The histologic examination reveals that lymphangiomas are composed of endothelium-lined spaces that contain a eosinophilic protein-rich fluid. They usually present as polypoid lesions because they are originated from submucosal layer. By endoscopy, they appear as smooth, soft, polypoid submucosal mass.
