Endometriosis is classically defined by the ectopic presence of tissues possessing the morphological and functional characteristics of the endometrium. Ovarian endometriosis is one of the most common locations. Its pathogenesis remains unclear, but a multifactorial origin has been proposed. The symptomatology is dominated by pain and infertility. The clinical examination is often poor. The suprapubic pelvic ultrasound, and especially the endovaginal ultrasound, remains the examination of first intension. Laparoscopy is the only test to affirm with certainty; biopsies, classify it into stages and choose the most appropriate therapeutic strategy. The treatment of the first intension remains surgical, the medical treatments being in the majority of the cases only palliatives. The therapeutic success depends on the radicality of the surgical excision.
