위부분절제술 후에 발생한 MALT 림프종 1예

Abstract

Gastrectomy is known to be a risk factor for adenocarcinoma in remnant stomach. It is suggested that reflux of bile juice or duodenal secretion to remnant stomach induces atrophic gastritis, intestinal metaplasia, and gastric adenocarcinoma. Malignant lymphoma in remnant stomach after gastrectomy is very rare. Only about thirty cases are reported in the world, and there is no case report in Korea. Gastric MALT (mucosa-associated lymphoid tissue) lymphoma is associated with Helicobacter pylori infection but the mechanism of lymphoma development in remnant stomach is still unknown. We report a case of low grade gastric MALT lymphoma of gastric stump after 10 years from partial gastrectomy.
