A rare case of leiomyosarcoma arising from a femoral vein tributary: a case report

Abstract

Abstract Primary vascular tumours are very rare. Most cases are leiomyosarcomas usually arising from large veins such as the inferior vena cava. Involvement of major veins in the limbs is uncommon and of small veins or tributaries extremely uncommon. We report a case of leiomyosarcoma originating from a tributary of the femoral vein in a 55-year-old woman.
