Humaira Nasir and Anwar Ul Haque
Department of Pathology, Pakistan Institute of Medical Sciences, Islamabad.


Intra-operative diagnosis of brain tumours routinely employs frozen sections. The frozen section however has several
limitations and induces serious freezing artefacts. We carried out a prospective study on 40 cases of astrocytomas utilizing touch preparation cytology. The smears were quite cellular with crisp cellular details. There was 98.4% sensitivity and 90% specificity. We found touch preparation cytology highly reliable mode of intra-operative diagnosis in astrocytomas.
