The epithelioid hemangioendothelioma is an uncommon vascular neoplasm. Numerous sites of involvement are possible, but these tumors most commonly arise in the soft tissues, liver, and lung. We report a case of epithelioid hemangioendothelioma presenting as a single lesion on the nasal portion of the maxilla. Histologically, the tumor within bone and skin exhibited cords and nests of plump, epithelioid-appearing cells exhibiting rudimentary vascular differentiation within a myxohyaline stroma. Immunohistochemical reactivities for factor VIII-related antigen, CD31, CD34, and vimentin were demonstrated. Wide local excision with close clinical follow-up seems to be the treatment of choice for these tumors.

Abstract
The epithelioid hemangioendothelioma is an uncommon vascular neoplasm. Numerous sites of involvement are possible, but these tumors most commonly arise in the soft tissues, liver, and lung. We report a case of epithelioid hemangioendothelioma presenting as a single lesion on the nasal portion of the maxilla. Histologically, the tumor within bone and skin exhibited cords and nests of plump, epithelioid-appearing cells exhibiting rudimentary vascular differentiation within a myxohyaline stroma. Immunohistochemical reactivities for factor VIII-related antigen, CD31, CD34, and vimentin were demonstrated. Wide local excision with close clinical follow-up seems to be the treatment of choice for these tumors.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
