Malignant epithelioid hemangioendothelioma: a case report.

Malignant epithelioid hemangioendothelioma (EH) is a rare tumor of vascular origin. We report a case of a woman who was found to have multiple hepatic masses in the right lobe of the liver on radiologic investigations, initially misdiagnosed as a metastatic carcinoma. The diagnosis of EH was made on histopathological study and confirmed by immunohistochemistry, which showed diffuse response for CD34 marker and no response to tissue CEA, HMB-45 or S-100 protein. Partial hepatectomy was made with good results.
