Seborrheic keratosis is a noncancerous skin growth that commonly affects the elderly. Its exact causes are unknown, although it tends to be hereditary. Seborrheic keratosis is a painless condition that requires no treatment; many individuals, however, choose to have the growth(s) removed for cosmetic purposes.

A seborrheic keratosis typically appears on the head, neck, or trunk. It is usually round or oval shaped, and it may vary in color. In some cases, seborrheic keratosis may itch. Medical attention may be necessary if numerous seborrheic keratoses develop in a short period of time, the seborrheic keratoses interfere with clothing, or other abnormal skin changes occur.

Seborrheic keratosis is diagnosed by inspecting the affected area. A biopsy may be taken to rule out skin cancer. Seborrheic keratoses require no treatment. If removal is requested for cosmetic purposes, it may be achieved through cryosurgery, curettage, or electrocautery.
