NCI Definition: An adenocarcinoma arising from the thyroid gland showing extensive evidence of follicular cell differentiation. According to the nuclear features of the malignant follicular cells, it is classified either as papillary, or follicular carcinoma. [1]

Well-differentiated thyroid gland carcinomas most frequently harbor alterations in BRAF, NRAS, RET, TP53, and HRAS [2].

Most Commonly Altered Genes in Well-Differentiated Thyroid Gland Carcinoma

BRAF Mutation, BRAF Exon 15 Mutation, BRAF Codon 600 Missense, BRAF V600E, and NRAS Mutation are the most common alterations in well-differentiated thyroid gland carcinoma [2].
