A port wine stain is usually a large flat patch of purple or dark red skin with well-defined borders. The size of port wine stains is from a few millimeters to many centimeters in diameter. They may occur on the face, trunk or limbs. It occurs in about 0.3% of newborns. These can occur equally among males and females.

It destroys the blood vessels that make up the birthmark without injuring the skin on top. Many treatment sessions are usually needed and it is not always successful.
Australia and other countries to respond to treatment with the flashlamp-pumped dye laser. This treatment is often urgent or semiurgent, depending on the rate of proliferation of the haemangioma or rate of ulceration and tissue destruction. Cosmetic or camouflage creams are often very helpful and expert advice is available in special British Red Cross clinics based at selected dermatology centres.
