Seborrheic Keratosis of Auricle: A Case Report and Literature Review / 대한이비인후과학회지

ABSTRACT

Seborrheic keratosis (SK) is a common benign lesion that develops from the proliferation of epidermal cells. Since SK usually occurs on the face, extremities, and upper trunk of the elderly, the finding of this lesion on the auricle is rare. Given the rarity of SK lesions of the auricle and the lack of familiarity with its presentation, otolaryngologists have difficulty diagnosing SK. Authors experienced a case of solitary SK that originated from the auricle in a 65-year-old man. We present this case with a review of the literature.
