Klippel-Trenaunay-Weber syndrome.

The Klippel-Trenaunay-Weber syndrome is characterized by the triad of a port-wine stain, varicose veins, and bony and soft-tissue hypertrophy of an extremity. Recognition is usually possible during infancy or early childhood, and evaluation and treatment is important because morbidity may be minimized. We will review the clinical features, etiology, assessment, and treatment of patients with Klippel-Trenaunay-Weber syndrome.
