A man aged above 70 years old with a medical history of ulcerative colitis presented with unintentional weight loss. A pancreatic mass associated with pancreatic duct dilatation was detected on imaging procedures. Initial investigations including fine needle aspiration and cytology examination were inconclusive. A diagnosis of intraductal tubulopapillary neoplasm (ITPN) was made with histopathology and immunohistochemistry examination on a surgically resected specimen. Two years after surgery, the patient remained well with no radiological evidence of recurrence.ITPN is a rare pancreatic duct tumour with limited case reports in medical literature. Risk factors are not well established. We report the first case of ITPN occurring in a patient with ulcerative colitis. A typical presentation of this rare tumour is reported to encourage clinicians to consider ITPN in the differential diagnoses of a pancreatic mass.
