Renal Calculus Complicated with Squamous Cell Carcinoma of Renal Pelvic: Report of Two Cases

Abstract

Squamous cell carcinoma (SCC) of the renal pelvis is an uncommon tumor, which is usually associated with infection and long standing renal calculus. The neoplasm is highly aggressive, so it is at advanced stage and has a poor outcome when diagnosed. We present two cases who had diseases of kidney stone complicated with mass of renal pelvis. Both patients were operated with radical nephrectomy subsequently. The histopathology report showed that the tumors of renal pelvis were SCC. When come across a case of chronic renal calculi, we should pay attention to whether it exists neoplasm because the co-existing latent mass may bring about misdiagnosing and effect the patient’s treatment plan and prognosis.
