title: Arterial thrombosis and protein S deficiency.
abstract: A previously healthy boy had progressive painful discoloration of the lower extremities and was treated with exchange transfusion and anticoagulation, which were unsuccessful in arresting pedal ischemia; amputation of all of the child's toes was required. Studies of the patient and his parents resulted in a diagnosis of inherited protein S deficiency.
