We report on a 57-year-old woman with polymyositis who on two occasions presented with rhabdomyolysis and myoglobinuria, with resultant oliguric acute renal failures, the second episosde of which required haemodialysis.
Polymyositis is a rare and gradually progressive autoimmune inflammatory disease of skeletal muscle that is characterized by muscle weakness, usually proximal and symmetric, elevated muscle enzymes, and distinctive findings on electromyography and muscle biopsy [1]. The disease may be associated with infections or with other collagen vascular diseases, such as Sjögren's syndrome and sarcoidosis [1].
Rhabdomyolysis is a term that refers to disintegration of striated muscle, which results in the release of muscle cell constituents, in particular myoglobin, into extracelluar fluid and the circulation. The released myoglobin is filtered by glomeruli and reaches the tubules, where it may cause obstruction and renal dysfunction [2]. The main causes of rhabdomyolysis
