COMMENT The presence of mitotic ﬁgures in this tumor, in the absence of vascular proliferation and necrosis, warrants a diagnosis of a WHO grade III tumor. A well-recognized variant of astrocytoma is marked by prominent numbers of gemistocytes. Gemistocytes are characterized by abundant eosinophilic cytoplasm and eccentrically placed, slightly irregularly shaped nuclei. Perivascular chronic inﬂammatory cells, in particular lymphocytes, may be focally present in these tumors. It is well recognized that astrocytic tumors with a signiﬁcant gemistocytic component tend to behave in a more aggressive fashion, although the WHO still recognizes these lesions as grade II neoplasms.
OPINION Histologic sections show a markedly cellular neoplasm, characterized by a proliferation of atypical-appearing cells resembling malignant astrocytes. 1 Low magniﬁcation appearance, highlighting a glioblastomatous-appearing region of the tumor with necrosis. 2 The glioblastomatous component is juxtaposed to a spindle-cell component in the gliosarcoma. 3 High magniﬁcation, showing glioblastomatous component with necrosis. Frontal and Parietal Lobes, Subtotal Resection— Gliosarcoma, WHO Grade IV.
Case 15: Gliomatosis Cerebri C L I N I C A L I N F O R M AT I O N We consider the lesion to be an astrocytoma and characterize it as follows: Right Frontal Lobe and Corpus Callosum, Biopsies—Gliomatosis Cerebri, WHO Grade III. The patient is a 42-year-old male who presents with seizures and increased lethargy. On MRI imaging, bilateral, multilobe, increased signal intensity is observed on T2-weighted images. Two biopsies, one from the right frontal and the other from the corpus callosum, are taken, and histologic sections are reviewed.
