File:IPLab5PolycysticKidney4.jpg|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. File:IPLab5PolycysticKidney5.jpg|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. File:IPLab5PolycysticKidney6.jpg|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. File:IPLab5PolycysticKidney7.jpg|This high-power photomicrograph shows abnormal glomeruli (arrows) and some tubules. File:IPLab5PolycysticKidney8.jpg|This is a gross photograph of the liver from this patient. Multiple cysts can be seen on the surface of this liver (arrows). File:IPLab5PolycysticKidney9.jpg|This photomicrograph of liver demonstrates the histologic appearance of these cysts. File:IPLab5PolycysticKidney10.jpg|This is another photomicrograph of liver demonstrating the histologic appearance of these cysts. These cystic structures are associated with the biliary tree. File:IPLab5PolycysticKidney11.jpg|This is a higher-power photomicrograph of liver cyst. These cystic structures are lined by biliary epithelium.
