INTRODUCTION: Hyperthyroidism is rarely associated with malignancy, but it cannot rule out thyroid cancer. Although there is published data describing this coexistence, thyroid carcinomas inside autonomously functioning nodules are uncommon. PRESENTATION OF CASE: A 49-year-old woman presented with a cervical mass, unexplained weight loss and anxiousness, sweating and insomnia. On physical examination, she had a palpable left thyroid nodule. Thyroid function tests showed suppressed TSH (<0,1 uUI/mL), thyroxine 1,44 ng/dL (normal range 0,70-1,48) and triiodothyronine 4,33 pg/mL (normal range 1,71-3,71)...

OBJECTIVE: To assess severity and factors of pain during high-intensity focused ultrasound (HIFU) ablation of benign thyroid nodules. METHODS: 128 patients who underwent a HIFU ablation for a benign thyroid nodule were analysed. All patients received a bolus of intravenous pethidine and diazepam before treatment. After treatment, patients were asked to rate their overall pain experience on a visual analogue scale (0-100) (0 = no pain; 100 = worse possible pain) during treatment, 2 h after treatment and the following morning...

INTRODUCTION: Anaplastic thyroid carcinoma (ATC) is one of the most aggressive human malignancies and constitutes approximately 1.6-5% of malignant neoplasms of thyroid. ATC usually presents with local symptoms due to rapidly enlarging thyroid mass, and has only seldom been reported to be a cause of thyrotoxicosis. Up to date only 9 cases of ATC presented with thyrotoxicosis have been described. CASE REPORT: We report a case of 66-year-old woman, who had had a large, euthyroid multinodular goiter for almost 50 years...

Background: Ultrasonography (US) is being recognized as a traditional way of the diagnosis of various thyroid disorders, and this will help in detecting the thyroid tumors in early stage. Thyroid nodules are common and usually benign; steps to diagnose malignancy should include a careful clinical evaluation, laboratory tests, a thyroid US exam and a fine-needle aspiration (FNA) biopsy. Methods: A total of 173 registered cases were used for analysis in this study...

Background: Thyroid cancer is the most commonly reported endocrine malignancy, and its increased incidence has been the highest in all human tumors in recent decades. To investigate the mechanism of papillary thyroid cancer (PTC) occurrence and progression, we performed RNA sequencing and found an upregulated gene, LAMB3. However, the biological function of LAMB3 is still not clear. Materials and methods: We analyzed LAMB3 expression using The Cancer Genome Atlas (TCGA) database and hypothesized LAMB3 to be a gene associated with PTC...

BACKGROUND/PURPOSE: The thyroid gland is an uncommon site for the presence of extramedullary hematopoiesis (EMH). We report the cases of four Taiwanese women with hematopoietic elements on the smears of thyroid fine needle aspiration (FNA) samples and compare the findings with those of previously reported cases. METHODS: We retrieved the data of cases in which thyroid FNA performed between January 2000 and December 2016. The clinical manifestations, laboratory data, and image findings of cases with thyroid EMH were reported...

OBJECTIVE: To examine the association between the appearance of hyperechoic marks (HEMs) during high-intensity focused ultrasound (HIFU) ablation of benign thyroid nodules and nodule shrinkage at 6 months. METHODS: One hundred and thirty-six patients who underwent HIFU for benign thyroid nodule were analysed. An independent person carefully examined the B-mode ultrasonography screen for the appearance of HEMs after each pulse. The proportion of HEMs (%) was calculated by: [(Number of pulses that resulted in HEMs) / (Total number of pulses given per treatment) × 100] while the nodule shrinkage was measured by volume reduction ratio (VRR) = [Baseline volume-volume at 6 months]/[Baseline volume] * 100...

Background: The majority of patients diagnosed with oropharyngeal squamous cell cancer (OPSCC) are due to HPV infection. At present, there are no reliable tests for screening HPV in patients with OPSCC. The objective of this study was to assess the Cobas® HPV Test on oral rinse specimens as an early, non-invasive tool for HPV-related OPSCC. Methods: Oral rinse specimens were collected from 187 patients (45 with OPSCC, 61 with oral cavity SCC (OCSCC) and 81 control patients who had benign or malignant thyroid nodules) treated at MSKCC...

A 66-year-old woman was referred to our institute for an enlarging tumor of the thyroid, and neck and chest computed tomography scan showed not only a thyroid tumor, but also an anterior mediastinal tumor and ground-glass nodules in the lung. Because of persisting symptoms, an enlarging thyroid mass, and the possibility of cancer, excision of the tumors was proposed. A 6-cm-long vertical skin incision was made in the right axilla, a mini-thoracotomy was made in the third intercostal space, and an additional port was placed in the fifth intercostal space...

To evaluate the diagnostic performance of elastography alone and combined with Thyroid Imaging Reporting And Data System (TIRADS) for the assessment of non-autonomous thyroid nodules. We included 244 thyroid nodules and analyzed the visual elasticity scores, strain value (SV) and TIRADS classification. Histologic examination revealed 38 malignant (16%) and 206 benign nodules. The SV was lower in malignant nodules than in benign with an optimal cutoff ≤0.225. The visual elasticity scores showed a better diagnostic performance than the SV measurement...

Simultaneous existence of parathyroid adenoma and thyroid nonmedullary carcinoma is rarely observed. A 52-year-old female was diagnosed approximately 4 years ago with primary hyperparathyroidism (PHPT) on the basis of hypercalcemia and elevated serum parathyroid hormone (PTH) level. Clinically, PHPT diagnosed patient was examined with Tc-99m MIBI scintigraphy to investigate parathyroid adenoma. Early Tc-99m MIBI images showed focal focused enhanced activity retention on both thyroid left lobe upper pole and thyroid lower pole inferior neighborhood...

OBJECTIVE: Microwave ablation (MWA) is an effective technique for the treatment of benign thyroid nodules. The aim of this study was to investigate whether it is necessary to study changes in variables other than the volume reduction between follow-up intervals. This study also introduced the index R (Ssurface/V) to explore whether it could reflect features of shape between follow-up intervals. MATERIALS AND METHODS: A total of 236 complex benign thyroid nodules in 230 patients who underwent MWA in our department from October 2013 to February 2017 were included...

Background: Thyroid and breast nodules (BNs) are common, their prevalence varying based mainly on the population (including age, residence in area of different iodine availability) studied and methods used. The coincidence of thyroid and breast diseases remains controversial and the majority of the studies evaluate the association between breast cancer and thyroid disorders. Here we describe our experience of such association in a non-oncological series. Methods: Between the years 2000 and 2005, 3,372 patients from outpatient clinics were referred for thyroid ultrasonography (US) at our University Hospital; concurrent breast US in the 1,896 women revealed the presence of BNs in 127...

Indeterminate thyroid cytology (Bethesda III and IV) corresponds to follicular-patterned benign and malignant lesions, which are particularly difficult to differentiate on cytology alone. As approximately 25% of these nodules harbor malignancy, diagnostic hemithyroidectomy is still custom. However, advanced preoperative diagnostics are rapidly evolving.This review provides an overview of additional molecular and imaging diagnostics for indeterminate thyroid nodules in a pre-operative clinical setting, including considerations regarding cost-effectiveness, availability, and feasibility of combining techniques...

The distinction between follicular thyroid carcinomas (FTCs) and follicular-patterned benign lesions is almost impossible on fine-needle aspiration cytology. Furthermore, minimally invasive FTCs (MI-FTCs) with less than 4 vascular invasion foci generally have an excellent prognosis, but there are exceptions and, so far, no molecular marker appears able to identify them reliably. We aimed to distinguish benign lesions from low- and high-risk FTCs by a small-scale combination of genes. The expression analysis of 75 selected genes was performed on 18 follicular adenomas (FAs), 14 MI-FTCs and 6 widely invasive FTC (WI-FTCs)...
