R132H mutant IDH1 immunohistochemistry in WHO grade II astrocytoma and astrocytosis. Strong granular cytoplasmic mutant IDH1 staining in cellular area of astrocytoma (a H&E; b mutant IDH1) and in infiltrating tumor cells (c H&E; d mutant IDH1); example of two cases, individual mutant IDH1-positive infiltrating tumor cells in cortex (d upper panels, case 18) and at the edge of the tumor (d bottom panel, case 4). Marked astrocytosis adjacent to an infarct positive for GFAP (e) and negative for mutant IDH1 (f). Magnification a–f = 400×; d, upper panels = 1,000×
