Glomerulocystic kidney disease. Report of an adult case.

A case of glomerulocystic kidney disease (GCK) in an adult is reported. The patient described here had no other congenital malformations, and there was no family history of renal disease. The histopathologic findings support the glomerular origin of GCK. This case illustrated that GCK may be associated with stable renal function for many years. In view of this, GCK should be considered in the differential diagnosis of cystic kidney disease in the adult.
