Abstract

Seborrheic keratosis lesions are tumors that rarely occur in the external auditory canal. There are several histological variants, and one of them is the irritated seborrheic keratosis. This kind has been scarcely reported in the literature. We report a 62 years old man with this lesion that relapses after monopolar electrocautery, and finally is removed by skin flap dissection.

Keywords: External Auditory Canal; Keratosis; Skin.

A) (Hematoxylin-eosin) In the sample, some horn cysts (circle) and hyperkeratosis are shown. These elements appear in seborrheic keratosis. B) (Hematoxylin-eosin) Few squamous eddies (arrow) with numerous inflammatory cells and many necrotic keratinocytes near the basal cell layer. These facts are characteristic of irritated seborrheic keratosis
