People who have KTS may have the following features, which can range from mild to more extensive: KTS  Port-wine stain. This pink to reddish-purple birthmark is caused by extra tiny blood vessels (capillaries) in the top layer of skin. The birthmark often covers part of one leg but can involve any portion of the skin. It may get darker or lighter with age. Vein malformations. These include swollen, twisted veins (varicose veins), usually on the surface of the legs. Deeper malformed veins in the arms, legs, abdomen and pelvis also can occur. There may be spongy tissue filled with small veins in or under the skin. Malformed veins may become more prominent with age. Overgrowth of bones and soft tissue. This begins in infancy and may be limited to one leg, but it can occur in an arm or, rarely, in the trunk or face. This overgrowth of bone and tissue creates a larger and longer extremity. Rarely, there may be fusion of fingers or toes or extra fingers or toes. Lymphatic system malformations. The lymphatic system — part of the immune system that protects against infection and disease and transports lymphatic fluid — can be malformed. Extra lymphatic vessels can be present that don't work properly and can lead to fluid leakage into the tissues and swelling. Other conditions. KTS can also include cataracts, glaucoma, hip dislocation at birth, purple-red skin coloring when cold and blood-clotting problems.
