Abstract Introduction: Thyroglobulin evaluation in the washout of fine-needle aspiration (FNA-Tg) is an accurate diagnostic method of lymph node metastases (LNM) of differentiated thyroid carcinoma (DTC). Serum anti-thyroglobulin antibodies (AATg) may cause falsely low serum Tg values, but their effect on FNA-Tg has not been well established. There are also concerns about the possibility that suppressed TSH results in false-negative FNA-Tg. Our objectives were to evaluate the effect of serum AATg and TSH level on FNA-Tg of LNM of DTC and to determine the presence of AATg on the washout of fine needle aspiration (FNA-AATg). Methods: Retrospective analysis of patients who underwent FNA-Tg assay in LNM of DTC. The sample was divided in two groups according to the presence of serum AATg at the time of FNA-Tg evaluation (Group 1: positive AATg, n =47; Group 2: negative AATg, n =50). Results: There was no significant difference in the FNA-Tg between the two groups ( p =0.066), although it was lower in Group 1 (1428 ng/mL) than in Group 2 (14842 ng/mL). FNA-Tg was able to identify 10.3% LNM of DTC that would not be diagnosed based solely on cytology. FNA-AATg evaluation was positive in 12.8% of the Group 1 patients and did not seem to interfere with FNA-Tg value ( p =0.732). There were no differences in the median FNA-Tg measurements between those on levothyroxine suppressive therapy and those on substitutive therapy ( p =0.800). Conclusion: FNA-Tg assay appears to be a good diagnostic tool even in patients with positive serum AATg and those under suppressive levothyroxine therapy.

Pulmonary sclerosing hemangioma is an unusual benign tumour of uncertain histogenesis. In the past 50 years, hundreds of cases have been described. A case of sclerosing hemangioma with some unusual features, including a false-positive fine needle aspiration biopsy and histological evidence of lymph node metastases, is described.
