ABSTRACT
Background: The coexistence of a hydatidiform mole and a fetus can occur in a multiple pregnancy, being less frequent in triplets and quadruplets because of their infrequency. With assisted reproduction, multiple pregnancies are becoming more frequent, and we can expect more frequent coexistence with a molar pregnancy. Case report: This G3, P1 30-year-old mother, after assisted conception, was diagnosed with a quadruplet pregnancy, one of which was a molar conceptus. Due to the potential for malignancy, the pregnancy was electively terminated. Conclusion: Despite the difficulty in conceiving, elective termination of a multiple pregnancy associated with a molar pregnancy may be the most judicious course of action to protect the mother's life.
