Abstract:
Cartilaginous choristoma of bony external auditory canal is very rare. Appearing as a horny sha-ped hard mass, cartilaginous choristoma can be found in the medial portion of anterior wall of external auditory canal. Histologically, it consists of adult-type hyaline cartilage without neoplastic features. If cartilaginous choristoma shows growing tendency or ear symptoms, surgical excision would be the treatment of choice. Here, we report a case of cartilaginous choristoma that occurred in the external auditory canal in an 8-year-old boy.
