[A Good syndrome associated with pure red cell aplasia].

A 78-year-old woman was admitted because of persistent cough, fever and sputum for one week. She had been treated with radiation therapy for inoperable thymoma complicated by severe heart failure and had been suffering from recurrent pneumonia and otitis media since then. A chest radiograph on admission showed an anterior mediastinal mass shadow and infiltrates in the bilateral lower lung fields. Serum gamma globulin was decreased and erythroid cells in the bone marrow were markedly decreased. Thymoma with hypogammaglobulinemia is called Good syndrome. We reported this very rare case of Good syndrome. After improving the infection, cyclosporine A was administered for PRCA and hypo-gamma globulinemia, but we discontinued this due to liver dysfunction. We have been currently continuing her treatment with red blood cell transfusion and immunoglobulin supplement only.
