Abstract
|
|
|
|
Seborrheic keratoses are common superficial benign epithelial lesions of the skin. However, sometimes they can develop into malignant lesions including in situ change, basal cell carcinoma or squamous cell carcinoma. These lesions can be located anywhere on the skin, but auricular involvement is extremely rare. We report an unusual case of a large irritated seborrheic keratosis of the auricle, which caused conductive hearing loss by obstructing the external auditory meatus. We also reviewed and discuss the etiology, differential diagnosis and treatment strategy of these benign disfiguring lesions.
