 Mesenchymal tumors, primarily leiomyoma and granular cell tumor of the esophagus, show submucosal tumor(SMT)-like morphology, whereas esophageal cancer also shows SMT-like morphology. When the SMT-like esophageal cancer is not exposed on the surface, it is difficult to diagnose cancer by usual endoscopic examination or EUS, as well as biopsy. It is necessary to distinguish between SMT and SMT-like esophageal cancer using EUS. Our study focused on whether the first layer of the lesion can be recognized consecutively to distinguish SMT from SMT-like esophageal cancer.

 Out of the mesenchymal tumors, 1/9 layer was clearly recognized in all cases in 3 cases of leiomyoma. In 3 GCT cases, 1/9 layer was recognized, but it was partially thinned. SMT-like esophageal cancer 11 cases, 1/9 layer was torn and thinned in all cases. It is considered that there is a possibility of leading to qualitative diagnosis distinguishing SMT-like tumor and SMT in focusing on 1/9 layer by EUS.
