[Muscular sarcoidosis: a case report of muscle and fascia involvement and literature]

Abstract

Introduction: 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.

Case report: 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.

Conclusion: 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.
