Abstract: | MALT lymphoma often involves the stomach but much less commonly the small bowel. We present clinico-pathologic and radiologic features of a patient with recurrent gastrointestinal bleeding due to MALT lymphoma of the jejunum. Because of the small bowel location, the source of bleeding has been elusive, resulting in delayed diagnosis. The diagnosis was based on the small B cell morphology, demonstration of lympho-epithelial lesions, and immunophenotypic profile. |
