Gastric stump lymphoma is uncommon. We report a case of MALT lymphoma of the gastric stump occurring in a 65 year-old male. This patient had undergone subtotal gastrectomy for a gastric peptic ulcer at age 51. Histologic findings in the initial gastric specimen showed follicular gastritis with Helicobacter Pylori. This previous gastric surgery cured the ulceration but did not remove the Helicobacter Pylori infection that led to the development of gastric lymphoma.
