Dialysis-associated acquired cystic kidney disease imitating autosomal dominant polycystic kidney disease in a patient receiving long-term peritoneal dialysis

The typical histological features of epithelial hyperplasia in the cysts, the lack of any family history of renal disease (such as in ADPKD), the fact that there was no cystic transformation in the previously removed right kidney and the lack of extrarenal signs of other genetic cystic disease (such as hepatic cysts or tuberous sclerosis) led to the final diagnosis of ACKD. Patients with end-stage renal failure receiving long-term dialysis treatment occasionally develop very large cystic kidneys imitating ADPKD.
