Minimal Lung Cancer with Extensive Chest Wall Invasion: Report of Two Cases

We describe rare 2 cases of minimal lung cancer with marked progression to the chest wall. The radiological findings revealed a chest wall tumor. Both cases underwent lobectomy concomitant with chest wall resection. Pathological study showed that well-differentiated carcinoma was minimal inside the visceral pleural and poorly differentiated tumor cells broke down the pleura and extended into the chest wall. Both cases died of recurrent cancer within 1 year after surgery.
