✦ Synopsis

A woman in complete remission from acute myeloblastic leukemia developed thrombotic thrombocytopenic purpura (TTP) subsequent to the third intensive consolidation cycle of cytosine arabinoside and daunorubicin chemotherapy. The constellation of clinical manifestations indicative of TTP were recognized only in retrospect, as they were initially attributed to more usual coinplications of bone marrow-ablative chemotherapy. The manifestations, probably fueled by numerous red cell and platelet transfusions, increased at the time of recovery of hematopoiesis. At postmortem examination, characteristic microvascular lesions were found in most organs. Similar thrombotic microangiopathy has been described with mitomycin-based chemotherapy regimens and with the combination of cisplatin, vinblastine, and bleomycin. Successful management of this serious complication of chemotherapy requires increased awareness and earlier recognition.
