Usage notes

The term malignant melanoma is synonymous with melanoma in present-day medicine because the molecular biologic understanding and convened terminology of benign and malignant cutaneous neoplasms have been refined since the term melanoma entered use. While this makes malignant melanoma technically redundant, the term remains in frequent use alongside its now-synonymous counterpart. More details are offered at Melanoma § Terminology.
