  This is a gross photograph of the kidneys from this case. Note that both kidneys contain multiple large cysts (arrows).

• 

  This is a gross photograph of one of the kidneys from this case next to a normal kidney. This photograph demonstrates how big these polycystic kidneys are compared to a normal kidney.

• 

  This is a gross photograph of a cut section from one of these polycystic kidneys. Note that the renal parenchyma is almost completely replaced by cystic structures.

• 

  This is a low-power photomicrograph of an H&E-stained section from this polycystic kidney. Note the large cystic structures (1), the few residual glomeruli (2), and the fibrous connective tissue throughout this section.

• 

  This is another low-power photomicrograph of an H&E-stained section from this polycystic kidney. Again note the large cystic structures (arrows)and the fibrous connective tissue throughout this section.

• 

  This is a higher-power photomicrograph of polycystic kidney showing the edge of a large cyst (1). In this section there are numerous tubules and dilated collecting ducts (2) that are filled with the same red proteinaceous material as the larger cysts.

• 

  This high-power photomicrograph shows abnormal glomeruli (arrows) and some tubules.

• 

  This is a gross photograph of the liver from this patient. Multiple cysts can be seen on the surface of this liver (arrows).

• 

  This photomicrograph of liver demonstrates the histologic appearance of these cysts.

• 

  This is another photomicrograph of liver demonstrating the histologic appearance of these cysts. These cystic structures are associated with the biliary tree.

• 

  This is a higher-power photomicrograph of liver cyst. These cystic structures are lined by biliary epithelium.
