title: [Gastric epithelioid angiosarcoma, a biopsy diagnostic pitfall].
abstract: We report the case of a 70-year-old man who presented a bulky gastric mass. The diagnosis of poorly differenciated adenocarcinoma was made on the biopsy. On surgical specimen, the final diagnosis of gastric angiosarcoma with secondary intestinal involvement was established. The patient did not respond to chemotherapy and died 8 months later. The diagnosis was difficult because of epithelioid areas which expressed both cytokeratin and vascular antigens. Human herpesvirus 8 previously detected in some soft tissue angiosarcoma was not found by polymerase chain reaction.
