Also known as Lymphangiosarcoma of Stewart and Treves, Stewart-Treves syndrome (disorder), malignant Lymphangioendothelioma, skin lymphangiosarcoma, Stewart-Treves syndrome, Lymphangiosarcoma of the Skin, Lymphangiosarcoma of Skin

Lymphangiosarcoma is a rare cancer which occurs in long-standing cases of primary or secondary lymphedema (swelling due to lymphatic system obstruction). It involves either the upper or lower lymphedematous extremities but is most common in upper extremities. Although its name implies lymphatic origin, it is believed to arise from endothelial cells and may be more accurately referred to as angiosarcoma.
