Extragenital lichen sclerosus et atrophicus (LSA) is rare in children. We report a 7-year-old girl with multiple whitish, wrinkled, bizarrely shaped plaques over the trunk and legs for two months. Dermoscopy revealed white structure-less areas, follicular plugging, and a comet-tail appearance, consistent with LSA. Topical fluticasone propionate 0.05% cream led to marked improvement. Pediatric extragenital LSA may mimic vitiligo, morphea, and pityriasis alba, often causing diagnostic delays. Early recognition and therapy are important to prevent progression and cosmetic sequelae.
