Abstract
An apparently novel entity, diffuse hemorrhagic gastroenteropathy (DHG), in a 70-year-old female who had an unremitting course of chronic gastrointestinal blood loss for 3 years requiring transfusion of more than 200 units of packed red blood cells over this period is reported here. Endoscopy showed diffusely hemorrhagic mucosa in the stomach, duodenum, and small bowel. Full-thickness biopsy of the stomach and small intestine revealed luminal narrowing of capillaries and post-capillary venules within the lamina propria due to swelling and some proliferation of the endothelial cells with margination and emigration by neutrophils as well as partial occlusion of some vessels by fibrin thrombi. DHG may represent a new entity characterized by mucosal hemorrhage due to local mucosal ischemia of the gastrointestinal tract secondary to a small vessel "vasculopathy" apparently restricted to this site.
