Thymoma with recurrent opportunistic infections-a case report.

Good's syndrome (GS) is a rare adult-onset thymoma associated with acquired combined B-cell and T-cell immunodeficiency. It has similarities with Common variable immunodeficiency (CVID) in terms of hypogammaglobulinemia and significant risk of invasive bacterial and opportunistic infections. We still have a long way to go in understanding the pathogenesis of Good's syndrome. Here, we describe a case of a middle-aged female with thymoma and recurrent opportunistic infections. Clinico-laboratory evaluation led to a diagnosis of GS and she showed good response to intravenous immunoglobulin. Clinicians should be aware that thymoma can precede the onset of immunodeficiency.
