A port-wine stain (nevus flammeus) is a discoloration of the human skin caused by a vascular anomaly (a capillary malformation in the skin).[1] They are so named for their coloration, which is similar in color to port wine, a fortified red wine from Portugal.
A port-wine stain is a capillary malformation, seen at birth.[2] Port-wine stains persist throughout life.[3] The area of skin affected grows in proportion to general growth.
Port-wine stains occur most often on the face but can appear anywhere on the body, particularly on the neck, upper trunk, arms and legs.[2][4] Early stains are usually flat and pink in appearance. As the child matures, the color may deepen to a dark red or purplish color.[2] In adulthood, thickening of the lesion or the development of small lumps may occur.[2][5]
Port-wine stains may be part of a syndrome such as Sturge–Weber syndrome or Klippel–Trénaunay–Weber syndrome.[2]
