Thyroglobulin in the washout fluid of lymph-node biopsy: what is its role in the follow-up of differentiated thyroid carcinoma?

Background: The clinical evaluation of enlarged local lymph nodes (LNs) is difficult at the beginning and throughout the follow-up of differentiated thyroid carcinoma (DTC). Although the examination of samples collected from LNs by fine-needle aspiration biopsy cytology (FNAB-C) is extremely specific for the diagnosis of metastases, its sensitivity is low, especially in paucicellular samples.

Summary: The measurement of thyroglobulin (Tg) in the fine-needle aspiration biopsy (FNAB) washout fluid (FNAB-Tg) increases the diagnostic performance of cytology to up to 100% sensitivity and specificity.

[Atypical form of acute suppurative thyroiditis in pediatric patient: case report].

Acute thyroiditis is an unusual disease. In pediatric patients it is usually associated with congenital abnormalities towards the unilateral envelopment of the left thyroid lobe. In general, in the absence of preexisting thyroid disease, the thyroid function is most often normal.
