Abstract:
A mother developed multimetastatic gestational choriocarcinoma 13 months after delivery, and her infant died aged 11 months from the same tumor. The transplacental choriocarcinoma transmission was confirmed by genotyping. Henceforth, we recommend a 2-year maternal human chorionic gonadotropin follow-up after neonatal choriocarcinoma and extensive imaging if the human chorionic gonadotropin rises.
