Abstract

Abstract : Background: Fine needle aspiration cytology (FNA) is a simple, safe, cost effective, and accurate method for diagnosis of cystic lesions of the breast. Our study aims to correlate FNA cytology of cystic lesions of the breast with the histologic diagnosis. Methods: During a period of 10 years (2007‐2017), 314 cases of breast cystic lesions were retrieved from a total 1073 cases of breast FNAs. Of these, 78 cases from 77 patients (mean age = 54.6, female: male = 76:1) with simultaneous FNA and core needle biopsy (CNB) and/or excision specimen were reviewed. The FNA cytology reports were correlated with the histology results of CNB ( n = 72) and breast excision ( n = 20). Results: Overall, 73 of 78 (93.6%) FNA cases were concordant with CNB and/or excision results. Fifty‐five benign FNAs were all concordant with histology and reported as benign (negative predictive value = 100%). The positive predictive value of FNA with a malignant diagnosis was 100%, 71.4% for a suspicious diagnosis, and 33.3% for atypical cytologic diagnosis. Two of six papillary lesions were discordant with the concurrent CNB, but the FNA results were concordant with the final histology on excision. Conclusions: FNA allows accurate diagnosis of benign cystic lesions. FNA also plays a prominent role in evaluating cystic papillary lesions of the breast and helps to prevent false negative results on the simultaneous CNB. It is essential that FNA and CNB diagnoses be used in combination to make the correct diagnosis and for clinical management.
