A case of good syndrome with pulmonary lesions similar to diffuse panbronchiolitis.
ABSTRACT We herein present a case of Good syndrome complicated by diffuse pulmonary lesions similar to diffuse panbronchiolitis (DPB). A 45-year-old Japanese man was referred to our department due to recurrent lower respiratory tract infections that had started and ameliorated nine months after thymectomy for pure red cell aplasia and myasthenia gravis. Diffuse centrilobular opacities on chest computed tomography and positivity for HLA-B54 were consistent with DPB. Additionally, hypogammaglobulinemia and a marked decrease of B-lymphocytes were observed, and therefore Good syndrome was considered. Combination therapy with azithromycin and clarithromycin alleviated the patient's respiratory symptoms and reduced the exacerbation of chronic bronchitis.
