[Aggressive therapy in a case of Moschowitz syndrome]

We report a case of thrombotic thrombocytopenic purpura which responded spectacularly to therapy consisting of corticosteroids, prostacyclin, high doses of platelet anti-aggregants and repeated plasma exchange. There was no anomaly of the von Willebrand factor VIII. The number of schizocytes and the lactate dehydrogenase level are as important as the beta-thromboglobulin dosage.
