Elderly onset ulcerative colitis patients are likely to exhibit distinct features both at diagnosis and during follow-up. It is necessary to pay more attention to, and to conduct further studies on, this particular group of patients.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
