title: [Spontaneous bone marrow micrometastasis of a cerebral glioma. Immunohistochemical diagnosis in a biopsy sample and review of the literature].
abstract: A 55 year-old woman was admitted to hospital in January 1981 with transient expressive dysphasia. Past personal history was unremarkable except for a six-month history of renal colic and thrombophlebitis in the veins of the right leg. Computed tomographic scan of the head and carotid angiogram revealed a left calcified temporoparietal tumor. Because of pulmonary embolism it was decided to refute a cerebral biopsy. The patient also declined radiotherapy. In May 1983, a thorough workup revealed an incomplete fracture of the first lumbar vertebra and a diffuse demineralization of the rachis and pelvis. Four weeks later she developed temporal epilepsy and pulmonary embolism. A whole brain irradiation (60 Gy) was performed in August 1983. The patient's condition remained clinically stable until December 1984 when she was readmitted to hospital with a severe weight loss, diffuse osseous pain and pancytopenia. A bone marrow biopsy from the iliac crest showed a diffuse tumor involvement. Peroxidase-antiperoxidase staining using monoclonal antiserum to glial fibrillary acidic protein was strongly positive in numerous tumors cells. The pathological diagnosis was bone marrow metastasis by glioma. She died in March 1985, 4 years and 3 months after the first admission to hospital. Autopsy was not performed. A literature search reveals only 9 cases of extraneural spreading of astrocytomas and glioblastomas in the absence of previous craniotomy with post-mortem examination. The authors also comment on the clinical, pathological and histogenic aspects of extraneural metastasis of gliomas.
