PI.17.g5 Xanthomatous meningioma (MT x100). Pleomorphic cells (multinucleate or with prominent nuclear atypia) disseminated in the tumour, especially near the regions containing foam cells. Cellular pleomorphism as such has no prognostic value unless accompanied by signs of rapid growth (hypercellularity, hyperchromasia, high mitotic index, sometimes necrosis).
