Postoperative spindle cell nodule (PSCN) of the bladder is a rare condition. It is a type of benign lesion frequently misdiagnosed as sarcomatoid carcinoma on the basis of similar cell morphology. The present report describes a tumor affecting a 71-year-old male who had undergone three transurethral resections. Pathological results suggested a diagnosis of sarcomatoid carcinoma, and therefore a radical cystectomy was performed. However, the tumor was later identified as a PSCN. In order to prevent such misdiagnosis, this study reviews relevant articles concerning postoperative spindle cell nodules of the bladder and compares PSCN and sarcomatoid carcinomas to identify specific characteristics of PSCN. Finally, the report emphasizes the importance of careful pathological examination in rare cases such as PSCN and sarcomatoid carcinoma.
膀胱术后梭形细胞结节（PSCN）是一种罕见病症。它是一种良性病变，常因细胞形态相似而被误诊为肉瘤样癌。本报告描述了一例影响一名71岁男性的肿瘤，该男性已接受了三次经尿道切除术。病理结果提示诊断为肉瘤样癌，因此进行了根治性膀胱切除术。然而，该肿瘤后来被确定为PSCN。为防止此类误诊，本研究回顾了有关膀胱术后梭形细胞结节的相关文章，并比较了PSCN和肉瘤样癌以确定PSCN的具体特征。最后，该报告强调了在PSCN和肉瘤样癌等罕见病例中进行仔细病理检查的重要性。
