Acute myositis and dermatitis as the initial presentation of sarcoidosis.

We report a case of a patient who presented with symptoms of acute debilitating proximal muscle weakness, which mimicked acute polymyositis, accompanied by a hypopigmented papular rash. The histology of the skin and muscle demonstrated sarcoidosis. A review of the literature of acute sarcoid myositis and the various other myopathies of sarcoidosis is presented.
