Successful Resection of a Giant Pulmonary Colloid Adenocarcinoma via Median Sternotomy

Abstract

We report on a giant pulmonary colloid adenocarcinoma successfully resected using a median sternotomy approach. A 69-year-old woman visited our hospital owing to a giant mass detected on chest radiography. A giant cystic mass measuring 115 × 90 mm was detected in the right upper lung using computed tomography. We suspected mucinous adenocarcinoma and performed right upper lobectomy and mediastinal lymph node dissection with median sternotomy. The surgical field of view for the tumor and superior vena cava was satisfactory, and compression but not invasion of the superior vena cava and chest wall by the tumor was observed. The tumor was pathologically diagnosed as a colloid adenocarcinoma of stage IIIA with pT4N0M0. The postoperative course was uneventful, with no signs of recurrence at one and a half years after operation. Thus, this case demonstrates that for giant lung tumor surgery, median sternotomy is useful and safe for improving the surgical field of view.
