Upper gastrointestinal tract bleeding may occur due to different reasons. The most common causes are peptic ulcer, acute gastritis, esophageal variceal bleeding, Mallory–Weiss syndrome, and bleeding due to malignancies.1 In this case, an 80-year old male patient with known coronary artery disease and no history of surgical. The patient developed hematemesis and after the hemoglobin decreased to 3 gr/dl, endoscopy revealed a gallstone with diamater of 3 cm in the distal pylorus and causing bleeding. A case of gallstones with a size of 3 cm, which was seated in the duodenal bulbus after cholecystoduodenal fistula and caused mucosal bleeding due to trauma, is presented.
