Racial and Ethnic Differences in the Clinical Presentation and Outcomes of Acral Lentiginous Melanoma.

Racial and Ethnic Differences in the Clinical Presentation and Outcomes of Acral Lentiginous Melanoma. Br J Dermatol. 2020 Jul 19;: Authors: Behbahani S, Malerba S, Samie FH Abstract Acral lentiginous melanoma (ALM) is one of the four major subtypes of cutaneous melanoma (CM) and occurs on the palms, soles, and nail beds of the body. CM has often been associated with sun exposure1 , but ALM occurs in generally unexposed anatomic sites. While the aetiology remains largely unknown, melanocytic nevi, trauma, pressure, ultraviolet light, and gene mutations have been postulated in ALM development.2 ALM represents about 2-3% of all melanomas but represents a much higher proportion of CM in darker-skinned individuals.3 Racial and ethnic differences have been shown in CM.4 Due to its rarity, few studies have closely examined the racial differences in ALM.3 Our study aims to investigate racial and ethnic differences in clinical presentation and outcomes in patients with ALM.
