Exploring Pediatric Dermatology in Skin of Color: Focus on Dermoscopy.

This literature review aims to comprehensively evaluate the clinical and dermoscopic presentations of common pediatric diseases among children with skin of color (SoC) while also addressing potential variations based on racial backgrounds. This review encompasses various conditions, such as nevi subtypes, viral infections, infestations, and inflammatory dermatoses, as well as hair diseases and abnormal vascular formations, occurring in pediatric populations. Overall, we identified 7 studies on nevi subtypes, 24 studies on skin infections, 6 on inflammatory dermatoses, 10 on hair diseases and disorders, and 14 on miscellaneous disorders that also satisfied our SoC- and race-specific criteria. In case of no results, we assumed that dermoscopic findings are similar between SoC adults and children, confirming the hypothesis with our cases of dark-skinned Indian child patients. Inflammatory dermatoses such as psoriasis, eczema, and cutaneous mastocytosis, as well as skin infections like cutaneous leishmaniasis, appear with brownish backgrounds or exhibit dark structures more frequently than the respective dermoscopy images of Caucasian populations. Dermoscopy traits such as erythema in tinea capitis are uncommon or even absent on a dark-colored scalp, while a dark skin tone often obscures many characteristic features, such as dark and yellow dots in alopecia areata and even parts of an intradermal parasite in the case of scabies. Race-specific traits were also observed, such as corkscrew hair in tinea capitis, primarily seen in patients of African origin. Many dermoscopic images are consistent between SoC and non-SoC in various skin lesions, including vascular anomalies, juvenile xanthogranuloma, mastocytoma, and viral skin lesions like molluscum contagiosum, as well as in various hair disorders such as trichotillomania, while tinea capitis displays the most diverse reported dermoscopic features across SoC- and race-specific studies.
