A 62-yr-old man presented with a 5-yr history of intermittent abdominal distention and pain. These symptoms persisted for several months and subsided without treatment. A diagnosis of suspected small bowel lymphoma was made based on plain radiograph and computerized tomogram findings, and he was referred to our institution for further evaluation. Segmental resection of the small intestine was performed and the diagnosis of marginal zone B-cell lymphoma associated with amyloidosis was made. This is the first case of marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) in the small intestine associated with amyloidosis in Korea.
