Preoperative cytologic interpretation of noninvasive follicular thyroid neoplasm with papillary-like nuclear features: a 1-year multi-institutional experience

NIFTP are tumors demonstrating nuclear features similar to those seen in PTC. Our series shows that a preoperative diagnosis of “suspicious for malignancy” or “malignant” is uncommon in NIFTP, suggesting that there are sufficient cytomorphologic differences between PTC and NIFTP to allow for the suspicion of NIFTP on FNA specimens.
