Are port wine stains congenital?
A Port Wine Stain (PWS) birthmark, also called nevus flammeus, is a congenital, cutaneous vascular malformation. It involves post-capillary venules which produce a light pink to red to dark-red- violet discoloration of human skin.
What syndrome is associated with port-wine stain?
Sturge-Weber syndrome is a disease that affects the skin and nervous system (neurocutaneous) and is associated with Port Wine Stain, red vascular markings on the face and other parts of the body (shown here on the legs).

Involvement of the gastrointestinal (GI) tract is uncommon in KTS, but it can be a source of life-threatening bleeding.
What is Klippel-Trenaunay-Weber syndrome?
Klippel-Trenaunay syndrome is a condition that affects the development of blood vessels, soft tissues (such as skin and muscles), and bones.
