Solitary fibrous tumor (SFT) is a rare fibroblast stroma tumor involving the mediastinum and pleura. We herein describe an SFT of bladder which is extremely rare and review 29 similar cases in the last decades. We present a case of a 52-year-old male patient who suffered from urinary urgency and frequency for 12 months. Non-contrast computed tomography (CT) showed a slightly high density calcified mass with 70 mm × 61 mm in diameter. Contrast-enhanced CT demonstrated the mass was slightly enhanced. Cystoscopy revealed a huge mass with flat surface. Histopathological review of the biopsy specimens could not confirm the diagnosis. Partial cystectomy was then performed and the diagnosis of SFT was confirmed by immunohistochemistry. The patient is doing well at 12 months follow-up without recurrence and metastasis. In conclusion, the diagnosis of SFT involving bladder should combine clinical presentation and imaging features. Complete surgical resection is the primary method and long-term follow-up is necessary.
孤立性纤维瘤（SFT）是一种罕见的成纤维细胞性间质肿瘤，可累及纵隔和胸膜。我们在此描述1例极其罕见的膀胱SFT，并回顾过去几十年中29例类似病例。我们报告1例52岁男性患者，其尿急、尿频12个月。平扫计算机断层扫描（CT）显示一个直径70 mm×61 mm的稍高密度钙化肿块。增强CT显示该肿块轻度强化。膀胱镜检查发现一个表面平坦的巨大肿块。活检标本的组织病理学检查未能确诊。随后行膀胱部分切除术，免疫组织化学检查确诊为SFT。患者在12个月的随访中情况良好，无复发和转移。总之，膀胱SFT的诊断应结合临床表现和影像学特征。完整的手术切除是主要治疗方法，长期随访是必要的。
