Abstract

Primary squamous cell carcinomas of the renal pelvis and ureter are rare tumors, accounting for less than 1% of all primary tumors of the upper urinary tract. The ratio of renal pelvis to ureter tumors is approximately 6:1. The pathogenesis is assumed to begin with an urothelial metaplasia, as a result of a reaction to chronic irritation and infection, which lead to dysplasia, and ultimately to a squamous cell carcinoma. Only one case of a squamous cell carcinoma of the ureter has been reported in the Korean literature. We report a case of a primary squamous cell carcinoma of the ureter, as a result of a reaction to chronic irritation and infection in a 48-year-old male patient.
