Abstract:
A 72-year-old man with a lung tumor admitted to our hospital for surgical treatment. Computed tomography (CT) revealed a mass in the right middle lobe extending to the truncus intermedius and the left main bronchus. The enucleation of the tumor in the left main bronchus was performed with a bronchoscope followed by right middle and lower lobectomy. From the bronchial stump, the residual tumor was observed in the bronchus and was able to be pulled out since there was no invasion of the tumor into the bronchial wall. Pathological diagnosis was pulmonary carcinosarcoma.
