In tj^pical examplesthese organs are converted into cystic masses, so that theyexhibit a sponge-like appearance on section. The cysts varygreatly in size; some are as small as rape-seeds, others aslarge as cherries ; they rarely exceed these dimensions. Someof the cysts project from the surface of the kidney, but, thoughinterfering with the smoothness of the gland, they do notdistort it.

In the early stages the cyst-walls have a membranapropria, and are lined with tesselated epithelium. In ad-vanced stages of the disease and in the large cysts the epi-thelium
