• Onset 20-30 years old
• DDX: Colonic angiodysplasia is an acquired lesion, usually of the ascending colon and cecum, affecting patients older than 60 years. Although patients infrequently present with massive blood loss, they most often present with signs and symptoms of anemia and syncope due to intermittent episodes of bleeding.
