Introduction: Adenomyosis is defined by the abnormal location of endometrial tissue within the myometrium associated with hypertrophy or hyperplasia of the myometrial stroma. It is a chronic estrogen dependent condition. Although pathogenesis and etiology of adenomyosis remain unknown, two main theories have been proposed: invagination of the endometrial basal layer and metaplasia of embryonic stem cells. Prevalence of adenomyosis varies widely from 5 to 70% with recent studies showing about 20% prevalence among which the majority were premenopausal.
