Abstract
A 38-year-old Peruvian woman visited our outpatient unit with the chief complaints of heartburn and epigastralgia. 14C urea breath test was Helicobacter pylori (H. pylori) positive. Esophagogastroduodenoscopy, capsule endoscopy and colonoscopy revealed small whitish nodules extending from the gastric antrum to the end of the ileum. Although all of the biopsy specimens from nodules revealed lymphoid follicles, immunohistological examinations showed that the nodules in the stomach were reactive lymphoid hyperplasia associated with nodular gastritis while the nodules in the bulb, descending duodenum, and the ileum were follicular lymphoma (FL). Our final diagnosis was that only the gastric nodules were reactive lesions, often called nodular gastritis associated with H. pylori infection, but that the other nodules were FL.
