Seborrheic keratoses are benign skin growths that most people develop as they age. They can appear on any part of the body but are most common on the trunk. They typically appear in adulthood, usually in one’s 30’s or 40’s and are seen in men and women of all races. They are slow growing and their cause is unknown. It is uncommon to have just one SK; one usually has multiple SKs develop over his/her lifetime.
Seborrheic keratoses appear as tan, brown or even black waxy wart-like growths. They are usually round or oval and look like they have been stuck or pasted on to the skin. They have been described as resembling warts or barnacles but sometimes they can resemble a mole. They range in size from millimeters to centimeters and can sometimes be quite itchy and inflamed.
There is no medical need to treat a seborrheic keratosis unless it is symptomatic and causing discomfort either because it is very itchy or inflamed. However, some people find SK’s unattractive and choose to have them removed for cosmetic reasons. They can be removed with liquid nitrogen or shaved off with a curette or a scalpel.
