Microscopic findings in this placenta were significant for a marginal retroplacental hematoma and overlying villous infarct (consistent with placental abruption) and for diffuse intervillous fibrin and CD68- and CD3-positive mononuclear cell infiltrates, consistent with macrophages and lymphocytes, respectively, and with SARS-CoV-2 placentitis. This evidence concerns the gene CD68 and placental abruption.
