Capillary malformation - a flat, pink, red, or purple mark that appears at birth and typically covers a large area of the affected limb. Capillary malformations do not go away and continue to grow along with the child. Usually tiny lymphatic vesicles arise in stained areas
• lymphatic abnormalities- cysts, swelling

• Venous anomalies- dilated superficial veins
• Excessive growth of one or more limbs. KTS usually involve a lower limb. This can also invilve the thorax and upper limb, it never invovles the face.

Difference in size between the affected and non-affected limb can also cause problems. Leg length discrepancies may require a procedure to interrupt the growth plate.

In rare cases, patients with KTS may require amputation when the limb is grotesquely enlarged or disfigured.

Patients should be evaluated by members of an experienced interdisciplinary vascular anomalies team. No single specialist can manage KTS and its associated problems, as interventional techniques and surgical procedures are often needed.

Treatment of the symptoms is the most effective therapy. These treatments may include:

• Compression garments (worn on the affected limb) to reduce pain and swelling
• Operation to correct uneven limb growth
• Sclerotherapy to shrink abnormal veins
• Operation to remove problematic veins
• Operation to debulk excessive tissue
