We report the case of a 39\u2010year\u2010old pregnant patient with a reactive enzyme immunoassay (EIA) at delivery, despite prior nonreactive syphilis serologies and a negative confirmatory test postpartum. Placental examination revealed multiple intervillous abscesses and chronic villitis, raising concern for congenital syphilis. However, immunohistochemistry (IHC) for\n                    <jats:italic>Treponema pallidum<\/jats:italic>\n                    yielded conflicting results across laboratories. Despite the lack of confirmed maternal infection, the neonate underwent a full congenital syphilis evaluation and received penicillin treatment. This case highlights the complexities of interpreting isolated positive treponemal tests, the limitations of placental pathology in syphilis diagnosis, and the need for standardized management algorithms to prevent misclassification, overtreatment, and undue emotional and healthcare burden. Interdisciplinary communication and rapid confirmatory testing are critical to optimizing maternal and neonatal outcomes.\n
