 As mucosal esophageal cancer has almost no lymph node metastasis and has a pretty good prognosis, we would like to call only these lesions“early esophageal cancer”. Endoscopically, m cancer is usually revealed as type Ⅱ lesion, but, in today's classification, it can not be distinguished whether Ⅱa and Ⅱc lesions are m or sm cancer. Because of this, 86 superficial esophageal cancer lesions were reexamined. As a result, it was found that all Ⅱb type lesions, Ⅱc lesions with a smooth or particularly fine granular surface and Ⅱa lesions with a sharp tumor edge were located only in the mucosa. However Ⅱc lesions with a granular, nodular or roughly irregular surface and Ⅱa lesions with epithelial overlapping of the tumor demonstrated sm cancer. The features of sm cancer are discussed here again.
