PRIMARY GASTRIC LYMPHOMA PRESENTING WITH VITAMIN-B-12 DEFICIENCY AND ACHLORHYDRIA

Gastric lymphoma is an uncommon condition, usually presenting with epi gastric pain and/or dyspepsia. There is now good evidence that infecti on with Helicobacter pylori (Hp) is etiologically important. We report here a case of primary gastric lymphoma presenting with vitamin B-12 deficiency anemia and achlorhydria in which there was evidence of prev ious, but not current, infection with Hp. Vitamin B-12 deficiency was proven to be due to intrinsic factor deficiency. To our knowledge, thi s condition has not previously been reported.
