Context: Although 60% of papillary thyroid carcinomas are BRAFV600E mutant (PTCV600E), the higher aggressiveness of these cancers is still debated. Objective: In PTCV600E we aimed to further characterize the extent of the stroma and its activation, the 3D tumor-stroma interface, and the proliferation rates of tumor and stromal fibroblasts. Design: We analyzed exomes, trancriptomes and images of 364 PTC from The Cancer Genome Atlas (TCGA), including 211 PTCV600E; stained 22 independent PTC for BRAFV600E and Ki67; sequenced the exomes and stained BRAFV600E in 5 primary tumor blocks and 4 nodal metastases from one PTCV600E patient; and reconstructed the 3D volumes of one tumor and one metastatic blocks at histological resolution...

Mesenchymal neoplasms rarely present in or adjacent to endocrine organs. In this context, the recognition of these rare tumor types can be challenging, with significant potential for misdiagnosis as sarcomatoid carcinomas (i.e., anaplastic thyroid carcinoma and sarcomatoid adrenal cortical carcinoma) or neuroendocrine carcinomas, depending upon the dominant histologic patterns. In this review, we address potential pitfalls in diagnosing selected mesenchymal neoplasms arising within or near endocrine organs, including dedifferentiated liposarcoma, synovial sarcoma, angiosarcoma, PEComa, proximal-type epithelioid sarcoma, Ewing sarcoma, and neuroblastoma...

Whether the initiating time of radioiodine (RAI) therapy will affect the clinical outcome in differentiated thyroid cancer (DTC) remains controversial. The objective of this study was to evaluate the impact of RAI therapy initiating time on response to initial therapy in low- to intermediate-risk DTC METHODS: A total of 235 consecutive patients with low- to intermediate-risk DTC were retrospectively reviewed. According to the time interval between thyroidectomy and RAI therapy, patients were divided into Group 1 (interval < 3 months, n=187) and Group 2 (interval ≥ 3 months, n=48)...

BACKGROUND: Small tumor diagnostic tools including ultrasound-guided fine needle aspiration (FNA) and computed tomography (CT) could be causing rising and racially/ethnically different thyroid cancer incidence rates due to variable overdiagnosis of indolent tumors. Papillary tumors and <40 mm tumors are most likely to be overdiagnosed as indolent tumors by FNA and CT. METHODS: Age-adjusted incidence rates (AAIRs) for the years 2007-2014 were calculated for race/ethnicity (white, Hispanic, Asian, African American, Native American) by patient/tumor characteristics for microscopically confirmed malignant thyroid cancer cases in the Surveillance, Epidemiology, and End Results Program 18 database (SEER 18; N = 93,607)...

Anaplastic thyroid cancer (ATC) constitutes less than 2% of total thyroid cancers but accounts for 20-40% of thyroid cancer-related deaths. Cancer stem cell drug resistance represents a primary factor hindering treatment. This study aimed to develop targeted agents against thyroid malignancy, focusing on individual and synergistic effects of HNHA (histone deacetylase), lenvatinib (FGFR), and sorafenib (tyrosine kinase) inhibitors. Patients with biochemically and histologically proven papillary thyroid cancer (PTC) and ATC were included...

INTRODUCTION: Hyperthyroidism is rarely associated with malignancy, but it cannot rule out thyroid cancer. Although there is published data describing this coexistence, thyroid carcinomas inside autonomously functioning nodules are uncommon. PRESENTATION OF CASE: A 49-year-old woman presented with a cervical mass, unexplained weight loss and anxiousness, sweating and insomnia. On physical examination, she had a palpable left thyroid nodule. Thyroid function tests showed suppressed TSH (<0,1 uUI/mL), thyroxine 1,44 ng/dL (normal range 0,70-1,48) and triiodothyronine 4,33 pg/mL (normal range 1,71-3,71)...

BACKGROUND: Idiopathic pleuroparenchymal fibroelastosis (IPPFE) is a rare type of interstitial pneumonia characterized by fibroelastosis. Patients with IPPFE as well as idiopathic interstitial pneumonia often have autoimmune diseases, which sometimes coincide with hypothyroidism (HypoT). However, there have been no reports on the association between IPPFE and HypoT. The purpose of this study was to evaluate the correlation between IPPFE and HypoT. We also examined the pathological features of the thyroid glands from autopsied cases...

Follicular thyroid cancer's (FTC) excellent long-term prognosis is mainly dependent on complete surgical removal and postoperative radioactive iodine (RAI) treatment. However, once the tumour becomes RAI refractory the 10-year disease specific survival rate drops below 10 %. The aim of our study was to evaluate the prognostic and biological role of the TRAIL system in FTC and to elucidate the influence of small molecule mediated antagonization of inhibitor of apoptosis proteins (IAPs) on TRAIL-sensitivity in vitro...

Chia-Da Hsu, Yaoprapa Mathura
In January 2016, a 20-year-old female oriental small-clawed otter (Aonyx cinereus) from Night Safari in Singapore was euthanized and diagnosed with a thyroid gland carcinoma. Postmortem examination and histology also revealed metastasis to the regional lymph nodes and severe visceral pentastomiasis. Grossly, the lymph nodes were infested, and encapsulation was observed on the visceral serosal surface. Histopathologically, the lymph nodes were encysted by a thick fibrous connective capsule with minimal inflammatory response...

RATIONALE: Ectopic thyroid carcinoma within a thyroglossal duct cyst (TGDCCa) is an extremely rare entity. Thus, there is no unified appropriate therapeutic strategy, and individual approaches are controversial. PATIENTS CONCERNS: We report the case of a 21-year old woman who underwent Sistrunk procedure for a thyroglossal duct cyst (TGDC). DIAGNOSES: During histological evaluation of the resected TGDC a papillary thyroid carcinoma was found...

To evaluate the diagnostic performance of elastography alone and combined with Thyroid Imaging Reporting And Data System (TIRADS) for the assessment of non-autonomous thyroid nodules. We included 244 thyroid nodules and analyzed the visual elasticity scores, strain value (SV) and TIRADS classification. Histologic examination revealed 38 malignant (16%) and 206 benign nodules. The SV was lower in malignant nodules than in benign with an optimal cutoff ≤0.225. The visual elasticity scores showed a better diagnostic performance than the SV measurement...

The distinction between follicular thyroid carcinomas (FTCs) and follicular-patterned benign lesions is almost impossible on fine-needle aspiration cytology. Furthermore, minimally invasive FTCs (MI-FTCs) with less than 4 vascular invasion foci generally have an excellent prognosis, but there are exceptions and, so far, no molecular marker appears able to identify them reliably. We aimed to distinguish benign lesions from low- and high-risk FTCs by a small-scale combination of genes. The expression analysis of 75 selected genes was performed on 18 follicular adenomas (FAs), 14 MI-FTCs and 6 widely invasive FTC (WI-FTCs)...

Biospecimen quality can vary depending on many pre- and post-collection variables. In this study, we consider a natural disaster as a post-collection variable that may have compromised the quality of frozen tissue specimens. To investigate this possible link, we compared the quality of nucleic acids, the level of antigenicity, and the preservation of histology from frozen specimens collected before and after the power outage caused by Hurricane Sandy. To analyze nucleic acid quality, we extracted both DNA and RNA and performed capillary electrophoresis to compare the quality and concentrations of the nucleic acids...

PURPOSE: Hyperhomocysteinemia is a known cardiovascular risk factor and a key player in the inflammatory activation of autoimmune diseases. Hashimoto's thyroiditis (HT) is the leading cause of hypothyroidism which, in itself, has been associated with a significant raise of homocysteine (Hcy) levels and increased cardiovascular risk. Our aim was to assess the impact of HT on Hcy levels in patients with acute hypothyroidism. METHODS: We prospectively enrolled 121 patients (mean age: 46 years, F/M = 102/19) with acute post-surgical hypothyroidism...

CASE: A 49-year-old man presented with a rapidly growing thigh mass. Histologic analyses demonstrated separate regions that were consistent with a collision tumor composed of a primary leiomyosarcoma and a metastatic medullary thyroid carcinoma. After responding to chemotherapy, the patient underwent resection of the tumor and a total thyroidectomy; he was disease-free 9 years after the diagnosis. CONCLUSION: A wide diagnostic differential and thorough histologic analysis are necessary in patients presenting with neoplasms of the extremities...

CASE: We report the case of a 38-year-old woman who presented with a lytic bone lesion in the left scapula. A biopsy showed a tumor with the histologic appearance of thyroid tissue. She also was found to have a thyroid nodule and an enlarged ovary, both of which were excised. The thyroid nodule turned out to be a benign colloid nodule, and the ovary contained a monodermal teratoma composed of thyroid tissue (struma ovarii). The lesion in the scapula eventually was proven to be metastatic malignant struma ovarii...

AIM: Solitary cystic masses of the lateral neck in an adult patient can pose a diagnostic dilemma. Malignancy must be ruled out since metastases arising from H&N cancers may mimic the presentation of benign cystic masses. Only a small number of studies have investigated the diagnostic management and malignancy rate of clinically benign solitary cervical cystic lesions. There are no established guidelines for the diagnostic evaluation. METHODS: Retrospective review of the clinical, cytological, radiological, and pathological records of all adult patients (> 18 years) operated on for second branchial cleft cysts (BrCC) between 1/2008-2010/2016...

Parathyroid carcinoma (PC) is a very rare endocrine tumour, usually characterized by symptoms such as a neck mass, dysphonia, severe hypercalcemia exceeding 140 mg/L and elevated serum parathyroid hormone levels, even more than 5 times the upper limit of normal. Non-functioning parathyroid cancer is extremely rare and, in this case, its pre-operative diagnosis is often difficult. A 54-year old female patient, referring dysphagia and dysphonia, underwent neck ultrasound and neck CT. A left thyroid nodule, probably cystic, was found...
