ABSTRACT
BACKGROUND: This case describes the youngest patient documented in the literature who presented with a giant hydatidiform mole, effectively addressed through conservative treatment. CASE PRESENTATION: Our department received a 20-year-old Caucasian patient who was admitted due to significant metrorrhagia in an undisclosed pregnancy. During examination, we identified a massive, highly vascularized hydatidiform mole measuring 22 cm (cm). We performed a surgical dilatation and curettage. The anatomopathological findings confirmed the presence of a complete hydatidiform mole (CHM). Following the established guidelines, we conducted weekly monitoring of human chorionic gonadotropin (hCG). Unfortunately, the patient discontinued the follow-up and became pregnant again before achieving hCG negativation. CONCLUSION: This case suggests that conservative treatment is a viable option regardless of the size of gestational trophoblastic disease (GTD), especially when the preservation of fertility is a crucial consideration, as effectively demonstrated in our case.
