Abstract

We reported a case of an 80-year-old woman with angiosarcoma on the abdomen. She had received a subwide-range total hysterectomy and postoperative irradiation at age of 72 for the uterin cancer. She noticed a subcutaneus induration on the abdomen since then. She was referred to us for a red black tumor on the induration of three months duration. Total resection of the tumor, irradiation and immunochemotherapy with IL-2 were performed under the diagnosis of angiosarcoma. Nine months later, two tumors as same as the first one recurred near by the primary lesion. Irradiation and immunotherapy had some good effect to reducing the size of the tumors. We speculated that the healing process of endthelial cells after irradiation damages might be related to the occurrence of angiosarcoma.
