Abstract
-
Polymyositis is an inflammatory, autoimmune disease of the skeletal muscle characterized by
symmetrical, proximal muscle weakness, elevated muscle enzymes, and characteristic features on
electromyogram and muscle biopsy. The kidneys are generally spared and myoglobinuric renal
failure is very rare in polymyositis. There have been infrequent reports of polymyositis
developing myoglobinuric renal failure secondary to rhabdomyolysis. The flare-up may occur in
polymyositis, usually manifest within several weeks to months of achieving a remission. But,
rhabdomyolysis and myoglobinuric renal failure was a very rare feature of the relapse of
polymyositis. We present a case report of patient with polymyositis who initially presented and
relapsed as rhabodomyolysis that lead to myoglobinuric, oliguric renal failure and required
transient dialytic support.
