Intraductal papillary mucinous neoplasm (IPMN) is a rare pancreatic neoplasm. The presentation varies from recurrent pancreatitis, steatorrhea and weight loss to incidental findings during imaging studies. The recognition of IPMN is crucial in deciding for prompt surgical intervention, which is the best treatment modality for this precancerous condition. Here, we report a case of 55-year-old man with massive upper gastro intestinal bleeding arising from a huge fungating duodenal mass. In view of massive bleeding, a decision for emergency Whipple's pancreaticoduodenectomy was made. Final histological diagnosis confirmed as IPMN. To the best of our knowledge, this is the first case of IPMN presented with a huge fungating duodenal mass causing massive UGIB requiring surgical intervention.
