A Case of a Rare Malignant Mixed Ovarian Germ Cell Tumor Masquerading as an Ectopic Pregnancy

Malignant ovarian germ cell tumors (MOGCTs) are rare but disproportionately affect young women and adolescent girls. Although clinical presentation varies, these tumors can present with an adnexal mass and raised serum beta-human chorionic gonadotrophin (beta-hCG), mimicking an ectopic pregnancy. We present the case of a 20-year-old nulliparous woman, who was initially treated both medically and surgically as an ectopic pregnancy, and was eventually diagnosed with a malignant mixed germ cell tumor (MMGCT) following laparoscopy. We highlight the diagnostic challenges of ectopic pregnancies versus MOGCTs, and the importance of adopting a fertility-sparing approach in young nulliparous women.
