It is a disc shaped reddish brown structure that connects the fetus to the mother through the umbilical cord. The umbilical cord contains two umbilical arteries and one umbilical vein 2020-10-29 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. To assess the incidence, diagnosis, pathogenesis, and clinical and placental associations of congenital cytomegalovirus infection, 34 cases thereof diagnosed by placental/fetal or neonatal workup (group 1), and 494 placentas with villitis of unknown etiology (group 2) were extracted from a 6083-case placental database. 28 clinical and 47 placental phenotypes were compared between the two groups by Yates 2 … Placental involvement by CMV infection has been typically made by histological diagnosis of focal segmental lymphoplasmacytic villitis [28, 29], with additional histological features as described above and depicted in Fig. 1, and confirmed by positive immunohistochemistry or in situ hybridization on placental tissue [4, 5, 6, 17] (Figs.

This is a condition called villitis, which is usually benign but can increase the risk of fetal death. Villitis of Unknown Etiology (VUE) is a type of inflammation of the placental villi, which occurs due to unknown reasons. In most cases, the inflammation occurs in a term placenta.

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 OF UNKNOWN ETIOLOGY Chronic villitis is a relatively common pathologic ﬁnding usually in the third trimester placenta and has two distinct clinical associations: infectious and (apparently) non-infectious. Villitis of unknown eti-ology (VUE) is a diagnosis of exclusion, requiring ﬁrst that infectious causes be ruled out adequately 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 2021-02-24 · Villitis of unknown etiology (VUE) is an important pattern of placental injury occurring predominantly in term placentas.
An explanation for the rarity of chronic villitis in early preterm pregnancies may be related to the immaturity of placental
Chronic villitis was diagnosed as an infiltrate of lymphocytes and macrophages in the placental villi.
Not surprisingly, little is known about placental ﬁndings in such cases, with only 1 report of 3 cases in the world Villitis of unknown etiology (VUE) is a common lesion affecting placenta mostly during the third trimester on microscopic examination, whatever the pregnancy outcomes is. The cellular composition of the inflammatory infiltrate is defined by lymphocytes and macrophages, and VUE is thought to be the result of an immunological materno-fetal conflict. Clinical and histological characteristics are 2020-12-05 · Placenta Creta Decidua is deficient or absent, at least focally. Villi come into direct contact with myometrium.

The placenta is a unique organ, given that it resides at the interface between two human beings – the mother and the fetus. Additionally, it changes throughout gestation in such a dynamic way that identifying the normal histology can be a challenge in and of itself. This article summarizes the most common pathologic changes in the placenta, devoting the greatest amount of information to the 2020-12-05 Paraffin-embedded placentas from four males with VUE and two males with syphilitic villitis were subjected to fluorescence in situ hybridization (FISH) for the X and Y chromosomes.
