In the anterior neck, both benign and malignant neoplasms can present, including papillary thyroid carcinoma (PTC), thyroid adenomatoid nodule, parathyroid cysts...

...Miguel Rufail; Xin Jing; Brian Smola; Amer Heider; Richard Cantley; Judy C. Pang; Madelyn Lew Background: Thyroid fine needle aspiration (T-FNA) is a mainstay in management of thyroid nodules. However, the preparation of T-FNA specimens varies across institutions. Prior studies have compared...

... to the diagnosis of thyroid, salivary gland, and other head and neck fine-needle aspiration specimens. Current limitations and potential future applications in diagnosis are discussed along with the possibilities for therapeutic applications of computational methodology. Key Message: Particularly promising...

...José Cândido Caldeira Xavier-Júnior; Felipe Abrantkoski Borges; Rodrigo José Pizzello Zogheib; Deolino João Camilo-Júnior Introduction: Thyroid isthmus is defined as the thin band connecting thyroid tissue between both lateral thyroid lobes. Recently, a possible association between thyroid nodules...

...Dilaver Demirel; Evren Erkul; Suna Erkılıç; Gizem Narlı Issın; Ibrahim Ramzy Background: Primary synovial sarcoma (SS) of the thyroid (PSST) is extremely rare. Its differential diagnosis from other neoplasms is essential since it has different management protocols and prognosis. Case: A 26-year-old...

...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...

...Michiya Nishino; Jeffrey F. Krane Ancillary molecular testing has emerged as a promising way to refine the preoperative risk stratification of thyroid nodules with indeterminate fine needle aspiration (FNA) biopsy results. Commercially available molecular tests for thyroid FNAs include those...

...Céline Melis; Florence Ballaux; Claire Bourgain Background: The most frequent metastases to the thyroid originate in the kidney, lung or breast. Colorectal adenocarcinoma represents less than 4% of metastases to the thyroid gland. Solitary metastases of colorectal cancer with no other manifestation...

...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...

... of clinicopathological findings and clinical management in these cases. Study Design: We included 359 thyroid fine-needle aspiration cytology cases in our study. We reviewed the clinical and cytological features of surgical cases and correlated them with histological diagnosis. We also reviewed the literature...

...Andrew A. Renshaw; Edwin W. Gould 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...

Study Design: A retrospective 6-year audit of 4,532 thyroid fine-needle aspirations (FNA) reported...

... 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...

...Suvi I. Hovi; Ivana Kholová Objective: Fine needle aspiration biopsy (FNAB) can cause reactive histopathological changes, commonly including haemorrhage and granulation tissue. The literature describing vascular proliferation after FNAB is sparse. We aimed to describe neovascularisation in thyroid...

...Jennifer A. Collins; Bo Ping; Justin A. Bishop; Syed Z.
