Solitary fibrous tumor (SFT) is a rare benign spindle-cell neoplasm, most often found in the pleura. Recently, it has been reported to appear throughout the body but rarely in head and neck region. Tumors in the external auditory canal, in particular, have been very rarely reported. We experienced a case of a 55-year-old male with a 6-month history of progressive swelling from the orifice of left external auditory canal. The tumor was round, well circumscribed, almost completely obstructing the left external auditory canal. On the enhanced temporal bone CT and enhanced paranasal sinus MRI, a 2.0×1.7 cm sized mass was observed at the left external auditory canal. He was treated with surgical excision under general anesthesia. Histopathologic examination confirmed the diagnosis of SFT. This case report presents a rare case of a SFT arising in the external auditory canal.
