Abstract
We report a case of non-functional pancreatic endocrine tumor growing into the main pancreatic duct (MPD) which is rare.
A 46-year-old woman was admitted to our hospital because of epigastralgia. On admission, an egg-sized tumor was palpable at the epigastrium and hematological studies showed that the values of tumor markers and gastrointestinal hormones were in normal ranges. Abdominal echography, CT, MRI, angiography, PET and ERCP revealed two hypervascular lesions which were adjacent each other but one in the pancreatic parenchyma and the other in the MPD. We performed pancreaticoduodenectomy. Because the resected specimen showed that the tumor was growing into the MPD from the parenchyma and a histopathological study proved each and every lesion to be the same endocrine tumor. Consequently the final diagnosis was non-functional pancreatic endocrine tumor growing into the MPD.
