 Port-wine stain
Definition Alternative Names Causes, incidence, and risk factors Symptoms Signs and tests Treatment Support Groups Complications Calling your health care provider References DefinitionA port-wine stain is birthmark in which swollen blood vessels cause a reddish-purplish discoloration of the skin. Alternative Names Nevus flammeus Causes, incidence, and risk factorsPort-wine stains occur in about 3 out of 1,000 people. Port-wine stains may be a sign of Sturge-Weber syndrome or Klippel-Trenaunay-Weber syndrome. SymptomsEarly 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 testsYour doctor can usually diagnose a port wine stain by looking at the skin. In unusual cases, a skin biopsy may be needed. Depending on the location of the birthmark and other symptoms, your doctor may order an intraocular pressure test or x-ray of the skull. TreatmentMany treatments have been tried for port-wine stains, including freezing, surgery, radiation, and tattooing. Laser therapy has been the most successful at destroying stains. It is the only method that can destroy the tiny blood vessels in the skin without significantly damaging the skin. The exact type of laser used depends on the person's age and particular port-wine stain. Support GroupsStains 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. ComplicationsSome stains may occasionally cause deformity and increasing disfigurement. Persons with port-wine stains may have emotional and social problems related to their appearance. Port-wine stains that involve the upper and lower eyelids may be associated with the development of glaucoma. Calling your health care providerAll birthmarks should be evaluated by the health care provider during a routine examination.
