What is a port wine stain?

Also known as: PWS

A port wine stain or PWS is one of the more common birthmarks related to blood vessel growth. Present at birth, an early PWS is usually flat and pink in appearance with the color possibly deepening to a dark red or purplish color as the child gets older. The PWS most common occur on the face but may appear anywhere on the body.
