Here, we describe three cases wherein gastric black dots appeared after the eradication of Helicobacter pylori as observed by magnifying endoscopy. In case 1, a 65-year-old woman was diagnosed with H. pylori -related gastritis and underwent H. pylori eradication. After 1 year, gastric black dots were observed by esophagogastroduodenal endoscopy (EGD) and dilation of the gastric crypts was noted on magnifying endoscopy. In case 2, a 63-year-old woman was diagnosed with H. pylori -related gastritis and underwent H. pylori eradication. After 1 year, gastric black dots were observed by EGD and magnifying endoscopy revealed dilated gastric crypts. In case 3, a 63-year-old woman was diagnosed with H. pylori -related gastritis and underwent H. pylori eradication by her previous doctor. After 2 years, gastric black dots were noticed on EGD and magnifying endoscopy showed dilated gastric crypts.
