1/622. Medullary thyroid carcinoma with multiple hepatic metastases: treatment with transcatheter arterial embolization and percutaneous ethanol injection.

    A 54-year-old man with medullary thyroid carcinoma in the thyroid gland was unable to undergo total thyroidectomy because the tumor had invaded the mediastinum. radiation therapy and chemotherapy were given. Seven years later, intractable diarrhea and abdominal pain appeared, and computed tomography demonstrated hypervascular tumors in the thyroid gland and in the liver. The tumors were successfully treated with percutaneous ethanol injection to a lesion in the thyroid gland and transcatheter arterial embolization followed by percutaneous ethanol injection to tumors in the liver. Transcatheter arterial embolization and percutaneous ethanol injection may be valuable in treating medullary thyroid carcinoma.

2/622. Metastatic melanoma of the vulva identified by peritoneal fluid cytology.

    Malignant melanoma of the vulva is an uncommon disease, with a significant portion of cases demonstrating metastasis to inguinal lymph nodes with potential distal spread. Identification of such metastases often requires fine-needle aspiration or biopsy. The cytologic diagnosis of metastatic vulvar melanoma from peritoneal effusions has not been previously described. We present the case of a 54-yr-old woman who underwent en bloc radical vulvectomy with bilateral inguinal lymphadenectomy for melanoma of the right labium minora. No evidence of metastatic disease was identified, and all surgical margins were free of tumor. Despite chemotherapy, the patient returned approximately 2 yr later with abdominal pain and distention. Computed tomography revealed marked ascites and three hepatic lesions. Cytologic examination of the ascites revealed recurrent, metastatic melanoma. Although very rare, metastatic melanoma of the vulva may present as a malignant effusion. In such an event, the diagnosis may be rendered by exfoliative cytology.

3/622. radiation induced liver injury detected by particulate reticuloendothelial contrast agent.

    radiation induced liver injury detected by a particulate reticuloendothelial MR contrast agent is described in a patient with metastatic colon cancer. The irradiated hepatic parenchyma failed to darken after ferumoxide administration. This finding suggests that detection of metastatic disease after ferumoxide contrast agents may be impaired in patients who have previously received upper abdominal radiation treatment.

4/622. A case of biliary cystadenocarcinoma of the liver.

    We describe a case of biliary cystadenocarcinoma of the liver, a very rare malignant tumor, in a 40-year-old man referred to our hospital because of sporadic abdominal pain. A left lobectomy of the liver was performed, and macroscopic examination of the resected specimen revealed prominent papillary projections in a multiloculated cystic tumor containing mucinous material. Histologic examination of the specimen showed a biliary cystadenocarcinoma without mesenchymal stroma, associated with a cystadenoma. cystadenoma with mesenchymal stroma (CMS), which occurs exclusively in women, is generally regarded as a precancerous lesion, and patients with biliary cystadenocarcinoma with mesenchymal stroma have a good prognosis. cystadenoma without mesenchymal stroma arises in both men and women. However, the origin and precancerous lesions of cystadenocarcinoma are unknown. Moreover, the prognosis of patients with biliary cystadenocarcinoma without mesenchymal stroma is poor, especially in men. The cystadenoma without mesenchymal stroma in our patient was considered a precancerous lesion. The present patient has shown no evidence of recurrence in the 8 years after hepatic resection. Previously reported cases of cystadenocarcinoma without mesenchymal stroma, especially those in men, have had a poor outcome. A good outcome in men is very rare.

5/622. A case of aberrant pancreatic cancer in the jejunum.

    We report a case of aberrant pancreatic cancer of the jejunum in a 63 year-old man. The patient was admitted to our hospital with epigastric discomfort and vomiting due to obstruction of the jejunum. laparotomy revealed a submucosal tumor on the jejunum with multiple liver metastases. Histological examination showed the tumor to be a well differentiated tubular adenocarcinoma originating from aberrant pancreatic tissues lacking islets. Only 1 case of aberrant pancreatic cancer in the jejunum has been previously reported in the literature.

6/622. Rapid evolution of chronic viral hepatitis into hepatocellular carcinoma after beta-interferon treatment.

    A 62-year-old man, affected by Chronic Active Hepatitis (discovered in 1993) and treated with interferon, referred to our department with increased abdominal volume, persistent abdominal pain, continuous-remittent fever and jaundice. CT scan of the liver revealed a hypodense, not capsulated, infiltrative, solid formation in the right lobe. US guided biopsy showed multinucleated giant cells, with eosinophilic cytoplasm and pleomorphism of the nuclei, arranged in several thick trabecula lined by endothelial cells or formed bile containing acini. In our case, the rapid evolution of chronic viral hepatitis towards HCC calls for a careful evaluation of the role of IFN therapy, since this drug is widely used in chronic liver diseases.

7/622. Ovarian hepatoid yolk sac tumours: morphological, immunohistochemical and ultrastructural features.

    AIM: The clinicopathological, immunohistochemical and ultrastructural features of two ovarian hepatoid yolk sac tumours (H-YST) from our files are reviewed. methods AND RESULTS: Using avidin-biotin-peroxidase complex technique, the immunoprofile of these tumours was compared to that of a classic yolk sac tumour and to that previously reported for hepatocellular carcinomas. The clinicopathological and morphological features of our cases are similar to the seven previously reported ovarian cases. This rare germ cell tumour occurs in young females (mean age = 17.6 years) and presents most commonly with abdominal pain and a large ovarian mass (average size = 140 mm). Histologically, the tumours display a striking resemblance to hepatocellular carcinoma. The absence of an associated typical pattern of yolk sac tumour or other germ cell neoplasm may make it difficult to recognize the germ cell origin of this lesion. Our cases demonstrated positive staining for alpha-fetoprotein and alpha-1-antitrypsin. In addition, there was immunoreactivity with polyclonal carcinoembryonic antigen (CEA) antiserum in a canalicular pattern, focal staining for inhibin, oestrogen and progesterone receptors and absence of immunoreactivity for CK7 that contrasts with the immunophenotype of a usual yolk sac tumour. CONCLUSIONS: Ovarian H-YST and hepatocellular carcinoma share a similar immunoprofile. Ovarian H-YST is a highly aggressive tumour, most patients exhibit recurrence or die of disease within 2 years of diagnosis.

8/622. An unusual cause of back pain.

    This case describes what may become an increasingly common clinical problem in australia as the proportion of our population originally derived from South East asia, ages. Our patient was of Chinese origin and presented with back pain which was eventually found to be due to metastatic disease from an otherwise silent hepatoma, in association with unrecognised chronic hepatitis b infection.

9/622. Successful surgical treatment for implanted intraperitoneal metastases of ruptured small hepatocellular carcinoma: report of a case.

    We report herein the case of a 53-year-old man with disseminated intraperitoneal metastases caused by the rupture of small hepatocellular carcinoma (HCC). He was admitted to our hospital in shock after suffering a trauma injury to the upper abdomen. ultrasonography revealed a massive hemoperitoneum. At surgery, 4000 ml of blood was drained from the abdominal cavity and a ruptured tumor, 2 cm in diameter, was found in the right lobe of the liver. The tumor was resected with an adequate surgical margin and subsequent microscopic examination confirmed a diagnosis of moderately differentiated HCC without associated liver cirrhosis. The patient was readmitted 14 months later following the development of right lower quadrant pain. ultrasonography and computed tomography revealed extrahepatic abdominal tumors, and abdominal angiography demonstrated four intraperitoneal tumors. At surgery, four implanted metastases adhered to the greater omentum were found and resected. No other tumors were detected. Microscopically, all four tumors were confirmed as moderately differentiated hepatocellular carcinoma. Ruptured HCC may lead to implanted intraperitoneal metastasis, but rupture of small HCC is very rare. While hepatic resection is the treatment of choice for ruptured HCC, according to our review of the literature, only a few patients have survived long-term after resection of implanted metastasis.

10/622. Primary liver carcinoma complicating membranous obstruction of the inferior vena cava.

    A rare autopsy case of primary liver carcinoma complicating a pre-existing, incomplete membranous obstruction of the inferior vena cava (MOVC) is reported. The patient, a 67-year-old Japanese male, was admitted to hospital following a 2 year illness of a left chest wall tumor and a 3 month illness with progressive abdominal pain. Computed tomography scans of the abdomen displayed space-occupying lesions in the third and seventh hepatic segments, respectively. One month later, the patient developed edema of the lower extremities and marked venous dilatation of the abdominal trunk. At that time, Doppler examination revealed the presence of intrahepatic large venovenous collaterals. The patient subsequently succumbed 82 days after hospitalization. At subsequent autopsy, the inferior vena cava was completely obstructed by tumor thrombus, which was formed caudally and cranially to a thin membrane and mimicked the valve, with calcification and elastic lamina, at the phrenic portion. Intrahepatic large collateral pathways were found between submembranous and supramembranous hepatic veins. Anomalous absence of the ostia of the middle hepatic vein was found. In addition, the portal venous trunk was occluded by tumor thrombus. histology of hepatic tumors revealed a combined hepatocellular and cholangiocellular carcinoma in the non-cirrhotic liver with severe acute centrilobular congestion. In MOVC patients such as the case presented, malignancy-induced thrombosis was deemed to be an important factor in prognosis.
