ABSTRACT
Fetomaternal hemorrhage induced by intraplacental choriocarcinoma is considered to
be extremely rare. We herein describe a neonate with severe anemia caused by intraplacental
choriocarcinoma that was histopathologically identified after birth. Furthermore,
we reviewed three other such cases in Japan. As a result, the incidence of intraplacental
choriocarcinoma may be higher than previously estimated. Therefore, we suggest that
the placenta should be examined in any suspected cases of fetomaternal hemorrhage.
