Villous growths in every way identical with those found inthe bladder are sometimes found growing from the pelvis ofthe kidney (Fig. 141). In one very striking case of this sortrecorded by Murchison the pelves of the kidneys of aman 65 years of age were found thus occupied, and asingular feature of the case was the presence of two villous 240 EFITHELIAL TUMOURS tumours in tlie bladder, one at the orifice of each ureter. Itis not improbable, from what we know of the habits of wartsgenerally, that in this exceptional instance the vesical wartswere due to transplantations of epithelium from the pelvis ofthe kidney to the mucous membrane of the bladder. Thepassage of detached villous tufts down the ureter caused. Fig. lil.—Kidney with a villous papilloma growing in its pelvis. colic like a renal calculus in a man in his eightieth year(Lendon). Villous papilloma of the renal pelvis is a somewhat rareaffection, and the subjects are generally past middle life; thecondition is often bilateral, and simulates cancer of thekidnej-. The reported cases have been collected by Nash andSavory. If care be taken to exclude cases of carcinoma of thekidney with villous tufts, true villous disease of the kidneywill be found a rare condition.
