Juvenile Dermatomyositis with Cutaneous Calcinosis: a case report

Abstract

Juvenile dermatomyositis is a rare autoimmune myopathy. We report the case of an 11-year-old boy with a 7-year history of pruritic papules that became generalized, associated with proximal muscle weakness, arthralgia, and intermittent fever. Examination showed periorbital edema with hyperpigmentation, Gottron’s papules, calcified papulonodules, and diffuse cutaneous atrophy with a sclerodermiform aged appearance. Muscle enzymes were elevated, and histology revealed calcium deposits. Clinical outcome under prednisone was favorable. This case highlights a severe, long-standing presentation.
