Small cell carcinoma of the urinary bladder is a poorly differentiated, aggressive neoplasm [1, 2, 3] that accounts for less than 1% of all bladder tumors. [4]  Men are affected more than women, typically in the the seventh to eighth decades, and hematuria is the most common presenting symptom. [5]

All small cell carcinomas of the urinary system identified thus far have been located in the urinary bladder, most commonly in the dome and vesical lateral wall. [6]  There is no established standard treatment modality for this neoplasm, and outcomes are generally poor. [4, 7, 8]
