Diagnosis and treatment of autoimmune pancreatitis： analysis of six cases

Autoimmune pancreatitis （AIP） is a rare and special type of chronic pancreatitis, which was earlier referredto as lymphoplasmacytic sclerosing pancreatitis （LPSP）, idiopathic duct destructive pancreatitis, or granulocyte epithelial lesion-positive pancreatitis. The concept of AIP was not coined by Yoshida until 1995.1 Although AIP was initially reported in Japan, USA and Europe, AIP cases have increased rapidly in China in the last few years.
