Abstract
A cytological preparation of neurosurgical biopsy material is one
technique by which a rapid and reliable diagnosis can be made. Many specimens
unfit for sectioning may be used, and the detailed cytological nature of the tumor
can be evaluated, thus providing valuable information in differential diagnosis
from other primary tumors or metastatic lesions. Touch-print specimens of 48
cases of eNS tumors collected during the last year from 1991 are reviewed and
compared with paraffin sections of the same biopsies. Touch prints were
prepared with specimens for frozed section diagnosis, just before they were
utilized for frozen sectioning. Smears were stained both with Wright-Giemsa and
Papanicolaou methods. Fourty eight cases of brain tumors consisted of 14
pituitary adenomas, 11 meningiomas, 7 oligodendrogliomas, 4 astrocytomas, 3
glioblastoma multiforme, 3 malignant lymphomas, 2 chordomas, 2
neurilemmomas, 1 pineocytoma, and 1 craniopharyngioma. The cytology and
histology of pituitary adenoma and meningioma correlated best in this series. The
most consistent findings were monotonous eccentric round nuclei and plump
polygonal cytoplasm in the pituitary adenomas and meningothelial cell clusters
with whorling pattern and psammoma bodies in meningiomas. The main
dificulties encountered were differentiation between nonspecific glial hyperplasia
and low-grade astrocytoma as well as grading of astrocytoma and
oligodendroglioma. The remaining tumors revealed fairly consistent findings to be
correlated with biopsy specimens.
