P53 and Expression of Immunological Markers May Identify Early Stage Thyroid Tumors

Figure 1

Immunohistochemical expression of p53 in thyroid lesions. Scarce cells are positive in one case of adenoma (×500); (b) negative goiter nuclei (×400); (c.1) papillary carcinoma showing high expression of p53 (×400); (c.2) papillary carcinoma showing negative expression; (d) follicular variant of papillary thyroid cancer showing moderate expression of the protein (×640); and (e) follicular carcinoma showing high expression of p53 (×400).
