Ectopic pancreatic-type malignancy presenting in a Meckel's diverticulum: A case report and review of the literature

Abstract

Background: Neoplasms arising from Meckel's diverticulae reported in the literature are mainly carcinoid tumours, gastrointestinal stromal tumours, and gastric or intestinal adenocarcinomas. Case presentation: We describe a 50-year-old man who presented with rectal bleeding and anaemia, later found to be caused by a pancreatic adenocarcinoma arising from ectopic pancreatic tissue in a Meckel's diverticulum. The tumour was unfortunately highly aggressive, and the patient passed away within 5 months of symptom onset. Conclusion: We believe this is the first case of pancreatic adenocarcinoma in a Meckel's diverticulum to be reported in the literature. The diagnosis of Meckel's should be considered in patients with acute gastrointestinal complaints; when found incidentally at laparotomy, it should be carefully examined for any gross abnormality and resection should be considered. © 2009 Koh et al; licensee BioMed Central Ltd.
