 The esophagus contains various atypia even within the same lesion, and many secondary changes occur because of inflammation. Therefore, diagnosis should be based on a comprehensive evaluation and not on a single finding. We reviewed the morphological and immunohistological properties of lesions that differentiate them from tumors. Although Ki-67 is a useful marker, many cautions must be taken. In recent years, many follow-up cases after definitive chemoradiation have been reported, and caution is required. Although tumors and nontumors are difficult to differentiate clearly in routine diagnosis, endoscopists and pathologists must reach a consensus on the diagnostic term so that patients are not disadvantaged.
