腎盂扁平上皮癌の1症例と本邦症例の統計的考察

Abstract

A 33-year-old man was admitted with a chief complaint of flank abdominal on the left side. Preoperative diagnosis was made as solitary renal cyst complicated with two caluculi and pyonephrosis resulting from intracalyceal calculus. Nephrectomy was performed. Pathohistological studies showed squamous cell carcinoma of the renal pelvis. Squamous cell carcinoma of the renal pelvis is relatively rare, and the presense of calculus had been regarded as important in its pathogenesis. Preoperative diagnosis of the disease is, however, usually quite difficult, and five-years survival had not been reported but one. 107 cases of squamous cell carcinoma of the renal pelvis including our case were collected from the Japanese literature.
