With the advent of modern techniques and the widespread use of gastric endoscopy, benign gastric wall lesions are now diagnosed more frequently and can be studied using the tissue obtained by biopsy or polypectomy. In the past, the diagnosis of gastric tumors was based on x-ray examination, but, in 1922, Schendler was the first to make an endoscopic-based diagnosis.[1] Note the image below.
