Introduction: Juvenile localized scleroderma (jlSc) usually responds well to treatment with methotrexate or mycophenolate. In case of nonresponse or partial response, tocilizumab (TOC) appears to be a promising option. Methods: Participants of the Pediatric Rheumatology Email Board were asked to report patients with jlSc treated with TOC. Results: Six centers responded and reported 11 patients. The mean age at disease onset was 5.5 years. Disease duration at time of the initiation of TOC was 4.5 years. A total of 5 patients had linear subtype, 2 Parry Romberg syndrome, and 1 morphea en coup de sabre. Three had a generalized subtype, 2 a mixed subtype, and 1 a limited subtype/morphea. Before starting TOC, 10 of 11 patients received methotrexate, 7/11 combination methotrexate and mycophenolate, 1 abatacept, and 1 antitumor necrosis factor therapy. The indications for starting TOC were: (i) an increase in the score of the Localized Scleroderma Activity Index (mLoSSI) in 9 patients; and (ii) evidence of increased extra-cutaneous activity in 2 patients. The mean duration of TOC therapy was 14.75 months. Three of 11 patients received TOC as monotherapy, and 8/11 as combination therapy. Therapy success was reflected by a decreased mLoSSI in 9/11 patients, no new lesion occurrence, and - with Parry Romberg syndrome subtype - no increase in facial atrophy. In 8/8 patients, both the physicians' and patients' global assessment of disease activity decreased. In 3/3 patients, the number of active joints decreased. The mean modified Rodnan skin score decreased from 8.7 to 5.6. Conclusions: In this small cohort of patients, TOC seems to be a promising rescue medication.
