title: A case of solely lung-involved IgG4-related disease mimicking tuberculosis.
abstract: IgG4-related disease (IgG4-RD) is a chronic progressive autoimmune disease. Solely lung involved IgG4-RD is extremely rare. Herein, we reported a case of IgG4-related disease as mimicking tuberculosis. A 52-year-old male patient was admitted due to cough and hemoptysis for two months and fever for 1 month. The pre-admission diagnosis in another hospital was secondary pulmonary tuberculosis, but the quadruple anti-tuberculosis therapy was ineffective and the disease condition continued to deteriorate. The percutaneous lung biopsy was carried out after admission and the pathological diagnosis was IgG4-related disease. The patient's disease condition was improved following hormonal therapy.
