영문 초록

With the wide use of ultrasonography and fine needle aspiration of the thyroid gland, the incidence of papillary microcarcinoma of the thyroid gland is rapidly increasing nowadays. To improve the diagnostic accu-racy of histopathologic findings of papillary thyroid carcinoma, various molecular markers have been used recently. We analysed the expression of galectin-3, cytokeratin 19 and HBME-1, using immunohistochemical tech-nique in 37 cases of papillary microcarcinoma of the thyroid gland to evaluate the diagnostic value of these molecular markers. Immunohistochemically, galectin-3 expression was found in 37 cases of papillary microcarcinoma. Its loca-lization was mostly cytoplasmic. Cytokeratin 19 expression was found in 36 cases. It was mostly localized to the cytoplasm and membrane. HBME-1 expression was found in all cases. Its localization was plasma mem-brane. The expression of these three molecular markers was negative in the adjacent normal thyroid tissue and accompanying benign lesions, although there are scattered foci of incomplete positive staining in cases of Ha-shimoto’s thyroiditis. Our findings suggest that the immunohistochemical staining using antibodies for galectin-3, cytokeratin 19 and HBME-1 is an useful adjunctive method for the histopathological diagnosis of a papillary microcarcinoma of the thyroid gland.
