The Bethesda System for Reporting Thyroid Cytology (TBSRTC) was proposed in 2007 at the National Cancer Institute Thyroid Fine Needle Aspiration State of the Art and Science Conference held in Bethesda, Maryland. The aim was to address the inconsistent and sometimes confusing reporting terminologies used for thyroid FNA throughout the world. The TBSRTC consists of 6 diagnostic categories, each associated with an implied risk of malignancy that translates directly into a clinical management algorithm. Since the publication of the TBSRTC cytology Atlas in January 2010, considerable experience has been gained regarding its application in cytology practice, clinical impact, and limitations...

PURPOSE: The aim of this study was to elucidate the cytological characteristics and the diagnostic usefulness of intraoperative cytology (IOC) for papillary thyroid carcinoma (PTC). In addition, using decision tree analysis, effective features for accurate cytological diagnosis were sought. METHODS: We investigated cellularity, cytological features and diagnosis based on the Bethesda System for Reporting Thyroid Cytopathology in IOC of 240 conventional PTCs. The cytological features were evaluated in terms of nuclear score with nuclear features, and additional figures such as presence of swirling sheets, psammoma bodies, and multinucleated giant cells...

CONTEXT: -Fine-needle aspiration (FNA) biopsies have been an important component in the preoperative evaluation of thyroid nodules. Until the introduction of the Bethesda System for Reporting Thyroid Cytopathology (BSRTC) in 2008, individual institutions had developed their own diagnostic categories. The BSRTC proposed 6 categories in an attempt to standardize reporting of thyroid FNA. OBJECTIVE: -To present a 15-year experience of thyroid FNA at one institution, including data before and after introduction of the BSRTC...

BACKGROUND: The utility of frozen section (FS) for indeterminate thyroid nodules is controversial. In 2009, the Bethesda System for Reporting Thyroid Cytopathology was established to further subcategorize indeterminate fine-needle aspiration results (follicular lesions, FL) into Bethesda category 3 (BC3) and Bethesda category 4 (BC4). We hypothesize that FS will have less utility in the evaluation of BC3 lesions when compared to BC4. MATERIALS AND METHODS: A total of 479 patients who underwent thyroid lobectomy from January 2008 to July 2014 were retrospectively reviewed...

BACKGROUND: CASTLE (carcinoma showing thymus-like differentiation) is a rare tumor (accounting for less than 0.15% of thyroid neoplasms) with most of the reported cases from Asia. Although this tumor is rare, distinguishing it from more aggressive neoplasms is critical because of its improved prognosis. To date, there have been limited studies on its cytomorphological features. Herein, we review the cytomorphological features of 10 fine-needle aspiration (FNA) cases of histologically confirmed CASTLE and discuss the findings in light of the current literature...

Mammary analog secretory carcinoma (MASC) is a recently described rare neoplasm that was first reported in the salivary gland with an associated ETV6-NTRK3 fusion. We present a case of MASC involving and presumably arising in the thyroid, which was originally diagnosed as papillary thyroid carcinoma on fine needle aspiration and surgical resection. The later correct diagnosis of MASC was confirmed by immunohistochemistry and molecular studies. The cytopathological features of MASC in the salivary gland are previously described; however, we present the first cytopathological description of MASC arising in the thyroid with the unique feature of prominent nuclear grooves...

BACKGROUND: Only a small number of studies on computerized cytomorphometry have been performed for thyroid FNAC. The present study aimed to determine the usefulness of computerized cytomorphometry methods to further classify thyroid lesions as benign or malignant and to compare the practicability and value of using Papanicolaou (Pap) and Giemsa stains in thyroid FNAC by evaluating their association to various cytologic nuclear parameters. METHODS: Fifty-eight thyroid lesions diagnosed by FNAC and categorized according to the Bethesda system for reporting thyroid cytopathology were evaluated in terms of various cytologic nuclear parameters, including nuclear area (NA), nuclear perimeter (NP), nuclear density (ND), long nuclear diameter (LND), and short nuclear diameter (SND)...

Indeterminate thyroid nodules include heterogeneous lesions that could benefit from a differential management. Our aim is to better define the management of the Bethesda System for Reporting Thyroid Cytopathology class III and IV nodules, by identifying cytological subcategories among Bethesda System for Reporting Thyroid Cytopathology class III associated with different clinical risk, by means of ultrasound, repeated FNAB, and BRAFV600E molecular analysis. We also evaluated the outcome of nodules not operated, over a 5-year follow-up...

BACKGROUND: Thyroid nodules are commonly encountered problems in clinical practice. For patients who have a thyroid nodule, the fine-needle aspiration biopsy (FNAB) is the most important test, as it is the most reliable diagnostic method for distinguishing between benign thyroid nodules and cancerous nodules. FNAB is able to be performed either via an ultrasound (USG) or alone and is the first choice when it comes to diagnosing thyroid nodules, given that it is cheap, safe and provides accurate results...

Oxyphilic cell carcinoma is a relatively rare type of differentiated thyroid carcinoma. We investigated the diagnosis of oxyphilic cell carcinoma based on surgical specimens and cytology to elucidate the indications for surgery for oxyphilic tumors. Among 330 patients pathologically diagnosed as having an oxyphilic cell carcinoma or adenoma, the incidence of carcinoma was 21%. The pathological diagnosis of oxyphilic cell carcinoma was related to tumor size (>4 cm). On cytology, 79% of the tumors were classified as category IV or greater by the Bethesda System for Reporting Thyroid Cytopathology (BSRTC), but no significant difference was established between category IV or greater and categories I-III regarding the incidence of carcinoma...

Background. Midkine (MK), a new heparin-binding growth factor, plays important roles in a variety of biological phenomena such as carcinogenesis, inflammation, and angiogenesis. In this study, we aimed to evaluate serum midkine (SMK) and nodular midkine (NMK) levels in patients with thyroid nodules to predict malignancy and whether there was any association between. Methods. A total of 105 patients (74 women, 31 men) with thyroid nodules were enrolled. The levels of SMK and NMK were measured. Any possible correlation between SMK, NMK, and biochemical, cytopathological, or radiological variables was investigated...

Thyroid nodules are a very common problem. Since malignant thyroid nodules should be treated surgically, preoperative diagnosis of thyroid cancer is very crucial. Cytopathologic analysis of percutaneous fine-needle aspiration (FNA) specimens is the current gold standard for diagnosing thyroid nodules. However, this method has led to high rates of inconclusive results. Metabolomics has emerged as a useful tool in medical fields and shown great potential in diagnosing various cancers. Here, we evaluated the potential of nuclear magnetic resonance (NMR) analysis of percutaneous FNA specimens for preoperative diagnosis of thyroid cancer...
