[Primary multiple sarcoma of the brain and spinal cord].

The authors present a rare case of primary multiple sarcoma of the brain and spinal cord. Histologically the tumor was differentiated with meningeal sarcoma and glioblastoma. The diagnosis of a sarcoma was based on the existence of densly located polymorphic cells with a large amount of ugly gigantic cells and a dissemination of them along the vessels, the presence of collagenic filaments not only in the walls of the vessels, but between the tumor cells. The morphological pictures of the tumor in the brain and spinal cord were identical.
