Vascular tumours in occlusive disease of the iliac-femoral vessels.

Two cases of intraluminal tumours of the iliac-femoral vessels are presented. One was a benign haemangioendothelioma of the common femoral vein and the other a leiomyosarcoma of the iliac artery. Their clinical features were similar to those of patients having venous thrombosis and atherosclerotic occlusive disease respectively. Consequently every physician specialized in vascular disease should be aware of intraluminal tumours as an uncommon explanation of these common clinical pictures.
