Our understanding of neoplasia is evolving at a rapid pace in these exciting times, where recent molecular pathology advances are reinforcing and fine tuning morphological divisions and classification. Thyroid gland neoplasia in general, and Hürthle-cell neoplasms in particular, are no exception in the current era of histopathology-molecular biology paradigm. In this review paper, we discuss the rationale that led pathologists in the past to separate Hürthle-cell neoplasms into its own dedicated diagnostic category, and provide an algorithmic approach to the differential diagnosis of oncocytic lesions of the thyroid.

Chronic immunosuppression is known to cause an increased risk of cancers in organ transplant recipients leading to the rise in morbidity and mortality among these patients. Recent studies have observed that thyroid lesions are more frequently encountered in kidney transplant recipients. A 45-year-old woman with history of chronic hypertension, kidney transplant and graft failure, was admitted for assessment for a second renal transplant and detected to have a thyroid nodule by ultrasound (US).

Mutations in the miRNA enzyme gene DICER1 have been reported in several endocrine malignancies and is associated to the rare tumour-predisposing DICER1 syndrome. DICER1 mutations have been reported in subsets of follicular thyroid carcinoma (FTC), but the role of DICER1 in follicular thyroid tumorigenesis has not been extensively studied. In this study, we investigate the role of DICER1 in 168 follicular thyroid tumours and in an FTC cell line. Read More

Anaplastic thyroid carcinoma (ATC) exhibits an exceedingly poor prognosis, and the current treatment options are, for most cases, palliative by nature. Few reports of long-time survivors exist, although in these patients, tumors often were limited to the thyroid and/or regional lymph nodes. We describe a 64-year-old male who developed a rapidly growing mass in the left thyroid lobe. Read More

There are no reliable biomarkers to accurately differentiate indolent thyroid tumors from more aggressive thyroid cancers. This study aimed to develop new DNA methylation markers for diagnosis and recurrence risk stratification of papillary thyroid carcinoma (PTC). Thyroid tumor-specific DNA methylation profiling was investigated in 34 fresh frozen tissues, which included nontumor ( = 7), noninvasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTP,  = 6) and PTC ( = 21), using the Illumina HumanMethylation EPIC array.

The differential diagnosis of well-differentiated tumors of follicular cell origin remains the most problematic task in thyroid pathology. Specific morphologic criteria (capsular and/or vascular invasion, nuclear characteristics) are crucial in the diagnosis of these neoplasms. However, the assessment of malignant features is inconclusive in some cases. Read More

Background: Analysis of molecular markers in addition to cytological analysis of fine-needle aspiration (FNA) samples is a promising way to improve the preoperative diagnosis of thyroid nodules. Nonetheless, in clinical practice, applications of existing diagnostic solutions based on the detection of somatic mutations or analysis of gene expression are limited by their high cost and difficulties with clinical interpretation. The aim of our work was to develop an algorithm for the differential diagnosis of thyroid nodules on the basis of a small set of molecular markers analyzed by real-time PCR. Read More

Background: Thyroid gland nodules are common and fine-needle aspiration (FNA) is the gold standard for screening those nodules. The Bethesda system for reporting thyroid cytolopathology standardized reporting thyroid nodules aspirations, but atypia of undetermined significance or follicular lesion of undetermined significance (Bethesda category III) was the most controversial category. The aim of our study is to review our institutional experience and analyze the clinical implications of making a diagnosis of AUS/FLUS (Bethesda category III). Read More

Although treatment options for patients with advanced and metastatic thyroid carcinoma were historically limited, developments in the past 15 years in understanding the pathogenesis of these malignancies have permitted identification of novel targeted therapies to improve outcomes. Five individual drugs and one combination therapy have achieved regulatory approval since 2011, all showing improvements in progression-free survival or high response rates. More selective targeting of mutated oncogenic kinases is leading to increasing efficacy with fewer toxicities, at least in early human trials. Read More

: To evaluate the efficacy and treatment rationale of Hürthle cell carcinoma (HCC) following a patient with progressive and metastatic HCC. HCC was recently shown to harbor a distinct genetic make-up and the mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kiase (PI3K)/AKT signaling pathways are potential targets for anti-cancer agents in the management of recurrent HCC. The presence or absence of gene variants can give a rationale for targeted therapies that could be made available in the context of drug repurposing trials. Read More

The Keap1/Nrf2 pathway is a key mediator of general redox and tissue-specific homeostasis. It also exerts a dual role in cancer, by preventing cell transformation of normal cells but promoting aggressiveness, and drug resistance of malignant ones. Although Nrf2 is well-studied in other tissues, its roles in the thyroid gland are only recently emerging. Read More

Purpose: Oncocytic (Hürthle cell) papillary thyroid carcinoma (OPTC) is a rare variant of the papillary thyroid carcinoma (PTC) which comprises approximately 1 to 11 % of PTC cases. Its clinical course and prognosis have not been comprehensively documented and the clinical outcome remains a controversial issue.

Genetic alterations activating the mitogen-activated protein kinase (MAPK) signaling pathway, most commonly and mutations, are common in papillary thyroid carcinoma (PTC). Somatic mutations of the gene, also known as mitogen-activated protein kinase kinase 1 (), coding for a signaling protein downstream of BRAF, have been found in several cancer types. The goal of this study was to investigate if functional mutations occur in thyroid cancer (TC). Read More

The extent of invasion has been shown to be prognostic in follicular thyroid carcinoma and Hürthle cell carcinoma. Our aim was to evaluate how extent of invasion impacts clinical outcome for PDTC.

Salivary glands located in the head and neck area are known to have different lesions with prominent oncocytic features. Fine needle aspiration is usually the initial approach in the management of these lesions, whether they represent neoplastic or non-neoplastic processes. Owing to the limited material present upon cytopathologic examination, knowledge of variants and subtypes of various oncocytic lesions that can occur in this area is of major importance to provide the most accurate interpretation to the patients and clinicians.

Lenvatinib is a tyrosine kinase inhibitor (TKI) with antiproliferative and antiangiogenic effects indicated for the treatment of progressive, locally advanced or metastatic progressive thyroid carcinoma, refractory to radioactive iodine therapy. Antiangiogenic therapies induce ischemic necrosis of tumor tissue, with increased risk of hemorrhagic complications.

The hyalinizing trabecular adenoma/tumor is a rare and poorly characterized follicular-derived thyroid neoplasm recently shown to harbor recurrent PAX8-GLIS1 or PAX8-GLIS3 gene fusions. Here we sought to define the repertoire of genetic alterations of hyalinizing trabecular tumors, and whether PAX8-GLIS3 fusions are pathognomonic for hyalinizing trabecular tumors. A discovery series of eight hyalinizing trabecular tumors was subjected to RNA-sequencing (n = 8), whole-exome sequencing (n = 3) or targeted massively parallel sequencing (n = 5). Read More

Hürthle cell tumors (HCT), including Hürthle cell adenomas (HCA) and Hürthle cell carcinomas (HCCs), arise in the thyroid gland and are defined in part by an accumulation of mitochondria. These neoplasms were long considered a subtype of follicular neoplasm, although HCT is now generally considered a distinct entity. HCTs exhibit overlapping but distinct clinical features compared to follicular tumors, and several studies have demonstrated that HCTs harbor distinct genomic alterations compared to other forms of thyroid cancer.
