Bottom Line: Skin diseases on the external aspect of the ear are seen in a variety of medical disciplines.Dermatologists, othorhinolaryngologists, general practitioners, general and plastic surgeons are regularly consulted regarding cutaneous lesions on the ear.This article will focus on those diseases wherefore surgery or laser therapy is considered as a possible treatment option or which are potentially subject to surgical evaluation.

Figure 1: Seborrhoic keratosis. Brownish, exophytic tumor with a velvety to finely verrucous surface. Location on the retroauricular site with partial spreading on the helical rim.

Mentions: Seborrhoic keratosis is one of the most common non-malignant tumor of the external ear. It appears as a light brown, mostly flat, sometimes exophytic papular lesion which originates from proliferative epithelial cells (Fig. 1). Its spread increases with age and can potentially affect the whole ear, including the external auditory canal [1]. Ultraviolet light exposure, human papillomavirus infection, hereditary factors, action of oestrogen and other sex hormones are among those factors which have been suggested in the aetiology of this disease [2]. Secondary malignant changes may occur but are extremely rare [3]. Although treatment varies from pure trichloroacetic acid, cryotherapy to electrodessication, we prefer simple curettage or excisional surgery. Since it may be confused with malignant melanoma or squamous cell carcinoma, obtaining a specimen for histology is essential. Histologically this lesion can be devided into seven subtypes: acanthotic; hyperkeratotic; adenoidal or reticulated; clonal; irritated; inverted follicular keratosis; and melanoacanthoma variants [3]. Especially irritated types of seborrhoic keratosis can be misdiagnosed as squamous cell carcinoma as they frequently show active cellular appearances and a downward proliferation of the active epithelial cells. Therefore a sufficient amount of biopsy should be sent for histologic evaluation in cases of macroscopically suspicious lesions which cannot be clearly evaluated as a common seborrhoic keratosis.
