Papillary glioneuronal tumor-a rare entity: report of four cases and brief review of literature

Agarwal S et al. – Papillary glioneuronal tumors (PGNT) are rare CNS neoplasms. Despite showing focal morphological features reminiscent of oligodendroglial tumors and presence of astrocytic component, they usually lack the common genetic alterations involved in the pathogenesis of gliomas. Multi–institutional pooling of cases may aid in elucidating their oncogenetic pathway.
