Primary Squamous Cell Carcinoma of Renal Pelvis Associated with Staghorn Calculi Masquerading as Xanthogranulomatous Pyelonephritis

Abstract

Primary squamous cell carcinoma of renal pelvis is a rare tumour associated with long standing renal calculi. We report here a case in which patient presented with pain abdomen and renal calculus with left pelvi ureteric junction obstruction and final diagnosis of primary squamous cell carcinoma of kidney was made only on histopathological examination. This case has been reported to highlight the silent and unusual presentation of common tumour at an uncommon site. Hence, a high degree of suspicion of squamous cell carcinoma should be made and considered as a differential diagnosis in patients presenting with history of renal stones.
