...Sule Canberk; Diana Montezuma; Umit Ince; Ebru Tastekin; Paula Soares; Massimo Bongiovanni; Fernando C. Schmitt Background: Thyroid cancer accounts for 1% of cancer cases in developed countries, in which papillary thyroid carcinoma (PTC) is the most common type. There are multiple variants of PTC...

...Prerna Guleria; Ravi Phulware; Shipra Agarwal; Deepali Jain; Sandeep R. Mathur; Venkateswaran K. Iyer; Sanjana Ballal; Chandrasekhar S. Bal Objectives: Solid variant of papillary thyroid carcinoma (SVPTC) is rare, differing from classical PTC (cPTC) in architecture and outcome. We evaluated...

...Cristina Díaz del Arco; M. Jesús Fernández Aceñero Objectives: To assess the cytological findings of noninvasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTP), conventional papillary thyroid carcinomas (C-PTC), and invasive follicular variants of papillary thyroid...

...Madelyn Lew; Judy C. Pang; Michael H. Roh; Xin Jing Objective: Malignant effusions due to papillary thyroid carcinoma (PTC) are rare, but portend a poor prognosis. PTC metastases, although rare, most frequently occur in the lungs and bone. Therefore, differentiating thyroid etiology of malignant...

... of undetermined significance Follicular lesion of undetermined significance Thyroid Fine-needle aspiration Papillary thyroid carcinoma Fine-needle aspiration cytology (FNAC) is the most useful diagnostic tool for the preoperative evaluation of thyroid nodules, and the Bethesda System for Reporting...

.... A subsample of cases categorized either as atypia of uncertain significance with nuclear atypia or suspicious for malignancy with features suspicious for papillary thyroid carcinoma. The cytotechnologist and cytopathologist diagnoses were compared using step discrepancies and Δ-ratios. Results: Overall...

...Yoon Yang Jung; In Ae Park; Min A Kim; Hye Sook Min; Jae Kyung Won; Han Suk Ryu Objectives: A panel composed of three immunomarkers, cytokeratin 19, HBME-1 and galectin-3, is recommended for improving the accuracy of diagnosing papillary thyroid carcinoma (PTC), but the results are sometimes...

...Hui Guan; Christopher J. VandenBussche; Yener S. Erozan; Dorothy L. Rosenthal; Armanda D. Tatsas; Matthew T. Olson; Rui Zheng; Manon Auger; Syed Z. Ali Objectives: The tall cell variant of papillary thyroid carcinoma (TCV-PTC) is an aggressive variant of PTC requiring accurate cytopathologic...

... of papillary thyroid carcinoma (PTC) on an LBP exist. We utilized the SurePath LBP system to evaluate conventional and newly recognized cytomorphologic features on histologically confirmed PTC to identify their potent diagnostic significance compared to benign follicular neoplasm (BFN). Study Design: One...

...Soo Young Chung; Jae Seok Lee; Hyebin Lee; Sung Hee Park; Soo Jin Kim; Han Suk Ryu Objective: Preoperative fine needle aspiration biopsy (FNAB) has become the initial diagnostic method for papillary thyroid carcinoma (PTC). Identification of cytomorphologic factors predicting lymph node metastasis...

...Thiraphon Boonyaarunnate; Matthew T. Olson; Justin A. Bishop; Grace C.H. Yang; Syed Z. Ali Background: Cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC) is a rare tumor that may arise in patients with familial adenomatous polyposis (FAP), although sporadic instances of this tumor...

... smears, formalin-fixed paraffin-embedded (FFPE) sections, or NR specimens from 37 patients with confirmed papillary thyroid carcinoma or benign findings. An allele-specific primer selectively amplified the 1799 T>A BRAF mutation while simultaneously blocking amplification of wild-type (WT) BRAF...

...J.C. Ono; D.C. Wilbur; H. Lee; J. Yang; J.F. Krane; M. Bongiovanni; W.C. Faquin Background/Objective: Focal papillary thyroid carcinoma (PTC) arising within a follicular adenoma (PTCFA) represents a clinically significant, but rare, histopathologic subset of papillary carcinomas whose cytologic...

...Jaroslava Dušková; Pavel Tretiník Objective: To analyze reasons for unclear or missed diagnoses in fine needle aspiration biopsy (FNAB) of papillary thyroid carcinoma (PTC). Study Design: Among 35,000 thyroid FNAB diagnoses made during 1989–2009, 135 PTC FNAB diagnoses were divided into 3...

...Ja Seung Koo; Woohee Jung; Soon Won Hong Objective: The purpose of this study is to analyze the characteristic cytologic features of the cribriform-morular variant of papillary thyroid carcinoma (CVPTC) and to find out the possibility of a preoperative diagnosis of CVPTC in fine needle aspiration...
