Mohamed Boudjelal, Danuta E. Mosskowsaka and Stuart Farrow

We present a case of a 61 year old man admitted for epigastric pain and fatigue. Computed tomography and endoscopy revealed the presence of a gastric mass and multiple polyps in the duodenum. The patient also had widespread lymphadenopathy, ascites and pleural effusion. Genetic and immunohistochemical testing confirmed the diagnosis of disseminated mantle cell lymphoma. To the best of our knowledge, we are the first to describe a case of simultaneous gastric and duodenal mantle cell lymphoma.
