Seborrheic Keratosis (SKs) are benign growths that typically appear in mid to later life. They usually will start off as small rough bumps before thickening. They are typically brown or tan in color, although their color can range from black to white. SKs start small and then slowly become thicker and develop a wart-like surface. SKs are not contagious and do not require treatment. Their removal is considered cosmetic and not covered by insurance. Methods of removal include cryosurgery and electrodessication.
