Malignant melanoma with BRAF V600K mutation

Malignant melanoma with BRAF V600K mutation is an aggressive neuroendocrine-derived cutaneous malignancy arising from pigment-producing melanocytes that harbor a specific dinucleotide substitution at codon 600, replacing valine with lysine Clinically, it frequently presents on head, neck, and trunk surfaces and carries an increased risk of regional lymph node involvement and rapid distant hematogenous dissemination

Predominantly affecting the integumentary system, this molecular subtype is more frequently observed in older adult populations with significant cumulative chronic sun damage and higher tumor mutational burdens compared to V600E-mutated melanoma Clinically, it frequently presents on head, neck, and trunk surfaces and carries an increased risk of regional lymph node involvement and rapid distant hematogenous dissemination
