A rare case of pure small cell carcinoma of urinary bladder
Bladder cancer is the second most common urologic malignancy. Up to 95% of the urinary bladder tumors are of epithelial origin, from which 90% are transitional neoplasms. However, small cell carcinoma of the urinary bladder is rare tumor accounting for<0.7% of bladder cancer, of which the pure form is extremely rare. A 53‑year‑old female presented to urosurgery outpatient department complaining of hematuria and burning micturition since 3 months. Ultrsonography showed a large heteroechoic mass filling whole of the bladder. Histopathological examination of the transurethral debulked tumor mass revealed small cell carcinoma, which was confirmed on immunohistochemistry. We report this case due to its rarity and to add on to literature.
