title: Superficial Esophageal Neoplasms Overlying Leiomyomas Removed by Endoscopic Submucosal Dissection: Case Reports and Review of the Literature.
abstract: The coexistence of an epithelial lesion and a subepithelial lesion is uncommon. In almost all such cases, the coexistence of these lesions appears to be incidental. It is also extremely rare to encounter a neoplasm in the surface epithelium that overlies a benign mesenchymal tumor in the esophagus. Several cases of a coexisting esophageal neoplasm overlying a leiomyoma that is treated endoscopically or surgically have been reported previously. Here, three cases of a superficial esophageal neoplasm that developed over an esophageal leiomyoma and was then successfully removed by endoscopic submucosal dissection are described.
