Recurrent pneumonia post-thymectomy as a manifestation of Good syndrome

A 78-year-old woman presented with right lobar pneumonia. Six months before, the patient had undergone surgery due to a large mass that was found to be spindle cell thymoma. During the past 6 months, the patient had been admitted to the hospital several times with recurrent pneumonia in both lungs; this was treated successfully with antibiotics. Laboratory examinations revealed lymphopenia, eosinopenia, hypogammaglobulinemia, and a low count of CD4 T cells and an inverted CD4:CD8 T cell ratio, both on peripheral blood and bone marrow. History and laboratory findings were compatible with the diagnosis of the rare Good syndrome. This syndrome is discussed here.
