A variant of cerebral glioma called pleomorphic xanthoastrocytoma: case report

A newly recognized type of cerebral astrocytoma has been described in the last 5 years among patients under the age of 30. The designation of pleomorphic xanthoastrocytoma has been suggested for this neoplasm on the basis of its unique histological features. These include abundant lipid droplets in the astrocytic cytoplasm. We report an additional case of this cerebral hemisphere astrocytoma, which (in common with 17 others reported before) occurred in a young patient. His postoperative course has been benign and he remains ambulatory and almost symptom-free 9 years after the initial tumor excision. The diagnosis of pleomorphic xanthoastrocytoma should be entertained in patients in whom a superficially placed intracerebral tumor (i.e., one that seems to be in contact with the meninges) develops during the juvenile years.
