Abstract
A 49-year-old man presented with bloody sputum starting in June 1984. Chest X-ray examinations revealed giant bullae in bilateral upper lung fields with a small tumorous shadow in one of them on the left side. Sputum and brushing cytology were negative for malignant cells. Chest X-ray film taken six months later showed enlargement of the shadow, which was most suggestive of neoplasm. Left upper lobectomy was carried out in December 1984. As a lung cancer developing in a bulla was found, the hilar and mediastinal lymph nodes were resected. The histological diagnosis was large cell carcinoma. The pathological staging was T1 N0 M0, stage Ia. The postoperative course was uneventful and the patient's condition is good at 16 months after operation.
