Heterotopic brain of the tongue.
A 6-week-old male infant with lingual mass suffered from feeding difficulty and respiratory distress. Resected specimens revealed brain tissue composed of astroglia, oligodendroglia, ependyma, choroid plexus, neuronal cells, and primitive cells but no other elements suggestive of teratoma, therefore it was diagnosed as heterotopic brain of the tongue.
