Uncommon <i>BRAF</i> mutations in the follicular variant of thyroid papillary carcinoma: New insights

Abstract

Uncommon BRAF mutations were observed only in FVPCs and were linked to less aggressive behavior. Negative/weak VE1 expression was observed in both wild-type and uncommon BRAF mutations. The current investigation did not reveal any plump cells or morphologic BRAF findings in samples that had uncommon BRAF mutations. In the authors' experience, BRAF mutations detected by DNA methods were more accurate in identifying FVPCs.
