[Association of Good syndrome with pure red cell aplasia: report of one case].

The association between Good's syndrome (hypogammaglobulinemia and thymoma) with pure red aplasia is very uncommon. We report a 70-year-old male, who had a thymoma excised nine years before. Afterwards, he suffered frequent respiratory infections, which were attributed to a humoral immunodeficiency. Nine years later, he developed a pure red cell aplasia. He received prednisone and cyclosporine, resulting in a progressive rise of hemoglobin level, after one month of treatment. The patient died shortly thereafter due to infection, complicating a domestic accident.
