KIT and cutaneous melanoma: The genetic abnormalities commonly associated with these two subtypes of cutaneous melanoma are neurofibromin 1 (NF1), NRAS, BRAF non-V600E mutations, or KIT in CSID, while non-CSID is associated with BRAF V600E mutations, suggesting that the non-CSID might originate from nevi (Figure 1) [2,71,72].
