A Rare Case of Squamous Cell Carcinoma of Kidney in a Patient with Renal Calculus and Pyonephrosis

Primary squamous cell carcinoma of the renal pelvis is extremely rare with only a few cases reported in the literature. Long standing renal calculus is a known risk factor. We present a case of an elderly male who had bilateral renal calculi and presented with right-sided pyonephrosis which was managed initially by percutaneous nephrostomy and later right nephrectomy was done. The histopathological report stated squamous cell carcinoma of the pelvis with capsular and fat involvement.
