1/3010. Solitary hepatic hemangioma in a newborn infant complicated by cardiac failure, consumption coagulopathy, microangiopathic hemolytic anemia, and obstructive jaundice. Case report and review of the literature.

    A newborn infant with a large hepatic hemangioma developed congestive heart failure, consumption coagulopathy, microangiopathic hemolytic anemia, and obstructive jaundice. The patient was mildly heparinized (250 units per kg and day) and underwent successful resection of the tumor without lobectomy at the age of 3 days. blood volume increased from 93.9 ml/kg at the age of 5 h to 124.2 ml/kg prior to surgery. Red-cell mass simultaneously decreased from 53.8 to 39.4 ml/kg. The increase of blood volume is explained by congestive heart failure, the decrease of red-cell mass by intravascular coagulation within the tumor resulting in formation of thrombi and microangiopathic hemolytic anemia. A review of the literature on infants with symptoms caused by an intrahepatic hemangioma during the first month of life confirms that surgical intervention is the treatment of choice for infants with giant solitary hemangioma of the liver.

2/3010. Intact PTH-producing hepatocellular carcinoma treated by transcatheter arterial embolization.

    We report a case of hepatocellular carcinoma with hypercalcemia. There was no evidence of bone metastasis or increase in parathyroid hormone-related protein. The serum level of intact parathyroid hormone (intact PTH) was very high, and the results of the hepatic venous sampling suggested that the tumor produced intact PTH. Transcatheter arterial chemoembolization effectively controlled the humoral hypercalcemia.

3/3010. Development of an Epstein-Barr virus type 2 (EBV-2)-associated hepatic B cell non-Hodgkin's lymphoma in an hiv-1-infected patient following a change in the EBV dominant type.

    From the longitudinal study of a cohort of HIV-positive patients, we report the case of a patient who initially harbored the Epstein-Barr virus (EBV) type 1 and subsequently developed an EBV-2-associated non-Hodgkin's B lymphoma a few years after an EBV-2 reactivation, or an exogenous reactivation, in the blood. At the time of diagnosis of hepatic lymphoma, the blood and the throat harbored high levels of the EBV-1 dominant strain. sequence analysis of EBNA-2 gene revealed that: (1) type 2 EBV detected during reactivation and then in hepatic tumor was very likely to be the same strain and was mostly identical to the EBV prototype AG876; (2) type 1 virus conserved the same mutations during all the follow-up. These results suggest that EBV-2 might be associated with lymphomatogenesis and that a transient reactivation could lead to the development of an EBV-associated disease.

4/3010. A case of primary lymphoma of the liver.

    A case of primary malignant lymphoma of the liver is described. Presenting with epistaxis, he died in hepatic encephalopathy with an intractable bleeding post-bulbar duodenal ulcer.

5/3010. 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.

6/3010. Premalignant lesions and hepatocellular carcinoma in a non-cirrhotic alcoholic patient with iron overload and normal transferrin saturation.

    A 66-year-old white man had a hepatic resection for a 6-cm well-differentiated hepatocellular carcinoma which had developed in a non-cirrhotic liver. The only risk factors found were heavy drinking, smoking and heterozygosity for the C282Y mutation of the HFE gene. The liver was mildly fibrotic and overloaded with iron. It also contained numerous iron-free hepatocellular lesions from <1 to 10 mm, suggesting a premalignant change. These lesions were of three types: (i) iron-free foci, (ii) hyperplastic nodules and (iii) dysplastic nodules with severe dysplasia or even foci of well-differentiated grade I hepatocellular carcinoma. This observation suggests the possibility of malignant transformation of the liver in the newly-described syndrome of iron overload and normal transferrin saturation. It also illustrates the multistep process of carcinogenesis in the non-cirrhotic liver.

7/3010. Primary yolk sac tumour of the liver in adulthood.

    Primary yolk sac tumour of the liver is exceedingly rare. A 28 year old woman presented with a cystic liver mass and a markedly raised serum alpha-fetoprotein concentration. She underwent a partial hepatectomy for a suspected hepatocellular carcinoma but histological examination of the tumour revealed the classical morphological and immunohistochemical features of a yolk sac tumour. There was no evidence of an extrahepatic primary source. review of this case, together with the six previously reported adult cases of primary yolk sac tumours of the liver, revealed several features of the tumour that may aid differentiation from hepatocellular carcinoma, with potential therapeutic implications.

8/3010. Prolonged lactic acidosis after extended hepatectomy under in situ hypothermic perfusion.

    A 46-year-old woman underwent right extended hepatectomy under total vascular occlusion with in situ hypothermic perfusion for colorectal metastasis. Immediately after surgery, she developed severe lactic acidosis, which required correction with sodium bicarbonate solution and ventilatory support for 36 hours. After 2 days, her lactate normalized, and the acidosis was corrected. She made an uneventful recovery. Persistent lactic acidosis after major hepatic resection under in situ hypothermic perfusion is a rare but reversible problem.

9/3010. Primary hepatic angiosarcoma: report of a case involving environmental arsenic exposure.

    Hepatic angiosarcoma is a rare malignant tumor with a rapidly fatal course. It has become a subject of interest because of its intimate relationship with environmental carcinogens, such as thorium dioxide (Thorotrast), vinyl chloride monomer, and arsenic. We describe a case of a chronic hepatitis b surface antigen carrier, with a 20-year history of environmental exposure to arsenical-containing agricultural herbicides and bactericides, who developed a hepatic angiosarcoma. He died due to rupture of the hepatic angiosarcoma with acute hemoperitoneum 9 weeks after initial diagnosis. This is a rare case of primary hepatic sarcoma, especially in taiwan where hepatocellular carcinoma is endemic. This case not only serves to give more evidence of the relationship between hepatic angiosarcoma and arsenical exposure, but also demonstrates the key point in the differential diagnosis of liver tumors. Increased familiarity with this disease will facilitate correct diagnosis and help to improve management of the condition in the future.

10/3010. Primary hepatic carcinoid in a renal transplant patient.

    There seems to be a world-wide increase in the incidence of tumors among immunosuppressed patients. Of 1350 renal allografts transplanted in the past 23 years at the Department of transplantation and Surgery, 56 cases were malignant tumors. The case of a 58-year-old female patient is reported, with disseminated primary carcinoid in the liver detected 86 days after renal transplantation. According to the literature only 39 patients with primary liver carcinoids have been reported until 1997, but this is the first where the carcinoid developed in an immunosuppressed patient. The rapid progression of the carcinoid could be associated with the immunosuppression.
