Notes:
Summary Hemorrhagic skin necrosis of the toes was observed in a patient with heterozygous protein C deficiency (protein C:Ag 32% and protein C activity 30%) on the 4th day of coumarin treatment overlapping with effective intravenous anticoagulation with heparin. Family studies revealed protein C deficiency in two sisters of the proposita without a history of thromboembolic disease. Immunologic studies in the proposita at the time of coumarin necrosis revealed slight depression of complement factor C4 and the presence of immune complexes. The present case and review of the literature show that the pathogenetic mechanism leading to coumarin necrosis in patients with protein C deficiency seems not yet to be fully understood.
