1 IntroductionThyroid nodules (TN) are localized morphological changes in the form of lumps that occur in the thyroid gland (1), and the nodules can be benign or malignant (2, 3). It is estimated that the frequency of identifying palpable TN by physical examination is 2-6%, while TNs observed by ultrasound (US) are described in 19 to 49% of cases (2, 4, 5) and in 8-65% of autopsy cases (6, 7). Moreover, the incidence of malignant TN is significantly lower and accounts for <5% of all TNs (3).
