Abstract
|
|
|
|
A benign fibrous histiocytoma is a tumor with fibroblastic and histiocytic differentiation, most commonly found in soft tissues or adult bones. Its occurrence in the ear is, however, extremely rare, and there hasn’t been any report on the case originating from the middle ear. We experienced a case of 37-year old male patient who complained of intermittent otorrhea and hearing loss. The patient had an 1×1 cm-sized mass in the right mastoid antrum in the temporal bone CT. Under the impression of cholesteatoma or benign tumor, a mass removal was done. A histopathologic investigation of the resected tumor showed typical features of benign fibrous histiocytoma. We herein report along with a brief literature review a case of benign fibrous histiocytoma arising in the mastoid antrum.
