Background on the preparation of the diagnostic criteria
IgG4-related disease (IgG4-RD) [1] is a newly recognized systemic disease characterized by an elevated serum level of IgG4, infiltration of IgG4-positive plasma cells into affected lesions, and fibrosis. In 2011, comprehensive diagnostic criteria for IgG4-RD were proposed by the Study Group of Intractable Diseases from the Ministry of Health, Labor and Welfare, Japan (MHLW) [2], and these criteria have been gaining increasing acceptance.
The comprehensive diagnostic criteria [2] are highly
Nomenclature of respiratory tract lesions
At the International Symposium on IgG4-RD held in Boston in 2011, two separate names were adopted for the respiratory tract lesions of IgG4-related disease: ‘IgG4-related lung disease’ and ‘IgG4-related pleural disease’ [5]. However, since a subsequent report that respiratory tract lesions are typically interstitial lesions [6], the Ministry of Health group decided to refer to lesions of both the intrathoracic respiratory organs and auxiliary structures collectively as ‘IgG4-related respiratory
Summary
The diagnostic criteria of IgG4-RRD are outlined. We hope for further consideration and acceptance of the criteria.

It has been reported that the respiratory system could be a target of IgG4-related disease, and Matsui S et al. proposed acceptable diagnostic criteria for it [10,11]. On the basis of these criteria, the pathological findings of the first VATS in 2013 and other clinical manifestations met the criteria for definite diagnosis of IgG4-related lung disease.
