OBJECTIVE: To document a rare case of coexisting endometriosis and mature cystic teratoma in the same ovary. DESIGN: Case report. SETTING: Gynecology unit in a tertiary training and teaching hospital in Cape Town, South Africa. PATIENT(S): A 30-year-old healthy nulligravida woman with a large ovarian tumor. INTERVENTION(S): After a basic examination, a diagnostic and management laparotomy was performed. A unilateral oophorectomy and staging laparotomy were performed. MAIN OUTCOME MEASURE(S): Final diagnosis of a complex ovarian tumor. RESULT(S): Histologic analysis confirmed endometriosis of the pelvis and concomitant compound pathology in the right ovary, which included endometriosis, mature teratoma, and mucinous cystadenoma. CONCLUSION(S): Co-existence of varied pathology in a single organ presents a challenge to the pathologist and the clinician. Accurate clinical (i.e., surgical) assessment and decisive histologic verification forms a critical part in this process. This case of coexisting endometriosis and teratoma in a single ovary is, to our knowledge, only the third case reported in literature.
