Utility of pVHL, maspin, IMP3, S100P and Ki67 in the distinction of autoimmune pancreatitis from pancreatic ductal adenocarcinoma

Morphology plays an important role in the distinction of autoimmune pancreatitis (AIP) from pancreatic ductal adenocarcinoma (PDAC). However, we aimed to determine the utility of immunohistochemical tumor markers to contribute in the distinction of these entities. In surgical specimens with AIP (n = 20), PDAC (n = 20) and normal pancreas (n = 20), the expression of pVHL, maspin, IMP3, S100P and Ki67 was examined. We evaluated intralobular...
