We report a case of undifferentiated small cell carcinoma of the urinary bladder in a 64-year-old male patient. Microscopically the tumor was similar to the intermediate type of small cell carcinoma of the lung, with some foci of transitional papillary carcinoma, adenocarcinoma and carcinoma in situ. Small cell carcinoma is seldom encountered in the urinary bladder. It is more aggressive and must be distinguished from poorly differentiated transitional cell carcinoma.
我们报告一例64岁男性患者的膀胱未分化小细胞癌。显微镜下，肿瘤类似于肺中间型小细胞癌，伴有一些移行乳头状癌、腺癌和原位癌灶。膀胱小细胞癌很少见。它侵袭性更强，必须与低分化移行细胞癌相鉴别。
