Role of squash-smear technique for rapid diagnosis of neurosurgical biopsies--a cytomorphological evaluation.

ABSTRACT

The biopsy material obtained from lesions of CNS are subjected to squash smear technique for rapid diagnosis as it is easier to make and the cytological features of cells are well preserved. During the year 1982-1983 one hundred and seventy eight squash smears were made to offer rapid diagnosis to the operating surgeon. The diagnosis was verified on paraffin sections. Correct diagnosis was made in 87% of cases. Various lesions have distinct cytomorphological features on smears. These distinct characters and efficacy of the method are discussed.
