| pubmed-article:3165517 | pubmed:abstractText | A polypoid tumor containing astrocytic glia and ependyma was excised from the base of the tongue of a 3-month-old infant. Neuroid elements were identified immunocytochemically and by means of electron microscopy. We attribute this rare anomaly to displacement of brain tissue in early embryogenesis before closure of the palate. | lld:pubmed |
