The cytology and surgical resection slides of cases from this RCA cohort were reviewed. The demographic parameters, clinical features, radiologic characteristics, usage of rapid on\u2010site evaluation (ROSE), corresponding surgical diagnosis, and repeat FNA were noted.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 2292 FNAs were performed between 2013 and 2023, of which 354 cases were ND. RCA was performed on 57 (16%) ND FNA cases that had corresponding surgical resection. The causes were grouped as man, method, machine, and material related. The primary cause predominantly was man\u2010related sampling errors in 36 (63%) cases. There were no interpretative errors by the pathologist. The second most common primary cause was material related, found in 21 (37%) cases, due to cystic, fibrotic, vascular, and small lesions. The most common secondary cause was method related, in which 41 (72%) cases had no image guidance. There were no machine\u2010related causes. The risk of malignancy in the RCA cohort was 17%.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Majority causes of ND cytology were method\u2010related due to lack of image guidance and ROSE.
