Abstract
Background
Calcinosis cutis is usually seen in long standing and untreated cases of juvenile dermatomyositis.
Case characteristics
7-year-old girl with severe calcinosis cutis who developed cutaneous ulceration, rash and myopathy.
Observation
Myopathic changes in EMG, muscle edema in MRI, elevated muscle enzymes and Jo-1 positive antibodies.
Outcome
Treatment with prednisolone and methotrexate resulted in improvement of the lesion.
Message
Calcinosis cutis may be a presenting feature of juvenile dermatomyositis even in the absence of characteristic findings of rash and weakness.
