 We present the clinicopathological features of benign esophageal tumors and tumor-like lesions and explain their characteristics by reviewing the literature. When these lesions are found clinically, due to a feeling of swallowing or difficulty in swallowing, it is crucial to differentiate benign lesions from malignant tumors.In contrast, there are also asymptomatic diseases, such as papillomas, that are incidentally found by endoscopy and do not require active treatment. Macroscopically, esophageal lesions are classified into three groups:submucosal tumors, lesions protruding into the lumen, and lesions present in the esophageal wall. Knowledge of the clinicopathological characteristics of each lesion could aid in differential diagnosis. Furthermore, some of these lesions are associated with malignant tumors or hereditary diseases ; hence, attention should be paid not only to the diagnosis of benign lesions but also to their relationship with other diseases.
