Core Tip

Core tip: In this article, we focus on BRAF inhibitors, and their relationship to colonic polyps. As is already known, colonic polyps may arise from BRAF inhibitor treatment of melanoma, possibly due to paradoxical activation of the mitogen-activated protein-kinase pathway. In this article, we postulate a novel hypothesis, that the established phenotypic and molecular characteristics of serrated colonic polyps offer an intriguing insight into the pathobiology of BRAF inhibitor induced colonic polyps.
