Evaluation of accuracy of fine needle aspiration cytology in BI‐RADS3 category breast lesions: cytohistological correlation in 337 cases Objective: To evaluate the accuracy of fine needle aspiration cytology (FNAC) in BI‐RADS3 breast lesions. Methods: Between January 2004 and December 2007, 337 cases from BI‐RADS3 lesions underwent FNAC. Three to six needle passes were made on each patient. In 67 cases (20%) a histological biopsy was performed. Cytological and histological interpretations were performed by the same pathologist. Results: The histological diagnosis showed that 88% (59/67) of BI‐RADS3 breast lesions were benign. Only 6% (4/67) were malignant, consisting of ductal carcinoma in situ and infiltrating ductal carcinoma. Conclusion: BI‐RADS3 lesions remain disruptive in their management. However, the correlation between cytology and histology showed that most of these lesions were benign and that finally FNAC remains a useful and accurate test in the management of these lesions.
