A CASE REPORT OF TUMOR FORMING PANCREATITIS

Abstract

A 72-year-old man was admitted to our hospital because of upper abdominal pain and weight loss. Abdominal ultrasonography revealed a 4×4 cm hypoechoic tumor in the head of pancreas. Selective celiac angiography showed encasement of the posterior superior pancreatoduodenal artery. Pancreatoduodenectomy was carried out under a diagnosis of pancreatic cancer. The resected specimen showed that the tumor was stony-hard and 4 cm in diameter. Histological examination denied pancreatic cancer and demonstrated severe chronic pancreatitis. We report a case of so called “tumor forming pancreatitis” which is occasionally differentiate from pancreatic cancer.
