title: Malignancy-associated membranoproliferative glomerulonephritis.
abstract: An 11-year-old girl with an abdominal desmoplastic round cell tumor, treated with chemotherapy, presented with gross hematuria and proteinuria. Renal biopsy revealed type I membranoproliferative glomerulonephritis (MPGN). The association of a malignant tumor and MPGN is extremely unusual in children, and the pathogenesis of the renal lesion under these circumstances is unknown.
