Acute ischaemia of the lower limb: an unusual presenting feature of acute lymphoblastic leukaemia.

Malignant disease is often complicated by coagulation disorders presenting as abnormal clotting or bleeding, acute leukaemia being more often associated with the latter. Acute lymphoblastic leukaemia presenting with peripheral arterial thromboembolism, previously unreported in the literature, is presented. Aetiology, clinical features, and management of coagulation disturbances associated with malignancy are also reviewed.
