Abstract

Several conditions such as nipple eczema, erosive adenomatosis of the nipple, mammary Paget's disease and hyperkeratosis of the nipple and areola occur exclusively in the region of the areola and nipple. Seborrheic keratosis is a benign epidermal lesion that can appear on any part of the body but reported cases appearing on the areola are very rare. Cutaneous horn generally presents as an asymptomatic, conical keratotic mass, which commonly occurs on sun-exposed skin, and has an underlying condition that may be benign, premalignant, or malignant. Seborrheic keratosis is a well known benign underlying condition of the cutaneous horn. We herein present a 49-year-old male with a conical hyperkeratotic mass on his right areola, which, upon microscopic examination was revealed to be seborrheic keratosis.
