background: there are inter-observer disagreements between papillary thyroid carcinoma (ptc) with other follicular lesions of thyroid in aspect of diagnosis. cd56 is present on follicular epithelial cells of the normal thyroid. we evaluated the diagnostic value of cd56 expression in ptc, follicular thyroid lesions, and follicular thyroid neoplasms. materials and methods: seventythree cases diag...

undesired radiation exposure to caregivers is an important problem in radioiodine therapy in thyroid carcinoma patients, especially when patient is non-ambulatory. special precautions are needed to keep the exposure to caregivers low when higher dose of radioiodine is necessary. here we present a case-report of a 74-year old male patient with papillary thyroid carcinoma with local invasion and ...

background: the aim of this study was to understand any association between differentiated thyroid carcinoma (dtc) and ile3434thr xrcc7 gene polymorphism (genbank accession number: rs7830743). dtc is the most prevalent thyroid neoplasm, which includes papillary and follicular cell carcinoma. xrcc7 gene encodes a protein that functions in non-homologous end joining dna repair pathway. non-synony...

BACKGROUND A study was begun in 1965 to 1966 to determine whether children exposed to radioactive iodine from nuclear weapons testing at the Nevada Test Site from 1951 through 1962 were at higher risk of thyroid disease. In 1993, we reported that among those examined in 1985 to 1986 (Phase II) there was an association between radiation from the Nevada Test Site and thyroid neoplasms. METHODS ...

The aim of the study was to assess the intensity and distribution of galectin-3 expression in benign and malignant thyroid neoplasms by immunohistochemical method. Immunohistochemical expression of galectin-3 was analyzed in surgical thyroid specimens from 82 patients with histopathologic diagnosis of follicular adenoma (n = 32), Hürthle cell adenoma (n = 10) and papillary carcinoma (n = 40). R...

BACKGROUND High-resolution real-time ultrasonography (US) can detect characteristics of thyroid nodules, but the US differentiation between malignant nodules and benign nodules is not well described. HYPOTHESIS Ultrasonography is useful for predicting malignancy of thyroid nodules. DESIGN A retrospective study of 329 thyroid nodules (> or =5 mm) in 309 patients comparing US characteristics ...

OBJECTIVES The aim of the study was to demonstrate and evaluate the expression of cyclin D1, a protein connected with a cell cycle, by means of the immunohistochemical method in malignant thyroid neoplasms. The purpose of the analysis of the results was to explain the relation between cyclin D1 in thyroid cells and neoplasm transformation. MATERIAL AND METHODS The study was conducted on thyro...
