Complex Presentation of a Dieulafoy Lesion in a Geriatric Patient with Multiple Comorbidities.

Dieulafoy lesions (DL) consist of tortuous, thick-walled submucosal arteries that protrude through a small mucosal defect, often surrounded by otherwise normal mucosa. They are commonly located in the proximal stomach, particularly along the lesser curvature and near the esophagogastric junction, typically within 5 cm. However, they can also occur in various other regions of the GI tract, including the esophagus, duodenum, and colon.
