[Muscular sarcoidosis: apropos of a case].

We report the case of a 75-year old woman presenting sarcoid myopathy with pseudohypertrophy and skin involvement. Muscular biopsy confirmed the diagnosis of sarcoidosis. Symptomatic muscle involvement in sarcoidosis is rare. Three forms are described: myopathic, myositic and nodular. The relevance of imaging techniques is reviewed. Treatment is based on corticotherapy which is less efficient in myopathic form and in this case we had to use methotrexate with success.
