Small cell carcinoma of the urinary bladder (SCCB) is a rare and aggressive form of bladder cancer with poor prognosis. Hematuria is the main symptom of this malignancy, and most patients have a history of smoking. The disease incidence of malignant bladder tumors in China is approximately 0.74%. Early and accurate diagnosis of SCCB can ensure timely and appropriate treatment of this malignant disease. Oncologic surgery is the standard treatment; however, it may not be a curative approach. Chemotherapy and/or radiotherapy should be performed following surgical removal. This case report describes a patient with a single neoplasm diagnosed as SCCB that arose because of recurrence of bladder cancer after bladder tumor resection. In contrast to previously reported cases, this patient had no gross hematuria and no history of smoking.
