Bottom Line: Typical cytopathological aspects and/or classical histopathological findings were taken into consideration in the diagnosis of HT, and only histopathological results were considered in the diagnosis of PTC.In spite of the absence of association between HT and PCT, the possibility of malignancy in HT should always be considered because of the coexistence of the two diseases already reported in the literature.Abstract available from the publisher.

ABSTRACT

Objective: To evaluate the association between Hashimoto's thyroiditis (HT) and papillary thyroid carcinoma (PTC).

Materials and methods: The patients were evaluated by ultrasonography-guided fine needle aspiration cytology. Typical cytopathological aspects and/or classical histopathological findings were taken into consideration in the diagnosis of HT, and only histopathological results were considered in the diagnosis of PTC.

Results: Among 1,049 patients with multi- or uninodular goiter (903 women and 146 men), 173 (16.5%) had cytopathological features of thyroiditis. Thirty-three (67.4%) out of the 49 operated patients had PTC, 9 (27.3%) of them with histopathological features of HT. Five (31.3%) out of the 16 patients with non-malignant disease also had HT. In the groups with HT, PTC, and PCT+HT, the female prevalence rate was 100%, 91.6%, and 77.8%, respectively. Mean age was 41.5, 43.3, and 48.5 years, respectively. No association was observed between the two diseases in the present study where HT occurred in 31.1% of the benign cases and in 27.3% of malignant cases (p = 0.8).

Conclusion: In spite of the absence of association between HT and PCT, the possibility of malignancy in HT should always be considered because of the coexistence of the two diseases already reported in the literature.

f01: Coexistence of Hashimoto thyroiditis in patients with diagnosis of benignity andmalignancy in thyroid nodules (papilliferous thyroid carcinoma).

Mentions: Amongst the 1,049 patients presenting with nodular goiter, 173 (16.4%) presented withcytopathological signs of thyroiditis. Among the 49 patients submitted to surgery, 5(10.2) were histopathologically diagnosed with HT, 33 (67.3%) presented PTC, 9 (27.3%)of them with concomitant histopathological diagnosis of HT. Two patients (4.2%) hadmedullary carcinoma whose cytopathological diagnoses were confirmed at histopathology.Among the ten patients submitted to surgery due to increased nodular volume, 5 (31.3%)also presented with HT and one PTC case was histopathologically diagnosed (one case offalse-negative result). In the present study, no association was observed between PTCand HT. Hashimoto thyroiditis was present in 31.1% of the benign cases and in 27.3% ofthe malignant cases (Fisher's exact test, p = 0.8) (Figure 1).
