Importance: Strategies to non-invasively detect cutaneous melanoma generally focus on differentiating melanoma from non-melanoma lesions. However, given the variabilities in practice and lack of guidelines, it is important for clinicians to understand how such strategies and technologies perform on borderline lesions of uncertain clinical behavior.

Tools that help reduce the number of surgical biopsies performed on benign lesions have the potential to improve patient care. The pigmented lesion assay (PLA) is a noninvasive tool validated against histopathology that helps rule out melanoma and the need for surgical biopsies of atypical pigmented skin lesions. Genetic information is collected using adhesive patches and the expression of two genes, LINC and PRAME, is measured. By using genetic material collected noninvasively and to further validate the PLA, somatic hotspot mutations in genes known to be drivers of early melanoma development (BRAF other than V600E, NRAS, and the TERT promoter) can also be identified…
