 As there are usually no symptoms associated with esophageal benign tumors, they are often found first by endoscopy or double-contrast radiographic examination. Whereas most of them need no treatment but only observation, some cases need differential diagnosis from malignant lesions, and few cases are indicated the treatment.

 Benign esophageal tumors are classified into epithelial tumor and non-epithelial tumor. The diagnosis of benign epithelial tumor is performed easily because of the characteristic appearance. On the other hand, the differential diagnosis of non-epithelial tumor covered by normal epithelium was hard to achieve by conventional endoscopy, and use together with EUS, MRI and CT. To determine the diagnosis, pathological examination by a biopsy specimen of the submucosal tissue is essential.

 When an esophageal benign tumor is detected, it should be defined by its shape, size, color, solidity, surface appearance, presence of depressions, ulcer, or multiple lesions, etc. The findings of a size over 3cm, irregular surface, accompanied by depressions or ulcerations, and features of rapid growth frequently represent malignant manifestations of these lesions.
