Noninvasive follicular thyroid neoplasm with papillary-like nuclear features in the pediatric age group

BACKGROUND: The most common malignant thyroid neoplasm in children is papillary thyroid carcinoma (PTC). In 2015, the Endocrine Pathology Society introduced the terminology \u201cnoninvasive follicular thyroid neoplasm with papillary-like nuclear features\u201d (NIFTP) to replace the noninvasive follicular variant of PTC. The objective of the current study was to evaluate previously diagnosed PTC in the pediatric population, reappraise it for NIFTP, and discuss the impact of NIFTP on the risk of malignancy (ROM) for each The Bethesda System for Reporting Thyroid Cytopathology category in the pediatric population. METHODS: The electronic databases of both study institutions were searched for all thyroidectomy specimens in patients aged
