What is port wine birthmark?

A port wine birthmark is a red or purple mark that looks like a stain on the skin. These birthmarks can occur anywhere on the body, but are most commonly found on the face. These marks occur when blood vessels, known as capillaries, in the skin are larger because of insufficient nerve supply.
