Acute Hemorrhagic Myositis in Inflammatory Myopathy and Review of the Literature

Abstract

We describe two patients with dermatomyositis that presented with interstitial lung disease, positive V and Shawl sign who developed acute spontaneous abdominal/retroperitoneal bleed. Both patients expired despite aggressive treatment and resuscitation. Hemorrhagic myositis in these two patients with inflammatory myopathy is a very rare complication. The association of anti-Ro52 with this potentially very serious complication remains unclear. This potential relationship should be further evaluated in future studies.
