Port Wine Birthmark
About Port-Wine Stains
0 About 3 out of every 1,000 kids are born with a port-wine stain —
a birthmark that literally looks like maroon wine was spilled or
splashed on the skin.
0 Port-wine stains can be anywhere on the body but most
commonly are found on the face, neck, scalp, arms, or legs. They
can be any size, and usually grow in proportion with a child.
0 They often change in texture over time, too — early on, they're
smooth and flat but they may thicken and feel like pebbles under
the skin during adulthood.

Cause Of Port Wine
0 Port-wine stains happen when an area of skin doesn't
get any supply of nerve fibers, which normally help
keep blood vessels narrow.
0 When there's a lack of nerve fibers, small blood vessels
(called capillaries) keep expanding, allowing a greater
amount of blood to flow into the blood vessels, causing
a stain to form under the skin. Birthmarks that form
like this are called vascular birthmarks.
