Nephropathy associated with Wilms' tumor. A case of a 13-year-old girl

The association of nephropathy with Wilms' tumor and male pseudohermaphroditism is known as Drash's syndrome. The absence of either pseudohermaphroditism or Wilms' tumor has also been reported. The nephropathy, characterized by proteinuria or nephrotic syndrome, leads rapidly and inevitably to renal failure. The renal findings are those of a chronic glomerulopathy with mesangial hypercellularity, glomerular sclerosis, interstitial infiltration and marked tubular dilation. This infrequent syndrome usually appears in early life, between 1 and 3 years of age. The case of nephropathy associated with Wilms' tumor we present here is characterized by age and onset: an abrupt onset of renal insufficiency without previous signs of nephropathy in a 13-year-old girl.
