Benign lesions of the hand simulating angiosarcoma: Masson's vegetating intravascular hemangioendothelioma

The authors report a case of intravascular hemangio-epithelioma vegetans of Masson. Usually a tumor of the head and neck. This case was characterized by the presence of two independent tumors on the same hand. On the cases of the 86 cases reported in the world literature, the authors suggest a primary endothelial origin for this benign tumor.
