title: A case report of renal pelvic squamous cell carcinoma.
abstract: We describe a case of a 75-year-old woman with squamous cell carcinoma in the right renal pelvis accompanied by multiple dysplasia in the upper urinary tract. Though it is difficult to make a preoperative diagnosis of squamous cell carcinoma, lavage cytology is particularly valuable. Renal arteriography and cross-sectional imaging are also useful to assess an accurate stage. We postulate that severe dysplasia could be a precursor of squamous cell carcinoma as well as transitional cell carcinoma.
