Acute onset of dermatomyositis presenting in pregnancy with rhabdomyolysis and fetal loss.

We report a case of acute onset of dermatomyositis with rhabdomyolysis and myoglobinuria, which presented in the 14th week of pregnancy and resulted in spontaneous abortion of the fetus. The diagnostic work up for an underlying disease was negative and the histologic examination confirmed the diagnosis of dermatomyositis, which subsequently improved with corticosteroids.
