title: [Solitary fibrous tumor of the urinary bladder].
abstract: BACKGROUND
  A solitary fibrous tumor is a rare circumscribed neoplasm that was long known in the pleura and has now described in many organs and soft tissues. Prognosis is favorable after complete excision.
  
  
  METHODS
  We report a solitary tumor fibrous located in the bladder of a 38-year-old man with dysuria and a palpable abdominal mass.
  
  
  CONCLUSIONS
  Solitary fibrous tumors are reported very rarely in the urinary bladder. They may mimic other nonepithelial tumors in this site. Diagnosis based only on pathological features is difficult. When complete excision is possible, prognosis is generally good. Outcome is more serious in approximately 10-20% of cases, and strict follow-up is required.
