Seborrheic keratoses (SK’s) are benign skin growths that commonly occur on the body and face. Sometimes referred to as “barnacles,” seborrheic keratoses do not have a potential to develop into skin cancer. They are often inherited, but greater numbers of seborrheic keratoses can be found in areas of heavy sun exposure. They appear on the skin as raised, stuck-on tan to very dark brown bumps. Sk’s are sometimes confused for melanoma or atypical moles, as they can have many colors with irregular or raised borders. Liquid nitrogen, shave excision, and laser destruction all can be used to treat seborrheic keratoses.
