title: Bone metastases from secondary glioblastoma multiforme: a case report.
abstract: Extraneural metastases of glioblastoma multiforme (GBM) are a relatively rare occurrence which usually manifest after de novo GBM. We report a case of a patient with an oligodendroastrocytoma who developed over a period of 12 years malignant progression to glioblastoma followed by multiple cytologically confirmed bone metastases. No 1p deletions were detected in the original tumour. GBM cells disclosed the EGFr(+) and p53(-) immunophenotype more characteristic of a primary GBM.
