Afsin Rahman Murtezaoglu, Hasan Gucer
In this study, we compared the diagnostic value of TROP-2 expression in distinguishing between benign and malignant thyroid lesions to those of HBME-1, CK19 and galectin-3. We selected 102 cases from our archive including 20 normal thyroid tissues, 23 follicular nodular diseases, 17 follicular adenomas, 20 follicular variant papillary carcinomas and 22 classical variant papillary carcinomas. Tissue microarrays constructed from these cases were immunohistochemically analyzed with HBME-1, CK19, galectin-3 and TROP-2...

FoxA1 regulates a variety of tissues during embryogenesis and early life. In thyroid, FoxA1 expression has recently been shown in C cells and medullary thyroid carcinomas but not in follicular cells. FoxA1 has also been proposed as potential oncogene in anaplastic thyroid carcinomas. However, FoxA1 expression has not been extensively investigated in a spectrum of thyroid non-neoplastic lesions and tumors. A variety of thyroid tumors and lesions and their morphologic mimics were stained with monoclonal anti-FoxA1 antibody...

BACKGROUND: A recent revision in thyroid tumor nomenclature has resulted in a change from a malignant diagnosis (noninvasive follicular variant of papillary thyroid carcinoma) to one that is nonmalignant (noninvasive follicular thyroid neoplasm with papillary-like nuclear features [NIFTP]). The objective of the current study was to evaluate the impact of this change on the performance of the Afirma gene expression classifier (GEC). METHODS: The authors retrospectively analyzed consecutive thyroid fine-needle aspiration specimens with indeterminate diagnoses on which GEC was performed...

Atypical adenoma of the thyroid is a rare form of tumor, and its accurate diagnosis prior to surgical resection is difficult as the histological and pathological morphologies are very similar to those of anaplastic thyroid carcinoma (ATC), and its anaplastic transformation remains to be elucidated. We reported a case of a 75-year-old female with a thyroid isthmus nodule diagnosed repeatedly by FNAC as anaplastic carcinoma. Both the first and second FNAC specimen slides showed a large number of scattered or aggregated atypical cells consisting of large, pleomorphic nuclei with irregular membranes, chromatin clumps and prominent nucleoli...

MicroRNA (miRNA) are negative regulators of gene expression and subsequent protein production. This method of action translates into regulatory control over cellular processes, including development, signaling, metabolism, and apoptosis. A broad range of miRNA are shown to have abnormal expressions in thyroid cancers which could explain the pathology of tumor oncogenesis and disease progression. A review is conducted of the current research on miRNA dysregulation in thyroid cancers, including papillary thyroid carcinoma (PTC), follicular thyroid carcinoma (FTC), anaplastic thyroid cancer (ATC), and medullary thyroid carcinoma (MTC)...

Thyroglossal duct cysts (TGDCs) are present in ~7% of adults and develop from the midline migratory tract between the foramen cecum and anatomic location of the thyroid. Thyroid tissue can be identified in 2/3 of TGDCs, and up to 1% develop associated malignancy, 90% of which are papillary thyroid carcinoma. Cases of follicular and anaplastic carcinoma have been documented, but there are no reports of medullary thyroid carcinoma arising in a TGDC. This is presumably due to the distinct embryologic origin of parafollicular C-cells, from which medullary carcinoma arises...

The distinction of thyroid carcinoma from benign thyroid neoplasm, as well as the subtyping of papillary carcinoma (PC) and follicular carcinoma (FC), may be performed histopathologically in the majority of cases. However, in certain cases, it is difficult to histopathologically distinguish between PC and FC, as well as follicular adenoma (FA), FC and the dominant nodule of multinodular goiter (MNG-DN). The present study aimed to determine the roles of the expression levels of the tight junction proteins claudin 1, 4 and 7 in the differential diagnosis of PC, FC, FA, MNG-DN, medullary carcinoma (MC) and anaplastic carcinoma (AC)...

The tall cell variant (TCV) of papillary thyroid carcinoma (PTC) is characterized by tall columnar cells with a height of at least three times their width. TCV usually presents at an older age, has a larger size and exhibits more extrathyroidal extension and metastases than classical PTC. The current study compared TCV with the classical and follicular variants (CaFVs) of PTC to determine if, irrespective of the age at diagnosis and tumor size, TCV is more aggressive than its classical and follicular counterparts...

BACKGROUND: A transoral approach has been experimentally introduced to the field of thyroid surgery and several groups in Asia have recently used the technique to treat patients. We performed transoral endoscopic thyroidectomies on patients with thyroid cancer or a benign tumor. METHODS: We reviewed the medical records of patients who underwent transoral endoscopic thyroid surgery between July 2016 and January 2017. A midline incision was made in the vestibule, and a 10 mm cannula was placed; then, the working space was widened by insufflating CO2 at a pressure of 5-6 mmHg...

The expression of non-metastatic expressed/non-metastatic 23 nucleoside diphosphate kinase 1 (nm23-H1) and cyclooxygenase 2 (COX-2) proteins in thyroid carcinoma have been analysed in a number of previous studies, but this requires further study. The current study focused on the expression levels of nm23-H1 and COX-2 in 130 human thyroid papillary carcinoma (PTC) tissues. Of the 130 PTC tissues, 55 were classified as microcarcinoma and may provide information on the development of the specific characteristics of this tumour type...

A 61-year-old woman noticed a right neck lump in October 2001. Fine needle aspiration showed follicular neoplasm, adenoma versus carcinoma. The ultrasound scan showed a solid mass of maximum dimension of 3.7 cm. She had a right thyroid lobectomy and isthmectomy in January 2002 (first surgery). The tissue specimen showed a 4.5 cm Hurthle cell carcinoma (HCC) with vascular invasion. There were no capsular invasion, extra-thyroidal extension, or margin involvement. A completion left lobectomy (second surgery) was performed two weeks later...

BACKGROUND: The aberrant activation of Wnt signalling pathway may be a common denominator for the development of thyroid tumorigenesis. It was announced that the loss of E-cadherin rather than β-catenin mutation represents a crucial event in determining the degree of differentiation of thyroid carcinomas. AIM: The aim of the study was to evaluate the expression of E-cadherin and β-catenin in the thyroid cancer tissue and to correlate these data with some histological and clinical parameters of the tumours...

BACKGROUND: The diagnosis of thyroid nodular diseases requires an integrated approach that has been widely established over the past years. This strategy includes: ultrasonography (US) with; implemented Color-Power-Doppler, conventional scintigraphy also with positive indicators, specific pathological studies targeted by immunohistochemically-assays, and the fine needle; aspiration biopsy (FNAB), which, usually, in case of "Follicular Lesions" (10-20%) findings is; unable to distinguish carcinoma from follicular adenoma, then indicating the necessity of surgery to; obtain a correct diagnosis...

A 51-year-oldwoman with a right renal mass was referredto our hospital. Computedtomographic (CT) scan demonstrated a 30 mm-diameter renal mass with delayed enhancement. She underwent a robotassistedlaparoscopic right partial nephrectomy. The pathological examination showedthat tumor cells with eosinophilic, clear cytoplasm formedtubules of various sizes containing colloid-like material, which resembled the findings of thyroidfollicular carcinoma. The tumor was immunoreactive for vimentin andcytokeratin (CK) 7, whereas it lackedreactivity for thyroidtranscription factor-1 (TTF-1) or thyroglobulin...

71-year-old woman was pointed out to have an asymptomatic mediastinal tumor. Chest computed tomography(CT) showed a well-demarcated mass measuring 7 cm in diameter in the anterior mediastinum. We resected the mass through a median sternotomy. The tumor had a clear margin without invasion to the surrounding tissue and did not show continuity with the cervical thyroid gland. Histopathologically, the tumor was diagnosed as follicular thyroid carcinoma with capsular invasion. This is an exceptionally rare case.

BACKGROUND/AIMS: In mammalian cells, XRCC3 plays an important role in the DNA double-strand breaks (DSBs) repair by homologous recombination. Genetic polymorphisms in XRCC3 gene may potentially affect the repair of DSBs and thus confer susceptibility to thyroid cancer. In this study, we used a haplotype-based approach to investigate whether 5 selected SNPs i.e. rs1799796, rs1799794, rs861539, rs709399 and rs861530 of XRCC3 gene are associated with thyroid cancer risk in 456 cancer patients and 400 cancer-free controls...

Reclassification of non-invasive encapsulated follicular variant of papillary thyroid carcinoma (EFV-PTC) into non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) has significant impact for patients and clinicians. It was estimated that this reclassification could potentially affect more than 45,000 patients worldwide annually (around 20% of thyroid carcinoma), who will not be labeled as having cancer. Our experience from Asian grounds indicates that NIFTP is extremely rare in local practice...

INTRODUCTION: Whether true papillae without nuclear features of papillary carcinoma in thyroid fine needle aspirates should be diagnosed as atypia of undetermined significance (AUS) is unclear. METHODS: The results of all thyroid FNAs performed from 2014-2016 with corresponding resections as well as aspirates from 2000-2016 with a diagnosis of follicular variant of papillary carcinoma or Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) were reviewed...
