ABSTRACT
Angiosarcoma is a very rare neoplasm, and even more so in the gastrointestinal tract where its distinction from adenocarcinoma may be extremely difficult. We report a case of multifocal epithelioid angiosarcoma of the stomach in a 65-year-old woman. Histologically, the tumor foci were composed of haphazard, anastomosing channels lined by malignant endothelial cells with epithelioid features. Those neoplastic cells stained positive for CD31, CD34, and factor VIII-related antigen.
Key Words: Angiosarcoma; Stomach
