Although relatively uncommon, malignant melanoma in African-Americans and other minority ethnic populations represents an aggressive disease highly associated with invasive lesions and a more advanced stage of disease at diagnosis, and consequently with a decreased survival compared with Caucasians. Data on biology of melanoma in African-Americans is very limited, which complicates the analysis of epidemiological information, as well as identification of accurate prognostic variables. This review article explores critical features of melanoma in African-Americans that distinguish it from disease seen in Caucasians, including the clinical presentation, histological patterns, prognostic indicators, and etiology. Emerging data from biologic and genetic studies will also be discussed, raising the possibility that melanoma in pigmented skin may represent molecular distinct cancers that are inherently more aggressive. Improved understanding of the unique manifestations of melanoma in African-Americans, and its underlying tumor biology, will help improve clinical detection, optimize preventative measures through public health education, and potentially lead to the development of novel targeted therapeutic approaches.

There is a paucity of information on racial and ethnic disparities relating to barriers to care in healthcare access and utilization in patients with cutaneous malignancies. We conducted a cross-sectional analysis of adults with melanoma, basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) in the National Institutes of Health (NIH) All of Us Research Program collected between May 2018 and July 2022. Participants included adults (aged 18 or older) with cutaneous malignancy who completed the Health Care Access and Utilization survey.

Article Synopsis
- Racial and ethnic minorities, particularly Black and Hispanic patients, show worse outcomes in skin cancer treatment compared to non-Hispanic White patients, with Black patients having the highest rates of treatment refusal.* -
- An analysis of over 151,000 patients revealed that Black and Hispanic individuals faced longer delays from diagnosis to treatment and greater tumor depth, contributing to a higher 90-day mortality rate.* -
- The findings highlight a pressing need for further research on quality of life and targeted interventions to address these disparities in skin cancer outcomes.*
Background: Poor melanoma outcomes in people of color (POC) are attributed to a variety of factors, including healthcare literacy, socioeconomic status, and healthcare access barriers. Methods: We designed a survey to determine if visual and audio media (VAM) would increase POC's understanding of the need for sunscreen and their willingness to use it. Patients recruited at a dermatology clinic were asked to watch a 2.

Hidradenitis suppurativa (HS) is a chronic inflammatory skin condition whose pathogenesis is not well established. An association between HS and obesity is suggested but few studies explore specific dietary drivers. Non-Hispanic Blacks have the highest HS prevalence and obesity rates as well as the highest UPFs consumption rates, as opposed to Hispanics who have the lowest prevalence of HS despite having the second highest obesity rates in the US.
