Endoscopic appearance of environmental enteropathy. Endoscopic view of second part of the duodenum showing villi with characteristic changes of environmental enteropathy: fusion of villi so that instead of a finger-like appearance they take on a leaf-shaped appearance. Sometimes villous fusion goes further and takes on a cerebriform (sulcus and gyrus) appearance. Endoscopic image from Endoscopy Unit, University Teaching Hospital, Lusaka (P. Kelly).
