Pleomorphic xanthoastrocytoma.

ABSTRACT

Pleomorphic xanthoastrocytoma is an unusual brain tumour of children with a favourable prognosis. The tumour takes origin from subpial astrocytes of the cerebral cortex. Histologically proliferation of spindle cells, mono and multinucleated giant cells containing lipid droplets and the absence of necrosis are distinctive features. Herein we report the morphological and immunophenotypical features of a case of pleomorphic xanthoastrocytoma.
