Mucosal Melanoma: New Insights and Therapeutic Options for a Unique and Aggressive Disease.

Abstract

Mucosal melanoma is a rare disease that is distinct from melanomas arising at other sites in the body. While melanocytes are most abundant in the skin, they can be found in smaller numbers in the mucous membranes, as well as in the eye. There are epidemiologic, genetic, and other physiologic differences between melanomas arising from melanocytes at these various sites, and these differences have important implications for both disease prognosis and treatment. Here, we review the features of mucosal melanoma that distinguish it from melanomas arising at other sites, and we highlight recent biological discoveries and emerging treatment options for this aggressive disease.
