Many individuals with vitiligo are uncertain about their skin cancer risk, phototherapy risks, and recommended sun protective practices. This study examined the perceived skin cancer risk and sun protective practices among individuals living with vitiligo. A secondary objective was to understand where participants obtain this information. This was a prospective cross-sectional study. An online survey was distributed to vitiligo support group leaders globally who shared the survey with their members. Individuals over the age of 18 and with vitiligo were included. There were 209 survey respondents, the majority were between the ages 35-54 (45.5%, n = 95), female (70.8%, n = 148), White (66.0%, n = 138). Nearly half of respondents believed they were at increased risk of skin cancer because of their vitiligo (45.5%, n = 95) and nearly a quarter (22.5%, n = 47) believed that phototherapy increased their risk of skin cancer. Having vitiligo affected sun protective practices with less than a quarter (24.4%, n = 51) of respondents using sunscreen daily or often prior to their vitiligo diagnosis in comparison to the majority of respondents (60.3%, n = 126) using it after their vitiligo diagnosis. The three most common sources where patients obtained information were the internet and social media (46.4%, n = 97), vitiligo support groups (23.4%, n = 49), and dermatologists (20.6%, n = 43). Despite evidence indicating a decreased risk of skin cancer in individuals with vitiligo and supporting the safety of narrowband ultraviolet B phototherapy, many participants believed they were at an increased risk of skin cancer. Findings were sub-stratified and showed differences in sunscreen usage based on gender, skin color, and percent depigmentation. This study also found nearly half of respondents obtained information related to vitiligo from the internet and social media. The number of participants may limit the generalizability of the findings. Survey questionnaires are also subject to response bias. The findings from this study highlight demographic variations in sunscreen usage which may help guide the development of targeted interventions to improve sun protective behaviors among diverse populations with vitiligo. In addition, this study suggests certain sun protective practices and skin cancer risk perceptions may vary based on extent of depigmentation. Lastly, this study also demonstrates the internet and social media as a popular source for obtaining information, emphasizing the need for dermatologists to leverage various online communication channels to help disseminate accurate information.

Disorders of hyperpigmentation are common and challenging conditions which can arise due to a myriad of etiologic factors. Many of them can present across skin types but are more common in skin of color individuals with Fitzpatrick skin types III-VI. Facial hyperpigmentation, in particular, can have a significant impact on the quality of life of affected individuals due to its increased visibility. This article provides a comprehensive review of disorders of facial hyperpigmentation including epidemiology, pathogenesis, diagnostic considerations, and treatment approaches for these conditions.

Clinical trials are an essential component of research for determining the safety and efficacy of treatments for medical diseases. In order for the results of clinical trials to be generalizable to diverse populations, they must include participants at ratios that are reflective of national and global populations. A significant number of dermatology studies not only lack racial/ethnic diversity but also fail to report data on minority recruitment and enrollment. Reasons for this are multifold and are discussed in this review. Although steps have been implemented to improve this issue, greater efforts are needed for sustained and meaningful change.

BACKGROUND: Radiofrequency (RF) and radiofrequency microneedling (RFM) for rhytides, scarring, and skin rejuvenation are believed to have a lower risk of postprocedural dyspigmentation in darker skin types. OBJECTIVE: To explore the safety and efficacy of RF and RFM in Fitzpatrick skin Types III to VI. METHODS AND MATERIALS: A systematic review of PubMed/MEDLINE databases from 2000 to 2021 using combinations of the terms radiofrequency, microneedling, skin of color, and Fitzpatrick was performed. Exclusion criteria included non-Fitzpatrick skin Types III-VI patient population, nonprimary articles, nonskin radiofrequency, and nonhuman studies. RESULTS: Thirty-five articles addressing the use of RF or RFM in skin of color were identified-22 for skin rejuvenation, 7 for acne scars, 4 for nonacne scars, 1 for hyperpigmentation, and 1 for acne treatment. Seven studies noted transient postinflammatory hyperpigmentation, 1 observed mild prolonged hyperpigmentation, and only 1 study reported permanent scarring. CONCLUSION: Radiofrequency and RFM seem to have a low risk of scarring or hyperpigmentation in skin of color. This review demonstrates that these procedures have been successfully used primarily for rhytides, acne scarring, and skin rejuvenation. However, a large proportion of the studies lack strong quality evidence.

Although racial and ethnic demographics are shifting in this country, it is not reflected in the diversity of clinical trial research participants; science, technology, engineering, and mathematics pipeline programs; or the workforce in the field of dermatology. Barriers to recruitment of minority patients for research studies also exist for numerous reasons including lack of education of prospective subjects, lack of awareness of ongoing trials, and mistrust within the health care system. Gaps in the science, technology, engineering, and mathematics pipeline for racial and ethnic minorities, particularly Black, Hispanic/Latinx, and American Indian or Alaska Native, are due in large part to structural racism. Lack of exposure as well as lack of educational, mentorship, and research opportunities contribute to gaps in the dermatology workforce. Having a representative population in the dermatology workforce and in clinical research trial patients is essential for optimum patient care, excellence in the specialty, and knowledge of appropriate treatments for minority populations. This article will discuss knowledge gaps for increasing minority subjects who participate in clinical research trials and discuss mechanisms to engage this community in trial recruitment. Additionally, this article addresses lack of racial and ethnic diversity of the dermatology workforce and performance gaps in the recruitment of racial/ethnic minorities into dermatology.
RESUMO
Various studies have revealed a disproportionately low representation of skin of color (SOC) dermatology in the medical education system of the United States. This disparity contributes to adverse experiences, missed and/or delayed diagnoses, and overall health inequities for individuals of color. The lack of sufficient SOC education begins at the medical school level and continues throughout residency, fellowship, and beyond formal training. This lack of education can be seen in the dearth of images of common and uncommon skin conditions in darker skin in widely used textbooks and educational resources as well as in the lack of formal training in SOC in many residency programs. Thus far, there have been valuable strides to make dermatologic education more inclusive of all skin colors, but there remains significant work to be done. With the population of the United States expected to continue to diversify and with the expectation that SOC will be a trait of over half of the population of the United States by 2050, it is important to strive for health equity by ensuring that comprehensive and inclusive medical training incorporates SOC. This paper will explore the issue of gaps in medical education in SOC dermatology at all levels and offer a strategic call to action to aid in rectifying this situation.
RESUMO
Skin of color (SOC) populations include those who identify as Black/African, Hispanic/Latinx, Asian/Pacific Islander, American Indian/Native Alaskan, Indigenous Australian, Middle Eastern, biracial/multiracial, or non-White; this list is far from exhaustive and may vary between and within cultures. Recent genetic and immunological studies have suggested that cutaneous inflammatory disorders (atopic dermatitis, psoriasis, and hidradenitis suppurativa) and malignancies (melanoma, basal cell carcinoma, and cutaneous T-cell lymphoma) may have variations in their immunophenotype among SOC. Additionally, there is growing recognition of the substantial role social determinants of health play in driving health inequalities in SOC communities. It is critically important to understand that social determinants of health often play a larger role than biologic or genetic factors attributed to "race" in health care outcomes. Herein, we describe the structural, genetic, and immunological variations and the potential implications of these variations in populations with SOC. This article underscores the importance of increasing the number of large, robust genetic studies of cutaneous disorders in SOC to create more targeted, effective therapies for this often underserved and understudied population. Part II of this CME will highlight the clinical differences in the phenotypic presentation of and the health disparities associated with the aforementioned cutaneous disorders in SOC.

Skin of color (SOC) patients are projected to comprise the majority of the population by 2044, yet knowledge gaps in the clinical presentation and treatment of both common and uncommon dermatologic conditions in skin of color persist. Improved awareness of disparities that disproportionately impact SOC patients is necessary to address health inequity in the field of dermatology. The first part of this CME discussed structural, genetic, and immunophenotypic differences in SOC in common inflammatory disorders as well as cutaneous malignancies. The second part of this CME highlights clinical differences in the phenotypic presentation of the inflammatory disorders of atopic dermatitis, psoriasis, and hidradenitis suppurativa as well as the cutaneous malignancies of melanoma, basal cell carcinoma, and cutaneous T-cell lymphoma. Health disparities associated with each of these conditions are also discussed.

Lichen planus pigmentosus (LPP) is a rare variant of lichen planus presenting most commonly in middle-aged patients of color and characterized by the insidious onset of violaceous, brown, or grayish patches on photo distributed areas. Currently, there is limited data regarding the efficacy of treatments for LPP. We, therefore, sought to provide an analysis of current treatment protocols for this condition.

BACKGROUND: There is limited literature regarding potential disparities in nonmelanoma skin cancer for patients with skin of color. OBJECTIVE: Use the sizes of Mohs micrographic surgery defects to examine disparities in nonmelanoma skin cancer among Hispanic/Latino patients with a secondary aim to examine the effect of insurance type. METHODS: We conducted a multicenter retrospective study using data from 3 major institutions in Los Angeles County. A total of 3486 Mohs micrographic surgeries of basal cell, squamous cell, and basosquamous cell carcinomas were analyzed. RESULTS: Mohs micrographic surgery defect sizes were 17% larger among Hispanic/Latino patients compared with non-Hispanic White patients. More notably, when comparing defect sizes of squamous cell carcinomas to those of basal cell carcinomas, defects were 80% larger among Hispanic/Latino patients compared to non-Hispanic White patients who had 25% larger defect sizes. Compared to patients with Medicare, patients with health maintenance organization and Medicaid/health maintenance organization had 22% and 52% larger defect sizes, respectively, whereas patients with preferred provider organization, had 10% smaller defect sizes. LIMITATIONS: The data included were from a single county population. CONCLUSION: Disparities regarding nonmelanoma skin cancer exist between patients with skin of color and White patients. Patients and the medical community need to be cognizant that skin cancer can develop in patients regardless of their race and ethnicity.

Postinflammatory hypopigmentation is an acquired form of hypopigmentation that occurs secondary to an exogenous or endogenous insult to the skin. It can occur in all skin phototypes but is more visually apparent in skin of color. Due in part to greater attention given to its counterpart, postinflammatory hyperpigmentation, there is a dearth of literature describing this entity and treatment options remain limited. This review provides a comprehensive update on the pathogenesis, diagnostic evaluation and treatment of postinflammatory hypopigmentation, with a focus on newly reported treatment modalities.

Frank-Ter Haar syndrome (FTHS, MIM #249420) is a rare skeletal dysplasia within the defective collagen remodelling spectrum (DECORS), which is characterised by craniofacial abnormalities, skeletal malformations and fibrotic soft tissues changes including dermal fibrosis and joint contractures. FTHS is caused by homozygous or compound heterozygous loss-of-function mutation or deletion of SH3PXD2B (Src homology 3 and Phox homology domain-containing protein 2B; MIM #613293). SH3PXD2B encodes an adaptor protein with the same name, which is required for full functionality of podosomes, specialised membrane structures involved in extracellular matrix (ECM) remodelling. The pathogenesis of DECORS is still incompletely understood and, as a result, therapeutic options are limited. We previously generated an mmp14a/b knockout zebrafish and demonstrated that it primarily mimics the DECORS-related bone abnormalities. Here, we present a novel sh3pxd2b mutant zebrafish, pretzel, which primarily reflects the DECORS-related dermal fibrosis and contractures. In addition to relatively mild skeletal abnormalities, pretzel mutants develop dermal and musculoskeletal fibrosis, contraction of which seems to underlie grotesque deformations that include kyphoscoliosis, abdominal constriction and lateral folding. The discrepancy in phenotypes between mmp14a/b and sh3pxd2b mutants suggests that in fish, as opposed to humans, there are differences in spatiotemporal dependence of ECM remodelling on either sh3pxd2b or mmp14a/b The pretzel model presented here can be used to further delineate the underlying mechanism of the fibrosis observed in DECORS, as well as screening and subsequent development of novel drugs targeting DECORS-related fibrosis.This paper has an associated First Person interview with the first author of the article.
