Intracranial sarcoma with reactive glioma: a clinicopathological case report.

The clinicopathologic picture of a case of so-called 'sarcoglioma' is reported. This tumor is characterized by a core of sarcomatous tissue, surrounded by an area of gradual transition from reactive to neoplastic glial cells; it occurs in children or in young adults and is very rare in comparison with the secondary sarcoma deriving from the vascular component of a glioblastoma (so-called 'gliosarcoma'). The clinical and laboratory features and the pathology of this case are discussed in detail.
