Nongestational ovarian choriocarcinoma with bilateral teratoma: A rare case report and literature review.
Medicine (Baltimore) 2024 May 4
INTRODUCTION: Trophoblastic neoplasms are often associated with pregnancy, and nongestational trophoblastic neoplasms are extremely rare. Nongestational ovarian choriocarcinoma (NGCO) is a highly aggressive germ cell-derived tumor frequently presenting with early hematogenous metastasis.
PATIENT CONCERNS: Herein, we report a case of a 28-year-old unmarried woman with regular menstruation who experienced vaginal bleeding 1 week after her last menstrual cycle. Doppler ultrasound revealed bilateral adnexal masses and elevated serum human chorionic gonadotropin (hCG) levels. The patient was initially misdiagnosed as presenting an ectopic pregnancy.
DIAGNOSIS: The final pathology confirmed an International Federation of Gynecology and Obstetrics stage IA NGCO with bilateral mature teratoma of the ovary. This is an extraordinary instance of ovarian choriocarcinoma which emerged without any prior gestation, and the patient's lack of a history of pregnancy made the diagnosis ignored.
INTERVENTIONS: After initial surgery and 1 cycle of bleomycin, etoposide, and cisplatin (BEP) chemotherapy, a laparoscopic fertility-preserving comprehensive staging surgery was performed. Two cycles of chemotherapy with BEP were administered as supplemental therapy postsurgery, and leuprorelin was administered to protect ovarian function.
OUTCOMES: Menstruation resumed 4 months after chemotherapy completion, and tumor indicators were within the normal range. No signs of recurrence were observed at the 36-month follow-up.
CONCLUSION: NGCO should be considered if a female patient exhibits irregular vaginal bleeding and masses in the adnexal area. The present case and our literature review also highlighted that fertility-sparing surgery and multidrug chemotherapy are effective methods for treating NGCO.
