Exploration of BRAFV600E as a diagnostic adjuvant in the non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP)

The non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) and encapsulated follicular variant of papillary thyroid carcinoma (EFVPTC) are distinguished from classical papillary thyroid carcinoma with predominantly follicular architecture (CPTCPFA) by distinct histomorphologic and molecular features. CPTCPFA frequently harbor the oncogenic variant BRAFV600E while NIFTP and EFVPTC are largely RAS-driven. CPTCPFA have rare papillae and intranuclear pseudoinclusions that may distinguish them from NIFTP or EFVPTC.
