Recurrent rhabdomyolysis as a manifestation of alcoholic myopathy. Report of a case.

A 38-year-old man experienced six severe episodes of rhabdomyolysis and two episodes of pharyngeal muscle weakness superimposed on chronic alcoholic myopathy and complicated by cardiomyopathy. A muscle biopsy specimen demonstrated sharply reduced levels of electrolytes despite normal serum values; presumably, these deficiencies were related to the pathogenesis of the recurrent rhabdomyolysis.
