In acute COVID-19, prominent lymphohistiocytic villitis may occur and might potentially be attributable to SARS-CoV-2 infection of the placenta. Furthermore, there are histopathological signs of maternal and foetal malperfusion, which might have a relationship to an altered coagulative or microangiopathic state induced by SARS-CoV-2, yet this cannot be proven considering a plethora of confounding factors.

Villitis of unknown etiology (VUE), also known as chronic villitis, is a placental injury. VUE is an inflammatory condition involving the chorionic villi (placental villi). VUE is a recurrent condition and can be associated with intrauterine growth restriction (IUGR).

Even if the classic intranuclear and intracytoplasmic inclusions are not seen, an immunohistochemical study for CMV can be beneficial, as it will highlight infected cells and eosinophilic debris within the villi.

Villitis was studied in placentas from 445 singleton infants from an ethnically homogeneous population with a good socioeconomic standard. There were 161 infants small for gestational age (SGA) and

VUE is a recurrent condition and can be associated with intrauterine growth restriction (IUGR). Acute Villitis of Placenta is a bacterial infection of the chorionic villi The placenta is an organ that connects the developing fetus to the uterine wall. It is a disc shaped reddish brown structure that connects the fetus to the mother through the umbilical cord.

VUE is also characterised by the transfer of maternal lymphocytes across the placenta. VUE is diagnosed in 7–10% placentas in pregnancies. Roughly 80% of the VUE cases are in term placentas (greater than 37 weeks of pregnancy).

However, the inciting factors and mechanisms by which VUE contributes to adverse outcomes are poorly understood. The placentas of patients with influenza infection were examined for histologic signs of chronic villitis. In case of villitis, polymerase chain reaction (PCR) on influenza virus was performed on placental tissue.

Villitis of unknown etiology (VUE) is an important pattern of placental injury occurring predominantly in term placentas. Although overlapping with infectious villitis, its clinical and histologic characteristics are distinct. It is a common lesion, affecting 5% to 15% of all placentas. When low-gra …
