Figure 1
Clinical images of nevus spilus–type CMN in six different patients. The café-au-lait macule background is often invisible at birth. Two separate lesions are indicated in one patient. CMN, congenital melanocytic nevi. Written consent was obtained for publication of all photographs.
Figure 2
Figure 2
Sequencing results showing NRAS mutation. Next-generation sequencing reads of blood (upper left), café-au-lait macule (upper centre), and overlying CMN (upper right) from the same patient showing mutation NRAS c.183A>C p.Q61H. Note the absence of mutation in the blood, and the much lower percentage of mosaicism in the café-au-lait than the CMN, as would be expected from the number of affected cells in a biopsy sample. Sanger sequencing (below) confirmation of the heterozygous pQ61H mutation in CMN. CMN, congenital melanocytic nevi.
