title: Rare Co-existence of Squamous Cell Carcinoma with Infiltration of Renal Vein and Xanthogranulomatous Pyelonephritis.
abstract: Primary renal squamous cell carcinoma is a very rare malignancy of the upper urinary tract. Most patients have history of chronic urolithiasis, analgesics abuse, radiotherapy or infection. Co-existence of SCC with xanthogranulomatous pyelonephritis is exceedingly rare with only few reports in the literature. We report a case of a 60-year-old male presented with right flank pain and mild tenderness of abdomen. Computed tomography of the abdomen revealed gross hydronephrosis with parenchymal thinning and irregular thick enhancing wall of pelvicalyceal system with multiple calculi in right kidney. Right renal vein appeared distended, filled with hypo dense material. Right nephrectomy was performed and sent for pathological examination. Histological evaluation revealed keratinizing squamous cell carcinoma with infiltration of renal vein and xanthogranulomatous pyelonephritis.
