We have described the first case, to our knowledge, in which recurrent respiratory tract infections were the primary manifestation of thymoma with immunodeficiency (Good's syndrome) associated with cobalamin malabsorption and immunoglobulin M-kappa (IgM-kappa) M component. The intrinsic factor receptor activity was dramatically decreased in a mucosal homogenate prepared from ileal biopsies. This decreased activity could be the principal cause of the malabsorption of labelled cobalamin which was observed in the presence of intrinsic factor. However, it could be the consequence of the cobalamin deficiency, as it is known that a cobalamin deficiency can affect the assimilation of cobalamin, even in presence of exogenous intrinsic factor.

We report the case of a patient with severe diarrhea and malabsorption who was subsequently found to have hypogammaglobulinemia and thymoma (Good's syndrome). The mechanism by which hypogammaglobulinemia and/or thymoma causes diarrhea is unclear. It may be related to malabsorption caused by a mucosal lesion resembling villous atrophy, which may resolve with restoration of immunologic status. Diarrhea in some patients may respond to commercial gamma globulin injections, fresh frozen plasma, or cholestyramine therapy. The etiologic relationship between thymoma and acquired hypogammaglobulinemia remains unclear. Thymectomy is generally ineffective in improving immunologic deficiencies and coexisting conditions in patients with acquired hypogammaglobulinemia. In our patient's case, severe diarrhea resolved after resection of the thymoma.

Good's syndrome is an infrequent disorder associated with humoral immunodeficiency and thymoma. Patients usually present severe or chronic infections. The most frequent are sinopulmonary infections sometimes associated with bronchiectasias. Another complication is chronic diarrhea, frequently associated with malabsorption, which can be due to a mucosal lesion, infection with gastrointestinal pathogens, or bacterial overgrowth. We describe a patient with Good's syndrome and chronic diarrhea due to bacterial overgrowth.
