Zusammenfassung: <jats:sec><jats:title>Objective</jats:title><jats:p>To investigate clinical manifestations of juvenile systemic sclerosis (<jats:styled-content style="fixed-case">SS</jats:styled-content>c; scleroderma), including disease characteristics and patient quality of life, using the multinational Childhood Arthritis and Rheumatology Research Alliance (<jats:styled-content style="fixed-case">CARRA</jats:styled-content>) Legacy Registry.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>Patients with juvenile <jats:styled-content style="fixed-case">SS</jats:styled-content>c were prospectively enrolled between 2010 and 2013. The diagnosis of juvenile <jats:styled-content style="fixed-case">SS</jats:styled-content>c was determined by the enrolling pediatric rheumatologist, with the requirement for disease onset prior to age 18 years. Collected data included demographics, disease characteristics, medication exposure, and quality of life metrics.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>In total, 64 patients with juvenile <jats:styled-content style="fixed-case">SS</jats:styled-content>c were enrolled a median of 3.6 years after disease onset, which occurred at a median age of 10.3 years. The most common organ manifestations were dermatologic and vascular, followed by musculoskeletal, gastrointestinal, and pulmonary; in 38% of patients, ≥4 organ systems were affected. Patients with juvenile <jats:styled-content style="fixed-case">SS</jats:styled-content>c had significantly more disability at enrollment compared with <jats:styled-content style="fixed-case">CARRA</jats:styled-content> Legacy Registry patients with juvenile idiopathic arthritis, dermatomyositis, or systemic lupus erythematosus. Although physician‐reported measures correlated most closely with arthritis, dermatologic manifestations, and pulmonary manifestations, poor patient‐reported measures were associated with gastrointestinal involvement. During &gt;50 person‐years of follow‐up, most organ manifestations remained stable, and no mortality or development of new solid organ involvement after enrollment was reported.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>In the first multicenter prospective cohort of patients with juvenile <jats:styled-content style="fixed-case">SS</jats:styled-content>c in North America, the disease burden was high: multiorgan manifestations were common, and functional disability was greater than that observed in patients with other childhood‐onset rheumatic diseases. Gastrointestinal involvement had the greatest impact on quality of life.</jats:p></jats:sec>
