Mucosa-associated-lymphoid-tissue (MALT) lymphomas are the most common primary gastrointestinal lymphomas. The stomach is the most common site of involvement in the GI tract. However, MALT lymphoma of the duodenum is rare. The differential diagnosis in a refractory peptic ulcer are current smoking, NSAID use, hypersecretory conditions (gastrinoma and Zollinger-Ellison syndrome), neoplasms, infection (cytomegalovirus, syphilis, and tuberculosis), and Crohn's disease. Endoscopic findings of duodenal MALT lymphoma are classified as ulcerative, polypoid, and diffuse types. The ulcerative type is the most common type of duodenal MALT lymphoma. Here, we report a case of a 64-year-old male with a history of a refractory duodenal ulcer who was diagnosed with a duodenal MALT lymphoma by immunohistochemical staining.
