Adult (autosomal dominant) polycystic kidney disease (ADPKD).

The kidney is enlarged and heavy. Sectioned surface shows loss of demarcation between cortex and medulla and replacement of the entire renal parenchyma by cyst s varying in diameter from a few millimeters to 4-5 cm. These cysts are not communicating with the pelvicalyceal system. The renal pelvis and calyces are distorted due to cystic change.
