Nephrotic syndrome at 5 months: no definitive treatment or complications for 12 years.

We describe a patient who developed nephrotic syndrome at 5 months, with extensive glomerular and tubular damage on biopsy. The patient was treated with diuretics and was asymptomatic for a decade despite unremitting proteinuria. A repeat biopsy at 13 years of age showed remarkable healing with histopathological features consistent with "minimal change" nephrotic syndrome. This patient illustrates a favorable clinical outcome, without specific treatment, of nephrotic syndrome of long duration.
