Pleomorphic xanthoastrocytoma of the cerebellum

We report a clinicopathologic case of a pure cerebellar pleomorphic xanthoa strocytoma occurring in a 68-year-old male patient. The occurrence of pleom orphic xanthoastrocytoma outside the cerebral hemispheres is exceedingly ra re. In the cerebellum only five cases have been reported so far, four of wh ich are composite pleomorphic xanthoastrocytoma-gangliogliomas. This observ ation reinforces the argument that pleomorphic xanthoastrocytomas should be included in the differential diagnosis of cerebellar neoplasms.
