Abstract Objectives Cutaneous manifestations of Systemic Autoimmune Rheumatic Disease -Interstitial Lung Disease (SARD-ILD) are clinically useful diagnostic features that can support early diagnosis and management. However, medical education resources often lack diversity in representing skin tones which lead to inequities in healthcare delivery. Our study aimed to quantify the proportion of skin tones represented in medical literature that depict cutaneous features relevant to SARD-ILD. Methods A structured search of medical resources was conducted with the support of North Bristol NHS Trust Library and Knowledge Service. We systemically reviewed images of cutaneous signs associated with systemic sclerosis, dermatomyositis and vasculitis. Images that did not depict these conditions were excluded. Each image was assigned a Monk’s skin tone (MST) scale score (1–10). A Chi Squared goodness of fit analysis was used to establish whether the distribution of images was equal. Results Sixteen e-resources and 26 textbooks were analysed, yielding 790 images: there were 190 depicting systemic sclerosis, 401 dermatomyositis and 199 vasculitis. The Chi Squared indicated a significantly unequal distribution of images across skin tones (p 0.001), a pattern that persisted across all conditions. Furthermore, there was no significant improvement in skin tone representation from 2009 to 2022 (median skin tone category 1–2). Conclusion There is persistent under-representation of people of global majority in educational resources, despite evidence of higher disease prevalence and severity among individuals with darker skin tones. Increasing the inclusion of diverse skin tones in medical imagery is essential to enhancing diagnostic accuracy, reducing health disparities, and improving clinical outcomes.
