title: Recurrent hemolytic uremic syndrome and metastatic malignancy.
abstract: A 64-year-old patient with a prostatic adenocarcinoma presented two well-documented episodes of hemolytic-uremic syndrome (HUS) occurring 8 months apart and resolving without renal sequelae. The temporal relationship between these episodes and the natural progression of the underlying disease as well as the absence of chemotherapy favor the hypothesis of cancer-associated HUS. The clinical, laboratory and pathological findings of this patient and 3 additional patients reported in the literature are discussed. These cases suggest that malignancy should be suspected in adults developing the HUS and that this form of HUS need not have a poor prognosis despite progressive cancer.
