Thrombotic thrombocytopenic purpura (TTP) is characterized by the pentad of fever, thrombocytopenia, microangiopathic hemolytic anemia, fluctuating neurologic symptoms, and renal dysfunction. Thrombotic thrombocytopenic purpura has recently been reported in association with rheumatic diseases (RDs). ⋯ It is important to identify TTP as a cause of thrombocytopenia and hemolysis when occurring in patients with RDs since management, treatment, and prognosis differ. Early recognition and prompt institution of plasmapheresis may improve the outcome in patients with TTP.
