Helicobacter pylori-negative gastric ulcerations associated with celiac disease at first presentation.

Ulcers of the small bowel have repeatedly been described as a late complication of celiac disease and they are considered a signum mali ominis. We report a case of a 53-year-old woman presenting with diarrhea, epigastric pain and abdominal distensions for a period of few weeks. At upper GI endoscopy, biopsies were taken showing complete atrophy of the villi and colonization of the small bowel mucosa. Additionally, uncommon multilocular peptic ulcers were seen in the gastric antrum. These ulcers proved to be Helicobacter pylori-negative with no evidence of Zollinger-Ellison syndrome. Biopsies of gastric ulcers showed signs of a lymphocytic gastritis with an extensive infiltration of the lamina propria by almost exclusively CD3- and CD45R0-positive T-lymphocytes. Intraepithelial T-lymphocytes were found to be increased in the antral as well as the corpus mucosa. Typing the patient for human leukocyte antigens showed a DQA1*0501 and DQB1*0201 phenotype. According to the present report, gastric peptic ulcers seem to be another phenomenon associated with celiac disease. In the case presented here, ulcers were diagnosed together with celiac disease already at first presentation of the patient.
