Overview

Klippel-Trenaunay (klih-PEL tray-no-NAY) syndrome ? also called KTS ? is a rare disorder found at birth (congenital) involving abnormal development of blood vessels, soft tissues (such as skin and muscles), bones, and the lymphatic system. The main features include a red birthmark (port-wine stain), overgrowth of tissues and bones, and vein malformations with or without lymphatic abnormalities.

Although there is no cure for KTS, the goal is to manage symptoms and prevent complications.
