Pleomorphic xanthoastrocytoma is a rare tumor, Presenting superficially over the
cerebral hemispheres of young subjects. We report a case of pleomorphic
xanthoastrocytoma of the cervical cord in view of its unusual location.
The patient is a 20-year-old female, presenting with left neck Pain radiating to the
left shoulder one month before the admission. Magnetic resonance imaging revealed a
high signal lesion in the upper cervical cord and lower brainstem in T2 weighted image.
On operation, intramedullary tumor was present and it was relatively well delineated.
Near-total removal of the spinal cord mass was done. Microscopically, the tumor was
composed of Pleomorphic astrocytes, which were spindle-shaped with cytoplasmic
processes and hyperchromatic nuclei. Other cells were round with vesicular nuclei and
abundant eosinophilic cytoplasm.4 few giant cells were seen. Despite the marked
pleomorphism, mitosis or necrosis was not encountered. Scattered foamy cells were also
seen, which showed negative staining in GFAP immunostaining in contrast to other
GFAP-positive tumor cells. (Korean J Pathol 1993; 27: 184¡­186)
