title: [Peri-testicular fibromatosis (testicular fibrous pseudotumor)].
abstract: OBJECTIVE
  We report a case of fibromatous periorchitis, a rare entity that may have differential diagnosis problems with other lesions.
  
  
  METHODS
  Our patient underwent a surgical procedure with resection of the tunica vaginalis testis after intraoperative histological evaluation.
  
  
  RESULTS
  Findings observed in both intraoperative biopsy and specimen histopathological study were key for diagnosis.
  
  
  CONCLUSIONS
  Although macroscopic appearance of the lesion can be of great value, fibromatous periorchitis diagnosis is based on the histologic features, being important to avoid erroneous therapeutic decisions.
