Samll cell carcinoma of the urinary bladder is a rare tumor which occurs in about 0.48% of all bladder tumors. We report cytologic features of small cell carcinoma of the urinary bladder in a 66-year-old man who had painless total gross hematuria, which was confirmed by partial cystectomy. In urine cytology, abundant tumor cells appeared in scattered and clustered forms in a bloody background. The tumor cells were small and uniform in size with a high nuclear/cytoplasmic ratio. The nuclei of the tumor cells were hyperchromatic, characteristically molded and showed inconspicuous nucleoli. The cytoplasms were scanty and plae blue.
Key Words: Small cell carcinoma; Urine cytology; Urineary bladder
