This is a Dieulafoy’s lesion, a dilated aberrant submucosal vessel which erodes the overlying epithelium in the absence of a primary ulcer. The submucosal artery is 1-3mm (mucosal capillaries 0.1-0.3mm), usually located in the upper stomach but can be found anywhere in the GI tract. Etiology is unknown, but they are considered congenital.
