Thymoma with immunodeficiency (Good's syndrome) associated with myasthenia gravis and benign IgG gammopathy

Abstract

We treated a case of thymoma with immunodeficiency (Good's syndrome) associated with a rare combination of other parathymic syndromes including myasthenia gravis, benign IgG lambda M component, pernicious anemia, and diabetes. The characterization of the patient's immunologic capacity disclosed practically normal T-cell number and mitogenic responses but impaired lymphokine production as well as B-cell function.
