A seborrheic keratosis is a noncancerous skin lesion that appears most commonly on the face, chest, shoulders and back.
A seborrheic keratosis is a benign, or noncancerous, skin lesion that appears as a waxy brown, black or tan wart-like growth. Seborrheic keratoses are amongst the most common noncancerous growths in older adults.
Seborrheic keratoses are most common on the face, chest, shoulders and back. The cause is unknown, although genetics may be involved. They are very common, and generally increase in number with age.
While seborrheic keratoses can look like skin cancers, they are noncancerous and do not require treatment. If they become irritated, or you do not like the appearance of them, they can be removed by a dermatologist. See your dermatologist if many growths appear over time, if the lesions become irritated, or if the lesions grow rapidly or bleed.
