title: Streptococcal myositis as a complication of juvenile dermatomyositis.
abstract: The infection of muscle is an infrequent condition. We report on a patient with a juvenile form of dermatomyositis who developed infectious myositis caused by Streptococcus pyogenes. The inflammatory myopathy probably favoured the colonization of muscle during a bacteremia related to the skin lesions. The main forms of streptococcal myositis, which can currently be differentiated by means of imaging techniques, are discussed in addition to its treatment and prognosis.
