Percutaneous laser ablation of hepatocellular carcinoma in patients with liver cirrhosis awaiting liver transplantation.

Objective: The aim of this study was to determine the effectiveness and safety of percutaneous laser ablation for the treatment of cirrhotic patients with hepatocellular carcinoma awaiting liver transplantation.

Materials And Methods: The data of 9 male cirrhotic patients (mean age 50 years, range 45-60 years) with 12 biopsy proven nodules of hepatocellular carcinoma (mean diameter 2.0 cm, range 1.

Primary yolk sac tumor of the liver: incidental finding in a patient transplanted for hepatocellular carcinoma.

A 64-year-old man with HBV-related cirrhosis presented with a liver nodule measuring 2.8 cm revealed by a routine ultrasound and concomitant increased alpha-fetoprotein (AFP) up to 400 UI/l. Contrast-enhanced CT was suggestive of hepatocellular carcinoma (HCC) and the patient underwent laser ablation procedure.

Multifocal epithelioid angiosarcoma of bone: a potential pitfall in the differential diagnosis with metastatic carcinoma.

A case of multifocal epithelioid angiosarcoma of the femur, tibia, fibula, and astragalus in a 54-year-old man is reported. The tumor was composed of nests and cords of malignant cells with epithelioid morphology, with foci of vascular differentiation, necrosis, and hemorrhage. By immunohistochemistry, the neoplastic cells showed positivity for endothelial cell markers (CD31, CD34, factor VIII-related antigen, and Ulex europaeus agglutinin I), epithelial markers (cytokeratins and epithelial membrane antigen), and vimentin.
