External auditory canal cholesteatoma is an uncommon otologic entity and its incidence is less than 0.5% of new otologic patients.
External auditory canal cholesteatoma is characterized by an invasion and erosion of squamous epithelial tissue into localized area in bony ear canal. Clinically, it presents as otorrhea and chronic dull pain.
