Will’s Tumor The tumor has taken over the whole Renal’s parenchyma. The original Renal Parenchyma remains like a “coat” surrounding the tumor.

Renal Clear Cell Carcinoma Tumor arise out of Renal tubules. It grows outward on the external surface and compresses the renal parenchyma. This results in a pseudocapsule. Cutsurface shows numerous areas of necrosis. The tumor has a yellow aspect due to adipose tissue. (The clear cells are due to deposition of glycogen and

Chronic Gramulanephritis. It is due to chronic ischemia. The kidney has atrophied, is irregular, and shrunken. Its pale and external surface shows granulity. Cut surface shows a diffuse architecture, which impairs the distinction between cortex and

Chronic Pyelonephritis. It can have a specific cause or a non-specific. Specific causes include Tuberculosis, Sarcoidosis etc. In this case the causative agent Tuberculosis. The large “abscess” is typical for Tuberculosis infection(called a Tuberculoma). There are diffuse areas of caseous necrosis. The
