title: [Muscular sarcoidosis: a case report of muscle and fascia involvement and literature].
abstract: BACKGROUND
  Muscular involvement in sarcoidosis is noted in 50 to 80% of the patients when systematic muscle biopsies are carried out. Nevertheless, symptomatic forms are rare and three different types can be distinguished: nodular, chronic myopathy and acute myositis.
  
  
  METHODS
  We report a 43-year-old man who presented with sarcoidosis involving in muscles, fascia and articulations. The diagnosis of sarcoidosis was supported by magnetic resonance imaging and positron emission tomography imaging and confirmed by a muscle biopsy. Clinical manifestations resolved with corticosteroids and methotrexate.
  
  
  CONCLUSIONS
  We review 23 cases of sarcoidosis myosistis most similar to ours. The commonest presentation is the involvement of the proximal limb muscles in association with elevated serum muscle enzymes.
