Abstract
-
Primary squamous cell carcinoma of the renal pelvis and ureter is a rare tumor, representing only about 0.7 to 7% of all primary tumors of the upper urinary tract. Their pathogenesis is unclear, but it is assumed to begin with urothelial metaplasia resulting from a reaction to chronic irritation by stone or infection. We report a case of primary squamous cell carcinoma of ureter without stone or infection in 71-year-old male patient.
