Vascular lesions may be categorized as proliferative tumors, such as hemangiomas, or nonproliferative malformations that include capillary, lymphatic, venous, arterial, or mixed lesions. Lymphatic malformations are benign localized congenital malformations of the lymphatic system. They may be microcystic or macrocystic lesions or a combination of both. The lesions may also be uniseptate or mult...

Vascular anomalies are a diverse group of related conditions that include vascular tumors (hemangiomas) and vascular malformations (capillary malformations, venous malformations, lymphatic malformations and arteriovenous malformations). In the past decade or so, research has revealed the genetic or molecular basis for some of these lesions. We now know that a number of hereditary vascular malfo...

Lymphatic malformations (LMs) are rare congenital vascular malformations. Lymphatic malformations include a wide variety of diseases, such as lymphangiomatosis, macro or microcystic lymphatic malformation, and lymphangiectasia. Lymphatic malformations are often first seen at birth, although intrauterine diagnosis is not uncommon. Depending on their size and location, they can be asymptomatic or...

Klippel-Trenaunay syndrome (KTS) is a rare complex malformation characterized by the clinical triad of capillary malformations, soft tissue and bone hypertrophy, and venous/lymphatic malformation. Fractures of long bones in such cases are challenging to treat. A 12-year-old female with this syndrome presented with femoral shaft fracture of right thigh. She was initially kept on skeletal tractio...
