Dermoid cysts of the nose: review of 21 cases

Twenty-one cases of histologically confirmed dermoid cysts of the nose are reviewed. The sites involved were the dorsum (18), septum (5), glabella (2), nasal tip (2), and columella (1), with several patients having multiple sites of involvement. Bony or cartilaginous destruction occurred in 14 patients (67%). A sinus tract was evident in ten patients (48%). Complete excision of these lesions is necessary for prevention of recurrence. The differential diagnosis includes hemangiomas, gliomas, encephaloceles, epidermoid cysts, neurofibromas, and lipomas.
