The amnion is seen at the very top of the image and composed of a simple cuboidal epithelium and a layer of eosinophilic (pink) connective tissue. It has a few scattered neutrophils - which makes the diagnosis of chorioamnionitis. Below the amnion is a cleft and then the chorion, which also has neutrophils.

The fetus (baby) - not shown - would be over the image (and surrounded by amnionic fluid).

The pattern of inflammation seen in this image is typical of chorioamnionitis; most chorioamnionitis results from an ascending infection, i.e. the microorganisms ascend from the vagina/cervix.
