The association between dermoscopic features and BRAF mutational status in cutaneous melanoma: Significance of the blue-white veil.

Background: The genetic basis of melanoma affects its clinicopathologic characteristics and increasingly influences its management. B-Raf proto-oncogene, serine/threonine kinase gene (BRAF)-mutated melanoma may present with specific dermoscopic features. Objectives: To identify the dermoscopic features associated with BRAF mutation in cutaneous melanoma and to evaluate a model capable of predicting BRAF mutations on the basis of dermoscopic and clinicopathologic features that are easily accessible in normal clinical practice. Methods: A prospective, cross-sectional, observational, and descriptive study was performed. A total of 93 cutaneous melanomas with dermoscopic images from 93 patients…
