  • Look Inside

 The authors experienced 10 patients with benign tumors in the external ear canal for two years and six months between January in 1980 and June in 1982 at the out-patient clinic of our University Hospital. This accounted for 0.05% of the total out-patients. Ten patients consisted of three with fibroma, two with osteoma, two with atheroma, two nevus pigmentosus and one with papilloma. There were four males and six females.

 One of three fibromas, a 37-year-old female patient, developed cellular type of dermatofibroma at the entrance of external ear canal. This histological type is extremely rare among fibroma which is also rare among benign tumors appearing in the external ear canal.
