An esophageal submucosal gland duct adenoma is a rare benign disease. We report a 58-year-old man who presented with an esophageal submucosal tumor on health screening endoscopy. The endoscopic examination showed a round elevated lesion with central depression at the mid-esophagus. On endoscopic ultrasonography, an anechoic lesion with some hyperechoic septal structures measuring 8 mm in the largest diameter was observed in the third layer. We resected the lesion endoscopically. Histologically, there were several dilated gland ducts, with proliferation of the inner epithelial and outer myoepithelial cell layers. These findings were compatible with a submucosal gland duct adenoma of the esophagus. (Korean J Med 2012;83:476-479)
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.
