A Chronic general tuberculosis is not uncommon in children, in the form of yellow masses, usually softened in the central parts. This is associated with tuberculosis in other parts, usually in the lungs. In adults, phthisis pulmonalis is frequently associated with a few tubercles in the kidneys as well as in the liver, but they are of comparatively small size.
In Acute general tuberculosis there are numerous tubercles in the kidneys, mostly in the cortex. They are usually elongated in shape and visible to the naked eye as small pale areas. Under the microscope they are found to be caseous in their central parts while peripherally their cells infiltrate between the tubules.
