Wilms tumor and nephrotic syndrome in male pseudohermaphroditism.

A case is reported of a child with male pseudohermaphroditism in whom Wilms tumor developed at age twenty-two months. The tumor was treated accordingly, but the child subsequently died of nephrotic syndrome with renal failure at age thirty-two months. After reviewing the similar concurrence of these disorders described as a syndrome, it was suggested that they may have basic embryologic abnormalities in common and that all of them originate during embryogenesis. The importance of bearing this syndrome in mind in the management of a child with abnormal gonadal differentiation is stressed.
