Giant Extrahepatic Hepatocellular Carcinoma-Report of Three Cases

Abstract

Extrahepatic cancer is a relatively rare disease. Its pathogenesis has not been clarified. Its diagnosis and treatment are said to be different from those of the usual hepatoma. We encountered three cases of extrahepatic hepatocellular carcinoma. Case 1 is that of a 38-year-old woman. Her pedunculated tumor was resected by partial hepatectomy. She is alive 4 years and 9 months after the operation. Case 2 is also that of a 39-year-old women. Her pedunculated tumor accompanied by chronic hepatitis was resected by partial hepatectomy. She is alive 2 years and 8 months after the operation. Case 3 is that of a 61 years old man. His protrusive tumor associated with multiple tumors in a cirrhotic liver was resected by left hepatectomy. He died 7 months after the operation. Angiography is suggested as a superior diagnostic procedure along with ultrasonography, computed tomography and examination for tumor markers. Prognosis for a pedunculated tumor is better than for a protrusive tumor after surgery.
