Abstract

The designation of "astrocytoma" includes a small subset of tumors with astrocytic differentiation that are lower grade and better circumscribed than the diffuse astrocytomas. These tumors arise in the pediatric population most frequently, but are also occasionally noted in adults and include the pilocytic astrocytoma, pleomorphic xanthoastrocytoma (PXA), and subependymal giant cell astrocytoma (SEGA). Each of these has distinct localizations, histologic appearances, molecular genetic profiles, and natural histories, which is generally more favorable than the diffuse astrocytomas.
