A 63-year-old man was admitted to our hospital for a bladder tumor. Drip infusion pyelography, computerized tomography (CT) and magnetic resonance imaging suggested the presence of a large invasive tumor in the right wall of the bladder. Histopathological findings by transurethral resection of bladder tumor showed the presence of sarcomatous and carcinomatous elements. Immunohistochemical examination showed that the sarcomatous component did not stain for S-100 protein or for smooth muscle actin but it stained for epithelial markers. Under the diagnosis of sarcomatoid carcinoma, we performed a total cystectomy and ileal conduit without chemotherapy or radiation. A follow-up CT taken at four months postoperatively showed no evidence of recurrence.
一名63岁男性因膀胱肿瘤入住我院。静脉肾盂造影、计算机断层扫描（CT）和磁共振成像显示膀胱右壁存在一个巨大的浸润性肿瘤。经尿道膀胱肿瘤切除术的组织病理学检查发现存在肉瘤样和癌性成分。免疫组织化学检查显示，肉瘤样成分对S-100蛋白或平滑肌肌动蛋白无染色，但对上皮标志物有染色。在肉瘤样癌的诊断下，我们进行了全膀胱切除术和回肠代膀胱术，未进行化疗或放疗。术后四个月的随访CT显示没有复发迹象。
