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. 1 and 2).

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.

In case of villitis, polymerase chain reaction (PCR) on influenza virus was performed on placental tissue. RESULTS: 29 patients had influenza infection. Placentas of 15 of these patients were collected and examined. villitis include lymphohistiocytic, lymphocytic, lympho-plasmocytic lesions, and granulomatous inﬂammation with multinucleate giant cells [1–5] (Fig. 1).

Additionally, the inflammation may spread to the chorionic villi, which cover the placenta and facilitate the exchange of nutrients and gases between the mother and baby.

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). A case of VUE in a placenta less than 32 weeks old should be screened for infectious villitis. The placentas of patients with influenza infection were examined for histologic signs of chronic villitis.
