Aims of this study were to further clarify patterns of cMYC expression in thyroid carcinomas across the spectrum of morphology and disease aggressivity, to evaluate potential cMYC diagnostic usefulness, to find a correlation (if any) between cMYC and BRAFV600E expression in thyroid carcinomas, and to determine the extent to which cMYC may contribute to carcinogenesis. This evidence concerns the gene MYC and thyroid gland carcinoma.
