NCI Definition: A differentiated adenocarcinoma arising from the follicular cells of the thyroid gland. Radiation exposure is a risk factor and it is the most common malignant thyroid lesion, comprising 75% to 80% of all thyroid cancers in iodine sufficient countries. Diagnostic procedures include thyroid ultrasound and fine needle biopsy. Microscopically, the diagnosis is based on the distinct characteristics of the malignant cells, which include enlargement, oval shape, elongation, and overlapping of the nuclei. The nuclei also display clearing or have a ground glass appearance. [1]

Thyroid gland papillary carcinomas most frequently harbor alterations in BRAF, NRAS, HRAS, ATM, and KMT2D [2].

Most Commonly Altered Genes in Thyroid Gland Papillary Carcinoma

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