Rare case of perplexing ovarian endometriosis
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.
