title: Observations of different patterns of dysplasia in barretts esophagus - a first step to harmonize grading.
abstract: We reviewed a set of cases of early neoplasia (low grade / high grade dysplasia / IEN and mucosal carcinoma) to reach better defined criteria for subtypes of dysplasia/differentiation in the columnar lined (Barretts) esophagus. We discuss criteria that we categorized for recognizing low and high-grade dysplasia and mucosal carcinoma in patterns of neoplasia that we regarded as intestinal, gastric and mixed.
