Higher magnification of the previous image showing intestinal metaplasia with scattered goblet cells. Barrett esophagus is found in almost 10% of individuals with symptomatic GERD. The typical patient is a white male between the ages of 40 and 60. It may also be seen in children with cystic fibrosis. On endoscopy, it appears as sharply demarcated areas of red, velvey mucosa extending proximally from the gastroesophageal junction.
