Thrombotic thrombocytopenic purpura as an etiology of thrombocytopenia in systemic lupus erythematosus: case report.

Abstract Thrombotic thrombocytopenic purpura (TTP) is an unusual complication of systemic lupus erythematosus (SLE). Although the reported association between SLE and TTP is increasing, a few cases do improve without plasmatherapy. We report a case of TTP which was successfully treated without plasmatherapy, which might be underestimated as an etiology of thrombocytopenia in SLE.
