右B1＋3 転位気管支を伴う右上葉転移性肺腫瘍に対し右上葉切除術を施行した1 例

We experienced a resected case of metastatic lung tumor with a right displaced segmental bronchus （B1＋3）. The patient was an 82-year-old woman who had a history of surgery for transverse colon cancer. A chest computed tomography （CT） scan revealed a nodular shadow with an irregular margin（ 3.1 cm in diameter） in the right upper lobe, which was suspected of a primary lung cancer. Chest CT and bronchoscopy revealed B1＋3 displaced segmental bronchus. Thoracoscope-assisted right upper lobectomy was performed for diagnostic and therapeutic purposes. The pathological diagnosis was a metastatic lung tumor from the transverse colon cancer.
