Congenital nephrotic syndrome-a treatable cause.

A 27-day-old infant from a tribal area presented with congenital nephrotic syndrome (CNS). The presence of clinical features of syphilis, proven syphilis in the mother and complete recovery following penicillin therapy confirmed a diagnosis of congenital syphilis. In developing countries, treatable causes of CNS such as syphilis need to be considered in infants presenting with nephrotic syndrome.
