Complete hydatidiform mole coexisting with a live fetus after gamete intrafallopian transfer - A case report

BACKGROUND: Molar pregnancy with a coexisting live fetus is a rare occurren ce. We report the only known case with a surviving coexistent fetus after g amete intrafallopian transfer (GIFT). CASE: After GIFT, a 28-year-old primary infertility patient was diagnosed a s having a complete hydatidiform mole coexisting with a live fetus at 13 we eks of gestation. At 36 weeks of gestation, a cesarean section was performe d due to elevated serum human chorionic gonadotropin (hCG) levels, and a ma le infant with a normal appearance and weighing 2,688 g was delivered. CONCLUSION: If the patient desires to try to carry the fetus to viability a fter counseling on the possible associated risks of malignancy, it is possi ble to achieve fetal viability if (1) there is decline in the serum hCG lev el after it peaks before the second trimester, (2) ultrasound reveals degen eration of the molar part, and (3) there are no complications of pregnancy.
