Pleomorphic xanthoastrocytoma is histologically characterized by marked cellular
pleomorphism of lipid-laden neoplastic astrocytes and bizarre giant cells showing mitotic
figures and high cellularity. Inspite of its ominous-looking microscopic features, however,
the prognosis is usually favorable. This tumor develops mainly in the supratentorial area
of young people and frequently involves the leptomeninges.
We experienced a case of pleomorphic xanthoastrocytoma in 18 year-old-male. In
addition to the cellular pleomophism, the prominent reticulin fibers surround the
individual tumor cells or he tumor cell nests. Immunohistochemical staining and electron
microscopy revealed glial fibrillary acidic protein(GFAP) expression and pericytoplasmic
basal lamina in the tumor cells. Korean J Patrol 1993; 27: 666¡669)
