A case of sebaceous hyperplasia mimicking keloid in external ear

Sebaceous hyperplasia, a common, benign condition of sebaceous gland, presents most commonly over face but rare in the ear canal. Lesions on the face are usually described as asymptomatic, soft, discrete, and yellow with a surface that ranges from smooth to slightly verrucous. The pathogenesis is not fully understood. It does not require treatment, but many time lesions can be cosmetically unfavorable than, need to be destroyed or excised. We experienced a case of a 61-year-old female, presented with a rubbery mass on the canal side of her right tragus. Based on her past history, a keloid following previous tympanoplasty was suggested and surgical removal was done. Final pathologic diagnosis was a sebaceous hyperplasia over the right external ear.
