title: [Paratesticular solitary fibrous tumor].
abstract: OBJECTIVE
  To describe an additional case of paratesticular solitary fibrous tumor.
  
  
  RESULTS
  A 67-year-old man presented a paratesticular mass lasting for one year. Histological examination showed a well-circumscribed lesion comprised of spindle cells proliferation without atypia, arranged in a fascicular pattern, intimately intertwining with thick collagen fibers. Tumor cells were strongly positive for vimentine and CD-34. Diagnostic criteria, clinical features and treatment of this condition are discussed.
  
  
  CONCLUSIONS
  Solitary fibrous tumors are spindle cell neoplasm originally described in the pleura, but may occur in many different sites. Intrascrotal solitary fibrous tumors are uncommon and few cases have been reported.
