Uterine cervical adenocarcinoma metastasizing concurrently to eutopic and ectopic ovaries: A case report

Ectopic ovary, a designation that includes supernumerary ovaries and accessory ovaries, is a rare gonadal anomaly. We encountered a patient with a metastasis to such an anomaly and herein provide a review of the published work. A 43-year-old woman was diagnosed with stage IIb cervical adenocarcinoma with suspicion for a right ovarian malignancy. She underwent laparotomy after completing three cycles of neoadjuvant chemotherapy. Intraoperative inspection revealed two normal ovaries, but an ovary-like structure was identified attached to the fimbriae of the left fallopian tube. A cystic tumor, 12 cm in diameter, developed from this structure, which was not connected to the infundibulopelvic ligament. The mass was pulled and elevated into the right pelvis by omental adhesions. Pathological examination revealed uterine cervical endometrioid adenocarcinoma with deep stromal invasion, vaginal invasion, and pelvic lymph-node metastases. Both the left eutopic ovary and the ovary-like structure contained endometrioid adenocarcinoma metastases. The ovary-like structure contained spindle-shaped theca cells, which were positive for inhibin α; therefore, this structure was defined as ovarian tissue. The final diagnosis was well-differentiated uterine cervical endometrioid adenocarcinoma with metastases to the pelvic lymph nodes and to the left eutopic and ectopic ovaries (pT2a2N1M0). To the best of our knowledge, there have been no previous descriptions in the English-language published work of uterine cervical adenocarcinoma metastasizing concurrently to unilateral eutopic and ectopic ovaries. © 2016 Japan Society of Obstetrics and Gynecology.
