Successful administration of low molecular weight heparin in a patient with heparin-induced thrombocytopenia and coumarin-induced skin necrosis.

A case of heparin-induced thrombocytopenia and skin necrosis induced by coumarin is reported in a 58-year-old female patient suffering from metastatic breast adenocarcinoma and deep vein thrombosis. The thrombosis resolved after treatment with low molecular weight heparin and the thrombocytopenia recovered within a few days. The occurrence of both these rare complications in the same patient has not been previously reported in the literature. We present a review of these complications and their current treatment.
