Dieulafoy lesion is an abnormally large calibered submucosal artery associated with a minute mucosal defect in the gastrointestinal mucosa. It is a rare cause of profuse, but intermittent gastrointestinal bleeding. The lesion is usually located in the stomach, although it may occur anywhere in the gastrointestinal tract. Dieulafoy lesion is extremely rare in the neonates. We report two newborn infants with a gastric Dieulafoy lesion which was treated by endoscopic epinephrine injection therapy without complication and recurrence.
