Gencosmanogle et al reported a Helicobacter pylori-negative hyperplastic polyp which was treated by polypectomy. Since hyperplastic polyps causing symptoms such as obstruction or bleeding are usually 
treated by polypectomy, an important point of the present case was if this case was truely 
Helicobacter negative. Examinations relating this point were insufficient. Minor 1. Urea breath test and test for serum Helicobacter pylori should be performed. 
2. Histological examinatin of greater cunvature of antrum and body of stomach should have been 
done to assess gastritis, atrophy, and Helicobacter pylori infection. Since it is well known that Helicobacter pylori does not exist on lesions such as hyperplastic polyp, authors should describe the site of examination in RUT and giemsa staining. 
3. Prevalence of Helicobacter pylori infection in gastric hyperplastic polyp should be reviewed.a
