalities. Included are several genetic and acquired cystic kidney diseases associated with development of renal cell carcinoma, the topic of this review. The risk in patients with autosomal dominant polycystic kidney disease is not accurately known but may be slightly increased. The risk for patients with von Hippel-Lindau disease is substantial, and death from renal cancer is common. For patients with tuberous sclerosis complex, the challenge is recognition of the occasional malignancy arising in a field of many benign tumors. Patients with end-stage kidney disease and acquired cystic kidney disease may develop a variety of renal cell carcinoma types. Progress in understanding the molecular basis of renal cyst formation and neoplastic disease has fostered development of targeted therapies that now hold promise for a group of neoplasms whose cure was traditionally dependent on surgical approaches.

    Although most specialists in otorhinolaryngology and pediatrics find halitosis to be a common problem in children with adenoid hypertrophy, there are no objective data on this topic in the literature. Whether adenoid hypertrophy is a risk factor for halitosis or whether halitosis is a sign of adenoid hypertrophy remains unclear. Thus, the aim of this study was to investigate whether children diagnosed with adenoid hypertrophy have a higher probability of halitosis than do children in the normal population and whether adenoidectomy can decrease oral malodor. Forty children with adenoid hypertrophy and 40 healthy subjects aged 5-15 years were included in the study. The children with adenoid hypertrophy underwent adenoidectomy operations and were followed for 3 months. We measured volatile sulfur compounds (VSCs), hydrogen sulfide (H2S), methyl mercaptan (CH3SH), and dimethyl sulfide (CH3)2S using an objective method, a portable gas chromatograph (OralChroma; AbiMedical, Osaka, Japan). The mean CH3SH and (CH3)2S levels were significantly different (p halitosis and adenoid hypertrophy, and a significant improvement in halitosis was obtained following adenoidectomy. The present study provides an association between halitosis and adenoid hypertrophy. If there is no other oral pathology causing halitosis, halitosis can be a sign of adenoid hypertrophy in children.

    We present the case of a child with chronic adenoiditis caused by a PspK+ NESp. We tested the pneumococcal isolate, designated C144.66, for antimicrobial resistance, the presence of the pspK gene and the expression of PspK. Sequence typing and genome sequencing were performed. C144.66 was found to be resistant to erythromycin and displayed intermediate resistance to penicillin and trimethoprim/sulfamethoxazole. C144.66 has the pspK gene in place of the capsule locus. Additionally, PspK expression was confirmed by flow cytometry. NESp are a growing concern as an emerging human pathogen, as current pneumococcal vaccines do not confer immunity against them. An inability to vaccinate against NESp may result in increased carriage and associated pathology.

    Full Text Available Background: Mesenchymal stromal cells (MSCs are multipotent progenitor cells that originally derived from bone marrow. Clinical use of bone marrow-derived MSC is difficult due to morbidity and low MSC abundance and isolation efficiency. Recently, MSCs have been isolated from various adult tissues. Here we report the isolation of adenoid tissue-derived MSCs (A-MSCs and their characteristics. Methods: We compared the surface markers, morphologies, and differentiation and proliferation capacities of previously established tonsil-derived MSCs (T-MSCs and bone marrow-derived MSCs (BM-MSCs with cells isolated from adenoid tissue. The immunophenotype of A-MSCs was investigated upon interferon (IFN-γ stimulation. Results: A-MSCs, T-MSCs, and BM-MSCs showed negative CD45, CD31 HLA-DR, CD34, CD14, CD19 and positive CD 90, CD44, CD73, CD105 expression. A-MSCs were fibroblast-like, spindle-shaped non-adherent cells, similar to T-MSCs and BM-MSCs. Adipogenesis was observed in A-MSCs by the formation of lipid droplets after Oil Red O staining. Osteogenesis was observed by the formation of the matrix mineralization in Alizarin Red staining. Chondrogenesis was observed by the accumulation of sulfated glycosaminoglycan-rich matrix in collagen type II staining. These data were similar to those of T-MSCs and BM-MSCs. Expression of marker genes (i.e., adipogenesis; lipoprotein lipase, proliferator-activator receptor-gamma, osteogenesis; osteocalcin, alkaline phasphatase, chondrogenesis; aggrecan, collagen type II α1 in A-MSCs were not different from those in T-MSCs and BM-MSCs. Conclusions: A-MSCs possess the characteristics of MSCs in terms of morphology, multipotent differentiation capacity, cell surface markers, and immunogeneity. Therefore, A-MSCs fulfill the definition of MSCs and represent an alternate source of MSCs.

    Full Text Available Background and Aim: Adenoids are normally large in children and their size starts to reduce during adolescence. Hypertrophic adenoids could be associated with allergic reactions. Enlarged adenoids result in nasal breathing difficulties and the child is forced to switch to mouth breathing. Airway obstruction causes postural alterations of jaw, tongue and head, and due to persistent obstruction, patient’s appearance changes to adenoid face. Evaluation of nasopharyngeal space in lateral cephalometic view is a simple and repeatable method for determination of the size and shape of adenoids and nasopharyngeal space which can provide a simple measurement of nasopharyngeal obstruction. The roof of nasopharyngeal space is covered by the sphenoid bone. Thus changes of nasorespiratory resistance by hypertrophic adenoids may affect the cranial base angles. In this study, the relationship between adenoid hypertrophy and cranial base angles was investigated. Materials and Methods: In this descriptive-analytic study, lateral cephalometric views of 7 to 14 y/o patients from the files of orthodontic centers in Rasht city were selected. The radiographs with proper resolution were separated for this research. Adenoid to nasorespiratory ratio (A/N Ratio was determined by Fujioka method and categorized in three groups: A (A/N 0.8, B (0.5adenoid hypertrophy (A and B groups was observed in 66% of cases whereas 34% were normal.

    To evaluate the presence of viruses and bacteria in middle ear and adenoids of patients with and without otitis media with effusion (OME). Adenoid samples and middle ear washes (MEW) were obtained from children with OME associated with adenoid hypertrophy undergoing adenoidectomy and tympanostomy, and compared to those obtained from patients undergoing cochlear implant surgery, as a control group. Specific DNA or RNA of 9 respiratory viruses (rhinovirus, influenza virus, picornavirus, syncytial respiratory virus, metapneumovirus, coronavirus, enterovirus, adenovirus and bocavirus) and 5 bacteria (S. pneumoniae, H. influenzae, M. catarrhalis, P. aeruginosa and S. aureus) were extracted and quantified by real-time PCR. 37 OME and 14 cochlear implant children were included in the study. At the adenoid, virus and bacteria were similarly detected in both OME and control patients. At the middle ear washes, however, a higher prevalence of bacteria was observed in patients with OME (p = 0.01). S. pneumoniae (p = 0.01) and M. catarrhalis (p = 0.022) were the bacteria responsible for this difference. Although total virus detection was not statistically different from controls at the middle ear washes (p = 0.065), adenovirus was detected in higher proportions in adenoid samples of OME patients than controls (p = 0.019). Despite both OME and control patients presented similar rates of viruses and bacteria at the adenoid, children with OME presented higher prevalence of S. pneumonia, M. catarrhalis in middle ear and adenovirus in adenoids when compared to controls. These findings could suggest that these pathogens could contribute to the fluid persistence in the middle ear.

    Purpose: To assess the role of Gamma Knife radiosurgery (GKRS) in the treatment of nonsurgical cystic brain metastasis, and to determine predictors of response to GKRS. Methods: We reviewed a prospectively maintained database of brain metastases patients treated at our institution between 2006 and 2010. All lesions with a cystic component were identified, and volumetric analysis was done to measure percentage of cystic volume on day of treatment and consecutive follow-up MRI scans. Clinical, radiologic, and dosimetry parameters were reviewed to establish the overall response of cystic metastases to GKRS as well as identify potential predictive factors of response. Results: A total of 111 lesions in 73 patients were analyzed; 57% of lesions received prior whole-brain radiation therapy (WBRT). Lung carcinoma was the primary cancer in 51% of patients, 10% breast, 10% colorectal, 4% melanoma, and 26% other. Fifty-seven percent of the patients were recursive partitioning analysis class 1, the remainder class 2. Mean target volume was 3.3 mL (range, 0.1-23 mL). Median prescription dose was 21 Gy (range, 15-24 Gy). Local control rates were 91%, 63%, and 37% at 6, 12, and 18 months, respectively. Local control was improved in lung primary and worse in patients with prior WBRT (univariate). Only lung primary predicted local control in multivariate analysis, whereas age and tumor volume did not. Lesions with a large cystic component did not show a poorer response compared with those with a small cystic component. Conclusions: This study supports the use of GKRS in the management of nonsurgical cystic metastases, despite a traditionally perceived poorer response. Our local control rates are comparable to a matched cohort of noncystic brain metastases, and therefore the presence of a large cystic component should not deter the use of GKRS. Predictors of response included tumor subtype. Prior WBRT decreased effectiveness of SRS for local control rates.

    2017-07-01

    Full Text Available Cystic nephroma is a rare, benign multicystic lesion of the kidney. This tumor occurs both in children and in adults. In children, it is highly prevalent in males; in adults, it is more frequent in women. The term “cystic nephroma” represents two apparently different entities: pediatric cystic nephroma, a benign form thought to originate from metanephric tissue, and adult cystic nephroma, considered as a lesion of mixed epithelial stromal tumor. The clinical presentation may be a palpable mass or nonspecific symptoms such as abdominal pain, hematuria, and urinary tract infections. In this review, we summarize the ultrasound imaging features of cystic nephroma and describe the characteristics of the most common renal cystic lesions and the differential diagnosis of cystic nephroma with other renal cystic lesions.

    Full Text Available Introduction: One of the major causes of pediatric morbidity today at the community level is infection involving the ear, nose, and throat. Maximum of these patients respond well initially on general regular medications, but then recurrent complaints are not very uncommon. One of the major causes for such recurrence is hypertrophy of adenoids, the evaluation of which requires a battery of sophisticated investigative tools and expertise which are lacking at the community level. The aim of the study is to evaluate various symptoms related to adenoid hypertrophy and its correlation to the size of the adenoid seen in the lateral view nasopharyngeal X-ray. The aim of the study was to assess various symptoms related to adenoid hypertrophy and its correlation with the size of adenoid radiologically. Methods: A total of fifty cases of pediatric age with strong clinical suspicion of adenoid hypertrophy were included in the study. Through ENT examination was done. X-ray lateral view nasopharynx was obtained. Results: Adenoid hypertrophy was graded according to symptoms score and lateral cephalometric/radiographs. Snoring was the most frequent symptom which had a linear relation with the size of the adenoid. Conclusion: There was good agreement between symptom and the X-ray findings.

    Multiple cystic lung disease represents a diverse group of uncommon disorders that can present a diagnostic challenge due to the increasing number of diseases associated with this presentation. High-resolution computed tomography of the chest helps to define the morphological aspects and distribution of lung cysts, as well as associated findings. The combination of appearance upon imaging and clinical features, together with extrapulmonary manifestations, when present, permits confident and accurate diagnosis of the majority of these diseases without recourse to open-lung biopsy. The main diseases in this group that are discussed in this review are lymphangioleiomyomatosis, pulmonary Langerhans cell histiocytosis and folliculin gene-associated syndrome (Birt-Hogg-Dubé); other rare causes of cystic lung disease, including cystic metastasis of sarcoma, are also discussed. Disease progression is unpredictable, and understanding of the complications of cystic lung disease and their appearance during evolution of the disease are essential for management. Correlation of disease evolution and clinical context with chest imaging findings provides important clues for defining the underlying nature of cystic lung disease, and guides diagnostic evaluation and management.

    Twenty-six children with obstructive sleep apnea were evaluated by lateral neck radiographs during wakefulness, and by polygraphic monitoring and upper airway fluoreoscopy during natural sleep. Children with craniofacial abnormalities, palatal surgery, and central nervous system disease were excluded from the study. Moderate or marked enlargement of tonsils and adenoids was noted on lateral neck radiographs of 18 of 26 patients. An objective measure of adenoidal enlargement, the adenoidal-nasopharyngeal ratio, correlated well with subjective judgment of adenoidal size but was not generally more useful than subjective estimation. Upper airway fluroescopy demonstrated the site and mechanism of obstruction in all patients. Because all children with moderate to marked adenotonsillar enlargement demonstrated obstruction at the adenoidal or tonsillar level on fluoroscopy, we now screen children with suspected sleep apnea with lateral airway radiographs and polysomnography. Fluoroscopy is reserved for children with mild adenotosillar enlargement, craniofacial dysplasia, prior cleft palate repair, or neuromuscular disorders. These results suggest that the pathogenesis of obstuctive sleep apnea in children involve anatomic factors which narrow the upper airway, sleep-related hypotonia of pharyngeal dilator musculature, and compensatory mechanisms to prevent or alleviate asphyxia.

    Full Text Available Lymphangioma of the pancreas is a rare benign tumor of lymphatic origin. Retroperitoneal lymphangiomas account for 1% of all lymphangiomas. Herein, we report a case of cystic pancreatic lymphangioma diagnosed in 34 year-old female patient who was hospitalized for a slight pain in the epigastrium and vomiting. Radiological imaging revealed a large multiloculated cystic abdominal mass with enhancing septations involving the upper retroperitoneum. During the laparoscopic surgery, a well circumscribed polycystic tumor was completely excised preserving the pancreatic duct. The patient made a complete recovery and is disease-free 12 months postoperatively.

    A malignant transformation or a tumor rupture is a rare complication of ovarian mature cystic teratoma (MCT). A tumor rupture in a malignant-transformed MCT has never been reported in the literature. We present the CT images of a 39-year old woman showing a large, predominantly cystic mass in the lower abdomen, with fat-fluid-level ascites. A contrast-enhanced solid component, with regional discontinuity within the cystic lesion, is also demonstrated. The pathologic diagnosis of the ruptured MCT unveils the malignant transformation (squamous cell carcinoma) and mesenteric carcinomatosis.

    To compare the digital, mirror and nasendoscopic assessment of adenoid size and posterior choanal obstruction in patients undergoing adenoidectomy. Prospective, blinded study. Otorhinolaryngology department at a London teaching hospital. Twenty-eight consecutive patients undergoing adenoidectomy in conjunction with tonsillectomy or myringotomy under general anaesthesia, aged 17 months to 16 years. Adenoid size and postnasal space obstruction as assessed by digital examination, nasendoscopy and trans-oral mirror visualization. These examination methods were each compared with each other. Nasendoscopy and mirror examination correlated well (Spearman's R(S) = 0.71, P palpation (R(S) = 0.26, P = 0.17) and only a moderate correlation between mirror examination and palpation (R(S) = 0.46, P = 0.014). If nasendoscopy is considered the gold standard, then palpation is a poor measure of adenoid hypertrophy and mirror examination consistently underestimates choanal occlusion.

    Diffuse cystic and nodular lung diseases have characteristic imaging findings. The most common causes of cystic lung disease are lymphangioleiomyomatosis and Langerhans cell histiocytosis. Other less common cystic lung diseases include Birt-Hogg-Dube syndrome, lymphocytic interstitial pneumonitis, and light chain deposition disease. Computed tomography is used to differentiate cystic lung disease from emphysema, honeycombing, cavities, and bronchiectasis, which mimic cystic lung disease. Diffuse nodular lung disease are categorized as centrilobular, perilymphatic, and random types. In diffuse nodular lung disease, a specific diagnosis is achieved through a combination of history, physical examination, and imaging findings. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Adenoid ameloblastoma with dentinoid is a rare odontogenic tumor. Granular cell ameloblastoma also is a less common histological subtype of ameloblastoma. In this report, the patient was a 31-year-old male. The lesion was located in the right mandible and was unicystic with well-defined borders. The tumor tissue was showing a combination of follicular, plexiform, and desmoplastic patterns of ameloblastoma with wide areas of granular cells, fibrous stroma, glandular pattern, and dentinoid calcified. Very few cases of distinct forms of ameloblastoma that show the formation of dentinoid has been reported. However, there are no cases of adenoid granular cell ameloblastoma with dentinoid reported.

    Cystic neoplasms of the liver are divided into two types: mucinous cystic neoplasm and cystic intraductal papillary neoplasm of the bile duct. We herein report two cases of cystic and papillary neoplasm of the liver which differed from the abovementioned types. Case  1. A 70-year-old man. Radiologically, a cystic tumor measuring 20 mm in diameter was found at the hepatic hilum. Right hepatectomy was performed under a diagnosis of intrahepatic cholangiocarcinoma (iCCA) based on the imaging findings. Case  2. A 70-year-old man. Radiologically, a cystic tumor measuring 60 mm in diameter was found at the hepatic hilum. Under a diagnosis of iCCA, left hepatic trisectionectomy was performed. In both cases, endoscopic retrograde cholangiography did not demonstrate communication between the cystic tumor and adjacent bile ducts. Pathologically, these two tumors were cystic neoplasms located at the hepatic hilum and were morphologically characterized by an intracystic papillary neoplasm composed of diffuse high-grade dysplasia and associated with an invasive carcinoma. Ovarian-like stroma was not found in the capsule of these tumors. Interestingly, there were peribiliary glands near these tumors, and MUC6 was expressed in these papillary neoplasms as well as in the peribiliary glands. These neoplasms might have arisen from the peribiliary glands. PMID:27656307

    Lactobacillus rhamnosus GG (L.GG) was present in all adenoids of children receiving the L. GG product. However, since L.GG was also found from the placebo group, one cannot confirm its effect on the occurrence of rhinovirus (RV) or enterovirus (EV). The present study was conducted to determine whether a 3-week oral consumption of L.GG would lead to presence of the probiotic in adenoid tissue. Furthermore, nasopharyngeal RV and EV findings and symptom data were investigated. The tissue samples were collected from 40 children aged 1-5 years about to undergo adenotomy due to recurrent acute/secretory otitis media, chronic rhinitis, or recurrent sinusitis after a 3-week daily consumption of L.GG (n = 20) or placebo (n = 20). Strain-specific real-time PCR was used to detect RV, EV, and L.GG in adenoid tissue. L.GG was recovered in the adenoid sample in 100% of children in the L.GG group and in 76% in the placebo group (p = 0.07). Both RV and EV were found in 31% of children in the L.GG group and in 18% of children in the placebo group (p = 0.67). The majority of the positive samples were positive for both RV and EV. Study diaries showed no differences in symptoms between the groups.

    During the last few decades, improved treatment measures and nutritional support in cystic fibrosis have increased survival and quality of life in these patients. There is a clear relationship between the development of malnutrition and worsening in respiratory function and both factors have been related to poor disease outcome. Malnutrition is a very frequent complication of this disease and is found in 20% of patients, due to negative energy-proteic balance. This disequilibrium can be explained by increased energy expenditure, high nutritional requirements and decreased oral intake. Periodic monitoring of clinical, anthropometrical and functional nutritional status is mandatory. Intake must be greater than requirements and specific nutritional support should be established when required. Patients with cystic fibrosis must receive a hypercaloric and hyperproteotic diet, with a high fat content, a normal quantity of carbohydrates and with pancreatic and liposoluble vitamin supplements in case of pancreatic insufficiency.

    Acquired cystic kidney disease (ACKD), also known as acquired renal cystic disease (ARCD,) occurs in patients who are on dialysis for end-stage renal disease. It is generally accepted that ACKD develops as a consequence of sustained uremia and can first manifest even before dialysis is initiated while the patient is still in chronic renal failure. The role of immune suppression, particularly in transplant recipients, in the development of ACKD, is still under investigation. The prevalence of ACKD is directly related to the duration of dialysis and the risk of cancer is directly related to the presence of cysts. Herein we review the current understanding of the pathophysiology and imaging implications of ACKD. (orig.)

The cystic hygroma of the mediastinum is a benign tumor and very infrequent, representing only 0.7 to 4.5% of all mediastinal tumors, and of these, only 1% is exclusively mediastinal in location. The definitive diagnosis is only possible by pathological examination, and the recommended treatment consists of complete surgical resection. Cases are described in isolated reports or series with few patients, and their readiness or synchronicity with other tumors, unknown, and to the best of out knowledge, not reported yet.

Children underwent adenoid vegetations, nasal speech, conductive hearing loss, ventilation disturbance in Eustachian tube. In all children adenoidectomy was indicated.38 boys and 30 girls at the age of 3-17 were divided in two main groups: * 29 children without hypertrophic (enlarged adenoids, * 39 children with enlarged (hypertrophic adenoids.The surgical treatment included insertion of ventilation tubes and adenoidectomy where there where hypertrophic adenoids.Clinical material was analyzed according to hearing threshold, hearing level, middle ear condition estimated by pure tone audiometry and tympanometry before and after treatment. Data concerning both groups were compared.The results indicated that adenoidectomy combined with the ventilation tubes facilitates secretory otitis media heeling as well as decrease of hearing impairments. That enables prompt restoration of the hearing function as an important precondition for development of the language, social, emotional and academic development of children.

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two

  15. Immunohistochemical expression of MYB in salivary gland basal cell adenocarcinoma and basal cell adenoma.

    2017-10-01

    Basal cell predominant salivary gland neoplasms can be difficult to separate histologically. One of the most aggressive of basaloid salivary gland neoplasms is adenoid cystic carcinoma. MYB expression by immunohistochemistry has been documented in adenoid cystic carcinoma. Some investigators have suggested that using this expression can help in establishing the diagnosis of adenoid cystic carcinoma. Utilizing tissue microarrays, we studied a group of basal cell adenocarcinomas and basal cell adenomas to determine: (i) whether either tumor expressed MYB and (ii) the frequency of any expression in either tumors. Seventeen salivary gland basal cell adenocarcinomas and 30 salivary gland basal cell adenomas were used to construct microarrays. These tissue microarrays were used to assess for immunohistochemical MYB expression. Fifty-three percent (nine of 17) of salivary gland basal cell adenocarcinomas and 57% (17 of 30) of salivary gland basal cell adenomas showed MYB overexpression. For comparison, we studied 11 adenoid cystic carcinomas for MYB expression and found that 64% (seven of 11) overexpressed MYB. We found no relation to clinical course for basal adenomas or basal cell adenocarcinomas that overexpressed MYB vs those that did not. MYB expression does not help separate basal cell adenocarcinomas from basal cell adenomas, and our data suggest it does not differentiate between either of these neoplasms and adenoid cystic carcinoma. © 2017 John Wiley & Sons A/S.

    2006-01-01

    Full Text Available Adventitial cystic disease (ACD is an unusual cystic tumor of blood vessels characterized by the accumulation of mucinous substance in the adventitia of the non-axial blood vessels adjacent to joints. Patients with ACD often suffer from intermittent claudication and/or limb pain, mostly involving the popliteal artery. We report a 30-year-old male who presented with intermittent claudication in his left leg. Angiography showed an obstructive lesion in the left popliteal artery. The lesion was treated successfully by surgical excision followed by graft vessel replacement. ACD involving the popliteal artery was diagnosed by pathologic findings of multiple cysts of the adventitia with external compression and focal narrowing of the vascular lumen. The cysts contained acid mucin and were partially lined by multiple rows of cytologically bland, synovium-like cells with positive immunoreactivity to vimentin and CD68 but negative immunoreactivity to cytokeratin. The histopathologic findings in this case suggest that it was caused by the developmental rests of mucin-secreting mesenchymal cells derived from the knee joint.

    The authors reviewed adult cystic fibrosis patients followed in the Pulmonology Unit from 1994-2004 (n=8), five female and three male, aged 20-34 years old (median= 27 years). Patients were diagnosed at 18 months - 31 years old by sweat testing (positive in six patients) and genotyping (four patients homozygous for Delta F508 mutation). Respiratory involvement was characterised by sinusitis and bronchiectasis. Pulmonary involvement was accompanied by functional abnormalities and gas exchange impairment in the majority of the patients. Bronchial tree was colonised permanently in five patients: Pseudomonas aeruginosa in four and Staphilococcus aureus in four (three patients affected by both agents simultaneously). The main causes of exacerbation were respiratory infections and haemoptysis. Non-respiratory involvement was variable. Four patients had digestive involvement (one with hepatic cirrhosis), one had renal failure and only one had a sperm count to document infertility. Four patients had osteopaenia. Treatment included chest physiotherapy, bronchodilators, dornase alfa, mucolytics, digestive enzymes, vitamins, antibiotics and oxygen therapy. At review, one had left follow-up, one had died, one was awaiting lung transplant and the others evidenced no difference in clinical characteristics. In this group of patients the severity of the pulmonary disease was not related to a late diagnosis. It can be explained by the diversity of cystic fibrosis presentation in adults.

    A female congenic rat produced by repeated backcrossing of Nihon rats, a model for hereditary renal cell carcinoma, to Brown Norway rats was necropsied at 24 months of age. At necropsy, a white mass about 1 centimeter in size was observed in the thoracic cavity, and the mass partly adhered to the esophagus and the diaphragm. Histologically, the mass was clearly circumscribed by connective tissue, and consisted of neoplastic cuboidal epithelial cells that showed cystic tubular proliferation. Some islands of well-differentiated hepatocytes and some vessels were observed in the mass. Immunohistochemically, the tumor cells were strongly positive for cytokeratin and partly positive for vimentin but were negative for mesothelin and Von Willebrand Factor. The positive rate for Ki-67 was 2.4%. Based on these histological and immunohistochemical evidences, we diagnosed this tumor as a cystic cholangioma that might have arisen from the ectopic hepatic tissue in the thoracic cavity.

    Human bocavirus 1 (HBoV1) is associated with respiratory infections worldwide, mainly in children. Similar to other parvoviruses, it is believed that HBoV1 can persist for long periods of time in humans, probably through maintaining concatemers of the virus single-stranded DNA genome in the nuclei of infected cells. Recently, HBoV-1 was detected in high rates in adenoid and palatine tonsils samples from patients with chronic adenotonsillar diseases, but nothing is known about the virus replication levels in those tissues. A 3-year prospective hospital-based study was conducted to detect and quantify HBoV1 DNA and mRNAs in samples of the adenoids (AD), palatine tonsils (PT), nasopharyngeal secretions (NPS), and peripheral blood (PB) from patients undergoing tonsillectomy for tonsillar hypertrophy or recurrent tonsillitis. HBoV1 was detected in 25.3% of the AD samples, while the rates of detection in the PT, NPS, and PB samples were 7.2%, 10.5%, and 1.7%, respectively. The viral loads were higher in AD samples, and 27.3% of the patients with HBoV had mRNA detectable in this tissue. High viral loads and detectable mRNA in the AD were associated with HBoV1 detection in the other sample sites. The adenoids are an important site of HBoV1 replication and persistence in children with tonsillar hypertrophy. The adenoids contain high HBoV1 loads and are frequently positive for HBoV mRNA, and this is associated with the detection of HBoV1 in secretions. Copyright © 2014, American Society for Microbiology.

  20. Gastrointestinal Manifestations of Cystic Fibrosis

    Science.gov (United States)

    2016-01-01

    Cystic fibrosis has historically been considered a pulmonary disease, but with the increasing life expectancy of these patients, gastrointestinal manifestations are becoming more important. Furthermore, nutritional status is closely linked to pulmonary function and, thus, overall mortality. This article discusses gastrointestinal manifestations (which involve nutritional, pancreatic, hepatobiliary, and, in particular, gastrointestinal tract issues) of cystic fibrosis as well as management of the disease. In addition, the article discusses studies that have been critical to our understanding of gastrointestinal manifestations of cystic fibrosis. PMID:27330503

    Full Text Available By 1996, the median survival of patients with cystic fibrosis (CF in North America had increased to 31 years. With the markedly improved life expectancy, many CF patients are now adults. There is an associated increased risk of certain colonic disorders, and the emergence of other previously unrecognized disorders, in adult CF patients. The distal intestinal obstruction syndrome (DIOS, which is more common in older patients, is a frequent cause of abdominal pain. Intussusception may complicate DIOS; other differential diagnoses include appendiceal disease, volvolus, Crohn's disease, fibrosing colonopathy and colonic carcinoma. The diagnosis of acute appendicitis, although uncommon in patients with CF, is often delayed, and appendiceal abscess is a frequent complication. The prevalence of Crohn's disease in CF has been shown to be 17 times that of the general population. Right-sided microscopic colitis is a recently recognized entity in CF of uncertain clinical significance. Fibrosing colonopathy has been confined mostly to children with CF, attributed to the use of high strength pancreatic enzyme supplements, but it has been reported in three adults. Nine cases of carcinoma of the large intestine have been reported worldwide, associated with an apparent excess risk of digestive tract cancers in CF. Despite high carrier rates of Clostridium difficile in patients with CF, pseudomembranous colitis is distinctly rare, but severe cases complicated by toxic megacolon have been reported. In these patients, watery diarrhea is often absent. Adult CF patients with refractory or unexplained intestinal symptoms merit thorough investigations.

    Adenoid hypertrophy is known as the most common cause of nasal obstruction in children; thus, adenoidectomy with, or without, tonsillectomy is one of the most commonly performed surgical procedures in the paediatric population. Although many methods have been suggested, few studies have reported on how to assess adenoid size, pre-operatively. Acoustic rhinometry is an objective technique as well as a non-invasive method, which can be easily used in young children. This study confirmed that acoustic rhinometry is a non-invasive and objective technique for assessing the geometry of the nasal cavity and nasopharynx. Forty children were evaluated using symptomology, two different radiological measurements and acoustic rhinometry; the results were compared with endoscopic findings. Clinical symptoms and A/N ratio measured with Fujioka's method significantly correlated with the endoscopic assessment findings (r = 0.769 and 0.604 respectively). Significant increases in the cross-sectional area and volume of the nasopharynx were observed at the adenoid notch after adenoidectomy (p endoscopy and can be used as one of the pre-operative examination tools for adenoidectomy.

    Conclusion: A literature review revealed that this was a rare case of combined ABC–SCC associated with HPV 31 infection. In this case, the ABC component did not affect the tumor stage because it was confined to the cervix. However, we must avoid overestimating the clinical stage because the ABC component is thought to be a benign lesion.

    Full Text Available It was generally believed that Cystic fibrosis (CF is rare among Arabs; however, the few studies available from Egypt and other Arabic countries suggested the presence of many undiagnosed patients. The aim of the present study was to determine the frequency of CF patients out of the referred cases in a single referral hospital in Egypt. A total of 100 patients clinically suspected of having CF were recruited from the CF clinic of the Allergy and Pulmonology Unit, Children’s Hospital, Cairo University, Egypt, throughout a 2 year period. Sweat chloride testing was done for all patients using the Wescor macroduct system for collection of sweat. Quantitative analysis for chloride was then done by the thiocyanate colorimetric method. Patients positive for sweat chloride (⩾60 mmol/L were tested for the ΔF508 mutation using primer specific PCR for cystic fibrosis transmembrane conductance regulator (CFTR gene. Thirty-six patients (36% had a positive sweat chloride test. The main clinical presentations in patients were chronic cough in 32 (88.9%, failure to thrive in 27 (75%, steatorrhea in 24 (66.7%, and hepatobiliary involvement in 5 (13.9%. Positive consanguinity was reported in 50% of CF patients. Thirty-two patients were screened for ΔF508 mutation. Positive ΔF508 mutation was detected in 22 (68.8% patients, 8 (25% were homozygous, 14 (43.8% were heterozygous, and 10 (31.3% tested were negative. CF was diagnosed in more than third of patients suspected of having the disease on clinical grounds. This high frequency of CF among referred patients indicates that a high index of suspicion and an increasing availability of diagnostic tests lead to the identification of a higher number of affected individuals.

    Metaplastic carcinoma of the breast is a rare disease. We describe the MRI findings with the correlative sonographic and pathologic features of two cases. On MRI, T2-weighted images demonstrate a relatively well-defined mass with high signal intensity cystic components. Dynamic enhancement subtraction images showed an early enhancing and delayed washout peripheral rim and non-enhancing internal components. A microlobulated, isoechogenic mass with cystic components was seen sonographically, and was histopathology related to necrosis and cystic degeneration. Although these features are not unique, metaplastic carcinoma should be included in the differential diagnosis for breast masses.

    Renal cystic diseases encompass a broad group of disorders with variable phenotypic expression. Cystic disorders can present during infancy, childhood, or adulthood. Often, but not always, they can be distinguished by the clinical features including age at presentation, renal imaging characteristics, including cyst distribution, and the presence/distribution of extrarenal manifestations. It is important to take the clinical context into consideration when assessing renal cystic disease in children and adults. For example, solitary kidney cysts may be completely benign when they develop during adulthood but may represent early polycystic kidney disease when observed during childhood. In this review, we have categorized renal cystic disease according to inherited single-gene disorders, for example, autosomal recessive polycystic kidney disease; syndromic disorders associated with kidney cysts, for example, tuberous sclerosis complex; and nongenetic forms of renal cystic disease, for example, simple kidney cysts. We present an overview of the clinical characteristics, genetics (when appropriate), and molecular pathogenesis and the diagnostic evaluation and management of each renal cystic disease. We also provide an algorithm that distinguishes kidney cysts based on their clinical features and may serve as a helpful diagnostic tool for practitioners. A review of Autosomal Dominant Polycystic Disease was excluded as this disorder was reviewed in this journal in March 2010, volume 17, issue 2. Copyright © 2015 National Kidney Foundation, Inc.

    Malignant struma ovarii is a rare from of ovarian carcinoma. Since it is often seen as a nonspecific complex mass, its preoperative diagnosis is difficult. The MR imaging findings of benign struma ovarii have been reported, but no published account has described the malignant form. In this case, MR images depicted multiple cysts with well enhanced solid portions in the left ovary, and the typical appearance of mature cystic teratoma in the right ovary. We describe a case of malignant struma ovarii associated with mature cystic teratoma of the contralateral ovary.

    To describe the imaging features of unusual intracranial cystic meningiomas in infants and adults. We retrospectively reviewed the magnetic resonance and computed tomography findings for 2 female patients and 3 male patients, ranging in age from 1 to 73 years (median 41 years), with histopathologically proven cystic meningioma. Although cystic meningiomas usually appear as solid and cystic masses, they may present as a mainly multicystic lesion. The wall of a cystic part of the meningioma may include both enhancing and unenhancing areas at imaging. The cystic portion of a meningioma is hypointense on diffusion-weighted images and markedly hyperintense on corresponding apparent diffusion coefficient maps. (author)

  11. PATTERN OF LOCAL IMMUNE ALTERATIONS IN THE PATIENTS WITH CHRONIC ADENOIDITIS, AND AN OPPORTUNITY OF THEIR CORRECTION WITH IMUNOFAN

    Full Text Available Abstract. The issue of chronic adenoiditis, due to its medical and social significance, is in focus of attention for otolaryngologists, pediatricians, immunologists. According to various works, chronic adenoiditis in children comprise 20 to 56% of upper respiratory diseases. Chronic adenoiditis is characterized by relative resistance to conventional therapy, and, in pronounced cases, by low reversibility of pathological events. The studies performed have shown that the patients with chronic adenoiditis show some features of local and general immune deficiency that were exhibited as decreased serum IgA concentration and local sIgA secretion, as well as insufficient income of IgG from vascular system to the area of inflammation in patients with chronic adenoiditis. These local immune deficiencies were considered to be an indication for local immunotherapy. Dynamics of clinical symptoms and changes in immunoglobulin profile has shown that clinical efficiency of Imunofan therapy was dependent not solely on the initial clinical features of disease, but on the local immunity state. Analysis of initial immunoglobulin concentrations in nasopharyngeal lavage from the patients showing differential clinical response have demonstrated that therapeutic effect of Imunofan was most pronounced in the patients with initially moderate activity of inflammatory process, deficient IgG income from vascular system, decreased local IgA synthesis in the inflammatory foci. Certain clinical features of chronic adenoiditis, i.e., clinical course without hypertrophy of pharyngeal tonsils, local immune deficiency (decreased local IgA secretion and deficient IgG income from blood, with a background of moderate inflammatory events, may be used as a rationale for administration of local immunotherapy with Imunofan to these patients.

    Pancreatic cystic neoplasm is a relatively rare potential neoplasm in clinical practice and has a low-grade malignancy. Pancreatic cystic neoplasm is classified as serous cystic neoplasm, mucinous cystic neoplasm, intraductal papillary mucinous neoplasm, and solid pseudopapillary neoplasm. Due to its complex pathological type and the deep location of the pancreas, patients often lack typical clinical symptoms and signs, which may easily lead to misdiagnosis or missed diagnosis.

    Whereas pancreatic duct adenocarcinoma (PDA) is a well-studied (but still poorly understood) disease with a dismal prognosis, cystic neoplasms of the pancreas form a more recently recognized group of pancreatic tumors. They are diverse and variable in their pathologic characteristics, clinical course, and outcomes,1–3 although all portend a better overall prognosis than PDA. In recent years, with the improved sensitivity and increasing use of cross-sectional imaging in clinical practice, these lesions are more commonly identified,4 with many being discovered incidentally. Indeed, large radiological series using computed tomography (CT) or magnetic resonance imaging (MRI) have reported detection rates of pancreatic cystic lesions between 1.2% and almost 20%,5,6 approaching the 24.3% prevalence rate in an autopsy series by Kimura and colleagues.7 Although most of these lesions are pseudocysts, a significant portion consist of cystic neoplasms, which are estimated to represent 10% to 15% of all primary pancreatic cystic lesions.8 Given the growing clinical relevance of these tumors, a keen understanding of their natural history and pathophysiology is needed. This article reviews pancreatic cystic neoplasms, with a focus on the challenges encountered in their diagnosis and treatment. PMID:20159515

  1. The macrophage origin of the HIV-expressing multinucleated giant cells in hyperplastic tonsils and adenoids.

    Science.gov (United States)

    Orenstein, J M; Wahl, S M

    1999-01-01

    Replication and storage of virus are characteristic features of hyperplastic lymphoid tissues in HIV infection. In opportunistic infections, HIV is synthesized by phagocytic mononuclear and Langhans'-type multinucleated macrophages that coexpress the dendritic cell-associated S-100 and p55 antigens. However, similar cells in hyperplastic tonsils and adenoids from HIV+ individuals were alternatively identified as macrophages or, on the basis of the same S-100 and p55 staining, as dendritic cells. To consider establishing the role of these HIV-rich cells in HIV disease, it is important to reconcile this apparent discrepancy in identity. Hyperplastic tonsils and adenoid specimens were analyzed by HIV RNA in situ hybridization (ISH), light and transmission electron microscopy (TEM), and immunohistochemistry (IHC) (HIV Gag p24 protein, S-100, p55, CD68, HAM56, lysozyme, alpha-1-anti-trypsin, and alpha-1-anti-chymotrypsin). In HIV+ pediatric and adult surgical specimens (n = 11), the giant cells and their mononuclear counterpart were positive for both macrophage and p55 and S-100 IHC markers. In addition, TEM, p24 IHC, and ISH showed HIV expression by cells with typical features of macrophages. Furthermore, these cells were not unique to HIV+ specimens, being seen in 20% of hyperplastic T&A surgical specimens (n = 57) lacking HIV as well as in several types of granulomatous processes, such as sarcoidosis. These cells appear to represent an activated phenotype that can develop independent of HIV, but that may represent a viral host in HIV-infected individuals. Thus, the giant and mononuclear cells that produce striking amounts of HIV in tonsils and adenoids are of macrophage origin, yet, as in opportunistic infections, share dendritic cell-associated antigens, reflecting a common CD34+ bone marrow progenitor.

    A 74-year-old woman with multiple cystic lesions in the pancreas was first examined at a previous hospital. Many of the lesions in the head and body were diagnosed as a branch duct intraductal papillary mucinous neoplasms (IPMN), but one lesion in the tail was a simple cyst. She had no surgical treatment because there were no signs of malignancy in any of the lesions. After 3 years, solid components appeared only in the tail lesion. Because of its preoperative diagnosis as a mucinous cystic neoplasm (MCN), distal pancreatectomy was performed. Histopathological findings revealed that the cystic tumour in the tail was IPMN with minimally invasive carcinoma and the other lesion in the body was IPMN with low-grade dysplasia. They were IPMNs bridged by a non-dilated main pancreatic duct. There may be some cases in which it is difficult to diagnose between IPMN and MCN.

    Fibroadenomas with a predominant cystic change are called cystic fibroadenomas. These are extremely rare forms of fibroadenomas and only one case has been reported so far. They are classified under the category of complex fibroadenomas. Complex fibroadenomas are a rare variant of fibroadenomas occurring in elderly females. They are characterized by presence of one of the complex features along with the usual patterns of fibroadenoma such as cysts more than 3 mm, papillary apocrine metaplasia, or sclerosing adenosis. Patients with these lesions have higher chances of developing carcinoma of breast. We present a case of 35 years old lady with a freely mobile mass in the left breast diagnosed as cystic fibroadenoma after thorough histopathological examination of the lesion.

    Full Text Available A retrospective review of 32 patients with basal cell carcinoma was performed with aims to characterize the demographic profile and to analyze the clinical and histological parameters influencing the treatment of basal cell carcinoma. The maximum number occurred in the sixth decade with an unusual female preponderance. Hisologically, the classic type predominated while the other types included pigmented, morphoea, metatypical, adenoid, eccrine, firoepihelioma and superficial spreading type. All patients had excision of the tumour with involvement of surgical margin in three of them. None of the three patients belonged to aggressive histological types, such as morphoea or metatypical type. Two year follow-up showed no recurrence. Size of the tumor less than 2 cm, absence of ulceration and a good inflammatory response were probably other reasons for non-recurrence.

    Serous cystic neoplasms (SCNs) are benign cystic neoplasms that predominantly occur in the tail of the pancreas in elderly women. It is well known that patients with von Hippel-Lindau syndrome can develop SCNs and neuroendocrine tumors in the pancreas. However, our understanding on SCNs accompanying other pancreatic tumors (SCNAOPTs) is limited. We compared the clinicopathological features of 15 surgically resected SCNAOPTs with 259 conventional SCNs. The prevalence of SCNAOPT was 5%. The SCNAOPTs were significantly smaller than conventional solitary SCNs, and they were more commonly observed in the head of the pancreas, whereas conventional solitary SCNs were more frequently noted in the body and tail. However, no differences were found in terms of sex, patient age, or the gross patterns of the SCNs. Accompanying neoplasms included 7 intraductal papillary mucinous neoplasms, 1 colloid carcinoma arising from intraductal papillary mucinous neoplasm, 6 neuroendocrine tumors, and 1 solid pseudopapillary neoplasm. Four neuroendocrine tumors associated with von Hippel-Lindau syndrome occurred as multiples, whereas 2 neuroendocrine tumors without von Hippel-Lindau syndrome were solitary. In summary, SCNAOPTs comprise 5% of all SCNs and tend to be smaller and located in the head of the pancreas. Common accompanying tumors include intraductal papillary mucinous neoplasms, neuroendocrine tumors, and other neoplasms such as colloid carcinoma and solid pseudopapillary neoplasm.

Sixty-five consecutive patients (48 men) with suspected NPC were examined using a 3.0-T MR system. Diffusion-weighted imaging (DWI) was performed with 13 b values (range, 0-800 s/mm{sup 2}). We regarded the result of endoscopy and biopsy as the gold standard for detection. D, D* and f were compared between patients with primary NPC and enlarged adenoids. IVIM DWI was successful in 37 of 40 NPC and 23 of 25 enlarged adenoids cases. D (P = 0.001) and f (P < 0.0001) were significantly lower in patients with NPC than in patients with enlarged adenoids, whereas D* was significantly higher (P < 0.0001). However, the ADC was not significantly different between the two groups (P > 0.05). The area under the ROC curve (AUC) for D was 0.849 and was significantly larger than that for ADC (P < 0.05). IVIM DWI is a feasible technique for investigating primary NPC. D was significantly decreased in primary NPC, and increased D* reflected increased blood vessel generation and parenchymal perfusion in primary NPC. (orig.)

  8. The ultrastructural localization of gross cystic disease fluid protein (GCDFP-15) in breast epithelium.

    GCDFP-15 is a major constituent protein of 15,000-dalton monomer size present in breast gross cystic disease fluid. Immunoperoxidase staining of GCDFP-15 has shown the protein to be present in normal apocrine epithelium, metaplastic apocrine epithelium of the breast, and breast carcinomas with apocrine features. To delineate ultrastructurally the localization of GCDFP-15 in benign breast epithelium, a low-temperature embedding colloidal gold technique was used. Metaplastic apocrine epithelium...

    This study aimed to explore adenoid regrowth after transoral power-assisted adenoidectomy down to the pharyngobasilar fascial surface. Transoral adenoidectomy down to the pharyngobasilar fascia surface was performed on 39 patients under endoscopic guidance, using a power-assisted system. The operation time, amount of blood loss and iatrogenic injury, presence of complications, and success and regrowth rates were recorded to assess the feasibility, safety and effectiveness of our surgical technique. In this adenoidectomy procedure, the pharyngobasilar fascia was left intact. The estimated blood loss was 5-50 ml (mean 15 ml), and the success rate was 97.3 per cent. Early complications occurred in 2.3 per cent of patients, while no long-term complications occurred in the cohort. No regrowth was found in the follow-up assessments, which were performed for 18-36 months after surgery. Adenoid regrowth was rare after adenoidectomy down to the pharyngobasilar fascial surface. The pharyngobasilar fascia can therefore be considered a surgical boundary for adenoidectomy.

    1992-01-01

    A human mammary carcinoma originating from a postmenopausal patient was successfully transplanted into nude mice. According to the adopted criteria the tumour proved to be oestradiol- and progesterone-receptor-positive. Histological studies of the patient tumour revealed a ductal invasive mammary carcinoma with 80% tubular growth pattern. Following transplantation the adenoid structures decreased to 30%; the mitosis rate and grade of malignancy increased. Treatment of the nude mice with 20 micrograms oestradiol benzoate/mouse caused a loss of the oestradiol receptor of the mammary carcinoma. The mammary carcinoma 3366 can be used for testing of antineoplastic substances, antihormones and for studies in regard to down-regulation or blocking of hormone receptors and possible consequences for therapies.

    2015-09-01

    Biomarkers in cystic fibrosis are used i. for the measurement of cystic fibrosis transmembrane regulator function in order to diagnose cystic fibrosis, and ii. to assess aspects of lung disease severity (e.g. inflammation, infection). Effective biomarkers can aid disease monitoring and contribute to the development of new therapies. The tests of cystic fibrosis transmembrane regulator function each have unique strengths and weaknesses, and biomarkers of inflammation, infection and tissue destruction have the potential to enhance the management of cystic fibrosis through the early detection of disease processes. The development of biomarkers of cystic fibrosis lung disease, in particular airway inflammation and infection, is influenced by the challenges of obtaining relevant samples from infants and children for whom early detection and treatment of disease might have the greatest long term benefits.

    Cystic fibrosis is the most common life-shortening recessively inherited disorder in the Caucasian population. The genetic mutation that most frequently provokes cystic fibrosis (ΔF508) appeared at least 53,000years ago. For many centuries, the disease was thought to be related to witchcraft and the "evil eye" and it was only in 1938 that Dorothy H. Andersen characterized this disorder and suspected its genetic origin. The present article reviews the pathological discoveries and diagnostic and therapeutic advances made in the last 75 years. The review ends with some considerations for the future. Copyright © 2015 Elsevier España, S.L.U. and AEEH y AEG. All rights reserved.

    Chandwani, Rohit; Allen, Peter J

    2016-01-01

    Cystic neoplasms of the pancreas are being identified at an increasing frequency largely due to the increased use of abdominal cross-sectional imaging. These neoplasms represent a heterogeneous group of tumors with various genetic alterations, molecular features, and risks of malignancy. Despite the use of high-resolution radiographic studies, endoscopic evaluation, cyst fluid analysis, and novel molecular diagnostics, many of these lesions remain difficult to classify without operative resection. These diagnostic challenges are coupled with an improving but limited understanding of the natural history of these neoplasms. Treatment of pancreatic cystic neoplasms therefore remains controversial but consists largely of a selective tumor-specific approach to surgical resection. Future research remains necessary to better discriminate the biological behavior of these tumors in order to more appropriately select patients for operative intervention.

The mass had grown for 6 years, after she had sustained a head injury at the age of 6, and was located directly under a previous wound. Skull X-ray Photograph (xp, computed tomography (CT, and magnetic resonance imaging (MRI showed a bony defect and cystic changes in the skull corresponding to a subcutaneous mass. Bone scintigraphy revealed partial accumulation. The patient underwent total removal of the skull mass, and the diagnosis from the pathological findings of the cyst wall was fibrous dysplasia (FD. The radiographic findings for cystic cranial FD can be various. Progressive skull disease has been reported to be associated with head trauma, but the relationship between cranial FD and head trauma has not been previously reported. Previous studies have suggested that c-fos gene expression is a key mechanism in injury-induced FD.

    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.

According to received data — to prove reasonability of usage of herbal drug with anti-inflammatory and immunostimulating effects in a complex treatment of children with adenoiditis. Patients and methods: 22 healthy children (control group and 62 children with chronic adenoiditis (CA were examined. Results: it was found that serum concentration of MG, MG-IgG, α1-antitrypsin and IL 10 is significantly higher in children with CA. The level of lactoferrin is also increased. The abovementioned changes in coupled with tendency to decrease of IL 8 concentration in CA suggest that this condition is characterized mainly by compensated immune reactions according to Th2-type. However, certain characteristics of protein and cytokine metabolism in CA contribute to chronization of pathological process, which clinically is manifested by prolonged torpid inflammation. Taking into account special features of CA pathogenesis and in order to increase efficacy of treatment of this disorder an herbal drug with complex action was used. Conclusions: including of the studied drug into the scheme of CA treatment increases efficacy of provided therapy and accelerates temps of convalescence. The drug is safe and can be used for prolonged periods of time.

    It is generally accepted that dopamine agonists (DA) represent the first-line treatment for most patients with prolactinoma, and patients become candidates for surgical intervention when DA is contraindicated. Surgical indication for cystic prolactinoma remains controversial. This study was performed to investigate the significance of surgery for cystic prolactinoma. A total of 28 patients that underwent transsphenoidal resection of prolactinoma between February 2004 and May 2016 were reviewed. Five consecutive patients with cystic prolactinoma were included in this study. Our surgical strategy for cystic prolactinoma was categorized as follows: first, when the purpose of surgical resection was normalization of the prolactin level, aggressive resection was performed; second, when volume reduction was essential to relieve the visual symptoms and headache, internal decompression was performed followed by DA therapy. The clinical outcomes were analyzed accordingly. All cystic prolactinoma were resected via the transsphenoidal approach without any complications, and all symptoms including visual impairment and hypogonadal activity were finally relieved combined with medication. Surgery for cystic prolactinoma could be a better option. Transsphenoidal surgery is relatively safe to remove the cystic prolactinoma, additionally it can normalize the prolactine level and achieve adequate and rapid decompression of optic chiasm. The risk of transsphenoidal surgery is highly dependent on the skill of the surgeon and treatment decision for cystic prolactinoma needs to be individualized for each patient.

    There is evidence that exposure to passive smoke is associated with an increased susceptibility to respiratory infections. Indeed, cigarette smoke extracts may interfere with the immune system, even though the precise mechanism has not been fully understood yet. Recurrent respiratory infections may be sustained by a defective immune response. The aim of the present study was to evaluate whether, in a cohort of children presenting both with recurrent respiratory infections and with a history of exposure to tobacco smoke, these factors were related to a lower local production of interferon-gamma (IFN-gamma) when compared to a similar non-exposed population. The study group included 128 children undergoing adenoidectomy, presenting with more than three respiratory infections per year, independently of exposure to passive smoke at home. The intracellular cytokine profile of lymphocyte subsets in adenoids was evaluated by flow cytometry analysis. Children exposed to tobacco smoke suffered from a significantly greater number of respiratory infections and had a lower percentage of IFN-gamma-producing CD8+ cells in adenoids than non-exposed children, while other T-cell subsets were not affected. The effect of smoke exposure seems to be specific to the IFN-gamma-producing CD8+ cells in adenoids and may contribute to the increased susceptibility to the recurrence of respiratory infections.

    The ultimobranchial bodies in human embryos develop from the fourth and fifth branchial pouch complexes along with thymic and parathyroid tissue. They become incorporated within the lateral thyroid lobes and are believed to be involved in the development of C-cells. We report a case of an unusual bilateral thyroid and neck prelaryngeal medullary carcinoma in a 23-year-old male patient who belongs to a multiple endocrine neoplasia type 2a (MEN type 2a) family with thyroid tumors and pheochromocytomas. The medullary carcinoma was located in an abnormal cystic structure that seems to be a remnant of the ultimobranchial body (UBB) in the neck. Within the contralateral thyroid lobe, the medullary carcinoma was associated with C-cell hyperplasia.

    Full Text Available Background: As a part of pre-operative evaluation, several otolaryngologists group and cross-match blood routinely for children undergoing adenoid and tonsil surgeries. This practice has generated several debates either in support or against this practice. The aim of this study is to critically evaluate the incidence of post-tonsillectomy (with or without adenoidectomy bleeding and blood transfusions in otherwise healthy children with adenoid/tonsil pathologies conducted in the University of Port Harcourt Teaching Hospital (UPTH. Patients and Methods: A descriptive retrospective study of children who underwent adenoid and tonsil surgeries in the Department of Ear, Nose and Throat (ENT surgery of UPTH from January 2003 to December 2012. Children with family history of bleeding disorders and derangement of clotting profile as well as different co-morbidity like sickle cell disease were excluded from this study. The patients′ data were retrieved from the registers of ENT out-patient clinics, theatre registers and patients case notes. Demographic data, indications for surgery, preoperative investigations, complications and management outcomes were recorded and analyzed. Results: Out of 145 children that had adenoid and tonsil surgeries; only 100 met the criteria for this study. The study subjects included 65 males and 35 females (male: female ratio 1.9:1 belonging to 0-16 years age group (mean age: 3.46 ± 2.82 years. The age group of 3-5 years had the highest (n = 40, 40% number of surgeries. Adenotonsillectomy was the commonest (n = 85, 85% surgery performed on patients who had obstructive sleep apnea (OSA. The commonest (n = 6, 6% complication was haemorrhage, and only few (n = 3, 3% patients had blood transfusion. However, mortality was recorded in some (n = 3, 3% patients. Conclusion: This study confirms that the incidence of post adenoidectomy/tonsillectomy bleeding in otherwise healthy children is low and rarely requires blood transfusion

    Several agents are used to clear secretions from the airways of people with cystic fibrosis. Inhaled dry powder mannitol is now available in Australia and some countries in Europe. The exact mechanism of action of mannitol is unknown, but it increases mucociliary clearance. Phase III trials of inhaled dry powder mannitol for the treatment of cystic fibrosis have been completed. The dry powder formulation of mannitol may be more convenient and easier to use compared with established agents which require delivery via a nebuliser. To assess whether inhaled dry powder mannitol is well tolerated, whether it improves the quality of life and respiratory function in people with cystic fibrosis and which adverse events are associated with the treatment. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises references identified from comprehensive electronic databases, handsearching relevant journals and abstracts from conferences.Date of last search: 16 April 2015. All randomised controlled studies comparing mannitol with placebo, active inhaled comparators (for example, hypertonic saline or dornase alfa) or with no treatment. Authors independently assessed studies for inclusion, carried out data extraction and assessed the risk of bias in included studies. The searches identified nine separate studies (45 publications), of which four studies (36 publications) were included with a total of 667 participants, one study (only available as an abstract) is awaiting assessment and two studies are ongoing. Duration of treatment in the included studies ranged from two weeks to six months with open-label treatment for an additional six months in two of the studies. Three studies compared mannitol with control (a very low dose of mannitol or non-respirable mannitol); two of these were parallel studies with a similar design and data could be pooled, where data for a particular outcome and time point were available; also, one short

    Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

    Full Text Available We present a case of cystic lymphangioma of the mediastinum complicated with situs inversus totalis. The 70-year-old man underwent thoracoscopic resection of a mediastinal cystic tumor, which was diagnosed as cystic lymphangioma. Cystic lymphangiomas are congenital cystic abnormalities of the lymphatic system. The head and neck area is often involved while the mediastinum is rarely affected. The rarity of this case is further attributed to the coexistence of situs inversus totalis.

    MR assessments of ovarian cystic lesions are usually based on morphological features, signal intensities and enhancement with contrast media. This study was performed to evaluate the usefulness of the steady-state free precession (SSFP) diffusion imaging of cystic ovarian lesions for analyzing cystic contents. Sixty-one ovarian cystic lesions in 37 patients were examined. The diffusion-related coefficient (DRC) and the ratio of the relative apparent diffusion coefficient of the lesion to that of subcutaneous fat tissue (rADC{sub L}/rADC{sub F}) were calculated from SSFP diffusion images. The DRCs and the rADC{sub L} /rADC{sub F} ratios in endometrial cysts and in the fatty parts of dermoid cysts were significantly lower than in other cystic tumors. SSFP diffusion imaging can be included in clinical practice to analyze ovarian cystic lesions within a short scan time; the DRC and the rADC{sub L} /rADC{sub F} ratio are useful for evaluating cystic contents.

    People with cystic fibrosis and pancreatic insufficiency are at risk of fat soluble vitamin deficiency as these vitamins (A, D, E and K) are co-absorbed with fat. Thus, some cystic fibrosis centres routinely administer these vitamins as supplements but the centres vary in their approach of addressing the possible development of deficiencies in these vitamins. Vitamin A deficiency causes predominantly eye and skin problems while supplementation of vitamin A to excessive levels may cause harm to the respiratory and skeletal systems in children. Thus a systematic review on vitamin A supplementation in people with cystic fibrosis would help guide clinical practice. To determine if vitamin A supplementation in children and adults with cystic fibrosis:1. reduces the frequency of vitamin A deficiency disorders;2. improves general and respiratory health;3. increases the frequency of vitamin A toxicity. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Trials Register which comprises of references identified from comprehensive electronic database searches and handsearches of relevant journals and abstract books of conference proceedings.Date of the most recent search of the Group's Cystic Fibrosis Trials Register: 07 April 2014. All randomised or quasi-randomised controlled trials comparing all preparations of oral vitamin A used as a supplement compared to either no supplementation (or placebo) at any dose and for any duration, in children or adults with cystic fibrosis (defined by sweat tests or genetic testing) with and without pancreatic insufficiency. No relevant studies for inclusion were identified in the search. No studies were included in this review. As there were no randomised or quasi-randomised controlled trials identified, we cannot draw any conclusions on the benefits (or otherwise) of regular administration of vitamin A in people with cystic fibrosis. Until further data are available, country or region specific guidelines on the use of

  5. Voice disorder in cystic fibrosis patients.

    Directory of Open Access Journals (Sweden)

    Bruna Mendes Lourenço

    Full Text Available Cystic fibrosis is a common autosomal recessive disorder with drastic respiratory symptoms, including shortness of breath and chronic cough. While most of cystic fibrosis treatment is dedicated to mitigating the effects of respiratory dysfunction, the potential effects of this disease on vocal parameters have not been systematically studied. We hypothesized that cystic fibrosis patients, given their characteristic respiratory disorders, would also present dysphonic symptoms. Given that voice disorders can severely impair quality of life, the identification of a potential cystic fibrosis-related dysphonia could be of great value for the clinical evaluation and treatment of this disease. We tested our hypothesis by measuring vocal parameters, using both objective physical measures and the GRBAS subjective evaluation method, in male and female cystic fibrosis patients undergoing conventional treatment and compared them to age and sex matched controls. We found that cystic fibrosis patients had a significantly lower vocal intensity and harmonic to noise ratio, as well as increased levels of jitter and shimmer. In addition, cystic fibrosis patients also showed higher scores of roughness, breathiness and asthenia, as well as a significantly altered general grade of dysphonia. When we segregated the results according to sex, we observed that, as a group, only female cystic fibrosis patients had significantly lower values of harmonic to noise ratio and an abnormal general grade of dysphonia in relation to matched controls, suggesting that cystic fibrosis exerts a more pronounced effect on vocal parameters of women in relation to men. Overall, the dysphonic characteristics of CF patients can be explained by dysfunctions in vocal fold movement and partial upper airway obstruction, potentially caused by the accumulation of mucus and chronic cough characteristic of CF symptomatology. Our results show that CF patients exhibit significant dysphonia and

  6. Cystic nephroma/mixed epithelial stromal tumor: a benign neoplasm with potential for recurrence.

    Cystic nephroma (CN) is a rare, benign, renal neoplasm composed of epithelial and stromal elements. Only about 200 cases have been reported since 1892 and recurrence has rarely been observed. We report a 32-year-old Hispanic woman, with a history of a right, complex cystic, renal mass treated by robotic decortication 2 years ago, who presented with flank pain, hematuria, and recurrent urinary tract infection. A magnetic resonance imaging study showed a 3.4-cm multicystic lesion with thickened septa and enhancement at the right kidney. The partial nephrectomy specimen revealed a well-circumscribed, multicystic tumor abutting the renal pelvis, with thick septa and smooth walls, filled with clear fluid. Microscopic examination showed variably sized cysts lined by cuboidal epithelium with focal hobnailing, without significant cytologic atypia and mitosis. The epithelial lining was positive for CK19, high molecular weight cytokeratin, and α-methylacyl-CoA racemase suggesting a primitive tubular epithelial phenotype. Primitive glomeruli-like structures were also present. The ovarian-like stroma was condensed around the cysts and was variably cellular with areas of muscle differentiation and thick-walled vessels. The stroma was positive for desmin, estrogen receptor, progesterone receptor, and CD10. We suggest that CN represents a variable mixture of epithelial and stromal elements, immature glomerular, tubular, muscle, and vascular elements, which may be present in variable proportions creating a spectrum of lesions previously described as CN and mixed epithelial and stromal tumors (MEST). This case emphasizes that CN/MEST clinically/radiologically mimics other cystic renal neoplasms, especially cystic renal cell carcinoma and tubulocystic carcinoma, necessitating histopathological examination and immunohistochemial studies for definitive diagnosis. Additionally, CN has the tendency to recur when not completely excised initially. © The Author(s) 2014.

    We examined the roles of Ultrasonography conductors by analyzing the results of tissue biopsy of complex cystic masse under the guidance of breast US. This study was performed to a group of 178 who showed breast US indicating complex cystic masses among 342 patients who were definitely diagnosed by tissue biopsies and operations in our hospital from June 30th, 2003 to June 30th, 2007. The evaluation of tissues around, calcification, the distribution state of blood flow were excluded from the analysis subjects and logic 200 made by GE corporation and gun for core biopsy(Kimal corp., K7/MBD23) were used in this study. The biopsy results of 178 subjects showed FCC (fibrocystic change)(n=56 : 31.4%), Fibrosis (n=41 : 23.0%), Fibroadenoma (n=20 : 11.2%), Epithelial hyperplasia (n=17 : 9.6%), Carcinoma (n=15 : 8.4%), Fibroadipose (n=8 : 4.5%), Sclerosing adenosis (n=7 : 3.9%), Duct ectasia (n=5 : 2.8%), Papiloma (n=5 : 2.8%), and Fat necrosis (n=1 : 0.6%), Hemangioma (n=1 : 0.6%), Abscess (n=1 : 0.6%), Dystrophic calcification(n=1 : 0.6%). The US showed that the results of the tissue biopsy of complex cystic masses were mostly carcinoma(8.4%). Most of them were benign and only 9.6% of epithelial hyperplasia which has high progression rate into malignant tumors epidemically showed malignancy. Most of them were included in the spectrum of fibrous cystic nodule. Even though these results are confirmed, further studies are required. As a result, a nodule which is not certified by US should be right to take the tissue biopsy, but if it's difficult due to patients or another reasons, re-check tests in three months are required. And systemic ultrasonography evaluation should be well recognized to conduct more careful and specific tests.

    A 48-year-old woman was admitted to our hospital with a palpable mass in her lower abdomen. A left ovarian, cystic mass containing multiple mobile globules was seen on CT and MR images. The outer portion of the globules showed fat components on CT and fat-saturated T1-weighted MR images. Ultrasonography showed multiple echogenic, mobile globules with some sound attenuation and hyper echoic lines and dots within the cystic mass, which corresponded with the presence of lipid globules and hair shafts of ovarian mature cystic teratoma, respectively

  10. Trismus as a rare presenting symptom in a pediatric nasopharyngeal carcinoma

    Directory of Open Access Journals (Sweden)

    N. Maithrea

    2017-03-01

    Full Text Available Nasopharyngeal carcinoma (NPC has a diverse incidence pattern but remains a rare tumour in the pediatric age group. Childhood nasopharyngeal carcinoma usually presents in the second decade of life. Paediatric NPC cases present a diagnostic challenge due to the high prevalence of common NPC presenting symptoms of nasal obstruction, serous otitis media and hearing problems among children. Furthermore, adenoid tissue is most often present, and a biopsy in an outpatient setup would be difficult. However, trismus on initial presentation is uncommon, and even in adults is a therapy related complication. As such, surgeons should have a high index of suspicion in NPC endemic areas, and a lower threshold for imaging in these cases as overall outcome appeared to be similar between adult and childhood NPC.

    2012-01-01

    Full Text Available Malignant transformation of ameloblastomas arising from an odontogenic cyst or de novo is well-recognized. Malignancies in ameloblastomas may involve metastasis or a local dysplastic change in the tissue. The latter are classified as ameloblastic carcinomas. A 75-year-old male presented with a mandibular cystic swelling, with no evidence of metastasis. Dysplastic ameloblastic cells with spindle-cell transformation were seen arising from a cystic lining with features of a unicystic ameloblastoma. Immunohistochemically the lesion stained positive with cytokeratin 8,19 and alpha smooth muscle actin, but was negative for vimentin. A diagnosis of spindle-cell ameloblastic carcinoma was made. Spindle-cell ameloblastic carcinomas are rare and this is the second case arising from a unicystic ameloblastoma reported in literature. The recognition of this transformation and inclusion of this entity in the classification of ameloblastic carcinomas is stressed.

  12. Pyelo-cystic Reflux in F-18 FDG PET Scan Due to Ureteral Obstruction

    Energy Technology Data Exchange (ETDEWEB)

    Reyhan, Mehmet [Baskent Univ., Adana (Turkmenistan)

    2013-09-15

    A 72-year-old woman with a history of cervical cancer was treated with brachytherapy and chemotherapy. Combined F-18 FDG PET/CT performed for restaging demonstrated increased FDG uptake in a hypodense cystic lesion at the posterior part of the right renal cortex and a hypermetabolic soft tissue mass at the right parailiac region suggestive of a metastatic lymph node causing ureteral obstruction. There had been no FDG uptake in the cystic lesion on the FDG PET/CT study performed 1 year before. These findings suggest that the increased FDG uptake in the cystic lesion was caused by pyelocystic reflux due to ureteral obstruction secondary to parailiac lymph node metastasis (Figs. 1 and 2). Several renal lesions may have increased metabolism, such as renal cell carcinoma, lymphoma, oncocytoma, adult Wilms' tumor, angiomyolipoma, metastatic lesions, xanthogranulo-matous pyelonephritis and infected cyst. Most of these lesions are solid. Some infected renal cysts may be FDG avid, but in this situation increased FDG uptake is observed on the wall of the cyst. In our case, FDG uptake was seen in the entire cystic lesion. The patient had no symptoms or laboratory findings related to infection. Cysts are the most common space-occupying lesions of the kidney. The vast majority of these are simple cysts that are usually unilateral and solitary. Simple cysts are asymptomatic, except when complications exist such as hemorrhage, infection or rupture. There have been a few reports on spontaneous communications between renal cysts and the pyelocaliceal system, in most cases involving ruptures of the cysts into the pyelocaliceal system due to increased intracystic pressure caused by bleeding or infection of the cyst. In the present case, the cause of the connection between the cystic cavity and the pyelocaliceal system is the increased pressure in the renal pelvic cavity due to the ureteral obstruction secondary to parailiac lymph node metastasis.

    The aim of this study was to assess the computed tomography (CT) features of intrapulmonary congenital cystic diseases in adults and to correlate the imaging features with the pathological findings, with emphasis on the oncogenic potential of the lesions. We retrospectively reviewed the CT scans in three institutions from August 1996 to December 2008, of nine patients (six men, three women; mean age 48.6 years; range 26-75 years) who had histological diagnosis of pulmonary cystic disease after surgery. Six patients had a diagnosis of intrapulmonary bronchogenic cyst (IBC), and three had a type-I cystic adenomatoid malformation (CAM). In one case, intralobar sequestration (ILS) was associated with type-I CAM. Three patients were symptomatic and six were asymptomatic. On CT scans, IBCs showed homogeneous fluid attenuation (n=2), air-fluid level (n=2), air attenuation (n=1) or soft-tissue attenuation (n=1). The surrounding lung tissue showed areas of band-like linear attenuation in three IBCs, atelectasia in two and mucocele-like areas in one. On CT, type-I CAM appeared as a unilocular cystic lesion with air-fluid level (n=1) or air content (n=1). Both cases had thin walls surrounded by normal lung parenchyma. ILS appeared as a fluid-filled cyst with afferent and efferent vessels. Of the six IBCs, one occurred in the upper right lobe, two in the middle lobe and three in the lower right lobe. Of the three type-I CAMs, one was in the upper left lobe and one in the middle lobe. The type-I CAM associated with ILS was located in the left lower lobe. The similar CT patterns preclude differentiation between IBC and type-I CAM. Surgical resection of all intrapulmonary cystic lesions detected in adults is mandatory because type-I CAM is a precursor of mucinous bronchioloalveolar carcinoma.

    Full Text Available INTRODUÇÃO: a hipertrofia de adenoide é uma das principais causas da respiração bucal. Entre os métodos utilizados para o diagnóstico dessa condição, os mais precisos são a endoscopia nasal e a ressonância magnética. No entanto, o método mais utilizado, em Odontologia, é a radiografia cefalométrica lateral. OBJETIVO: determinar a eficácia dessa radiografia no diagnóstico da hipertrofia de adenoide, pela sua comparação com a endoscopia nasal. MÉTODOS: foram avaliados 30 indivíduos (7 a 12 anos. Todos fizeram exame de endoscopia nasal e radiografia cefalométrica lateral. Nas endoscopias, foi registrada a porcentagem de obstrução da nasofaringe e, nas radiografias, a menor dimensão anteroposterior livre da nasofaringe. RESULTADOS: os exames se mostraram fortemente correlacionados (r = - 0,793, p-valor INTRODUCTION: One of the most usual causes of mouth breathing is adenoids hypertrophy with reduction of the nasopharyngeal space. The most precise diagnostic methods are magnetic resonance and nasal endoscopy, because they make possible a three dimension image of the nasopharynx. However, in Dentistry, cephalometric radiography is the method used in the majority of cases. That is why it is so important the evaluation of the efficacy of this diagnostic method. AIM: The aim of this paper is to determine the efficacy of the lateral cephalometric radiography in diagnosing adenoids hypertrophy, comparing this method to the nasal endoscopy. METHODS: Thirty patients (7 to 12 years, with no history of otolaryngological surgery, were evaluated. All of them were submitted to a nasal endoscopy and a lateral cephalometric radiography. In the endoscopic exams it was registered the percentage of nasopharyngeal obstruction and in the radiographic exams it was registered the minor nasopharyngeal dimension. RESULTS: The results of the exams showed a strong correlation with each other (r = - 0.793, p-value < 0.01. After that, reliability tests

    OBJECTIVE: Cystic fibrosis (CF)-related diabetes has been regarded as a mild form of diabetes with a low risk of severe diabetes complications. The prevalence of CF-related diabetes increases with age, resulting in a 50% prevalence of diabetes at age 30 years. We sought to investigate whether...... microvascular complications in CF-related diabetes appear with a relevant frequency. RESEARCH DESIGN AND METHODS: Thirty-eight patients aged 30 (range 18-55) years with CF-related diabetes for 20 (0-31) years were screened for diabetes complications. Because of chronic pulmonary infections, the majority...... of diabetic retinopathy was found in patients with insulin-treated CF-related diabetes, stressing the need for a regular screening program as in type 1 diabetes. Severely impaired kidney function was common in lung transplant patients, probably secondary to cyclosporine treatment....

    Full Text Available Introduction: Adenotonsillectomy is one of the most common surgeries in children, which may be associated with a risk of recurrence of the related symptoms. The aim of this study was to determine the prevalence and possible predisposing and associated factors of adenoid regrowth in children under 15 years old in Besat Hospital in Hamadan. Methods: In this analytic-descriptive study, all the patients less than 15 years old who underwent adenoidectomy or adenotonsillectomy in Besat Hospital in Hamadan City between 2010 and 2016 were reviewed. The charts of the patients underwent revision adenoidectomy were evaluated and their demographic data, clinical findings such as recurrence symptoms, history of allergy, reflux, and the time interval between the first and second surgeries, and the predisposing and associated factors of adenoid hypertrophy recurrence were recorded. The data were analyzed using descriptive statistics with SPSS 16 software. Results: From a total of 2787 patients with adenoidectomy (2571 cases with adenotonsillectomy, 37 cases (1.3% underwent revision adenoidectomy. Of 37 revision adenoidectomies, 48.65% were in females and 51.35% e in males. The mean age at the primary adenoidectomy was 5.16 and at the secondary (revision adenoidectomy was 9.04 years. The mean of interval was 3.87 years between the surgeries. Also, 27% of the patients were passive smoker, 18.9% had a history of reflux and 10.8% had a history of allergic rhinitis. The most common chief complaints of the adenoid regrowth were snoring (35.1% and mouth breathing (25.9%. Conclusion: According to the results of the present study, adenoid re-growth in children under 15 years is not common (1.3% and the predisposing factors of adenoid hypertrophy recurrence were passive smoking, reflux and allergic rhinitis, respectively. It is recommended that nasopharyngeal endoscopy be performed after the adenoid surgery.

    This review highlights recently published data on the pathophysiology, guidelines and treatment of cystic fibrosis (CF)-related bone disease. The exact role of the cystic fibrosis transmembrane conductance regulator (CFTR), specifically the ΔF508 allele, has been investigated in F508del-CFTR homozygous mice and the F508del-CFTR mutation may contribute to CF-related bone disease by slowing new bone formation. The European Cystic Fibrosis Society has issued guidelines for bone mineral density assessment, management of low-trauma fractures and bisphosphonate therapy. A systematic review based on meta-analyses reports that oral and intravenous bisphosphonates both improve bone mineral density in CF patients, but no data are available concerning the reduction of low-trauma fractures. European Cystic Fibrosis Society guidelines may help physicians to improve the management of CF-related bone disease.

    To review disorders that are associated with renal cystic disease during prenatal life and to highlight the strong association between renal cystic disease and ciliopathies. There are numerous causative genes for ciliopathies that can present with cystic kidney disease. In the group of single gene ciliopathies, autosomal dominant polycystic kidney disease is by far the most prevalent one. Other examples are autosomal recessive polycystic kidney disease, nephronophthisis, Bardet-Biedl syndrome, Meckel-Gruber syndrome, Joubert syndrome and related disorders as well as X-linked orofaciodigital syndrome type 1, respectively. The prevalence of these inherited disorders sums up to about in 1 : 2000 people. These disorders with their hepatorenal fibrocystic character should be classified as multisystem diseases. Understanding of the origin of renal cystic disease and associated disorders is important to make the appropriate prenatal diagnosis and for counseling affected parents. In the future, understanding of the pathophysiology may help to develop new treatment strategies.

    2016-01-01

    Although most cystic pancreatic lesions are pseudocysts, it is important to do a thorough differential diagnosis with true cystic tumors because cystic tumors are potentially malignant. Sometimes computed tomography and magnetic resonance imaging cannot establish the definitive diagnosis, making it necessary to perform other imaging tests such as endoscopic ultrasound, which in addition to morphological information, can also enable cytologic and biochemical analysis of the lesion through puncture and aspiration of its contents. Combining all these findings nearly always provides enough diagnostic information to allow the appropriate approach in each case. This article describes the specific morphological characteristics for each cystic pancreatic tumor on computed tomography, magnetic resonance imaging, and endoscopic ultrasound and reviews the guidelines for managing these types of lesions.

    The optimum treatment for cystic vestibular schwannoma (VS) remains controversial. Anecdotally, many treating physicians feel that cystic VSs do not respond to stereotactic radiosurgery (SRS) as well as noncystic tumors. To present outcomes after treatment of predominantly cystic VS with SRS. A prospectively maintained clinical database of patients undergoing Gamma Knife (Elekta Instruments, Stockholm, Sweden) radiosurgery (GKRS) for VS at a single tertiary academic referral center was retrospectively reviewed. Patients diagnosed with cystic VS who were treated with GKRS between 1997 and 2014 were analyzed. Size-matched solid tumors treated with GKRS during this period were selected as controls. Twenty patients (12 women; median age at treatment, 56 years; range, 36-85 years) with cystic VS met inclusion criteria. The median radiologic follow-up within the cystic group was 63 months (range, 17-201 months), and the median change in tumor size was -4.9 mm (range, -10.4 to 9.3 mm). Sixteen tumors (80%) shrank, 2 (10%) remained stable, and 2 (10%) enlarged, accounting for a tumor control rate of 90%. The median radiologic follow-up in the noncystic control group was 67 months (range, 6-141 months), and the median change in size was -2.0 mm (range, -10.4 to 2.5 mm). Tumor control in the solid group was 90%. Comparing only those tumors that decreased in size showed that there was a trend toward a greater reduction within the cystic group ( P = .05). The present study demonstrates that tumor control after SRS for cystic VS may not differ from that of noncystic VS in selected cases.

    Multiple cysts in both hemispheres were detected in four children under 1 year of age by real-time sonographic sector scanning. These cysts, typical of multiple cystic encephalomalacia, followed viral encephalitis in two, bacterial meningitis in one, and bacterial meningitis superimposed on intracerebral hemorrhage in one. The diagnosis of multiple cystic encephalomalacia, which has a grave prognosis, is readily made with high-resolution real-time sonography.

    Cystic changes are common in both neoplastic and non-neoplastic kidney diseases. The most important diagnostic consideration is to rule out cystic neoplasms and hereditary polycystic kidney disease for patient management. Localized cystic disease of the kidney is a rare, nongenetic and nonprogressive cystic disease that may mimic cystic neoplasms or hereditary polycystic disease. However, reports in the literature on its pathologic characteristics are scarce, and most surgical pathologists are unfamiliar with this entity. We report the clinicopathologic characteristics of 9 such cases that mimicked renal neoplasms and were treated surgically. Nine patients, including 5 men and 4 women, had a mean age of 33.3 years (range, 18 to 56 y) at diagnosis. Two patients presented with gross hematuria. In the remaining 7 patients, localized cystic disease was discovered incidentally. None had a personal history of cystic disease of the kidney or other organs or a family history of cystic renal disease. On imaging studies, solitary multilocular cystic lesions were identified in all patients with a mean size of 2.9 cm (range, 0.8 to 6 cm). Of 7 patients with documented Bosniak classification, 4 lesions were class III, and 3 lesions were class II. Follow-up was available in 5 patients, with a mean follow-up time of 14.6 months (range, 5 to 31 mo). No cysts were observed in the ipsilateral and contralateral kidneys during follow-up. Partial and total nephrectomy was performed in 8 and 1 patient, respectively. Grossly, the cystic lesions were not discrete and merged imperceptibly with the adjacent renal parenchyma without a discrete margin or capsule. Microscopically, cystic lesions involved renal papillae in all cases, and the cystic space was continuous with dilated collecting ducts. Cysts were lined with cuboidal or flat epithelial cells identical to those lining the collecting ducts. Significant inflammation was absent. The surrounding renal parenchyma was normal. With this

  9. Classification of nutritional status in cystic fibrosis.

    2006-11-01

    Nutritional status impacts on the progression of cystic fibrosis. Current guidelines recommend the use of anthropometric indicators to classify nutritional status and identify malnutrition. However, the current nutrition-classification systems are problematic. I summarize these problems and review recent progress in the development of evidence-based anthropometric criteria for classifying nutritional status in cystic fibrosis patients. Percentage of ideal body weight as a malnutrition index is flawed. In children with cystic fibrosis, this index underestimates the severity of underweight in short patients and overestimates it in tall patients. In adults with cystic fibrosis, percentage of ideal body weight based on the Metropolitan Life Insurance reference weights for medium/large frames overestimates the severity of underweight. Body-mass-index percentile for children and body mass index for adults as underweight indices have been proven to be valid. Strong associations between body mass index and lung function are also observed, but cutoff values to maintain a desirable level of lung function can vary. Body mass index should replace the use of percentage of ideal body weight for classifying underweight in cystic fibrosis patients. More research is needed to identify appropriate indicators to classify short stature in children with cystic fibrosis.

    Full Text Available Background. Carcinoma of the gallbladder is a tumour with a dismal prognosis and 5-years overall survival rate less than 5%. Among the tumours of the gastrointestinal tract it is fifth in the row and its incidence is approximately 1.2/105. Tumour occurs more often (2–6 times in women and in people over 50 years old (90%. According to the Slovenian Registry of Cancer for year 1998 the incidence of gallbladder carcinoma was 2.7/105 and it occurred 4 times more often among women. The most important risk factors for development of gallbladder carcinoma are: bile stones, chronic inflammation and polyps of the gallbladder. Carcinoma of the gallbladder develops in only 2–3% of the patients with bile stones. When discovered, carcinoma has already invaded the liver in 60%, regional lymph nodes in 45% and the other surrounding organs in 40%. Carcinoma is at time of diagnosis already disseminated in distant organs in 20%. Only in 10% of the patients it is confined to the gallbladder wall. Before the routine use of the ultrasound, computed tomography and tumour markers the disease was discovered preoperatively in 10% versus 90% today. Diagnostic percutaneous biopsy is not recommended. TNM classification and staging of the disease is important for the decision of the modality of treatment.Conclusions. For TNM stage I gallbladder carcinoma, simple cholecystectomy is sufficient. When stage II-IVa is discovered, »en block« resection of gallbladder, liver segments 4b and 5, common bile duct and thorough lymphadenectomy is recommended. Regional radiotherapy and intraarterial chemotherapy with Mitomycin-C are showing promising results. Longterm outcome in patients with gallbladder carcinoma is improving but it is still disappointing.

    Monocyte/macrophage cells from human nasopharyngeal lymphoid tissue can be a source of bacteria responsible for human chronic and recurrent upper respiratory tract infection. Detection and characterization of pathogens surviving intracellularly could be a key element in bacteriological diagnosis of the infections as well as in the study on interactions between bacteria and their host. The present study was undertaken to assess the possibility of isolation of viable bacteria from the cells expressing monocyte/macrophage marker CD14 in nasopharyngeal lymphoid tissue. Overall, 74 adenotonsillectomy specimens (adenoids and tonsils) from 37 children with adenoid hypertrophy and recurrent infections as well as 15 specimens from nine children with adenoid hypertrophy, which do not suffer from upper respiratory tract infections (the control group), were studied. The suitability of immunomagnetic separation for extraction of CD14(+) cells from lymphoid tissue and for further isolation of the intracellular pathogens has been shown. The coexistence of living pathogens including Haemophilus influenzae, Staphylococcus aureus, and Streptococcus pyogenes with the bacteria representing normal nasopharyngeal microbiota inside CD14(+) cells was demonstrated. Twenty-four strains of these pathogens from 32.4 % of the lysates of CD14(+) cells were isolated. Concurrently, the fluorescent in situ hybridization (FISH) with a universal EUB388, and the species-specific probes demonstrated twice more often the persistence of these bacterial species in the lysates of CD14(+) cells than conventional culture. Although the FISH technique appears to be more sensitive than traditional culture in the intracellular bacteria identification, the doubts on whether the bacteria are alive, and therefore, pathogenic would still exist without the strain cultivation.

    We investigated the ultrasonographic (US) appearance of metapIastic squamous breast carcinoma with the pathologic correlation. During an 8-year period, the US appearances of 10 patients with metaplastic squamous breast carcinoma were retrospectively analyzed on the basis of the Breast Imaging and Reporting Data System (BI-RADS) - US lexicon. These 10 patients included 9 patients having invasive adenocarcinomas of the breast with more than 30% squamous metaplasia, and one patient had pure primary squamous cell carcinoma. We correlated the US findings with the pathologic findings. On US, the majority of the tumors showed ovaI shapes (70%), indistinct margins (50%), parallel orientation (80%), echogenic halos (60%), complex echogenicity with solid and cystic components (60%), and posterior enhancement (70%). The findings of calcifications (20%) and metastatic axillary lymph nodes (10%) were rare. On pathologic examination, half of the tumors showed infiltrative microscopic margins. All six cases showing complex echogenicity with solid and cystic components on US were pathologically related to the cystic or necrotic portion, and three of these cases had hemorrhage. On US, metapIastic squamous breast carcinoma mainly manifested as oval, complex, echoic masses with indistinct margins and posterior enhancement that was pathologically related to the cystic or necrotic portions.

    A spectrum of invasive adenocarcinomas presumably arising from the anogenital mammary-like glands of the vulva has been reported. Even rarer are the cases of pure ductal carcinoma in situ that originated from these unique glandular structures. Herein, we report an 81-yr-old woman presented with an invasive well-differentiated squamous cell carcinoma of the vulva. Unexpectedly, the underlying dermis demonstrated a cystically dilated structure that displayed a layer of malignant squamous cells in the periphery, and a second centrally located population of neoplastic cells exhibiting glandular differentiation. In addition, a spindle and pleomorphic malignant cell population consistent with a sarcomatoid carcinoma was identified around the cystic structure. Scattered benign anogenital mammary-like glands were present in the adjacent dermis. The histologic and immunohistochemical findings were consistent with those of vulvar squamous cell carcinoma that has undergone sarcomatoid transformation after spreading in a pagetoid fashion into an underlying focus of ductal carcinoma in situ of anogenital mammary-like gland origin.

    The antibiotic treatment of chest infections which characterise cystic fibrosis (CF) has significantly improved prospects for people with CF. The nature of organisms causing these infections has restricted antibiotic choice. Pseudomonas aeruginosa, especially, is resistant to most oral antibiotics. There is evidence from the laboratory and from other disease processes that macrolide antibiotics, whilst not directly active against Pseudomonas aeruginosa, may have indirect actions against this organism. We aimed to test the hypotheses that macrolide antibiotics:(1) improve clinical status compared to placebo or another antibiotic;(2) have no unacceptable adverse effects. If benefit was demonstrated, we aimed to assess the optimal type, dose and duration of macrolide therapy. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group trials register comprising references identified from comprehensive electronic database searches, handsearching relevant journals and abstract books of conference proceedings.We contacted principal investigators known to work in the field, previous authors and pharmaceutical companies who manufacture macrolide antibiotics for unpublished or follow-up data (December 2002). Date of the most recent search of the Group's register: March 2003. Published or unpublished randomised controlled trials of macrolide antibiotics compared to placebo, another class of antibiotic or another macrolide antibiotic. Studies comparing regimens of the same macrolide antibiotic at different doses will also be included. Two reviewers independently extracted data and assessed study quality. Two groups were contacted for missing data, but these were unavailable for the review. Searches identified eleven studies, two were included in this review (101 participants). One study enrolled adults and the other children (a significant number of whom were not colonised with Pseudomonas aeruginosa). Both studies report small but significant changes in respiratory

    Cystic fibrosis airways are frequently colonised with fungi. However, the interaction of these fungi with immune cells and the clinical relevance in cystic fibrosis lung disease are incompletely understood.We characterised granulocytes in airway fluids and peripheral blood from cystic fibrosis patients with and without fungal colonisation, non-cystic fibrosis disease controls and healthy control subjects cross-sectionally and longitudinally and correlated these findings with lung function parameters.Cystic fibrosis patients with chronic fungal colonisation by Aspergillus fumigatus were characterised by an accumulation of a distinct granulocyte subset, expressing the HIV coreceptor CXCR4. Percentages of airway CXCR4(+) granulocytes correlated with lung disease severity in patients with cystic fibrosis.These studies demonstrate that chronic fungal colonisation with A. fumigatus in cystic fibrosis patients is associated with CXCR4(+) airway granulocytes, which may serve as a potential biomarker and therapeutic target in fungal cystic fibrosis lung disease.

  1. Markers of metastatic carcinoma of breast origin.

    Science.gov (United States)

    Gown, Allen M; Fulton, Regan S; Kandalaft, Patricia L

    2016-01-01

    This review summarizes the three major breast-associated markers that can be of assistance in evaluating metastatic carcinomas for which a breast primary diagnosis is entertained. These markers include gross cystic disease fluid protein-15 (GCDFP-15), mammaglobin, and GATA3. The first two are cytoplasmic markers that show comparable sensitivities for breast cancer, although relatively few of the published studies have employed the same antibodies against the target molecule, making direct comparisons challenging. GATA3 is a nuclear transcription factor that shows superior sensitivity to GCDFP-15 and mammaglobin. However, the specificity of GATA3 can pose challenges, inasmuch as carcinomas of the bladder and other sites can show significant levels of positivity. Determination of the optimal panel of antibodies employed in a given clinical setting will thus depend on the non-breast tumours included in the differential diagnosis. © 2015 John Wiley & Sons Ltd.

    Infertility rates among males with cystic fibrosis (CF) approximate 97%. No information is currently available within Ireland determining an understanding of fertility issues and the best methods of information provision to this specialized group. This study aimed to determine understanding and preferred approaches to information provision on fertility issues to Irish CF males. A Descriptive Study utilizing prospective coded questionnaires was mailed to a male CF cohort (n=50). Sections included demographics, fertility knowledge & investigation. Response rate was 16\\/50 (32%). All were aware that CF affected their fertility. More than two-thirds (n=11) were able to provide explanations whilst only one-third (n=5) provided the correct explanation. Significant numbers stated thoughts of marriage and a future family. Half have discussed fertility with a healthcare professional (HCP). Mean age of discussion was 21.9 years. One third preferred an earlier discussion. The commonest first source for information was written material which was also the preferred source. Three-quarters requested further information preferring again, written material. Significant gaps in sex education of Irish CF males exist. Discussion should be initiated by HCPs and centre-directed written material devised to address deficiencies.

  3. Cystic fibrosis: a clinical view.

    Cystic fibrosis (CF), a monogenic disease caused by mutations in the CFTR gene on chromosome 7, is complex and greatly variable in clinical expression. Airways, pancreas, male genital system, intestine, liver, bone, and kidney are involved. The lack of CFTR or its impaired function causes fat malabsorption and chronic pulmonary infections leading to bronchiectasis and progressive lung damage. Previously considered lethal in infancy and childhood, CF has now attained median survivals of 50 years of age, mainly thanks to the early diagnosis through neonatal screening, recognition of mild forms, and an aggressive therapeutic attitude. Classical treatment includes pancreatic enzyme replacement, respiratory physiotherapy, mucolitics, and aggressive antibiotic therapy. A significant proportion of patients with severe symptoms still requires lung or, less frequently, liver transplantation. The great number of mutations and their diverse effects on the CFTR protein account only partially for CF clinical variability, and modifier genes have a role in modulating the clinical expression of the disease. Despite the increasing understanding of CFTR functioning, several aspects of CF need still to be clarified, e.g., the worse outcome in females, the risk of malignancies, the pathophysiology, and best treatment of comorbidities, such as CF-related diabetes or CF-related bone disorder. Research is focusing on new drugs restoring CFTR function, some already available and with good clinical impact, others showing promising preliminary results that need to be confirmed in phase III clinical trials.

    Over the past 20 years there has been a greater interest in infection control in cystic fibrosis (CF) as patient-to-patient transmission of pathogens has been increasingly demonstrated in this unique patient population. The CF Foundation sponsored a consensus conference to craft recommendations for infection control practices for CF care providers. This review provides a summary of the literature addressing infection control in CF. Burkholderia cepacia complex, Pseudomonas aeruginosa, and Staphylococcus aureus have all been shown to spread between patients with CF. Standard precautions, transmission-based precautions including contact and droplet precautions, appropriate hand hygiene for health care workers, patients, and their families, and care of respiratory tract equipment to prevent the transmission of infectious agents serve as the foundations of infection control and prevent the acquisition of potential pathogens by patients with CF. The respiratory secretions of all CF patients potentially harbor clinically and epidemiologically important microorganisms, even if they have not yet been detected in cultures from the respiratory tract. CF patients should be educated to contain their secretions and maintain a distance of >3 ft from other CF patients to avoid the transmission of potential pathogens, even if culture results are unavailable or negative. To prevent the acquisition of pathogens from respiratory therapy equipment used in health care settings as well as in the home, such equipment should be cleaned and disinfected. It will be critical to measure the dissemination, implementation, and potential impact of these guidelines to monitor changes in practice and reduction in infections.

  5. Evaluation of hepatic cystic lesions

    2013-01-01

    Hepatic cysts are increasingly found as a mere coincidence on abdominal imaging techniques, such as ultrasonography (USG), computed tomography (CT) and magnetic resonance imaging (MRI). These cysts often present a diagnostic challenge. Therefore, we performed a review of the recent literature and developed an evidence-based diagnostic algorithm to guide clinicians in characterising these lesions. Simple cysts are the most common cystic liver disease, and diagnosis is based on typical USG characteristics. Serodiagnostic tests and microbubble contrast-enhanced ultrasound (CEUS) are invaluable in differentiating complicated cysts, echinococcosis and cystadenoma/cystadenocarcinoma when USG, CT and MRI show ambiguous findings. Therefore, serodiagnostic tests and CEUS reduce the need for invasive procedures. Polycystic liver disease (PLD) is arbitrarily defined as the presence of > 20 liver cysts and can present as two distinct genetic disorders: autosomal dominant polycystic kidney disease (ADPKD) and autosomal dominant polycystic liver disease (PCLD). Although genetic testing for ADPKD and PCLD is possible, it is rarely performed because it does not affect the therapeutic management of PLD. USG screening of the liver and both kidneys combined with extensive family history taking are the cornerstone of diagnostic decision making in PLD. In conclusion, an amalgamation of these recent advances results in a diagnostic algorithm that facilitates evidence-based clinical decision making. PMID:23801855

    Cystic fibrosis (CF) is an autosomal recessive genetic disease that occurs in approximately 1 in 2,500 white live births. It is less common in nonwhite individuals. A dysfunctional epithelial chloride channel leads to excessively thick mucus affecting multiple organ systems. Common issues include mucous plugging of the airway, lung inflammation, chronic pulmonary infections, intestinal malabsorption, and malnutrition. Universal screening of newborns for CF is recommended in many countries. CF can be diagnosed based on clinical evidence of disease along with genetic testing or other laboratory evidence of chloride channel dysfunction. Pulmonary system dysfunction causes the most morbidity and mortality. Pulmonary function testing is the primary modality used to monitor CF progression. Therapies include chest physiotherapy, mucolytics, antibiotics, anti-inflammatory drugs, targeted therapies, and vaccines. Dysfunction of the exocrine pancreas and gastrointestinal tract leads to malabsorption, malnutrition, and intestinal obstruction. Nutrition should be optimized with adequate calories, pancreatic enzymes, and appropriate dietary supplements. Complications, including acute pulmonary exacerbations, gastrointestinal conditions, chronic rhinosinusitis, CF-related diabetes, osteoporosis, infertility, and psychosocial issues, must be managed. At the appropriate time, lung transplantation and end-of-life issues must be addressed.

    To investigate the feasibility of magnetization transfer contrast (MTC) in characterization of pelvic cystic masses and ascites, in vitro studies were performed. Cystic fluids were taken from operative specimens of ten ovarian cystic masses (five mucinous cystadenomas, one cystadenocarcinoma, two serous cystadenocarcinomas, two clear cell carcinomas) and three non-ovarian pelvic cysts (one paraovarian cyst, one pseudomyxoma peritonei, one pelvic abscess). Samples of ascitic flied were drawn by peritoneal puncture in twenty patients (thirteen with peritonitis carcinomatosa, five with liver dysfunction, two with renal dysfunction). Total protein content in ascitic fluids was measured. Magnetization transfer ratio (MTR) was calculated by the signal intensities under the gradient echo sequence with and without the application of off-resonance pulses. The relative signal intensities (RSI) relative to water in T{sub 1} and T{sub 2} weighted images were obtained using spin echo sequence. There was no correlation between histological type of pelvic mass and MTR and RSI. Good correlation (R{sup 2}=0.761) was obtained between MTR and protein content in ascitic fluids, whereas no correlation was noted between RSI and protein content in ascitic fluids. These results suggest that MTC is not useful in the characterization of pelvic masses but is applicable in the differentiation between exudative ascites and transudative ascites. (author)

    Amyloid-associated cystic lung disease is rare. It can be associated with collagen vascular disease (CVD). We aimed to describe the clinical, radiology, and pathology findings of this entity. We reviewed the records of subjects having biopsy-proven pulmonary amyloidosis with cystic lung disease demonstrated at high-resolution computed tomography (HRCT). Demographic characteristics, association with CVD and lymphoproliferative disorders, pulmonary function, and pathology results were reviewed. HRCT appearance was analyzed for number, size, distribution, and morphology of cysts and nodules. Twenty-one subjects (13 female, eight male; median age, 61 years) with cystic pulmonary amyloidosis were identified. The most common pulmonary function patterns were normal (42%) and obstructive (32%). The most common associated CVD was Sjögren syndrome (10 of 12). Nine subjects had no CVD. Cysts tended to be multiple (≥ 10 in 14 of 21, 67%), round (21 of 21, 100%), or lobulated (20 of 21, 95%); thin-walled (cystic lung disease can occur with or without underlying CVD. Cystic lesions in the lung are commonly numerous, often are peribronchovascular or subpleural, and are frequently associated with nodular lesions that are often calcified. MALToma was a relatively frequent association. Copyright © 2016 American College of Chest Physicians. Published by Elsevier Inc. All rights reserved.

    Improvements in the sensitivity and quality of cross-sectional imaging have led to increasing numbers of patients being diagnosed with cystic lesions of the pancreas. In parallel, clinical, radiological, pathological and molecular studies have improved the systems for classifying these cysts. Patients with asymptomatic serous cystic neoplasms can be managed conservatively with regular monitoring; however, the clinical management of patients with intraductal papillary mucinous neoplasms and mucinous cystic neoplasms is far more challenging, as it is difficult to determine whether these lesions will progress to malignancy. Fortunately, prospective studies have helped to establish that proposed clinical and radiological criteria (the Sendai guidelines) can be used to guide the care of patients with cystic lesions of the pancreas. Despite this progress in imaging and clinical guidelines, sensitive and specific tests have not yet been developed that can reliably predict the histology and biological properties of a cystic lesion. Such biomarkers are urgently needed, as noninvasive precursors of pancreatic cancer are curable, while the vast majority of invasive pancreatic adenocarcinomas are not. PMID:21383670

    The purpose of this study was to clarify the relationships between upper airway factors (nasal resistance, adenoids, tonsils, and tongue posture) and maxillofacial forms in Class II and III children. Sixty-four subjects (mean age, 9.3 years) with malocclusion were divided into Class II and Class III groups by ANB angles. Nasal resistance was calculated using computational fluid dynamics from cone-beam computed tomography data. Adenoids, tonsils, and tongue posture were evaluated in the cone-beam computed tomography images. The groups were compared using Mann-Whitney U tests and Student t tests. The Spearman rank correlations test assessed the relationships between the upper airway factors and maxillofacial form. Nasal resistance of the Class II group was significantly larger than that of the Class III group (P = 0.005). Nasal resistance of the Class II group was significantly correlated with inferior tongue posture (P Class III group was significantly correlated with anterior tongue posture (P Class III group was significantly correlated with mandibular protrusion. The relationships of upper airway factors differ between Class II and Class III children. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

    Full Text Available Introduction. The quality of our life is determined by the quality of the air that we breathe. Hence the influence of cigarette smoking and secondary exposure of persons within the smoking environment is significant. Previous studies have confirmed the influence of passive smoking to on the accumulation of given elements in the tonsils. The subject of the study is to determine the importance of ETS exposure for the accumulation of Pb, Be, Ba, Ca, Mg and Sr in the pharyngeal tonsils. Material and methods. The study involved 162 adenoids from boys and girls living in Tychy and Chorzów. exposed and not exposed to passive smoking. All biological samples were subjected to mineralization with nitric acid (V from Merck. The chemical composition of the samples was determined by the ICP – AES method. Results. The statistical analysis of the elements in the tonsils of children exposed and not exposed to ETS is performed taking into account as an additional criterion of distribution the place of residence and gender of the children. Conclusions. There was no significant effect of passive smoking on the increase of the examined metals in the adenoid. However the role of gender and place of residence to the process of accumulation of elements in this organ remains significant.

    Full Text Available Ameloblastoma of jaws are common and locally destructive tumors originating from odontogenic apparatus. They constitute approximately 1% of all jaw tumors with 80% occurring in the mandible. Ameloblastoma exhibiting a frank malignancy is a rare entity and occurs in less than 1% of all ameloblastomas. Among the two jaws, ameloblastic carcinoma involving maxilla is extremely rare with only few cases reported so far in the literature. Here we report two cases of ameloblastic carcinoma one involving the maxilla and the other involving mandible, with an aggressive clinical course leading to extensive local destruction of the affected jaws.

    This review highlights the changes that have occurred in the general approach to cystic renal diseases in children. For instance, genetic mutations at the level of the primary cilia are considered as the origin of many renal cystic diseases. Furthermore, these diseases are now included in the spectrum of the hepato-renal fibrocystic diseases. Imaging plays an important role as it helps to detect and characterize many of the cystic diseases based on a detailed sonographic analysis. The diagnosis can be achieved during fetal life or after birth. Hyperechoic kidneys and/or renal cysts are the main sonographic signs leading to such diagnosis. US is able to differentiate between recessive and dominant polycystic kidney diseases, hepatocyte nuclear factor 1 Beta mutation, glomerulocystic kidneys and nephronophtisis. MR imaging can, in selected cases, provide additional information including the progressive associated hepatic changes. (orig.)

It generallyaffects young adults in the third to fourth decades, with no genderpredilection. Computerized tomography images revealed importantcharacteristics that were not detected by panoramic radiography,such as fenestration, calcification and tooth-like structures. Thetypical microscopic feature of this lesion is the presence of variableamounts of aberrant epithelial cells, without nuclei, which arenamed “ghost cells”. In addition, dysplastic dentine can be foundand occasionally the cyst can be associated with an area of dentalhard tissue formation resembling an odontoma. The treatment forcalcifying cystic odontogenic tumor involves simple enucleationand curettage.

As the median survival has increased related to early multidisciplinary intervention, other manifestations of CF have emergedespecially for the broad spectrum of hepatobiliary involvement. The present study reviews the existing literature on liver disease in cystic fibrosis and describes the key issues for an adequate clinical evaluation and management of patients, with a focus on the pathogenetic, clinical and diagnostic-therapeutic aspects of liver disease in CF. Evidence Acquisition A literature search of electronic databases was undertaken for relevant studies published from 1990 about liver disease in cystic fibrosis. The databases searched were: EMBASE, PubMed and Cochrane Library. Results CF is due to mutations in the gene on chromosome 7 that encodes an amino acidic polypeptide named CFTR (cystic fibrosis transmembrane regulator).

    The aim of this retrospective, population-based study was to characterize demographically and clinically cystic-echinococcosis (CE) in southern Israel, between 2005 and 2012. Newly-diagnosed (nd-CE) and past-diagnosed (pd-CE, diagnosed before the study) cases were defined. Two populations live in southern-Israel, receiving medical treatment at a single hospital: the Jewish and the Bedouin populations (resembling resource-rich and resource-poor populations, respectively). 126 CE cases were identified; 55 nd-CE and 71 pd-CE. Mean annual nd-CE incidence per 100,000 in the Bedouin and Jewish populations were 2.7 ± 1.2 and 0.4 ± 0.3, respectively (PIsrael. Liver and lung involvement were recorded in 85.7% and 15.1% of overall-CE, respectively. Abdominal pain, cough, fever, eosinophilia and asymptomatic disease were documented in 63.6%, 32.7%, 27.3%, 41.5% and 12.7% of nd-CE, respectively. Serology sensitivity for first test and any positive test were 67.3% and 83.3%, respectively. Computed tomography, ultrasonography and X-ray diagnosis were documented in 79.2%, 58.4% and 17.0% of overall-CE, respectively, with ultrasonography mainly used in liver-CE and X-ray in lung-CE. Treatment included surgery and albendazole in 50.0% and 55.3% of CE, respectively. We conclude that CE is endemic in southern-Israel among the Bedouin population, while disease is probably mainly imported in the Jewish population. Liver involvement and eosinophilia rates were high compared with those of other endemic regions, possibly due to differences in the timing of diagnosis. These findings may help developing treatment and prevention strategies.

    Abstract Background: Cystic angiomatosis (CA) is a rare disorder causing bony cysts. It displays some similarity to Gorham–Stout disease (GSD), but has a much better local prognosis, despite the larger number of cysts. These 2 conditions also differ in terms of their location, visceral involvement, and response to treatment. Methods: We report 4 cases of CA, including 1 sclerosing form, which we compare with cases from a literature review performed with PRISMA methodology. Results: We reviewed 38 articles describing 44 other patients. Mean age at diagnosis for the 48 patients (our 4 patients + the 44 from the review) was 22.5 years, and 28 of the patients were men. The femur was involved in 81% (n = 39), the pelvis in 73% (n = 35), the humerus in 52% (n = 25), the skull in 48% (n = 23), and the vertebrae in 44% (n = 21). Visceral lymphangiomatosis (either clinical, or detected on autopsy) was also reported in 35% (n = 18) of the patients. The spleen was the most frequently involved organ (n = 12), followed by the lungs and pleura (n = 8). Liver cysts and/or chylothorax were rarely reported (5 cases), but were invariably fatal. Radiation therapy on bone or soft tissue masses was ineffective, as was interferon alpha, in the 2 patients in which this drug was tested. The efficacy of bisphosphonate was at best equivocal. Conclusion: The progression of CA is unpredictable and treatments effective against GSD, such as bisphosphonates and radiotherapy, have proved ineffective for this condition. New treatments are thus urgently required. PMID:27787381

    Full Text Available Abstract Nasopharyngeal carcinoma (NPC is a tumor arising from the epithelial cells that cover the surface and line the nasopharynx. The annual incidence of NPC in the UK is 0.3 per million at age 0–14 years, and 1 to 2 per million at age 15–19 years. Incidence is higher in the Chinese and Tunisian populations. Although rare, NPC accounts for about one third of childhood nasopharyngeal neoplasms. Three subtypes of NPC are recognized in the World Health Organization (WHO classification: 1 squamous cell carcinoma, typically found in the older adult population; 2 non-keratinizing carcinoma; 3 undifferentiated carcinoma. The tumor can extend within or out of the nasopharynx to the other lateral wall and/or posterosuperiorly to the base of the skull or the palate, nasal cavity or oropharynx. It then typically metastases to cervical lymph nodes. Cervical lymphadenopathy is the initial presentation in many patients, and the diagnosis of NPC is often made by lymph node biopsy. Symptoms related to the primary tumor include trismus, pain, otitis media, nasal regurgitation due to paresis of the soft palate, hearing loss and cranial nerve palsies. Larger growths may produce nasal obstruction or bleeding and a "nasal twang". Etiological factors include Epstein-Barr virus (EBV, genetic susceptibility and consumption of food with possible carcinogens – volatile nitrosamines. The recommended treatment schedule consists of three courses of neoadjuvant chemotherapy, irradiation, and adjuvant interferon (IFN-beta therapy.

    Full Text Available Hydatic cyst is an illness that appears in consequence of the cystic form of small strap-shaped worm Echinococcus granulosis. Frequently, cysts exist in the lungs and liver. Peritoneal involvement is rare, and generally occurs as a result of second inoculation from rupture of a liver-located hydatic cyst. Primary ovarian hydatic cyst is very rare. A 56-year-old female patient was admitted to Emergency Service with the complaint of stomachache and swollen abdomen. From ultrasonographic examination, a right ovarian 52 × 45-mm heterogeneous semi-solid cystic mass and right hydronephrosis were detected. As a result of the tomographic examination, the right ovarian growth was judged to be a 60 × 45-mm lobule contoured, septal, heterogeneously cystic mass (ovarian carcinoma. Depending on these indicators and with the diagnosis of ovarian carcinoma, laparotomy was planned. During the observation, a mass that compressed on the right ureter and dilatation in the right ureter were determined. The mass was approximately 6 cm long and smoothly contoured, including widespread adhesions, and also obliteration of the pouch of Douglas. The mass was excised and total abdominal hysterectomy and bilateral salpingo-oopherectomy performed. After a pathological examination, hydatid cyst was diagnosed. Although pointing at the issue of the distinctive diagnosis of pelvic and peritoneal mass, it should be realized that the existence of primary peritoneal and pelvic involvement of the hydatic cyst is generally a result of the second inoculation, and is also more common in regions in which Echinococcus granulosa is endemic and livestock production is prevalent.

    Purpose: To clarify if the portal venous phase is helpful for the differential diagnosis of groove pancreatic carcinomas and groove pancreatitis. Materials and methods: MDCT and MRI of groove pancreatic carcinomas (n = 7) and groove pancreatitis (n = 15) were retrospectively reviewed by two radiologists independently. The signal intensity on T2-weighted images was subjectively assessed. The presence or absence of common bile duct (CBD) and main pancreatic duct (MPD) strictures, calcifications, and cystic lesions was evaluated. Additionally, the appearance of groove pancreatic carcinoma and that of groove pancreatitis in the portal venous phase on dynamic MDCT and MRI were compared. Results: There were no significant differences in the signal intensity on T2-weighted images and in the presence or absence of CBD and MPD strictures, calcifications, and cystic lesions between groove pancreatic carcinomas and groove pancreatitis. However, patchy focal enhancement in the portal venous phase was more commonly observed in groove pancreatitis than groove pancreatic carcinoma (Reviewers 1 and 2: 14/15 [93.3%] vs. 1/7 [14.3%], P < 0.0001). In addition, peripheral enhancement was only seen in groove pancreatic carcinomas (Reviewer 1: 4/7 [57.1%] vs. 0/15 [0%], P < 0.005, and Reviewer 2: 3/7 [42.9%] vs. 0/15 [0%], P < 0.05). Conclusion: The portal venous phase may be helpful for the differential diagnosis of groove pancreatic carcinomas and groove pancreatitis.

    Retroperitoneal cysts are a rare disease. Most retroperitoneal cysts of vascular origin have been reported as hemangiomas. However, according to the recent classification of vascular anomalies accepted by the International Society for Study of Vascular Anomalies (ISSVA), these previously reported retroperitoneal hemangiomas should rather have been classified as vascular malformations. A 65-year-old woman visited our hospital complaining of a sense of unexplained abdominal fullness. Magnetic resonance imaging suggested a uterine leiomyoma and bilateral ovarian cystic tumors. However, abdominal surgery revealed normal bilateral ovaries, but huge cystic masses in the retroperitoneum. Postoperative histological diagnosis of the retroperitoneal cysts demonstrated that they were venous malformations. This is a rare case in which large cystic retroperitoneal venous malformations were preoperatively diagnosed as ovarian cystic tumors. Retroperitoneal hemangiomas should be renamed as vascular malformations following the ISSVA classification.

    The distinction between ocular sebaceous carcinoma, poorly differentiated ocular squamous cell carcinoma and ocular basal cell carcinoma can be challenging. An appropriate immunohistochemical panel may help to differentiate these lesions. To determine the distribution and use of several immunostains in these specimens, formalin-fixed, paraffin-embedded tissue from several of each was studied using an immunohistochemical technique. Positive staining for cytokeratin (CK)7 was seen in 100% of sebaceous carcinomas, 77.8% of basal cell carcinomas and 67.7% of squamous cell carcinomas. One hundred percent of sebaceous and basal cell carcinomas were positive for cytokeratin CAM 5.2, while only 83.3% of squamous cell carcinomas were positive. Using epithelial membrane antigen (EMA), 100% of squamous cell carcinomas and 80% of sebaceous carcinomas were positive, while basal cell carcinomas were uniformly negative. One hundred percent of basal cell carcinomas and 80% of sebaceous carcinomas were positive for Ber-EP4, while all squamous cell carcinomas were negative. Finally, 77.8%, 20% and 16.7% of basal cell carcinomas, sebaceous carcinomas and squamous cell carcinomas showed immunoreactivity for the androgen receptor. An EMA positive, Ber-EP4 positive immunophenotype supports sebaceous carcinoma, EMA positive, Ber-EP4 negative result supports squamous cell carcinoma and an EMA negative, Ber-EP4 positive result supports basal cell carcinoma.

    Full Text Available Here, we report an extremely rare case of trichoepithelioma (TE—a benign epithelial tumor originating from the outer root sheath of a hair follicle—arising in an ovarian mature cystic teratoma (MCT with fluorodeoxyglucose-positron emission tomography (FDG-PET findings. A 48-year-old Japanese woman presented to our hospital for her annual follow-up of adenomyosis. Ultrasonography and magnetic resonance imaging revealed a left ovarian tumor with irregular-shaped septum, which was suspicious of malignancy. However, tumor marker levels were within normal range. On FDG-PET, the maximum standardized uptake value (SUVmax of the tumor was 2.9. Laparotomy with left salpingooophorectomy was performed. Pathologic examination revealed the probability of TE, rather than basal cell carcinoma (BCC, arising in an ovarian MCT. After five years of follow-up, the patient had no sign of recurrence. The FDG-PET SUVmax was low in TE, as with other benign tumor. However, future investigation is needed to evaluate the findings of FDG-PET imaging in TE cases.

    Acquired cystic kidney disease (ACKD) is a condition that occurs predominantly in patients with end-stage renal disease (ESRD). In contrast to hereditary cystic kidney disease, ACKD is characterized by the presence of multiple small cysts in bilaterally small kidneys. Limited pediatric data suggest a high incidence (21.6-45.8%) of ACKD in children on dialysis, comparable to that in adults, with an increased frequency associated with a longer duration of dialysis. Recent research has shed light on the pathogenesis of ACKD, such as activation of proto-oncogenes. Although most patients with ACKD are asymptomatic, the condition can be complicated by renal cell carcinoma. Routine surveillance should therefore be considered in at-risk populations.

    Lung disease in patients with cystic fibrosis is characterised by inflammation and recurrent and chronic infections leading to progressive loss in pulmonary function and respiratory failure. Early management of disease results in substantially improved pulmonary function at first testing (at roughly 6 years of age), but the annual decline in pulmonary function tests in older patients has remained unchanged showing how important the early years are in the disease process. Treatment regimens for patients with cystic fibrosis have changed from predominantly symptomatic treatment to preventive or causal (ie, treatments that address the underlying mechanisms of disease) therapeutic interventions. The infant and preschool age (2-5 years) could represent a unique period of opportunity to postpone or even prevent the onset of cystic fibrosis lung disease. We summarise the current knowledge and the methods used to characterise and quantify early lung disease. We discuss treatment strategies including new drugs that are being developed and their potential role in the treatment of early lung disease in patients with cystic fibrosis.
