Proposed development of low-grade endometrioid and clear cell carcinoma. Endometrial tissue, by a process of retrograde menstruation, implants on the ovarian surface to form an endometriotic cyst from which a low-grade endometrioid or clear cell carcinoma can develop. EMC: low-grade endometrioid carcinoma of the ovary; CCC: clear cell carcinoma of the ovary.
