Syphilitic placentitis: demonstration of Treponema pallidum by immunoperoxidase staining
1Department of Neonatology, Kanagawa Children's Medical Center, Yokohama-city, Japan.
We report a case of early congenital syphilis in which the placenta showed diffuse proliferative villitis and Treponema pallidum was identified by indirect immunoperoxidase stain in formalin-fixed paraffin-embedded placental tissue. This is the first report demonstrating T. pallidum in placental tissue using an immunohistochemical method.
