Klippel-Trenaunay-Weber Syndrome Center

Klippel-Trènaunay-Weber (KTW) syndrome is a condition characterized by:

  • port-wine stains or birthmark malformations in the skin,
  • soft tissue and bony growths (generally involving a limb), and
  • vascular anomalies (varicose veins).

Although these three symptoms are consistently found in patients with Klippel-Trènaunay-Weber syndrome, there are other symptoms, which include

  • atrophy (a limb that is underdeveloped),
  • fingers and toes that are disproportionately large or small,
  • digits that are webbed (syndactyly),
  • too many digits (polydactyly), or
  • too few digits (oligodactyly).

The cause of Klippel-Trènaunay-Weber syndrome is not known. However, recently there have been some cases that run in families. There is no significant treatment for Klippel-Trènaunay-Weber syndrome.
