Epidermal inclusion cyst of external auditory canal.
Epidermal inclusion cyst is a benign cyst filled with keratin fibers, and its wall has nearly the same characteristics as the epidermis. It is commonly seen in the skin and has the tendency to slowly grow toward deeper epidermis parts and to cause cystic expansion. We report a 23-year-old woman who presented with right external otitis lasting for 2 months. The patient's complaints did not respond to treatment even after parenteral antibiotic therapy. Surgical exploration revealed epidermal inclusion cyst of the ear canal. This pathologic entity is discussed in the light of current literature.
