The recent introduction of non-invasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTP) in the WHO classification of thyroid tumors has significantly modified the risk of malignancy of cytological diagnoses. In fact, while this tumor was previously classified as a carcinoma (the encapsulated, non-invasive form follicular variant of papillary thyroid carcinoma), it is now considered a neoplasm with low malignant potential. Given that the NIFTP cytological features are not specific and overlap with other pathologic entities, there is no specific cytological diagnostic category for NIFTP. To obtain more robust information about the cytological findings associated with NIFTP, we systematically reviewed published articles and carried out a meta-analysis of the data.
