Partially cystic thyroid nodules (PCTNs) are common on ultrasound (US). However, there are insufficient data on the prevalence of thyroid carcinoma among such nodules. The purpose of this study was thus to evaluate the prevalence and differentiation of partially cystic thyroid cancers in US-guided fine needle aspiration (FNA).A total of 1342 consecutive patients with 1360 thyroid nodules underwent prospective US diagnosis and FNA biopsy. In total, 281 nodules (20.7%) were partially cystic lesions. The nodules were prospectively analyzed based on US features (ie, solid portion positions, shapes, margins, and microcalcifications) and US diagnosis (benign, suspicious, or malignant)...

Silk suture reaction (i.e., a benign granulomatous inflammatory foreign body reaction) is a rare complication of thyroid surgery. Here, two cases of post-thyroidectomy suture reaction are presented. Both of the patients were female, one is 48 and the other is 34 years old. The patients were presented with neck swelling and leakage of serous fluid from the Kocher's incision. Both patients had normal free T4, free T3, and TSH values. The 48-year-old female patient had a right subtotal and left near-total thyroidectomy 6 years ago and the other had bilateral total thyroidectomy 6 years ago...

Graves' disease is the most frequent cause of hyperthyroidism in iodine-sufficient geographical areas and is characterized by the presence in patients' serum of autoantibodies directed against the thyrotropin receptor (TRAb) that cause overproduction and release of thyroid hormones. Clinical presentation results from both hyperthyroidism and underlying autoimmunity. The diagnosis is based on characteristic clinical features and biochemical abnormalities. If serum thyrotropin (TSH) is low, serum free thyroxine (FT4) and free triiodothyronine (FT3) concentrations should be measured to distinguish between subclinical (with normal circulating thyroid hormones) and overt hyperthyroidism (with increased circulating thyroid hormones)...

Nodular thyroid diseases are common in Turkey. Insulin resistance (IR) is considered as the most important component of metabolic syndrome (MetS), and it is thought to directly affect thyroid diseases, together with other components of MetS. The aim of this study was to evaluate potential factors associated with thyroid nodularity. This study was part of the prospective MELEN study. In total, randomly selected 2233 subjects were evaluated. A euthyroid subgroup of participants (n = 1432) was selected and 421 of them had MetS...

Ultrasonography is pivotal in triage thyroid biopsy in the era after the identification of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). This pictorial essay illustrates the pathologic basis of the sonographic features that distinguish NIFTP from thyroid cancers. In this study, we present the correlations of ultrasonography to ×1 histopathology to assess shape and margin characteristics. Markedly hypoechoic nodules correlate to microfollicular/solid nodules, while isoechoic/hyperechoic thyroid nodules correlate to normofollicular/macrofollicular nodules...

Ultrasonography is the first choice of lymph node metastasis (LNM) detection which is crucial for therapeutic options of papillary thyroid cancer (PTC). However, the sensitivity of ultrasonography in detecting LNM of PTC is relatively low; especially in central LNM. MiR-324-5p has been reported to play important roles in the metastasis of various cancers. To explore the relationship between miR-324-5p and LNM in PTC, quantitative real-time polymerase chain reaction was performed in PTC tissue and fine needle aspiration (FNA) washout successively...

Histological findings often display an association between papillary thyroid carcinomas (PTC) and autoimmune thyroiditis (AIT) and so differ significantly from follicular thyroid carcinomas (FTC). The aim of this interdisciplinary, retrospective study was to evaluate the association of AIT in patients with PTC and FTC and a control group of benign nodular goiters. One hundred thyroidectomies with histologically confirmed differentiated thyroid carcinomas, 67 with PTC and 33 with FTC, were submitted for examination...

BACKGROUND: The BRAF V600E mutation is highly specific for papillary thyroid carcinoma (PTC). A test for this mutation can increase the diagnostic accuracy of fine-needle aspiration cytology (FNAC), but a considerably high false-negative rate for the BRAF V600E mutation on FNAC has been reported. In this study, we investigated the risk factors associated with false-negative BRAF V600E mutation results on FNAC. METHODS: BRAF V600E mutation results of 221 PTC nodules between December 2011 and June 2013 were retrospectively reviewed...

INTRODUCTION: False-negative thyroid fine-needle aspirates (FNA) are not well characterized. METHODS: We correlated the results of all thyroid aspirations from 1997 to 2016 with histologic follow-up. RESULTS: There were 13,733 aspirates, 2,112 (15.3%) resections, and 678 malignancies (32.1%). Eighteen (2.7%) false-negative cases were identified (interpretation, n = 6; sampling, n = 7; and new nodules, n = 5). Interpretive false-negative cases were significantly less likely when the indeterminate rate was greater than 13% (p = 0...

BACKGROUND: We evaluated whether diagnostic thyroidectomy for indeterminate thyroid nodules would be more cost-effective than genetic testing after including the costs of long-term surveillance. METHODS: We used a Markov decision model to estimate the cost-effectiveness of thyroid lobectomy versus genetic testing (Afirma®) for evaluation of indeterminate (Bethesda 3-4) thyroid nodules. The base case was a 40-year-old woman with a 1-cm indeterminate nodule. Probabilities and estimates of utilities were obtained from the literature...
