Abstract

Identification of new potential markers that may help in the diagnosis of benign and malignant thyroid lesions is needed. By comparative 2-dimensional gel electrophoresis of microdissected cells from tumors and normal thyroid tissue, we identified a new protein, S100C, which is highly expressed in papillary carcinomas. In order to validate this finding, we investigated the immunohistochemical expression and the potential role in diagnosis of these markers in 94 specimens representing the spectrum of malignant and benign thyroid lesions. Normal thyroid tissue was evaluated in 57 specimens. Galectin-3, a marker reported as specific for malignant lesions, was also evaluated in the same lesions. S100C protein was expressed in the nuclei of normal tissue, hyperplastic nodules, and follicular adenomas and carcinomas. Papillary carcinomas showed a strong, but cytoplasmic, pattern of staining. Galectin-3 immunostaining was strongly positive in papillary carcinomas, and negative in benign lesions, confirming its value in differential diagnosis. These findings suggest that immunohistochemical staining of S100C could be helpful in the pathological study of thyroid lesions, especially in cases in which follicular variants of papillary carcinoma and follicular carcinoma are considered in the differential diagnosis.
