 The superficial esophageal cancer with the appearance of submucosal tumor include small cell type undifferentiated carcinoma, adenoid cystic carcinoma, basaloid carcinoma and adenosquamous carcinoma as well as some cases of adenocarcinoma and moderately differentiated or poorly differentiated squamous cell carcinoma. Carcinoid tumor, leiomyosarcoma and metastatic carcinoma can show the similar appearance but rarely.

 For the endoscopic diagnosis of these submucosal type of superficial carcinoma in esophagus, iodine staining and toluidine blue staining are useful. The important points to observe the lesion are as follows; ① existence of intraepithelial spread or not, ② the shape of protrusion the tumor, ③ irregular of the tumor surface, ④ the thickness of the covering epithelium, ⑤ the features of the central depression.

 We described in detail on the differential diagnosis of the superficial esophageal cancers with the appearance of submucosal tumor.
