Abstract
- Pseudolymphoma or lymphoid hyperplasia is a rare clinicopathologic disease which occurs in a variety of sites including the skin, orbit, salivary glands, gastrointestinal tract, lung, and other organs. Lymphoid hyperplasia of the gastrointestinal tract can be categorized into four clinicopathologic groups: focal lymphoid hyperplasia of the stomach, focal lymphoid hyperplasia of the small intestine, focal lymphoid hyperplasia of the rectum, and nodular lymphoid hyperplasia of the gastrointestinal tract. We experienced two cases of nodular lymphoid hyperplasia of the small intestine with hypogammaglobulinemia (IgA deficiency) and without hypogammaglobulinemia presented with epigastric discomfort. Esophagogastroduodenoscopy and small bowel series showed 0.2~.5 cm sized small, numerous Yamada-I or Yamada-II polypoid lesions from the duodenal bulb to the terminal ileum in two cases. Histologic finding of the duodenal bulb showed small round mature lymphocyte infiltration and reactive follicle with germinal center in two cases. We report two cases with a brief reviews of literature.
