The 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 attachment was seen at the retro-uvular region.
本文描述了一例先天性鼻咽畸胎瘤，表现为羊膜囊内肿物。组织学上，肿瘤由源自三个胚层的高度分化组织组成。这些组织部分发育为婴儿器官，中央核心由骨构成。此类组织的随意排列以及骨骼轴紊乱有助于将该肿物与不对称双胎相鉴别。在悬雍垂后区域可见肿瘤附着的证据。
