Diffuse astrocytoma is a diffusely infiltrating astrocytoma with a mutation in either the IDH1 or IDH2 gene. Gemistocytic astrocytoma is a variant of IDH-mutant diffuse astrocytoma characterized by the presence of a conspicuous (though variable) proportion of gemistocytic neoplastic astrocytes (gemis...

Methods: Formalin fixed and paraffin embedded tumour samples of 40 consecutive patients with supratentorial diffuse astrocytomas and oligoastrocytomas of WHO grade 2, resected between 1986 and 1993, were used for immunohistochemical staining. The fraction of tumour cells expressing PDGFRα protein was ...

Diffuse pediatric-type high-grade gliomas (pedHGG), H3- and IDH-wildtype, encompass three main DNA-methylation-based subtypes: pedHGG-MYCN, pedHGG-RTK1A/B/C, and pedHGG-RTK2A/B. Since their first description in 2017 tumors of pedHGG-RTK2A/B have not been
