1/84. Quadruple cancer including bilateral breasts, Vater's papilla, and urinary bladder: report of a case.

    We herein report a rare case of quadruple carcinoma with heterochronous bilateral breast cancer, cancer of Vater's papilla, and cancer of the urinary bladder, which were all curatively resected. A 62-year-old woman previously underwent right and left modified radical mastectomies heterochronously. Recently, a dilatation of the lower bile duct, diagnosed as cancer of Vater's papilla, was resected by a pancreatoduodenectomy. hematuria during surgery led to the discovery of a solid bladder tumor. The tumor was resected by a transurethral resection. The histopathologic findings differed for all four lesions. The patient had an uneventful postoperative course and to date has shown no recurrence.

2/84. Mucin Hypersecreting Intraductal Papillary Neoplasm of the pancreas.

    Mucin Hypersecreting Intraductal Papillary Neoplasm is a rare neoplasm that arises from ductal epithelial cells. This entity is distinct from the more commonly known Mucinous cystadenoma or Mucinous cystadenocarcinoma. Despite this distinction, it has been erroneously categorized with these more common cystic neoplasms. Characteristic clinical presentation, radiographic, and endoscopic findings help distinguish this neoplasm from the cystadenomas and cystadenocarcinomas. Histopathologic identification is not crucial to the preoperative diagnosis. This neoplasm is considered to represent a premalignant condition and, therefore, surgical resection is warranted. prognosis, following resection, is felt to be curative for the majority of patients. We present two cases of Mucin Hypersecreting Intraductal Papillary Neoplasm and discuss their diagnosis and surgical therapy.

3/84. Synchronous carcinoma of the gallbladder in a patient with intrahepatic bile duct carcinoma.

    An 83-year-old woman, diagnosed as having cholelithiasis, was admitted to the Department of Surgery, Nippon Medical School, with right hypochondrial pain. ultrasonography and computed tomography revealed a mass in the gallbladder fundus and a hypovascular tumor in the anterior segment of the liver. magnetic resonance imaging showed stenosis of the intrahepatic bile duct and dilatation of its proximal portion. She was diagnosed as having intrahepatic bile duct carcinoma combined with gallbladder carcinoma. At laparotomy, there was evidence of multiple peritoneal metastases and intraoperative histological examination of the gallbladder tumor revealed adenocarcinoma. Accordingly, only cholecystectomy and needle biopsy of the liver tumor was performed. Histological examination of the gallbladder revealed papillary adenocarcinoma invading the muscularis propria with medullary growth or intermediate stroma. There was no microvessel invasion, no perineural invasion and no lymph node involvement. On the other hand, the liver tumor was a cholangiocarcinoma with a well-differentiated tubular pattern. Therefore, this was a rare case of synchronous carcinoma of the gallbladder associated with intrahepatic bile duct carcinoma.

4/84. Biliopancreatic fistula associated with intraductal papillary-mucinous pancreatic cancer: institutional experience and review of the literature.

    Intraductal papillary-mucinous tumour is clinicopathologically characterized by papillary growth and mucin production within the pancreatic duct system. The category includes a wide range of dysplasia, ranging from adenoma to carcinoma, the latter designated as intraductal papillary-mucinous cancer. In general, the tumor renders a favorable prognosis after complete resection. However, intraductal papillary-mucinous tumor with overt invasion outside the gland has been reported to have a poor prognosis, as is the case with the usual type of duct cell cancer of the pancreas. We experienced two cases of intraductal papillary-mucinous cancer with obstructive jaundice due to impaction of thick mucus protruding from the pancreas via a "spontaneous" biliopancreatic fistula. Preoperative examinations of both patients showed a large intraductal papillary-mucinous tumor in the head of the pancreas with fistula formation between the intrapancreatic portion of the common bile duct and the main pancreatic duct. Histopathological investigation of the two resected specimens suggested that the fistula may not have developed from invasion by papillary or tubular adenocarcinoma, but from compression and destruction of the intercalating tissues by abundant mucinous secretion. The first patient died of peritoneal carcinomatosis with clinicopathologic features of pseudomyxoma peritonei 6 years after surgery. The second patient is alive and has been well for 2 years postoperatively. review of the world literature showed that half of the patients with intraductal papillary-mucinous cancer plus biliopancreatic fistula had no stromal invasion around the fistula, indicating that the fistula might have been caused by mechanical pressure. However, the other half of the cases did have stromal invasion around the fistula. Two-thirds of these cases, including our own patients, had foci of mucinous carcinoma in the stroma around the fistulization, implying that mucinous lakes in the stroma may have served as part of the "waterway" from the pancreatic duct to the bile duct, assisted by increased pressure by mucus production. Since intraductal papillary-mucinous cancer with biliopancreatic fistula has a comparatively favorable prognosis, surgical resection should be considered.

5/84. Papillary adenocarcinoma of the thyroid in a thyroglossal duct cyst.

    A case report is presented of an 8-year-old boy who underwent resection of a thyroglossal duct cyst to illustrate a rare, but significant, complication of a common clinical problem. Pathological examination revealed that it contained a papillary adenocarcinoma of the thyroid, presumably arising from ectopic glandular tissue in the cyst. Thyroglossal duct cysts are a common cause of midline neck masses in children. Occult thyroid carcinoma is a rare co-morbid finding. It infrequently leads to death, but thyroglossal duct cysts may also contain the only functioning, albeit ectopic, thyroid tissue. patients with clinical thyroglossal duct cysts should be carefully evaluated preoperatively for the presence of tumor and other functioning thyroid tissue prior to excision of the cyst.

6/84. Ampullectomy of carcinoma of the papilla of vater in an elderly patient without jaundice.

    A 79 year-old woman was admitted to Aioi City Hospital for a closer examination of hepatic dysfunction. A filling defect was observed at the distal end of the intrapancreatic common bile duct by computed tomography combined with drip infusion cholangiography. The diagnosis of adenoma with dysplasia at the papilla of Vater was obtained by a biopsy performed during duodenoscopy. As a result, we performed an ampullectomy. Histologic examination revealed a papillary adenocarcinoma which partly extended just beyond the muscle of Oddi. The patient made an uneventful recovery and was discharged on the 35th postoperative day. Here, based upon our experience, we discuss such problems as the accuracy of preoperative diagnosis and the indications for ampullectomy.

7/84. Long-term survival of a patient with fallopian tube cancer presenting with a supraclavicular mass.

    BACKGROUND: Five-year survival of patients with stage IV cancer of the fallopian tube is poor. Furthermore, patients with gynecological cancers presenting with a supraclavicular mass generally have an unfavorable prognosis. CASE REPORT: We describe a 70-year-old patient who presented with a left supraclavicular mass. The mass was removed and histology showed metastatic papillary adenocarcinoma strongly suggestive of papillary serous carcinoma. Abdominal hysterectomy and salpingo-oophorectomy showed a primary carcinoma of the fallopian tube. Postoperatively the patient received six cycles of carboplatin-based chemotherapy and is alive and well with no evidence of disease 5 years and 10 months after the primary diagnosis. CONCLUSION: Surgery and adjuvant carboplatin-based chemotherapy seem justified even in older patients with fallopian tube cancer and distant metastasis at the time of diagnosis.

8/84. Spontaneous necrosis of gallbladder carcinoma in patient with pancreaticobiliary maljunction.

    While gallbladder carcinoma is occasionally associated with pancreaticobiliary maljunction, spontaneous necrosis of carcinoma is extremely rare. We herein present a case of spontaneous necrosis of gallbladder carcinoma associated with direct invasion of viable cancer cell nests to the muscularis propria and subserosal layer located beneath the primary nodules. A 65-year-old Japanese man was admitted to a local hospital, complaining of repeated discomfort in the right hypochondrium. ultrasonography and computed tomography scanning revealed cholecystitis associated with gallstones. cholecystectomy was performed, and operative cholangiography demonstrated pancreaticobiliary maljunction. The resected gallbladder showed multiple mixed stones filled with necrotic debris and bile sludge. Scrutiny of the mucosal surface revealed multiple small necrotic nodules in the fundus, which were histologically confirmed to be necrotic remnants of a cancerous glandular structure. Small nests of papillary adenocarcinoma were found beneath the nodules in the muscularis propria and in the venous structure located in the connective tissues next to the divided margin of the gallbladder bed. Resection of S4a and S5 of the liver and resection of the extrahepatic bile duct was then performed to remove the remaining cancerous tissues and/or micrometastasis in the liver and bile duct. The biliary tree was reconstructed with a hepaticoduodenostomy. No cancer nests or any precancerous lesions were found in the additionally resected specimens. This case indicates a unique morphological feature of gallbladder carcinoma associated with pancreaticobiliary maljunction, which provides some insight into the pathogenesis of spontaneous necrosis of gallbladder carcinoma.

9/84. Malignant struma ovarii with thyrotoxicosis.

    BACKGROUND: Malignant struma ovarii is seldom diagnosed preoperatively due to the rarity of the disease itself and the even rarer complications of thyrotoxicosis. CASE: A 48-year-old woman presented with symptoms of hyperthyroidism and a pelvic tumor raising the possibility of ovarian malignancy. Hormonal findings revealed increased thyroid function, but the thyroid gland was normal in size and texture. Thus, she was diagnosed preoperatively as having a hormone-producing malignant struma ovarii. At surgery, a FIGO stage Ia ovarian papillary adenocarcinoma of the thyroid was found. An immunohistochemical tumor stain for thyroglobulin was positive and the ovarian venous thyroglobulin level was extremely high. Findings of hyperthyroidism disappeared over several weeks. CONCLUSION: Malignant struma ovarii can be diagnosed preoperatively. Complications of thyrotoxicosis should be kept in mind when evaluating an ovarian tumor.

10/84. endolymphatic sac tumour. A case report.

    We present the case of a patient with an endolymphatic sac tumour (ELST). This rare tumour entity has only recently been defined and despite a well characterized clinical appearance misdiagnosis as jugular paraganglioma is frequent. A 68-year-old woman was admitted to our Neurosurgical Department with a mass lesion extending from the left temporal bone to the cerebello-pontine angle (CPA). Radiological features were high vascularization, contrast enhancement and destruction of the os petrosum. After preoperative angiographic embolization the tumour was removed in two surgical interventions, first via a lateral suboccipital approach and second by petrosectomy. The lesion proved to be a typical endolymphatic sac tumour by a synopsis of histological, radiological and clinical features. ELST should be taken into consideration in patients with mass lesions in the cerebellopontine angle destroying the petrous bone and resembling paraganglioma. Since slow growth rate and lack of metastases are particular features of ELST, complete resection of the tumour results in long survival times without adjuvant chemo- or radiotherapy.
