Scleroderma in childhood is rare and variable in clinical presentations.
Localized scleroderma is the most common and can present at any age, with the appearance of a patch of abnormal skin (called morphoea) and which, when untreated, generally follows a course of active expanding disease, fibrosis and eventual softening with some “remission”.
The functional and cosmetic impact can be profound, as the lesions may interfere with growth of a limb and subcutaneous tissues (of the face or a limb).
Systemic scleroderma is extremely rare in children and includes progressive diffuse fibrous changes of the skin and fibrous changes involving internal organs - most commonly lungs, gastrointestinal tract, heart and kidneys - with a significant mortality.
Systemic scleroderma is slowly progressive, has a guarded prognosis and requires potent immunosuppression.
Management includes aggressive treatments (corticosteroids and methotrexate, as well as other immunosuppressives) with the aim of limiting severe disfigurement and disability.
