Gynecologic Oncology

Question:

A 26 year old G2 P1 presents to you at approximately 8 weeks of pregnancy with vaginal bleeding. You find a markedly enlarged uterus with a beta hCG level of 535,000 and ultrasound consistent with a complete hydatidiform mole. The ultrasound examination also reveals bilateral ovarian masses which are multicystic with a complex architecture each measuring 8 cm. You inform the patient that these are most likely:

dermoid cysts
borderline ovarian tumors
evidence of advanced gestational trophoblastic neoplasia
theca lutein ovarian cysts
evidence of an underlying placental-site tumor
