Renal Pelvis Squamous Cell Carcinoma and Renal Cell Carcinoma in a Tuberculous Kidney

Squamous cell carcinoma of the renal pelvis.

Primary squamous cell carcinoma (SCC) of the renal pelvis is rare because SCC represents only 0.5% to 0.8% of malignant renal tumors. Chronic irritation, inflammation, and infection induce squamous metaplasia of the renal collecting system, which may progress to dysplasia and carcinoma in most of affected individuals. Nephrolithiasis, especially formation of staghorn calculi, is the most common...

Classical and eosinophilic types are the two histological variants recorded. Also, it has been described in association with carcinoma of collecting ducts, conventional renal cell carcinoma and sarcomatoid renal cel...
