Autoimmune Pancreatitis Type II: First Report from India.

Autoimmune Pancreatitis (AIP) presents in two forms - Type I or lymphoplasmacytic sclerosing pancreatitis and Type II or idiopathic ducto-centric pancreatitis (IDCP). AIP II is rare in south Asia and, especially so, in India. Most patients have either Idiopathic Chronic Pancreatitis (ICP) or alcohol related chronic pancreatitis. AIP Type I has been described in India. We herein report a patient who had features of ICP on imaging, for whom surgery was performed to relieve chronic pancreatic pain. However, the pathologic features revealed AIP Type II or IDCP.
