Gastrointestinal Vasculitis in Adult Patient With Dermatomyositis Presenting as Hematemesis.

Dermatomyositis (DM) is an inflammatory disease of the muscles and skin. Severe gastrointestinal (GI) involvement, characterized by GI bleeding and perforation secondary to underlying vasculopathy, is rarely seen. We describe a case of newly diagnosed DM in a 75-year-old woman who presented with a rash and muscle weakness. She then had sudden onset of hematemesis and was found to have duodenal ulcers due to leukocytoclastic vasculitis from her DM. Our aim was to highlight the need for recognition of GI involvement in adults with DM.
