Angiosarcoma accounts for 1% of all soft tissue sarcoma. Common sites of occurrence include the skin, breast, soft tissue, and liver. It metastasizes to the lungs, bone, and spleen. The cause of hepatic angiosarcoma in the 60% of cases is unknown, although specific risk factors such as vinyl chloride, arsenic, thorotrast and external-beam irradiation have been identified. Since 1986, about eight cases of hepatic angiosarcoma have been reported in Korea, but it had not been reported in which the hepatic angiosarcoma invaded to the stomach, yet. So we report a case of histopathologically confirmed primary hepatic angiosarcoma with gastric involvement. In this case, a sixtythree-year-old female was presented with indigestion and epigastric soreness for 1 year. Endoscopic examination of the stomach revealed a submucosal tumor-like protruding mass from the antrum to angle. The mucosal surface showed severe hyperemia and shallow ulcerative change was seen. Endoscopic biopsy and percutaneous liver biopsy confirmed the diagnosis of hepatic angiosarcoma invading the gastric wall.

In spite of its rarity, hepatic angiosarcoma is of special interest because specific risk factors such as thorium dioxide, arsenic, and vinyl chloride have been identified. We report a case of histopathologically confirmed primary angiosarcoma of the liver which was found in a farmer. In this case, 73-ear old man was presented with right upper abdominal pain and fatigue. Abdominal ultrasonography, CT scan and MRI revealed a mass occupying broad area of the right lobe of the liver. Histopathologic diagnosis of angiosarcoma was made by percutaneous needle biopsy.
