    Abstract:
    INTRODUCTION: 5% of patients with sarcoidosis are affected by neurological complications, of which myopathy is one of the least frequent. We report the clinical course and therapeutic response of two patients with sarcoid myopathy. CASE REPORTS: We observed two females aged 63 and 55 who were previously diagnosed with sarcoidosis, which in one case was cutaneous and ophthalmic and in the other pulmonary. Both were asymptomatic from a systemic point of view when they visited the Neurology department. Both patients developed chronic myopathy (with a history of 9 months and 6 years), which was predominantly proximal, painful and both of them had normal or slightly high levels of creatine phosphokinase. The EMG was clearly myopathic in the two patients. A muscle biopsy showed a mononuclear-cell infiltrate with the formation of non-caseating granulomas. Both patients were treated with prednisone, although the therapeutic response was different in each case. One of the patients showed an important improvement in just a few days, while in the other case the disease remained stable, despite adding, first, azathioprine and later methotrexate to the treatment. CONCLUSIONS: Sarcoidosis can cause chronic, predominantly proximal, myopathy, and chiefly affects females over 50 years of age. The therapeutic response to steroids and immunosuppressants varies from case to case.
