ABSTRACT
Benign fibrous histiocytoma (BFH) is a benign tumor composed of fibroblasts and histiocytes that most frequently occur in upper and lower extremities. BFH is rarely found in the area of head and neck; especially so in the external auditory canal. The authors have encountered a 52-year old male patient with a chief complaint of otorrhea from the right ear. A round, wellcircumscribed mass filled 80% of the right external auditory canal. Non-enhanced temporal bone CT and enhanced temporal bone MRI showed a 0.9×1.0 cm sized dermal or subdermal polypoid mass arising at the right anterosuperior external auditory canal. Under local anesthesia, the patient underwent a complete resection of the mass, and the pathological result of the mass showed BFH. We thus report a rare case of BFH of the external auditory canal.
