BACKGROUND: Noninvasive encapsulated follicular variant of papillary thyroid carcinoma, a diagnosis implying malignancy as a variant of papillary thyroid carcinoma (PTC), has recently been reclassified to noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) on surgical pathology. Due to the effects of such a recategorization on rate of malignancy and clinical management algorithms, it is imperative that we explore whether presurgical fine-needle aspiration can differentiate NIFTP from PTC and follicular adenoma (FA)...

BACKGROUND: With the increased use of whole body fluorodeoxyglucose positron emission tomography (PET) scan for staging/restaging or primary diagnosis of neoplasia, thyroid incidentalomas have become more common. The limited reports of PET-positive thyroid incidentalomas showed incidence of malignancy ranging from 14 to 66%, and there is discrepancy in terms of the diagnostic significance of the standard uptake value (SUV) value. METHODS: This is a retrospective study of 20 PET incidentalomas which had cytological evaluation from October 2009 to February 2015 at a tertiary care university medical center, M:F = 8:12...

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...

Thyroid cancer is common type of malignant tumor in humans, and the autophagy status of such tumors may vary according to subtype. This study aimed to investigate the expression and implications of the major autophagy-related molecules light chain (LC) 3A, LC3B, p62, and BNIP-3 in human thyroid carcinoma. Tissue microarrays were constructed from 555 thyroid cancers (papillary thyroid carcinoma (PTC): 342; follicular carcinoma (FC): 112; medullary carcinoma (MC): 70; poorly differentiated carcinoma (PDC): 23; and anaplastic carcinoma (AC): 8) and 152 follicular adenomas (FAs)...

BACKGROUND: Fine needle cytology (FNC) of a parathyroid neoplasia (PN) is reliable, but needs to be confirmed by Parathormone (PTH) and Thyroglobulin (TG) immunoassay on needle washing or by immunocytochemistry (ICC) evaluation. The differentiation between parathyroid adenoma (PA), atypical adenoma (PAA) and carcinoma (PC) is difficult on histology or even impossible on FNC. The aim of this study was to evaluate possible cytological criteria to classify FNC-PN further. METHODS: Twenty-three FNC samples of PN and parathyroid cysts were rather then have been reviewed...

BACKGROUND: Papillary Thyroid Carcinoma (PTC) is the most common type of malignant thyroid tumors. The main diagnostic clue of PTC is the presence of its characteristic nuclear features. Yet, the focal presence of these features in other thyroid lesions causes a diagnostic dilemma. AIM: To evaluate Cytokeratin 19 (CK19) and CD56 immunostains as useful diagnostic markers in distinguishing papillary thyroid carcinoma from other mimicking thyroid lesions. METHODS: Eighty cases of different thyroid lesions were submitted for immunohistochemical staining of CK19 and CD56...

BACKGROUND: The Afirma gene expression classifier (GEC) is being increasingly utilized to confirm the benign nature of indeterminate FNA cytology results thus avoiding unnecessary surgical procedures. However the "suspicious" result of the Afirma GEC does not classify these indeterminate nodules further in determining appropriate management. This study investigated the outcome of the thyroid nodules deemed to be "suspicious" by the Afirma GEC in a high risk population. METHODS: The pathology database was searched for all thyroid nodules with Afirma test results over a three year period, 2013-2015...

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...

BRAF mutations represent the most common genetic alteration in papillary thyroid carcinoma (PTC). The p.V600E mutation is specific for the classic and tall-cell variants of PTC and has been associated with a more aggressive biologic behavior. On the other hand, the p.K601E mutation is peculiar to the follicular variant of PTC, and seems to be a favorable prognostic indicator. A 12-year-old boy presented with a 10-mm left-sided thyroid nodule. Fine-needle aspiration cytology reported the lesion as suspicious for a follicular neoplasm (Bethesda category IV)...

Recently, the immunohistochemistry (IHC) for N-RAS Q61R has been developed and commercialized for clinical practice. Here, we investigated the reliability of IHC to identify N-RAS Q61R mutated thyroid neoplasia. A series of 24 consecutive thyroid lesions undergone surgery following indeterminate cytology were enrolled. Paraffin sections were stained for IHC using the rabbit monoclonal anti-human N-RAS Q61R, clone SP174. N-RAS mutations in codon 61 were also investigated by automated sequencing. At histology, 12 cases of follicular carcinoma, cytologically defined as follicular lesions, 1 papillary cancer, 7 follicular adenomas, and 4 hyperplastic nodules were found...

INTRODUCTION: Thyroid cancer (TC), follicular adenoma (FA) and Hashimoto's thyroiditis (HT) are three of the most frequently reported abnormalities that affect the thyroid gland. A frequent co-occurrence along with similar histopathological features is observed between TC and FA as well as between TC and HT. The conventional diagnostic methods such as histochemical analysis present complications in differential diagnosis when these abnormalities occur simultaneously. Hence, the authors recognize novel methods based on screening genetic defects of thyroid abnormalities as viable diagnostic and prognostic methods that could complement the conventional methods...

Water-clear cell adenoma (WCCA) of the parathyroid gland is an exceedingly rare neoplasm. To date, 17 cases have been reported in the literature, with only one of them being intrathyroidal. Here we report a case of a 34-year-old woman who presented for evaluation of a goiter and was found to have a thyroid nodule and abnormal thyroid function tests (TFT). Fine needle aspiration biopsy of the nodule revealed thyroid follicular cells without atypia and subsequent Afirma® Gene Expression Classifier (GEC) testing results were suspicious for malignancy...

The prostate-specific membrane antigen (PSMA) is expressed by both prostate cancer and other neoplasms. We report the case of a 65-year-old man with castration-resistant metastatic prostate cancer who underwent Ga-PSMA ligand PET/CT for restaging of disease. Ga-PSMA ligand accumulation was noted in a thyroid lesion, suspicious for thyroid malignancy on complementary ultrasound. Subsequent resection and histopathological analysis showed follicular thyroid adenoma with PSMA expression in tumor neovasculature endothelial cells, but not in thyroid epithelial cells...

BACKGROUND: Follicular thyroid cancer is the second most common thyroid cancer, accounting for 10%-15% of all cases. Follicular thyroid carcinomas (FTCs) can be classified into two subtypes: classic (C), which exhibit both vascular and capsular invasion and minimally invasive (MI), which only has limited capsular invasion. Both types, like most well-differentiated thyroid cancers, are traditionally treated the same: a completion thyroidectomy usually followed by radioiodine ablation. We hypothesize that MI-FTC may behave more like a benign follicular adenoma rather than C-FTC and may not require total thyroidectomy and radioiodine...

Thyroid carcinoma (TC) is the most common endocrine cancer and its incidence has been increasing globally over the past decades. With the development of the genetic technology, more and more evidences showed that many genes affect the biological behaviors of TC, making sense to early diagnosis, predicting the prognosis and targeted therapy for TC. BRAF mutation is specific to papillary thyroid carcinoma (PTC). It can not only predict the prognosis, but also have diagnosis value. RET rearrangements are identified as a specific genetic event in PTC...
