FNAC and Histopathological Correlation of Benign Breast Lesions

The overall diagnostic accuracy of cytology in diagnosing benign breast lesions was found to be 89.7% in this study. To study the cytomorphological spectrum of benign breast lesions on fine needle aspiration cytology and correlate FNAC findings with histopathological findings wherever available. Accuracy of Cytology for fibroadenoma was 92.1%, for fibrocystic disease was 88.9% and for gyanecomastia, abscess, phyllodes tumors was 100%. FNAC helps in preoperative evaluation of breast lumps without surgical intervention. However, overlapping features of different lesions can also cause cytodiagnostic errors. There exists a high degree of correlation with histopathological findings. In cases of discordance, histopathology remains gold standard diagnostic modality.
