Final Diagnosis:
Brain, left frontal: Astrocytoma grade 4/4 (glioblastoma multiforme) using the Daumas-Duport grading system.
Microscopic Description:
Sectionsshow the specimen to consist predominantly of necrotic tissue, in areascontaining viable glioma that is high grade. The tumor cells displaysmall cell morphologic characteristics, possible oligodendroglialfeatures, and astrocytic elements with a fibrillar appearance. Mitoticfigures are identified. Vascular proliferation is observed, includingglomeruloid aggregates proliferating capillaries. As previouslymentioned, tumor necrosis is extensive. Abnormally large ectaticvascular structures are also seen, and are consistent with a vascularmalformation. Several vessels are thrombosed.
