Çakan M, Karadağ ŞG, Aktay Ayaz N. Complete and sustained resolution of calcinosis universalis in a juvenile dermatomyositis case with mycophenolate mofetil. Turk J Pediatr 2019; 61: 771-775. Juvenile dermatomyositis (JDM) is a rare, multisystemic, idiopathic vasculopathy mainly affecting the muscles and the skin. Gastrointestinal system, lungs, joints and heart may also be involved. Characteristic skin findings are heliotrope rash and Gottron papules but extensive skin involvement as large necrotic lesions are rarely reported. Calcinosis is one of the major issues in the long term. Delay in diagnosis, inadequate therapy at the initial phase, prolonged persistent disease activity are considered as major risk factors for the development of calcinosis. Treatment of calcinosis is also a major issue because no single treatment modality has been found to reproducibly stop or reverse calcification. A 5-year-old girl was admitted to our clinic with typical signs and symptoms of JDM. She was initially treated with high-dose corticosteroids, methotrexate and intravenous immunoglobulin (IVIG). Soon after, she developed necrotic ulcerative skin lesions and cyclosporine was added to her treatment regimen. By this treatment all muscle and skin manifestations were controlled but on the first year of follow-up she developed superficial calcification plaques on the upper extremities and calcinosis universalis like calcifications on the lower extremities. Calcifications did not respond to bisphosphonate (pamidronate) and IVIG treatment but mycophenolate mofetil resulted in rapid and sustained resolution of all calcification plaques.
