Thyroid carcinoma (TC) is the most frequent malignant neoplasm of the endocrine system. Molecular methods for diagnosis of invasive thyroid disease can be effectively adopted. Epigenetic factors play an important role in the diversity patterns of gene expression and the phenotypic and biological characteristics of TC subtypes. We aimed to review epigenetic changes in the main subtypes of TC, along with a presentation of the methods that have examined these changes, and active clinical trials for the treatment of advanced TCs targeting epigenetic changes. A literature analysis was performed in MEDLINE using PubMed, Elsevier, and Google Scholar for studies published up to 2016, using the keywords: "Epigenetic alterations" OR "Epigenetic changes", "thyroid cancers", "papillary thyroid cancer", "medullary thyroid cancer", "follicular thyroid cancer", and "anaplastic thyroid cancer", which resulted in 310 articles in English. All related abstracts were reviewed and studies were included that were published in English, had available full text, and determined the details of the methods and materials associated with the epigenetic patterns of TC and its subtypes (100 articles). Analysis of epigenetic alterations in TC subtypes helps to identify pathogenesis and can play an important role in the classification and diagnosis of tumors. Epigenetic mechanisms, especially aberrant methylation of DNA and microRNAs (miRs), are likely to play an important role in thyroid tumorigenesis. Further studies are required to elucidate the role of histone modification mechanisms in TC development.

Primary squamous cell carcinoma of the thyroid (PSCCT) is a rare malignancy with a poor prognosis. Therefore, early diagnosis and treatment are critical to the survival of patients and to improve their quality of life. However, diagnosing this illness is challenging.

Anaplastic thyroid carcinoma (ATC) is a rare, yet extremely aggressive form of thyroid cancer characterized by rapid growth and early metastasis to distant sites. Cardiac involvement is very uncommon and the presentation of cardiac metastasis in ATC can vary widely, highlighting the importance of early clinical recognition. We describe an extremely rare case of metastatic ATC that spread to the right ventricle.

Introduction Thyroid malignancy remains a significant global health concern, making the accurate differentiation between benign and malignant thyroid nodules crucial for optimal patient management. Fine-needle aspiration cytology (FNAC) is the gold-standard preoperative diagnostic tool, and The Bethesda System for Reporting Thyroid Cytopathology provides a standardized framework for interpretation. This 10-year retrospective study evaluated the malignancy risk in surgically treated patients with thyroid nodules classified as Bethesda Category III by comparing FNAC findings with histopathological outcomes.

Papillary thyroid cancer (PTC) is the most frequent thyroid malignancy. Recently, the incidence has become widespread among both male and female individuals worldwide. In this article, we aim to report a 32-year-old Saudi female who presented with a painless lateral neck mass for more than seven months, and on excisional biopsy, was found to have features of PTC.

Background: With rising well-differentiated thyroid cancer (WDTC) incidence, the appropriate treatment choice remains controversial for T1 tumors <2 cm. This study analyzed differences in surgery refusal and survival outcomes between T1a (<1 cm) and T1b (1-2 cm) WDTC, examining the demographic and clinical characteristics associated with patients who decide to either undergo or refuse recommended surgery.
Methods: We studied 81,664 T1N0M0 WDTC patients in the Surveillance, Epidemiology, and End Results (SEER) registry [2000-2019].
