Abstract: A 64-year-old man involved in a low-speed vehicle crash was found at autopsy to have altered blood extending from his stomach to his rectum. Within the stomach a small arterial vessel opened onto the mucosa of the posterior wall of the antrum adjacent to the pylorus with no adjacent mucosal ulceration or malignancy. Histologic sections showed the typical appearances of a Dieulafoy lesion with a tortuous small arteriole within the submucosa extending to the gastric lumen with an overlying cap of recently formed clot. There were no injuries attributable to the vehicle collision. Death was due to a bleeding Dieulafoy lesion of the stomach with a background of cardiomegaly. Dieulafoy lesion of the stomach is a rare disorder accounting for only 1-2% of cases of acute gastrointestinal hemorrhage. Although its pathogenesis is poorly understood it is capable of producing life-threatening bleeding, as in the present case. The small size of the lesion may make it difficult to identify at the time of autopsy.
