Multiple primary cancer is a disease of more than two cancers occurring in an individual independently. We experienced a case of triple primary cancer, that is lung cancer, malignant thymoma and bladder cancer which has not been reported in
Korea.
The
patient was a 60 year old man with dyspnea and chest discomfort. He was first diagnosed bladder cancer and received Bricker's operation 3 months ago. At that time the chest roentgenography and computerized tomographic scan revealed as a
preaortic,
retrosternal mediastinal mass and a lung mass at the posterior portion of the left lower lobe. On operation, there was an identifiable lung mass in the left lobe and a thymoma already invaded the surrounding structures. So, left lower lobectomy
and
thymectomy were performed simultaneously. He received one cycle of postoperative chemotherapy, but refused further management and self-discharged. He died, about one year later.
