Abstract
Dermoid cyst of the helix is a rare disease, with 1 case having been reported in the world in the past 20 years. We experienced a case of dermoid cyst of the helix combined with cryptotia. An 8 month-old-girl was admitted to our hospital with the chief complaint of right ear deformity. During the operation for cryptotia, we chanced to find a tumor near the base of the helix and excised it. We then corrected the cryptotia deformity by the method that Hosaka had previonsly reported. Histopathology revealed tumor to be a dermoid cyst. Three years after the operation, the shape of the ear remained good and the dermoid cyst has not recurred. This was an interesting case of dermoid cyst that seemed to have caused cryptotia.
