Definition of Port-wine stain
A port-wine stain is a birthmark in which swollen blood vessels create a reddish-purplish discoloration of the skin.
Causes, incidence, and risk factors
Port-wine stains occur in about 3 out of 1,000 people.
Early port-wine stains are usually flat and pink in appearance. As the child gets older, the color may deepen to a dark red or purplish color. They occur most often on the face but can appear anywhere on the body.
Signs and tests
Your doctor can usually diagnose a port wine stain by looking at the skin.
Many treatments have been tried for port-wine stains, including freezing, surgery, radiation, and tattooing.
Stains on the face respond better to laser therapy than those on the arms, legs, or middle of the body. Older stains may be more difficult to treat.
