Keratinizing desquamative squamous metaplasia (KDSM) of the upper urinary tract is a rare condition. We present a case of a 45-year-old male smoker of more than 20 years presenting with a 1-month history of recurrent, intermittent left fank pain of moderate intensity associated with dysuria and nausea. In this case the differential diagnosis included renal cell carcinoma, tuberculosis of the kidney, and KDSM. However, the pathological fndings showed squamous cell carcinoma arising in KDSM. Hence we report this rare association of a squamous cell carcinoma of the renal pelvis arising in KDSM.
