Context.—The Bethesda System for thyroid fine-needle aspirates does not account for the size of the lesion that is aspirated. Objective.—To determine whether the size of the lesion would be helpful in order to reduce indeterminate thyroid aspirations. Design.—We correlated the results of all thyroid aspirations and surgical resection for the last 16 years at our institutions. Results.—A total of 9080 cases were aspirated and 1393 resections were performed. Of those resected, a total of 236 (17%) were classified as atypical follicular cells of undetermined significance, and 256 (18%) were classified as suspicious for a follicular/Hürthle cell neoplasm. A total of 52 incidental papillary carcinomas were identified in these indeterminate cases at resection (52 of 492; 11%). Thirty-seven (16%) atypical follicular cells of undetermined significance cases and 21 (8%) suspicious for a follicular/Hürthle cell neoplasm cases were for nodules smaller than 1 cm in diameter. When cases subtyped as atypical, a papillary carcinoma cannot be ruled out, were removed (13 cases), the remaining 24 and 21 aspirates identified 3 tumors each (13% and 14%), all papillary carcinomas. Together, the incidence of identified carcinomas was not significantly different than that of incidental carcinomas (13% versus 11%, P = .48). The rate of identified carcinomas was significantly less than for similar indeterminate cases smaller than 1 cm (excluding cases of atypical, papillary carcinoma cannot be ruled out) (88 of 330 cases; 27%; P = .05). Conclusions.—For nodules smaller than 1 cm in our series, indeterminate aspirates without features of papillary carcinomas have the same risk of malignancy as benign aspirates.

Introduction: False-negative thyroid fine-needle aspirates (FNA) are not well characterized. Methods: We correlated the results of all thyroid aspirations from 1997 to 2016 with histologic follow-up. Results: There were 13,733 aspirates, 2,112 (15.3%) resections, and 678 malignancies (32.1%). Eighteen (2.7%) false-negative cases were identified (interpretation, n = 6; sampling, n = 7; and new nodules, n = 5). Interpretive false-negative cases were significantly less likely when the indeterminate rate was greater than 13% (p = 0.01). Interpretive errors involved rare cells with poorly developed features of malignancy. Sampling errors were not associated with scant cellularity in the specimen. The majority of false-negative cases were not resected because of a clinical suspicion of malignancy. The sensitivity of FNA for 9-mm papillary carcinomas was 44.3%. Conclusion: In this cohort, the false-negative rate of thyroid FNA was 2.7% and the risk of malignancy for a benign diagnosis was 3.5%. Interpretative errors involved rare cells with poorly developed features of malignancy. There is little evidence that either the false-negative rate or the risk of malignancy of a benign thyroid FNA is different in patients who do and do not undergo resection.

ABSTRACT Cytodiagnostic fine needle aspiration biopsy specimens from toxic goitres were studied for signs of lymphoid infiltration. Comparison with histological sections of specimens obtained by surgery showed that an excess of lymphoid cells in the aspirate smears corresponded to a large number of lymphoid foci in these sections. Excess of lymphoid cells in the fine needle aspirates was also positively correlated with the occurrence of circulating thyroid antibodies against thyroglobulin and/or cytoplasmic antigen, but not with the presence of the long-acting thyroid stimulating factor, LATS. It also varied with age in that it was most common in the youngest patients and in patients between 40–55 years, while lymphoid infiltration was seldom seen in patients over 55 years. A finding of practical clinical interest was that in toxic goitres with cytological signs of lymphoid infiltration hyperthyroidism had less tendency to recur after treatment with thiocarbamide drugs than in those without such signs.
