Endometriosis is an estrogen-dependent disorder defined as the deposition and growth of endometrial tissue outside the uterus, including but not limited to the pelvic peritoneum, rectovaginal septum, and ovaries. Endometriosis is a substantial contributor to pelvic pain and subfertility and has been associated with an increased incidence of certain cancers, including ovarian. Appropriate treatment of endometriosis can reduce morbidity, but generally is used only to address symptoms, since no cure currently exists. Multifactorial etiologies for endometriosis have been proposed, with significant evidence for genetic, immune, and environmental causes. Recent advances suggest that molecular signaling and programmed cell death pathways are involved in endometriosis, suggesting avenues for future curative treatments. The goal of this review is to examine the pathologic processes of endometriosis, focusing on cell signaling and cell death pathways, stem cells, treatment regimens, and future directions surrounding this gynecologic disorder.
