Seborrheic keratosis is a condition that causes wart-like growths on the skin. The growths are noncancerous (benign).
Seborrheic keratosis is a benign form of skin tumor. The cause is unknown.
The condition commonly appears after age 40. It tends to run in families.
Symptoms are skin growths that:
Your health care provider will look at the growths to determine if you have the condition. You may need a skin biopsy to confirm the diagnosis.
You usually do not need treatment unless growths get irritated or affect your appearance.
Growths may be removed with surgery or freezing (cryotherapy).
Removing the growths is simple and usually does not cause scars. You may have patches of lighter skin where growths on the trunk have been removed.
Growths usually do not return after they are removed. You may develop more growths in the future if you are prone to the condition.
Call your health care provider if you have symptoms of seborrheic keratosis.
