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.

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
