Thrombotic thrombocytopenic purpura in patient with metastatic occult adenocarcinoma. A case report]

In the past two decades, in addition to idiopathic thrombotic thrombocytopenic purpura (TTP) more cases of secondary TTP have been identified, perhaps due to an enthusiasm for cure potential with an availability of exchange-plasmapheresis. An early diagnosis is important, because the evaluation of patients with suspected thrombotic thrombocytopenic purpura is difficult since the diagnostic criteria, thrombocytopenia, microangiopathic haemolytic anemia and no other clinically apparent etiology are not specific.
