Neuroendocrine carcinoma of bladder is a rare malignancy of urinary bladder accounting for 0.35–0.70% of all the bladder carcinoma [1]. These carcinomas develop from epithelium rich in enterochromaffin cells. According to the 2016 World Health Organization Classification of Tumours of Urinary System and Male Genital Organ, neuroendocrine tumors are divided into four subtypes, namely, small cell neuroendocrine carcinoma, large cell neuroendocrine carcinoma, welldifferentiated neuroendocrine tumor, and paragangliomas [2]. Small cell carcinoma of the bladder (SCCB) is a rare, poorly differentiated neuroendocrine epithelial tumor. It is associated with a more aggressive behavior and poorer outcome as compared with urothelial cell carcinoma of bladder. Here, we report a case of pure small cell neuroendocrine carcinoma of bladder in a male patient who underwent first TURBT followed by radical cystoprostatectomy. Case Report
