Juvenile localized scleroderma (jLS) is a chronic autoimmune and fibrosing disease associated with a high risk for functional impairment. Antifibrotic options are limited, so current treatment strategies are focused on disease activity control. Pediatric rheumatologists are in consensus on the need to treat with systemic immunosuppressants, in particular, methotrexate. However, more than 30% of patients fail initial methotrexate treatment. This review provides an update on current management and reviews reports on potential alternative treatments.

An overview of current treatment recommendations and its efficacy are discussed. Recent studies have identified several factors associated with likelihood of treatment response. These include time to initiation of treatment, certain subtypes, and extracutaneous involvement. Findings from recent reports of alternative systemic immunomodulators, including biologic medications, will be summarized.

Methotrexate treatment has greatly improved outcome for most jLS patients but a substantial portion have refractory cutaneous and/or extracutaneous disease. Treatment response factors are being identified, which could lead to improved management strategies. Recent studies provide further support on mycophenolate mofetil as an alternative treatment. Data on biologic therapies is encouraging, with data suggesting efficacy for many extracutaneous manifestations but more studies are needed to evaluate these and other options for jLS.
