Clinicians have long appreciated that there is increased risk of poor pregnancy outcome in women with clinical or subclinical (i.e., serological) evid Acute chorioamnionitis is defined by the presence of acute inflammation (neutrophils) within the chorion or amnion (or both) of the extraplacental membranes or chorionic plate (maternal inflammatory response [MIR]), with or without acute inflammatory cell extravasation from the umbilical cord vasculature or chorionic plate .

This placenta showed prominent lymphohistiocytic villitis and intervillositis and signs of maternal and foetal malperfusion.
The requests for placental pathology are soaring, due partly to demands from obstetricians and to the litigious environment in which they practice, and to improved obstetrical care leading to pregnancies in medically challenging situations. Infectious process characterized by a predominantly leukocytic villous infiltrate, which can be either maternal (usually) or fetal (rarely) in origin. VILLITIS OF UNKNOWN ETIOLOGY Chronic villitis is a relatively common pathologic nding usually in the third trimester placenta and has two distinct clinical associations: infectious and (apparently) non-infectious. Placenta pathology associated with maturation abnormalities and late intra uterine foetal death. Placental villitis seen here is accompanied by a couple of enlarged cells with mauve intranuclear inclusions typical for congenital cytomegalovirus infection.

The fetus is delivered Suspected to be immune-mediated. Placental examination has a critical role in understanding adverse fetal and maternal outcomes in pregnancy. The placenta may be regarded as the "black box" of pregnancy and detailed examination may afford insight into the fetal and maternal events leading to this tragic outcome. Umbilical cord: hematoma single umbilical artery and supernumerary . It is best regarded as a morphological pattern usually seen in association with other pathology (unlike chronic villitis where the villitis is the key feature and the differential usually due to maternal immune reactionVUE or viral infection).

Placental Pathology. Elizabeth Ann L. Enninga, Ph.D., an immunologist at Mayo Clinic's campus in Rochester, Minnesota, is studying villitis of unknown etiology (VUE), a placental condition that is inflammatory, not infectious like cytomegalovirus, Toxoplasma gondii or HIV.Findings from the study were published in The Journal of Immunology in April 2020. 5 Placental examination is a useful adjunct in defining etiology, prognosis, and risk of recurrence of pregnancy disorders, and is aided by the provision by the clinician of pertinent history to guide this .
