1 Normal Squamous Epithelium	Flat Cells with bright intrapapillary capillary loops
2 Non-dysplastic Barrett's Esophagus	Uniformed villiform architecture with dark goblet cells
3 Barrett's esophagus with high-grade dysplasia	Villiform structures with dark, irregular and thick borders
4 Adenocarcinoma	Disorganized villiform architecture and dilated irregular vessels
