Abstract

Hepatocellular carcinoma (HCC) is usually associated with chronic liver disease such as liver cirrhosis. Primary HCC lesions and even recurrent intrahepatic lesions can be treated successfully by using variable modalities applicable to intrahepatic lesions. HCC can cause intrahepatic multiple occurrence and extrahepatic metastasis. Extrahepatic metastasis occurs in up to about 60% of patients of HCC, and a major of patients with extrahepatic HCC had late intrahepatic stage of tumor. Themost frequent site of extrahepatic metastasis of HCC was the lung. HCC metastasized to soft tissues was unusually reported. Extrahepatic metastasis of HCC, especially to unusual site, should not be overlooked and must be able to be controlled. We experienced a case that HCC was metastasized to the pronator quadratus muscle of right wrist and chould be removed surgically.
