Extracranial oral cavity metastasis from glioblastoma multiforme: A case report

Abstract

� 2016, Spandidos Publications. All rights reserved. Glioblastoma multiforme is the most common primary malignant brain tumor. The clinical outcome following diagnosis remains extremely poor. The treatment of choice is wide surgical resection of the visible tumor, frequently followed by adjuvant combined radiochemotherapy (RCTx) with temozolomide as the chemotherapeutic agent. Extracranial metastases are extremely rare, with < 200 cases of extracranial metastases from glioblastoma multiforme reported in the literature to date. We herein present a case of a patient suffering from a fast-growing metastasis to the oral cavity, completely filling the buccal cavity within 2 weeks, as the only manifestation of recurrent glioblastoma multiforme following initial surgical resection and adjuvant RCTx.
