[Pleural-origin malignant lymphoma in an elderly patient with chronic empyema and infection with the Epstein-Barr virus].

An artificial pneumothorax had been induced to treat pulmonary tuberculosis about 40 years previously. The year after she began to complain of lumbago, a tumor mass over the right anterior chest wall had grown rapidly.
