Most patients experienced at least one extracutaneous manifestation (70%), most commonly musculoskeletal (57%), followed by neurological (46%), and ophthalmological (11%). Those with musculoskeletal extracutaneous manifestation have significantly abnormal inflammatory and antibody laboratory values. Of patients with 1-year follow-up, a majority were treated with systemic therapy and globally improved with significant reduction in both modified Localized Scleroderma Skin Index ( p\u2009&lt;\u20090.001) and Localized Scleroderma Damage Index ( p\u2009=\u20090.001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The study highlights need for earlier recognition of juvenile-onset localized scleroderma after demonstrating the delay in diagnosis and frequent extracutaneous manifestations with significant disease burden in a juvenile-onset localized scleroderma cohort.
