Autoimmune pancreatitis (AIP) is becoming increasingly recognized as a unique form of chronic pancreatitis. Its diagnosis, based on clinical and pathological parameters, is challenging. AIP is currently divided clinicopathologically into type 1 and type 2. Histological diagnostic criteria for type 1 and type 2 AIP have now been proposed by an international consensus study.
