It can cause fetal death at term by fetomaternal hemorrhage. We present a case of intraplacental choriocarcinoma. After a hydatidiform mole with persistence of throphoblastic disease, the patient delivered a stillborn baby at term. Massive fetomaternal hemorrhage was the unexpected cause of death. Choriocarcinoma was only diagnosed after pathologic revision of the placenta because of persistent high levels of serum hCG (human chorionic gonadotropin). Massive fetomaternal hemorrhage should alert the obstetrician and the pathologist to the possibility of choriocarcinoma arising from the placenta
