title: An unusual cause of adnexal mass: fallopian tube schwannoma.
abstract: BACKGROUND
  Schwannoma is a well-defined, usually benign tumor arising from the Schwann cells in the nerve sheath. It can present in any location as a solitary mass; however, it is rarely found in the pelvis.
  
  
  METHODS
  We report a 40-year-old female patient with a pelvic mass, which revealed tubal schwannoma after complete resection of the mass and uterus by laparotomy.
  
  
  CONCLUSIONS
  Schwannomas are thought to result from a proliferation of perineural cells. Although origin along the nerves of the retroperitoneal space is not uncommon, these tumors rarely present as pelvic masses.
