title: Adenosarcoma in a patient with vaginal endometriosis.
abstract: BACKGROUND
  Adenosarcoma in a patient with extraovarian endometriosis is a rare event and can be easily overlooked.
  
  
  METHODS
  A woman with a history of endometriosis underwent multiple resections of a vaginal mass and medical treatment for presumed recurrent endometriosis. Eventually, a vaginal adenosarcoma was diagnosed.
  
  
  CONCLUSIONS
  The possibility of adenosarcoma should be considered if an enlarging mass occurs at the site of extraovarian endometriosis.
