The "specific glioneuronal element" of dysembryoplastic neuroepithelial tumor

A "floating neuron" is circled in this "specific glioneuronal element" of a DNT

A pathognomonic feature of dysembrioplastic neuroepithelial tumors (DNTs) is the "specific glioneuronal element" which consists of oligodendroglial-like cells lined up on either side of a paucicellular and mucinous region in which lone neurons appear to float.
