title: [Diagnosis and surgical treatment of solitary fibrous tumor of the pelvis].
abstract: OBJECTIVE
  To explore the clinical diagnosis and surgical treatment of pelvic solitary fibrous tumor (SFT).
  
  
  METHODS
  The data of nine cases of pelvic solitary fibrous tumor from April 2008 to February 2012 were reviewed retrospectively.
  
  
  RESULTS
  There were 7 male and 2 female patients in this group with a median age of 56 years, of whom 6 were asymptomatic. Their CT showed the tissue density was inhomogencous. Multivisceral resections were performed in 5 patients. Microscopically, the tumor cells were shuttle-shaped, short spindle-shaped or round, and mitoses was rare, immunohistochemistry: CD34, CD99, Bcl-2, Vimentin positive rates were 100%. One patient died 34 months after the surgery, and there was no recurrence in other patients.
  
  
  CONCLUSIONS
  Pelvic SFT is rare. It is difficult to make an accurate diagnosis. Surgery is the most effective therapy. Multivisceral resections are needed sometimes. The prognosis is good for most patients.
