A 50-year-old man, with a three-year history of diarrhea after eating, runny nose, and cough, consulted another hospital and was diagnosed with chronic sinusitis. At the time, chest computed tomography incidentally showed an anterior mediastinal tumor and bilateral centrilobular nodular opacities. Consequently, he was referred to our hospital. We suspected immunodeficiency because he had some persistent infectious symptoms. Laboratory test results indicated hypogammaglobulinemia. We performed thymothymectomy, and pathological examination revealed that the tumor was a type AB thymoma; he was finally diagnosed with Good syndrome. We aimed to prevent perioperative infectious complications by administering intravenous immunoglobulin before surgery. Fortunately, he had an uneventful postoperative course. He received intravenous immunoglobulin every four weeks; one year post-surgery, all of the patient's symptoms showed improvement. Good syndrome has been reported to be associated with a poor prognosis and no established treatment strategies are currently available. Therefore, we think that this case report is valuable as it outlines the clinical course of this condition.
