Congenital Palatal Teratoma: A Rare Case of Postnatal Diagnosis and Multidisciplinary Management.

Oropharyngeal teratoma (OPT) is a rare congenital tumor that may present either in isolation or in conjunction with craniofacial anomalies, often posing a major risk to infant survival. Recent advances in prenatal imaging, particularly high-resolution ultrasonography, have significantly improved the early detection and characterization of such tumors, enhancing clinical decision-making. Although prenatal sonography and MRI typically enable early diagnosis, the present study reported a case of OPT, diagnosed postpartum in an Iranian female infant weighing 4300 g. Despite the absence of prenatal diagnosis, the mass was successfully managed through prompt surgical intervention. The outcome was favorable, with no complications or recurrence. This case highlighted the critical role of early diagnosis and multidisciplinary perinatal planning in improving the prognosis of rare congenital tumors such as OPT.
