A case of angiosarcoma which was difficult to differentiate from peliosis hepatis

Abstract

A 73-year-old woman who went to hosipital by peliosis hepatis regularly admitted to our hospital for aggravation of ascites and enlargement of liver tumor. She died with rapid progression to liver failure after a month in a hospital. The results of autopsy showed that the liver tumor was hepatic angiosarcoma and it caused extensive intraabdominal hemorrhage. Although peliosis hepatis is benign tumor, hepatic angiosarcoma is poor-prognosis tumor which does not have any confirmed treatments. Since both of them are included differential diagnosis of hepatic tumors, they should be diagnosed definitely by pathological procedure.
