Kim TH, et al. - A detailed scrutiny was carried out of the molecular genotype-phenotype correlations of encapsulated follicular variant of papillary thyroid carcinoma (FVPTC). No variations were observed in the clinicopathologic or molecular profiles between noninvasive and invasive encapsulated FVPTCs, with the exception of vascular and capsular invasion. Hence, the diagnosis of NIFTP, like follicular adenoma, possibly necessitated surgical resection and exclusion of those tumors with any papillae.
