Klippel Trenaunay Weber Syndrome:

Klippel-Trenaunay syndrome is characterized by a triad of port-wine stain, varicose veins, and bony and soft tissue hypertrophy involving an extremity. KTWS generally affects a single extremity, although cases of multiple affected limbs have been reported. The leg is the most common site followed by the arms, the trunk, and rarely the head and the neck. This hemangioma has a distinct, linear border that respects the midline. Hemangioma is often noted on the lateral aspect of the limb.It is typically of the nevus flammeus type, but cavernous hemangiomas or lymphangiomas may also occur. Nevus flammeus is a salmon pink patch, sometimes with a verrucous quality, which evolves to a deep purple color with time. Unlike strawberry hemangiomas, the port-wine stain hemangioma possesses neither a proliferative nor a regressing phase.
