    Full Text Available Introducción. Recientemente han venido aumentando los reportes de dengue hemorrágico con manifestaciones inusuales, principalmente neurológicas y hepáticas, que aumentan la morbimortalidad. Objetivo. Describir las manifestaciones inusuales del dengue hemorrágico en niños. Materiales y métodos. En el Departamento de Pediatría del Hospital Universitario de Santander en Bucaramanga, Colombia, de 913 pacientes con diagnóstico de dengue hemorrágico entre 1992 y 2004, se seleccionaron aquéllos que presentaron manifestaciones inusuales. Se clasificaron de acuerdo con los criterios de definición de caso, se agruparon según los órganos o sistemas principalmente comprometidos y se describieron los principales hallazgos clínicos, de laboratorio y relativos a la evolución. Resultados. Se encontraron 168 pacientes que presentaron manifestaciones inusuales, con predominio del sexo masculino, edad escolar y grados III y IV de dengue hemorrágico. Las manifestaciones más frecuentes fueron hepáticas, 53 (27%, y neurológicas, 49 (25%, además de renales, 14 (7%; cardíacas, 15 (8%; pulmonares, 18 (9%; colecistitis alitiásica, 18 (9%; síndrome hemofagocítico, 5 (2,5%; pancreatitis, 2 (1%, y 21 casos de abdomen agudo (11%. Fallecieron 10 pacientes. Conclusión. Se analizan los resultados y se comparan con otros de países endemoepidémicos de dengue; se discute el significado e importancia de las manifestaciones clínicas inusuales, su difícil diagnóstico, casi siempre en forma retrospectiva, y se destaca la frecuencia de las manifestaciones hepáticas y neurológicas que pueden aumentar la morbimortalidad, ante las cuales deben estar alertas los médicos que trabajan en zonas endémicas para reconocerlas.

    Thyroid carcinoma (TC) is a slow growing tumor with an indolent course and has an excellent prognosis. However, a sharp contrast exists in the biological behavior of TC, which in its well-differentiated form is associated with long-term survival, but in its undifferentiated form is one of the most lethal neoplasms known. The anaplastic carcinoma (ANC) form has a fulminanat course with poor prognosis and almost invariably, a fatal outcome

    Multiple primaries in a single patient are uncommon, though not very rare. The existence of such cancers in two un-related, non-paired organs is even more un-common. Here, we present a case of 55 years old male who presented to us with a mucoepidermoid carcinoma of the parotid gland and was operated. Later on, he presented with a large cystic swelling in the pelvis which turned out to be pseudomyxoma peritonei. A review of slides and immunohistochemistry indicated it to be adenocarcinoma colon. He presented again with recurrent mucoepidermoid carcinoma of the parotid which was operated successfully with the use of myocutaneous flap for wound closure. He is currently undergoing chemotherapy. In order to establish a separate mono-clonal etiology of both tumours, immunohistochemistry was performed. To the best of our knowledge, carcinoma multiplex in the colon and the parotid has never been reported before. (author)

    Follicular thyroid carcinoma (FTC) is considered as a disease of the elderly with a higher incidence in females as compared to papillary thyroid carcinoma (PTC). Some studies have reported its occurrence at an early age, which may be attributed to early diagnosis because of the availability of advanced techniques. The prognosis of the disease is considered poor as compared to that of PTC. The conclusions drawn in this review are based on 663 cases in whom adequate data was available for meaningful analysis followed for a mean period of 9.2 years, median, 7.8 years; range, 1-32 years

    1999-01-01

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

    In this document the case of a 66-year old woman is presented, with record of multi nodular goiter of 5 year of evolution, which is derived to scan ultrasound office to make a puncture-aspiration with thin needle because of the growth of nodular thyroid injuries. The ultrasound scan examination made before the puncture determine multiple dominant nodules of hyperplasia aspect between 15 and 25 mm of diameter and a small nodule of 6 mm suspected proliferate process. Despite its size, it was decided to include small nodule in injuries to a biopsy. The cytological study reveals nodular hyperplasia with carcinoma in the small nodule of 6 mm. A thyroidectomy is practiced on the patient. The deferred histological study of the thyroid gland confirms the finding of multi-nodular goiter with a small focus of papillar carcinoma. The ganglions examined were negative in the deferred examination [es

    Hepatocellular carcinoma (HCC) is a common cause of cancer mortality. Hepatitis B and C viruses, aflatoxin and alga toxin in the contaminated drinking water are the major etiological factors. Rapidly progressing medical imaging has resulted in the improved treatment results. Surgical resection has a major role for influencing prognosis of HCC. Local cancer therapies based on the advances in early diagnosis are progressing rapidly. Multimodality combination and sequential treatment has proved effective, unfortunately systemic chemotherapy for HCC remains disappointed. All of these have resulted in the improved prognosis of HCC.

  19. Carcinoma gallbladder.

    Carcinoma gallbladder (CaGb) is a rare disease. The aetiology of CaGb is yet not known. However the risk of CaGb is increased in anomalous pancreaticobiliary duct junction (APBDJ), gall stones, xanthogranulomatus cholecystitis, calcified or porcelain gallbladder, cholelithiasis with typhoid carriers, gallbladder adenoma, red meat consumption and tobacco uses. There are protective effects of vegetables on CaGb. Most of the cases present with advanced disease. In early carcinoma of a gallbladder sign and symptoms mimic benign disease. The diagnosis is established by ultrasonography, computerized tomography and guided fine needle aspiration cytology (FNAC). Biochemical tests are of very little value in making a diagnosis. The treatment depends on the clinical stage at presentation. Surgery offers the best chance of cure. In stage T1a, laparoscopic or open cholecystectomy alone is curative, and in T1b, cholecystectomy with hepatoduodenal lymph node dissection without combined resection of an adjacent organ is required. Segment S4a+5 hepatectomy combined with extrahepatic bile duct resection (BDR) and D2 lymph node dissection is a highly recommended operation for the treatment of T2 and T3 CaGb. The dye injection method is useful in determining the appropriate extent of hepatic resection for advanced CaGb. Resurgery is required only in those cases where tumour has invaded the serosa and/ or adjacent structures when diagnosed postoperatively. Biliary bypass is required for palliation. Prognosis depends on early diagnosis and appropriate surgical excision.

    1995-01-01

    Purpose: Controversies exist regarding the use of radiation therapy in the treatment of vulvar carcinoma. A retrospective review was performed to evaluate our institution's experience with surgery and radiation for this disease. Methods and Materials: The medical records of 47 patients treated for squamous cell carcinoma of the vulva at our institution (1974-1992) were reviewed for TNM stage (AJCC criteria), treatment modality, and associated 5-year local control and survival based on Kaplan-Meier analysis. Results: Twenty-eight patients (60%) presented with Stage I and II disease and their 5-year survival was 69%. Stage III patients accounted for 12 (25%) of the patients and their 5-year survival was 73%. Seven patients presented with Stage IV disease and five died within 13 months of diagnosis after predominantly palliative therapy. The 40 patients with Stages I, II, and III disease were treated aggressively and were further evaluated for treatment-modality-associated survival and local control. Radiation therapy was used as primary treatment in nine patients, of whom seven were treated with radiation alone and two were treated postoperatively after wide excision. Surgery alone was performed in 31 patients consisting of either radical vulvectomy (20 patients) or wide excision (11 patients). When comparing outcomes of radical vulvectomy vs. radiation therapy, we noted that the 5-year actuarial survivals were comparable (74% for either modality), despite the presence of more favorable prognostic factors in the group treated with radical vulvectomy. Patients treated with wide excision alone had a trend for a poorer 5-year actuarial survival (51%) and local control (50%). Conclusions: Radical vulvectomy offers good locoregional control and survival. This retrospective review further supports the use of radiation therapy with conservative surgery as an alternative treatment option for patients with vulvar carcinoma treated with curative intent. In contrast, the use of

    From June 1993 through October 1996, nineteen oropharynx cancer patients (squamous cell carcinoma T1; 1, T2; 10, T3; 6, T4; 1, and adenocarcinoma T2; 1) were treated with high dose rate interstitial radiotherapy combined with moderate external radiotherapy. Fourteen patients (T1; 1, T2; 10 and T3; 3) were controlled locally and five patients (T3; 3, T4; 1 and adenocarcinoma; 1) were not. Temporary soft tissue necrosis were experienced among four patients. With short follow-up period xerostomia and dysgeusia were less than definitive external radiotherapy as clinical impression. In addition with markedly increased tumor dose the local control rate can be improved. This treatment method can be an alternative to definitive external radiotherapy to gain better QOL and higher control rate. (author)

    Poorly differentiated thyroid carcinoma (PDTC) has been recognized for the past 30 years as an entity showing intermediate differentiation and clinical behavior between well-differentiated thyroid carcinomas (ie, papillary thyroid carcinoma and follicular thyroid carcinoma) and anaplastic thyroid carcinoma; however, there has been considerable controversy around the definition of PDTC. In this review, the evolution in the definition of PDTC, current diagnostic criteria, differential diagnoses, potentially helpful immunohistochemical studies, and molecular alterations are discussed with the aim of highlighting where the diagnosis of PDTC currently stands.

    Radiotherapy of branchogenic carcinoma comprises; palliative treatment, postoperative or pre-operative radiotherapy, radiotherapy as part of a combination of chemotherapy and radiotherapy of small cell carcinoma and curative radiotherapy of non-operable non-small cell carcinoma. Atelectasis and obstruction are indications for palliative radiotherapy. Postoperative radiotherapy is given only in cases of incomplete resection or mediastinal metastases. In the treatment of small cell carcinoma by combined irradiation and chemotherapy the mediastinum and primary tumour are irradiated, generally after chemotherapy, and the C.N.S. receives prophylactic radiotherapy. Curative radiotherapy is indicated in cases of non-operable small cell carcinoma. Irradiation with doses of 60-70 Gy produced 5-years-survival rates of 10-14% in cases classified as T 1 -T 2 N 0 M 0 . (orig.) [de

    Urethral carcinoma in 2 females has been treated with irradiation together with adjunct chemotherapy. In case 1, a 73-year-old female with squamous cell carcinoma was successfully treated with irradiation of 4,000 rad and peplomycin of 60 mg intravenously given. She has been free from the disease for the past 43 months. In case 2, a 61-year-old female with transitional cell carcinoma was initially treated with irradiation of 5,000 rad together with peplomycin 90 mg, which was followed by another 5,000 rad irradiation. The tumor recurred and the patient was operated on for cystourethrectomy and partial resection of the vagina. A further chemotherapy of cisplatin, peplomycin, and mitomycin C was instituted. She died of the tumor recurrence 23 months after the first visit to our clinic. Diagnosis and treatment modalities on the female urethral carcinoma are briefly discussed. (author)

    2011-01-01

    The frequency of hepatocellular carcinoma (HCC) is increasing in the western world and the role of radiotherapy is more and more discussed. Classically, hepatocellular carcinoma was considered as a radioresistant tumour: in fact, modern radio-biologic studies, performed on cell lines directly established from patients, showed that hepatocellular carcinoma has the same radiosensitivity than the other epithelial tumours. From clinical studies, its α/β ratio has been estimated to be around 15 Gy. Radiosensitivity of normal hepatic parenchyma is now well evaluated and some accurate NTCP models are available to guide hepatic irradiation. The biology of hepatocellular carcinoma is also better described: the combination of radiotherapy and targeted therapies will be a promising approach in the near future. (authors)

    We report a case of carcinoma of the esophagus in a 58 years old woman with achalasia, who has been diagnosed since 30 years ago, which initiated by surgical treatment (myotomy) and the symptoms recurred since 3 years ago. According to the progress of the disease, Malignancy was strongly suspected due to prolonged stasis and mucosal irritation caused by achalasia (achalasia carcinoma sequence). Because of these contributing factors for the development of serious complications such as Malignan...

    Pulmonary sarcomatoid carcinomas are a rare group of tumors accounting for about one percent of non-small cell lung carcinoma (NSCLC). In 2015, the World Health Organization classification united under this name all the carcinomas with sarcomatous-like component with spindle cell or giant cell appearance, or associated with a sarcomatous component sometimes heterologous. There are five subtypes: pleomorphic carcinoma, spindle cell carcinoma, giant cell carcinoma, carcinosarcoma and pulmonary blastoma. Clinical characteristics are not specific from the other subtypes of NSCLC. Epithelial to mesenchymal transition pathway may play a key role. Patients, usually tobacco smokers, are frequently symptomatic. Tumors are voluminous more often peripherical than central, with strong fixation on FDG TEP CT. Distant metastases are frequent with atypical visceral locations. These tumors have poorer prognosis than the other NSCLC subtypes because of great aggressivity, and frequent chemoresistance. Here we present pathological description and a review of literature with molecular features in order to better describe these tumors and perhaps introduce new therapeutics. Copyright © 2016.

    Fragments of the nafenopin-induced pancreatic acinar cell carcinoma of rat have been examined in vitro for patterns of intracellular protein transport and carbamylcholine-induced protein discharge. Continuous incubation of the fragments with [3H]-leucine for 60 minutes resulted in labeling of rough endoplasmic reticulum, Golgi cisternae, and mature zymogen granules, revealed by electron microscope autoradiography. This result indicates transport of newly synthesized protein from the rough endoplasmic reticulum to mature zymogen granules in approximately 60 minutes. The secretagogue carbamylcholine induced the discharge of radioactive protein by carcinoma fragments pulse-chase labeled with [3H]-leucine. A maximal effective carbamylcholine concentration of 10(-5) M was determined. The acinar carcinoma resembles normal exocrine pancreas in the observed rate of intracellular protein transport and effective secretagogue concentration. However, the acinar carcinoma fragments demonstrated an apparent low rate of carbamylcholine-induced radioactive protein discharge as compared with normal pancreatic lobules or acinar cells. It is suggested that the apparent low rate of radioactive protein discharge reflects functional immaturity of the acinar carcinoma. Possible relationships of functional differentiation to the heterogeneous cytodifferentiation of the pancreatic acinar carcinoma are discussed

    Full Text Available Abstract Background Ocular sebaceous carcinoma can masquerade as benign lesions resulting in delay of diagnosis. Early recognition is even more difficult in young patients where the disease rarely occurs. Here, we provide a clinicopathological correlation of ocular sebaceous carcinoma in a young individual lacking history of hereditary cancer or immunosuppression. Findings A detailed histopathological study including p53 DNA sequencing was performed on an aggressive sebaceous carcinoma presenting in a healthy 32 year-old Caucasian woman. She had no history of retinoblastoma, evidence for a hereditary cancer syndrome, or radiation therapy. However, she potentially was at risk for excessive UV light exposure. A detailed review of the literature is also provided. A moderately well differentiated sebaceous carcinoma was established histopathologically arising from the meibomian gland of the upper eyelid. In most areas, the cytoplasm contained small but distinct Oil-red-O positive vacuoles. Direct sequencing of p53 identified a G:C→A:T mutation at a dipyrimidine site. The mutation results in substitution of arginine for the highly conserved glycine at residue 199 located at the p53 dimer-dimer interface. Energy minimization structural modeling predicts that G199R will neutralize negative charges contributed by nearby inter- and intramonomeric glutamate residues. Discussion This study points to the importance of recognizing that sebaceous carcinoma can occur in young patients with no evidence for hereditary cancer risk or radiation therapy. The G199R substitution is anticipated to alter the stability of the p53 tetrameric complex. The role of UV light in the etiology of sebaceous carcinoma deserves further study. Our findings, taken together with those of others, suggest that different environmental factors could lead to the development of sebaceous carcinoma in different patients.

    At the Proton Medical Research Centre, University of Tsukuba, a pilot study of proton-beam radiotherapy was performed in 12 patients with the following types of carcinoma: Bowen's disease (4), oral verrucous carcinoma (5), and squamous cell carcinoma (3). They received total doses of 51-99.2 Gy in fractions of 2-12.5 Gy. All tumours responded well to the treatment. All four lesions of Bowen's disease, three of the five oral verrucous carcinomas, and the three squamous cell carcinomas completely regressed following irradiation. Two squamous cell carcinomas recurred during the follow-up period. One recurrent squamous cell carcinoma was successfully treated by a salvage surgical operation, and in the other case the patient refused further therapy. In two verrucous carcinomas there was 90% regression of tumour volume. No severe radiation-related complication occurred. (Author)

    Full Text Available Primary Fallopian Tube Carcinoma (PFTC is rare and accounts for about 0.3% of all gynecologic cancers. Less than 1500 cases have been reported in the literature. It arises in postmenopausal women and typically presents with abdominal pelvic pain, vaginal bleeding and watery discharge. However, a correct diagnosis is rarely achieved preoperative, and in many cases, the diagnosis is made after incidental surgery for unrelated conditions commonly being ovarian carcinoma . Compared with ovarian carcinoma, PFTC more often presents at early stages, but it has a worse prognosis. PFTC is usually managed in the same manner as ovarian cancer. We report a case of Left PFTC that presented as Left ovarian mass, and we briefly review the literature.

    Full Text Available Adrenal sarcomatoid carcinomas are extremely rare tumors presenting with extensive locoregional spread at the time of diagnosis. Patients succumb to metastases within a couple of months. As a result, very few cases are reported in the literature until now. We present a case of a 62-year old female with non-functional sarcomatoid carcinoma of the right adrenal gland. There was no radiological evidence of locoregional metastases. Patient underwent right adrenalectomy. Follow up after 3 months showed para-aortic lymphadenopathy and similar left adrenal mass on computed tomography. Patient refused further treatment and succumbed to the disease. A brief case report with review of literature is presented.

  13. Thyroid carcinoma in children

    Akhzari, F.

    2002-01-01

    Thyroid cancer is rare in children, with only 3-6% of thyroid malignancies occurring in children, and constitutes but 6% of head and neck tumors. Over 95% thyroid cancer are differentiated, and 10% of these occur in children of adolescents. Any of the histologic types that occur in adults may be in children, but they are most often differentiated thyroid carcinomas. The etiologies of thyroid carcinoma are unknown, but factors considered in pathogenesis include irradiation, sex and age. The incandesce of thyroid carcinoma in a solitary coddle in a child has been described as high as 70%. History and /or physical examination alone are unlikely to advance the diagnosis, and with exception of plasma CT in medullary thyroid carcinoma, blood studies are unhelpful in the diagnosis of thyroid carcinoma. Radiographs and ultrasound imaging are helpful in planning treatment and follow-up, but are unlikely to be needed for initial diagnosis. One of the main indication of thyroid scan in the pediatric group is thyroid nodule. FNAB is established as the most effective method of diagnosis in adults, although in children it may be less reliable. While radionuclide scintigraphy may be considered for initial screening, FNAB is well established and its specificity allows it to negate the need for a substantial number of operation. Treatment of differentiated thyroid carcinoma in children is more controversial. Some authors maintain that modified or subtotal thyroidectomy is appropriation this disease, others maintain that total thyroidectomy is required Nevertheless, radioiodine therapy is considered to be standard in the treatment of iodine-avid thyroid carcinomas for ablation of the thyroid remnant following surgery and for treatment of iodine-avid distant diseases. The front-line treatment of medullary thyroid carcinoma is aggressive surgery. Total thyroidectomy is indicated, In general treatment with chemotherapy, extemal radiation and I-131 are not helpful, however radioactive

    Urachal carcinoma is a rare neoplasm, which accounts for only 0.5–2% of bladder malignancies, and arises from a remnant of the fetal genitourinary tract. A 46-year-old woman presented with a history of pelvic pain and frequent daytime urination. Ultrasound (US), computed tomography (CT), and magnetic resonance (MR) demonstrated a supravesical heterogeneous mass with calcifications. The patient underwent a partial cystectomy with en-bloc resection of the mass and histopathological examination revealed the diagnosis of urachal adenocarcinoma. Urachal carcinomas are usually associated with poor prognosis and early diagnosis is fundamental. CT and MR are useful to correctly diagnose and preoperatively staging

    Skin carcinoma is the most frequent of all cancers. The main risk factor is represented by solar exposition and, so, individuals with special risk are xeroderma pigmento sum (enzymatic defect of DNA repair), light phototype person, sun-seekers, outdoor-workers and patients treated with high doses of PUVA. X-rays, mineral oils, tar and arsenic are also known skin carcinogens. HPV can also participate to skin carcinogenis alone or associated with UV particularly in immunosupressed sujets. Subjects with predisposition for skin carcinoma can be pointed out and cautioned. Detection of preepitheliomatous lesions is easy; actinic keratosis are the main signs.

    Full Text Available Oral squamous cell carcinoma (OSCC is the most common epithelial malignancy affecting the oral cavity. The most common sites for the development are lateral surface of tongue and floor of mouth; the least common sites are soft palate, gingiva, and buccal mucosa. Gingival squamous cell carcinoma can mimic a multitude of oral lesions and enlargements, especially those of inflammatory origin. In addition, predisposing and presenting factors are different from those of other OSCCs. Careful examination as well as routine biopsy are crucial for accurate diagnosis.

    Full Text Available O carcinoma mucoepidermóide é uma neoplasia infreqüente da árvore traqueobrônquica e de etiologia ainda indeterminada. Sua localização endobrônquica preferencial freqüentemente causa sintomas respiratórios obstrutivos e pneumopatias de resolução lenta. Normalmente, são tumores de crescimento lento, mas que podem apresentar comportamento agressivo, com invasão local e metástases para linfonodos, dependendo das suas características histopatológicas. O tratamento de eleição é o cirúrgico, com ressecção completa, seja através de lobectomia ou broncotomia e broncoplastia. O prognóstico dependerá do grau de diferenciação celular desses tumores. Relata-se um caso dessa rara neoplasia descrevendo suas características clínicas, radiológicas e o tratamento cirúrgico.Mucoepidermoid carcinoma is an uncommon neoplasm of the tracheobronchial tree, of unknown etiology. Its preferred endobronchial location often results in respiratory symptoms such as obstruction of the airways and lung diseases of slow recovery. They usually are slow growing tumors although they may present an aggressive behavior with local invasion and lymph node metastases depending on their histopathologic characteristics. The mainstay therapy is complete surgical resection either by means of lobectomy or by lung sparing procedures such as bronchotomy and bronchoplasty. Prognosis depends upon the degree of cellular differentiation of the tumors. The authors report a case of this rare neoplasia and describe the clinical and radiographic characteristics, and the surgical treatment.

  4. Gut-associated Lymphoid Tissue (GALT) Carcinoma or Dome Carcinoma?

    Science.gov (United States)

    Rubio, Carlos A; Schmidt, Peter T

    2016-10-01

    The vast majority of colorectal carcinomas (CRCs) evolve from mucosa not associated to lymphoid tissues aggregates via the adenoma-carcinoma sequence or via the serrated pathway. Rarely CRCs evolve from gut mucosa associated to lymphoid tissue (GALT). Based on the presence of a circumscribed elevation in the colorectal mucosa, GALT carcinomas are also referred to as dome carcinomas (DC). Descriptions of the surface mucosa covering 21 GALT-CRCs appearing in pathological reports were reviewed. Three of the 21 GALT-CRCs fulfilled the criteria of dome carcinoma. Of the remaining 18 GALT-CRCs, nine were described as polypoid lesions, five as plaque-like lesions, two as sessile elevated lesions or mass, one as ulcerated and one as histological finding. Hence, only 14.3% (n=3) of the 21 GALT-CRCs displayed a dome configuration, whereas the majority, 85.7% (n=18), exhibited structures other than dome shapes at gross or at histologic examination. It becomes apparent that by using "dome" in addressing carcinomas in the colorectal mucosa, many cases of GALT carcinomas might be overlooked. Another drawback of using the "dome" nomenclature is that dome-like outlines may be detected in small metastatic tumors in the submucosa or in small colorectal carcinomas not arising from GALT mucosa. Instead, by using "GALT carcinoma", that is the histologic diagnosis in addressing these neoplasias, all cases of GALT-CRCs will be included.

    Recently, magnetic resonance imaging (MRI) and transrectal or transvaginal ultrasound (TRUS, TVUS) had an important place in imaging techniques of cervical carcinomas and raise the question of modifying the imaging strategies. For the diagnosis of primitive tumor, those techniques cannot take the place of clinical examination and gross examination. In the assessment of parametrial involvement, TRUS which has better accuracy than clinical examination, and MRI which is considered as the most accurate technique, have an important role to play. In the follow-up and the detection of recurrences, MRI is actually considered as the best imaging technique. The authors, according to recent data in literature and their own experience, present basic concepts of imaging strategies for staging and follow-up of cervical carcinomas [fr

    1982-06-01

    CT was investigated in 125 cases of hepatocelluar carcinoma and 47 cases of metastatic hepatic neoplasm. The entire contour of each tumor was traced and the average CT value in the tumor was estimated. As a result, the CT value for hepatocellular carcinoma tended to be higher on plain CT and also after contrast enhancement. The CT findings seen frequently were as follows: capsule in 76 cases (60.8%) and septum in 67 cases (53.6%); tumor thrombus in portal vein in 39 cases (31.2%) and that in inferior vena cava in 3 cases (2.4%); localized enlargement of hepatic bile duct in 24 cases (19.2%). These findings were rarely seen in the cases of metastatic hepatic neoplasm. As a relatively outstanding feature of hepatic metastases, a double contour, like concentric circles or contour lines, with a relatively large inner circle or contour line, was found in 21 cases (44.7%). By paying attention to the change of CT value on contrast enhancement and the characteristic image of each case, hepatocellular carcinoma could be differentiated from metastatic hepatic neoplasm with high probability.

    From 1971 through 1982, 442 patients with laryngeal carcinoma were seen at the Leiden University Hospital. They were treated either with radiotherapy alone, sandwich therapy (pre- and postoperative radiotherapy) or by surgery followed by postoperative irradiation. Three hundred and sixty-six patients with glottic or supraglottic tumours could be analysed with respect to two different treatments, complications of treatment and some prognostic factors. Two endpoints of analysis were used: disease-free interval and survival to cfancer death. In patients with glottic or supraglottic carcinoma, the survival of patients with advanced disease, treated with radiotherapy only, was worse as compared to the survival of the same category of patients who were treated with sandwich therapy (p<0.005). In small supraglottic tumours, the survival with both therapy policies was equal. There was no influence on prognosis of histological differentiation of the tumour. It appeared that interruption of radiotherapy for more tah two days had an adverse effect on survival in patients with glottic carcinoma (p=0.0001). (author). 16 refs.; 4 figs.;

    We performed dynamic CT in 30 cases of hepatocellular carcinoma, and concluded as below. Detecting the stain in the early phase of the dynamic series, it is possible to make a diagnosis of hepatocellular carcinoma. The dynamic CT is effective in a case of small hepatocellular carcinoma in which it is difficult to gain an accurate diagnosis in the routine CT study. The dynamic CT is also effective in the differential diagnosis of hepatic lesions, as other hepatic lesions such as hemangioma and metastatic liver cancer show different patterns compared with hepatocellular carcinoma.

    Thyroid carcinoma is the most commonly diagnosed endocrine malignancy. Its incidence is currently rising worldwide. The discovery of genetic mutations associated with the development of thyroid cancer, such as BRAF and RET, has lead to the development of new drugs which target the pathways which they influence. Despite recent advances, the prognosis of anaplastic thyroid carcinoma is still unfavourable. In this review we look at emerging novel therapies for the treatment of well-differentiated and medullary thyroid carcinoma, and advances and future directions in the management of anaplastic thyroid carcinoma.

    Thyroid gland carcinomas usually appear as afunctional and hypofunctional lesions on thyroid scintigrams, but some rare cases of thyroid carcinoma with scintigraphic hyperfunctional lesions have also been reported. The aim of our retrospective study was to elucidate the frequency of carcinomas in patients operated for solitary hyperfunctional thyroid nodules and to represent their demographic and clinical features. During one decade (1997/2006), 308 patients were operated for solitary hyperfunctional thyroid nodules in the Centre for Endocrine Surgery in Belgrade. Malignancy was revealed in 9 cases (about 3 %) by histopathological examination. In 6 cases papillary microcarcinomas were found adjacent to dominant hyperfunctional adenomas, while in 3 cases (about 1 %) real hyperfunctional carcinomas were confirmed. Follicular carcinoma was diagnosed in 2 cases and papillary carcinoma in one. All 3 patients were preoperatively hyperthyroid. In both patients with follicular carcinoma we performed lobectomies. In the third case we carried out a total thyroidectomy considering the intraoperative frozen section finding of a papillary carcinoma. According to our results the frequency of solitary hyperfunctioning thyroid carcinomas is about 1 %, so that the possibility that a hyperfunctional nodule is malignant should be considered in the treatment of such lesions. © Georg Thieme Verlag KG Stuttgart ˙ New York.

    Both small cell carcinoma and sarcomatoid carcinoma of the urinary bladder are highly aggressive tumors, and a concurrence of these tumors is extremely rare. We report a case of urinary bladder cancer with small cell carcinoma as a predominant component, accompanied by sarcomatoid carcinoma and conventional urothelial carcinoma (UC). Although the small cell carcinoma component had resolved on receiving chemoradiotherapy, rapid growth of the residual tumor led to a fatal outcome. A 47-year-old man presented with occasional bladder irritation and had a 2-year history of asymptomatic hematuria. Cystoscopy revealed a huge mass in the urinary bladder, and transurethral resection was performed. Microscopically, small cell carcinoma was detected as the major tumor component. Spindle-shaped sarcomatoid cells were also observed that were intermingled with small cell carcinoma and conventional UC. In addition, a sheet-like growth of the lipoblast-like neoplastic cells was observed focally. Initially, by providing chemoradiotherapy, we achieved a marked tumor regression; however, the tumor rapidly regrew after the completion of chemoradiotherapy, and the patient underwent radical cystectomy. Only conventional UC and sarcomatoid carcinoma were identified in the cystectomy specimen. The patient died of the disease 4 months after cystectomy. Urinary bladder cancer may include a combination of multiple aggressive histologies as in the present case. Because the variation in the tumor components may affect the efficacy of therapy, a correct diagnosis of every tumor component is necessary. Copyright © 2016 Elsevier GmbH. All rights reserved.

    With the advent of gray scale ultrasonographic equipment, the parenchymal disease of liver is more easily evaluated. Ultrasonography is a non-invasive technique, different from angiography, and performed without discomfort to patient. And also ultrasonography can be used in assessing the liver in cases showing equivocal scintigraphy and in differentiation of solid and cystic masses, first detected on scintigrams. Therefore, the complementary use of ultrasonography, Tc-99m-sulfur colloid scan and angiography provides better diagnostic accuracy for the detection of hepatocellular carcinoma, and moreover, sequential ultrasonographic studies in the same patient are valuable of following the course of hepatocellular carcinoma and monitoring the effectiveness of therapy for hepatocellular carcinoma. In thirty patients with histologically proven hepatocellular carcinoma, an analysis of ultrasound manifestation is made and the results are as follows; 1. Ultrasound manifestation of hepatocellular carcinoma by gray scale showed four different sonographic patterns including discrete echo free, discrete echogenic, ill defined echogenic and mixed patterns. 2. The size of hepatocellular carcinoma by ultrasonographic measurement was larger than 5 cm in diameter in 28 cases. 3. In 7 cases performed with angiography, all echogenicities of hepatocellualr carcinoma were correlated with the findings of vascularity of angiography. 4. In cases combined with liver cirrhosis, the sonographic pattern of hepatocellular carcinoma appeared to be discrete or ill defined echogenic patterns.

    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 1 , 16T 2 , 32T 3 and 22 T 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 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

    A 16-year-old girl presented to our unit with crampy abdominal pain, change in bowel habit, a subjective impression of weight loss and a single episode of haematochezia. She was found to have a rectosigmoid adenocarcinoma and proceeded to laparoscopic anterior resection, whereupon peritoneal metastases were discovered. She received chemotherapy and is alive and well ten month later with no radiological evidence of disease. Colorectal carcinoma is rare in the paediatric population but is increasing in incidence. Early diagnosis is critical to enable optimal outcomes.

    Full Text Available Cancer has become a first order health problem worldwide, despite the great diagnostic and therapeutic programs achieved during the last years. This is a clinical case of an 81- year-old patient with personal and social history of promiscuous and unprotected sexual behavior that shows a vegetative lesion in his gland and numerous inguinal adenopathies. Biopsy confirms the diagnosis of squamous cell carcinoma infiltrating the penis, which is a relatively rare pathology which is generally diagnosed belatedly. Partial amputation of the penis was considered to be performed, but there was no consent on behalf of his family. The patient’s general condition was getting worse until he died.

    Purpose: To discuss a variety of technical and clinical issues concerning the management of carcinoma of the uterine cervix. Radiation therapy plays a central role in the management of patients with invasive carcinoma of the uterine cervix. Although survival rates are high for patients with small volume disease, clinicians continue to search for approaches that might improve treatment results for patients who have bulky central disease, evidence of regional dissemination or other factors associated with a high rate of disease recurrence. New technical approaches have contributed to controversy about the best means of optimizing therapeutic ratio. This course will review current approaches to the management of cervical cancer. Technical aspects of intracavitary and external beam treatment will be emphasized. Problems with brachytherapy dose specification will be discussed as will technical factors that may influence the incidence of treatment-related complications. Current understanding of the natural history of disease and of clinical factors that influence the rate of disease recurrence will be reviewed, including the importance of tumor volume, lymph node involvement, and histologic type on natural history and prognosis. The possible role of controversial methods of clinical evaluation such as lymphangiography and surgical staging will be discussed. Some of the more controversial aspects of treatment including the indications of radiation therapy vs. surgical therapy for stage IB disease, the role of extended field therapy, postoperative therapy, adjuvant hysterectomy, and neoadjuvant or concurrent chemotherapy will be discussed. Conclusions from the recent NCI consensus conference on cervical cancer will be reviewed

    Hepatocellular carcinoma (HCC) is currently the sixth most common type of cancer with a high mortality rate and an increasing incidence worldwide. Its etiology is usually linked to environmental, dietary or life-style factors. HCC most commonly arises in a cirrhotic liver but interestingly an increasing proportion of HCCs develop in the non-fibrotic or minimal fibrotic liver and a shift in the underlying etiology can be observed. Although this process is yet to be completely understood, this changing scenario also has impact on the material seen by pathologists, presenting them with new diagnostic dilemmas. Histopathologic criteria for diagnosing classical, progressed HCC are well established and known, but with an increase in detection of small and early HCCs due to routine screening programs, the diagnosis of these small lesions in core needle biopsies poses a difficult challenge. These lesions can be far more difficult to distinguish from one another than progressed HCC, which is usually a clear cut hematoxylin and eosin diagnosis. Furthermore lesions thought to derive from progenitor cells have recently been reclassified in the WHO. This review summarizes recent developments and tries to put new HCC biomarkers in context with the WHOs reclassification. Furthermore it also addresses the group of tumors known as combined hepatocellular-cholangiocellular carcinomas.

    Carcinomas in children are rare and have not been well studied. We conducted a population-based case-control study and examined associations between birth characteristics and childhood carcinomas diagnosed from 28 days to 14 years during 1980-2004 using pooled data from five states (NY, WA, MN, TX, and CA) that linked their birth and cancer registries. The pooled data set contained 57,966 controls and 475 carcinoma cases, including 159 thyroid and 126 malignant melanoma cases. We used unconditional logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (CIs). White compared with 'other' race was positively associated with melanoma (OR=3.22, 95% CI 1.33-8.33). Older maternal age increased the risk for melanoma (OR(per 5-year age increase)=1.20, 95% CI 1.00-1.44), whereas paternal age increased the risk for any carcinoma (OR=1.10(per 5-year age increase), 95% CI 1.01-1.20) and thyroid carcinoma (OR(per 5-year age increase)=1.16, 95% CI 1.01-1.33). Gestational age birth weight, and birth order were not significantly associated with childhood carcinomas. This exploratory study indicates that some birth characteristics including older parental age and low gestational age may be related to childhood carcinoma aetiology.

    Primary carcinoma of the duodenum represents about 0.35% of all gastrointestinal carcinomas and is thus a rare disease. The radiological diagnosis of a duodenal origin is made more difficult by the close proximity of the pancreas, biliary system, right kidney and transverse colon. Histologically, duodenal malignant tumours are usually adenocarcinomas. Between 1973 and 1983, eight patients with primary duodenal carcinomas were diagnosed at the University of Tuebingen. Average age of the patients was 67 years. There was no sex difference. Average survival was 3.3 years. (orig.) [de

    Cutaneous squamous cell carcinoma (cSCC) is a malignant neoplasm of the skin characterized by an aberrant proliferation of keratinocytes. Cutaneous SCC is the second most common malignancy globally, and usually arises in the chronically sun-damaged skin of elderly white individuals. From a pathologist's perspective, it is important to differentiate cSCC from the benign and reactive squamoproliferative lesions and identify the high-risk features associated with aggressive tumor behavior. In this article, we provide an up-to-date overview of cSCC along with its precursor lesions and important histologic variants, with a particular emphasis on the histopathologic features and molecular pathogenesis.

    Nasapharyngeal carcinoma is a rare disease. Oftenly, the diagnostic is made for advanced disease. Localized tumors, T1 or T2 NO observed a good prognosis and are locally controlled in more than 90 % of the cases by radiotherapy alone. The standard treatment of locally advanced disease is combined chemoradiation. A special vigilance of fast decrease of the volume of the pathological lymph nodes, sometimes associated to loss of weight might indicate an adaptive dosimetric revision. The treatment of recurrent disease is of great importance. Surgical indications are limited but should be discussed in multidisciplinary tumor board when possible. Surgical nodal sampling has to be proposed for nodal recurrence as well as reirradiation, which could be indicated according to the technical issues. Copyright © 2016. Published by Elsevier SAS.

    For inoperable bronchial carcinomas the prognostication is unfavourable still in this era of combined radiological and chemical therapy. Yet the situation is better than it was two years ago. Important international therapeutical investigations have substantially enriched our knowledge. This concerns first of all parvicellular anaplastic carcinomas of the bronchi where, thanks to the combination chemotherapy-radiotherapy-chemotherapy, new possibilities have turned up and the radiotherapy of the primary tumor, the mediastinum and the neurocranium has become firmly established in spite of initial scepticism. As regards non-parvicellular carcinomas, the development is still behind. Post-operative radiotherapy occupies a place in the non-curative resection of bronchial carcinomas. As to the rest, the radiotherapist encounters only palliative indications at the moment excepting controlled clinical studies. It is to be hoped that new combination therapies including hyperthermal measures, radiosensitizer, bleomycin and other chemotherapeuticals will open up now paths. Supraregional therapeutical investigations should be initialled in this sector.

    Review of the literature and report of a new case of laryngeal cancer after irradiation of a benign lesion of the neck. These cases obviously become rare since benign lesions are no longer irradiated. Today the risk of inducing a second carcinoma by a successful irradiation of the first tumor becomes more important. A study of 109 patients, irradiated for laryngeal carcinoma and surviving with no evidence of disease for a period of at least 5 years has been performed. 8 of these patients developed a second primary in the previously irradiated area after 7-15 years. These second carcinomas are not rare if one considers that most patients with laryngeal carcinoma are 60-70 years old and therefore the life expectance on an average is low. These facts should be taken into consideration when deciding between surgical or radiation therapy in younger patients with high life expectance. (orig.) [de

    1983-01-01

    Cholangiograms and clinical histories of 82 patients with biopsy-proved bile duct carcinoma were reviewed. The carcinomas were classified according to morphologic findings and clinical outcome. Ulcerative colitis and antecedent inflammatory disease of the biliary tree, particularly primary sclerosing cholangitis, seem to predispose to the development of bile duct carcinoma. Focal stenotic lesions were the most common morphologic type (62/82). Polypoid carcinomas and diffuse sclerosing carcinomas were less common and of about equal frequency. Prognosis was best for patients with polypoid carcinomas and worst for those with diffuse sclerosing carcinomas. In 69 cases (84%), the tumors involved the intrahepatic or proximal extrahepatic ducts, makin curative resection difficult or impossible. Patients with carcinomas limited to the more distal extrahepatic bile ducts had a longer average survival and a higher probability of surgical cure. Proper management of patients with bile duct carcinoma requires a complete and accurate cholangiographic evaluation of the morphology, location, and extent of the disease

    Hepatocellular carcinomas can be further divided into distinct subtypes that provide important clinical information and biological insights. These subtypes are distinct from growth patterns and are on based on morphologic and molecular findings. There are 12 reasonably well-defined subtypes as well as 6 provisional subtypes, together making up 35% of all hepatocellular carcinomas. These subtypes are discussed, with an emphasis on their definitions and the key morphologic findings. Copyright © 2017 Elsevier Inc. All rights reserved.

  5. Radiosensitivity of carcinoma of esophagus

    1986-01-01

    With a detailed graphic reconstruction of radiation effects shown in 11 operation materials of carcinoma of esophagus with preoperative irradiation, histologic analysis of the radiosensitivity was made. Residual cancer lesions in 11 operation specimens contained adenocarcinoma elements. Carcinoma of esophagus belonged to mixed carcinoma (syn. metaplastic cancer). Radioresistant nature resulted from the remnant adenocarcinoma elements. Protruded type (3 cases) showed about 60 % of residual cancer after preoperative irradiation of 40 Gy (Lineac or 60 Co.). The residual cancer nests histologically revealed well-differentiated squamous cell carcinoma with a few signet-ring cells, compatible with mucoepidermoid carcinoma. In protruded type, the mixed carcinoma was composed of segmental, disproportioned zonal squamous metaplasia. As its histogenetic origin, a main duct of esophageal gland was suggested. In 9 autopsy cases of esophageal cancer, recurrent lesion within the field of irradiation failed to respond to radiotherapy. In recurrent residual lesions, a higher proportion of adenocarcinoma elements was noticed. Therefore, the cancer part formed by a high rate of metaplasia was markedly responsive to irradiation, whereas increased residue of adenocarcinoma elements was enhanced the radioresistant property. In a middle thoracic esophagus (Im) corresponding to the commonest site of esophageal cancer, the distribution of esohageal glands was in a high density with a constant ratio of density in each age group particularly in male. In age groups with higher incidence of carcinoma of esophagus, esophageal glands markedly increased especially in male, in contrast with the indefinite number and density ratio in female cases. A high density of esophageal glands was noticed in the upper (Iu) and lower (Im) parts of the 2nd physiologic constriction, in proportion to the commonest site of carcinoma of esophagus. (J.P.N.)

    Imaging of uterine cervix carcinoma has evolved during the last decade. Recent developments in magnetic resonance imaging have expanded the role of MRI in evaluating the pathology of uterine cervix carcinoma. MRI is now the modality of choice for tumor staging, evaluating tumor response to treatment, diagnosing recurrences and for evaluating pregnant patients. MRI images will soon be used to calculate dosimetry for brachytherapy with matching and fusion software. (author)

    Renal oncocytoma, although rare, is being diagnosed more frequently, and criteria to differentiate it from other tumors have been described. Multiple oncocytomas have been reported, but an association between multiple oncocytomas and renal carcinoma in the same kidney has not been described. The authors report a case with two oncocytomas and a renal carcinoma in the right kidney as well as a right adrenal adenoma

In the United States, HCC is the ninth leading cause of cancer deaths. Despite advances in prevention techniques, screening, and new technologies in both diagnosis and treatment, incidence and mortality continue to rise. Cirrhosis remains the most important risk factor for the development of HCC regardless of etiology. Hepatitis B and C are independent risk factors for the development of cirrhosis. Alcohol consumption remains an important additional risk factor in the United States as alcohol abuse is five times higher than hepatitis C. Diagnosis is confirmed without pathologic confirmation. Screening includes both radiologic tests, such as ultrasound, computerized tomography, and magnetic resonance imaging, and serological markers such as α-fetoprotein at 6-month intervals. Multiple treatment modalities exist; however, only orthotopic liver transplantation (OLT or surgical resection is curative. OLT is available for patients who meet or are downstaged into the Milan or University of San Francisco criteria. Additional treatment modalities include transarterial chemoembolization, radiofrequency ablation, microwave ablation, percutaneous ethanol injection, cryoablation, radiation therapy, systemic chemotherapy, and molecularly targeted therapies. Selection of a treatment modality is based on tumor size, location, extrahepatic spread, and underlying liver function. HCC is an

    Twenty-two patients with Stage I through IV primary vaginal squamous cell carcinomas treated for cure with radiation therapy are reviewed, with particular emphasis on the relationship of dose to complications and local control. All but 2 patients received 4000 to 6000 rad whole pelvis irradiation plus at least one radium application. Local control was 91%, with an absolute 2-year disease-free survival of 82%. The degree of anaplasia was found to influence prognosis, with all local and distant failures resulting from high-grade lesions. The complication rate was modest, with no fistulae or serious bowel complications. An analysis of total dose (external plus radium) with respect to local failure and complications showed that no major complications occurred at a combined dose below 9000 rad. An analysis of the individual contributions of external irradiation and radium implants showed that all but one very minor complication occurred at a radium dose of 4000 rad or higher. From these data, overall treatment planning and total dose recommendations are made

    Hyperthyroidism due to thyroid carcinoma is rare, and most cases are caused by hyperfunctioning metastatic thyroid carcinoma rather than primary carcinoma. Among primary hyperfunctioning thyroid carcinoma, multifocal thyroid carcinoma is exceedingly rare, with the only one case being reported in the literature. Here, we describe the case of a 62-year-old woman with multifocal functioning thyroid carcinoma. Technetium-99m (99m Tc) scintigraphic imaging showed four hot areas in the thyroid gland. Histopathological examination of all four nodules revealed papillary carcinoma, corresponding to hot areas in the 99m Tc scintigram. DNA sequencing of the thyrotropin receptor (TSH-R) gene from all nodules revealed no mutation, indicating that activation of TSH-R was unlikely in the pathophysiogenesis of hyperfunctioning thyroid carcinoma in the present case.

    Purpose: To study the CT appearances of thyroid carcinoma and its cervical metastatic lymphadenopathy, as well as to evaluate the diagnostic criteria of tumor invasion of adjacent structures. Methods: CT findings of surgery and pathology proved thyroid carcinoma in 52 patients were analyzed. Results: All of the primary tumor were heterogeneous in density, 32 tumors (82.5%) were ill-defined. Fine granular calcifications were revealed in 11 primary tumors and metastatic lymph nodes in 5 cases. Cystic formation with intracystic high density papillary-like nodules were found in 4 primary tumors and metastatic lymphadenopathy in 5 cases. Trachea, esophagus and carotic artery invasion were proved by surgery in 22, 21 and 10 cases respectively. Serrated inner wall and tumor nodule protrusion into tracheal lumen were the definite signs of trachea invasion. Use tumor encasement over 1/2 of the circumference of esophagus and 1/3 of the circumference of carotid artery as the diagnostic criterion of invasion, sensitivity was 71.4%, 100.0% specificity was 96.3%, 95.2% respectively. Conclusion: Fine granular calcification and cystic formation with high attenuation intracystic papillary-like nodules were characteristic manifestations of primary thyroid carcinoma (especially papillary carcinoma) and its metastatic lymphadenopathy as well. Contrast enhanced CT scan is helpful in the diagnosis of thyroid carcinoma and the delineation of tumor extent, which is very important in surgical planning

    Esophageal carcinoma has a special place in gastrointestinal carcinomas because it contains two main types, namely, squamous cell carcinoma and adenocarcinoma. Carcinoma esophagus patients require some form of palliation because of locally advanced stage or distant metastasis, where it cannot be subjected to curable treatment with surgery and chemoradiation. Many modalities of palliation of dysphagia are available, but the procedure with least morbidity, mortality, and long-term palliation of...

    Merkel cell carcinoma is a rare aggressive neuroendocrine carcinoma of the skin predominantly affecting elderly Caucasians. It has a high rate of local recurrence and regional lymph node metastases. It is associated with a poor prognosis. Complete spontaneous regression of Merkel cell carcinoma has been reported but is a poorly understood phenomenon. Here we present a case of complete spontaneous regression of metastatic Merkel cell carcinoma demonstrating a markedly different pattern of events from those previously published.

    Nasophryngeal carcinoma is an unusual neoplasm among squamous cell carcinomas of the head and neck. The tumor is rare in most parts of the world but is strikingly common in several Asian subpopulations, notably Chinese in Hong Kong and Guangdong Province. The Epstein-Barr virus is intimately related to the disease and elicits the formation of antibodies that are useful for diagnosis and follow-up study. The virus has not been conclusively shown to cause nasopharyngeal cancer, however. Histologically, nasopharyngeal carcinoma is anaplastic in 75% of cases and better differentiated in 25% of patients. All tumors are treated by high-dose radiation to the primary site and both sides of the neck. Surgical treatment, in the neck only, is reserved for irradiation failures. The prognosis is better in patients younger than 40 years, in patients without clinical cervical nodal involvement and, unexpectedly, in patients with anaplastic tumors. 18 references, 2 figures, 2 tables

    Neuroendocrine lung carcinomas may be classified as Kulchitzky cell carcinoma (KCC) I (classic carcinoids), II (atypical carcinoids), and III (small cell carcinomas). The authors reviewed the clinical, CT, and pathologic findings in 31 patients with KCC. KCC I occurred mainly in younger nonsmoking women, and on CT were small (1.8 cm average diameter) and showed lymphadenopathy in one of ten patients. KCC II were found mainly in older smoking men and were larger (3.9 cm, P < .001), and four of ten patients had lymphadenopathy. KCC III occurred in older smoking men and were large (4.2 cm), and 11 of 11 patients had lymphadenopathy. Sputum cytology and percutaneous and bronchoscopic biopsy were often nondiagnostic or misleading. The authors conclude that chest CT provides additional discriminating information in the preoperative diagnosis of KCC

    Patients with a rising serum carcinoembryonic antigen level and no clinical or roentgenographic evidence of recurrent or metastatic cancer present a treatment dilemma. Eleven such patients, 10 with a previously treated colorectal carcinoma and 1 with a previously treated breast carcinoma, received an injection of the anticarcinoembryonic antigen monoclonal antibody ZCE-025 labeled with the radioisotope indium 111. Nuclear scintigraphy was performed on days 3 and 5 through 7 to detect potential sites of tumor recurrence. The monoclonal antibody scan accurately predicted the presence or absence of occult malignancy in 7 (64%) patients. Second-look laparotomy confirmed the monoclonal antibody scan results in the patients with colorectal cancer, and magnetic resonance imaging confirmed metastatic breast cancer. This study demonstrates that In-ZCE-025 can localize occult carcinoma and may assist the surgeon in facilitating the operative exploration. In-ZCE-025 assisted in the initiation of adjuvant therapy for the patient with breast cancer

    Ríos, Antonio; Rodríguez, José M; Parrilla, Pascual

    2015-12-01

    Differentiated thyroid carcinoma includes 2 different tumor types, papillary (PC) and follicular carcinoma (FC), and although similar, their prognosis is different. FC is uncommon, and this has led to it often being analyzed together with PC, and therefore the true reality of this tumor is difficult to know. As a result, the diagnostic and therapeutic management and the prognostic factors in differentiated carcinoma are more predictive of PC than FC. In this review we analyze the current state of many of the therapeutic aspects of this pathology. The best surgical technique and the usefulness of associated lymphadenectomy is also analyzed. Regarding post-surgical ablation with 131I, the indications, doses and usefulness are discussed. For the remaining therapies we analyze the few indications for radiotherapy and chemotherapy, and of new drugs such as tyrosine kinase inhibitors. Copyright © 2015 AEC.

    Parathyroid carcinoma is a rare disease of unknown etiology. This study presents a case of parathyroid carcinoma in a patient with tertiary hyperparathyroidism. Despite a successful kidney transplantation, the intact parathyroid hormone (iPTH) level of the patient was elevated consistently and could not be controlled by medical therapy. Due to the development of tertiary hyperparathyroidism with bone pain and osteoporosis, subtotal parathyroidectomy was performed 4 months after the kidney transplantation. Histological evaluation revealed that one of four parathyroid lesions was a parathyroid carcinoma, while the others were diffuse hyperplasia. Postoperative laboratory studies indicated a decreased level of iPTH. A positron emission tomography-computed tomography performed 6 months after the operation revealed no evidence of local recurrence or distant metastasis. Copyright © 2013.

    1987-01-01

    Ovarian carcinoma presents a difficult management problem. Localized disease is difficult to diagnose and advanced disease is usually present by the time the patient presents with symptoms (pain, discomfort, distention, mass, and so on). Surgery alone is inadequate because even if a complete resection is performed approximately 50% of cases recur. Postoperative adjuvant therapy is given in the form of radiation therapy, radioisotopes, or chemotherapy for stage I, stage II, and optimal stage III disease. No clear benefit can be ascribed to any treatment. It is evident, however, that abdominopelvic irradiation is superior to pelvic irradiation alone; many of patients receiving pelvic irradiation alone fail in the upper abdomen owing to occult disease. Prognosis depends on many variables in addition to stage: grade of tumor, histology, age of patient,and completeness of surgery. Several studies have tried to incorporate these variables into their results. Dembo perhaps has been the most diligent in incorporating them into appropriate low-, intermediate- and high-risk groups. Patients with residual macroscopic or bulk disease have the poorest prognosis; chemotherapy is the usual first-line treatment choice, although no optimal treatment is known. Regimens usually include cisplatin; many single agent and multiagent drugs have been tried. The challenge of the future lies in earlier diagnosis; those diagnosed early can attain long term survival. The problem lies in choosing the appropriate therapy because randomized controlled studies are few and all modalities can be effective. No clear picture emerges about the best treatment, although there is a slight indication that irradiation affords better intra-abdominal control. Continued studies are needed to prove this

  8. Radioembolization of hepatocellular carcinoma.

    2010-12-01

    In this review paper, available data on radioembolization of unresectable hepatocellular carcinoma (HCC) using commercially available radiopharmaceuticals, respectively (131)I-Lipiodol, Therasphere (glass-microspheres) and SIRspheres (resin-microspheres) are reviewed. In the palliative setting, (131)I-Lipiodol was shown to yield response rates of 17-92% which in patients with portal vein thrombosis (PVT) translate into a survival benefit as evidenced by a phase III randomized trial. Furthermore, in terms of efficacy, (131)I-Lipiodol is as efficacious as trans-arterial chemoembolization (TACE) but far better tolerated. In the adjuvant setting, improved recurrence-free and overall survival when compared to surgery alone have been reported but these results warrant confirmation by randomized prospective trials. Similar to (131)I-Lipiodol, when administered in a palliative setting, radioembolization using (90)Y microspheres was proven effective for selected cases of non-resectable HCC and well tolerated. Available data suggest that Therasphere treatment outperforms TACE both in terms of response as in terms of event-free survival in unresectable HCC. However, this finding needs confirmation by randomized prospective trials. Therasphere treatment was also shown to limit progression of HCC allowing potential candidates for orthotopic liver transplantation (OLT) more time to wait for donor organs as well as to downstage the HCC disease to such an extent that patients that were initially not, as yet become eligible for OLT with a gain in survival. Finally, Therasphere was shown to be safe and efficacious in HCC patients presenting with PVT, reason for which approval was granted for this indication by the FDA.

We report a case of primary squamous cell carcinoma of the orbital soft tissues. Surgical resection offered the best treatment for the patient. Complete resection of the lesion was achieved. The patient received adjuvant radiotherapy due to the proximity of the lesion to the surgical margins. Surgical treatment is feasible and should be considered as part of the surgeon's arsenal. However, therapeutic decisions must be made on a case-by-case basis

    Between 1971 and 1976, 33 patients with adenocarcinoma of the prostate T2-T4 and without evidence of distant metastases have been treated with high energy radiotherapy 50-70Gy given to the primary tumour. 72% showed local response to the treatment. Actuarial 5 years survival (uncorrected) for patients primarily treated with radiotherapy was 52%, but for patients who had earlier received oestrogens, only 16%. The results in terms of local control as well as survival were best for category T2 and T3 patients who had not previously received hormone treatment. The response rate was better for moderately differentiated carcinomas than for poorly differentiated carcinomas.

    Full Text Available Metastasis of prostate carcinoma to the testis is seldom reported. The tumour may spread from the prostatic urethra by retrograde venous extension, arterial embolism or through direct invasion into the lymphatics and lumen of the vas deferens. Clinical manifestations of secondary testicular tumours from the prostate are most often unsuspected clinically and are instead detected incidentally during orchidectomy. Less frequently, a palpable mass is detected, which may be confused with a primary testicular neoplasm. We report a case of a 66-year-old patient with adenocarcinoma of the prostate, and a left testicular tumour that was diagnosed as metastases from prostate carcinoma after radical orchidectomy.

    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.

    Objective:To investigate the significance of telomerase activity in breast carcinoma with its respect to axillary lymph node status. Methods: Telomerase activity was analyzed in 88 breast carcinomas and 16benign breast lesions, using polymerase chain reaction (PCR)-based telomeric repeat amplification protocol (TRAP) assay. Results: Telomerase activity was detected in 75 (85%) of 88 breast carcinomas (including three breast carcinomas in situ which were all positive for telomerase activity), whereas in benign breast lesions analyzed only 2(12.5%) of 16 cases were positive for telomerase activity. The difference between the two groups was statistically significant (P<0.001). Besides,telomerase activity was expressed significantly higher in node-positive breast carcinoma (93%) than in nodenegative ones (77%) (P<0.05). Conclusion: Our results suggest that telomerase activation plays an important role during breast carcinoma development. It is possible that this enzyme may serve as an early indication of breast carcinoma.

    Since February, 1977, 735 patients having a history of receiving radiation therapy for benign conditions of the head and neck areas during infancy and childhood were examined in a thyroid screening program, and 159 patients were found to have palpable thyroid nodules. These patients had thyroid function tests and indirect laryngoscopy and were followed closely on suppression therapy consisting of either Cytomel or thyroid extract. Thyroidectomy was advised in those in whom the nodules persisted or increased in size. This study documents the incidence of carcinoma and other benign pathological changes and postoperative complications in this group of patients. So far, 49 patients had either a lobectomy with isthmusectomy or a total thyroidectomy. Eleven patients were found to have carcinoma (six had papillary, fou had mixed papillary and follicular, and one had follicular carcinoma). Three patients had a therapeutic modified neck dissection following the documentaion of microscopic involvement of paratracheal lymph nodes. A high incidence of chronic nonspecific thyroiditis, postradiation fibrosis, and follicular adenomas were also found in these patients. Three patients had temporary hypocalcemia (two weeks) and none had wound infection, hematoma, or postoperative nerve palsy. Of patients who had surgical resection, 22.4% showed thyroid carcinoma

    Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

    Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous neoplasm that has exhibited an exponential increase in incidence in the past 3 decades. Combined MCC and cutaneous squamous cell carcinoma (SCC/MCC) is an uncommon variant of MCC that exhibits worse prognosis than pure MCC. To describe the clinical presentation, dermoscopy, and histology of an unusual subtype of combined SCC/MCC. A 73-year-old white woman presented with an ulcerated and violaceous 10-mm plaque on her right jawline that had been present for 2 to 3 months. On dermoscopy, the lesion was predominantly milky pink to red with peripheral crusting and large-caliber polymorphous vessels. Histology revealed SCC in situ above and adjacent to MCC. The tumor was excised with clear margins, and sentinel lymph node scintography was negative for nodal involvement. © The Author(s) 2016.

    Background Mucoepidermoid carcinoma (MEC) of the lung is a rare subtype of non-small cell lung cancer. There is no consensus regarding optimal management for this disease. Case report We present a case of MEC of the lung in a 75 year-old female with a history of superficial urothelial carcinoma of the bladder. The patient was found to have an asymptomatic lung mass. Initial biopsy suggested metastatic recurrence of urothelial carcinoma and therefore, cisplatin and gemcitabine chemotherapy was administered prior to surgical resection. Pathological analysis of the resected specimen confirmed a diagnosis of stage IIIA MEC with focal high-grade features including transitional cell-like areas. Adjuvant radiotherapy was administered due to a positive microscopic resection margin. No chemotherapy was given due to lack of supporting data. The patient developed widespread metastatic disease 3 months following completion of radiotherapy and died 1 month later. Conclusion This case demonstrates the possibility of dual pathology in cases where metastatic disease is suspected. The use of small tissue samples may complicate diagnosis due to the heterogeneity of malignant tumours. PMID:24936321

    2014-11-01

    Recent years have brought an enhanced understanding of Merkel cell carcinoma (MCC) biology, especially with regard to the Merkel cell polyoma virus as a causative agent. Differences between Merkel cell polyomavirus-positive and Merkel cell polyomavirus-negative MCC in morphology; gene expression, miRNA profiles and prognosis have been reported. Origin of MCC is controversial. Presence of neurosecretory granules has suggested that these carcinomas originate from one of the neurocrest derivatives, most probably Merkel cells; the name Merkel cell carcinoma is now widely accepted. Expression of PGP 9.5, chromogranin A and several neuropeptides, initially regarded as specific markers for neural and neuroendocrine cells, has recently been shown in a subset of lymphomas. MCC commonly expresses terminal deoxynucleotidyl transferase and PAX5. Their co-expression under physiologic circumstances is restricted to pro/pre-B cells and pre-B cells. These findings lead to the hypothesis by zur Hausen et al. that MCC originates from early B cells. This review was intended to critically appraise zur Hausen's hypothesis and discuss the possibility that MCC is a heterogenous entity with distinct subtypes. © 2014 John Wiley & Sons A/S.

    Abstract The differences between invasive lobular and ductal carcinomas affect the diagnostic and therapeutic management for patients with breast cancer. In most cases, this can be accomplished because of distinct histomorphologic features. However, occasionally, this task may become quite difficult, in particular when dealing with the variants of infiltrating lobular carcinoma. Lobular carcinoma has been considered a variant of mucin-secreting carcinoma with only intracytoplasmic mucin. The ...

    1999-01-01

    The incidence of thyroid carcinoma increases significantly following exposure to ionizing irradiation. However, the mechanisms of radiation-induced tumorigenesis at the molecular and chromosomal levels have not been identified. In order to gain some indication of the processes affecting the thyroid epithelium, cytogenetic and molecular genetic investigations were performed on childhood thyroid carcinomas that developed after the Chernobyl nuclear accident in Belarussia, and on secondary thyroid tumours that developed after radiotherapy. At the cytogenetic level, the radiation-induced tumours were shown to have an increased frequency of translocations, multiple and complex chromosome aberrations, and novel breakpoints for structural chromosome aberrations. At the molecular level, different alterations of the RET protooncogene were detected in 65% of the Belarussian tumours. (orig.) [de

    Full Text Available A formidable threat to the health of women, cervical carcinoma can be prevented in many cases with adequate screening. The current guidelines for cervical carcinoma screening were created as joint recommendations of the American Cancer Society (ACS, the American Society for Colposcopy and Cervical Pathology (ASCCP and the American Society for Clinical Pathology (ASCP in 2012, and later accepted and promoted by the American Congress of Obstetricians and Gynecologists (ACOG. The 2012 recommendations underscore the utility of molecular testing as an adjunct to cytology screening for certain women and provide guidance to clinicians based on different risk-benefit considerations for different ages. This manuscript will review screening techniques and current recommendations for cervical cancer screening and human papilloma virus (HPV testing, as well as possible future screening strategies.

    1986-01-01

    Twenty-eight patients with pancreatic carcinoma, 23 (82 %) of whom had Stage III or IV, received intraoperative radiotherapy (IOR) with curative or non-curative surgery. Electron beams (10 to 18 MeV) with doses of 20 to 40 Gy were delivered to the tumor. Eight of 26 patients with unresectable tumor had postoperative external irradiation of 10.5 to 50 Gy. Abdominal and back pain relief was achieved after IOR in 12 (71 %) and in 6 (60 %) of the 26 patients, respectively. Appetite was promoted in 11 patients. In the case of unresectable carcinoma, survival time tended to prolong in the 8 patients receiving both IOR and postoperative external irradiation. One patient developed perforation of the colon probably caused by IOR. (Namekawa, K.)

    This retrospective study reports on the occurrence of multiple carcinomas among the patients of our Department of Radiotherapy. Examination of 1290 patients during 1978 to 1980 showed in 76 cases (5.8%) simultaneously or successively secondary or tertiary tumours. These multiple tumours were most frequent in the mammary gland, in the female genital organs and in the respiratory system. Women had an incidence which was double of that displayed by men. Diagnosis and therapy of malignant tumours must always consider the possibility of multiplicity of carcinomas, either simultaneously or succesively, appearing spontaneously or as a result of iatrogenic influences. This applies in particular to the multicentric and bilateral occurrence of the early types of cancer of the female breast. (orig.) [de

    Normally, differentiated thyroid carcinoma(DTC) is a disease of good prognosis, but about 30% of the tumors are dedifferentiate, which are inaccessible to standard therapeutic procedures such as 'operation, 131 I therapy and thyroid hormone'. Both internal and abroad experts are researching a new therapy of dedifferentiated thyroid carcinoma--gene therapy. Many of them utilize methods of it, but follow different strategies: (1) transduction of the thyroid sodium/iodide transporter gene to make tissues that do not accumulate iodide treatable by 131 I therapy; (2) strengthening of the anti-tumor immune response; (3) suicide gene therapy; (4) depression the generation of tumor cells; (5) gene therapy of anti- vascularization.

    To evaluate the role of palliative surgical treatment in patients with advanced pancreatic carcinoma. Study Design: Case series. Place and Duration of Study: Surgical Ward of Khyber Teaching Hospital, Peshawar, from January 2005 to January 2009. Methodology: The study included patients with pancreatic carcinoma admitted with advanced, unresectable carcinoma of the pancreas. Patients with resectable tumours and with previous history of gastric or biliary surgery were excluded. Palliative procedures were performed after assessment of the tumour and its confirmation as unresectable on ultrasound and CT scan + ERCP. Postoperatively all patients were referred to oncologist. Complications and mortality were noted. Results: There were 40 patients, including 24 males and 16 females with mean age 58.72 +- 6.42 years. The most common procedure performed was triple bypass in 21 (52.50%) patients followed by choledocho-, cholecysto-, hepaticoand gastro-jejunostomy in various combinations. Wound infection occurred in 7 patients and was more common in patients with co-morbidities. Biliary leakage occurred in 03 patients. Postoperative cholangitis occurred in 3 patients while 7 patients had minor leak from the drain site. Four patients developed UTI, while 5 patients had signs of delayed gastric emptying. Two patients had upper gastrointestinal bleeding. Three patients died due to septicemia and multiple organs failure. Rest of the patients were discharged in stable state. The mean hospital stay was 8.40 +- 3.48 days and median survival was 7.72 +- 2.39 months. Conclusion: Surgical palliation for the advanced carcinoma pancreas can improve the quality of life of patients and is associated with minimum morbidity and mortality. (author)

    Full Text Available 755 cases of gastric carcinoma were studied that had been treated at the Hospital San Juan de Dios, of Bogotá, from 1953 to 1960. At the time of consultation the disease was in an advance stage; it appears that incidence is high if a comparison is made with other published studies, and the disease is on the increase; its higher occurrence in men is confirmed, predominating in men between the ages of 40 to 60 years. Attention is called to the four principal symptoms: pain, anorexia, vomiting and loss of weight; and the high operative mortality' is emphasized. 1. It is necessary to insist on campaings that will make feasible the earlier diagnosis of gastric carcinoma. 2. Patients should be more carefully evaluated surgically. 3. Intestinal parasitism should not be a definitive diagnosis in our midst, when a patient complains of epigastric pain, or anorexia, or vomiting, or loss of weight. 4. No relationship was found between the blood group distribution and gastric carcinoma. 5. The social welfare service should establish a better follow up (control over the patients operated on.

    Full Text Available Background. Microcystic variant of urothelial carcinoma is one of the new variants of urothelial carcinoma that was added to the WHO classification in 2004. Aims. To review the literature on microcystic variant of urothelial carcinoma. Methods. Various internet search engines were used to identify reported cases of the tumour. Results. Microscopic features of the tumour include: (i Conspicuous intracellular and intercellular lumina/microcysts encompassed by malignant urothelial or squamous cells. (ii The lumina are usually empty; may contain granular eosinophilic debris, mucin, or necrotic cells. (iii The cysts may be variable in size; round, or oval, up to 2 mm; lined by urothelium which are either flattened cells or low columnar cells however, they do not contain colonic epithelium or goblet cells; are infiltrative; invade the muscularis propria; mimic cystitis cystica and cystitis glandularis; occasionally exhibit neuroendocrine differentiation. (iv Elongated and irregular branching spaces are usually seen. About 17 cases of the tumour have been reported with only 2 patients who have survived. The tumour tends to be of high-grade and high-stage. There is no consensus opinion on the best option of treatment of the tumour. Conclusions. It would prove difficult at the moment to be dogmatic regarding its prognosis but it is a highly aggressive tumour. New cases of the tumour should be reported in order to document its biological behaviour.

    Full Text Available Penile carcinoma frequency varies widely in different parts of the world and comprises 1–10% of all the malignancies in males. Majority of the cases of penile carcinoma are squamous cell carcinoma of penis comprising 60% to 70% of all cases. Warty carcinoma of penis is an unusual neoplasm and a variant of penile squamous cell carcinoma comprising 5%–10% of all the variants. The other histological variants include basaloid, verrucous, papillary, sarcomatous, mixed, and adenosquamous carcinoma. The various histological entities with an exophytic papillary lesions including warty carcinoma are together referred to as the “verruciform” group of neoplasms. The warty carcinoma has to be differentiated from these lesions and is typically distinguished by histological features of hyperkeratosis, arborescent papillomatosis, acanthosis, and prominent koilocytosis with nuclear pleomorphism. We present a case of 65-year-old male with growth measuring 6×4 cm in the penis who underwent total penectomy and was diagnosed as warty carcinoma penis.

    Circumscribe breast cancer is a well demarcated mass with or without a lobulated border simulating a benign tumor like fibroadenoma on mammography or breast US and is reported as approximate 10% of the incidence among primary breast carcinoma(1.2). Pathologically medullary, colloid, papillary, intraductal and rarely invasive ductal carcinomas are included in this group which show the less intense desmoplastic reaction than the scirrhous type cancer, resulting in the most favorable prognosis of all carcinoma of the breast. Among 214 primary breast carcinoma during the past 8 years, we experienced 6 case of pathologically proven circumscribed breast cancer(2 cases of medullary carcinoma, 1 of colloid carcinoma, 1 of intracystic papillary carcinoma, 2 of comedo type intraductal carcinoma). Clinically 2 cases showed bloody nipple discharge from one hole of a unilateral nipple orifice. Mammography showed a well circumscribed nodule with or without partial lobular contour and no pathologic calcification. Breast sonographic findings were a well defined heterogeneous hypoechoic nodule with weak posterior acoustic enhancement. Characteristically a thin dilated lactiferous duct between the mass and the nipple on US could be detected in 2 cases which clinically was accompanied by bloody nipple discharge. Although the mammographic criteria is promising as benign tumor, the possibility of circumscribed as benign tumor, the possibility of circumscribed breast carcinoma must be considered in heterogeneous hypoechoic nodule with weak posterior acoustic enhancement in US, especially in the presence of a dilated lactiferous duct between the mass and the nipple with bloody nipple discharge.

The duration of symptoms varies from 6 months to 2 years. Among the various aetiological factors, smoking, alcohol intake, spicy hot food intake, industrial pollution and achalasia cardia are a few worth mentioning. AIM OF THE STUDY To evaluate the differences in the predisposing factors causing squamous cell carcinoma and adenocarcinoma of oesophagus in this part of India. MATERIALS AND METHODS The study is conducted in the Department of Surgery at Government Medical College Hospital, Kozhikode; Kerala. One hundred patients attending the Department with history of Dysphagia were included after thorough history taking, clinical and endoscopic examination and found to have malignant growths in the oesophagus which was confirmed by biopsy and histopathological examination. Various aetiological factors were elicited and analysed in both the histological varieties of malignancy of oesophagus. OBSERVATIONS AND RESULTS Significant number of patients with history of paan chewing presented with histological picture of squamous cell carcinoma as compared to patients who had adenocarcinoma. Gastroesophageal reflux disease was more commonly associated with adenocarcinoma. Out of 37 patients with adenocarcinoma, 31 patients had history of gastroesophageal reflux disease (83.8%. 6 patients had no history of gastroesophageal reflux disease (16.2% within histology. Consumption of hot drinks, tea and coffee more than 10 per day has been analysed. 52 were consuming, 48 were not consuming, P value 0.179 non-significant. CONCLUSIONS Squamous cell carcinoma is more prevalent as compared to adenocarcinoma in present study. The main factor that has emerged is lifestyle, dietary habit, smoking and alcohol, and environmental factor. Consumption of alcohol and smoking is known risk factors in

    To evaluate the diagnostic utility of Hep par-1 in differentiating hepatocellular carcinoma from metastatic carcinoma taking histopathology as a gold standard. Study Design: Comparative cross-sectional study. Place and Duration of Study: Pathology Department, Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, from April 2007 to February 2008. Methodology: Hep par-1 immunohistochemical stain was performed on 60 cases of liver carcinoma, 30 cases each of metastatic and hepatocellular carcinoma. Information regarding patient age, gender, sign and symptoms, radiographic findings, histological grade of tumour, and expression of Hep par-1 on hepatocellular and metastatic carcinoma were recorded on proforma sheet. Sensitivity, specificity, positive and negative predictive values, and accuracy of Hep par-1 were calculated using the formulas. Results: Hep par-1 expression was noted in 25 out of 30 cases of hepatocellular carcinoma (83%). Out of 30 cases of metastatic carcinoma, only one case expressed staining in < 5% tumour cells and remaining 29 cases showed no reactivity. The age of the patients with hepatocellular carcinoma ranged from 40 to 76 years with a median age of 60.5 years and 40 - 75 years for metastatic carcinomas with a median age of 57.5 years. Conclusion: Hep par-1 is a reliable immunohistochemical marker for cases of hepatocellular carcinoma (HCC). It can be used along with other markers in morphologically difficult cases when differential diagnosis lies between poorly differentiated HCC and metastatic carcinoma of liver. (author)

    Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (HaCaT) and squamous cell carcinoma (A431) and also investigate the expression of heparanase in basal cell carcinoma, squamous cell carcinoma and eyelid skin of individuals not affected by the disease (control). Glycosaminoglycans were quantified by electrophoresis and indirect ELISA method. The heparanase expression was analyzed by quantitative RT-PCR (qRTPCR). The A431 strain showed significant increase in the sulfated glycosaminoglycans, increased heparanase expression and decreased hyaluronic acid, comparing to the HaCaT lineage. The mRNA expression of heparanase was significantly higher in Basal cell carcinoma and squamous cell carcinoma compared with control skin samples. It was also observed increased heparanase expression in squamous cell carcinoma compared to the Basal cell carcinoma. The glycosaminoglycans profile, as well as heparanase expression are different between HaCaT and A431 cell lines. The increased expression of heparanase in Basal cell carcinoma and squamous cell carcinoma suggests that this enzyme could be a marker for the diagnosis of such types of non-melanoma cancers, and may be useful as a target molecule for future alternative treatment.

  12. Invasive lobular carcinoma with extracellular mucin as a distinct variant of lobular carcinoma: a case report

    Full Text Available Abstract The differences between invasive lobular and ductal carcinomas affect the diagnostic and therapeutic management for patients with breast cancer. In most cases, this can be accomplished because of distinct histomorphologic features. However, occasionally, this task may become quite difficult, in particular when dealing with the variants of infiltrating lobular carcinoma. Lobular carcinoma has been considered a variant of mucin-secreting carcinoma with only intracytoplasmic mucin. The presence of extracellular mucin is a feature of ductal carcinoma. Herein is presented a case of lobular carcinoma with extracellular and intracellular mucin in a 43-year-old female patient, and confirmed by immunohistochemistry. Up to the present, infiltrating lobular carcinoma displaying extracellular mucin has not been described in the literature except two case.

    Forty-one cases with nasopharyngeal carcinoma (NPC) treated in our department between 1991 and 2007 were clinically analyzed. The mean age of the cases was 53 years old, and the male-to female ratio was 3.6:1. The most common chief complaint was ear symptoms followed by neck, eye, and nose symptoms. The most common histology was squamous cell carcinoma, followed by undifferentiated carcinoma, adenocarcinoma, and spindle cell carcinoma. More than half of the cases were classified as clinical stage IV. For squamous cell carcinoma, undifferentiated carcinoma, spindle cell carcinoma cases, concurrent chemoradiotherapy followed by adjuvant chemotherapy was applied. For adenocarcinoma cases, transpalatal resection and postoperative radiotherapy was applied. The five-year overall survival rate was 64.1% and the disease-specific five-year survival rate was 71.2%. No significant statistical differences were seen between early stage (I, II) and late stage (III, IV), between I, II, III stage and IV stage. Recurrence occurred in 24.4% of the cases, and distant metastasis was more dominant than local recurrence. For the diagnosis and treatment of NPC, proper detection of NPC from variegated symptoms, and chemoradiotherapy for squamous cell carcinoma cases were considered to be important. (author)

    Forty-four patients of nasopharyngeal carcinoma, treated in Tsukuba University Hospital between March 1988 and March 1998, were reviewed in order to assess the adequacy of our treatment protocol. Most of the cases except 5 were histologically diagnosed as squamous cell carcinoma including 25 of lymphoepithelioma (poorly-differentiated squamous cell carcinoma). Thirty-two out of 39 squamous cell carcinoma cases have fallen into Stage IV category (UICC, 1987) , and all of the non-squamous cell carcinoma cases were also categorized as Stage IV. The basic protocol for nasopharyngeal squamous cell carcinoma was the combination of full-dose irradiation and chemotherapy using cisplatin/carboplatin and peplomycin. The metastatic cervical lymphnodes in 9 cases, too massive to control by this treatment, were surgically dissected after the treatment. Recurrence was noted in 9 cases who were rehospitalized and salvaged medically and/or surgically. As a consequence, the overall 5-year survival rate was 71.4% for squamous cell carcinoma. On the other hand, only one of the 5 non-squamous cell carcinoma cases died of the disease. (author)

    A case of ductal carcinoma of the parotid gland is described. The medical literature contains only 13 previous reports on this kind of adenocarcinoma of the parotid gland. The tumour is characterized by its histologic resemblance to ductal carcinomas of the breast and prostate. The course of previously described cases suggests that this tumour has a highly aggressive biological behaviour.

    Between 1969 and 1985, 30 patients with carcinomas of the eyelid were treated by radiation, including 19 primary cases and 11 secondary cases. The latter were less controlable than the former. According to histology, there were 21 squamous cell carcinomas, 6 basal cell carcinomas and 3 adenocarcinomas. Among the 21 patients with squamous cell carcinomas, 5 had local recurrences, 10 had lymph node metastasis and 3 had distant metastasis. Patients with other histological classifications had no local recurrences, except for one who received incomplete therapy due to diabetes. Almost all of the controlled patients with squamous cell carcinomas were treated with a TDF value greater than 90. Although the visual function was damaged by irradiation in seven patients, the lesions of 6 of them were too advanced to avoid radiation injuries. (author)

  2. Unusual manifestations of secondary urothelial carcinoma

    Full Text Available High-grade papillary urothelial carcinoma regularly invades the bladder wall, adjacent prostate, seminal vesicles, ureters, vagina, rectum, retroperitoneum, and regional lymph nodes. In advanced stages, it may disseminate to the liver, lungs, and bone marrow. On rare occasions, unusual metastatic foci like skin have been reported. The incidence of urothelial carcinoma has increased with associated rise in variants of urothelial carcinoma and unusual metastatic foci. It is imperative that urologists and pathologists are aware of the unusual variants and unusual metastatic locations to expedite the diagnostic process. Hereby we report an unusual case of secondary involvement of spinal nerve by conventional urothelial carcinoma. Also a second case of rhabdoid variant of urothelial carcinoma showing synchronous involvement of bladder and subcutaneous tissue of upper extremity is presented.

    Xeroderma pigmentosum is a rare autosomal-recessive disorder that appears in early childhood. Squamous cell carcinoma is not uncommon in patients with xeroderma pigmentosum and mostly involving the face, head, neck, and scalp. However, squamous cell carcinoma of the scalp may exhibit an aggressive course. Here, we present a huge squamous cell carcinoma of the scalp in a three-years-old child with xeroderma pigmentosum. In addition, we illustrate the challenges of a child with xeroderma pigmentosum who grows up in a sunny environment where the possibility of early onset of squamous cell carcinoma is extremely high in any suspected skin lesion. In xeroderma pigmentosum patients, squamous cell carcinoma of the scalp can present early and tends to be unusually aggressive. In sunny areas, proper education to the patient and their parents about ultra-violet light protection and early recognition of any suspicious lesion could be life-saving.

    Full Text Available OBJECTIVE: To investigate the vessel endothelial growth factor (VEGF as a risk factor in squamous cell carcinoma of the penis (SCCP. METHODS: Forty-seven patients with penile carcinoma were evaluated retrospectively. The mean age and standard deviation were 61.1±11.7 years. All of them were treated by penectomy and those with positive nodes underwent groin lymphadenectomy. Tumor grading was 35 G1 and 12 G2/3. Primary lesion stage was 24 pT1 and 23 pT2-4. Positive inguinal nodes were observed in 15 patients. Selected paraffin embedded sections were submitted to VEGF immunohistochemical analysis by the avidin-biotin-immunoperoxidase method with antigen retrieval. All slides were examined using an automatic analyzer system and the proportion of labeled cells in 10 high magnification power fields (400X were recorded in a blind analysis. RESULTS: Median (% labeling index was 2.3 in G1 versus 2.2 in G2/3 tumors (p=0.60, and 4.0 in pT1 versus 1.8 pT2-4 tumors (p=0.10. The respective data for pN0 patients was 2.8 and for pN+ was 2.1 (p=0.20. Survival curves showed no association with patients survival. CONCLUSION: In squamous cell carcinoma of the penis the VEGF immunoexpression has no association with tumor grade or stage, as well as with patient survival.

    The purpose of this study is to evaluate mammographic findings of invasive ductal carcinoma (IDC) and invasive lobular carcinoma(ILC) and to find differential points between the two. 239 patients, who underwent mammography prior to surgery and were proved to have IDC(patients) or ILC(15 patients) pathologically, were analized retrospectively. On mammogram, presence of mass and microcalcification were analized. When there was a mass on mammogram, lesion opacity was classified into high, equal, or low opacity and border of the mass was classified into spiculated, poorly marginated, and well-marginated. When there was no definite mass, mammographic findings were classifie into asymmetric opacity and no mass. Masses were observed in 168 patients(75%) of IDC and 12 patients(80%) of ILC. Border of the masses were spiculated(n=50, 22.3%), poorly marginated(n=112, 50%), or well-marginated(n=6, 2.7%) in patients with IDC. Spiculated and poorly marginated borders were observed in 8 patients(53.3%) and 4 patients(26.7%) respectively, in patients with ILC. Microcalcifications were seen in 88 patients(17.3%) of IDC and patients(33.3%) of ILC. Although equal or low opacities were observed more frequently in ILC and microcalcifications were noted more frequently in IDC, it was difficult to differentiate the two diseases based on mammographic findings.

    2009-08-01

    Full Text Available We report a unique case of combined primary neuroendocrine carcinoma (NEC and hepatocellular carcinoma (HCC of the liver in a 65-year-old male patient. The patient underwent segmental resection of the liver and regional lymph node dissection for a tumor mass that measured 7.5 cm in diameter in the right lobe, with regional lymphadenopathy. Histologically, the hepatic tumor was composed of predominantly small-cell NEC, but admixed with a small island of moderately differentiated HCC. We speculate that the NEC originated from a poorly differentiated tumor clone of an HCC that underwent neuroendocrine differentiation, and that this tumor was now at the end stage of the transitional period from HCC to NEC, based on the small amount of disappearing HCC. Ki-67 and p53 expression were higher in the NEC than in the HCC, and the lymph nodes showed only metastatic NEC. Therefore, this kind of tumor had a more aggressive clinical course in accordance with being an NEC rather than a conventional HCC. Three months after operation, the patient had multiple recurrent tumor nodules within the liver, spreading the metastasis to the adrenal glands and para-aortic lymph nodes. The patient died 1 year after operation.

    Hepatocellular carcinoma (HCC) is the sixth most common cancer worldwide and leading cause of death among patients with cirrhosis. Treatment guidelines are based according to the Barcelona Clinic Liver Cancer staging system. The choice among therapeutic options that include liver resection, liver transplantation, locoregional, and systemic treatments must be individualized for each patient. The aim of this paper is to review the outcomes that can be achieved in the treatment of HCC with the heterogeneous therapeutic options currently available in clinical practice. PMID:25132740

    Radiofrequency ablation (RFA) is a well-established treatment modality in the treatment of early hepatocellular carcinoma (HCC) [1]. Safe trajectory of the RFA probe is crucial in decreasing collateral tissue damage and unwarranted probe transgression. As a percutaneous technique, however, the trajectory of the needle is sometimes constrained by the available imaging plane. The presence of a hemangioma beside an HCC is uncommon but poses the question of safety related to probe transgression. We hereby describe a case of transhemangioma ablation of a dome HCC.

    From 1977 through 1989, 149 patients with esophageal carcinoma were treated with external irradiation (EI) with or without high-dose rate intraluminal irradiation (HDRII) using remote afterloading system. Concerning complete response group EI alone showed higher local control rate than EI + HDRII, especially in ulcerative type. Another problem is the EI field. Fourteen of 22 patients who were salvaged by surgery due to local recurrence after EI showed marginal or out-field metastasis of the lymph node. These preliminary results suggest that HDRII is not effective for the local control of the ulcerative lesion as a boost therapy, EI should be given for the entire regional lymph nodes. (author)

    Clinical, radiological and pathological features of two cats with prostatic carcinoma are reported. In both cats the presenting history included signs of lower urinary tract disease with haematuria and dysuria. Prostatomegaly was visible radiographically in one cat; an irregular intraprostatic urethra was seen on retrograde contrast urethrography in both cats. In one of the cats, neoplasia was suspected on the basis of a transurethral catheter biopsy. Following a poor response to palliative treatment in both cases, euthanasia was performed with histological confirmation of the diagnosis

    Acinic cell carcinomas of the parotid should be considered distinct malignancies despite descriptions of low-grade malignant potential and innocuous histologic patterns. Benign-appearing tumors frequently have a clinically malignant course. Blood-borne metastases may oocur early despite gross and microscopic innocence. Indolent growth may be a characteristic of local disease, which may then be approached with less than radical parotidectomy and sacrifice of the facial nerve. These tumors prove to be radiosensitive. More agressive postoperative irradiation and palliative irradiation is recommended. Two cases of successful palliation of spinal metastases are presented as examples of radiosensitivity of this tumor

    Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous neuroendocrine malignancy. Merkel cell polyomavirus, a tumorigenic DNA virus, is present in most MCC tumors, with implications for tumor biology, diagnosis, and management. Merkel cell polyomavirus-negative tumors have a high burden of UV-signature mutations, similar to melanoma. The histopathologic diagnosis of MCC requires immunohistochemistry to exclude morphologically similar entities. Therapies for advanced disease are currently lacking. Here, the features of MCC are reviewed, including recent molecular discoveries with implications for improved therapy for advanced disease. Copyright © 2017 Elsevier Inc. All rights reserved.

    Currently, non-small cell lung carcinomas are primarily classified by light microscopy. However, recent studies have shown that poorly-differentiated tumors are more accurately classified by immunohistochemistry. In this study, we investigated the use of immunohistochemical analysis in reclassifying lung carcinomas that were originally diagnosed as squamous cell carcinoma. Tumor slides and blocks were available for histologic evaluation, and tissue microarrays were constructed from 480 patients with resected lung carcinomas originally diagnosed as squamous cell carcinoma between 1999 and 2009. Immunohistochemistry for p40, p63, thyroid transcription factor-1 (TTF-1; clone SPT24 and 8G7G3/1), Napsin A, Chromogranin A, Synaptophysin, and CD56 were performed. Staining intensity (weak, moderate, or strong) and distribution (focal or diffuse) were also recorded. Of all, 449 (93.5%) patients were confirmed as having squamous cell carcinomas; the cases were mostly diffusely positive for p40 and negative for TTF-1 (8G7G3/1). Twenty cases (4.2%) were reclassified as adenocarcinoma since they were positive for TTF-1 (8G7G3/1 or SPT24) with either no or focal p40 expression, and all of them were poorly-differentiated with squamoid morphology. In addition, 1 case was reclassified as adenosquamous carcinoma, 4 cases as large cell carcinoma, 4 cases as large cell neuroendocrine carcinoma, and 2 cases as small cell carcinoma. In poorly-differentiated non-small cell lung carcinomas, an accurate distinction between squamous cell carcinoma and adenocarcinoma cannot be reliably determined by morphology alone and requires immunohistochemical analysis, even in resected specimens. Our findings suggest that TTF-1 8G7G3/1 may be better suited as the primary antibody in differentiating adenocarcinoma from squamous cell carcinoma. PMID:25871623

    Biopsy is the technique of choice for the definitive diagnosis of endometrial carcinoma. Since lymphatic tumor spread has been demonstrated to depend on the degree of myometrial involvement, the definition of the latter with imaging techniques may significantly affect both pfognosis and therapy. We investigated, by means of MR imaging at 0.5 T, 14 patients with endometrial carcinoma, to assess both tumor stage and myometrial involvement. FIGO staging system was employed, and M parameter evaluated (M0= no myometrial involvement; M1involvement confined to the inner third; M2= Involvement confined to the middle third; M3= involvement of the whole myometrium). Another parameter was the characteristic high signal of the tumor on PD and T2W images. The patients were then operated and MR information was correlated with surgical findings. Overall diagnostic accuracy of MR imaging was 85.7% in tumor staging, and 92.2% in defining M parameter. Tumor spread into adnexa and into cervical canal was poorly demonstrated by MR imaging

    Possible deep (more than an inner third of the uterine wall) myometrial invasion and cervical extension of endometrial carcinoma were evaluated prospectively using magnetic resonance (MR) and transabdominal real-time sonography (US) in 20 and 10 patients, respectively. The data obtained from these examinations were compared with hysterosalpingography (HSG) and clinical modalities including hysteroscopy, sounding and histopathologic findings after surgery. The concordance of outlining cervical extension was between MR and hysteroscopy 85 per cent, and between US and hysteroscopy 50 per cent. Deep myometrial tumor invasion was suggested in 4/10 patients by US and in 6/20 by MR, and was confirmed in all but one in each group at histologic examination of the resected uterus. There were no false negative US or MR examinations. Transabdominal US did not prove accurate in defining local endometrial carcinoma (distinguishing between stages I and II), but it may be used as an additional tool in revealing myometrial invasion. MR, however, seems to refine the delineation of uterine tumor growth. (orig.)

    With the development of gray scale ultrasonography, detection and evaluation of hepatic parenchymal disease including space occupying lesion are easily performed and frequently used in the world. Thrity five cases of histopathologically proven and ultrasonographically suggested hepatocellular carcinoma are retrospectively studied. The results were as follows; 1. Ultrasonographic findings of hepatocellular carcinoma show hyperechoic pattern in 22 cases (63%), hypoechoic pattern in 2 cases (6%), and mixed pattern in 11 cases (31%). 2. The margin of tumor is ill-defined in 19 cases (54%) and well defined in16 cases (46%). 3. The size of tumor by sonographic measurement was large than 5 cm in diameter in 33 cases (94%). 4. The number of tumor is solitary in 19 cases and multiple in 16 cases. The sites of involved lobe were right lobe in 22 cases (63%), left lobe in 2 cases (6%), and both lobes in 11 cases (31%). 5. Associated sonographic findings were hepatomegaly with focal contour change in 25 cases (71%), splenomegaly in 16 cases (46%), cirrhosis of liver in 15 cases (43%), ascites in 11 cases (31%) and tumoral thrombosis in portal vein in 8 cases (23%). 6. The sex ratio is 6 : 1 male predominence and the age ranges from 32 to 76 years with highest incidence in 5th and 6th decades.

    External auditory canal (EAC) carcinomas are relatively rare conditions lack on established treatment strategy. We analyzed a treatment modalities and outcome in 32 cases of EAC squamous cell carcinoma treated between 1980 and 2008. Subjects-17 men and 15 women ranging from 33 to 92 years old (average: 66) were divided by Arriaga's tumor staging into 12 T1, 5 T2, 6 T3, and 9 T4. Survival was calculated by the Kaplan-Meier method. Disease-specific 5-year survival was 100% for T1, T2, 44% for T3, and 33% for T4. In contrast to 100% 5-year survival for T1+T2 cancer, the 5-year survival for T3+T4 cancer was 37% with high recurrence due to positive surgical margins. The first 22 years of the 29 years surveyed, we performed surgery mainly, and irradiation or chemotherapy was selected for early disease or cases with positive surgical margins as postoperative therapy. During the 22-years, 5-year survival with T3+T4 cancer was 20%. After we started superselective intra-arterial (IA) rapid infusion chemotherapy combined with radiotherapy in 2003, we achieved negative surgical margins for advanced disease, and 5-year survival for T3+T4 cancer rise to 80%.

    Full Text Available Human papillomavirus (HPV infection is the most common sexually transmitted disease worldwide and can result in pre-malignancies or overt malignancies of the skin and mucosal surfaces. HPV-related illnesses are an important personal and public health problem causing physical, mental, sexual and financial detriments. Moreover, this set of malignancies severely affects the immunosuppressed population, particularly HIV-positive patients and organ-transplant recipients. There is growing incidence of HPV-associated anogenital malignancies as well as a decrease in the average age of affected patients, likely related to the rising number of high-risk individuals. Squamous cell carcinoma is the most common type of HPV-related malignancy. Current treatment options for HPV infection and subsequent disease manifestations include imiquimod, retinoids, intralesional bleomycin, and cidofovir; however, primary prevention with HPV vaccination remains the most effective strategy. This review will discuss anogenital lesions in immunocompromised patients, cutaneous warts at nongenital sites, the association of HPV with skin cancer in immunocompromised patients, warts and carcinomas in organ-transplant patients, HIV-positive patients with HPV infections, and the management of cutaneous disease in the immunocompromised patient.

    The paper analyzes the case of a 73 year-old patient, masculine sex, obese, with syndrome of obstructive apnoea of the dream, reason why he uses nasal CPAP for 2 at 3 hours in the night for 2 years. It was intervened by renal carcinoma of clear cells at the end of the year 2002. The Rx of thorax preoperative had been informed as normal, but in an abdominal preoperative tomography, the presence of a mass was suggested in the base right lung thorax, reason why Tac is practiced, which demonstrates an irregular nodular image clearly, stuck to the pleura that that suggests unique metastasis of the renal carcinoma. Masses neither mediastinal adenopaties were not evidenced. In the post-operative of their nefrectomy the patient presented dehiscence of the sutures and evisceration, reason why he was re-intervened with primary closing and managed with antibiotics, achieving appropriate scaring. It was programmed for resection of the pulmonary mass. Their evolution and discusses of the case are studied

    From March of 1979 through December of 1982, 84 patients with supraglottic carcinoma were seen and evaluated in the Department of Therapeutic Radiology, Seoul National University Hospital. Of these, 68 patients were treated with a curative intent by employing either radiotherapy alone or a combined approach of radiotherapy plus surgery. Sixteen patients refused to complete the treatment program. Seventy-three per cent of patients had T3 and T4 lesions and 63% of patients had lymph node metastasis at the time of diagnosis. Actuarial recurrence-free survival at 3 year was: Stage I-III 62%, Stage III 54%, Stage IV 18%. For T1-2, T3 and T4 lesions, the actuarial recurrence free survival at 3 years were 50%, 34% and 9% respectively. Of 39 patients with treatment failure, 29 patients (78%) had uncontrol or ultimate recurrence at the primary site while 9 patients having lymph node recurrence, 14 patients(21%) had lymph node recurrence, and 5 patients had distant metastasis. It is suggested that planned combined radiotherapy is indicated for advanced but respectable supraglottic carcinoma

    Prostate cancer is the second cause of cancer death in men in the Western world. Despite progress in the treatment of advanced disease, it is recognized that the only possibility of reduction in prostate cancer death is nearly diagnosis when the disease is localized. In the present study our aim was to review the current strategy for diagnosis of prostate carcinoma. Prostate-specific antigen (PSA) is a valuable tumor marker and has demonstrated effectiveness in detecting prostate carcinoma, monitoring therapeutic efficacy, and disclosing disease recurrence. However, alternative methods are been proposed just as the free to total PSA ratio, PSA density, PSA velocity, which could improve the diagnostic sensibility and the specificity. Image diagnostic methods include transrectal ultra sound, computerized tomography, magnetic resonance image, and bone cintigraphy. The ultra sound is the best approach to guide the prostate biopsy and, together with the magnetic resonance is still useful for loco regional graduation. Computerized tomography as magnetic resonance image can be used for identification of linfonodal involvement. Bone cintigraphy is the best method for the identification of metastatic disease.

    Full Text Available Carcinoma of the ampulla of Vater is a rare gastrointestinal tumor. Additionally, cutaneous metastasis from such an internal malignancy is also uncommon. We reported the case of a 55-year-old man afflicted with ampullary carcinoma with cutaneous metastasis. The patient did not undergo the standard Whipple procedure but received chemotherapy due to apparent left neck lymph node metastasis noted by initial PET/CT imaging. The skin metastasis presented as a left neck infiltrating purpuric lesion, which was confirmed by skin biopsy approximately one year after the patient's disease was first diagnosed. Thereafter, the patient received further chemotherapy pursuant to his course of medical management. Skin metastasis usually represents a poor patient prognosis. In these cases, treatment of cutaneous metastasis typically includes systemic chemotherapy and local management such as radiation therapy or tumor excision. And when choosing a chemotherapy regimen for the ampullary cancer, the histological subtypes (intestinal or pancreatobiliary should be comprehensively considered. In our review of the literature, the intestinal type seems to have less distant lymph node metastasis, advanced local invasion, as well as recurrence than pancreatobiliary type of ampullary cancer.

    Mammography has proven to be an effective modality for the detection of early breast carcinoma. However, 4-34 percent of breast cancers may be missed at mammography. Delayed diagnosis of breast carcinoma results in an unfavourable prognosis. The objective of this study was to determine the causes and characteristics of breast carcinomas missed by mammography at our institution, with the aim of reducing the rate of missed carcinoma. We reviewed the reports of 13,191 mammograms performed over a five-year period. Breast Imaging Reporting and Data Systems (BI-RADS) were used for the mammographical assessment, and reports were cross-referenced with the histological diagnosis of breast carcinoma. Causes of missed carcinomas were classified. Of 344 patients who had breast carcinoma and had mammograms done prior to surgery, 18 (5.2 percent) failed to be diagnosed by mammography. Of these, five were caused by dense breast parenchyma obscuring the lesions, 11 were due to perception and interpretation errors, and one each from unusual lesion characteristics and poor positioning. Several factors, including dense breast parenchyma obscuring a lesion, perception error, interpretation error, unusual lesion characteristics, and poor technique or positioning, are possible causes of missed breast cancers.

    Full Text Available Pleomorphic carcinoma is a rare lesion and the literature contains few reports of pleomorphic carcinoma of the gallbladder. The present study reports a rare case of primary pleomorphic carcinoma of the gallbladder for which we were able to perform curative surgery. A 77-year-old woman with dementia developed nausea and anorexia, and computed tomography demonstrated irregular thickening of the gallbladder wall. Drip infusion cholangiography and endoscopic retrograde cholangiopancreatography revealed no stenosis of the common and intrahepatic bile ducts. We suspected carcinoma of the gallbladder without lymph node metastasis and invasion to the common bile duct. We guessed it to be resectable and performed open laparotomy. At operation, the fundus of the gallbladder was adherent to the transverse colon, but no lymph node and distant metastases were detected. Therefore, we performed curative cholecystectomy with partial colectomy. Histopathology and immunostaining showed coexistence of an adenocarcinoma, squamous cell carcinoma and sarcomatous tumor of spindle-shaped cell, as well as transition zones between these tumors. We diagnosed stage I pleomorphic carcinoma of the gallbladder. No recurrence has been observed for one and a half years. The biological behavior of pleomorphic carcinoma of the gallbladder remains unknown. It will be necessary to accumulate more case reports of this tumor in order to define diagnostic criteria.

    Prompted by the finding that the radiological incidence of small bowel ascariasis in the patient with gastric carcinoma was unexpectedly lower than the incidence in the normal population, a clinical study was performed to investigate possible relationship between gastric carcinoma and intestinal ascariasis. As a preliminary survey, we reviewed the radiological incidence of ascariasis in a total of 2,446 cases of upper GI series performed at the Department of Radiology, St Mary's Hospital Catholic Medical College. These included 1,573 normal subjects, 146 gastric carcinoma patients, 100 benign gastric ulcer and 249 duodenal ulcer patients and 378 other upper GI diseases. Following the preliminary study, a more accurate parasitologic study was conducted in another 578 normal subjects and 51 gastric carcinoma patients. The radiological incidences of ascaiasis in normal subjects and gastric carcinoma patients were 15.1% and 28.1%, respectively. The incidence of overall helminthiasis including ascaris lumbricoides, trichocephalus trichiurus and trichostrongyloides orientalis in normal subjects of the present series was 73.5%. This figure is virtually the same with 69.1% of the general population incidence reported by Kim, et al. (1971), but the incidence in gastric carcinoma patients was 94.1%. The high incidence pattern of overall helminthiasis in gastric carcinoma patients is, however, reversed as for as ascariasis is concerned. Thus, the incidence of ascariasis of gastric carcinoma patients was much lower than that of normal subjects (9.8% vs 19.4%). From the present observation, it is postulated that there can be some possible antagonistic relationship between evolution of gastric carcinoma and small bowel infestation of ascaris lumbricoides.

    Ultraviolet light (UV) is an important risk factor for cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin. These cancers most commonly affect persons with fair skin and blue eyes who sunburn rather than suntan. However, each of these cancers appears to be associated with a different pattern of UV exposure and to be mediated by different intracellular molecular pathways.Some melanocortin 1 receptor (MC1R) gene variants play a direct role in the pathogenesis of cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma apart from their role in determining a cancer-prone pigmentory phenotype (fair skin, red hair, blue eyes) through their interactions with other genes regulating immuno-inflammatory responses, DNA repair or apoptosis.In this short review we focus on the aetiological role of UV in cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin, and on some associated biopathological events.

    Full Text Available Summary: Rarely, basal cell carcinoma grows to a giant size, invading the underlying deep tissue and complicating the treatment and reconstruction modalities. A giant basal cell carcinoma on the scalp is in some cases treated with a combination of surgery and radiation therapy, resulting in local control, a satisfactory long-term cosmetic and functional result. We present a case with a neglected basal cell scalp carcinoma, treated with wide excision and postoperative radiotherapy, reconstructed with a free latissimus dorsi flap. The cosmetic result is acceptable and there is no sign of recurrence 1 year postoperatively.

    Radiotherapy is widely accepted as the first choice for nasopharyngeal carcinoma. Delayed otitis of both external and middle ears is sometimes seen as a complication after radiotherapy for head and neck cancer, especially for nasopharyngeal carcinoma. They are usually hard to manage and some produces cochlear damages, finally resulting in a sensorineural hearing loss. However, these otologic disorders are tends to be overlooked, because physicians pay less attention to them than the concerning for cancer recurrence. Therefore, studies on the otologic disorders following radiotherapy are lacking. In this study, we analyzed 24 nasopharyngeal carcinoma cases retrospectively to clarify the incidence of otologic disorders induced by radiotherapy. (author)

    Full Text Available Buccal carcinoma is one of the most common oral malignant neoplasms, especially in the South Asian region. Radiotherapy, which plays a significant role in the treatment of this carcinoma, has severe adverse effects. Different types of prosthesis may be constructed to protect healthy tissues from the adverse effects of treatment and concentrate radiation in the region of the tumor mass. However, the technique for fabrication of shielding stent with Lipowitz's alloy (cerrobend/Wood's alloy has not been well documented. This article describes detailed technique for fabrication of such a stent for unilateral buccal carcinoma patients to spare the unaffected oral cavity from potential harmful effects associated with radiotherapy.

    Metaplastic carcinoma of the breast is a rare tumor. The appearance of unexpected mesenchymal elements within the epithelial tumors is the squamous metaplasia. These tumors have a different clinical behaviour that classical breast carcinoma. We present a case of metaplastic mammary carcinoma with multiple relapses treated with a combination of chemotherapy and radiotherapy. The use of chemotherapy after local treatment has enhanced the relapse-free survival. The combined treatment modality seems to produce some benefit in the management of the local relapses of this neoplasms

    Numerous clinical, epidemiological, histological and experimental observations favour the adenoma-carcinoma sequence. Metastases occur only after invasion of the submucosa. The elevated rate of synchronous lesions (carcinomas and adenomas) is emphasized. In the rule, lymphatic spread precedes distant metastasis. Typing and grading should be performed according to the rules of WHO. The present UICC staging system will be replaced by a new 4th edition 1987. Early carcinoma (limited to the submucosa) has an excellent prognosis and may be treated by limited procedures (polypectomy, local excision) in the most cases. The modern concept of histology- and stage-adapted cancer therapy requires the pre-, intra- and postoperative cooperation with the pathologist. (Author)

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

    International Nuclear Information System (INIS)

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

    2015-01-01

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

  6. Percutaneous cryoablation for hepatocellular carcinoma

    Full Text Available Local ablation therapy is considered as a conventional treatment option for patients with early stage hepatocellular carcinoma (HCC. Although radiofrequency (RF ablation is widely used for HCC, the use of cryoablation has been increasing as newer and safer cryoablation systems have developed. The thermodynamic mechanism of freezing and thawing used in cryoablation is the Joule-Thomson effect. Cryoablation destroys tissue via direct tissue destruction and vascular-related injury. A few recent comparative studies have shown that percutaneous cryoablation for HCCs is comparable to percutaneous RF ablation in terms of long term therapeutic outcomes and complications. Cryoablation has several advantages over RF ablation such as well visualization of iceball, no causation of severe pain, and lack of severe damage to great vessels and gallbladder. It is important to know the advantages and disadvantages of cryoablation compared with RF ablation for improvement of therapeutic efficacy and safety.

    Hepatocellular carcinoma (HCC) is the fifth most common neoplasm and the third leading cause of cancer-related deaths worldwide. Cirrhosis, most often due to viral hepatitis, is the predominant risk factors for HCC and geographical differences in both risk factors and incidence are largely due to epidemiological variations in hepatitis B and C infection. Hepatic function is a relevant parameter in selecting therapy in HCC. The current clinical classification of HCC split patients into 5 stages, with a specific treatment schedule for any stage. As patients with early stages can receive curative treatments, such as surgical resection, liver transplantation or local ablation, surveillance program in high-risk populations has become mandatory. Sorafenib, a multikinase inhibitor, has recently shown survival benefits in patients at advanced stage of disease. Hopefully, new molecular targeted therapies and their combination with sorafenib or interventional and surgical procedures, should expand the therapeutic armamentarium against HCC.

    Medullary thyroid carcinoma is a biologically distinct form of thyroid cancer and accounts for 5-10% of all thyroid neoplasms. Twenty percent of MTC can occur in a familial setting either by itself or as part of the multiple endocrine neoplasm syndromes. A disciplined approach is necessary in the work-up of these patients to rule out coexistent endocrine tumors (pheochromocytomas and parathyroid). Cacitonin is a sensitive tumor marker secreted by MTC that is of prognostic value and important in the follow-up of patients. Surgery is the mainstay of treatment with a total thyroidectomy and centre compartment clearance being the minimum for patients without cervical adenopathy. Radiotherapy has a limited role and is only indicated as a palliative measure in patients with advanced/metastatic disease not amenable to surgery

    Percutaneous radiofrequency ablation (RFA) is well established in the treatment of hepatocellular carcinoma (HCC). Due to its curative potential, it is the method of choice for non resectable BCLC (Barcelona Liver Clinic) 0 and A. RFA challenges surgical resection for small HCC and is the method of choice in bridging for transplantation and recurrence after resection or transplantation. The technical feasibility of RFA depends on the size and location of the HCC and the availability of ablation techniques (one needle techniques, multi-needle techniques). More recently, stereotactic multi-needle techniques with 3D trajectory planning and guided needle placement substantially improve the spectrum of treatable lesions including large volume tumors. Treatment success depends on the realization of ablations with large intentional margins of tumor free tissue (A0 ablation in analogy to R0 resection), which has to be documented by fusion of post- with pre-ablation images, and confirmed during follow-up imaging.

    The authors analyzed all cases of thoracic esophagel carcinoma seen from 1980 to 1984 inclusive, plus an additional 22 cases from a pilot study at Wayne State University. Most patients received preoperative combination radiation and chemotherapy. Eighty-nine patients completed treatment (5-fluorouracil, cisplatin, and radiation therapy) as in both the RTOG and SWOG national studies. Of these 89, 39 refused or were not offered planned surgery. Four patients are still alive and well. Fifty patients underwent esophagectomy; 12 patients were free of tumor at esophagectomy, and four of these are alive and well. One patient with a tumor in the resected esophagus alone is still alive. Twenty-two patients were enrolled in the pilot study in which surgery was reserved for salvage, the initial radiation volume was increased, the tumor dose was increased to 5,000 rad give continuously, and chemotherapy was increased to four courses

The findings of selective celiac and/or hepatic arteriography in total 69 cases of confirmed hepatocellular carcinoma, with clinical and laboratory findings, were analyzed. The summarized results are as follows; 1. Among 69 cases od hepatoma, 62 were male and 7 were female with sex ratio of 8.9 : 1. Peak incidence is 5th to 7th decades (72.5%). Epigastric pain, indigestion, and palpable mass in right upper quadrant were common symptoms and sign. Laboratory findings showed elevated serum alkaline phosphatase more than 5 Bodansky unit in 75.4%. Alpha-feto protein was positive in 65.2% of all the patients. 2 All 69 cases were classified into 31 cases of massive type, 22 cases of diffuse type, and 16 cases of nodular type, in accordance with angiographic gross anatomy. The frequency of angiographic findings were hypervascularities and tumor vessels (100%), tumor stainings (98.5%), arteriovenous shunt (71.0%), displacement of intrahepatic arteries (66.7%), vascular lakes and channel (59.4%). Encasement of hepatic artery and portal vein regurgitation was respectively 4 cases. Tumor mass in portal vein were 6 cases and tumor mass in hepatic vein was 1 case. 3. Intraarterial infusion of 5-FU was performed in 15 hepatoma patients, and the results were that angiographic improvement was demonstrated in 3 cases, no improvement in 8 cases, and incomplete infusion in 4 cases. 4. The selective celiac and/or hepatic angiograms are excellent diagnostic tools as well as therapeutic management for intraarterial infusion of anticancerous drugs.

    2016-06-01

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

    Full Text Available Oral squamous cell carcinomas represent 3% of cancers in men and 2% of cancers in women. More than 90% of oral cancer occurs in people older than 45 years Lesions of gingiva account for approximately 10% of the oral squamous cell carcinomas and may present clinically as an area of ulceration, exophytic mass, or red/white speckled patches. The proximity to the underlying periosteum may invite early bone invasion. Carcinoma of gingiva constitutes an extremely important group of neoplasms as the lesion frequently mimics the reactive and inflammatory conditions affecting the periodontium, delaying the diagnosis and making the prognosis of the patient poorer. A rare case of gingival squamous cell carcinoma has been reported here, in a 40 Year old male patient. Careful recording of the case history and results of clinical examination, radiographic, and laboratory investigations, along with a critical review of similar conditions led to the diagnosis, and treatment was initiated.

    Fifty-two cases of oral verrucous carcinoma treated with radiotherapy at the Regional Cancer Centre, Trivandrum, Kerala, India in 1982 were evaluated to determine the distribution within the oral cavity, clinical extent, and effectiveness of radiotherapy in controlling the disease. The most common site was the buccal mucosa. Fifty percent of the patients had clinically negative regional lymph nodes and 33% were in earlier stages (T1, T2, N0, and M0). The overall 3-year no evidence of disease (NED) survival rate was 44%. The 3-year NED survival rate with radium implant was 86%. We cannot comment on anaplastic transformation after radiotherapy because our treatment failures have not been subjected for biopsy concerning this matter. Because the results are comparable with those of well-differentiated squamous cell carcinoma, we think that the treatment policies advocated for oral squamous cell carcinoma are also applicable to oral verrucous carcinoma

    Basal cell carcinoma is the most common skin cancer, characterised by a slow growing behavior, metastasis are extremely rare, and it occurs in less than 0, 1% of all cases. Giant basal cell carcinoma is a rare form of basal cell carcinoma, more aggressive and defined as a tumor measuring more than 5 cm at its largest diameter. Only 1% of all basal cell carcinoma develops to a giant basal cell carcinoma, resulting of patient's negligence. Giant basal cell carcinoma is associated with higher potential of metastasis and even death, compared to ordinary basal cell carcinoma. We report a case of giant basal cell carcinoma metastaticin lung occurring in a 79 years old male patient, with a fatal evolution after one course of systemic chemotherapy. Giant basal cell carcinoma is a very rare entity, early detection of these tumors could prevent metastasis occurrence and improve the prognosis of this malignancy.

    Surgery, when possible, is the treatment of choice for the uncommon endocrine tumours of pancreas. Unresectable cases are usually treated with cytostatic drugs or α-interferon. We describe a patient with unresectable, locally advanced endocrine pancreatic carcinoma (measuring 5 x 5 x 6 cm) that was totally cured by external radiation therapy only (40 Gy). This case together with four cases in the literature indicate that external radiation therapy should be considered in locally unresectable endocrine pancreatic carcinomas. (author)

    Radiotherapy of gastric carcinoma, in contrast to malignant lymphoma, is not commonly in use, until today. Provided that there is a close cooperation between surgeons and radiooncologists, radiotherapy with sufficient, tolerable doses should be considered in any case of complete resection in order to improve the control of subclinical disease as well as cure from cancer. But also in non-resectable carcinoma of the stomach suitable radiotherapeutic approaches may give helpful palliation. (orig.) [de

    Laparoscopic resection of transverse colon carcinoma is technically demanding and was excluded from most of the large trials of laparoscopic colectomy. The aim of this study was to assess the safety, feasibility, and outcome of laparoscopic resection of carcinoma of the transverse colon. A retrospective review was performed to identify patients who underwent laparoscopic resection of transverse colon carcinoma. These patients were compared to patients who had laparoscopic resection for right and sigmoid colon carcinoma. In addition, they were compared to a historical series of patients who underwent open resection for transverse colon cancer. A total of 22 patients underwent laparoscopic resection for transverse colon carcinoma. Sixty-eight patients operated for right colon cancer and 64 operated for sigmoid colon cancer served as comparison groups. Twenty-four patients were identified for the historical open group. Intraoperative complications occurred in 4.5% of patients with transverse colon cancer compared to 5.9% (P = 1.0) and 7.8% (P = 1.0) of patients with right and sigmoid colon cancer, respectively. The early postoperative complication rate was 45, 50 (P = 1.0), and 37.5% (P = 0.22) in the three groups, respectively. Conversion was required in 1 (5%) patient in the laparoscopic transverse colon group. The conversion rate and late complications were not significantly different in the three groups. There was no significant difference in the number of lymph nodes harvested in the laparoscopic and open groups. Operative time was significantly longer in the laparoscopic transverse colectomy group when compared to all other groups (P = 0.001, 0.008, and transverse colectomy, respectively). The results of laparoscopic colon resection for transverse colon carcinoma are comparable to the results of laparoscopic resection of right or sigmoid colon cancer and open resection of transverse colon carcinoma. These results suggest that laparoscopic resection of transverse

    There are still controversies about the therapeutic strategies and subsequent outcome in head and neck Merkel cell carcinoma. Clinicopathological data of 23 Merkel cell carcinomas, 93 cutaneous head and neck squamous cell carcinomas (HNSCCs), 126 malignant melanomas, and 91 primary parotid gland carcinomas were comprehensively analyzed. Merkel cell carcinomas were cytokeratin 20 (CK20)/neuron-specific enolase (NSE)/chromogranin A (CgA)/synaptophysin (Syn)/thyroid transcription factor-1 (TTF-1)/MIB1 immunostained. All Merkel cell carcinomas underwent wide local excision. Parotidectomy/neck dissection was performed in 40%/33% cutaneous Merkel cell carcinoma and 100%/100% in parotid gland Merkel cell carcinoma. Five-year recurrence-free interval (RFI)/overall survival (OS) was significantly higher in malignant melanoma (81/80%) than in cutaneous Merkel cell carcinoma/HNSCC. Interestingly, 5-year RFI/OS was significantly higher in Merkel cell carcinoma (61%/79%) than in HNSCC (33%/65%; p Merkel cell carcinoma and parotid gland carcinomas, nor in the immunohistochemical profile. Five-year RFI/OS was significantly better in cutaneous Merkel cell carcinoma when compared with TNM classification matched HNSCC. Five-year RFI/OS was comparable in parotid gland Merkel cell carcinoma and other primary parotid gland malignancies. © 2016 Wiley Periodicals, Inc.

    With Development of Computed Tomography, detection of the Hepatocellular Carcinoma are easily performed and frequently used in the world. During 15 months, from December 1985 to February 1987, 59 patients with hepatocellular carcinoma were evaluated with computed tomography in department of radiology at Wallace Memorial Baptist Hospital. The results were as follow: 1. The most prevalent age group was 5th to 7th decades, male to female ratio was 4.9:1. 2. Classification with incidence of computed tomographic appearance of the hepatocellular carcinoma were solitary type 28 cases (48%), multinodular type 24 cases (40%), and diffuse type 7 cases (12%), Association with liver cirrhosis was noted in 22 cases (38%). 3. Inhomogenous internal consistency of hepatocellular carcinoma due to central necrosis were 35 cases (60%). Portal vein invasion by hepatocellular carcinoma was noted in 15 cases (25%), and particularly most common in diffuse type 4 cases (55%). 4. On precontrast scan, all hepatocellular carcinoma were seen as area of low density except for 3 cases(0.5%) of near isodensity which turned out to be remarkable low density on postcontrast scan. 5. In solitary type, posterior segment of right lobe was most common site of involvement 12 cases (43%). In diffuse type, bilobar involvement was most common, 6 cases (85%)

    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.

    A 51-year-old woman had a 35 mm circumscribed calcified lesion identified on screening mammography, designated R4. Excision showed a fibroadenoma with multiple foci of lobular neoplasia (atypical lobular hyperplasia and classical lobular carcinoma in situ [LCIS]). A focus of microinvasive lobular carcinoma (MILC) was also present, confirmed on immunohistochemistry. The MILC cells were ER positive, Her-2-negative, and e-cadherin negative. Microinvasive carcinoma, defined as "invasive carcinoma with no focus measuring >1 mm" (TNM UICC 7th edition) is usually encountered in ductal carcinoma in situ but may occur with classical, florid, or pleomorphic LCIS. In one series MILC constituted 0.4% of all invasive lobular carcinomas and was present in 0.4% of all LCIS. MILC is a histologically subtle lesion, the identification of which lends further weight to the concept of lobular neoplasia as a precursor lesion. MILC has been observed in hamartoma but, to our knowledge, has not previously been reported in fibroadenoma.

    The biological behavior of ulcer type gastric carcinoma was studied on 114 cases of diffuse carcinoma (Borrmann's 4 type) and 262 cases of early like advanced carcinoma (including superficial spreading type). In both types of gastric carcinoma, the age distribution, location, ulcer with cancer focus and prognosis differed greatly. The early like carcinoma was speculated to have advanced maintaining the groos findings of early gastric carcinoma, and its location and associated ulcer were the same as the early ulcer type of carcinoma. The prognosis of this type of carcinoma was good, showing a figure of 70% in 3 year survival rate. On the other hand, diffuse carcinoma demonstrated diffuse extensive infiltration of tumor cells along the gastric wall, resulting in poor prognosis with a 3 year survival rate of almost 0%. Histologically, diffuse type of carcinoma showed lymphatic infiltration of tumor cells, and this is probably the main reason for the diffuse infiltration in this type of carcinoma. Diffuse carcinoma is, therefore, considered to be one special type of carcinoma having different biological behavior compared with the other ulcer type of carcinoma, and diffuse carcinoma is not the terminal stage of early like advanced carcinoma. There are three stages in diffuse carcinoma: 1. Infiltrative stage: wide spread infiltration of cancer cells through lymphatic channels (lymphangiosis carcinomatosa) 2. Edematous stage: soluble collagen appearing in gastric wall 3. Sclerosing stage: soluble collagen changing into insoluble collagen leading to marked thickening and stiffness of the gastric wall. This is the end stage of gastric diffuse carcinoma. It is difficult to explain that the marked fibrosis of gastric wall is a result to stromal reaction from tumor cell infiltration, since extensive fibrosis is found in areas without tumor cells and stiffness of the gastric wall occurs in a too short period of time. The production of abundunt soluble collagen is probably

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

    Lobular carcinoma in situ (LCIS) is a known risk factor for invasive breast carcinoma, but there is increasing data indicating a possible precursor relationship. This study investigates the incidence of lobular carcinoma in situ that occurs with invasive lobular carcinoma (ILC). Women diagnosed with ILC or LCIS from 2000 to 2010 were retrospectively identified and reviewed after institutional review board approval. This group was divided into two cohorts: ILC alone, and LCIS and ILC (ILC/LCIS). Patient demographics, disease characteristics, and treatment modalities were captured. p invasive ductal carcinoma at ∼40%. The association of pre-invasive and invasive lobular lesions should be further studied in a large scale prospective study to assess for a precursor relationship. Copyright © 2014 Elsevier Ltd.

    Collision tumor is an extremely rare tumor which defined as the concrescence of two distinct primaries neoplasms. We report here a case of collision tumor at lower third esophagus composed of small cell type neuroendocrine carcinoma (NEC), which is an very rare, highly aggressive and poorly prognostic carcinoma and squamous cell carcinoma (SqCC). In our case, pathologically, the small cell carcinoma display the characteristic of small, round, ovoid or spindle-shaped tumor cells with scant cytoplasm, which colliding with a moderately differentiated squamous cell carcinoma. Immunohistochemical staining demonstrated positive activities for CD56, synaptophysin, 34βE12, CK 5/6, ki-67 (70%-80%), but negative for CD99, chromogranin A, and TTF-1. Accurate diagnosis was made base on these findings. PMID:24817981

    Introduction: The commonest clinical presentation in majority of breast pathology is a lump. A definite diagnosis of breast lump is very important for the surgeon to decide on the final course of treatment and also saves the patient from unnecessary physical, emotional and psychological trauma if there is a definite preoperative diagnosis of benign lesion. The present study was done to evaluate the effectiveness and relevance of “TRIPLE TEST”in diagnosis of carcinoma breast in rural labour class population. Materials and Methods: The present study was a prospective study conducted on patients over 35 years of age having palpable breast lumps presenting in the out patient department of general surgery, ESI Hospital Basaidarapur New Delhi, India. The duration of study was from May 2007 to June 2009 and a total of 100 cases were studied. Each patient was subjected to a detailed history, clinical breast examination ,diagnostic mammography and FNAC. In this study, the results of each modality was divided in three groups: benign, suspicious and malignant. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of each test was calculated individually and as combined. Result: Out of 100 patients enrolled in this study, 60 cases were benign and 40 cases were of malignant breast disease. The age of patients with carcinoma breast in the series varied from 35 years to 70 years. The highest incidence of malignancy noted was 30% in 41-50 years age group (4th decade) followed by 27.5% in 51-60 years age group (5th decade). The sensitivity of clinical examination was found to be 75%, specificity was 83.3%, positive predictive value (PPV) of 75% and diagnostic accuracy of 80%. The sensitivity, specificity, positive predictive value and diagnostic accuracy of mammography was calculated and was found to be 94.9% , 90% , 86% and 92% respectively.

    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.

    Low-grade salivary duct carcinoma (LG-SDC) is a rare neoplasm characterized by predominant intraductal growth, luminal ductal phenotype, bland microscopic features, and favorable clinical behavior with an appearance reminiscent of florid to atypical ductal hyperplasia to low grade intraductal breast carcinoma. LG-SDC is composed of multiple cysts, cribriform architecture with "Roman Bridges", "pseudocribriform" proliferations with floppy fenestrations or irregular slits, micropapillae with epithelial tufts, fibrovascular cores, and solid areas. Most of the tumor cells are small to medium sized with pale eosinophilic cytoplasm, and round to oval nuclei, which may contain finely dispersed or dark condensed chromatin. Foci of intermediate to high grade atypia, and invasive carcinoma or micro-invasion have been reported in up to 23 % of cases. The neoplastic cells have a ductal phenotype with coexpression of keratins and S100 protein and are surrounded by a layer of myoepithelial cells in non-invasive cases. The main differential diagnosis of LG-SDC includes cystadenoma, cystadenocarcinoma, sclerosing polycystic adenosis, salivary duct carcinoma in situ/high-grade intraductal carcinoma, and papillary-cystic variant of acinic cell carcinoma. There is no published data supporting the continuous classification of LG-SDC as a variant of cystadenocarcinoma. Given that most LG-SDC are non-invasive neoplasms; the terms "cribriform cystadenocarcinoma" and LG-SDC should be replaced by "low-grade intraductal carcinoma" (LG-IDC) of salivary gland or "low-grade intraductal carcinoma with areas of invasive carcinoma" in those cases with evidence of invasive carcinoma.

    To describe the clinico-pathological and radiological profile of hepatocellular carcinoma. All consecutive patients suspected of having hepatocellular carcinoma (HCC), were admitted and included in this study. Diagnosis of HCC was established by clinical, biochemical, ultrasonographic and histopathologic findings. Patients with primary carcinoma elsewhere in the body, metastatic in the liver, fibrolamellar carcinoma and benign tumours were excluded from the study. At ultrasonography, the details of tumour size and number, portal vein thrombosis and presence of ascites were recorded. Patients were staged according to Okuda staging system. Results were described in mean and percentage values. There were 82 patients with hepatocellular carcinoma including 58 males and 24 females, with male to female ratio of 2.8:1. The mean age of patients was 56.24 +- 13.65 years. Right hypochondrial pain was the main symptom in 52 (63.4%) patients. The duration of symptoms varied from 1 month to 2 years. Tumour size was larger than 50% of liver size in 42 (51.2%) with portal vein thrombosis in 10 (12.19%). Anti HCV was positive in 44 (53.7%), HBsAg in 26 (31.7%) and both were found positive in 2 (2.44%) patients. Ten patients (12.2/%) found negative both for anti-HCV and HBsAg. According to Okuda staging system 18 patients had stage 1, 50 had stage 2 and 14 had stage 3 hepatocellular carcinoma. The mean age of presentation of hepatocellular carcinoma was younger as compared to western countries with potentially large non-resectable lesions. Chronic hepatitis C and B was found to be the major known factors. Patients with chronic hepatitis C and B should undergo vigorous HCC surveillance to detect early, potentially respectable HCC.

    The management of head and neck cancer has evolved into a multidisciplinary approach in which patients are evaluated before treatment and decisions depend on prospective multi-institutional trials, as well as retrospective outcome studies. The choice of one or more modalities to use in a given case varies with the tumor site and extent, as exemplified in the treatment of laryngeal squamous cell carcinomas. The goals of treatment include cure, laryngeal voice preservation, voice quality, optimal swallowing, and minimal xerostomia. Treatment options include transoral laser excision, radiotherapy (both definitive and postoperative), open partial laryngectomy, total laryngectomy, and neck dissection. The likelihood of local control and preservation of laryngeal function is related to tumor volume. Patients who have a relatively high risk of local recurrence undergo follow-up computed tomography scans every 3-4 months for the first 2 years after radiotherapy. Patients with suspicious findings on computed tomography might benefit from fluorodeoxyglucose positron emission tomography to differentiate post-radiotherapy changes from tumor

    Since 1969, preoperative irradiation of hypernephiroid carcinoma has been a routine measure at the Steglitz medical clinic: It consists in the application of a focal dose of 30 Gy, fractionated into doses of 2.5 Gy, as Betatron pendulum irradiation (42 MeV photons) covering the para-aortic lymph nodes. After a treatment-free interval of 3 weeks, radical nephrectomy is carried through. Of 178 patients, 47 were in tumor stage I, 15 in stage II, 83 in stage III and 33 in stage IV. In 99 patients the treatment dated back longer than 5 years; the survival rate was 52%. 67% of the patients had survived longer than 3 years. Operation lethality was 3%. The preoperative irradiation pursues the following aims: 1. Devitalization of potentially proliferating cells in the tumor periphery, and thus prevention of displaced tumor cells growing on and postoperative local recidivations; 2. Shrinking of the tumor, facilitating the surgical intervention. In a third of the cases a measurable alteration of the tumor was confirmed by X-ray. The low operation lethality of 3% is attributed to this. (orig./MG) [de

    In this study, we retrospectively reviewed the MRI features of recurrent nasopharyngeal carcinoma (NPC) in 72 patients who underwent MRI before and after gadolinium injection. Recurrent NPC exhibited a high degree of regional spread and a variety of signal intensities and contours. MRI showed a nasopharyngeal mass in 50 patients (69.4 %); other sites of involvement included the parapharyngeal space (44.4 %), nasal cavity (12.5 %), paranasal sinuses (27.8 %), oropharynx (4.2 %), orbit (8.3 %), infratemporal fossa (18.1 %), skull base (59.8 %), intracranial area (51.4 %) and regional lymph nodes (15.3 %). On T2-weighted images, the nasopharyngeal mass gave high signal in 9 of 50 cases (18 %), intermediate in 27 (54 %), mixed in 8 (16 %) and low signal in 6 (12 %). Contrast enhancement was strong in 12 cases (24 %), moderate in 29 (58 %) and heterogeneous in 9 (18 %). The lesion was convex in 31 cases (62 %) and concave or straight in 19 (38 %). Recognition of the distribution and the appearance of recurrent NPC on MRI is essential for timely diagnosis and appropriate treatment. (orig.)

    Hepatocellular carcinoma (HCC) is frequently diagnosed at advanced stages and has a high mortality rate. With improved survival of patients with cirrhotic liver disease and increased prevalence of chronic hepatitis C viral infections, a rise in the number of HCC cases is being reported worldwide. Early diagnosis and treatment can significantly improve the prognosis of patients with HCC. Although surgical resection is an important potentially curative therapy for liver tumors, in appropriately selected patients, liver transplantation has been shown to achieve excellent survival rates for a solid tumor. Locally ablative and locoregional therapies in the form of percutaneous ethanol injection, radiofrequency ablation, transcatheter arterial chemoembolization and transcatheter arterial radioembolization (TheraSphere) are viable options in patients with unresectable HCC. Unfortunately, the role of systemic therapy has been very limited in the treatment of these patients. Novel treatment options based on an improved understanding of the molecular pathogenesis of HCC are being explored. These targeted molecular therapies are aimed at growth factors and their receptors, intracellular signal transduction and cell cycle control. A substantial improvement in outcomes of intermediate and advanced stage HCC is expected with the advent of these targeted therapies, used in combination with surgical or locoregional therapies. Recent positive results from a large Phase III study of the receptor tyrosine kinase inhibitor, sorafenib, hold great promise in the treatment of HCC.

    Full Text Available Invasive lobular carcinoma is the second most common type of invasive breast cancer accounting for approximately 5-10% of all invasive breast carcinomas. The metastatic patterns of lobular and ductal carcinomas are significantly different. Most series report a greater propensity for lobular carcinoma to metastasize to the gastrointestinal tract, gynecological organs and the peritoneum, while ductal carcinoma most frequently relapses in the liver, lungs and the brain. Gastrointestinal system metastases were observed in 6-18%, the most commonly affected organ is the stomach. We aimed to present a female patient who had been diagnosed with invasive lobular carcinoma of the breast ten years ago and had invasive ductal carcinoma of the other breast three years ago, investigated for excessive ascites and found to have invasive lobular breast carcinoma metastasis to the stomach.

    The pancreas is an unusual site for tumor metastasis, accounting for only 2% to 5% of all malignancies affecting the pancreas. The more common metastases affecting the pancreas include renal cell carcinomas, melanomas, colorectal carcinomas, breast carcinomas, and sarcomas. Although pancreatic involvement by nonrenal malignancies indicates widespread systemic disease, metastatic renal cell carcinoma to the pancreas often represents an isolated event and is thus amenable to surgical resection, which is associated with long-term survival. As such, it is important to accurately diagnose pancreatic involvement by metastatic renal cell carcinoma on histology, especially given that renal cell carcinoma metastasis may manifest more than a decade after its initial presentation and diagnosis. In this review, we discuss the clinicopathologic findings of isolated renal cell carcinoma metastases of the pancreas, with special emphasis on separating metastatic renal cell carcinoma and its various differential diagnoses in the pancreas.

    Full text: The incidence of thyroid cancer has been in linear increase for several decades because of the evolution and the generalization of the means of diagnosis. The objective of our work is to carry out an epidemiologic approach of differentiated thyroid carcinoma in our country, with an evaluation of the recent review of literature. Materials and methods: Our work consists of a retrospective analysis of 3144 cases of differentiated thyroid carcinoma, followed in nuclear medicine department of Ibn Sina hospital in Rabat for a period of 12 years. Our evaluation parameters related to the incidence of thyroid carcinoma are age of onset, sex, size of tumor, histological type, evolution and risk factors. Results: The incidence of differentiated thyroid carcinoma was estimated in our country at 0,8 by 100000 inhabitants per year. The sex ratio was evaluated at 3,5/1 whereas the average age was 42,5 years. Papillary carcinoma represented 65,58 %, well differentiated follicular carcinoma 21,92 % and moderately differentiated carcinoma to 12,5%. The microcarcinomas were estimated at 8,1 %. The size of tumor at the time of diagnosis was higher than 2 cm in 70% of cases. The lymphatic extension was objectified in 47,6 % of papillary forms and 3,5 % of follicular carcinoma. Remote metastasis was found in 0,8 % of cases between 30 and 40 years and 4,71 % after the age of 40 years. Discussion: The cancer of thyroid is not very frequent. Indeed, its annual incidence throughout the world is 0,5 to 10 by 100.000 inhabitants with a clear female prevalence. The majority of cases occur between 15 and 50 years. This cancer is very rare in children less than 15 years. In Morocco, the incidence has increased these last decades like many countries in the world (0,8 by 100.000 inhabitants per year). We note, in addition, an increase in the prevalence of papillary microcarcinoma seeing the improvement of early tracking methods (echography, fine needle aspiration biopsy). The risk

    A total of 25 cases with early gastric carcinoma, of which 10 cases were followed by gastrectomy, were given a combined radiotherapy with 5-Fu, Ft 207 or MFC at Miyagi Seijinbyo Center. Histologic examinations of biopsy specimens revealed the disappearance of cancer cells in five (42%) of 12 cases and those of serial specimens of the resected stomach showed the complete disappearance of cancer cells in three (27%) of 11 lesions (10 cases). Five year survival rate in 15 non-resected cases was only 30%. From these results, it was suggested that a combined radiotherapy of early gastric carcinoma should not be chosen as a curative treatment procedure but it might be valuable, if early carcinoma was thought to be inoperable because of other medical reasons.

    Full Text Available BACKGROUND Oesophageal cancer is a serious malignancy with regards to mortality and prognosis. It is a growing health concern that is expected to increase in incidence over the next 10 years. Squamous cell carcinoma is the most common histological type of oesophageal cancer worldwide with a higher incidence in developing nations. With the increased prevalence of gastroesophageal reflux disease and obesity in developed nations, the incidence of oesophageal adenocarcinoma has dramatically increased in the past 40 years. MATERIALS AND METHODS Retrospective study was conducted to study the clinical profile of patients presented with oesophageal carcinoma at Government Medical College, Kottayam, Kerala, India, during January 1, 2015, to December 31, 2016. 104 subjects who met the inclusion criteria were enrolled. Data were collected from the records. RESULTS Out of 104 subjects enrolled in the study, 78 (75% were males, rest 26 (25% were females. 73% of the patients with oesophageal carcinoma were above 60 years. 79.8% patients presented with dysphagia. 87.5% cases had squamous cell type lesions. More than 75% of the lesions were in the mid and lower oesophagus. Noduloulcerative type was the most common morphologic presentation. CONCLUSION Squamous cell carcinoma is the most common oesophageal carcinoma in our institution. Majority of the lesions are located in the mid and lower oesophagus and are well differentiated.

    In this paper, we describe the new imaging modalities employed in initial imaging management of renal carcinoma which provide accurate answers to practical questions. This article highlights the more suitable diagnostic imaging tools, their strong and weak points, their limitations with emphasis placed on the major role of helical CT in diagnosis and initial staging of renal carcinoma: helical CT allows complete examination in the same time of the lesion and its possible extensions. In recent years with the advent of new imaging modalities, HelicalCT has become the standard diagnostic method for characterizing and staging renal carcinoma which decisively influences the therapeutic approach. CT can diagnose the type of carcinoma, precisely establish local and regional staging such as extension to the adjacent structures (perirenal fat, collecting system), presence of regional lymph node metastases and venous tumor thrombus. In addition helical CT is able to detail anatomical landmarks (venous and arterial) necessary for partial nephrectomy. This article points out the various key points in detection mid work-up of a renal carcinoma required for proper therapeutic decision-making. (authors)

  1. Epigenetic Dysregulation in Laryngeal Squamous Cell Carcinoma

    2012-01-01

    Full Text Available Laryngeal carcinoma is a common head and neck cancer with poor prognosis. Patients with laryngeal carcinoma usually present late leading to the reduced treatment efficacy and high rate of recurrence. Despite the advance in the use of molecular markers for monitoring human cancers in the past decades, there are still no reliable markers for use to screen laryngeal carcinoma and follow the patients after treatment. Epigenetics emerged as an important field in understanding the biology of the human malignancies. Epigenetic alterations refer to the dysregulation of gene, which do not involve the alterations of the DNA sequence. Major epigenetic changes including methylation imbalance, histone modification, and small RNA dysregulation could play a role in the development of human malignancies. Global epigenetic change is now regarded as a molecular signature of cancer. The characteristics and behavior of a cancer could be predicted based on the specific epigenetic pattern. We here provide a review on the understanding of epigenetic dysregulation in laryngeal carcinoma. Further knowledge on the initiation and progression of laryngeal carcinoma at epigenetic level could promote the translation of the knowledge to clinical use.

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

    The Epstein-Barr virus (EBV) is detected in about 10% of gastric carcinoma cases throughout the world. In EBV-associated gastric carcinoma, all tumor cells harbor the clonal EBV genome. Gastric carcinoma associated with EBV has distinct clinicopathological features, occurs predominately in men and in younger-aged individuals, and presents a generally diffuse histological type. Most cases of EBV-associated gastric carcinoma exhibit a histology rich in lymphocyte infiltration. The immunological reactiveness in the host may represent a relatively preferable prognosis in EBV-positive cases. This fact highlights the important role of EBV in the development of EBV-associated gastric carcinoma. We have clearly proved direct infection of human gastric epithelialcells by EBV. The infection was achieved by using a recombinant EBV. Promotion of growth by EBV infection was observed in the cells. Considerable data suggest that EBV may directly contribute to the development of EBV-associated GC. This tumor-promoting effect seems to involve multiple mechanisms, because EBV affects several host proteins and pathways that normally promote apoptosis and regulate cell proliferation.

    Adenocystic carcinoma most commonly develops in the major salivary glands, on the other hand it is rare for adenocystic carcinoma to develop in the larynx. We report a case of adenocystic carcinoma in the larynx. A 54-year-old male was hospitalized with symptoms of hoarseness and dyspnea on exertion. He presented a tumor that developed at the base of the right arytenoid, and covered over the glottis. It was confirmed to be adenocystic carcinoma (solid type) by biopsy. Positron emission tomography (PET)-CT also revealed a left cervical lymph node metastasis and multiple pulmonary metastases (T1N2cM1). He was treated with proton therapy to the larynx to prevent airway obstruction by growth of the tumor and to preserve the larynx because he had uncontrollable pulmonary metastasis. Although the tumor vanished after the treatment, one month later he had halitosis, dyspnea and bilateral vocal cord palsy. Despite administration of an antibacterial drug and steroid, there was no improvement to the narrowness of the glottis. A tracheotomy was therefore performed three months after the proton therapy. PET-CT, which was performed after the tracheotomy, suggested growth of the residual tumor or laryngeal radionecrosis. This study confirmed that proton therapy is effective for adenocystic carcinoma in the larynx. However, proton therapy also was found to cause laryngeal radionecrosis. These results indicate the importance of evaluating the side effects of radiation therapy and providing that information to the patient. (author)

    The Epstein-Barr virus (EBV) is detected in about 10% of gastric carcinoma cases throughout the world. In EBV-associated gastric carcinoma, all tumor cells harbor the clonal EBV genome. Gastric carcinoma associated with EBV has distinct clinicopathological features, occurs predominately in men and in younger-aged individuals, and presents a generally diffuse histological type. Most cases of EBV-associated gastric carcinoma exhibit a histology rich in lymphocyte infiltration. The immunological reactiveness in the host may represent a relatively preferable prognosis in EBV-positive cases. This fact highlights the important role of EBV in the development of EBV-associated gastric carcinoma. We have clearly proved direct infection of human gastric epithelialcells by EBV. The infection was achieved by using a recombinant EBV. Promotion of growth by EBV infection was observed in the cells. Considerable data suggest that EBV may directly contribute to the development of EBV-associated GC. This tumor-promoting effect seems to involve multiple mechanisms, because EBV affects several host proteins and pathways that normally promote apoptosis and regulate cell proliferation

    Full Text Available Objective. Black thyroid is a rare pigmented change seen almost exclusively in patients upon minocycline ingestion, and the process has previously been thought to be generally benign. There have been 61 reported cases of black thyroid. We are aware of 13 cases previously reported in association with thyroid carcinoma. This paper reports six patients with black thyroid pigmentation in association with thyroid carcinoma. Design. The medical records of six patients who were diagnosed with black thyroid syndrome, all of whom underwent thyroid surgery, were reviewed. Data on age, gender, race, preoperative fine needle aspiration biopsy (FNA, thyroid function levels, and pathology reports were collected. Main Outcome. The mean age was 60 years. There were 5 females, 4 of whom were African American. All patients were clinically and biochemically euthyroid. Black pigmentation was not diagnosed in preoperative FNA, and only one patient had a preoperative diagnosis of papillary thyroid carcinoma. The other patients underwent surgery and were found to have black pigmentation of the thyroid associated with carcinoma. Conclusions. FNA does not diagnose black thyroid, which is associated with thyroid carcinoma. Thyroid glands with black pigmentation deserve thorough pathologic examination, including several sections of each specimen.

    Accurate staging as well as diagnosis of cervix carcinoma is of paramount importance in planning treatment. Cervical smear cytologic studies have increased the detection rate of cervix carcinoma, but current radiologic techniques are limited in staging cervix carcinoma and precise visualization of lymphnodal metastasis. The CT scan can display the precise transaxial anatomical structures, permitting us not only to know the tumor size, shape and its extent but also lymphnodal enlargement in the pelvic cavity and around the abdominal aorta and secondary changes of the kidney. The authors have tested the usefulness of CT in staging cervix carcinoma and detecting lymphatic involvement by analysis of 24 cases diagnosed by CT and confirmed histologically at St. Mary's hospital during the period from October 1982 to May 1984. The conclusions are as follows: 1. The accuracy of CT in staging of cervix carcinoma was 79%. 2. The accuracy of CT diagnosis of lymphatic involvement was 87.5%, sensitivity was 85.7%, and specificity was 88.2%

    Full Text Available Urachal carcinoma is rare comprising less than 1% of all bladder carcinomas. Metastases of urachal carcinoma have been reported to meninges, brain, ovary, lung, and maxilla. Cytologic features of metastatic urachal carcinoma have not been previously reported. We present a case of metastatic urachal adenocarcinoma in bronchial brushings and review the use of immunohistochemistry in its diagnosis. A 47-year-old female was seen initially in 2007 with adenocarcinoma of the bladder dome for which she underwent partial cystectomy. She presented in 2011 with a left lung mass and mediastinal adenopathy. Bronchoscopy showed an endobronchial lesion from which brushings were obtained. These showed numerous groups of columnar cells with medium sized nuclei and abundant cytoplasm. The cells were positive for CK20 and CDX2 and negative for CK7. The cytomorphological findings were similar to those in the previous resection specimen and concurrent biopsy. This is the first case report of bronchial brushings containing metastatic urachal carcinoma. No specific immunohistochemical profile is available for its diagnosis. The consideration of a second primary was a distinct possibility in this case due to the lapse of time from primary resection, absence of local disease, and lack of regional metastases.

    Of patients examined during the 24 years from January 1963 to December 1986, we have reviewed 6116 cases of gastric cancer. We found 126 cases of gastric carcinoma in patients below 30 years of age among 6116 cases of gastric malignancy, which were confirmed by histopathological study at PMC in Chonju. In an attempt to identify further the natural history of carcinoma of the stomach in young adults, we reviewed 126 cases of stomach carcinoma in patients below 30 years of age at PMC. The results were as follows: 1.Among the gastric malignancies the incidence of gastric carcinoma in young adults was 2.1%. 2.The age ranged from 13 years to 29 years, and the peak incidence occurred in the 3rd decade. 3.Male to female ratio was 1:1.03. 4.Common symptoms included epigastric pain, indigestion, weight loss, and vomiting. The mean time interval between onset of symptoms and the 1st visit to a physician was 12 months. 5.Usually diagnostic aids were UGI series, endoscopic examination and biopsy. 6.In the endoscopic finding Borrmamn type III was predominant. 7.The majority of tumors occurred in the antrum and Pyloric portion. 8.Histologic diagnosis were adenocarcinoma, signet ring cell carcinoma, and mucinous cardinoma, in orders

    Adenosquamous carcinoma, a rare malignant tumor of the stomach, is characterized by the presence of two different cell components, one adenomatous and the other squamous. Adenosquamous carcinoma of the stomach tends to more aggressive clinicopathologic features than common adenocarcinoma. There are few reports about radiologic features of adenosquamous carcinoma of the stomach. We experienced a case of a primary adenosquamous carcinoma of the stomach in a 67-year-old man, and report here the ultrasonographic and computed tomographic (CT) findings

    2011-01-01

    Canine prostatic tumours exhibit similarities to those of man and may represent a useful model system to explore the mechanisms of cancer progression. Tumour progression to malignancy requires a change from an epithelial phenotype to a fibroblastic or mesenchymal phenotype. Vimentin expression...... is associated with the invasive phenotype of human prostate cancer cells. The aim of the present study was to characterize immunohistochemically the expression of vimentin by canine prostatic carcinomas. Primary carcinomas and metastatic tumour foci both showed vimentin expression. This finding suggests...... that the acquisition of the epithelial-mesenchymal transition phenotype in canine prostatic carcinoma may be characterized by the presence of mesenchymal intermediate filament (vimentin) that could lead to a higher likelihood of metastasis....

    Metastatic renal cell carcinoma of the nasopharynx, nasal cavity, and paranasal sinuses can be misdiagnosed as primary malignant or benign diseases. A 33-year-old male attended our outpatient clinic complaining of difficulty breathing through the nose, bloody nasal discharge, postnasal drop, snoring, and discharge of phlegm. Endoscopic nasopharyngeal examination showed a vascularized nasopharyngeal mass. Under general anesthesia, multiple punch biopsies were taken from the nasopharynx. Pathologically, the tumor cells had clear cytoplasm and were arranged in a trabecular pattern lined by a layer of endothelial cells. After the initial pathological examination, the pathologist requested more information about the patient's clinical status. A careful history revealed that the patient had undergone left a nephrectomy for a kidney mass diagnosed as renal cell carcinoma 3 years earlier. Subsequently, nasopharyngeal metastatic renal cell carcinoma was diagnosed by immunohistochemical staining with CD10 and vimentin. Radiotherapy was recommended for treatment.

    - Basal cell carcinoma (BCC) is the most common human malignant neoplasm and is a frequently encountered diagnosis in dermatopathology. Although BCC may be locally destructive, it rarely metastasizes. Many diagnostic entities display morphologic and immunophenotypic overlap with BCC, including nonneoplastic processes, such as follicular induction over dermatofibroma; benign follicular tumors, such as trichoblastoma, trichoepithelioma, or basaloid follicular hamartoma; and malignant tumors, such as sebaceous carcinoma or Merkel cell carcinoma. Thus, misdiagnosis has significant potential to result in overtreatment or undertreatment. - To review key features distinguishing BCC from histologic mimics, including current evidence regarding immunohistochemical markers useful for that distinction. - Review of pertinent literature on BCC immunohistochemistry and differential diagnosis. - In most cases, BCC can be reliably diagnosed by histopathologic features. Immunohistochemistry may provide useful ancillary data in certain cases. Awareness of potential mimics is critical to avoid misdiagnosis and resulting inappropriate management.

    Primary intraosseous carcinoma (PIOC) is a rare odontogenic carcinoma defined as a squamous cell carcinoma arising within a jaw having no initial connection with the oral mucosa, and presumably developing from residues of the odontogenic epithelium. A 56-year-old patient who complained of delayed healing after extraction of upper left central incisor visited our department. The conventional radiographs showed a bony destructive lesion with ill-defined margin and moth-eaten appearance. On the computed tomographic images, the lesion perforated the labial cortex of alveolar bone, elevated the left nasal floor superiorly, and perforated partially both nasal floor. The magnetic resonance images showed low signal intensity at T2 and T1 weighted images at the area and adjacent soft tissue. Histologically, there were irregular epithelial islands with cell atypia, nuclear hyperchromatism, pleomorphism, atypical mitosis. The final diagnosis was PIOC.

    Primary squamous cell carcinoma of the stomach is very rare. Its pathogenesis is unclear and the treatment strategy is controversial. We report an agressive primary squamous cell carcinoma of the stomach with liver and lung metastases in a 55-year-old man. The patient presented with a 1-month history of abdominal pain, vomiting and weight loss. Abdominal ultrasound revealed multiple liver metastases. Endoscopic examination showed two tumour masses on the fundus of the stomach. Biopsy of the lesions revealed squamous cell carcinoma of the stomach. Chest x-ray showed multiple large pulmonary nodules highly suggestive of pulmonary metastases. The patient died ten days after he was admitted because of progression of the tumour and before any therapeutic decision.

    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)

    2017-01-01

    Hepatocellular carcinoma (HCC) is a major cause of cancer-related death worldwide. In select patients, surgical treatment in the form of either resection or transplantation offers a curative option. The aims of this review are to (1) review the current American Association for the Study of Liver Diseases/European Association for the Study of the Liver guidelines on the surgical management of HCC and (2) review the proposed changes to these guidelines and analyze the strength of evidence underlying these proposals. Three authors identified the most relevant publications in the literature on liver resection and transplantation for HCC and analyzed the strength of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) classification. In the United States, the liver allocation system provides priority for liver transplantation to patients with HCC within the Milan criteria. Current evidence suggests that liver transplantation may also be indicated in certain patient groups beyond Milan criteria, such as pediatric patients with large tumor burden or adult patients who are successfully downstaged. Patients with no underlying liver disease may also benefit from liver transplantation if the HCC is unresectable. In patients with no or minimal (compensated) liver disease and solitary HCC ≥2 cm, liver resection is warranted. If liver transplantation is not available or contraindicated, liver resection can be offered to patients with multinodular HCC, provided that the underlying liver disease is not decompensated. Many patients may benefit from surgical strategies adapted to local resources and policies (hepatitis B prevalence, organ availability, etc). Although current low-quality evidence shows better overall survival with aggressive surgical strategies, this approach is limited to select patients. Larger and well-designed prospective studies are needed to better define the benefits and limits of such approach. PMID:28975836

    Hepatocellular carcinoma (HCC) is the leading cause of deaths in cirrhotic patients and the third cause of cancer related deaths. Most HCC are associated with well known underlying risk factors, in fact, HCC arise in cirrhotic patients in up to 90% of cases, mainly due to chronic viral hepatitis and alcohol abuse. The worldwide prevention strategies are conducted to avoid the infection of new subjects and to minimize the risk of liver disease progression in infected patients. HCC is a condition which lends itself to surveillance as at-risk individuals can readily be identified. The American and European guidelines recommended implementation of surveillance programs with ultrasound every six months in patient at-risk for developing HCC. The diagnosis of HCC can be based on non-invasive criteria (only in cirrhotic patient) or pathology. Accurately staging patients is essential to oncology practice. The ideal tumour staging system in HCC needs to account for both tumour characteristics and liver function. Treatment allocation is based on several factors: Liver function, size and number of tumours, macrovascular invasion or extrahepatic spread. The recommendations in terms of selection for different treatment strategies must be based on evidence-based data. Resection, liver transplant and interventional radiology treatment are mainstays of HCC therapy and achieve the best outcomes in well-selected candidates. Chemoembolization is the most widely used treatment for unresectable HCC or progression after curative treatment. Finally, in patients with advanced HCC with preserved liver function, sorafenib is the only approved systemic drug that has demonstrated a survival benefit and is the standard of care in this group of patients.

    1989-01-01

    Axial CT findings of 56 patients with biopsy-proven nasopharyngeal carcinoma (NPC) were reviewed retrospectively to evaluate the region of origin of the tumor and the sites of spread of the disease. In all patients asymmetry of the mucosal airway contour with blunting of the fossa of Rosenmueller was seen, usually associated with infiltration of the levator palatini muscle. The earliest lesion of NPC arose in this region, and in 64% of cases the tumor had infiltrated into the adjacent parapharyngeal space with loss of its normal fat density. Superior intracranial extension was the most common site of deep infiltration from here (45% of patients) with opacification of the sphenoid sinus in 41% and bony destruction of the skull base in 29%. Invasion into the retropharyngeal space (38%) and carotid space (23%) were the next most common sites of infiltration. Invasion into the prevertebral space was seen in 14%. Anterior spread to the masticator space including the infratemporal fossa was an uncommon finding (14%). T-staging of these patients by CT was also done using both the AJC and Ho classification systems. Lymph node metastases were found in many patients (38%), most commonly in the retropharyngeal nodes, internal jugular nodes including jugular-digastricus nodes and the spinal assessory nodes, respectively. CT remains the most reliable technique for staging and assessing the extent of NPC, both prior to and after radiotherapy, and should be used not only for T-staging of the disease, but also for N-staging. It is recommended that axial scans should be routinely extended down the neck to the clavicles in all patients with NPC. (orig.)

    2016-07-01

    Merkel cell carcinoma (MCC) is a rare and aggressive neuroendocrine tumor of the skin. Early-stage disease can be cured with surgical resection and radiotherapy (RT). Sentinel lymph node biopsy (SLNB) is an important staging tool, as a microscopic MCC is frequently identified. Adjuvant RT to the primary excision site and regional lymph node bed may improve locoregional control. However, newer studies confirm that patients with biopsy-negative sentinel lymph nodes may not benefit from regional RT. Advanced MCC currently lacks a highly effective treatment as responses to chemotherapy are not durable. Recent work suggests that immunotherapy targeting the programmed cell death receptor 1/programmed cell death ligand 1 (PD-1/PD-L1) checkpoint holds great promise in treating advanced MCC and may provide durable responses in a portion of patients. At the same time, high-throughput sequencing studies have demonstrated significant differences in the mutational profiles of tumors with and without the Merkel cell polyomavirus (MCV). An important secondary endpoint in the ongoing immunotherapy trials for MCC will be determining if there is a response difference between the virus-positive MCC tumors that typically lack a large mutational burden and the virus-negative tumors that have a large number of somatic mutations and predicted tumor neoantigens. Interestingly, sequencing studies have failed to identify a highly recurrent activated driver pathway in the majority of MCC tumors. This may explain why targeted therapies can demonstrate exceptional responses in case reports but fail when treating all comers with MCC. Ultimately, a precision medicine approach may be more appropriate for treating MCC, where identified driver mutations are used to direct targeted therapies. At a minimum, stratifying patients in future clinical trials based on tumor viral status should be considered as virus-negative tumors are more likely to harbor activating driver mutations.

  9. Synchronous Parathyroid and Papillary Thyroid Carcinoma

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

    Oral cancer varies globally and regionally, and is closely linked with geographical, social, economical, biological, ethnic, dietary and environmental factors. In western countries it accounts for about 2 - 5% while in the south-east Asia for about 40% of all cancers. In Pakistan it is second commonest tumour after bronchogenic carcinoma in males and breast carcinoma in females. The objectives of this study were to find out the pattern of carcinoma cheek in our region, its etiological associations, management and prognosis. This study was conducted in the Otolaryngology and Head and Neck Surgery Department of Civil Hospital, Karachi from April 1995 to December 1998. It was prospective study. Methods: Forty-five cases of primary carcinoma cheek were diagnosed and investigations including OPG and CT scan were carried out along with other required investigations to evaluate the extension of tumour, bony erosion and metastasis. TNM staging was done. All patients were treated surgically, sent for post-operative radiotherapy or chemo radiation and followed up for 3 years. Result: Among 45 cases of oral cancer, 28 were females and 17 were males. Common presenting symptom was growth or ulcer. It was more common in 41 - 50 years of age. Squamous cell carcinoma (SCC) was found in 95.5% of the cases. Most of the patients 31 (68%) were in T4 stage. Surgical excision was done in all cases with reconstruction in 23 cases and neck dissection in 39 cases. In the follow up for 3 years, 30 patient remained disease free. Conclusion: Carcinoma cheek is a common entity in our region and now it is seen in relatively younger patients. Oral cancer is a self preventable disease. What is required is to develop awareness of oral hygiene and discourage the habit of social carcinogens use. Early diagnosis and treatment offers better chance of cure whereas advance disease has a poor prognosis. (author)

    Full Text Available Inflammatory breast carcinoma is an extremely rare, rapidly progressive breast carcinoma which is a great masquerader and often is mistaken as an inflammatory lesion. This leads to the delay in diagnosis. Here, we report such a case where the mistaken clinical diagnosis led to it being treated with antibiotics. However, fine-needle aspiration cytology of the case saved the day. Histopathological confirmation followed by multimodal therapy was rendered, and the patient responded well to the treatment. Thus, awareness and recognition of this rare entity, which mimics various inflammatory and nonmalignant causes, is of paramount importance for the doctors and patients alike.

    Full Text Available Cutaneous metastases from primary internal malignancies are an uncommon presentation. Cutaneous metastases are more frequently seen in breast cancer than in any other visceral malignancy in women. Medical practitioners should be vigilant of the possibility of unusual presentations of metastatic disease in breast cancer patients with lobular carcinoma presenting as cutaneous lesions mimicking benign dermatological conditions. Herein, we present a case of a 75-year-old woman presenting with cutaneous lobular breast carcinoma metastases on her anterior right leg, which had previously been misdiagnosed as dermatitis for 9 years.

    Metastatic carcinoma to the thyroid gland rarely is encountered in clinical practice; however, autopsy series have shown that it is not a rare occurrence. A case of adenocarcinoma of the colon with metastases to the thyroid is reported. A review of the literature reveals that melanoma, breast, renal, and lung carcinomas are the most frequent tumors to metastasize to the thyroid. Metastatic disease must be considered in the differential diagnosis of cold nodules on radionuclide thyroid scans, particularly in patients with a known primary

    Background. The opinions on the value of adjuvant therapy in choroid plexus carcinomas vary. The aim of present report is to present a case of successful therapy of this rare tumor. Result. A fourteen-year-old girl with third ventricle tumor had non-radical surgery and adjuvant chemotherapy and irradiation. She is alive with no evidence of disease 8.5 years after diagnosis. The role of adjuvant therapy in the context of literature data is discussed. Conclusion. For choroids plexus carcinomas, adjuvant multiagent chemotherapy and craniospinal radiotherapy following surgery should be considered. (author)

    1999-01-01

    For patients with unresectable pancreatic carcinoma, a few kind of treatment including chemoradiation, intraoperative radiation and intra-arterial chemotherapy was done. Chemoradiation using 5FU, CDDP, ADM and radiation to the lesion and liver was performed in 16 patients, showing a response rate of 10%. One-year survivals rate and mean a survival period of this group was 11.7% and 6.6 months respectively. Postmortem autopsy in 6 cases revealed insufficient therapeutic effects in both primary and metastatic site. Because of above-mentioned reasons, chemoradiation therapy to the pancreatic carcinoma, which we did, was estimated as ineffective. (author)

    1987-01-01

    Carcinoma of the endometrium is the most common malignant tumor in the female genital tract. Radiation therapy continues to play a major role in the management of endometrial carcinoma, both as primary therapy and as adjuvant treatment. The utility of pelvic external beam therapy and intracavitary therapy is long established. However, the modern era of surgical staging has lead to an appreciation of the role of radiation therapy beyond the pelvis. Radiation therapy has been shown to be of particular benefit in peritoneal and nodal spread. The classic management of endometrial cancer is reviewed and relatively new and somewhat controversial topics, such as preoperative intracavitary therapy followed by external beam therapy are discussed

    Full Text Available Renal clear cell carcinoma (RCC has different manifestations, including uncommon metastasis and paraneoplastic syndromes. Here we report a rare case of RCC presenting as metastasis to the mandible. A 57-year-old patient with mandibular swelling was referred to the dentist. After necessary evaluations, an incisional biopsy of mandible showed metastatic RCC. The patient was referred to the urologist. The patient underwent right radical nephrectomy. Pathological examination showed clear renal cell carcinoma. Every abnormal bone lesion in the oral cavity should be evaluated carefully and the possibility of a malignant lesion should always be considered.

    2011-12-01

    Full Text Available Gastric carcinoma is frequently diagnosed with an advanced stage of non-curable tumor growth characterized by infiltration of the gastric serosa, peritoneal tumor spread and/or metastases within lymph nodes and liver. Currently, there is a controversy on the value of palliative resection with regard to the safety and benefit to the patient outcome. Based on the available literature, this overview summarizes the various aspects and interprets the limited data on the palliative resection of gastric carcinoma. It turns out that the available study results may indicate potential for an improved quality of life and a prolongation of survival if an acceptable morbidity and mortality are present.

    With the rising incidence of chronic liver disease caused by viral hepatitis, hepatocellular carcinoma is showing a corresponding rise worldwide. Surgery remains the mainstay of treatment, but patients unfit for surgery or liver transplantation form the bulk of those presenting with this disease. Palliative treatments are being used to treat those and radiological modalities form the mainstay of the treatment. Radiology plays a major role in the diagnosis, treatment and follow-up of hepatocellular carcinoma. Current radiological treatment modalities include percutaneous ethanol ablation, radiofrequency ablation and trans-arterial chemoembolization. This update highlights the recent advancements in the field and compares their relative merits and demerits. (author)

    2008-12-01

    Full Text Available Abstract Background Squamous cells are normally not found inside the breast, so a primary squamous cell carcinoma of the breast is an exceptional phenomenon. There is a possible explanation for these findings. Case presentation A 72-year-old woman presented with a breast abnormality suspected for breast carcinoma. After the operation the pathological examination revealed a primary squamous cell carcinoma of the breast. Conclusion The presentation of squamous cell carcinoma could be similar to that of an adenocarcinoma. However, a squamous cell carcinoma of the breast could also develop from a complicated breast cyst or abscess. Therefore, pathological examination of these apparent benign abnormalities is mandatory.

    Vaginal carcinoma makes up 1%-2% of all gynaecological tumours. Verrucous carcinoma of the vagina is even more rare -only 16 cases are reported in the scientific literature. A case of a complete regression after 60 Gy fractionated radiotherapy by a tumour 12 cm 3 in size is reported. Most authors are of the opinion that radiotherapy causes anaplastic transformation of verrucous carcinoma. The minority view, that anaplastic transformation does not occur, is correct and is supported by our clinical and radiological data. The conflicting literature on vaginal verrucous carcinoma (VVC) is reviewed with reference to verrucous carcinoma at other sites. (Author)

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

    Histologic subclassification of high-grade endometrial carcinomas can sometimes be a diagnostic challenge when based on histomorphology alone. Here we utilized immunohistochemical markers to determine the immunophenotype in histologically ambiguous high-grade endometrial carcinomas that were initially diagnosed as pure or mixed high-grade endometrioid carcinoma, aiming to determine the utility of selected immunohistochemical panel in accurate classification of these distinct tumor types, while correlating these findings with the clinical outcome. A total of 43 high-grade endometrial carcinoma cases initially classified as pure high-grade endometrioid carcinoma (n=32), mixed high-grade endometrioid carcinoma/serous carcinoma (n=9) and mixed high-grade endometrioid carcinoma/clear cell carcinoma (n=2) were retrospectively stained with a panel of immunostains, including antibodies for p53, p16, estrogen receptor, and mammaglobin. Clinical follow-up data were obtained, and stage-to-stage disease outcomes were compared for different tumor types. Based on aberrant staining for p53 and p16, 17/43 (40%) of the high-grade endometrial carcinoma cases initially diagnosed as high-grade endometrioid carcinoma were re-classified as serous carcinoma. All 17 cases showed negative staining for mammaglobin, while estrogen receptor was positive in only 6 (35%) cases. The remaining 26 cases of high-grade endometrioid carcinoma showed wild-type staining for p53 in 25 (96%) cases, patchy staining for p16 in 20 (77%) cases, and were positive for mammaglobin and estrogen receptor in 8 (31%) and 19 (73%) cases, respectively, thus the initial diagnosis of high-grade endometrioid carcinoma was confirmed in these cases. In addition, the patients with re-classified serous carcinoma had advanced clinical stages at diagnosis and poorer overall survival on clinical follow-up compared to that of the remaining 26 high-grade endometrioid carcinoma cases. These results indicate that selected

    2007-06-15

    Approximately 100 cases of collecting duct carcinoma have been reported in the medical literature. We herein report on a case of collecting duct carcinoma of the kidney in a 75-year-old patient. The abdominal sonography depicted a relatively poorly defined 7x6 cm sized, isoechoic mass lesion, as compared to the normal parenchyma, at the left kidney lower pole and the affected kidney showed preservation of the reniform shape. CT revealed a heterogeneous poorly defined low-attenuation mass that was mainly located in the medulla with involvement of the cortex and the lower half of the renal pelvis. Retrograde ureter opyelography showed a filling defect at the lower renal pelvis and severe narrowing of the left proximal ureter. We initially thought this lesion was invasive transitional cell carcinoma. Subsequent surgery confirmed a collecting duct carcinoma

    Objective: To correlate the mammographic findings of mucinous carcinoma with histologic features. Methods: Retrospective analysis of the mammographic and pathologic findings of 37 patients with mucinous carcinomas of the breasts was performed. Results: Mammograms of ten (52.6%) women with mucinous carcinomas showed masses with well-defined, lobu-lated margins correlating well with the pure histologic type. Thirteen (81.3%) mixed type of mucinous carcinomas demonstrated poorly defined or spiculated margins (P<0.05). Most of the pure type carcinomas were hyperdense similar to most of mixed type carcinomas (P<0.05). Of 34 mucinous carcinomas tested, there were 25 ER-positive, 29 PR-positive, 24 C-erbB-2 negative expressions with pure type carcinomas accounting for 78.9%, 89.5% and 78.9%, respectively. Conclusion: The mammographic features of pure type are different from those of mixed type of mucinous breast carcinomas. The most common mammographic appearance of pure mucinous carcinoma is a well-defined mass without calcification whereas the mixed type carcinomas have more aggressive imaging characteristics.

    Objective: To analyze the mammographic features of breast carcinoma and the correlation between the mammographic and pathologic findings. Methods: A prospective study of 397 consecutive mammograms in patients with breast carcinoma, including infiltrating ductal carcinoma (IDC, n=297), ductal carcinoma in situ (DCIS) and DCIS associated with small invasive foci (n=38), mucinous carcinoma (n=21), medullary carcinoma (n=22) and invasive lobular carcinoma (n=19), was performed to determine the correlations between the mammographic and pathologic findings. Results: (1) Microcalcifications appeared in 170 cases (42.8%), a mass in 258 cases (65.0%), and distortion in 33 cases (8.3%), respectively. (2) Microcalcifications were more commonly associated with DCIS and IDC (χ 2 =30.90, P 2 =30.87, P 2 =27.40, P 2 =6.22, P 2 =7.19, P < 0.01). Conclusion: The common features of breast carcinoma in mammography were microcalcifications, microcalcifications with a mass, a mass, and distortion IDC was the commonest in breast carcinoma, and could be considered when mammographic malignant features above mentioned were found except the appearance of microcalcifications alone, which was firstly suggestive of DCIS. A mass also appeared in medullary and mucinous carcinoma, and distortion appeared in invasive lobular carcinoma

    2004-01-01

    Clinical features of multiple squamous cell carcinoma (SCC) cases within the head and neck that were treated in our department during the recent 10 years are discussed. Multiple SCCs arose in 6.6% of the cases with primary SCC; 67% of the cases had two carcinomas, and 33% had more than three carcinomas. The most common site of the multiple SCCs was the oral cavity (54%). The most frequent interval between treatment of previous carcinoma and diagnosis of subsequent carcinoma was simultaneous, but more than 5 years' interval was observed in 36% of the patients. The most common initial treatment of the carcinoma was irradiation, but the ratio of surgery increased for subsequent carcinomas. Prognosis of the patients with more than three carcinomas was not worse than that of patients with two carcinomas. Therefore, early diagnosis of the subsequent carcinomas based on careful long-term observation in the head and neck is necessary for follow-up of the patients with SCC of the head and neck. Treatment strategies considering the treatment of subsequent carcinomas are needed for the patients with primary head and neck SCC. (author)

    The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyma and renal collecting systems are invaded simultaneously. We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renal contour bulging or reinform shape, location of mass center, intact parenchyma overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cell carcinoma, where a and nine of 12 cases of transitional cell carcinoma maintained the reinform appearance. This is significant statiscal difference between the two(P<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(P<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, where as 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(P<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(P<0.05). CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reinform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change

    Full Text Available Simultaneous double cancers in the biliary system are rare. Most are associated with pancreaticobiliary maljunction (PBM. However, it can occur in patients without PBM. Differentiation between these events is important since these two mechanistic origins imply different stages of disease, as well as different subsequent treatments and prognoses. Herein, we report a case of ampullary carcinoma associated with gall bladder carcinoma diagnosed nonoperatively and palliated with biliary metal stenting.

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

    2010-01-01

    Full Text Available Carcinoma of male breast is uncommon as it accounts for 0.7% of total breast cancer. The pathology of male breast cancer is remarkably similar to that of cancers seen in women. The same histological subtypes of invasive cancer are present, although papillary carcinomas (both invasive and in situ are more common and lobular carcinomas are less common. The predominant histological type, in males, as in females, reported in large series has been infiltrating ductal carcinoma with scattered reports of infiltrating lobular carcinoma, all of them of classical type except for a single case of pleomorphic infiltrating lobular carcinoma. Herein, we describe a case of pleomorphic lobular carcinoma occurring in male breast.

    Fibrolamellar carcinoma was first described in 1956. Subsequent large studies failed to identify cases before 1939 (the start of the World War II). This finding, combined with the presence of aryl hydrocarbon receptors on the tumor cells, have suggested that fibrolamellar carcinomas may be caused by environmental exposures that are new since World War II. To investigate this possibility, the surgical pathology files before 1939 were reviewed for hepatocellular carcinomas resected in young individuals. Two cases of fibrolamellar carcinoma were identified, from 1915 to 1924. The diagnosis of fibrolamellar carcinoma was confirmed at the histologic, ultrastructural and proteomic levels. These two fibrolamellar carcinoma cases clarify a key aspect of fibrolamellar carcinoma biology, reducing the likelihood that these tumors result exclusively from post World War II environmental exposures.

    Male breast carcinomas are rare tumours, accounting for less than 1% of all malignancies in men. Intracystic Papillary Carcinoma (IPC) in males is a very rare entity, representing 5-7.5% of all male breast carcinomas. It lacks the classical clinical, radiological and cytological features of malignancy and usually presents as a benign-appearing lump. We report a case of Infiltrating Ductal Carcinoma (IDC) co-existing with intracystic papillary carcinoma in a 53-year-old male who presented with lump in the right breast.

    Full Text Available There seems to be similarities between schizotypal personality and paranormal experiences, in fact, some of the symptoms of PTSD in DSM- match a number of anomalous/paranormal experiences. Positive schizotypy, including magical thinking, hallucinations and other unusual perceptual experiences, has also been associated with paranormal experiences and beliefs. However, paranormal experiences differ from psychotic experiences in nonclinical populations. In order to establish differences between positive and negative symptoms of schizotypy, we compared a group of believers in the paranormal (N= 121 and a sample of undergraduate students (N= 588. The hypothesis that believers would have higher scores in Schizotypy positive symptoms was confirmed. There was a significant difference in positive symptoms of schizotypy among the group of students with and no experiences, although not significant for negative symptoms

    Introduction. Basal cell carcinoma (BCC) is a locally invasive malignant epidermal tumour. Incidence is increasing by 10% per year; incidence of metastases is minimal, but relapses are frequent (40%-50%). The complete excision of the BCC allows reduction of relapse. Materials and Methods. The study cohort consists of 1123 patients underwent surgery for basal cell carcinoma between 1999 and 2009. Patient and tumor characteristics recorded are: age; gender; localization (head and neck, trunk, and upper and lower extremities), tumor size, excisional margins adopted, and relapses. Results. The study considered a group of 1123 patients affected by basal cell carcinoma. Relapses occurred in 30 cases (2,67%), 27 out of 30 relapses occurred in noble areas, where peripheral margin was <3mm. Incompletely excised basal cell carcinoma occurred in 21 patients (1,87%) and were treated with an additional excision. Discussion. Although guidelines indicate 3mm peripheral margin of excision in BCC <2cm, in our experience, a margin of less than 5mm results in a high risk of incomplete excisions

    One hundred twenty-nine patients with far advanced or recurrent gastric carcinoma underwent computed tomography (CT) of the abdomen. There were three histologic types: differentiated (n=41), undifferentiated (n=68), and unclassified (n=20). Eighteen patients who had developed obstructive jaundice were retrospectively studied to elucidate the nature of obstruction with histologic correlation. In differentiated carcinomas tumor tended to grow in an expansive fashion. A fairly large, well-defined lymph adenopathy was observed on CT. The extrahepatic bile duct surrounded by lymph nodes appeared as ''doughnot sign'' in six of eight patients. Undifferentiated gastric carcinoma had tendency to extend infiltratively. Bile duct obstruction was only a part of diffuse spreading. In spite of the presence of obstructive jaundice, no discrete mass was demonstrated around the extrahepatic bile duct on CT. In none of nine patients was present ''doughnot sign''. The significance of lymph node dissection along the extrahepatic bile duct in patients with differentiated gastric carcinoma was emphasized. The region of hepatoduodenal and pancreatico-duodenal lymph nodes should be carefully evaluated in interpretation of abdominal CT. (author)

    Full Text Available Microcystic adnexal carcinoma (MAC is an uncommon skin neoplasm with a predilection location around the lips. It is characterized by cords and nests of neoplastic cells forming ductular or glandular structures that are embedded in dense collagenous stroma. An eighty-seven year old Caucasian female patient presented with a painless, slowly enlarging mass measuring 3.3 x 2.7 x 1.0 cm on the lower lip for approximately 6 months. The patient underwent 2 fine needle aspiration biopsies (FNAs. Smears made from both FNAs demonstrated similar features including low cellular smears, three dimensional cell clusters forming a glandular structure, round to oval cells with high N:C ratio, occasional cytoplasmic lumens, without distinct hyperchromasia, focal inconspicuous nucleoli, smooth regular nuclear membranes, abundant naked nuclei, occasional squamoid cells and focal acellular stromal fragments in the background. The cytologic differential diagnosis included skin adnexal carcinoma and low grade mucoepidermoid carcinoma arising in the minor salivary gland. The mass was subsequently excised. The diagnosis of microcystic adnexal carcinoma was made. We report cytologic features of MAC and also suggest that MAC can possibly be diagnosed by FNA with the appropriate clinical vignette and immunohistochemical profile..

    Most common malignant tumour of the kidney is Renal Cell Carcinoma (RCC) and is known for its unpredictable clinical behaviour. Aetiology and risk factors are not completely understood. Extensive workup is being done in the understanding of the disease, especially to diagnose early and to treat promptly. The objective of this study was to determine the clinical presentation and pathological pattern of RCC. Methods: After approval from ethical committee a retrospective review of records was conducted extending from January 2012 to January 2014 to identify clinical characteristics of renal cell carcinomas. The study included all renal cancer patients presented to Sheikh Zayed Hospital Lahore with in this specified period. The data was retrieved regarding, history, physical examination and necessary investigations such as ultrasonography of abdomen and pelvis and CT scan of abdomen and pelvis. Results: There were total of 50 cases. The male to female ratio was 3:2. Mean age of patients were 52.38 (18-93) years old. Most common clinical presentation was gross haematuria(66%).The mean tumour size was 8.34 (3-24) cm. Tumour histology were clear cell (84%), papillary transitional cell carcinoma (12%) and oncosytoma contributed 4%. Conclusion: We observed that large number of the patients with RCC presented with haematuria and most of them were male. Common pathological type was clear cell carcinoma. (author)

    In the patients with invasive cervical carcinoma, the accurate assessment of parametrial invasion greatly affects the therapeutic choice between surgery and radiation therapy. As a matter of fact, surgery is usually performed only in the patients with carcinoma confined to the cervix, whereas those with parametrial involvement, or more advanced stages, are treated with radiation therapy. This prospective study was aimed at investigating the comparative adequecy of CT and MR imaging in assessing parametrial status in the patients with invasive cervical cancer. Twenty-one consecutive patients, with histologic diagnosis of cervical carcinoma, were investigated. All of them were clinically considered as having invasive cervical cancer (FIGO stage IB-IIB) and subsequently underwent surgery. In all cases, detailed histology of the parametrium was obtained. Pathological data were compared with CT and MR findings in all cases. As for assessing parametrial involvement by cancer, CT had 62% accuracy, 63% sensitivity, and 60% specificity, versus MR imaging 81% accuracy, 69% sensitivity, and 80% specificify. Therefore, MR imaging appears to be superior to CT in assessing the parametrial status of patients with invasive cervical carcinoma; the method yields valuable information for treatment planning

    To determine the optimal pulse sequence for detection and differential diagnosis of small hepatocellular carcinomas and cavernous hemangiomas less than 5 cm in diameter, the authors have analyzed spin-echo (SE) images of 15 small hepatocellular carcinomas and 31 small cavernous hemangiomas obtained at 2.0 T. Pulse sequences used included repetition times (TRs) of 500 and 2,000 msec and echo times (TEs) of 30,60,90,120,150, and 180 msec. Mean tumor-liver contrast-to-noise ratios on the SE 2,000/60 (TR msec/TE msec) sequence were 23.90 ± 16.33 and 62.10 ± 25.94 for small hepatocellular carcinomas and hemangiomas, respectively, and were significantly greater than for all other pulse sequences. Mean tumor-liver signal intensity ratios on the SE 2,000/150 sequence were 2.34 ± 1.72 and 6.04 ± 2.72 for small hepatocellular carcinomas and hemangiomas, respectively, and were significantly greater than for all other pulse sequences in hemangiomas

  18. Laryngeal adenoid cystic carcinoma: case report

    Directory of Open Access Journals (Sweden)

    André Del Negro

    Full Text Available CONTEXT: Adenoid cystic carcinomas are malignant tumors that occur in both the major and the minor salivary glands. A laryngeal location is rare because of the paucity of accessory salivary glands in this area. Adenoid cystic carcinomas account for less than 1% of all malignant tumors in the larynx, and only about 120 cases have been reported in the literature. These tumors have a slight female predisposition, and their peak incidence is in the fifth and sixth decades of life. In this article, we describe a case of laryngeal adenoid cystic carcinoma and discuss its clinical characteristics and treatment. CASE REPORT: We report on a case of laryngeal adenoid cystic carcinoma in a 55 year-old female patient who presented with dyspnea and hoarseness. Features of the diagnostic and therapeutic evaluation are described and the clinical management of such cases is outlined. The clinical course, definitive treatment strategy and surgical procedure, and also adjuvant treatment with irradiation are discussed. Although the tumor is radiosensitive, it is not radiocurable.

  19. Vulvar basal cell carcinoma, a rare location

    Full Text Available Basal Cell Carcinoma is the most common human malignant neoplasm. Vulvar basal cell carcinoma is rare, accounting for less than 5% of all vulvar neoplasms. Vulvar basal cell carcinomas are usually diagnosed late because they are often asymptomatic and tend to grow at slow rates. They are usually diagnosed late because they are often asymptomatic. However, these tumours may appear in areas which are normally covered with ultraviolet light. We present the case of a 60 years old woman diagnosed with invasive breast cancer for which she underwent surgery followed by chemotherapy and radiotherapy. The patient presented to our department with an ulcerated vulvar lesion. On inspection, the tumour measured 3/2 cm and was located on the left labium majus. The biopsy confirmed the diagnosis of vulvar basal cell carcinoma and a wide local excision was performed with no relapse at one year. In conclusion, early detection of BCC’s is critical to allow complete surgical cure so any abnormality on the vulva should be biopsied. A wide safety margin of 1cm should be achieved when resecting the tumour and the physician should keep in mind that the BCC’s of the vulva has a high recurrence rate. Previous chemotherapy is not associated with this type of non-melanoma skin cancer.

    2005-01-01

    Full Text Available Carcinoma cuniculatum, a low grade squamous carcinoma of plantar skin was first described in 1954. Even after 50 years, biopsy errors are common with delay in diagnosis. Clinico-morphologica1 features in 12 patients of carcinoma cuniculatum, in a period of three and a half years are studied. The aim is to draw attention to the sites of occurrence of this tumor other than the sole and to have better understanding of the diagnostic difficulties. The sites of occurrence of these tumors according to frequency were foot followed by flank, leg, face and palm. The tumors presented with ulcerated, fungating masses with fine papillary architecture. Microscopic examination of the tumors revealed bulbous acanthosis, parakeratosis and a well defined lower border, circumscribed by chronic inflammatory cells. No lymph node metastasis were recorded in any of the cases. Wide local excision with at least five mm free surgical margin was the treatment of choice. A transmetatarsal and above wrist amputation was required in two patients. Carcinoma cuniculatum should always be suspected in a nonhealing ulcer or verrucous growth of long standing duration. Superficial and small biopsies are unsatisfactory. Benign appearance on histopathology of this tumor needs to be interpreted in proper clinical settings.

    A total of 47 patients with a diagnosis of nasopharyngeal carcinoma was treated in Department of Therapeutic Radiology, Seoul National University Hospital during last 4 years. Of the 47 patients, 23(49%) had undifferentiated carcinoma, 20(43%) had squamous cell carcinoma, while 4(8%) had lymphoepithelioma. Most of the patients(71%) has Stage IV disease, cervical lymph node metastases were found in 36(77%) and distant metastasis was found in 1 at the time of diagnosis. Complete response rate after radiotherapy for 47 patients of nasopharyngeal carcinoma was 85.1%. The overall actuarial 3 year survival rates was 0.718 and the disease free actuarial 3 year survival rates was 0.468. Nodal involvement and symptom duration were statistically significant influencing factors for actuarial survival rate. Treatment failures were found in 20 patients (42.6%), local recurrence only in 6(30%), local and neck recurrence in 3(15%), local recurrence with metastasis in 4(20%) and distant metastasis only in 7(35%). Local failures were more frequent in the patients with cranial nerve symptoms (P=0.032). Distant metastases were more frequent with T4 lesions (P=0.047), and with nodal involvement (P<0.01). Retreatment after the tumor recurrence was chemotherapy and/or radiotherapy, two patients retreated for local recurrence were alive without evidence of disease for more than 19 and 44 months after retreatment

    Importance High-grade serous carcinoma (HGSC) is the most prevalent and lethal form of ovarian cancer. HGSCs frequently arise in the distal fallopian tubes rather than the ovary, developing from small precursor lesions called serous tubal intraepithelial carcinomas (TICs or more specifically STICs). While STICs have been reported to harbor TP53 mutations, detailed molecular characterizations of these lesions are lacking. Observations We performed targeted next generation sequencing (NGS) on formalin-fixed, paraffin- embedded tissue from four women, two with HGSC and two with uterine endometrioid carcinoma (UEC) who were diagnosed with synchronous STICs. We detected concordant mutations in both HGSCs with synchronous STICs, including TP53 mutations as well as assumed germline BRCA1/2 alterations, confirming a clonal relationship between these lesions. NGS confirmed the presence of a STIC clonally unrelated to one case of UEC. NGS of the other tubal lesion diagnosed as a STIC unexpectedly supported the lesion as a micrometastasis from the associated UEC. Conclusions and Relevance We demonstrate that targeted NGS can identify genetic lesions in minute lesions such as TICs, and confirm TP53 mutations as early driving events for HGSC. NGS also demonstrated unexpected relationships between presumed STICs and synchronous carcinomas, suggesting potential diagnostic and translational research applications. PMID:26181193

All patients had undergone diagnostic sonomammography. The imaging findings were identified by experienced breast imagers. Final surgical pathology results were used as the reference standard.Results: Thirty-two women ranging in age from 42 to 63 years old (mean age, 53 years, All had biopsy-proven invasive lobular carcinomas. Common features on mammogram included dense mass followed by architectural distortion; three cases showed breast asymmetry and one case was reported as normal. On ultrasound, common features included solid mass with spiculated margins, posterior shadowing, and perpendicular to the skin.Conclusion: Although no specific features could be linked to invasive lobular carcinoma, care should be directed to subtle signs such as architectural distortion and breast asymmetry in order not to miss any lesions. The combination of mammographic and sonographic helps to decrease the relatively high false negative diagnosis of this type of breast cancer.Keywords: mammography, ultrasound, cancer, breast

    2002-01-01

    To present a case of papillary carcinoma in an autonomously hyperfunctioning thyroid nodule. We chronicle the clinical and laboratory findings in a patient with a painless neck mass, with a particular focus on the pathologic findings after surgical removal of the right thyroid lobe. A 39-year-old woman had an enlarging nodule of the right thyroid lobe. Results of thyroid function tests suggested subclinical hyperthyroidism. Two months later, the patient complained of increasing swelling in the neck (but still had no symptoms suggestive of hyperthyroidism). Thus, resection of the right thyroid lobe was performed. Pathologic analysis disclosed low-grade papillary thyroid carcinoma within the nodule, with a small rim of compressed inactive-appearing thyroid tissue surrounding the nodule. Subsequently, she underwent total thyroidectomy and follow-up care for thyroid carcinoma. Although solitary hyperfunctioning nodules of the thyroid gland are usually considered benign, the current case suggests that the diagnosis of autonomous thyroid nodules does not preclude thyroid carcinoma in a functioning nodule.

    Merkel cell carcinoma is a rare skin tumor of neural crest origin and is part of the amine precursor uptake and decarboxylase system. It typically occurs on the face of elderly people. Distant metastasis is almost uniformly fatal. Choroidal metastasis, to our knowledge, has not been described. We report a patient with Merkel cell carcinoma who had a synchronous solid choroidal tumor and a biopsy-proven brain metastasis. Our 56-year-old patient presented with a rapidly growing, violaceous preauricular skin tumor. Computed tomography of the head disclosed incidental brain and choroidal tumors. Light and electron microscopy of biopsy specimens of both the skin and the brain lesions showed Merkel cell carcinoma. Ophthalmoscopy, fluorescein angiography, and A and B echography revealed a solid choroidal mass. The brain and skin tumors responded well to irradiation. A radioactive episcleral plaque was applied subsequently to the choroidal tumor. All tumors regressed, and the patient was doing well 28 months later. To our knowledge this is the first case of presumed choroidal metastasis of Merkel cell carcinoma

    Most prognostic studies in differentiated carcinoma have included a high number of papillary carcinomas and few follicular carcinomas, and not all of their conclusions therefore apply to the latter. To analyze the prognostic factors of follicular thyroid carcinoma. Patients with histological diagnosis of follicular carcinoma who had undergone potentially curative surgery, had no disseminated disease at diagnosis, and had been followed up for at least 5 years. Tumor recurrence was defined as: 1) tumor lesions with cytological analysis suggesting malignancy and/or 2) patients with total thyroidectomy with thyroglobulin levels >2 ng/mL. Clinical, therapeutic, and histological parameters were analyzed to assess prognostic factors. Recurrence was found in 25 (38%) of the 66 study patients during a follow-up period of 99 ± 38 months. Most patients with recurrence (n=20) had increased Tg levels without anatomical location, and were initially treated with radioactive I131. In the remaining 5 cases, surgical excision of the lesion was performed, and three patients required surgery during the follow-up period. Two patients died due to the disease (3%), and two other patients (3%) currently have distant metastases. Mean disease-free interval was 154 ± 14 months, and rates of disease-free patients at 5, 10, 15, and 20 years were 71, 58, 58, and 58% respectively. Clinical factors influencing recurrence included 1) age (p=0.0035); 2) sex (p=0.0114); and 3) cervical pain (p=0.0026). Histological/surgical factors associated with recurrence included 1) infiltration into neighboring structures (p=0.0000); 2) type of carcinoma (p=0.0000); 3) size (p=0.0162); 4) vascular invasion (p=0.0085); and 5) adenopathies (p=0.046). In the multivariate study, cervical pain (p=0.018) and extrathyroid invasion (p=0.045) continued to be significant factors. In follicular carcinoma, rates of disease-free patients are 71% at 5 years and 58% at 10 years, and the main predictive factors are presence

    The current work was conducted to study the disease status and treatment results of patients with differentiated thyroid carcinoma referred for radioactive iodine therapy. Retrospective review of 78 patients with differentiated thyroid carcinoma referred for radioiodine therapy in the Nuclear Medicine Unit, King Abdulaziz Hospital and Oncology Center, Jeddah, Kingdom of Saudi Arabia. Analysis of the clinicopathologic characteristics, age correlation to different risk factors, treatment protocol and results were performed. Seventy seven percent were female and the female to male ratio was 3.5:1. The age of patients ranged between 13-63 years with a median age of 36 years. Cervical lymph node involvement was detected in 22 patients (25%). Papillary carcinoma was encountered in 78 patients (90%) and follicular carcinoma in 9 patients (10%). Analysis of the clinicopathologic characteristics showed no statistically significant difference between patients in the different age groups except for extrathyroid extension and lymph node involvement. Patients older than 45 years had a statistically significant lower incidence of nodal involvement and higher incidence of extra thyroid extension (P<0.02). In the current study we used a high dose method (Radioiodine-131 dose 75-100mCi) for thyroid remnant ablation after thyroidectomy (total or near total) in 67 patients. An Iodine 131 dose of 150 mCi was used in 12 patients with radioiodine-avid cervical lymph nodes and in 3 patients with gross residual tumor. In 4 patients with distant metastases an Iodine 131 dose of 200 mCi was used. For the whole study group the 5 year overall survival and disease-free survival was 96% and 88%. The current study, as with many other retrospective studies, concluded that despite the fact that differentiated thyroid carcinoma is among the most curable cancers, some patients are still at high risk for recurrent disease and associated mortality.

    Full Text Available Background: Carcinoma of breast has become the major public health problem among females in developing as well as developed countries. InNepal it comprises 6% of total cancers cases and often diagnosed at advanced stage. Surgical removal or modified radical mastectomy (MRM is the most commonly used tools for disease management. The objective of this study is to identify the clinical, macroscopic and microscopic features of MRM specimens.Materials and methods: This prospective cross-sectional study was carried out at Department of Pathology, Bhaktapur Cancer Hospital, Bhaktapur, Nepal. Macroscopic and microscopic examination provided the tumor size, stage, grade, lymph node status, lympho-vascular invasion and perineural invasion. Data were collected and analyzed using SPSS 16.Results: The study comprised 112 breast cancer patients of which 109 (97.3% were females and 3 (2.7% were males. Invasive ductal carcinoma no specific type was the most common type of breast carcinoma. (84 cases accounting 75% of total cases. Carcinoma with medullary features was second most common (6 cases comprising 5.4% cases followed by lobular, papillary, apocrine, mucinious and NST mixed types. Grade II tumors were most frequent grade observed in 76.79% cases followed by Grade I (12.50% and Grade III (10.71%.Conclusion: As a conclusion invasive ductal carcinoma was the most common histological type breast cancer and the tumors were found at T2 and N3 stage i.e maximum at grade II. Our study provides prognostic significance of histo-pathological information in breast cancer management.

    The incidence of thyroid carcinoma in hyperthyroidism varies considerably from as low as 0.3% to as high as 16.6% with a higher rate in toxic nodular goiters. Occult thyroid carcinoma (thyroid carcinoma was 5.6% (23 cases). In detail, a neoplasm occurred in 5 cases of Graves' disease (specific incidence: 3.8%), in 13 cases of toxic nodular goiter (12.5%) and in 5 cases of hyperfunctioning adenomas (2.8%). 19 cancers were papillary (12 in toxic nodular goiter, 3 in Graves' disease, 4 in hyperfunctioning adenomas), three were follicular (1 in Graves' disease, 1 in toxic nodular goiter, 1 in hyperfunctioning adenomas) and 1 medullary in Graves' disease. A papillary carcinoma was diagnosed preoperatively on fine needle aspiration with ultrasonography in only two patients with Graves' disease and confirmed by postoperative histological examination on permanent section. We do not believe in the frozen-section examination intraoperatively because it's not diagnostical for follicular lesions and evaluates rarely capsular invasion. Twenty patients received total thyroidectomy and four of them also lymphoadenectomy. Three patients received emithyroidectomy: in two cases for occult papillary carcinoma and in the last case for local cancer invasion (T4N0M0). Twenty patients are alive and with no evidence of cancer recurrence. Mean follow-up is 59.6 months. Our retrospective study shows a progressive increase of the incidence of coexisting thyroid malignancy and hyperthyroidism especially in toxic nodular goiter, probably related to extended surgical indications. Our findings do confirm that, even in the presence of hyperthyroidism, all thyroid nodules require careful diagnostics for exclusion of malignancy.

    From January 1967 through November 1991, a total of 135 patients with carcinoma of the major salivary glands (parotid: 95; submandibular: 39, sublingual: 1) were treated at our department. 40 patients had adenocarcinoma, 29 adenoid cystic carcinoma, 24 mucoepidermoid carcinoma and 16 squamous cell carcinoma. 100 patients were irradiated postoperatively and the remaining 35 were treated with radiation alone. Total radiation doses delivered were 50 Gy for the postoperative group and 50 to 66 Gy for the group receiving only radiation using a [sup 60]Co single portal with or without wedged paired or single electron portal boost. Actuarial five-year survivals after radiation therapy were 55% for the postoperative group and 26% for radiation only group (p=0.0004). The local control rates for the postoperative group were 83% for adenocarcinoma, 81% for adenoid cystic carcinoma, 83% for mucoepidermoid carcinoma and 62% for squamous cell carcinoma. Corresponding figures for the radiation only group were 40% for adenocarcinoma, 38% for adenoid cystic carcinoma and 33% for mucoepidermoid carcinoma. Conventional irradiation techniques continue to play an important role because they offer superior local control for postoperative patients with carcinoma of the major salivary glands. However, the local control rates for the radiation only group were only 30 to 40%, so that new irradiation modalities such as provided by a high LET machine are needed for these patients. (orig.)

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

    The association of sarcomatoid carcinoma (SC) with small cell carcinoma (SCC) has not been systematically studied. We identified 39 consult cases between 2001 and 2016 with available slides for review in 28 cases. There were 19 men and 9 women (mean age: 78 years [51-89]). In 26 (92.8%) cases, the sarcomatoid component had nonspecific malignant spindle cells, 4 (14%) chondrosarcoma, 2 (7%) myxoid sarcomatous, 1 (3.5%) osteosarcoma, and 1 (3.5%) rhabdomyosarcoma. The predominant component was SCC in 11 (39%) cases, urothelial carcinoma in 6 (21%), sarcomatoid in 3 (10%), and equal sarcomatoid and SCC in 8 (29%). There were 3 morphological groups: group 1 (18/28 [64%]) showed a gradual transition from SCC to other components; group 2 (5/28 [18%]) had an abrupt transition from SCC to other components; and in group 3 (5/28 [18%]), the SCC was separate from other components. In group 1, 12 (66%) cases of SCC showed a gradual transition to sarcomatoid areas; 3 (17%) to urothelial carcinoma; and 3 (17%) to multiple components including squamous cell carcinoma, urothelial carcinoma, and sarcomatoid. Mortality did not differ based on pathological groups. The 36-month actuarial risk of death was 64.3%. The multitude of different components in these tumors is further evidence of the remarkable ability of carcinoma of the bladder to show divergent differentiation with, in some cases, gradual transition between SCC and other elements including sarcomatoid. Greater recognition of this entity with chemotherapy targeted to the various histological elements may have important therapeutic implications. Copyright © 2017 Elsevier Inc. All rights reserved.

    The expression of E74-like factor 5 (ELF5) in epithelial ovarian carcinoma tissues and its effects on biological behavior in ovarian carcinoma cells were assessed in search for a new approach for gene treatment of epithelial ovarian carcinoma. RT-PCR technology was applied to detect the expression of ELF5 mRNA in epithelial ovarian carcinoma (n=49), borderline ovarian epithelial tumor (n=19), benign ovarian epithelial tumor (n=31) and normal ovarian tissues (n=40). Then, we transfected recombinant plasmid pcDNA3.1‑ELF5+EGFP into human ovarian carcinoma SKOV3 cells (recombinant plasmid group) in vitro and screened out stably transfected cells to conduct multiplication culture. Western blot analysis was performed to detect the expression of ELF5 protein in the different groups. Flow cytometry was employed to detect cell apoptosis and cycles. ELF5 mRNA in epithelial ovarian carcinoma and borderline ovarian epithelial tumor tissues were significantly lower (Pepithelial tumor and normal ovarian tissues. ELF5 protein expression in the cells of recombinant plasmid group was significantly higher compared with empty plasmid and blank control groups. The capacity of cell reproductive recombinant plasmid group at each time point decreased (P<0.05). Flow cytometry detection showed that 67.03% of cells in recombinant plasmid group was blocked in G0/G1 phase (P<0.05), compared with empty plasmid group (37.17%) and blank control group (38.24%). Apoptotic rate of recombinant plasmid group was significantly lower (31.4±1.9%; P<0.05), compared with that of empty plasmid group (9.1±2.2%) and blank control group (8.7±1.5%), and the differences were statistically significant. In conclusion, ELF5 interfered with cell cycle of human ovarian carcinoma SKOV3 cells and promoted apoptosis of human ovarian carcinoma SKOV3 cells inhibiting their growth and invasive capacity; and thus providing a new approach to gene treatment of ovarian carcinoma.

    1977-01-01

    A heterologous antiserum for human cervical squamous cell carcinoma was prepared and specificity determined by Ouchterlony immunodiffusion and immunofluorescence studies. With this antiserum, a tumor antigen was purified from human cervical squamous cell carcinoma tissue. The specificities of the antigen and the antiserum were then re-examined by a radioimmunoassay method using 125 I-labeled purified antigen. Although normal cervical tissue extract showed a moderate cross-reactivity in the radioimmunoassay, the circulating antigen activity could not be detected in normal women or in several patients with other carcinomas, whereas 27 of 35 patients with cervical squamous cell carcinoma showed detectable serum antigen activity. All patients with advanced stages of cervical squamous cell carcinoma showed detectable antigen levels. These results indicate that there is a quantitative abnormality, at least, of this tumor antigen in patients with cervical squamous cell carcinoma and that the radioimmunoassay for the antigen is a potentially useful tool in clinical care

    Thyroid carcinomas are rare during childhood and adolescence. They have increased recently probably due to a higher frequency radiation over the head, neck and mediastinum. The papillary carcinoma is the most common and true follicular carcinoma is far less common. Follicular thyroid carcinoma is associated with endemic goiter, genetic disorders, and increased TSH levels. Its morphological characteristics are peculiar and have been recently redefined, thus helping the diagnosis. A minimally invasive follicular thyroid carcinoma in 13 years old girl is described, presenting a hypocaptant thyroid nodule in the left lobe lower pole. The fine needle aspiration biopsy revealed a follicular cell lesion suspicious of malignancy. Thyroid lobectomy was performed reporting minimally invasive follicular carcinoma.

    2013-02-01

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

    Objective: The main aim of this barium enema study was to evaluate its role in patients suspected to have rectal pathologies with complaints of change in bowel habit, anorexia/weight loss, bleeding per rectum and acute/sub-acute colonic obstruction. Results: barium enema study as screening test for colo-rectal carcinoma was undertaken. Contrast outlined the colonic growth in 35 cases, out of which the cases of carcinoma colon were 24 including 13 patients suffering from carcinoma rectum. The percentage of carcinoma colon to total colonic growth was 68% while, carcinoma rectum to total carcinoma colon was 54%. Conclusion: On the basis of these investigations, it is concluded that patient's compliance is important factor in the early detection of colonic neoplasia. Though results of colonoscopy are more reliable but in practice, barium enema (double contrast) is performed initially to outline the lesion and then colonoscopy for biopsy purpose. (author)

    2011-01-01

    Hepatocellular carcinoma is now a major public health concern. In intermediate stages (one third of hepatocellular carcinoma patients), chemo-embolization is the standard of care despite a poor tolerance and a moderate efficacy. Moreover, despite recent improvements, this technique seems in a dead end. Radio-embolization could be an excellent tool for such patients. Currently 131 I-Lipiodol, 188 Re-Lipiodol, 90 Y-glass or resin microspheres are available. More recent and promising data come from microspheres, but phase II and III studies are needed before drawing any conclusion. In the future, the combination of radio-embolization with systemic chemotherapy or targeted agents (particularly anti-angiogenic drugs) seems very promising. (authors)

    2012-01-31

    Squamous cell carcinoma ofthe anal canal represents 1.5% of all malignancies affectingthe gastrointestinal tract. Over the past 20 years dramatic changes have been seen in both the epidemiological distribution of the disease and in the therapeutic modalities utilised to manage it. CLINICAL MANAGEMENT: Historically abdominoperineal resection had been the treatment of choice with local resection reserved for early stage disease. Work by Nigro et al. has revolutionised how we currently manage carcinoma of the anal canal, demonstrating combined modality chemoradiotherapy as an appropriate alternative to surgical resection with the benefit of preserving sphincter function. Surgery is then reserved for recurrent disease with salvage abdominoperineal resection. This article reviews current literature and highlights the changing therapeutic modalities with selected clinical cases

    2014-12-01

    Full Text Available Urothelial carcinoma with abundant myxoid stroma is a newly-described and extremely rare entity. Since only very few cases have been reported, there is no consensus on its nomenclature. Microscopic examination revealed invasive urothelial carcinoma with widespread low-grade noninvasive areas. There were focal invasive areas in the neighborhood of the renal parenchyma. Malignant urothelial tumor/cell groups localized in the stroma had abundant myxoid/mucinous background in the invasive areas. The cytoplasm of the tumoral cells was more eosinophilic in these areas and the cells formed small groups and cords. Histochemically, PAS and Alcian Blue were positive in the cytoplasm of the tumoral cells and in the stroma while negative in the non-mucinous areas. Immunohistochemically, the tumoral cells of the mucinous invasive areas diffusely expressed MUC1 and MUC2. We discuss the origin of the mucinous/myxoid stroma, the tumor’s nature and its nomenclature with histochemical and immunohistochemical features.

    The squamocellular carcinoma is a malignant neoplasm commonest in the buccal cavity. The more frequently involved anatomical sites are the lower lip, the tongue's lateral edges and the mouth floor. Its etiology is multifactor although it is closely related to smoking and alcoholism. Clinical picture is generally characterized by the presence of different types of white, erythematous, between erythematous and white plaques, ulcers with raised edges and exophytic masses. Treatment includes surgical removal, radiotherapy, chemotherapy or both. In present paper the case of a man aged 70 presenting with buccal squamous carcinoma describing the clinical, and the histopathologic findings and its corresponding treatment. The early and appropriate diagnosis allowed the cure of this case. (author)

    1985-01-01

    Five patients with early esophageal carcinoma were treated by 6-12 Gy of intracavitary irradiation following 50-60 Gy of external irradiation as a boost therapy. Surgery was not performed in these cases. None of the patients had local recurrence after radiation therapy, as demonstrated by esophagography and endoscopy. Three patients have been alive for 1-3 years 10 months. Esophageal ulceration induced by intracavitary irradiation has occurred in three of the five patients; however, intracavitary irradiation is still a beneficial treatment because of its efficacy in controlling local lesions and because radiation ulceration can eventually be cured. Intracavitary irradiation is recommended to follow external irradiation as a boost therapy for the treatment of early esophageal carcinoma

    The aim of the present study was to gain more insight into the natural history of endometrial carcinoma, to evaluate prognostic factors and to assess the various treatment methods and the results. Using the data of the Norwegian Radium Hospital, where treatment of gynecological cancer is centralized to a great extent, a large series of patients with long term follow-up, covering all clinical stages and recurrences of endometrial carcinoma, could be evaluated. This resulted in five articles. These articles, together with a study from the University Hospital in Groningen are presented and discussed, and recommendations for treatment are given. The relevant treatments assessed are postoperative external irradiation, preoperative uterine radium packing, preoperative low dose external irradiation and radiotherapy alone. (Auth.)

    Itai, Y.; Araki, T.; Tasaka, A.; Maruyama, M.

    1982-01-01

    Thirteen patients with resectable pancreatic carcinoma were examined by computed tomography (CT). Nine had a mass, 2 had dilatation of the main pancreatic duct, 1 appeared to have ductal dilatation, and 1 had no sign of abnormality. Resectable carcinoma was diagnosed retrospectively in 8 cases, based on the following criteria: a mass with a distinct contour, frequently containing a tiny or irregular low-density area and accompanied by dilatation of the caudal portion of the main pancreatic duct without involvement of the large vessels, liver, or lymph nodes. Including unresectable cancer, chronic pancreatitis, and obstructive jaundice from causes other than cancer, the false-positive rate was less than 6%. However, a small cancer without change in pancreatic contour is difficult to detect with CT

    Full Text Available Carcinoma gall bladder is a very aggressive disease with poor outcomes. Despite achievements in the field of advanced imaging techniques, there is a very high mortality rate of the disease Cancer is the second most common disease in India responsible for maximum mortality with about 0.3 million deaths per year. The magnitude of cancer problem in the Indian Sub-continent (sheer numbers is increasing due to poor to moderate living standards and inadequate medical facilities. Women are more commonly affected than men. The peak incidence occurs in people in their 60s, but the disease age range is from 29 to 90 years of age and there is great geographic and ethnic variation. Carcinoma gall bladder, a disease of old age, is now found in the younger age group and presents with greater ferocity.

    1985-01-01

    The immunoscintigraphic results in 12 human pancreatic carcinomas established on nude mice (Nu-Nu-Balb-C) are reported. 131 I-labeled monoclonal antibodies against CA 19-9, CEA and CA 125 were used. The result show that pancreatic carcinomas are detectable with the antibodies applied here. The quality of the scintigraphic detection depends, among other factors, on the antibody affinity to the tumor, the localization and the size of the tumor. Preliminary results of the studies on radioimmunotherapy of pancreatic cancer with 131 I-anti-CA 19-9 indicate that effective absorbed doses in the tumor may be achieved via intravenous application only in cases with a rather high expression of the tumor antigen. But direct instillation into the tumor enables therapeutic radiation doses to the tumor even with moderate affinity and a low whole-body burden. (orig./MG) [de

    Among 910 survivors of childhood cancer, four developed infiltrating carcinoma of the breast and another had noninfiltrating breast tumor. Expected frequency was 0.3 cases of breast cancer in the series. The affected women developed breast carcinoma at ages 20, 25 and 38 years, and the men at ages 38 and 39 years, respectively. Each patient had received orthovoltage chest irradiation for treatment of Wilms' tumor or bone sarcoma between seven and 34 years previously, and estimated radiation dose to the breast exceeded 300 rad in each instance. Four patients also received diverse forms of chemotherapy. Survivors of childhood cancer have increased risk of developing breast cancer and should undergo periodic screening, particularly after breast tissue had been irradiated. Individualized radiotherapy planning can help exclude the breasts from treatment fields for some thoracic neoplasms

    Scanning of the stomach after administration of {sup 131}I and {sup 99m}Tc is presented. Experiments on 20 dogs were performed and 105 patients were examined. The studies with {sup 131}I are only mentioned briefly as they have been summarized in a previous publication and we have concentrated on our experience with {sup 99m}Tc and on stomach carcinoma. The turnover of the nuclide in blood, urine, gastric juice and gastric mucosa was tested: in-vivo and post-operative scannings were performed. The scans are classified in four groups. Carcinoma of the stomach results in space-occupying lesions or foggy scans. A correlation of 85 - 90% between scan results and clinical findings is noted. A special group of 10 volunteers was examined to establish the possibility of a screening examination for the detection of stomach cancer using the technique presented. (author)

    Malignant tumors of the larynx are extremely rare in children and adolescents. Adenoid cystic carcinoma accounts for less than 1% of all malignant tumors in the larynx. We presented a 16-year-old girl with subglottic adenoid cystic carcinoma, whose symptoms of prolonged and exacerbating dyspnea had been attributed to asthma at another medical center. Indirect flexible and rigid laryngoscopy revealed a smooth mass in the subglottic region occupying 80% of the airway passage. The lesion was also confirmed by both CT and MRI. There was no lymphadenopathy in the neck. The patient was successfully treated by surgery and postoperative radiotherapy. Pathological staging was T4N0M0 according to the AJCC, 2003. During six years of follow-up, there was no evidence for local recurrence or regional and distant metastasis.

    Full Text Available The aim of this study is to evaluate the incidence and prevalence of malignant kidney tumors, to contribute to identifying factors which the diagnosis of renal cell carcinomas. Through this study, we understand that kidney disease over the years had higher incidence rates, especially in adults in the sixth decade of life. The renal cell carcinoma (RCC is the third most common malignancy of the genitourinary tract, affecting 2% to 3% of the population. There are numerous ways of diagnosis; however, the most important are ultrasonography, magnetic resonance imaging and computed tomography. In general most of the patients affected by the CCR, have a good prognosis when diagnosed early and subjected to an effective treatment. This study conducted a literature review about the CCR, through this it was possible to understand the development needs of the imaging methods used for precise diagnosis and classification of RCC through the TNM system.

    1988-01-01

    To analyze the atypical radiographic spectrum of ductal carcinoma in situ (DCIS), the authors retrospectively reviewed the mammograms of 190 women who had biopsy-proved DCIS at Malmo General Hospital between January 1976 and March 1988. Of these, 117 (61.6%) showed clustered microcalcifications as the major abnormality, a finding often associated with DCIS. The remaining 73 women (38.4%) had either negative mammograms (30 women) or radiographic findings not usually associated with DCIS (43 women), including circumscribed masses (15 women) and focal conglomerates of prominent ducts and nodules (12 cases). Since treatment of DCIS may cure the disease, the radiologist should learn to recognize the more unusual mammographic manifestations of intraductal carcinoma

    Three hundred and four patients with squamous cell carcinomas of the oral cavity were treated at the Finsen Institute in cooperation with the ENT-surgical departments between 1978 and 1982. The primary treatment consisted of radiotherapy alone in 74%, surgery alone in 4%, and a combination of radiotherapy and surgery in 15% of the patients. 2% received other treatment (cryotherapy), 5% did not complete the planned radiotherapy, and 1% were not treated at all. Of 203 patients with tumour remnant or first recurrence, 45% were operated, 2% received radiotherapy, and 2% combined treatment. This treatment strategy made 38% of the patients free of disease in the follow-up period (3 1/2 to 8 years) or until the patients died from other causes. Fifty-nine percent of the patients died from their oral carcinomas. Tumour size (T), lymph node status (N), and tumour stage were as expected important prognostic factors. (orig.)

    Manoela Marchezan Piva

    Full Text Available ABSTRACT: Mammary gland neoplasms in cattle are rarely observed in the field veterinary diagnostics routine. Therefore, the objective of this study is to report a metastatic mammary carcinoma in a fourteen-year-old Holstein cow in the state of Santa Catarina, Brazil. The animal was diagnosed by the field veterinarian with clinical mastitis that was unresponsive to treatment, and was euthanized due to the poor prognosis. At the necropsy, multiple yellow, firm, and sometimes friable nodules, ranging from 0.1 to 20cm were observed in all mammary glands, lymph nodes, kidneys, spleen, liver, pancreas, mediastinal lymph nodes, heart, and lungs. The final diagnosis of mammary carcinoma was established through the association of clinical, necropsy, histopathological, and immunohistochemical findings. Differential diagnoses included diseases such as bovine tuberculosis and chronic fungal or bacterial mastitis.

    To determine the frequency and profile of carcinoma in multi-nodular goiter and solitary thyroid nodule. Study Design: Case series. Place and Duration of Study: Surgical Unit-I, Ward-3 of Jinnah Postgraduate Medical Centre, Karachi, from January 1999 to January 2009. Methodology: Cases with solitary thyroid nodules and multi-nodular goiter were included. Patients under 12 years of age, cystic benign lesion in solitary thyroid nodules or those multi-nodular goiters which were not causing pressure symptoms, cosmetic problems or sign of malignancy were excluded. In solitary thyroid nodule, hemithyroidectomy was done and if histopathology examination revealed carcinoma thyroid then completion thyroidectomy was done. In multi-nodular goiter sub-total thyroidectomy done. Results were described as frequency percentages and mean. Results: Out of 397 patients of multi-nodular goiter only one patient was found to be papillary carcinoma (0.25%). In 220 patients of solitary thyroid nodules, 93 patients were diagnosed as carcinoma of thyroid (42.27%). Others diagnosed in solitary thyroid nodule were thyroid adenoma, colloid goiter, thyroiditis and multi-nodular goiter. The frequency of papillary carcinoma in 65.95% occurring females of 12-30 years of age and being multifocal in 6.45%, follicular carcinoma in 23.40%, medullary carcinoma in 7.44%, anaplastic carcinoma in 2.12% and lymphoma in 1.01%. Female were predominantly involved and papillary carcinoma was common in 12-30 years of age (71.63%) and follicular was common in 30-40 years of age (68.18%). 6.45% of papillary carcinoma was found to be multifocal in nature. Conclusion: Frequency of carcinoma of thyroid is very high in solitary thyroid nodule (42.27%), but markedly low in multi nodular goiter. Papillary carcinoma is the most common variety, most of in younger female. (author)

    Measurement of s-Tg is of limited value in the diagnosis of primary thyroid tumor but is very useful in post-operative management of differentiated thyroid carcinoma. The sensitivity and the specificity of Tg determination is comparable to that obtained with whole body scan WBS, however, both are complimentary. In our experience, the accuracy of s-Tg determination whether on or off thyroxin medication does not differ significantly

    Renal cell carcinoma (RCC) is a malignant lethal tumour with high potential of metastasis. However, metastasis from RCC to the skin is much less common. It is virtually a sign of poor prognosis. We represent a 42 years old man with bilateral RCC of clear cell type followed by metastasis to the scalp one month later. In this case the relatively young age of the patient, bilaterality of RCC and occurance of skin metastasis in the absence of recurrent kidney tumour are interesting.

    Dose rate calculations, combined with observations of tissue dimensions, lead to the conclusion that radon and its daughters in the airspace produce a greater dose rate in the mastoid air cell epithelium, the tissue at risk for mastoid carcinomas in radium cases, than do radium and its daughters in bone. As the conclusion is based on limited tissue data, assumed values for the radioactivity in bone and airspace, and a number of important assumptions, it must be considered tentative

    Skin squamous cell carcinomas (SCCs) are arguably the second most common carcinoma of the skin and are responsible for the majority of non-melanoma skin cancer deaths. Gynecologist treated a Caucasian 56-years old female patient for genital wart with podophyllotoxin cream. She did not achieve complete response and therefore she has interrupted the therapy and the collaboration with the gynecologist. At the time of evaluation the lesion had a size of man's palm in anogenital region and showed characteristic features of neoplasm. The regional lymph nodes have produced infiltrated painful bubo. PCR analysis for HPV proved negative. Histopathology revealed well-differentiated squamous cell keratinizing carcinoma from the tumor as well as from the regional lymph node packet. Staging computed tomography scans proved negative and pelvis scans disclosed regional lymphadenopathy underlying the tumor. Palliative radiation therapy (by linear accelerator) was administered for the oversized tumor to the total TD 50.0Gy. The patient died 6 months after diagnostic assessment from cardio-respiratory failure. Staging computed tomography before her death did not disclose distinct metastases in her inner organs. Well-differentiated squamous cell keratinizing carcinoma could be growing endophytically affecting the underlying adipose tissue and musculature, with spreading into the regional lymph nodes. The rate of metastases into inner organs seems to vary according to the aggressiveness and metastatic behavior of each SCC. The case report calls for attention to the importance of collaboration among various specialists assisting in the diagnosis and management of skin neoplasm (Fig. 5, Ref. 12).

    Ductal carcinoma in situ (DCIS) is a noninvasive malignant breast disease traditionally described as a precursor lesion to invasive breast cancer. With screening mammography, DCIS now accounts for approximately 20% of newly diagnosed cancer cases. DCIS is not well understood because of its heterogeneous nature. Studies have aimed to assess prognostic factors to characterize its risk of invasive potential; however, there still remains a lack of uniformity in workup and treatment. We summarize current knowledge of DCIS and the ongoing controversies.

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

    Objective: To investigate the CT characteristics of anaplastic thyroid carcinoma and evaluate the diagnostic value of CT in this disease. Methods: The CT findings of 10 patients with pathologically proved anaplastic thyroid carcinoma were retrospectively reviewed. The patients included 7 females and 3 males. Their age ranged from 25.0 to 78 years with median of 61 years. Multi-slices plain and post contrast CT scans were performed in all patients. Results: Unilateral thyroid was involved in 6 patients. Unilateral thyroid and thyroid isthmus were both involved in 2 patients due to big size. Bilateral thyroid were involved in 2 patients. The maximum diameter of anaplastic thyroid carcinoma ranged from 2.9-12.8 cm with mean of (4.5 ± 1.4) cm. All lesions demonstrated unclear margins and envelope invasion. The densities of all lesions were heterogeneous and obvious necrosis areas were noted on precontrast images. Seven lesions showed varied calcifications, and coarse granular calcifications were found in 5 lesions among them. All lesions showed remarkable heterogenous enhancement on post-contrast CT. The CT value of solid portion of the tumor increased 40 HU after contrast media administration. The ratios of CT value which comparing of the tumor with contralateral sternocleidomastoid muscle were 0.69-0.82 (0.76 ± 0.18) and 1.25-1.41 (1.33 ± 0.28) on pre and post CT, respectively. Enlarged cervical lymph nodes were found in 6 cases (60.0%). It showed obvious homogeneous enhancement or irregular ring-like enhancement on post-contrast images and dot calcifications were seen in 1 case. Conclusions: Relative larger single thyroid masses with coarse granular calcifications, necrosis,envelope invasion, remarkable heterogeneous enhancing and enlarged lymph nodes on CT are suggestive of anaplastic thyroid carcinoma.

    Thirty eight women with recurrent breast carcinoma involving chest wall and/or regional lymph nodes after surgery with or without systemic therapy were treated with radiation between 1979 and 1986. Among them, 5 patients were excluded from analysis because of incomplete treatment. The median follow up of survivors was 30 months (ranged 1-79 months). Fifteen (45%) patients had their disease confined to the chest wall and eighteen patients had lymph node involvement as some of their locoregional recurrent disease. Within 36 months after the initial treatment, 87% of recurrences manifested themselves. All patients had radiotherapy to at least the site of involvement. In 8 patients, recurrent tumors were treated with complete excision followed by radiation. Of the remaining 25 patients, 18(72%) had complete response (CR) following radiotherapy. The actuarial 3-year survival of all patients following locoregional recurrence was 50%. Three year survival was 24% in those 25 patients who had recurrences within 24 months of the initial treatment. For those 8 patients whose recurrences occurred after more than 24 month disease free interval, the 3-year survival was 100%. For those patients with recurrences confined to chest wall alone, 3-year survival was 57%. The patients who had lymph node involvement as part of their locoregional recurrences had a 43% 3-year survival. The majority of them developed distant metastases. Those patients who had a CR showed 63% 3-year survival. On the other hand, 1 year survival was only 33% for those patients who had a less than CR. Three patients developed carcinoma of the contralateral breast following radiotherapy. Three year survival following locoregional recurrence was 40% for patients whose initial treatment for their primary breast carcinoma was surgery and adjuvant systemic therapy. For those patients whose primary breast carcinoma was treated by surgery alone, the 3-year survival following locoregional recurrence was 71%. In

    A young woman with a thyroid papillary carcinoma behaving as an autonomously hyperfunctioning nodule is described. Only 17 similar patients have been seen in the past 25 years. It is emphasized that hyperthyroidism does not exclude malignant disease in hot nodules. This possibility suggests that all thyroid nodules, either cold or hot, require careful management. Therefore, in 'at risk' cases, surgery could be the most useful treatment. (orig.)

Radiotherapy is the primary treatment modality. The role of systemic therapy has become more prominent. Based on multiple phase III studies and meta-analyses, concurrent cisplatin-based chemoradiotherapy is the current standard of care for locally advanced disease (American Joint Committee on Cancer manual [7th edition] stages II–IVb. The reported failure-free survival rates from phase II trials are encouraging for induction + concurrent chemoradiotherapy. Data from ongoing phase III trials comparing induction + concurrent chemoradiotherapy with concurrent chemoradiotherapy will validate the results of these phase II studies. Intensity-modulated radiotherapy techniques are recommended if the resources are available. Locoregional control exceeding 90% and reduced xerostomia-related toxicities can now be achieved using intensity-modulated radiotherapy, although distant control remains the most pressing research problem. The promising results of targeted therapy and Epstein–Barr virus-specific immunotherapy from early clinical trials should be validated in phase III clinical trials. New technology, more effective and less toxic chemotherapy regimens, and targeted therapy offer new opportunities for treating nasopharyngeal carcinoma.Keywords: nasopharyngeal carcinoma, intensity-modulated radiotherapy, chemoradiotherapy, molecular targeted agents, immunotherapy, prognostic markers

    Eight patients with epidermoid carcinoma of the penis received methotrexate, five with high-dose methotrexate, 250--1500 mg/m2 with citrovorum rescue Q 2--4 weeks, and three with low-dose methotrexate, 0.5--3.0 mg/kg weekly. Three (38%) patients achieved a complete or partial remission which persisted for 11, 3 and 2 months, respectively. Methotrexate appears to be an active agent in the treatment of advanced penile cancer.

    The specimens obtained from 32 patients with carcinoma of the esophagus were histologically studied to evaluate the radiation effect on the primary lesions and regional lymph node metastases. The patients consist of 21 preoperatively irradiated cases and 11 autopsy cases. Radiation effect was divided into three grades according to Ohboshi-Shimosato's classification. A total dose of 20 to 55 Gy was given to preoperatively irradiated cases and that of 38 to 80 Gy to autopsy cases. The microscopic examination of the primary lesions revealed marked effect in 11 cases, moderate effect in 12 cases and mild or none effect in 9 cases. Radiation effect on carcinoma of the esophagus seemed to be related to the length of the primary lesion (p<0.001); the tumor of 6 cm or less showed marked effect in 9 out of 12 cases (75%), and that of more than 6 cm in only 1 of 19 cases (5%). As for the radiological type of the primaty lesions, superficial or tumorous type seemed to be more effective than serrated or spiral type. As for the histological subtypes, poorly defferentiated squamous cell carcinoma seemed to be more radiosensitive than moderately or well differentiated squamous cell carcinoma. Radiation effect on lymph node metastases within radiation field was correlated to that of the primary lesions. Our results suggest that for radical treatment of esophageal cancer a patient with the tumor length of 6 cm or less should be chosen, although radiological type and/or tumor grade can't also be ignored as a predictor.

    Having found raised serum calcitonin concentrations in 94% of patients with hepatocellular carcinoma when using a dextran-coated-charcoal radio-immunoassay, we have now repeated the study, using a double-antibody radio-immunoassay, in 102 further patients with hepatocellular carcinoma and 35 matched controls. Serum immunoreactive calcitonin concentrations (iCT) in the controls ranged from 10 to 310 pg/ml (mean 154,6 pg/ml). Values in the tumour patients ranged from 10 to 1,650 pg/ml (mean 302,6 pg/ml). The mean figures were significantly higher in the tumour patients (P smaller than 0,001), 35.5% of them having values above 310 pg/ml. In 65 of the patients serum iCT concentrations were also determined by dextran-coated-charcoal radio-immunoassay. Values ranged from 10 to 10780 pg/ml (mean 2,179 pg/ml). If 1,000 pg/ml is taken as the upper limit of normal, 69% of the patients had raised iCT concentrations. There was a good correlation (r=0,67; P smaller than 0,001) between serum iCT values measured with both methods in 50 patients. If measured by the double-antibody radio-immunoassay method, the serum calcitonin value is not useful as a marker for hepatocellular carcinoma.

    To evaluate radiological findings in patients submitted to surgical treatment for medullary breast cancer at Instituto Nacional de Cancer (INCa), Rio de Janeiro, RJ, Brazil, correlating them with histological results. A retrospective descriptive study was developed with patients submitted to surgery at INCa, in the period from January 1997 to December 2006, for identifying the presence of medullary breast carcinoma and analyzing radiological findings. Among 21,287 patients diagnosed with carcinoma, 76 (0.357%) had typical medullary breast carcinoma. The age range of these patients was 32-81 years (mean = 59.1 years). Mammography demonstrated lesions in 19 of these patients, 17 (89.5%) of them with masses, and 2 with focal asymmetry. Among the patients with masses, 15 (88.1%) presented with high density and 2 (11.9%) with isodensity. Twelve patients presented sonographic findings, 11 (91.6%) of them with hypoechoic masses, and one with an anechoic mass with areas of cystic degeneration. Nodular mass was the predominant radiological finding (89.5%), 88.1% of them corresponding to masses with high density and circumscribed margins. Despite the radiological characteristics of benignity, a solid, fast growing, highly dense mass with circumscribed margins should be further investigated to confirm the diagnosis. (author)

    1987-01-01

    The risk of thyroid carcinoma induction, due to external or internal exposure of the thyroid, is described and quantified. A modified absolute risk model is used. The assessment is based on a risk coefficient of 2.5 induced cases per million persons per cGy per year of risk, derived from US-investigations in persons who had received external radiation therapy during childhood for treatment of benign diseases. This value is considered to be suitable for a dose range of 0.06-15 Gy. Modifying factors are given for age at exposure, gender and relative effectiveness of various radiation sources. The minimum induction period is taken to be 5 years; the remaining life expectancy minus minimum induction period is considered as the number of years at risk. For external exposure of the general public, a calculated incidence for lethal thyroid carcinoma of 7.5 cases per million persons per cGy thyroid dose for the total life time may be derived from the average life expectancy, the age distribution of the population and a mortality of radiation induced thyroid carcinoma of 10%. This figure is in good agreement with earlier estimates. (orig./ECB) [de

    Histological diagnosis of laryngeal epithelial abnormalities may range from mucosal aberration, without risk of progressing into invasive neoplasm, to in situ or invasive carcinoma. Precise identification of epithelial abnormalities of laryngeal mucosa requires biopsy and microscopic evaluation. Random biopsies are frequently inadequate, since they are not representative for the entire lesion. Excisional Biopsy, allowing removal of lesion together with a rim of healthy tissue is ideal for both diagnosis and treatment. If completely removed, the cancer should not require further treatment; if the margins are not free of disease, re-excision or radiotherapy is considered as alternative options. Laser excision represents an extension of the clinical application of endoscopy, allowing the laryngologist to perform an accurate and bloodless surgery. Endoscopic laser treatment for selected glottic SCC (squamous cell carcinoma) has been shown to provide an excellent alternative to radiotherapy or open neck surgery in terms of cure rate and functional results. Preliminary results are presented with the purpose of stressing the role of EB with CO2 laser in diagnosis and treatment of selected glottic carcinoma. (author). 16 refs

    To determine the computed tomographic (CT) characteristics of nonfunctioning islet cell carcinoma of the pancreas, the CT scans of 27 patients with that disease were reviewed. The pancreatic tumor was identified as a mass in 26 patients (96%) Of the 25 tumors evaluated with contrast enhancement, 20 became partially diffusely hyperdense relative to nearby normal pancreatic tissue. Hepatic metastases were identified in 15 patients (56%), regional lymphadenopathy in 10 (37%), atrophy of the gland proximal to the tumor in six (22%), dilatation of the biliary ducts in five (19%), and dilatation of the pancreatic duct in four (15%). The CT appearances of the nonfunctioning islet cell tumors were compared with those of 100 ordinary (ductal) pancreatic adenocarcinomas. Although the two types of tumors were sometimes indistinguishable, features found to be more characteristic of islet cell carcinoma included a pancreatic mass of unusually large size, calcification within the tumor, and contrast enhancement of either the primary tumor or hepatic metastases. Involvement of the celiac axis or proximal superior mesenteric artery was limited to ductal carcinoma.

    Purpose: To evaluate the impact of both adjuvant and definitive radiotherapy on local control of adrenocortical carcinoma. Methods and Materials: Outcomes were analyzed from 58 patients with 64 instances of treatment for adrenocortical carcinoma at the University of Michigan's Multidisciplinary Adrenal Cancer Clinic. Thirty-seven of these instances were for primary disease, whereas the remaining 27 were for recurrent disease. Thirty-eight of the treatment regimens involved surgery alone, 10 surgery plus adjuvant radiotherapy, and 16 definitive radiotherapy for unresectable disease. The effects of patient, tumor, and treatment factors were modeled simultaneously using multiple variable Cox proportional hazards regression for associations with local recurrence, distant recurrence, and overall survival. Results: Local failure occurred in 16 of the 38 instances that involved surgery alone, in 2 of the 10 that consisted of surgery plus adjuvant radiotherapy, and in 1 instance of definitive radiotherapy. Lack of radiotherapy use was associated with 4.7 times the risk of local failure compared with treatment regimens that involved radiotherapy (95% confidence interval, 1.2-19.0; p = 0.030). Conclusions: Radiotherapy seems to significantly lower the risk of local recurrence/progression in patients with adrenocortical carcinoma. Adjuvant radiotherapy should be strongly considered after surgical resection.

    Seventy patients of oral carcinoma, including lip and tongue cancer, were treated at University of Tsukuba Hospital from March 1988 to March 1998. Treatment for each patient was determined according to TNM classification (UICC, 1987). Eight cases of non-squamous cell carcinoma, which were insensitive to radiation or chemotherapy, were surgically treated. Out of 70 cases, sixty-two were pathologically categorized as squamous cell carcinoma (SCC). For SCC cases of stage I or II, full-dose irradiation, including brachytherapy as well as conventional irradiation, was fundamentally the treatment of choice, but in six cases surgical treatment was performed after irradiation of 50 Gy in order to assure curability. In cases of stage III or IV, the treatment of choice was a combination of the surgery and radiotherapy. Fifteen cases, however, were treated only by conventional radiotherapy, brachytherapy (RALS) and/or chemotherapy, because of the patient's refusal to surgery, local or systemic condition, his or her age, and so on. Our treatment plans have consequently resulted in the overall 5-year survival rate of 75.2% for oral SCC. (author)

    Purpose A retrospective analysis of risk factors for late neurological toxicity after nasopharyngeal carcinoma radiotherapy. Patients and methods Between 1993 and 2004, 239 patients with non metastatic nasopharyngeal carcinoma were treated by radiotherapy associated or not to chemotherapy. Radiotherapy was delivered with two modalities: hyperfractionated for 82 patients and conventional fractionation for 157 patients. We evaluated the impact of tumour stage, age, gender, radiotherapy schedule and chemotherapy on neurological toxicity. Results After a mean follow-up of 107 months (35-176 months), 21 patients (8.8%) developed neurological complications, such as temporal necrosis in nine cases, brain stem necrosis in five cases, optics nerve atrophy in two cases and myelitis in one case. Five- and ten-year free of toxicity survival was 95 and 84% respectively. Young patients had greater risk of temporal necrosis, and hyperfractionated radiotherapy was associated with a significantly higher risk of neurological complications (14.6% vs 5.7%, p = 0.02). On multivariate analysis, hyperfractionation and age were insignificant. Conclusion Late neurological toxicity after radiotherapy for nasopharyngeal carcinoma was rare. Younger age and hyperfractionation were considered as risk factors of neurological toxicity in our study

    Full Text Available OBJECTIVE: To assess the occurrence of upper urinary tract urothelial tumors (UUTT in Brazil. MATERIALS AND METHODS: We performed a clinical and histopathologic study of 33 patients who were diagnosed with a malignant neoplasm in the renal pelvis or ureter in the period of 1994 to 2004, in a single institution. RESULTS: Among the patients with upper urinary tract carcinoma, 70% were males and 30% females, with mean age of 65 ± 16 years (ranging from 31 to 91 years. Nineteen patients presented renal pelvis tumor (58%, 9 ureteral tumor (27% and 5 synchronic pelvic and ureteral tumors (15%. Renal pelvis tumors represented 2.8% of all the urothelial neoplasms, and 11.4% of all renal neoplasms treated in the same period. Ureteral tumors represented 1.6% of all the urothelial malignancies surgically managed in these 11 years. Tobacco smoking was the most common risk factor, and analgesic abuse was not reported by those patients. Most carcinomas were high-grade and muscle-invasive. Mean time to diagnosis was 7 months, being hematuria the most common symptom. CONCLUSIONS: A high association was also found between UUTT and bladder urothelial carcinoma. UUTT were mostly seen in men in their seventies and related to a high overall and cancer-related mortality rate. The overall disease-specific survival was 40%, much lower than found in most of the reported series.

    Full Text Available Abstract Background Leptomeningeal carcinomatosis occurs in patients with cancer at the rate of approximately 5%; it develops particularly in patients with breast cancer, lung cancer, melanoma, leukemia, or malignant lymphoma. We describe a rare case of leptomeningeal carcinomatosis in which spinal intradural squamous cell carcinoma with no lesions in the cerebral meninges and leptomeninx, was the primary lesion. Methods A 64-year-old man complained of sacral pain. Although the patient was treated with analgesics, epidural block and nerve root block, sacral pain persisted. Since acute urinary retention occurred, he was operated on. The patient was diagnosed as having an intradural squamous cell carcinoma of unknown origin. Results Since the patient presented with a slightly decreased level of consciousness 2 months after surgery, he was subjected to MRI scanning of the brain and spinal cord, which revealed disseminated lesions in the medulla oblongata. The patient died of pneumonia and sepsis caused by methicillin-resistant Staphylococcus aureus 5 months after surgery. Conclusion We report the first case of a patient with intradural squamous cell carcinoma with unknown origin that developed independently in the sacrum.

    Follicular carcinomas are the second most common form of thyroid cancer, accounting for 10 to 20% of all thyroid cancers. Follicular carcinomas have a propensity to metastasize via the bloodstream, spreading to bone, lungs, liver, and elsewhere. We described the case of a 48-year-old woman who presented with swelling of the left pre auricular area, which was a consequence of a metastatic follicular carcinoma of the masticator space. Plain films showed ill defined erosive bony changes from the left condylar head to the mandibular notch. Contrast-enhanced CT images showed a well circumscribed round mass with well enhancement within left masticator space. On MR images, the mass was heterogenously hyperintense to the muscle on T2-weighted images and isointense or hyperintense to the muscle on T1-weighted images, and showed good enhancement on contrast-enhanced T1-weighted images. Upon microscopic examination, the metastatic mass was found to be composed of fairly uniform cells forming small follicles containing colloid, showing capsular and vascular invasion.

    Orbital metastasis of hepatocellular carcinoma is exceedingly rare and caries a grave prognosis. Three cases of metastatic orbital hepatocellular carcinoma in which the primary tumor was initially unknown and the diagnostic challenges encountered are presented. With hepatocellular carcinoma, open biopsy and palliative tumor debulking has an increased bleeding risk due to the highly vascular nature of the tumor and coagulopathy associated with chronic liver disease. As an alternative, fine needle aspiration biopsy should be considered for hepatocellular carcinoma with a readily accessible mass and the availability of an experienced cytopathologist.

The aim of the study is to evaluate the histopathological diagnosis of cancer cervix and to determine the incidence of the various types of cancerous lesions. MATERIALS AND METHODS It was a prospective study in the Department of Pathology, Andhra Medical College/King George Hospital over a period of one year. 152 women with carcinoma cervix were included in the study. RESULTS 152 cases of carcinoma of cervix were in the age group of 28-76 years. The mean age of the patients with carcinoma cervix is 52.97. Histologically, Large Cell Non-Keratinising Squamous Cell Carcinoma (LCNKSCC constituted the majority of carcinoma cervix cases, i.e. 134 cases (88.15%. 3 (1.97% cases of adenocarcinoma of cervix were diagnosed in the present study. Majority of cases of carcinoma cervix were in stage III, i.e. 64 cases (64%, followed by stage II in 24 cases (24% and stage IB in 8 cases (8%. CONCLUSION Large Cell Non-Keratinising Squamous Cell Carcinoma (LCNKSCC is the most common histological type of carcinoma cervix. A relatively large proportion of patients presented in stages IIIA and IIIB. There is a need to reinforce the early detection of carcinoma cervix and its precursor lesions, especially in developing countries.

    Mortality rate of hepatocellular carcinoma is high. The majority of the patients are diagnosed in advanced stage and lose surgical opportunities. Many studies have reported transcatheter arterial chemoembolization (TACE) is an effective treatment for unresectable hepatocellular carcinoma, and recommended TACE as a standard treatment for hepatocellular carcinoma of Barcelona Clinical Liver Cancer staging (BCLC staging) B. However, TACE can hardly fully embolize tumor blood supply, TACE postoperative hemodynamics and angiogenesis can induce tumor recurrence and metastasis. This paper reviewed characteristics of vascular changes, mechanisms, diagnosis and treatment methods, new progress in the field of hepatocellular carcinoma after TACE. (authors)

    Invasive lobular carcinomas are the second most common type (5% to 15%) of invasive breast carcinomas. The most frequent sites of breast cancer metastasis are the local and distant lymph nodes, brain, lung, liver, and bones; metastasis to the gastrointestinal system, especially to the stomach, is rare. When a mass is detected in an unusual place in a patient with invasive lobular carcinoma, it should be kept in mind that such a mass may be either a second primary carcinoma or the metastasis o...

    Full Text Available We report a rare case of synchronous presentation of nasopharyngeal and renal cell carcinomas in a-50-year old male patient with long standing smoking history. The patient was initially presented with a diagnosis of nasopharyngeal carcinoma. During staging process, the abdominal computed tomography detected a right renal solid mass, 6.5 cm in diameter, originating from posterior portion of the right renal cortex. Right radical nephrectomy was performed and pathological examination revealed renal cell carcinoma. Smoking was thought to be a risk factor for both cancers. Systemic evaluation of kidney should not be discarded in patients diagnosed with nasopharyngeal carcinoma living in western countries with a smoking history.

    An editorial is presented which discusses the treatment of carcinoma of the anal canal. Following the initial report of the successful preoperative use of combined chemotherapy and radiation by Nigro in 1974, several centers have confirmed the effectiveness of such combinations either as preoperative or as definitive treatment of anal carcinomas, and many patients are now being referred for radiation therapy. The article by Cantril in this issue describe the successful treatment of anal carcinomas by radiation alone, and raises the important issue of whether radiation plus chemotherapy is more effective treatment than radiation alone for squamous or cloacogenic carcinomas arising in the anal canal or perianal area. Several studies are cited

    Cutaneous neuroendocrine (Merkel cell) carcinoma most often arises de novo in the background of a clonally integrated virus, the Merkel cell polyomavirus, and is notable for positive expression of retinoblastoma 1 (RB1) protein and low expression of p53 compared with the rare Merkel cell polyomavirus-negative Merkel cell carcinomas. Combined squamous and Merkel cell tumors are consistently negative for Merkel cell polyomavirus. Little is known about their immunophenotypic or molecular profile. Herein, we studied 10 combined cutaneous squamous cell and neuroendocrine carcinomas for immunohistochemical expression of p53, retinoblastoma 1 protein, neurofilament, p63, and cytokeratin 20 (CK20). We compared mutation profiles of five combined Merkel cell carcinomas and seven 'pure' Merkel cell carcinomas using targeted next-generation sequencing. Combined tumors were from the head, trunk, and leg of Caucasian males and one female aged 52-89. All cases were highly p53- and p63-positive and neurofilament-negative in the squamous component, whereas RB1-negative in both components. Eight out of 10 were p53-positive, 3/10 p63-positive, and 3/10 focally neurofilament-positive in the neuroendocrine component. Six out of 10 were CK20-positive in any part. By next-generation sequencing, combined tumors were highly mutated, with an average of 48 mutations per megabase compared with pure tumors, which showed 1.25 mutations per megabase. RB1 and p53 mutations were identified in all five combined tumors. Combined tumors represent an immunophenotypically and genetically distinct variant of primary cutaneous neuroendocrine carcinomas, notable for a highly mutated genetic profile, significant p53 expression and/or mutation, absent RB1 expression in the context of increased RB1 mutation, and minimal neurofilament expression.

    The management of in situ lesions ductal carcinoma in situ (DCIS) and lobular carcinoma in situ (LCIS) continues to evolve. These diagnoses now comprise a large burden of mammographically diagnosed cancers, and with a global trend towards more population-based screening, the incidence of these lesions will continue to rise. Because outcomes following treatment for DCIS and LCIS are excellent, there is emerging controversy about what extent of treatment is optimal for both diseases. Here we review the current approaches to the diagnosis and treatment of both DCIS and LCIS. In addition, we will consider potential directions for future management of these lesions.

    Purpose: To assess the role of radiotherapy alone or in combination with surgery in the treatment of patients with malignant minor salivary gland carcinomas. Methods and Materials: Between October 1964 and November 1992, 95 patients with minor salivary gland carcinomas of the head and neck received radiotherapy with curative intent. Eighty-seven patients were previously untreated, and 8 were treated for postsurgical recurrence. Fifty-one patients were treated with radiotherapy alone, and 44 were treated by surgical resection plus radiotherapy. Patients were staged according to the 1983 American Joint Committee on Cancer (AJCC) staging criteria for squamous cell carcinomas. Results: The 20-year actuarial rate of local control was 57% with no significant difference according to histologic type. When tumor stage was taken into consideration, there were no significant differences in local control according to tumor site. The 12-year actuarial probability of distant metastases was 40% (19% as the only site of failure). In multivariate analyses, local control was significantly affected only by tumor stage and treatment type (combined therapy better than radiotherapy alone); tumor stage was a significant predictor of cause-specific survival and freedom from relapse. Freedom-from-relapse rates were higher for patients who received combined treatment (p = 0.068). Conclusions: Treatment of minor salivary gland carcinomas is usually by combined surgery and radiotherapy, but there are situations where surgery alone or radiotherapy alone may be used. The ability to control these tumors with radiotherapy alone is not widely recognized. In the present series, the tumor was locally controlled in 20 patients with previously untreated primary lesions after radiotherapy alone (2.5 to 21 years) and in 4 other patients who were treated by radiotherapy alone for postsurgical recurrent tumor (3.5 to 14 years after radiotherapy). Contrary to the widely held belief that local recurrence

    Full text: Analysis of data of the oncological outpatient clinics of the Republic of Uzbekistan confirms our data obtained in the Institute of Endocrinology showing growth in iodine deficiency disorders. In the Republic of Uzbekistan, during period from 1983 to 1999, 6374 people were detected to have thyroid carcinoma. If in 1989, 1.95 cases of thyroid tumor accounted for 100000 population, in 1999 this index reached to 2.39. Moreover, among metropolitan population this was 4.6 cases in 1989, and 8.0 in 1999. Of the 4280 patients operated for different thyroid pathologies from 1989 to 1999 in the Institute of Endocrinology, 335 (7.9%) were diagnosed to have thyroid carcinoma. Clinical presentation was: multinodular goiter in 50.8%, nodular goiter in 37.3% and autoimmune thyroiditis in 4.2% of cases. The average age of patients operated for thyroid carcinoma was 42.8 years in 1989 and 32 years in 1999. Treatment of patients with thyroid carcinoma should be near total thyroidectomy with selective lymphadenectomy independent of morphologic form of the tumor. Our data showed that only surgical method of treatment was used in 7.4% of patients but in combination of radioiodine in 81.9% of patients. Radioiodine was used to destroy remnant thyroid tissue and iodine concentrating metastases. 131I treatment for destruction of thyroid remnants after measured from the front, back and lateral positions in radical operation was given by fractionation method with average total activity being 25 mCi to 75 mCi. Metastases into neck lymph nodes and mediastinum were treated with radioactivity ranging from 50 mCi to 100 mCi. Of the total patients of differentiated thyroid cancer treated from 1995-1999, 148 were alive on 01.01.2003 with five-year survival rate of 91.4%. Our results highlight that combined surgical and radioiodine treatment of thyroid carcinoma helps in preventing recurrence, metastasis and results in increasing the lifespan of patients. (author)

    In order to determine the differential points between them, we analyzed the CT findings of invasive thymoma and thymic carcinoma. We retrospectively reviewed the CT scans of 14 patients with invasive thymoma and 15 with thymic carcinoma, confirmed by surgery(n=3D19) or percutaneous needle aspiration(n=3D10) between 1988 and 1996. CT findings were evaluated in each group for intrathoracic spread(posterior, direct posterior, and anterolateral), obliteration of the fat plane between the mass and vascular structures, vessel encasement, invasion of adjacent mediastinal structures, pleural implants, mediastinal nodes and distant metastasis. Direct posterior spread was more common in thymic carcinoma than invasive thymoma;it was seen in one case (7%) of invasive thymoma and 12(80%) of thymic carcinoma(p=3D0.00). Posterior spread was seen in six cases (43%) of in vasive thymoma and nine (60%) of thymic carcinoma. Anterolateral spread was seen only in two cases (13%) of thymic carcinoma. Obliteration of the fat plane was seen in nine cases (64%) of invasive thymoma and 14 (93%) of thymic carcinoma, while vessel encasement was seen in two cases (14%) of invasive thymoma and 13(87%) of thymic carcinoma(p=3D0.00). Invasion of adjacent structures was seen in two cases (14%) of invasive thymoma and eight (53%) of thymic carcinoma. Pleural implants were more common in invasive thymoma than thymic carcinoma, being seen in six cases (43%) of the former and one (7%) of the latter(p=3D0.04). Mediastinal lymphadenopathy was seen in three cases (21%) of invasive thymoma and ten (67%) of thymic carcinoma. Distant metastases were observed only in six cases (40%) of thymic carcinoma(p=3D0.02). Although differentiation between invasive thymoma and thymic carcinoma is difficult on the basis of CT findings, there are certain differential points. Thymic carcinomas showed a higher rate of direct posterior intrathoracic spread, vessel encasement, mediastinal nodes and distant metastases than

    The incidence of thyroid carcinoma is increasing worldwide. Graves' disease is the most common hyperthyroid disease. Studies have suggested an increased risk of thyroid malignancy in Graves' disease: there has not yet been a meta-analysis to allow quantitative comparison. The purpose of this study was to determine the risk of thyroid carcinoma in Graves' disease, and to gather information on the histological subtypes of carcinoma and the co-existence of thyroid nodules. Several databases and article reference lists were searched. Inclusion criteria included appropriate diagnostic criteria for thyroid conditions and a diagnoses of carcinoma based on histology. 33 studies were selected, all reporting on surgically-resected specimens. The event rate of thyroid carcinoma in Graves' disease was 0.07 (95% CI 0.04 to 0.12). There was no data to allow comparison with patients without hyperthyroid diseases. There was no increase in the odds of developing carcinoma in Graves' disease compared to toxic multinodular goitre and toxic uninodular goitre. 88% of thyroid carcinomas in Graves' disease were papillary, with solitary papillary micro-carcinoma (diameter 10 mm or less) comprising 23% of all detected thyroid carcinomas. Patients with Graves' disease and co-existing thyroid nodules were almost 5 times more likely to be diagnosed with thyroid carcinoma than those without nodules. Thyroid malignancy in Graves' disease requiring surgical treatment should be considered as likely as in other hyperthyroid diseases needing surgical treatment. Clinicians should consider screening selected patients with Graves' disease for nodules whilst being aware of potentially over-diagnosing papillary micro-carcinoma. Crown Copyright © 2015.

    Full Text Available Background. Renal cell carcinoma (RCC has unpredictable and diverse behavior. The classic triad of hematuria, loin pain, and abdominal mass is uncommon. At time of diagnosis, 25%–30% of patients are found to have metastases. Bones, lungs, liver, and brain are the frequent sites of metastases. RCC with metastasis to the head and neck region and thyroid gland is the rarest manifestation and anaplastic carcinoma behaving metastatic thyroid mass is an extremely rare presentation of RCC. Case Presentation. A 56-year-old Saudi man with past history of right radical nephrectomy 5 years back presented with 3 months history of rapid increasing neck mass with dysphagia, presenting like anaplastic thyroid carcinoma. Tru-cut biopsy turned out to be metastatic renal cell carcinoma. Patient was treated with radiation therapy 30 Gy in 10 fractions to mass. Patient died 4 months after the discovery of anaplastic thyroid looking metastasis. Conclusion. Rapidly progressing thyroid metastases secondary to RCC are rare and found often unresectable which are not amenable to surgery. Palliative radiotherapy can be considered for such patients.

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

    To determine if proton magnetic resonance spectroscopy ( 1 H MRS) of thyroid carcinoma is feasible and to determine if 1 H MRS spectra of malignant tumors differ from that of normal thyroid tissue. We performed 1 H MRS at 1.5 T at echo-times (TE) 136 and 272 ms to examine eight patients with thyroid cancer (primary tumour or nodal metastasis) larger than 1 cm 3 in size and five volunteers with normal thyroids. Spectra acquired from six primary tumors (three anaplastic carcinomas, two papillary carcinomas and one follicular carcinoma) and two nodes (two papillary carcinoma metastases) were analyzed in the time-domain using a non-linear least squares fitting algorithm with incorporation of prior knowledge. Choline (3.2 ppm) was identified in all solid carcinomas with a mean choline/creatine of 4.3 at TE 136 ms and 5.4 at TE 272 ms. Ratios for malignant tumors at TE 136 ms ranged from 1.6 in well differentiated follicular carcinoma to 9.4 in anaplastic carcinoma. No choline was detected in normal thyroid tissues. Our results showed that 1 H MRS is a feasible technique for the evaluation of malignant thyroid tumors larger than 1 cm 3 and that proton spectra of malignant tumors differ from that of normal thyroid tissue
