This study represents a statistical analysis and cytohistologic correlation of FNA in palpable malignant breast lesions performed at the FNA clinic of Goa Medical College during a seven-year period. Only the cases where subsequent histologic diagnosis was available were analysed. All the aspirations were performed by the pathologists. Out of a total of 582 cases, cytological diagnosis was malignant in 180 cases (30.9%). Four cases (1.3%) were false negative. There were no false positive cases in the study. A sensitivity rate of 97.8% and a specificity of rate of 100% was obtained for malignancy. Positive and negative predictive value for the diagnosis of malignancy was 100% and 98.6% respectively. Efficiency of the test was 99.1%. FNA specific diagnosis showed an overall agreement of 95.9% for malignant lesions. All these results compare favourably with the best reported in literature. All these factors can help the clinicians in the management of malignant breast lesions.
