Abstract/OtherAbstract:
Hürthle cell carcinomas behave as the most aggressive variant of differentiated thyroid carcinoma of follicular origin, with frequent recurrences and higher morbidity. Its differential diagnosis with Hürthle cell adenoma remains a problem for the clinician and for the pathologist. The vertebrate lectins, galectin-1 and galectin-3 have been implicated in the regulation of cellular growth, differentiation, and malignant transformation in thyroid neoplasms. Galectin-3, a beta-galactoside binding protein, has been recently found to be highly expressed in papillary and follicular carcinomas. The current study was undertaken to investigate immunohistochemical reactivity for galectin-3 of thyroid specimen tissues with Hürthle cell adenomas (n = 14) and carcinomas (n = 17), follicular (n = 14) and papillary (n = 11) carcinomas, colloid goiter (n = 30), Hashimoto's thyroiditis (n = 11), follicular adenoma (n = 9), and normal thyroid tissues (n = 18). Follicular (78.5%) and papillary (82.0%) carcinomas were frequently reactive for galectin-3, more often when some H rthle cells were present. There was no galectin-3 immunostaining in any of the specimens from Hashimoto's thyroiditis, colloid goiters or normal thyroid samples, whereas only one case of follicular adenoma was found positive (11.1%). By contrast, galectin-3 immunostaining in Hürthle cell carcinomas was significantly higher (59%) than in H rthle cell adenomas (7.1), p < 0.05). These results suggest that galectin-3 may potentially serve as a marker in difficult differential diagnosis cases involving Hürthle cell adenomas and Hürthle cell carcinomas.
