Papillary glioneuronal tumor of the frontal lobe.
Glioneuronal tumors of the central nervous system (CNS) comprise a group of generally low-grade tumors expressing glial and neuronal cells of varying differentiation. Papillary glioneuronal tumor (PGNT) is a new tumor identified in the World Health Organization's classification of CNS tumors (2007). We report a patient with PGNT and highlight the diagnostic features, including a description of "spidery" astrocytes.
