Papillary glioneuronal tumors are newly recognized seizure producing tumors. We report two such cases with immunohistochemical characterization of glial and neuronal components and briefly review literature. Co-localization of glial and neuronal markers was demonstrable on confocal microscopy with expression of stem cell markers (Nestin and CD133) suggesting possible origin from neuroepithelial stem cell with biphenotypic differentiation.
