Figure 3: Recurrent tumor: gross photograph (A) and photomicrograph (B: H and E, x20) of dural-based tumor with areas of hemorrhage. Focal whorl formation (C: H and E, x100) with meningothelial cell clusters (C inset: H and E, x200) diagnostic for meningioma. However, majority of the areas showed PAS-positive glycogenated polygonal cells with abundant clear cytoplasm and round, uniform, bland nuclei (D: H and E, x100; E: x200; F: PAS). Cells were immunoreactive to the epithelial membrane antigen (G: x200) and vimentin (H: x200), and the MIB-1- labeling index was low (I: x200)
