Figure 2

(a) Cords and nests of tumor cells are surrounded by dense fibrotic stroma and adipose tissue; hematoxylin-eosin, original magnification ×40. (b) The meningothelial cells are spindly looking with pink cytoplasm. Cells are packed together forming syncytial structures and whorls; hematoxylin-eosin, original magnification ×200. (c) Tumor cells show strong and diffuse cytoplasmic staining with vimentin (magnification ×100), (d) weak to moderate cytoplasmic and nuclear staining with S-100 (magnification ×100), and (e) focal weak to moderate nuclear staining with progesterone receptor (PR) (magnification ×100).
