Chorionic Plate Chronic Inflammatory Lesions Including Eosinophilic/T-Cell Chorionic Vasculitis

  • Philip J. Katzman


The chorionic plate is a placental structure that serves as a barrier between the amnionic sac and the maternal intervillous space of the placenta. Inflammatory cells, including lymphocytes, neutrophils, histiocytes and eosinophils, can be present within the chorionic plate as part of reactive processes that occur during pregnancy.
