Description

A 70-year-old man with a gastric lesion was referred to our hospital because of an unusual pedunculated lesion in the gastric body. Endoscopic ultrasound showed scattered cystic lesions within a heterogeneous area confined to the submucosal layer. Endoscopic mucosal resection was performed to obtain a precise diagnosis, as well as for removal. The lesion was histopathologically diagnosed as a heterotopic submucosal gland. We herein describe this rare type of gastric polyp and provide a literature review.<br>
