Seborrheic Keratoses
A seborrheic keratosis is a common, noncancerous growth. Seborrheic keratoses usually develop with age and appear as brown, black, or tan, waxy, flat or raised growths, with a characteristic stuck-on appearance. Seborrheic keratoses are benign (harmless) and usually require no treatment. Occasionally they can become itchy, inflamed, bleed, or irritated from catching on clothing and jewelry. They can appear anywhere on the skin and most commonly occur on the face, chest, shoulders, back, and extremities. .
While seborrheic keratoses are benign, it is important to have growths and changes to your skin evaluated by a dermatologist. It can be difficult to distinguish between normal and dangerous growths and it is especially important to have new or changing growths medically evaluated, given seborrheic keratoses can sometimes look like other more medically serious conditions such as malignant melanoma. The decades of combined dermatological and surgical experience at Skin and Laser Dermatology Center will ensure your provider has the expertise to evaluate and manage your skin conditions.

It is not known exactly what causes seborrheic keratoses. They appear to run in some families, so genetics may play a role. There is some evidence to suggest that skin that is exposed to the sun is more likely to develop a seborrheic keratosis, however, they can appear on sun-protected skin.
