Weiss and Enzinger first described epithelioid hemangioendothelioma (EHE), a rare vascular tumor, in 1982 as a clinical state between hemangioma and angiosarcoma.We present here a 40-year-old female with complains of pain and swelling over the right arm since five years. Intraoperative findings revealed a mass arising from the brachial artery. Histopathological examination, revealed, proliferation of chains and cords of epithelioid endothelial cells distributed in a myxohyaline stroma. The cells had eosinophilic cytoplasm containing vacuoles that deformed the cytoplasm. Some vacuoles contained fragmented erythrocytes.On immunohistochemistry, the tumor cells were positive for CD34. A final histopathological diagnosis of epithelioid hemangioendothelioma (low grade) was made. Epithelioid hemangioendotheliomas, especially primary vascular ones, are extremely rare, with 33 cases reported in English literature. Surgery seems to be the only beneficial treatment, with a doubtful role of chemotherapy and none for radiotherapy.....
