Seborrheic Keratosis

What is a seborrheic keratosis?

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.

What causes seborrheic keratoses?

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.

How can I treat seborrheic keratoses?

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.
