Papillary thyroid carcinoma (PTC) is one of the most commonly diagnosed types of differentiated carcinoma of the thyroid. It is stated that lung is the most common site of metastasis followed by bone. The incidence of paranasal sinus (PNS) metastasis is fairly uncommon in case of thyroid carcinoma. To the best of our knowledge, no case of metastatic PTC to nasal cavity has been reported. In thi...

Background: Persistent thyroglossal duct leads to a fibrous cyst formation named thyroglossal cyst which is the most common form of congenital cyst and usually located in the midline neck below the hyoid bone. Rarely the thyroglossal cyst is associated with thyroid cancer. Although the Sistrunk procedure is often considered adequate, currently there is no clear consensus on the optimal manageme...

hbme-l is an antimesothelial monoclonal antibody that recognizes an unknown antigen on microvilli of mesothelial cells. the antibody is only relatively specific for mesothelium and is used in the differential diagnosis of mesothelioma and adenocarcinoma within the context of an appropriate immuno-histochemical panel. hbme-l has also been reported to strongly and uniformly stain papillary and fo...

clinically apparent cervical lymphadenopathy has been found at the initial presentation in 23 to 56 % of cases of papillary thyroid carcinoma. here we report tuberculous lymphadenitis mimicking metastatic lymph nodes from papillary thyroid carcinoma and suggest that tuberculosis apart from metastasis in papillary thyroid carcinoma should also be considered in the etiology of enlarged lymph node...

introduction: considering the influence of geographical, genetic and ethnic factors on the prevalence of thyroid pathological lesions, this study was performed to assess the prevalence of pathological lesions in thyroid autopsic samples obtained from adult cadavers of isfahan forensic medical center. material and methods: in this study, 202 thyroid glands from cadavers with no evidence of thyro...

thyroglossal duct cysts are the most common form of congenital cysts on the neck. the incidence of thyroid papillary carcinoma in thyroglossal duct cyst is less than 1%. in most cases the diagnosis is made postoperatively. we present a 22-year-old female with thyroid papillary carcinoma arising from thyroglossal duct cyst,identified in pathologic study after sistrunk operation.in our case there...

background: carcinomas of the thyroid follicular epithelium are the most common cancers of the endocrine system. in the diagnosis of thyroid nodules and tumors, the gold standard is histological evaluation. in cases which have morphological overlap,immunohistochemistry is needed for differential diagnosis. the purpose of this study is to investigate the expressions of cd56,hbme?1, cytokeratin 1...
