The patient developed a cough in October 2010 and visited our division. He had a high serum concentration of immunoglobulin (Ig) G4 and his chest computed tomography showed airway stenosis without bilateral hilar lymphadenopathy (BHL). The bronchial biopsy specimens revealed lymphoplasmacytic infiltrations with IgG4-positive/IgG-positive plasma cells of more than 50%. Thus, we diagnosed the airway lesion with IgG4-related airway involvement. This is the first report of a patient with IgG4-related airway involvement without BHL., Article, INTERNAL MEDICINE. 50(24):3023-3026 (2011)}, pages = {3023--3026}, title = {IgG4-Related Airway Involvement Which Developed in a Patient Receiving Corticosteroid Therapy for Autoimmune Pancreatitis}, volume = {50}, year = {2011} }
