Seborrheic keratosis (SKs) are common skin growths. These benign (non-cancerous) growths can occur almost anywhere on the skin. Some people can get just one; others develop many. It is easy to mistake an SK for another common skin growth such as a wart or mole. Most SKs begin as a small, rough bump on the skin which tends to grow slowly, gradually thickening and often looks like a wart. An SK can be flat or raised.
What to Expect
Removal of SKs is an easily performed treatment. It is commonly removed with cryosurgery, using extremely cold liquid nitrogen to freeze the SK, causing it to fall off within days. You may see a small dark or light spot on the skin where you had the SK, which usually fades with time. A permanent white spot is a possible side effect of this treatment.
