Medullary thyroid carcinoma (MTC) is an aggressive and rare cancer with limited treatment options for metastatic disease. Due to this, there is a need for a better understanding of MTC biology in the hope of improved treatments. One area of improved understanding of cancer biology is epigenetics. Epigenetics is defined as cellular processes which alter gene expression independent of changes in the primary DNA sequence. These processes include modifications such as DNA methylation, microRNA deregulation and post-translational histone modifications, all of which have been implicated in tumorigenesis of MTC...

REVIEW
Alfred King-Yin Lam, Nassim Saremi
The aim of this systematic review is to study the features of cribriform-morular variant of papillary thyroid carcinoma (CMV-PTC) by analysing the 129 documented cases in the English literature. The disease occurred almost exclusively in women. The median age of presentation for CMV-PTC was 24 years. Slightly over half of the patients with CMV-PTC had familial adenomatous polyposis (FAP). CMV-PTC presented before the colonic manifestations in approximately half of the patients with FAP. Patients with FAP often have multifocal tumours in the thyroid...

Surgical emphysema secondary to tracheal tear is a rare but serious complication after thyroidectomy. It is usually resolved by conservative management; but in case of compromised airway, early airway control and surgical intervention is required. This is the case report of a 52-year woman diagnosed as thyroid carcinoma, who developed rapidly progressive surgical emphysema involving head and upper thorax, following total thyroidectomy, in post anesthesia care unit (PACU). The complication was related to tracheal tear occurring during excision of huge thyroid mass, encroaching trachea...

Papillary thyroid carcinoma is the most frequent histologic type of thyroid tumor. Few studies investigated the role of c-KIT expression in thyroid tumors, suggesting a role for this receptor and its ligand in differentiation and growth control of thyroid epithelium and a receptor loss following malignant transformation. We investigated and correlated c-KIT expression levels and two known markers of thyrocytes differentiation, PAX8 and TTF-1, in malignant and benign cytological thyroid samples. Moreover, we performed functional studies on human papillary thyroid carcinoma cell line to associated c-KIT expression to thyrocytes differentiation and tumor proliferation...

A variety of tumors may involve the eyelid, most of which are primary, but rarely can be metastatic. Previously reported eyelid primary carcinomas with neuroendocrine features include Merkel cell carcinoma, apocrine and eccrine gland carcinoma, sebaceous gland carcinoma, and one report of primary "well-differentiated neuroendocrine tumor." Herein we report the first case of primary cribriform carcinoma of the eyelid with neuroendocrine features. The patient is a 75-year-old black man who presented to the clinic with a 5-year history of a slowly growing, non-painful, non-exudative lesion of his left lower eyelid...

Carney complex syndrome is an autosomal dominant familial tumor syndrome first described by Carney et al. in 1985. The diagnostic criteria include endocrine hyperactivity and spotty skin pigmentation. A 73-year-old woman with cerebral infarction was referred to our department because her brain magnetic resonance imaging(MRI)revealed a pituitary tumor. Her blood tests revealed elevated levels of growth hormone(GH), thyroid stimulating hormone(TSH), and insulin-like growth factor-1(IGF-1). We suspected the presence of a GH-secreting tumor and performed the operation...

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: BRAF V600E mutation in PTC is particularly prevalent in Korea and a considerable number of BRAF-wild PTCs harbor RAS mutations. In addition, subsets of other genetic alterations clearly exist, but their prevalence in the Korean population has not been well studied. Recent increased insight into noninvasive encapsulated follicular variant PTC (NIE-FVPTC) has prompted endocrine pathologists to reclassify this entity as "noninvasive follicular thyroid neoplasm with papillary-like nuclear features...

Clear cell carcinoma of the thyroid has been regarded as a variant of follicular (FTC) or papillary (PTC) thyroid carcinoma. 21 primary thyroid carcinomas with clear cell features, diagnosed in 20 patients (12 female, 8 male) were identified between 1992 and 2012 (0.5% of in-house thyroid carcinomas). H&E slides were reviewed. SNaPshot multi-gene mutational analysis and a translocation panel were successfully performed on 15 of these cases. 12 (57%) were FTC, 5 were conventional PTC, 2 were follicular variant (FV) of PTC, and 2 were poorly differentiated thyroid carcinoma (PDTC)...

Thyroglossal duct cyst (TGDC) carcinomas are rarely encountered in the pediatric population. The clinical behavior of these tumors in the pediatric setting is unclear and management is not well defined. Two cases of pediatric thyroglossal duct cyst carcinoma were identified in a review of all thyroglossal duct cysts diagnosed over a ten year period. These two cases were analyzed along with 57 cases of thyroglossal duct cyst carcinoma affecting patients less than 21 years of age compiled from the English literature...
