A Case or Squamous Cell Carcinoma of the Renal Pelvis Associated with Squamous Cell Carcinoma in Situ of the Ureter / 대한비뇨기과학회지

Squamous cell carcinoma of the renal pelvis is relatively rare and its prognosis is very poor. It is believed that the transitional cell epithelium undergoes metaplasia caused by the presence of infection and chronic irritation by renal stone. We observed a case of squamous cell carcinoma of the renal pelvis associated with squamous cell carcinoma in situ of ureter in a 68-year-old female patient. But she had no history of urolithiasis or urinary infection in situ.
