1/63. Clinicopathological report: mucinous carcinoma of the eyelid.BACKGROUND: Mucinous carcinoma of the skin is a rare tumour that may involve the peri-ocular region. methods/RESULTS: A case report is presented of a 73-year-old woman with a right upper lid tumour, initially diagnosed as a basal cell carcinoma. Excisional biopsy of the residual tumour revealed mucinous carcinoma. Re-examination of the original pathology proved to be mucinous carcinoma, originating in the eyelid skin. Further treatment involved wide local resection and reconstruction. Systemic investigations were undertaken to exclude the possibility of metastatic mucinous carcinoma. CONCLUSION: This case is presented to alert ophthalmologists to the occurrence of this tumour in the periocular region, to highlight the importance of surgical excision with wide margins and the need for systemic investigation to exclude a primary malignancy in other sites, in particular the gastrointestinal system and breast.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
2/63. Haemosuccus pancreaticus due to mucinous cystadenocarcinoma: the significance of recurrent abdominal pain, hyperamylasaemia and a pancreatic cyst in association with recurrent gastrointestinal bleeding.Haemosuccus pancreaticus is a rare cause of gastrointestinal haemorrhage, and when it presents in otherwise healthy people, can prove difficult to diagnose. The cardinal features are episodic epigastric pain associated with a raised serum amylase and the passage of melaena. Failure to make the connection between recurrent gastrointestinal bleeding and apparently unrelated symptoms attributable to pancreatitis may lead to a significant delay in diagnosis.- - - - - - - - - - ranking = 60.836938213203keywords = abdominal pain (Clic here for more details about this article) |
3/63. Intraductal papillary-mucinous tumors: an entity which is infrequent and difficult to diagnose.BACKGROUND/AIMS: Intraductal papillary-mucinous tumor of the pancreas is currently considered to be a tumor which is an entity of its own, different from classic pancreatic ductal carcinoma. It is basically characterized by slow growth and low malignancy potential, as well as by the production of mucin. The aim of this study is to contribute to world literature some clarification of its natural history, clinical presentation, the most useful diagnostic tests, methods of detection of stromal invasion and handling of treatment. METHODOLOGY: Of 297 pancreatectomies undertaken at the "12 de Octubre" hospital between May 1985 and January 1998, only 1 case of Intraductal papillary-mucinous tumor was found. We have revised 127 cases published in 10 series over the last 10 years. We also contribute a review of our own case. RESULTS: These tumors, which are very infrequent, produce non-specific symptoms, with long latency periods from the first symptom up to stromal invasion. Endoscopic retrograde cholangiopancreatography showed alterations in 100% of cases where this was undertaken. Tumor-related mortality was zero amongst patients with non-invasive tumor who underwent surgery. None of the cases published presented upper gastrointestinal hemorrhage. This indicated the correct surgery and led us to our diagnosis. CONCLUSIONS: We confirm the low frequency and difficulty of diagnosis, the sensitivity of endoscopic retrograde cholangiopancreatography, the difficulty of early detection of stromal invasion, and the high survival rate in cases where resection is done before this occurs. early diagnosis and treatment is therefore of utmost importance.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
4/63. Mucinous carcinoma of the breast with neuroendocrine differentiation.A case of mucinous carcinoma of the breast with neuroendocrine differentiation in an 89-year-old woman is presented. The patient presented with a rapidly growing right breast mass, which she had had for 2-3 years. The tumor, 15 x 8 x 5 cm, was located mainly in the upper outer quadrant. light microscopy revealed a pure mucinous carcinoma of type B. Neuroendocrine differentiation was demonstrated by Grimelius stain and chromogranin a, as well as the presence of neurosecretory granules. The breast cancer cells were of luminal origin and had dedifferentiated to attain neuroendocrine properties.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
5/63. Validity of local treatment including intraarterial infusion chemotherapy and radiotherapy for fungating adenocarcinoma of the breast: case report of more than 8-year survival.A 39-year-old woman came to us complaining of severe anemia (hemoglobin: 2.3 g/dl) and a painful right breast that was entirely occupied by an ulcerative, foul-smelling tumor approximately 20 cm in maximum dimension. The tumor, which was determined to be mucinous adenocarcinoma at biopsy, had invaded the chest wall with multiple lung metastases (T4cN2M1 stage IV). After a blood transfusion, the patient received the following multimodal treatment: concurrent chemoradiotherapy (50 Gy), intraarterial infusion chemotherapy consisting of doxorubicin 50 mg, mitomycin-C 10 mg, and cisplatin 50 mg, and skin graft surgery. After intraarterial infusion chemotherapy, the fungating tumor disappeared. The patient experienced a relapse of right pleural effusion 2 years later and received multimodal treatment. Now, March 30, 2000, the patient is doing well without local recurrence, 8 years after her first admission. The combination of intraarterial infusion chemotherapy and radiotherapy plays a role in successful treatment of extensive local disease of the breast.- - - - - - - - - - ranking = 0.29132450082389keywords = chest (Clic here for more details about this article) |
6/63. Nodular mucinosis of the breast: a case report with clinical and imaging findings.We present a very rare case of nodular mucinosis of the breast. A 30-year-old woman noticed a right breast lump and consulted at our hospital because it gradually increased in size. On physical examination, the lump was 30 x 25 mm in size, and was located in the upper outer quadrant close to the nipple of the right breast. It was well-demarcated, mobile and hard. ultrasonography (US) showed a clearly circumscribed, lobulated, and homogeneous hypoechoic lesion. mammography (MMG) showed a round-lobular-shaped radiopaque mass without microcalcifications or spicula formation. Fine needle aspiration cytology (FNA) revealed no malignancy and mucin. Histologically, the excised tumor consisted of an abundant myxoid substance with scattered spindle cells without epithelial elements in the mucous lake. The mucinous substance stained positively with alcian blue. Nodular mucinosis, simulating mucinous carcinoma or phyllodes tumor on clinical and imaging examinations, should be included in the differential diagnosis in cases of mucinous lesions occurring near the nipple in a young woman.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
7/63. Intraductal papillary mucinous tumor of the pancreas in a young man: report of a case.We report the rare case of an intraductal papillary mucinous tumor (IPMT) in a man younger than 30 years of age. The patient was admitted with upper abdominal pain and an elevated amylase level of 662 IU/l. ultrasonography showed a cystic mass in the pancreatic body and endoscopic retrograde cholangiopancreatography (ERCP) revealed a dilated pancreatic duct with a filling defect communicating with the tumor. He was successfully treated by segmental resection, which seems to be the best surgical option for pancreatic body tumors since it results in long-term survival and preserves as much pancreatic parenchyma as possible. Nevertheless, it can only be done in the absence of additional nodules along the pancreatic duct. A pathological diagnosis of intraductal papillary adenocarcinoma of the noninvasive type was confirmed, and both stumps were free of tumor.- - - - - - - - - - ranking = 16.209234553301keywords = abdominal pain, upper (Clic here for more details about this article) |
8/63. Successful pre-operative diagnosis of malignant intraductal papillary mucinous tumor of the pancreas by detecting telomerase activity.BACKGROUND: Pre-operative differential diagnosis between benign and malignant intraductal papillary mucinous tumor (IPMT) of the pancreas is markedly difficult by imaging examination. In recent years, telomerase activity has been reported to be detected only in malignant tumors. methods: A 52-yr-old man with abdominal pain was diagnosed with a IPMT through imaging examination. telomerase activity of the pure pancreatic juice, which was obtained pre-operatively by endoscopic retrograde pancreatic juice aspiration (ERPJA), was analyzed by telomeric repeat amplification protocol (TRAP) assay. RESULTS: telomerase activity was detected in the pure pancreatic juice of the patient, who was diagnosed with a malignant IPMT. A pylorus-preserving pancreatoduodenectomy was performed, and subsequent pathological findings revealed the tumor to be adenocarcinoma in adenoma with papillary growth. CONCLUSION: Detection of telomerase activity of the pure pancreatic juice might be useful to distinguish benign from malignant IPMT pre-operatively.- - - - - - - - - - ranking = 15.209234553301keywords = abdominal pain (Clic here for more details about this article) |
9/63. Cystic mucinous adenocarcinoma of the lung. Two cases of cystic variant of mucus-producing lung adenocarcinoma.Two previously unreported cases of mucus-producing lung adenocarcinoma are presented as uncommon tumors, which are clinicopathologically different from other histologic types of lung adenocarcinoma. The tumors, showing apparently rapid development on chest roentgenograms, were tightly packed with copious mucus and resembled cystic lesions. Because they contained very few cancer cells, and these were only at the periphery, it was impossible to diagnose malignant neoplasms preoperatively through cytologic examination. The present tumors, which we described as cystic mucinous adenocarcinoma, are considered to be a cystic variant of mucus-producing lung adenocarcinoma that expands grossly by storing mucus.- - - - - - - - - - ranking = 0.29132450082389keywords = chest (Clic here for more details about this article) |
10/63. Gastric adenocarcinoma presenting as an eyelid and conjunctival mass.A 50-year-old white man complained of "inflammation" of his right eyelid since January 1989. In June 1990, he had undergone a gastrectomy for an adenocarcinoma of the stomach. In August 1990, his right eye showed a painless, firm infiltration of the upper and lower lid, ulceration and loss of eyelashes of the upper lid and a reddish, subepithelial thickening of the medial bulbar conjunctiva. Biopsies of the right upper lid and nasal bulbar conjunctiva disclosed a metastatic, poorly differentiated adenocarcinoma of the stomach (signet ring cell carcinoma) both in the lid and conjunctival biopsies. carcinoembryonic antigen (CEA) was detected in the tumor cells. Electron microscopic examination revealed tumor cells with signs of secretory activity. Although metastases to the eyelids and conjunctiva are rare, they may precede the clinical manifestation of the primary tumor for months or even years. In patients with chronic, recalcitrant lesions of eyelids or conjunctiva, especially if accompanied by loss of eyelashes, a primary or secondary malignancy should be excluded by early biopsies and histopathological examination.- - - - - - - - - - ranking = 3keywords = upper (Clic here for more details about this article) |
