Gliosarcoma cerebri with a myxoid matrix of the sarcomatous component.

A case of a cerebral gliosarcoma in a 63-year old female located in the left parietooccipital area of the brain is herewith described. Histology showed the tumour to consist of two components: a gliomatous resembling glioblastoma, and a sarcomatous with a prominent myxoid intercellular substance, a feature reported only thrice before in the medical literature. We report the histochemical and immunohistochemical characteristics of our case, and compare them with those of previous case reports.
