Purpose
Accurately diagnosing and assessing psoriasis in people with darker skin can be challenging, as many dermatology references often fail to capture the full range of presentations in diverse skin types. This educational tool aims to address these gaps, providing healthcare professionals, students, and researchers with a comprehensive visual reference to enhance diagnostic accuracy and promote equitable care for patients with diverse skin types.
Background
The International Psoriasis Council (IPC) conducted a global survey among dermatologists treating patients with diverse skin types to develop this tool. The questionnaire revealed key differences in psoriasis characteristics across sub-populations—plaque color, scaling, and morphology—commonly underrepresented in dermatology resources. For instance, erythema in darker skin may appear more purple than pink, and post-psoriasis pigmentation changes are more prevalent. These findings, combined with expert feedback, shaped the key characteristics included in this tool.
The images included in this tool highlight these differences and emphasize high-impact areas, such as the scalp, genitals, nails, palms, and soles, where psoriasis may present uniquely in individuals with darker skin. Additionally, presentation of psoriasis phenotypes can vary across different skin types, influencing diagnosis. Recognizing the potential for delayed or misdiagnoses due to barriers in care, the gallery includes images of neglected or undertreated psoriasis cases, offering clinicians a clearer view of what may be overlooked in clinical practice.
To provide accurate global representation, we have collected images from all regions – including Africa, Asia, Latin America, Europe, and North America – ensuring a range of diverse skin types, psoriasis types, and clinical settings. This variety enriches the tool, making it an essential resource for improving diagnostic accuracy and care equity worldwide for patients with diverse skin types.
Acknowledgment
We would like to extend our gratitude to the members of IPC’s global network who have generously contributed their photographs and expertise. Their invaluable support is helping to improve psoriasis care for patients with diverse skin types and in all regions.
