Figure 1 Graphical representation of the number of lesions containing mutations for each of the genes for which at least one mutation was identified. A: All lesions. B: BRAF inhibitor (BRAFi)–associated lesions. BAVK, BRAF inhibitor–associated verrucous keratosis; KA, keratoacanthoma; SCC, squamous cell carcinoma.

Figure 2 Representative examples of both the hematoxylin and eosin (H&E) appearances and immunohistochemical (IHC) staining for the phosphorylated form of extracellular signal–related kinase (pERK) in a BRAF inhibitor–associated verrucous keratosis (A and B, respectively), a keratoacanthoma (C and D, respectively), and a squamous cell carcinoma (E and F, respectively). All three lesions originated from patients undergoing treatment with a BRAF inhibitor. A, C, and E: H&E staining. B, D, and F: IHC staining for pERK.
