title: Ovarian endometrioma in an 11-year-old girl before menarche: a case study with literature review.
abstract: BACKGROUND
  To date, a limited number of endometriosis cases occurring before or around the time of menarche have been documented.
  
  
  METHODS
  An 11-year-old adolescent underwent an emergency operation for left ovarian endometrioma. Her menarche occurred spontaneously 6 months after surgery.
  
  
  CONCLUSIONS
  We discuss the above mentioned case and consider data published in the literature. Endometrioma should be considered even in premenarcheal girls with ovarian cysts, regardless of their size.
