Background: Remaining the placenta and membranes is one of the risk factors for postpartum bleeding and puerperal infection. It is valuable to get familiar with the anatomy of the placenta and identify its variants to manage postpartum bleeding and puerperal infections caused by the remaining placenta and membranes. The placenta comprises three main parts: a placental disc, a three-vessel umbilical cord, and two extraplacental membranes (amnion and chorion). An amnion is a thin membrane lacking blood vessels and nerves that includes the chorionic plate and, its vessels and the fetus. There is no report on a placenta with two attached amniotic membranes in singleton pregnancy.
Case Report: This paper reports a placenta related to a baby boy from a singleton pregnancy with three fetal membranes (two attached amniotic layers and a chorionic layer).
Conclusion: In the clinical examination of the placenta, it is important to be aware of the variant of the membranes so that we can prevent possible bleeding and infection after delivery due to the retention of pregnancy products. There is also no report on the variant of membranes, so possible consequences are unknown.
