Objective: IgG4 -related lung disease is one of the manifestations of IgG4-related systemic disease. Obliterative vasculitis is considered an organ specific feature of IgG4-related disease in the lung. We report a case of a 78-year-old man with multifocal subpleural consolidations in both lungs. Histologic examination revealed IgG4-related lung disease with obliterative lymphoplasmacytic vasculitis.
