Good Syndrome Presenting With Pulmonary Abnormalities Four Years After Thymectomy

Area of Science:

• Immunology
• Oncology
• Pulmonology

Background:

• Good syndrome is a rare primary immunodeficiency characterized by thymoma, hypogammaglobulinemia, and B-cell depletion.
• Recurrent respiratory infections and unexplained pulmonary abnormalities can be presenting symptoms.

Purpose of the Study:

• To highlight Good syndrome as a potential diagnosis in patients with a history of thymoma presenting with recurrent respiratory infections and pulmonary abnormalities.
• To emphasize the importance of immunologic evaluation in diagnosing Good syndrome post-thymectomy.

Main Methods:

• Case report of a 72-year-old woman with a history of thymectomy presenting with recurrent respiratory infections.
• Diagnostic workup included chest CT, bronchoalveolar lavage, and comprehensive immunologic evaluation.
• Treatment involved corticosteroids, antibiotics, and subsequent intravenous immunoglobulin therapy.

Main Results:

• The patient was diagnosed with Good syndrome, exhibiting profound hypogammaglobulinemia and near absence of peripheral B cells.
• Treatment with intravenous immunoglobulin led to increased serum IgG levels and prevention of further respiratory infections.
• Pulmonary abnormalities and respiratory symptoms improved with treatment.

Conclusions:

• Good syndrome can present clinically years after thymectomy, even without thymoma recurrence.
• Prompt immunologic assessment and treatment are essential for managing Good syndrome and its complications.
• This case underscores the need to consider Good syndrome in the differential diagnosis of post-thymectomy patients with respiratory issues.
