Abstract
Three specimens of surgically removed tuberculous kidney with localized major lesions and with large “normal” areas of the renal parenchyma were examined by the serial section method, with the following results:
1. In the normal renal parenchyma, that is, all the parts except the renal lobe having the main lesion, there were found 58 isolated tubercles in Case 1, 10 in Case 2, and three in Case 3. Many of these tubercles were epithelioid cell tubercles or giant cell tubercles, in no cases was a proliferation of connective tissue fibers observed.
2. A proliferation of connective tissue fibers or scarring was seen at the central areas of the third and fourth conglomerate lesions in Case 1, but tuberculous granulation was detected in their surroundings.
