An unusual esophageal cancer.

ABSTRACT

This article describes an unusual case of a submucosal esophageal cancer, which should not typically arise and should not have the appearance that the present case had. This lesion was diagnosed only after endoscopic submucosal excavation was performed, given that the lesion was incorrectly diagnosed as an esophageal leiomyoma. The highlight of this case is that esophageal cancer can present as a benign submucosal tumor of the esophagus.
