Pleomorphic xanthoastrocytoma (PXA) is a superficial, circumscribed rare glial tumor with the typical location in the cerebral hemispheres, particularly in the temporal and parietal lobes. Microscopic features include marked cellular pleomorphism, nuclear atypia, increased mitotic index and presence of necrosis. It affects children and young adults, and has a relatively favorable prognosis with ten-years relapse- free survival, and overall survival of 61% and 70% respectively. Surgery remains the mainstay of treatment, the roles of adjuvant irradiation and chemotherapy remains undefined. Radiotherapy with total doses of 30-60 Gy, delivered in the conventional fractionation regimen is recommended after subtotal resection, and in patients who have anaplastic variant of PXA. Extent of resection, the value of mitotic index and presence of necrosis are the recognized factors influencing clinical outcome.
