Differentiation of benign and malignant thyroid nodules is crucial for clinical management. Here, we explored the efficacy of next‑generation sequencing (NGS) in predicting the classification of benign and malignant thyroid nodules and lymph node metastasis status, and simultaneously compared the results with ultrasound (US). Thyroline was designed to detect 15 target gene mutations and 2 fusions in 98 formalin‑fixed, paraffin‑embedded (FFPE) tissues, including those from 82 thyroid cancer (TC) patients and 16 patients with benign nodules...

Hyalinizing trabecular tumor (HTT) is a rare thyroid tumor with low to minimal malignant potential. HTT is often misinterpreted as other thyroid tumors, including papillary thyroid carcinoma (PTC) and medullary thyroid carcinoma (MTC), on fine-needle aspiration (FNA) cytology, because of its overlapping cytologic features, such as nuclear grooves and intranulcear pseudoinclusions. Although cytopathologists cannot definitely conclude HTT by FNA cytology, suspicion of HTT is necessary to avoid misdiagnosing HTT as PTC or MTC and to avoid unnecessary aggressive treatment...

Objectives: Fine-needle aspiration (FNA) of thyroid lesions may result in infarction and diagnostic difficulties on subsequent thyroidectomy specimens. Next-generation sequencing (NGS) methods for detection of hallmark driver BRAF V600E mutations may help characterize such tumors in which histologic alterations preclude definitive tissue diagnosis. Methods: Thyroidectomy specimens with both malignant FNA diagnoses and resultant infarction were identified from our institutional database...

OBJECTIVE: The second edition Bethesda System for Reporting Thyroid Cytology estimates 6-18% malignancy rate of category III (B3) and 10-40% for category IV (B4) nodules; however, reported malignancy rates have considerable variability among institutions. Use of molecular classifiers (including Afirma Gene Expression Classifier, GEC) can be utilized in management of thyroid nodules. Our objective was to analyze malignancy rates of B3 and B4 nodules and determine clinical outcomes of GEC Benign nodules...

Context: Adults with differentiated thyroid carcinoma (DTC) and Graves Disease (GD) demonstrate a greater reported disease burden and aggressive DTC behavior. To date, no studies have examined the impact and long-term outcome of concurrent GD and DTC (GD-DTC) in pediatric and young adults. Design: Single institution, retrospective longitudinal cohort study between 1997-2016. Participants: 139 pediatric and young adults with DTC, diagnosed at median age 15 (range 5-23) years compared to 12 GD-DTC patients, median age 18 (range 12-20) years...

Background: The thyroid gland is resistant to microbial infection, because of its organ characteristics such as encapsulation, iodine content, and rich blood supply. Therefore, acute suppurative thyroiditis (AST), as a bacterial infection of the thyroid gland, is rarely seen. AST typically takes places on the left side the neck region in children, because of the coincidence of the left piriform sinus fistula, as a most common route of infection. AST is also usually seen in immunocompromised hosts...

Carcinoma arising in lingual thyroid is an extremely rare entity accounting for only 1% of all reported ectopic thyroids. Here, we report a case of carcinoma arising in lingual thyroid, which has been successfully managed by transoral resection and bilateral neck dissections. A lingual mass 4-cm in diameter with calcification was incidentally detected by computed tomography at medical check-up. No thyroid tissue was observed in normal position. Ultrasound examination showed bilateral multiple lymphadenopathies...

In this paper, we aim to focus on false positive results in the evaluation of thyroid aspirations, covering cystic, inflammatory, follicular and oncocytic lesions, papillary carcinoma, and medullary carcinoma of thyroid. The recently described entity, "noninvasive follicular thyroid neoplasm with papillary-like nuclear features" (NIFTP), is also discussed detailing the impact of its introduction on the sensitivity and specificity of thyroid FNA, as well as the use of molecular tests for diagnostics...

BACKGROUND: A higher prevalence of thyroid nodules/carcinoma in females is well-known from the literature. The reasons for this difference are not fully explained. We intended to assess gender variation in the referral for ultrasound-guided fine needle aspiration (FNA) of thyroid nodules, to study reasons for gender referral differences, and to assess differences in nodules characteristics between genders. METHODS: Included were 272 consecutive patients, with 290 nodules submitted to FNA...

Carcinoma associated with thyroglossal duct cyst (TDC) is extremely rare and when it occurs it is invariably papillary carcinoma. A 36-year-old man presented with a midline swelling in the upper part of neck, which was a cystic lesion with multiple septae in ultrasonogram, indicating a thyroglossal duct cyst. The CT scan findings also corroborated the ultrasound report. Fine needle aspiration (FNA) smears showed hemosiderin laden cyst macrophages and occasional papillary cluster of neoplastic cells with central psammoma body and rare intranuclear cytoplasmic inclusions...

BACKGROUND: The American Thyroid Association (ATA) recommends fine-needle aspiration (FNA) biopsy of nodules measuring >1.5 cm with low-suspicion sonographic patterns or >1.0 cm with high/intermediate-suspicion features. Routine biopsy of nodules <1 cm is not recommended. However, despite these recommendations, subcentimeter nodules are often referred for FNA biopsy. METHODS: This was a retrospective chart review of consecutive thyroid FNAs during an 18-month period (1157 patients, 1491 nodules, 2016-2017) to evaluate age, sex, medical history, diagnoses, and follow-up...

Thyroid cancer is the most common malignancy of the endocrine system and includes well-differentiated forms, namely papillary and follicular carcinomas, and the poorly differentiated and undifferentiated forms that result from the transformation of thyroid follicular cells (anaplastic carcinomas). Notably, 5-10% of all thyroid cancers are medullary thyroid cancers that arise from parafollicular cells also known as C cells. The most common genetic mutations in papillary and follicular thyroid cancers are point mutations of the BRAF or RAS genes, while the most common chromosomal alterations are RET/PTC and PAX8/PPARγ rearrangements...

PURPOSE: Fine-needle aspiration (FNA) cytology is a mainstay in the evaluation of thyroid nodules, but fails to reach reliable results in 25-30% of cases. The role of molecular markers in helping clinical decisions has been investigated for the last years, but their clinical usefulness is still unsettled. METHODS: Mutation analysis of BRAF, RAS genes and TERT promoter was performed in a series of 617 consecutive cytological specimens undergoing FNA. RESULTS: The 617 nodules had the following cytological diagnosis: non diagnostic 22 (3...

CONTEXT: Thyroid nodules with cytological indeterminate results represent a daily and recurrent issue for patient management. OBJECTIVE: The primary aim of our study was to determine if TIRADS (Thyroid Imaging Reporting and Data System) could be used to stratify the malignancy risk of these nodules and to help in their clinical management. Secondary objective was to estimate if this risk stratification would change after reclassification of encapsulated non-invasive follicular variant of papillary carcinomas (FVPTC) as NIFTP...

CONTEXT: - Although fine-needle aspiration (FNA) practice by pathologists is now well established, it has been primarily performed by manual palpation. In recent years, pathologists have begun to venture into ultrasound-guided FNAs (UGFNAs). Reports on experiences with this relatively new technique for pathologists have shown promising results. However to date, there have been few studies in the literature comparing pathologist-performed UGFNA with the more traditional pathologist-performed palpation-guided FNA (PGFNA)...

Background: Thyroid fine needle aspiration (FNA) has a well-established role in the diagnosis of thyroid nodules, and the "Bethesda system for reporting thyroid cytopathology" is used to interpret FNA results. Bethesda categories III and IV encompass varying risks of malignancy. In addition, there is some debate in the literature about how to select among many acceptable treatment approaches. Objectives: To establish an association between these 2 cytological categories and malignancy rates in patients treated in a referral tertiary cancer center, where surgical treatment is recommended for all these patients...

OBJECTIVE: Afirma Gene Expression Classifier® (Afirma GEC® ) molecular analysis (Veracyte, Inc.; San Francisco, CA) is a negative predictive value (NPV) test developed to reduce the number of thyroidectomies in thyroid nodule patients with indeterminate cytology. GEC technology has reportedly reduced unnecessary thyroid surgery, but few studies have examined Afirma GEC false negative rates since usually patients with GEC benign nodules do not undergo surgery for definitive diagnosis...

RATIONALE: There have been many reports of non-thyroidal lesions which can be mistaken for thyroidal lesions on ultrasound (US) examination. However, it is not known that pyriform sinus fistula (PSF) can manifest as an incidental thyroid nodule and cause serious complication on fine-needle aspiration (FNA). PATIENT CONCERNS: We present a 34-year-old man with PSF incidentally detected on US. US examination showed hypoechoic nodule with several bright echogenic spots at the uppermost part of left thyroid gland...
