Chondroma of the bony external auditory canal attached to the short process of the malleus.
A chondroma located in the external auditory canal is a rare finding. Here, we report the case of a 12-year-old girl who attended our clinic with complaints of a rustling sound in her left ear. Otoscopic examination revealed a tiny bone-like tumor protruding from the anterior wall of the bony external auditory canal, attached to the short process of the malleus. An audiogram revealed a conductive hearing loss in her left ear, although she did not notice it. After excision of the tumor through the ear canal, her complaints disappeared and her hearing recovered. Histologically, the tumor proved to be a chondroma.
