Objective: To investigate the clinical diagnosis and treatment characteristics as well as the prognosis of solitary fibrous tumor (SFT) of the urinary bladder, and help clinicians improve the diagnosis and treatment skills.

Methods: We present the clinical data of a patient with SFT of the urinary bladder after 78 months of follow-up and review related literatures. A 46-year-old male patient presented with the main clinical manifestations of progressive dysuresia, total gross hematuria and shock. B ultrasound and computerized tomography (CT) scan revealed a substantive mass within the bladder. Then, cystoscope showed a smooth, sessile, solid tumor covered by normal mucosa, with great vessels on the surface.

Results: The patient underwent open resection of the tumor. Pathologic examination showed a SFT of the bladder, and revealed the expression of CD34 and Bcl-2 protein by immunohistochemical staining test. After 78 months of follow-up, the patient was free of diseases, without any recurrence or other treatment.

Conclusion: The diagnosis of SFT of the urinary bladder can be confirmed by pathological examination of the tumor. The tumor cells were characteristically positive for CD34 and Bcl-2. The prognosis of SFT in the bladder is favorable and partial cystectomy is sufficient, instead of radical cystectomy.
