worldwide, thyroid cancers are the most common type of endocrine-related cancers. papillary carcinoma accounts for the most frequent type of thyroid malignancy. a rare variant of papillary carcinoma of the thyroid is the cribriform-morular variant. we report a case of solitary, cribriform-morularvariant of papillary carcinoma in a 55-year-old lady. it is important to identify this variant becau...
It is proposed that most papillary thyroid cancers originate in infancy and childhood, based on the early rise in sporadic thyroid carcinoma incidence, the pattern of radiation-induced risk (highest in those exposed as infants), and the high prevalence of sporadic papillary thyroid cancers in children and adolescents (ultrasound screening after the Fukushima accident). The early origin can be l...

The most usual form of the endocrine carcinoma is thyroid cancer (TC). In addition to papillary thyroid carcinoma (PTC), recent studies revealed incidence of RET/PTC rearrangement in other tumors, like Hürthle cell carcinoma (HCC) and even in non-carcinomatous disorders like Hashimoto's thyroiditis. Here, we present a case with concurrence of papillary thyroid carcinoma and Hürthle cell carcino...
INTRODUCTION Akt activation is involved in the pathogenesis of inherited thyroid cancer in Cowden's syndrome and in sporadic thyroid cancers. In cell culture, Akt regulates thyroid cell growth and survival; but recent data suggest that Akt also regulates cell motility in non-thyroid cell lines. We therefore sought to evaluate the role of Akt in thyroid cancer progression. METHODS We evaluated...
The aim of this study was to evaluate the relationship between abnormal expression of E-cadherin (E-CAD) and the extracapsular extension of tumors, lymph node involvement and the presence of metastasis in various types of thyroid cancers. Histopathological specimens of 35 benign thyroid lesions and 122 malignant tumors (papillary, follicular, poorly differentiated and undifferentiated cancers) ...
Nodules in the thyroid have always commanded a great deal of attention because of the fear of their being cancerous. The estimated incidence of thyroid nodules in children and young adults is about 0.22 to 1.8 percent. According to different epidemiological data, about 10 to 35 percent of thyroid cancers occur in the first two decades. The present study based on microscopic review of tissue sli...
The endothelin axis is a group of signaling molecules and their receptors that have been implicated in vascularization of cancers, with their expression being observed to change in different cancer types. In this research, we examined the expression of endothelin 1 and endothelin receptor A at the protein and messenger RNA (mRNA) levels in 123 papillary thyroid carcinomas and 40 matched lymph n...
Objective(s): As the most prevalent endocrine system malignancy, papillary thyroid carcinoma had a very fast rising incidence in recent years for unknown reasons besides the fact that the current methods in thyroid cancer diagnosis still hold some limitations. Therefore, the aim of this study was to improve the potential molecular markers for diagnosis of benign and malignant thyroid nodules to...
