<unk>  is a disease characterized by the presence of functional endometrial tissue outside the uterine cavity. The most commonly affected sites are the ovaries, broad ligaments, and the surrounding pelvic structures.<unk>  can also affect distant sites such as the lungs, ureters, and CNS. The exact pathogenesis of<unk>  has not been established, although several theories have been put forth. The Sampson theory of retrograde menstruation, the coelomic metaplasia theory, and the lymphatic and vascular dissemination theory offer possible explanations for the mechanisms of implantation and invasion of endometrial tissue outside the uterine cavity.<unk>  is a cause of dysmenorrhea and dyspareunia; accordingly, it must be differentiated from other conditions presenting with similar symptoms such as adenomyosis, pelvic inflammatory disease, pelvic congestion syndrome, and submucosal uterine fibroids. The goal of medical therapy is pain management and the reduction of the endometrial implant size. Therapeutic options include GnRH agonists and danazol. Surgical therapy is reserved for patients with severe forms of the disease or who fail to improve with standard medical therapy.
