ObjectiveTo evaluate the incidence of focal lesions in the thyroid in the area of recently normalized iodine supply as well as to compare the efficacy of fine-needle aspiration biopsy (FNAB) of small (infracentimetric) and large thyroid lesions in this area.MethodsThe outcomes of 13 646 ultrasound (US) examinations, 13 437 US-guided FNABs of the thyroid and 1694 results of post-operative histopathological examinations were analysed.ResultsInfracentimetric nodules (INs ≤10 mm) were revealed by US examinations in 43.5% of patients; in the majority of the cases (82.2%) INs were multiple. The percentage of revealed carcinomas by aspiration of INs is similar to that observed when large nodules (LNs >10 mm) are examined cytologically. However, the efficiency of preoperative diagnosis of INs is lower than LNs with respect to both US selection of lesions for FNAB and the percentage of false negative results of FNAB (29.8 vs 5.4%, P<0.001). In post-operative histopathological examination, extrathyroidal extension of thyroid cancers was observed in nearly 30% of microcarcinomas.ConclusionsIn endemic or post-endemic areas, the efficiency of FNAB is lower in the case of small lesions than larger ones. In spite of this, the percentage of cytologically revealed carcinomas among small lesions is not lower than larger ones. Thus, it is particularly indicated to follow up small thyroid lesions with repeated US examinations in such areas.

Background: The stroma in fine-needle aspiration biopsy (FNAB) of thyroid lesions has not been well investigated. Design: We studied 256 consecutive cases of thyroid FNAB prepared with traditional smear technique. The stroma was categorized: Type 1a consisted of long (more than 3 mm), broad bands composed of mesh containing collagen fibrils thickened by entrapped blood components and follicular cells. Type 1b consisted of dense strands/bands. Type 2 was similar to Type 1a but with shorter (<2 mm) and looser stromal strands. Results: Types 1a and b showed straight/curved/circular branching patterns suggestive of incomplete frameworks of nodular/papillary architectures or fragments of capsule. Type 1b stroma likely represented thick/collagenized fibrous septae. Incomplete or complete rings of small encapsulated tumor were occasionally identified. These frameworks of stroma were frequently associated with multinodular goiters (MNGs) which are often hypocellular and follicular neoplasms/papillary thyroid carcinoma with increased cellularity. Type 2 was associated with microfollicles in encapsulated neoplasms or with macrofollicles in MNG. Follicular lesions of unknown significance (n = 41) either negative (n = 26) or positive (n = 15) for carcinoma in subsequent follow-up were frequently associated with stroma characteristic of MNG and carcinoma, respectively. Conclusion: The preservation of the in vivo architecture of Type 1 is likely due to its elasticity. Recognition of the stromal architecture will likely facilitate the diagnosis.

Background and aimsThe most commonly used diagnostic method for the preoperative diagnosis of thyroid nodules is ultrasound-guided fine-needle aspiration biopsy (FNA), which often yields non-diagnostic or non-definitive results and seldom produces definite malignant diagnoses. To improve upon the malignancy-specific sensitivity, we tested core needle biopsies (CNBs) of thyroid lesions taken from surgical specimens.Material and methods52 consecutive patients with malignant or malignant-suspicious thyroid nodules were referred to Tampere University Hospital between May 2010 and December 2011. Preoperative FNAs were categorised as follicular neoplasm (48%), suspicion for malignancy (46%) or malignancy (6%). Intraoperative FNA and CNB samples were acquired from surgical specimens removed during surgery. The results of the needle biopsies were compared with the final pathological diagnosis.ResultsCNBs had a high definitive sensitivity for malignancy (61%, CI 41% to 78%) whereas the definitive sensitivity for malignancy of FNAs was significantly lower (22%, CI 10% to 42%). CNB was not beneficial in the diagnosis of follicular thyroid lesions. When all suspected follicular tumours were excluded, the definitive sensitivity of CNB rose to 70% (CI 48% to 86%).ConclusionsCNB may be beneficial for the diagnosis of papillary thyroid carcinoma and other non-follicular thyroid lesions. CNB may be considered as an additional diagnostic procedure in cases with FNA suspicious for malignancy.
