A Case of Seborrheic Keratosis Developing on the Scapha of the Ear Auricle / 대한피부과학회지

ABSTRACT

Seborrheic keratoses are the most common benign epidermal tumor of the skin and a frequent focus of patient concern because of their variable appearance. Seborrheic keratoses may arise on any non-mucosal surface, including the face, scalp, and trunk. However, it rarely occurs on the ear, especially on the scapha. We report a case of a 42 year-old female patient presenting with 1 cm, brownish pedunculated nodule of seborrheic keratosis on the scapha.
