In that location mean values of dendritic cell number in dysplastic nevi versus invasive melanomas were, respectively, 14.72 versus 16.82 for CD1a, 32.00 versus 35.20 for CD1c, 1.0 versus 0.82 for DC-LAMP+, and 3.22 versus 4.00 for DC-SIGN+. This evidence concerns the gene CD1A and dysplastic nevus.
