In our centre, thyroid core-biopsy (CB) has replaced fine needle aspiration biopsy (FNAB) in the study of thyroid nodules because its better accuracy. International guidelines recommend repeating the FNA in cases of inadequate or insufficient first specimen, but nothing is published about the case in failed CB.Objective: To study the differences between nodules with inadequate and diagnostic thyroid Core Biopsy and the accuracy of repeating a CB after a ...

Current guidelines suggest sonographic follow-up in thyroid nodules smaller than 10 mm with intermediate or highly suspicious features as ultrasound-guided FNAC has poor results in these nodules, and the risk of non-diagnosed thyroid carcinoma is very low. CNB has proved superior to repeated FNAC in case of insufficient or indeterminate first FNAC.Objective: Evaluate diagnostic accuracy of CNB in nodules smaller than 10 mm with intermediate or high suspi...

CNB is increasingly being used as a diagnostic test for thyroid nodules with an inadequate (Bethesda 1) or indeterminate (Bethesda 3 and 4) FNAC results, which can account for up to 30% of the samples in some studies. CNB, using larger specimens and histological sections rather than cytological samples, allows better definition. We propose a simplified four-tiered classification of CNB specimens instead of the Bethesda system and evaluate its efficiency compared to definitive ...
