| Abstract |
|
Autoimmune pancreatitis (AIP) has been increasingly recognized in recent years, and most cases are diagnosed without surgery. However, focal-type mass-forming AIP is difficult to differentiate from pancreatic cancer without surgical resection. A 61-year-old male patient with a clinical impression of pancreatic cancer underwent surgery. A postoperative pathologic examination showed locally dense lymphoplasma cell infiltration and numerous lymphoid follicles with fibrosis and a low-grade intraductal papillary mucinous neoplasm (IPMN). Here, we report the first case of localized mass-forming AIP combined with a low-grade IPMN, which mimicked pancreatic cancer, in Korea. (Korean J Med 2014;86:466-471) |
