Port-wine stains (PWS) are irregularly shaped birthmarks in which swollen blood vessels create a reddish-purplish discoloration of the skin, looking like someone spilled wine on the skin. Unlike some other birthmarks, such as a “stork bite” or “strawberry,” a port-wine stain grows as the child grows and will last into adulthood. The color usually gets darker, turning purple or a deep red. The skin of a port-wine stain often gets thicker, and it may go from feeling smooth to pebbly.
