title: Malignant astrocytoma containing bone.
abstract: A case of a malignant cerebral astrocytoma containing bone in a 56-year old woman is reported. In spite of total removal and radiotherapy the tumour recurred and the patient died 18 months postoperatively. The histological features and immunohistochemical findings are presented. The literature is reviewed and probable mechanisms by which these mesodermal derivatives develop in neuroepithelial neoplasms are discussed.
