Endometriosis in a postmenopausal woman without previous hormonal therapy: a case report

INTRODUCTION: 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. CASE PRESENTATION: 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. CONCLUSION: 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.
