Good's syndrome (GS) or thymoma-associated immunodeficiency is a rare clinical syndrome with poor prognosis. The varied and unspecified clinical manifestations of GS commonly lead to a missed or delayed diagnosis. Thus, misdiagnosis and missed diagnosis are common. The present case study reports on a patient who suffered from a relapsed bloodstream infection caused by Alcaligenes sp. 6 months after thymectomy. The patient was finally diagnosed with GS after analyzing the clinical features and detecting T-lymphocyte subsets in the peripheral blood and humoral immune function. The patient's condition improved after anti-infection treatment and supplementation with intravenous immunoglobulin. Furthermore, no infection was observed during the 1-year follow-up.
Keywords: Alcaligenes sp; Good's syndrome; hypogammaglobulinemia; thymoma.
