title: Case report: dermal inclusion cyst of the external auditory canal.
abstract: Dermal inclusion cysts are benign masses that arise as the result of the entrapment of ectodermal components during embryogenesis. Their presenting symptoms are a direct result of the mass effect of the growing cyst. We describe the case of a 23-month-old girl who presented with a single, large dermal inclusion cyst in the external auditory canal. Our review of the literature revealed that only 2 other cases of a dermal inclusion cyst in this location have been previously reported.
