Clinical diagnostic criteria of autoimmune pancreatitis: revised proposal.

The article discusses the proposed amendments for clinical diagnostic criteria of autoimmune pancreatitis (AIP) by the Research Committee of Intractable Diseases of the Pancreas. The extrapancreatic lesions that may be associated with AIP include biliary lesions, sialadenitis, retroperitoneal fibrosis, enlarged celiac and hilar lymph nodes, and chronic thyroiditis. Patients with AIP demonstrate infiltration of lymphocytes and plasma cells, and obliterative phlebitis.
