AbstractThe case report of a congenital nasopharyngeal teratoma presented as an intra-amniotic sac mass was described. Histologically, the tumor was composed of highly differentiated tissue derived from three germ layers. Those tissues were partially developed as infant organs with a central core made up by bone. Haphazardly arrangement of such tissues with disorganized sketal axis helped in differentiating the mass from an asymmetric twins. The evidence of tumor attach- ment was seen at the retro-uvular region.
