title: Endometriosis in a postmenopausal woman without previous hormonal therapy: a case report.
abstract: BACKGROUND
  The prevalence of pelvic endometriosis is high, affecting approximately 6% to 10% of women of reproductive age. Although endometriosis has been associated with the occurrence of menstrual cycles, it can affect between 2% to 5% of postmenopausal women.
  
  
  METHODS
  We present a case of ovarian endometriosis in a 62-year-old Spanish Caucasian woman with no previous use of hormonal therapy and no history of endometriosis or infertility.
  
  
  CONCLUSIONS
  ALTHOUGH THE REPORTED SITUATION IS RARE, IT IS IMPORTANT TO BE AWARE OF ENDOMETRIOSIS AFTER THE MENOPAUSE: post-menopausal endometriosis confers a risk of recurrence and malignant transformation.
