Histological characteristics of chronic chorioamnionitis (CCA) an inflammation of the fetal membranes (amnion and chorion) due to a bacterial infection.

ICD Code: O41.1 Infection of amniotic sac and membranes Amnionitis Chorioamnionitis Membranitis Placentitis

  • Stage 1
    • a - inflammation showing infiltration of lymphocytes limited to the chorionic trophoblast layer
    • b - CD3 immunostaining demonstrates that the majority of these cells are T cells
  • Stage 2
    • c - inflammation is characterized by infiltration of lymphocytes into the chorioamniotic connective tissue layer (Stain - Haematoxylin Eosin)
    • d - largely CD3+ T cells
