[Pathologic changes of the placenta in normal labor].

A total of 73 placentas of at-term newborns with a normal course of pregnancy and delivery were morphologically examined. In 6 of them unexpected extensive changes were evidenced: placentitis in 5 cases (3 suppurative) and the hyaline thrombosis of numerous blood vessels in one case. On the basis of these observations the authors recommend systematic pathohistological examinations of the placenta also in so-called normal deliveries.
