Thymoma-associated immunodeficiency: a diagnostic challenge for the clinician

Abstract

Good’s syndrome or thymoma-associated immunodeficiency is a rare clinical entity that is often presumed to be common variable immunodeficiency, due to lack of awareness and recognition of this syndrome. This syndrome more often goes unrecognized if a thymoma is not detected. An appropriate immunological work-up that aids timely diagnosis and adequate therapy with antimicrobials and intravenous immunoglobulins are mandatory to prevent the long-term complications and mortality associated with this syndrome. We present the clinical and immunological profile of a young man with Good’s syndrome that was initially presumed to be common variable immunodeficiency.
