Due to the detection of the V600E BRAF mutation in this fistula melanoma, it was decided not to look for alterations in genes such as CCND1 or KIT, more frequently mutated in acral and mucosal melanomas [29], since concomitant mutations in BRAF and in genes such as KIT or CCND1 are extremely rare [29]. This evidence concerns the gene KIT and mucositis.
