Abstract:
Epithelioid angiosarcoma has recently been described as a variant of angiosarcoma, based on its pathologic feature which is characterized by epithelioid or histiocytoid morphology of the malignant tumor cells. We report a case of epithelioid angiosarcoma on the lower back of a 65-year-old man. The patient had several, variable-sized, pedunculated, fungating masses. On histopathologic examination, the tumor was chiefly composed of solid sheets of atypical epithelioid cells with prominent eosinophilic cytoplasm, a large vesicular nuclei, and occasional intracytoplasmic vacuoles. Primitive vascular spaces, and a cleft with malignant cells and proliferating vessels were also found in some areas. The reticulum stain and immunohistochemical stain using factor VII-related antigen and CD 31 were focally positive in the tumor. He was treated by wide surgical excision.
