ABSTRACT
These cases fall into two groups. There are those in whom the whole pregnancy has died, leaving a hardened mass of solid tissue, which is often adherent to the wall of the uterus. In the past, this has been known as a carneous mole. There are also those in which the fetus has died and been absorbed or where no fetus developed; in such cases, the placenta and membranes are normal and there is a cavity containing amniotic fluid. This is often known as a blighted ovum.
