Seborrheic keratoses are raised skin growths that look scaly or warty. They usually look like they were stuck onto the skin. They most often grow in groups on the back or chest and are more common in older people. A seborrheic keratosis can be tan or dark brown. A seborrheic keratosis is not a mole and is almost always harmless. But it is still a good idea to check your skin regularly.
Sometimes a seborrheic keratosis can itch. Scratching it can cause it to bleed and sometimes even scar.
A seborrheic keratosis is removed only if it bothers you. The doctor will freeze it or scrape it off with a tool. The doctor can also use a laser to remove a seborrheic keratosis. Treatment usually results in normal-looking skin, but it can leave a light or dark mark or even a scar on the skin.
