Submucosal elevation is a general term for lesions in which the main lesion is covered in the same mucosa as the surrounding mucosa and protrudes into the intestinal lumen as a hemisphere or sphere. These lesions themselves are located below the submucosa, with the majority comprising non-epithelial tumors or tumorous lesions, but carcinoids, which are derived from the deep mucosal layer and inflammatory fibroid polyps (IFPs) must also be considered during differentiation.
