Differentiation of pancreatic lymphoma from ductal adenocarcinoma is crucial because of different therapeutic regimens and outcomes. Moreover, lymphomas coexistent with adenocarcinomas are rare. We reported a case o f a 77-year-old male suffering from intermittent epigastric pain, diarrhea, and loss of body weight. Ultrasonography and computed tomography revealed a big pancreatic mass and another left atrial tumor. Panendoscopy showed a tumor at duodenal bulb and colonoscopy found a tumor at rectosigmoid area. Fine-needle aspiration cytology from the pancreatic mass and endoscopic biopsy from duodenal tumor revealed lymphoma of diffuse large B cell origin. Endoscopic biopsy of this colonic tumor showed adenocarcinoma. The patient refused further treatment. The differential diagnosis and management of the rare disease entity will be discussed.Adenocarcinoma; Colon; Lymphoma; Pancreas[SDGs]SDG3aged; article; aspiration biopsy; case report; colon carcinoma; colonoscopy; computer assisted tomography; diarrhea; duodenum tumor; echography; endoscopy; epigastric pain; human; human tissue; lymphoma; male; nuclear magnetic resonance imaging; pancreas adenocarcinoma; pancreas tumor; weight reductionjournal article2-s2.0-0030823686
