Intracerebral granular cell tumor. Case report.

The authors report a case of intracerebral granular cell tumor. These neoplasms are uncommon and, particularly, the intracerebral location has been reported only in ten previous cases. The authors discuss the clinical and histological features of these lesions, the histogenesis of which is still controversial. Our data seem furthermore to support the theory that at least in most cases, granular cell tumors are derived from Schwann cells.
