Expanding the spectrum of the Perlman syndrome.

We report on an infant with manifestations of Perlman syndrome including polyhydramnios, macrosomia, bilateral nephromegaly with nephroblastomatosis, visceromegaly and cryptorchidism. Other findings in this infant not seen in previous patients were diaphragmatic hernia, interrupted aortic arch, hypospadias and polysplenia. This infant meets the diagnostic criteria for Perlman syndrome, suggesting that diaphragmatic hernia and cardiac defects may be additional findings in this disorder.
