Stage 1A Pancreatic Cancer Initially Manifesting as Clinical Acute Pancreatitis / 대한내과학회지

ABSTRACT

Pancreatic cancer has a poor prognosis due to the difficulty of early diagnosis. Observation is recommended for early diagnosis of pancreatic cancer in elderly patients with risk factors such as newly diagnosed diabetes and chronic pancreatitis. A 66-year-old male suffered from acute pancreatitis of uncertain etiology. Initial pancreatic imaging showed a main pancreatic duct stricture at the pancreas body/tail junction and minimal duct dilatation without a visible mass. Eight months later, however, pancreatic imaging revealed a pancreatic mass at the previous stricture site with progression of the upstream duct dilation. The patient underwent distal pancreatectomy, and a pathologic examination showed stage 1A pancreatic cancer with a predominantly intraductal spreading pattern. We report a case of stage 1A pancreatic cancer that initially manifested as acute obstructive pancreatitis, which enabled early diagnosis of pancreatic cancer.
