title: High-grade cerebral neuroblastoma: a case study.
abstract: The case of a 48-year-old male patient is reported in whom a primary malignant cerebral neoplasm was cured by its neurosurgical removal and by postoperative radiotherapy and chemotherapy. Initially, from the results of the examination of frozen and paraffin section, the tumour was considered to be a glioblastoma multiforme. Electronmicroscopy, immunohistochemistry and review of the light microscopy of the original biopsy sample after his death by suicide four-and-a-half years later showed the neoplasm to have been a primary cerebral neuroblastoma rather than a glioblastoma. The diagnosis of glioblastoma multiforme, which depends upon multiple non-specific microscopic findings, such as necrosis, abnormal blood vessels, anaplasia and the pleomorphism of tumour cells, often is imprecise. Our experience underlines the need for comprehensive neuropathological studies of malignant cerebral neoplasms, including transmission electronmicroscopy and immunohistochemistry. This is of particular importance in view of the dismal prognosis of glioblastoma multiforme and of the palliative, rather than curative, treatment programmes that frequently are indicated for this tumour. The value of our report is to demonstrate that a cerebral neuroblastoma, which potentially is curable, may be mistaken easily for a glioblastoma-even by competent neuropathologists.
