The following case is reported because it represents from a clinical and pathologic standpoint the various stages in the development of a squamous cell carcinoma of the renal pelvis. Reports of similar cases, although not frequent, illustrate the important relation of irritation1to leukoplakia, and of continued irritation to consequent carcinomatous changes. Kutmann1areported a case of leukoplakia in the renal pelvis, and stated that only 67 similar unquestioned cases had been reported.
