Seven cytopathologists brought FNA cases (a mixture of atypical and non\u2010atypical FNA diagnosis) diagnosed using TBSRTC from their respective institutions which were reviewed and diagnosed by the participants. The analysis assessed interobserver variability among 7 cytopathologists and determined characteristics on the slides which were associated with concordance to the institutional diagnosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Seventy eight of 125 (62.4%) benign cases were classified as benign by the reviewers and 26 (21%) were called AUS\/FLUS on review. A third of the AUS\/FLUS cases were called benign on review and 28.2% were classified as suspicious for neoplasia\/malignancy. Roughly a third each of the suspicious for follicular neoplasm\/suspicious for malignancy cases were classified as AUS\/FLUS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>When pathologists from different institutions shared their slides, concordance was high for specimens with adequate cellularity and those that were clearly benign but thresholds varied for the other indeterminate categories.
