Nasopharyngeal teratoma as a respiratory emergency in the neonate

We report a congenital nasopharyngeal teratoma which presented as acute neonatal airway obstruction. After immediate orotracheal intubation, a pedunculated mass, which filled the nasopharyngeal and oropharyngeal cavities, was completely removed. Histological examination of the specimen revealed as a mature teratoma, composed of all three germ layers with recognizable early organ differentiation.
