The pregnancy resulted in a preterm delivery at 30 weeks and 5 days of gestation, with both live fetuses surviving to date. During the pregnancy, the patient was diagnosed with pre-eclampsia and intrahepatic cholestasis. Post-delivery, she was found to have an invasive mole with lung metastases, which was ultimately successfully treated.Conclusion: This report highlights critical considerations for managing a multiple pregnancy complicated by a complete hydatidiform mole, alongside the associated potential complications. In light of the limited literature on the clinical management of this condition, our findings offer valuable insights into navigating the risks and optimizing patient outcomes.Keywords: hydatidiform mole, triplet pregnancy, live fetuses
