Excerpt
Papillary glioneuronal tumors (PGNTs) are rare neoplasms affecting young adults, that usually are characterized by an indolent clinical behavior. They are often cystic and arise in the temporal lobe or in the periventricular white matter. Histologically, PGNTs are described in the revised WHO classification (2007) as a biphasic neoplasm characterized by papillary or pseudo-papillary architecture, formed by glial cells and an intervening neuronal component with cells ranging from neurocytes to ganglion cells [
4]. Information regarding their molecular features is relatively limited [
4]. In this report, we describe for the first time the presence of a N546K mutation of
FGFR1 gene in a PGNT arising in the frontal lobe. …
