title: [Primary posterior perineal hernia. Case report and review of the literature].
abstract: BACKGROUND
  Perineal hernias may occur after the completion of surgery in this region, or may occur as a primary lesion. Among the less frequent are the perineal hernias.
  
  
  METHODS
  Female patient, 42 years old, with perineal tumor mass on the right of the anus, spontaneously occurring, five years of evolution, with dimensions of 6 × 10 cm, soft and reducible behind transverse perineal muscle. With dignosis of primary posterior perineal hernia, surgery was performed by the perineum with Mersilene mesh placement. There was no recurrence after 18 months follow-up.
  
  
  CONCLUSIONS
  The perineal plasty can be a good alternative for the surgical treatment of primary perineal hernias, as it allows for a better seal, dissect the hernia sac and reduce it properly.
