Giant-celled glioblastoma of brain. A clinico-pathological and radiological study of ten cases (including immunohistochemistry and ultrastructure)

Giant-celled glioblastoma multiforme is characterized by bizarre multinucleated giant cells with abundant eosinophilic cytoplasm, paucity of vascular endothelial proliferation, and increased reticulin fibers. It is considered by Rubinstein to be a variant of glioblastoma multiforme and by Zülch to be of mesenchymal origin. We studied retrospectively ten cases of giant-celled glioblastoma to correlate clinical and pathological features including immunohistochemistry and ultrastructure, radiology and survival time. Seven men and three women ranging in age from 23-75 years had variable clinical presentations and well defined lesions on computed tomography (eight patients). Well-defined at surgery, the tumor was located in temporal (six patients), frontal (three patients), and parieto occipital (one patient) lobes. Besides characteristic histology, glial-fibrillary acidic protein was positive in all, along with intracytoplasmic fibrils on electron microscopy. Three patients died within 3 days of surgery. Of the surviving seven treated with radiation and/or chemotherapy, three had a survival time of more than 36 months and four less than 15 months. Our study identifies this tumor to be of astrocytic lineage, with temporal lobe predilection, and overall a longer survival rate than glioblastoma multiforme.

A serially transplantable human giant cell glioblastoma that maintains a near-haploid stem line

We have karyotyped a human giant cell glioblastoma removed from an 11-year-old girl and have established from it a subcutaneously transplantable line in athymic nude mice. The original tumor contained near-haploid cells with 25 or 26 chromosomes, including two copies of #1, (7 or 7p+) and #18. There were also hyperdiploid (49-52) cells that were tetraploid for these same three chromosome types; doubled versions of the hyperdiploid population were also seen. The stemline of the mouse-grown tumor was 26,X, +1, +7p+, +18 in the first passage and has remained consistently near-haploid through ten serial in vivo passages. Growth stabilization has occurred with an average latency of less than 3 months. This transplantable line is available for evaluating chemotherapeutic responsiveness of human giant cell glioblastoma and for studying near-haploidy in solid human tumors.

Gangliocytoma of the pineal body. A case report and review of the literature

Ganglion cell tumours are mostly seen in children and young people, but they are extremely rare, accounting for 0.1-0.5% of all brain tumours. It usually occurs in the floor of the third ventricle and the temporal lobe. Recently we have experienced a pineal gangliocytoma, probably the first ever seen in Japan and the fourth case in the world, and have succeeded in a total removal of it. The case concerns a 51-year-old man who suffered from intermittent blurred vision and headache of 3 years' duration. CT showed, together with severe hydrocephalus, positive contrast medium enhancement and a somewhat irregular but sharply circumscribed high density lesion suggestive of a meningioma. But the brain scintiscan revealed a badly and irregularly demarcated region of warm activity and having little change with time mainly in the pineal region, which was strongly suspicious of gliomas. Hence this scan was thought to be important in diagnosing this tumour. As an operative procedure, biparieto-occipital craniotomy was successfully performed in the "sea lion" position to remove the tumour totally. Pathological findings indicated a mixture of dispersion and concentration of giant cells possessing prominent nucleoli, abundant chromatin and a prominent nucleus or several nuclei of varying sizes and process-like cell bodies polygonal or irregular in shape. GFAP stain showing no glial fibres and the tumour was thought to be a gangliocytoma.

Brain tumor of mixed mesenchymal and neuroepithelial origin. Case report

✓ A case is reported in which the intracerebral tumor was a mixed mesenchymal and neuroepithelial (glial) neoplasm. The mesenchymal part contained both lymphoma and dedifferentiated meningioma; the neuroepithelial portion was glioblastoma multiforme. The combined tumor had both gross and microscopic features of a “giant cell sarcoma” and “giant-celled glioblastoma.” The findings in this case and a review of the literature indicate the mixed mesenchymal and neuroepithelial origin of these tumors.
