Primary bladder tumor is a frequent urological malignancy, whereas the incidence of secondary bladder tumor from a distant organ is quite rare. Secondary bladder neoplasms represent 1% of all malignant bladder tumors, of which distant metastases from stomach account for about 4% of cases. We present the case of a 30-year-old male who underwent partial gastrectomy for Signet-ring cell carcinoma of the stomach and presented 2 years later with hematuria. On computerized tomography scan, a bladder tumor was found which was resected cystoscopically. The histopathological examination revealed secondary Signet-ring cell adenocarcinoma of the urinary bladder.
原发性膀胱肿瘤是一种常见的泌尿系统恶性肿瘤，而远处器官继发的膀胱肿瘤发病率相当罕见。继发性膀胱肿瘤占所有恶性膀胱肿瘤的1%，其中胃的远处转移约占病例的4%。我们报告一例30岁男性，因胃印戒细胞癌接受了部分胃切除术，2年后出现血尿。在计算机断层扫描中发现膀胱肿瘤，经膀胱镜切除。组织病理学检查显示为继发性膀胱印戒细胞腺癌。
