PATHOLOGY

The specimen consists of the placentae and membrane, without disease, but showing the lower pole a separate (succenturiate) accessory lobule. Vessels connecting it to the main placenta can be seen crossing the intervening space. Such accessory lobes are due to the persistence of some chronic villi in the chorion laeve.
