A case of somatostatinoma of the pancreas is reported. A 64-year-old man was admitted to the hospital because of the chief complaint of weight loss. The patient has clinical symptoms of diabetes mellitus and cholelithiasis. Examination by CT, US and angiography revealed a hypervascular tumor of the pancreatic head. As measurement of hormones in the peripheral blood revealed an increase in somatostatin, a preoperative diagnosis of somatostatinoma of the pancreas was made. The patient underwent pancreaticoduodenectomy, which revealed a solid tumor of the pancreatic head and gall stones in the bladder. Postoperative examination revealed a high concentration of tissue somatostatinoma and immunohistochemically positive tumor cells. He was discharged after the operation and is well without recurrence.
