          Skin ulceration is a well-characterized thrombotic complication of the heparin-induced thrombocytopenia (HIT) syndrome. We present the case of a 73-year-old diabetic woman nearing end-stage renal failure who developed extensive upper thigh, abdominal and buttock ulceration following initiation of subcutaneous heparin for prophylaxis against deep vein thrombosis. A preliminary diagnosis of calciphylaxis was made based on the classical distribution and macroscopic appearance of the ulceration in a patient with end-stage renal failure and secondary hyperparathyroidism. However skin biopsy showed complete absence of calcium deposits in the dermal microvasculature. The presence of extensive microthrombi within dermal vessels prompted serologic testing to detect a prothrombotic state. We identified the combined presence of heparin-dependent platelet activating (HIT) antibodies and functional protein S deficiency. To our knowledge this is the first reported case of a dialysis patient presenting with skin ulceration induced by heparin and protein S deficiency. This case highlights the importance of a skin biopsy and testing for a hypercoaguable state in patients with end-stage renal disease and skin ulceration. We suggest that HIT antibodies should be requested in all dialysis patients presenting with skin ulceration.

          Association of heparin-induced skin lesions, intracutaneous tests, and heparin-induced IgG.

          Cutaneous heparin-induced allergic reactions to subcutaneous heparin may begin 2-5 days after administration. The relation of the delayed-type hypersensitivity and a systemic immunologic response is controversial. The present investigation aimed to analyze the occurrence of thromboembolic complication, pathologic heparin-induced platelet activation (HIPA), and the presence of circulating heparin-induced IgG in patients with heparin-induced skin reactions. Intracutaneous tests, HIPA assay, and heparin-heparin IgG antibodies were performed in nine patients with heparin-induced skin lesions. Six of eight patients showed positive intracutaneous tests to heparin and to four low-molecular-weight heparins. Three of six heparin-positive patients presented hypersensitivity to a heparinoid, too. Two of three patients had a positive HIPA test and elevated heparin-induced IgG antibodies. Both patients developed complications presenting as heparin-induced skin necrosis or arterial thrombosis. Two of nine patients were treated with danaparoid, 4/9 patients received r-hirudin, and 1/9 received oral coumarin. In 2/9 patients, anticoagulant therapy was stopped, but these patients will receive r-hirudin if indicated. On the basis of the coincidence of local and systemic hyperreactivity to heparin and danaparoid, patients with heparin-induced skin lesions should receive r-hirudin, a nonheparin compound, for anticoagulant treatment.

            Recurrent warfarin-induced skin necrosis in kindreds with protein S deficiency.

            Warfarin-induced skin necrosis is a rare complication of anticoagulant treatment. The incidence of this complication is undetermined, but it has been estimated to occur between 1:100 and 1:10,000 of patients treated with anticoagulants. Coumarin skin necrosis occurs almost exclusively in patients with venous thrombosis between the 3rd and 10th day after beginning anticoagulation. Although protein C deficiency is the most common underlying hypercoagulable state reportedly associated with warfarin skin necrosis, very few cases have been linked to congenital protein S deficiency. This article addresses the association of hereditary protein S deficiency and warfarin skin necrosis, and provides suggestions for management.
