Duodenal hemorrhage and dermal vasculitis associated with mixed connective tissue disease.

We describe a 23-year-old woman with mixed connective tissue disease (MCTD) who developed duodenal bleeding responsive to treatment with corticosteroid and recurrent skin eruptions due to leukocytoclastic vasculitis. The endoscopic findings revealed patchy, reddened, edematous, friable mucosa with scattered small ulcers and oozing of blood in the second portion of the duodenum. Endoscopic pictures from the onset to healing are presented. This appears to be the first recorded occurrence of such findings in MCTD.
