Small Cell Carcinoma of the Bladder: A Rare Case

In this case report, we explore a case of small cell bladder carcinoma in a 75-year-old man with a history of smoking. This is a unique, aggressive subtype of bladder cancer which, in this patient, presented with gross hematuria. Workup included cystoscopy and transurethral resection of the bladder tumor, and pathological confirmation of the diagnosis elicited a referral to oncology for staging CT and potential chemotherapeutic measures. While the small cell carcinoma was successfully identified, it had already invaded the detrusor muscle on presentation, prompting the question of how to go about diagnosing and treating this subtype of bladder cancer earlier, which future studies may explore
