Gross and histopathologic descriptions of circummarginate placentas compared with normal membrane placentas is virtually non-existent in pathology literature. We reviewed 50 circummarginate placentas from term pregnancies in the SUH catchment area from 2016-2026 and compared gross and histopathologic findings with 50 placentas with normal membrane insertion. Gross and histologic findings with the greatest difference in prevalence compared with controls included those associated with maternal vascular malperfusion such as increased peri villous fibrin deposition, distal villous hypoplasia, infarction, chronic chorionitis, retroplacental haematoma and villous oedema. Circummarginate placentas did not meaningfully differ from controls regarding prevalence of acute funisitis, acute chorioamnionitis, meconium staining, increased villous capillaries, intervillous thrombi, calcifications or increased syncytial knots. As circummarginate placental membranes are visible on ultrasound beginning at around 20 weeks, increased monitoring of pregnancies from this point may help identify, monitor and/or prevent clinical conditions associated with maternal vascular malperfusion such as pre-eclampsia, gestational diabetes and hypertension, growth restriction and autoimmune diseases/ thrombophilias.
