Abstract

Epithelioid angiosarcoma is a rare high-grade tumor with irregular vascular morphology. We report an unusual case of intra-abdominal epithelioid angiosarcoma affecting the omentum and peritoneal surfaces resulting in significant hemorrhagic and inflammatory changes. As in other cases of this tumor this patient had previously undergone radiation treatment for a history of cervical cancer.
