Squamous cell carcinoma of the kidney is a rare malignancy of the upper urothelium usually seen at advanced stage due to delay in diagnosis and or presentation. Mostly seen in patients with history of untreated chronic urolithiasis, chronic renal infection or analgesic abuse. A 46-years-old man who presented with right recurrent loin pain that radiates to the right groin of 10 years duration which worsened 2 weeks prior to presentation, he had history of recent haematuria, right loin pain, significant weight lost with associated history of untreated right renal calculi. General examination was not remarkable, ultrasound scan revealed a huge right renal mass with calculi. Intravenous urogram showed a non-functioning right kidney. Right radical nephrectomy was done, cut surface showed replacement of the renal parenchyma with greyish white tumour with stones in some blind calyxes. Histology revealed moderately differentiated squamous cell carcinoma of the right kidney. We report a case of moderately differentiated squamous cell carcinoma of the right kidney in a patient with a long history of untreated renal calculi. High index of suspicion for malignancy should be kept when seeing patients with long history of untreated renal calculi.
