Variants of papillary thyroid carcinoma (PTC) account for up to 25% of the cases, some of which are proven to be associated with aggressive clinical behavior such as tall cell and columnar cell variants. Hobnail variant of PTC (HVPTC) is recently described as a rare and aggressive variant of PTC. Herein, we are reporting a case of HVPTC in a patient who presented with hemoptysis and an intratracheal blood clot that was aspirated and submitted for cytopathological examination. Cytomorphology displayed neoplastic cells with profound micropapillary architecture, elongated nuclei, and prominent hobnail configuration...

The aim of this study was to present our experiences with patients operated on for the recurrence of papillary thyroid cancer with the combined use of preoperative ultrasonographic mapping and radioguided occult lesion localization (ROLL). Twenty patients who had already undergone total thyroidectomy and central/lateral neck dissection for papillary thyroid carcinoma were reoperated on due to locoregional metastasis. The patients with proven recurrences and high Tg wash-out levels in cytopathologic aspirates were operated on...

REVIEW
Marta Wesoła, Michał Jeleń
Fine needle aspiration (FNA) biopsy is an important and widely accepted method used in the diagnosis of patients with thyroid nodules.The lack of consistency in reporting FNA taken from the thyroid gland has led to divergences in the calculation of the sensitivity and specificity of the method. Discrepancies depend on what was considered to be true or false negative/positive. This resulted in confusion among doctors, who had to decide how to manage the patient with constantly changing positive or negative results of the FNA...

BACKGROUND: Adequacy criteria for thyroid fine-needle aspiration (FNA) recommended by The Bethesda System for Reporting Thyroid Cytopathology (TBS) were developed with smears, but they are commonly applied to ThinPreps (TPs). This study evaluated adequacy in TPs at different diagnostic thresholds. METHODS: All FNA procedures performed between 2010 and 2015 with matched surgical specimens were analyzed. Cell counts and cytological features were evaluated in all initially nondiagnostic (ND) cases...

BACKGROUND: Thyroid nodules are common and often benign, although prove to be malignant upon surgical pathology in 5-15% of cases. When assessed with ultrasound-guided fine-needle aspiration (USFNA), 15-30% of the nodules yield an indeterminate result. The Afirma® gene expression classifier (AGEC) was developed to improve management of indeterminate thyroid nodules (ITNs) by classifying them as "benign" or "suspicious." Objectives were (1) to assess the performance of the AGEC in two Canadian academic medical centres (2), to search for inter-institutional variation and (3) to compare AGEC performance in Canadian versus American institutions...

Thyroid incidentaloma is defined as an unsuspected, asymptomatic thyroid lesion that is discovered on an imaging study or during an operation unrelated to the thyroid gland. We aim to evaluate the relationship between overweight or obese and risk of malignancy in patients with thyroid incidentaloma detected by F18-flurodeoxyglucose positron emission tomography/computed tomography and factors to predict risk of malignancy in thyroid incidentaloma. From January 2010 to December 2013, a total of 238 patients were eligible for this study...

Background. Fine needle aspiration (FNA) remains the first-line diagnostic in management of thyroid nodules and reduces unnecessary surgeries. However, it is still challenging since cytological results are not always straightforward. This study aimed to examine the results of thyroid FNA using the Bethesda system for reporting thyroid cytopathology (TBSRTC) to establish the level of accuracy of FNA procedures in a rural practice setting. Method. A retrospective chart review was conducted on existing thyroid FNA performed in a referral endocrine center between December 2011 and November 2015...

OBJECTIVE: Cytopathologic interpretation in Graves disease (GD) is considered challenging due to significant cellular atypia. STUDY DESIGN: We retrospectively identified 55 fine needle aspirations (FNAs) from 43 patients with GD that subsequently underwent thyroidectomy from 1995 to 2016. RESULTS: There were 5 patients with papillary thyroid carcinoma (PTC) and 4 with follicular adenoma (FA). Of the 5 patients with PTC, FNA was interpreted as PTC in 3, atypia of undetermined significance (AUS) in 1, and adenomatoid nodule (AN) in 1 (with a 0...

BACKGROUND: The noninvasive follicular variant of papillary thyroid carcinoma (PTC) has an indolent clinical behavior in comparison with other PTCs, including the invasive follicular variant of papillary thyroid carcinoma (IFVPTC). Recently, the term noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) was introduced to emphasize the low biological potential of these tumors. This study compares clinical, cytological, and molecular features of NIFTP and IFVPTC...

BACKGROUND: The Bethesda System for Reporting Thyroid Cytopathology is the most widely used classification system for the reporting of thyroid fine-needle aspiration cytology (FNAC) specimens. However, the "atypical" category ("atypia of undetermined significance" [AUS] or "follicular lesion of undetermined significance" [FLUS]) continues to cause diagnostic and therapeutic dilemmas. The objectives of this study were to describe the differential malignancy rates of FNACs diagnosed as AUS/FLUS based on nuclear or architectural atypia and to assess the significance of demographic and ultrasonographic features in predicting malignancy in this category...

INTRODUCTION: Although cytology and histopathology of thyroid lesions generally fall into common, well-defined categories, there are uncommon cases with unusual fine needle aspiration (FNA) findings or histology. Herein, we review the prevalence and characteristics of rare thyroid cytology and histopathology findings at a tertiary hospital. METHODS: Institutional data from >31,000 patients with a thyroid pathology from 1995 to 2013 were queried. Both cytology and histology were available in 6,693 patients...

BACKGROUND: Thyroid nodules with atypia of undetermined significance (AUS) on fine-needle aspiration (FNA) have a low risk of malignancy that appears to vary based on specific features described in the AUS diagnosis. The Afirma gene expression classifier (GEC) is a molecular test designed to improve preoperative risk stratification of thyroid nodules, but its performance for different patterns of AUS has not been defined. The objective of this study was to assess GEC results and clinical outcomes in AUS nodules with architectural atypia (AUS-A), cytologic atypia (AUS-C) or both (AUS-C/A)...

BACKGROUND: Fine-needle aspiration (FNA) of the thyroid gland has proven to be an important and widely accepted, cost-effective, simple, safe, and accurate method triaging patients with thyroid nodules. Awareness and understanding of wide spectrum thyroid disorders are of great value because most lesions are treatable by medical or surgical management. AIM: The aim of this study is to determine the accuracy of FNA cytology (FNAC) in the diagnosis of thyroid lesion using the Bethesda system for reporting thyroid cytopathology nomenclature (BSRTC) and to correlate these with histopathological findings...

OBJECTIVES: Current preoperative diagnosis of thyroid nodules remains imperfect despite recent advances in cytopathology and molecular diagnostics. False positivity in preoperative fine-needle aspiration cytology (FNAC) may lead to overtreatment of patients, including total thyroidectomy, and sometimes to lawsuits for misdiagnosis and malpractice. In this study, we analysed clinical characteristics and pathologic findings in patients with false positivity for papillary thyroid carcinoma (PTC) in FNAC...
