Hydatidiform mole is also known as what?

• A. Gestational trophoblastic disease
• B. Placental previa
• C. Ectopic pregnancy
• D. Ovarian cyst

Answer: (A)

Gestational trophoblastic disease encompasses molar pregnancies, including hydatidiform mole. Hydatidiform mole is a form of GTD, arising from abnormal fertilization and proliferation of placental trophoblast tissue. That broad category also includes other related trophoblastic tumors, whereas the other options—placental previa, ectopic pregnancy, and ovarian cyst—are unrelated placental or gynecologic conditions. So the term that correctly names hydatidiform mole is gestational trophoblastic disease.
