title: The sarcoma arising in giloblastoma: clinico-pathological report of two cases.
abstract: Two cases of primary brain tumor composed of an admixture of sarcomatous and gliomatous tissues are reported together with their clinical courses and neurosurgical examination. There is no difference in clinical course nor in the result of examination between the usual glioblastoma multiforme and these admixture tumor. The histological examination at the surgical biopsy and autopsy suggested that enoplastic change of the sarcomatous element occurs markedly on hyperplastic blood vessels in the glioblastoma multiforme. The neoplastic change observed on hyperplastic blood vessels is not affected by radiation therapy.
