is a discoloration of the human skin caused by a capillary malformation in the skin. They are so named for their coloration, which is similar in color to port wine, a red wine from Portugal. Portwine stain is a capillary malformation, seen at birth. Portwine stain persist throughout life. The area of skin affected grows in proportion to general growth.
Portwine stain occur most often on the face but can appear anywhere on the body, particularly on the neck, upper trunk, arms and legs. Early stains are usually flat and pink in appearance. As the child matures, the color may deepen to a dark red or purplish color. In adulthood, thickening of the lesion or the development of small lumps may occur.
Vascular lasers are somewhat effective, but require expensive laser equipment and long-term treatment over several years. As lesions thicken with age, laser treatment may become less effective, which can be a problem. Pink lesions are generally more difficult to treat than red lesions because they are deeply vascularized.
