Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal (GI) tract, but the lesion occurs rarely in the esophagus. Although only 10∼30% of GISTs are malignant at the time of diagnosis, many reports show that it is difficult to predict the prognosis and underlying potential of non-malignant ones. Thus, the surgical removal of GISTs is even being proposed as a standard treatment. Recently the endoscopic removal of submucosal tumors of the GI tract is being done in popular, but it has been still considered as both difficult and risky to resect a tumor originating from the muscularis propria layer using the endoscopic methods. Herein, we report a case of an incidentally found submucosal tumor originating from the muscularis propria treated with an endoscopic submucosal dissection method which was performed after a preceding mucosectomy using a transparent cap. The mass turned out to be an esophageal GIST. (Korean J Gastrointest Endosc 2009;39:364-368)
