BRAF mutations were rarely identified in 3 out of 27 (11%) patients in our series, similarly to other studies with patients suffering from mucosal melanomas who reported 1 out of 17 (Cohen et al, 2004) and 0 out of 13 (Edwards et al, 2004), respectively, whereas the majority of cutaneous melanomas on skin without chronic sun-induced damage harbour BRAF V600E mutations (Curtin et al, 2005). Here, BRAF is linked to cutaneous melanoma.
