Mucosa-associated lymphoid tissue lymphoma of the duodenum forming multiple polypoid lesions: report of a case.
We report herein the case of a patient found to have mucosa-associated lymphoid tissue (MALT) lymphoma of the duodenum forming multiple polypoid lesions. Endoscopic examination revealed multiple small nodules with a yellow-white, rough surface in the duodenal bulb. Histopathological and immunological findings subsequently suggested low-grade B-cell MALT lymphoma. Cytologically, MALT lymphoma is similar to multiple lymphomatous polyposis (MLP); however, this case, which involved multiple polypoid lesions, was confirmed not to be MLP.
