Dieulafoy’s lesion of the colon: management of this unusual location

Dieulafoy’s lesion (DL) is a rare but potentially life-threatening vascular anomaly characterized by the presence of an abnormally dilated artery in the submucosa of the gastrointestinal tract. Although the stomach is the most common site, colonic involvement is rare, making both diagnosis and management challenging. This article reports a case of colonic Dieulafoy’s lesion in a 74-year-old patient presenting with melena and discusses current strategies for endoscopic management. Early endoscopic intervention is essential for diagnosis and treatment, with mechanical methods such as the application of hemostatic clips being preferred to prevent recurrence.
