Submucosal gastric heterotopia presenting as an upper esophageal nodule
JOURNAL OF SURGICAL CASE REPORTS(2021)
摘要
Esophageal gastric heterotopia (GH), the presence of differentiated gastric tissue in the esophagus, is estimated in up to 14% of populations worldwide and has always been reported on the surface of the esophagus, where it is also known as inlet patch. However, submucosal GH, in any tissue, is a rare finding. We report the case of a 50 year-old male presenting with chronic cough, heartburn and raspy vocalizations. Endoscopic examination showed a single 7 mm esophageal nodule, 20 cm from the incisors, interpreted as a submucosal mass. Pathologic examination of the endoscopically excised nodule showed well-differentiated gastricmucosa within the submucosa underneath the overlying squamousmucosa, consistent with submucosal GH. This case raises the awareness of an atypical presentation and location of GH seen as a submucosal mass on endoscopy.
