Good syndrome is a rare cause of combined B- and T-cell immunodeficiency that occurs in association with a thymoma The association between the presence of a thymoma and immunodeficiency was first recognised in 1954 by Dr Robert Good, who described a case of thymoma and hypogammaglobulinaemia in an adult Patients with Good’s syndrome usually present in the 4th or 5th decade of life The initial clinical features of Good’s syndrome are varied.The initial diagnosis may be prompted by the finding of an asymptomatic anterior mediastinal mass on chest x ray. Patients may complain of symptoms secondary to the thymoma itself such as cough, chest pain, dysphagia, dyspnoea, and hoarseness The most common cause of infection in this patient population is recurrent sinopulmonary infection secondary to encapsulated organisms This disorder should be treated by resection of the thymoma and immunoglobulin replacement to maintain adequate trough IgG values
