This commentary summarizes the history and reclassification of noninvasive follicular thyroid neoplasm with papillary-like nuclei (NIFTP). It reviews the salient histopathologic features that are based on immunohistochemical and molecular profiles and serve as inclusion and exclusion criteria. The authors also provide their own point of view regarding the practical issues and possible concerns that may be raised by both clinicians and patients based on the diagnosis of NIFTP. ABBREVIATIONS: AACE = American Association of Clinical Endocrinologists EFVPTC = encapsulated FVPTC FNA = fine-needle aspiration FVPTC = follicular variant of papillary thyroid carcinoma NIFTP = noninvasive follicular thyroid neoplasm with papillary-like nuclear features PTC = papillary thyroid carcinoma...

BACKGROUND: The term "noninvasive follicular thyroid neoplasm with papillary-like nuclear features" (NIFTP) has replaced a subset of follicular variant of papillary thyroid carcinoma due to the indolent behavior of such tumors. NIFTPs are most often classified in an "indeterminate" diagnostic category. In the current study, the authors sought to identify cytologic features helpful in distinguishing NIFTP from other entities in these categories, particularly benign nodules. METHODS: The authors retrospectively evaluated a consecutive cohort of 130 thyroid fine-needle aspiration (FNA) specimens with an indeterminate diagnosis and available histopathologic follow-up...

OBJECTIVE: FNA biopsy is considered as the most accurate method for the selection of patients with thyroid nodules that need for surgery or for the wait and see management. The aim of the present study is to clarify the risk of malignancy for the cytological data classified according to the 2014 Italian reporting system. METHODS: We report a retrospective analysis of 4043 patients in our institution's experience during the period April 2014 through December 2016 with the Italian reporting system for thyroid cytology...

Noninvasive encapsulated follicular variant of papillary thyroid carcinoma (PTC) was reclassified as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). To date, no studies on NIFTP have been reported in Japan. This study aimed to evaluate the clinical, cytological, and pathological findings of 54 cases of NIFTP from a single center in Japan, and compare them with those in the western countries. There were no significant differences in age, sex, or tumor size between patients with NIFTP and those with invasive encapsulated follicular variant -PTC...

BACKGROUND: The reclassification of noninvasive follicular variant of papillary thyroid carcinoma as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) has created diagnostic and management issues for thyroid fine-needle aspiration (FNA). In response to these challenges, the authors' laboratory adopted a NIFTP policy including 1) stringent criteria (requiring pseudo-inclusions, papillae, and/or psammoma bodies) for a malignant diagnosis of papillary carcinoma to limit false-positive results due to NIFTP and 2) the use of explanatory notes in cases with cytomorphologic features suggestive of possible NIFTP to encourage lobectomy over thyroidectomy...

OBJECTIVE: To explore the potential preoperative ultrasonography (US) and cytopathological features to avoid total thyroidectomy in NIFTP CONTEXT: Recently, it has been proposed that that non-invasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTP) be classified as tumors, rather than cancer. PATIENTS: A total of 142 surgically proven follicular variant papillary thyroid carcinomas (FVPTCs; 45 NIFTP, 97 non-NIFTP; mean size: 20.4±11.0 mm, range: 10...

Anaplastic Thyroid Carcinoma (ATC) is a relatively uncommon highly malignant tumour originating from the follicular cells of thyroid gland having poor prognosis. It accounts for 2% to 5% of all thyroid carcinomas and patients typically present with a rapidly growing anterior neck mass with aggressive symptoms. A 53-year-old male presented with diffuse neck swelling measuring 8x6 cm and right cervical lymph node measuring 2x2 cm since one month which was associated with dyspepsia and dyspnoea. Ultrasound and Contrast Enhanced Computed Tomography (CECT) neck revealed enlarged right lobe of thyroid and multiple enlarged cervical lymph nodes with soft tissue density nodules in bilateral lungs...

Objective Neck masses are common in adults, but often the underlying etiology is not easily identifiable. While infections cause most of the neck masses in children, most persistent neck masses in adults are neoplasms. Malignant neoplasms far exceed any other etiology of adult neck mass. Importantly, an asymptomatic neck mass may be the initial or only clinically apparent manifestation of head and neck cancer, such as squamous cell carcinoma (HNSCC), lymphoma, thyroid, or salivary gland cancer. Evidence suggests that a neck mass in the adult patient should be considered malignant until proven otherwise...

Pheochromocytomas are catecholamine-secreting neoplasms, arising from adrenomedullary chromaffin cells. In type 2 multiple endocrine neoplasia (MEN2) syndrome, pheochromocytomas are usually benign but with predisposition to be bilateral (50%-80% of cases).The authors present the case of a young patient diagnosed with uncommonly large bilateral cystic pheochromocytomas and simultaneous detection of medullary thyroid carcinoma. Molecular testing confirmed germline RET codon C634 mutation, consistent with MEN2A syndrome...

Thyroid nodules represent heterogeneous tumors with distinct molecular signatures. While benign thyroid nodules correspond to poly- or monoclonal tumors, thyroid carcinomas are monoclonal and thus "real" neoplasms. These are caused by somatic mutations that lead to the constitutive activation of specific signaling cascades and determine the corresponding histology and also partly the functional phenotype of the thyroid tumor. Dedifferentiation of thyroid carcinomas is accompanied by the occurrence of additional mutations in the tumors...

Squamous cell carcinoma is an extremely rare neoplasm of the thyroid (SCTC) that represents no more than 1% of all primary thyroid malignancies. We report a case of a 42-year-old woman with rapidly growing mass in the right lower neck, primarily diagnosed in fine-needle aspiration cytology as a low-differentiated carcinoma. After the surgery, exclusion of all the other possible primary tumour locations, and immunohistochemistry tests, the diagnosis of primary squamous cell carcinoma of the thyroid gland was established...

BACKGROUND: Due to the recent proposal of the non-invasive follicular thyroid neoplasm with papillary-like nuclear feature (NIFTP) category, the authors analyse the state of the art in the challenging diagnosis of follicular thyroid neoplasms in routine practice. METHODS AND RESULTS: A consecutive series of 200 histological diagnoses, with complete cytological correlation, was analysed following the introduction of the NIFTP definition. The study was conducted in a general hospital with a high prevalence of thyroid benign nodules that accounted for approximately 60% of surgically-treated nodules...

Theranostics, a modern approach combining therapeutics and diagnostics, is among the most promising concepts in nuclear medicine for optimizing and individualizing treatments for many cancer entities. Theranostics has been used in clinical routines in nuclear medicine for more than 60 y-as (131)I for diagnostic and therapeutic purposes in thyroid diseases. In this minireview, we provide a survey of the use of 2 different radioiodine isotopes for targeting the sodium-iodine symporter in thyroid cancer and nonthyroidal neoplasms as well as a brief summary of theranostics for neuroendocrine neoplasms and metastatic castration-refractory prostate cancer...

Current thyroid molecular tests are specifically designed for the differential diagnosis of nodules with indeterminate or suspicious fine needle aspiration (FNA) cytology. However, their clinical validity faces challenges from both variation among institutions in cancer prevalence and, most recently, the new category of non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFT-P). The latter diagnosis was previously classified as malignant. Relevant to this, all molecular panels on the market today were originally tested and validated within the context of these entities being considered malignant...

AIMS AND BACKGROUND: Thyroid transcription factor-1 (TTF-1) expression is widely considered a specific marker for lung and thyroid carcinomas and plays an important role in angiogenesis in lung cancer. However, it can occasionally be expressed in other malignancies, including ovarian carcinomas, and the mechanism of TTF-1 in lymphatic metastasis of ovarian carcinomas is still unclear. This study aimed to define the TTF-1 expression and lymph vessel density (LVD) in ovarian carcinomas and look for their correlations with clinicopathological features...

PURPOSE: In the management of thyroid nodules, although the potential for malignancy exists, there is also the potential for overtreatment of subclinical disease. Although the TI-RADS (Thyroid Imaging-Reporting and Data System) system outlines a risk stratification score based on suspicious ultrasound findings, it has not been universally accepted. Many TI-RADS 2 or 3 patients proceed to fine needle aspiration biopsy (FNAB), potentially unnecessarily. The aim of the study was to identify whether lesions within a multinodular goiter (MNG) without suspicious features can be followed with ultrasound rather than biopsied as is recommended for single nodules...

BACKGROUND: A major reclassification occurred with the redesignation of noninvasive encapsulated follicular variant of papillary thyroid carcinoma as noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) due to its indolent nature. The aim of this study was to determine whether distinct cytomorphologic features could be identified on preoperative fine-needle aspiration (FNA) when NIFTP cases were compared with invasive follicular variant of papillary thyroid carcinoma (FVPTC) subtypes...
