Klippel-Trenaunay-Weber syndrome is a rare congenital syndrome, consisting of vascular malformation of blood and lymph vessels. This disease is characterized by a classic triad of cutaneous hemangiomas, varicose veins, and bone or soft tissue hypertrophy causing limb asymmetry. Clinical presentation may vary from being asymptomatic to developing potentially life-threatening complications, such as deep vein thrombosis (DVT), pulmonary embolism (PE), and recurrent bleeding. Most cases arise from sporadic mutations in one or more genes involved in early embryonic angiogenesis.
