Pancreatic vipoma is an unusual endocrine tumour, with only 5 cases reported in our country. We report a new case in a 41 year-old-male; the diagnosis was made on the basis of increased plasma levels of vasoactive intestinal peptide (VIP) and positive immunohistochemistry for VIP in the tumour. The peculiarities of this case were a strong steatorrhea which was managed with oral pancreatic enzymes and the findings of peritoneal carcinomatosis at the time of diagnosis.
