[A case of thymoma associated with hypogammaglobulinemia].

In this paper, we report a case of thymoma associated with hypogammaglobulinemia, a relatively rare disorder. The case involved a 79-year-old man, who was told, following the diagnosis of an upper respiratory tract infection, that he had a tumor shadow in the anterior mediastinum. A preoperative examination revealed hypogammaglobulinemia. An extended thymectomy was performed. The tumor that was removed was found to be a noninvasive spindle cell thymoma. After three years of postoperative treatment, no tumor recurrence was observed. The hypogammaglobulinemia, however, did not improve, and the subject suffered from repeated occurrences of pneumonia.
