Dieulafoy's lesion of the esophagus as a probable complication of Takayasu's arteritis.

Dieulafoy's lesion is an abnormal submucosal artery in the gastrointestinal tract characterized by massive gastrointestinal bleeding. We describe a patient who developed Dieulafoy's lesion of the esophagus in the course of isolated pulmonary Takayasu's arteritis. Angiographic findings indicated a relationship between pulmonary arterial involvement of Takayasu's disease and Dieulafoy's lesion of the esophagus. This observation represents the first report of the association between Takayasu's arteritis and Dieulafoy's lesion of the esophagus.
