Bronchiolo-alveolar cell carcinoma was diagnosed in a 69 year-old man who complained of fever and abundant sputum. Lesions were found in the right middle and lower lobe. The preoperative laboratory data revealed marked hypoxia (PaO2 51.0 Torr) and hypoventilation (%VC 51%). As total resection of the affected lobes was not desirable because of low lung function, middle lobe resection was performed. The postoperative lung function tests improved strikingly (PaO2 82.6 Torr, %VC 61%) Subsequently, lower lobe resection was performed. The results of lung function tests after the second operation were as follows: PaO2 82.1 Torr, %VC 53%. Hypoxia is one of the main manifestations of bronchiolo-alveolar cell carcinoma and the resection of the lesion can improve it. Hypoxia is caused by arterio-venous shunt at the bronchiolo-alveolar cell carcinoma lesion.
