Epithelioid hemangioendothelioma of middle ear masquerading as glomus tumor.

Hemangioendothelioma is still one of the less-known tumors of vascular origin. The authors report the case of a 38-year-old man who presented with unilateral, nonpulsatile timnitus, aural fullness, and a sense of imbalance. Imaging showed a contrast enhancing soft tissue mass lesion involving the external auditory canal and middle ear, mimicking as glomus tumor. Histopathological examination of surgical specimen showed it to be hemagioendothelioma.
