background: fine needle aspiration (fna) has led to a decrease in unnecessary surgeries for thyroid nodules. this study was designed to compare diagnostic value of fna and frozen section methods in the follicular lesions. methods: this is a cross-sectional study based on the medical records of 42 patients who were referred to surgery clinic of rasool-e-akram hospital in tehran with complaint of...

BACKGROUND The controversy that iodized salt may increase the risk of thyroid disorders has arisen in China during the past several years. OBJECTIVE This study aimed to explore whether iodized salt increased the risk of thyroid nodule among a Chinese population. DESIGN A cross-sectional study was conducted in Hangzhou, China, in 2010. Iodized salt intake, urinary iodine concentration (UIC),...

BACKGROUND Cold thyroid nodules are common, in particular in iodine-deficient areas, but only a minority of them are malignant requiring surgery. Thyroid peroxidase (TPO) immunostaining of fine-needle aspiration cytology (FNAC) material has proven helpful in diagnosing cells from malignant lesions, but the procedure has its limitations in a routine setting. PURPOSE To improve diagnosis and re...

The occurrence of thyroid nodules increases with age [1]. In geographical areas with a normal iodine intake, approximately 10% of the population develops a palpable thyroid nodule. This proportion increases in areas with insufficient iodine intake. Non-palpable thyroid nodules are usually diagnosed by a neck echography carried out for various reasons and are 5-10 folds more common than palpable...

CONTEXT There are an increasing number of studies analyzing gene expression profiles in various benign and malignant thyroid tumors. This creates the opportunity to validate results obtained from one microarray study with those from other data sets. This process requires rigorous methods for accurate comparison. OBJECTIVE The ability to compare data sets derived from different Affymetrix Gene...

A thyroid nodule is a very common condition which can be found among 40 to 50% of general population on ultrasound. Identification of thyroid cancer cells through fine needle aspiration (FNA) is a gold standard for diagnosis of thyroid cancer. Among all thyroid nodules, thyroid cancer occupied five to ten percent, and thus a large number of patients, even with benign thyroid nodules, are recomm...

BACKGROUND Thyroid nodules are commonly found on medical imaging studies, such as Computerized Tomography (CT) scans, 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/CT (PET/CT) scans, or other imaging studies, which are performed for another reason (ie. the test is ordered without knowledge of the presence of a thyroid nodule). When thyroid nodules are detected on imaging studies...

Thyroid benign lymphoepithelial lesions are rare in adults, reported as associated with thyroiditis or adjacent to tumours. Here we report a unique case of a thyroid solid nodule with benign lymphoepithelial morphology. A 56-year-old woman presented with a thyroid nodule increasing in size. Thyroid function was normal. On the surgical resection specimen, in addition to a 2-cm follicular adenoma...

A 68-year-old woman with solid/trabecular follicular thyroid carcinoma inside of an autonomously functioning thyroid nodule is described in this paper. The patient was referred to our clinic for swelling of the neck and an increased pulse rate. Ultrasonography showed a slightly hypoechoic nodule in the right lobe of the thyroid. Despite suppressed TSH levels, the (99m)Tc-pertechnetate scan show...
