Lentigo maligna and lentigo maligna melanoma: contemporary issues in diagnosis and management

Karen L Connolly et al. Melanoma Manag. 2015 May.

Abstract

Lentigo maligna and lentigo maligna melanomas present diagnostic and treatment dilemmas due to their frequent presence within a background of sun-damaged skin, and their location on cosmetically and functionally sensitive areas. As the incidence of this entity is increasing, diagnostic and management controversies have developed. While surgery remains the gold standard of treatment, nonsurgical treatment options are also emerging for both adjunctive and primary therapy.

Keywords: facial melanoma; lentigo maligna; lentigo maligna melanoma; melanoma; melanoma in situ.
