Which tumor has a mixed neuronal-glial component?

Explanation:
Tumors with mixed neuronal and glial components are glioneuronal tumors. This family uniquely contains both neuronal elements and glial elements within the same neoplasm—for example, ganglioglioma and dysembryoplastic neuroepithelial tumor—so histology shows dysplastic or mature neurons alongside neoplastic glial cells. Immunostains often reveal neuronal markers in the neuronal parts (like synaptophysin) and glial markers (like GFAP) in the glial parts. In contrast, glioblastoma is a highly malignant glial tumor driven by astroglial differentiation, oligodendroglioma is a glial tumor with oligodendroglial features, and ependymoma arises from ependymal cells. So the presence of both neuronal and glial components points to glioneuronal tumors.
