Epithelioid hemangioendothelioma

Epithelioid hemangioendothelioma (eHAE) is a rare tumor, first characterized by Sharon Weiss and Franz Enzinger that both clinically and histologically is intermediate between angiosarcoma and hemangioma. However, a distinct, disease-defining genetic alteration recently described for EHE indicates that it is an entirely separate entity from both angiosarcoma and hemangioma. [Source: Wikipedia ]
