title: Extracranial metastasis of an astrocytoma detected by fine-needle aspiration: a case report.
abstract: Extracranial metastasis of gliomas is rare, and the documented cases of extracranial metastasis are based on histological material. A case of metastatic astrocytoma to the soft tissue of the neck and back detected by fine-needle aspiration is reported. Demonstration of glial fibrillary acidic protein by immunoperoxidase technique on aspirated material helped to confirm the diagnosis.
