Birthmarks are common. They occur in one out of 10 newborns. One of the most disfiguring types is the vascular birthmark, which is composed of blood vessels in the skin giving it a red or purple appearance. The larger tumor-like birthmarks, called hemangiomas, enlarge during the first few months of life and may cause swelling and distortion of vital structures on the face. Flat discolored patches on the
face, called port wine stains, may be harmless or may be associated with more serious neurological problems. These birthmarks often get darker or rougher in adults.
