The presence of a V92M or R allele (D84E, R151C, R160W, D294H) was associated with increasing size of the CMN, implying a growth-promoting effect of these alleles.
The paradoxically higher incidence of BRAF(V600E) mutations in medium-sized compared with giant CMNs suggests that the presence of the BRAF(V600E) mutation may play different roles between medium and giant CMNs in melanocytic tumorigenesis.
