Abstract
We report an unusual case of fully developed fetal intestinal segment(s) within a nodule on the chorionic plate of the placenta of a 27-year-old female patient at 37 weeks gestation with spontaneous vaginal delivery. Gross examination of the placenta revealed a chorionic plate nodule near the insertion of the umbilical cord, which, upon microscopic evaluation, raised the differential diagnostic possibilities of placental teratoma, vitelline/omphalomesenteric duct anomaly, and intestinal organoid differentiation. We discuss the distinguishing features, morphogenesis, and clinical significance of the aforementioned entities and review the pertinent medical literature.
