RESUMO
Imprint cytologic examination should be performed in all cases of frozen sections, especially when tumor or infectious agents are suspected. It has been shown to be a useful adjunct to the use of frozen sections. It gives superior results in cases of small biopsied specimens, lymph nodes, infective cases, isolated tumor cells or hemorrhagic tissue. From our series of 80 cases, the total diagnostic accuracy was 29/32 cases (90.6%) for benign tumors, 45/48 cases (93.7%) for malignant tumors, with 2/80 cases (2.5%) of false positive rate in borderline ovarian tumors, and 4/80 cases (5%) of false negative rate, in which 3 cases were due to insufficient material.

Fine needle aspiration of the lung is an excellent method in the diagnosis of lung cancers, mediastinal tumors and other specific inflammatory lung lesions. The correct diagnosis of lung cancer by FNA in this study was a reported sensitivity of 97.8 per cent and specificity of 100 per cent. There was no false positive in this study, and only 1/60 patient had pneumothorax, which was cured after insertion of chest drain.
