ntroduction: Chronic granulomatous disease (CGD) is a rare immunodeficiency disorder characterized by recurrent infections with catalase positive bacteria. The cause is some defect in bactericidal activity of neutrophils and fungal organisms.
Case Report: In this study a 23 years old man with history of recurrent pulmonary and lymph node infection has presented. He was misdiagnosed for TB three times and received anti- TB treatment. Finally the Chronic Granulomatous was confirmed. Conclusion: This case study demonstrated that CGD should be considered in adults with unexplained recurrent infections to prevent wrong treatment due to misdiagnosis and to reduce the disease severity by prophylactic treatments.
