Because the Mitogen-Activated Protein Kinase (MAPK) pathway plays such a significant role in melanoma development, we explore v-raf murine sarcoma viral oncogene homolog B (<i>BRAF)</i> and neuroblastoma RAS viral oncogene homolog (<i>NRAS)</i> mutations in mucosal melanoma and compare them to the mutation profiles in cutaneous melanoma and other tumors with <i>BRAF</i> and <i>NRAS</i> mutations.
