Benign fibrous histiocytoma (BFH) is a benign tumor composed of fibroblasts and histiocytesthat most frequently occur in upper and lower extremities. BFH is rarely found in the area ofhead and neck; especially so in the external auditory canal. The authors have encountered a52-year old male patient with a chief complaint of otorrhea from the right ear. A round, wellcircumscribedmass filled 80% of the right external auditory canal. Non-enhanced temporalbone CT and enhanced temporal bone MRI showed a 0.9×1.0 cm sized dermal or subdermalpolypoid 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 themass showed BFH. We thus report a rare case of BFH of the external auditory canal.
