Abstract
Thymoma with Immunodeficiency (Good's Syndrome, GS) is a rare association between thymoma and immunodeficiency, first described over 60 years ago. Patients with GS typically present with thymomas, reduced or absent B cells in the peripheral blood, hypogammaglobulinemia, and defects in cell-mediated immunity. We report the case of a 67-year-old woman diagnosed with GS following the development of a progressive, severe, refractory pulmonary infection and diffuse panbronchiolitis (DPB). She also had diabetes, characterized by anti-glutamic acid decarboxylase antibody positivity, leading to a diagnosis of latent autoimmune diabetes in adults (LADA). A thorough review of existing literature revealed that GS is often confirmed after multiple episodes of opportunistic infections or autoimmune diseases post-thymoma surgery. Due to their immunodeficiency, GS patients frequently suffer from recurrent infections over extended periods, and some succumb to severe infections. Regular immunoglobulin infusions may be effective in treating GS.
