[Rhabdomyolysis, acute renal insufficiency and hypercalcemia]

Acute renal failure is a severe and frequent complication of rhabdomyolysis. During the early polyuric phase, hypercalcemia is observed in around 30% of cases. The principal mechanism is the liberation of calcium from areas of muscular necrosis. Two cases of toxic rhabdomyolysis with secondary hypercalcemia are described.
