Angiosarcoma of the lower leg in chronic lymphoedema.

Sir Angiosarcomas (AS) are rare malignant neoplasms of mesenchymal origin that exhibit vascular di¡erentiation. They mainly a¡ect adult men. They account for approximately 1% of all sarcomas and 35% primarily a¡ect the skin, usually on the head and neck (1). Ten percent of angiosarcomas develop in chronic lymphoedema (2). Some are associated with lymphoedema due to conditions such as trauma, congenital factors, post-surgical lymphatic obstructions, ¢lariosis and idiopathic causes (3).
