TL;DR: This statement proposes a terminology scheme for the diagnosis of IgG4-related disease that is based primarily on the morphological appearance on biopsy, and advocates the use of strict criteria for accepting newly proposed entities or sites as components of the IgG 4- related disease spectrum.

TL;DR: The comprehensive diagnostic criteria for IgG4-RD are practically useful for general physicians and nonspecialists and have increased the sensitivity of diagnosis to 100% for Igg4-related MD, KD, and AIP.

TL;DR: It is suggested that AIP is not simply pancreatitis but that it is a pancreatic lesion involved in IgG4-related systemic disease with extensive organ involvement, and a new clinicopathological entity is proposed.

TL;DR: The categorization of AIP into types 1 and 2 should be helpful for further clarification of the clinical features, pathogenesis, and natural history of these diseases.

TL;DR: The working group has revised the guidelines regarding prediction of invasive carcinoma and high-grade dysplasia, surveillance, and postoperative follow-up of IPMN and includes updated information and recommendations based on the current understanding.
