title: [Primary epithelioid adrenal angiosarcoma mimicking undifferentiated carcinoma].
abstract: The adrenal primary epithelioid angiosarcoma (ASE) is a rare malignant tumor which can be histologically confused with other neoplasms. We report one case in a 79-year-old man who underwent adrenal tumor surgery for a mass fortuitly discovered by imaging for examination of an inflammatory syndrome associated with anemia. The histological diagnosis was difficult because of the undifferentiated and epithelioid appearance of tumor cells, whose immunohistochemical epithelial markers positivity led to frequent confusion with a metastatic carcinoma. Careful research for vascular differentiation at histopathological study and expression of immunohistochimical endothelial markers, are crucial to confirm the diagnosis.
