RESUMEN
The retrospective study of 955 coin lesions of the lung showed 49% to be malignant. The proportion of malignant lesions increased with age. In patients older than 60 years of age, 65% of the lesions were malignant; in this group, bronchogenic carcinoma was the most frequent lesion. The delay prior to resection was especially pronounced in both younger patients and in patients with smaller lesions.

Pre-operative staging was carried out in 52 out of 112 patients suspected of having bronchial carcinomas, using computed tomography and conventional radiology. CT was superior in demonstrating tumour infiltration of the mediastinum, of the thoracic wall and of metastases in mediastinal lymph nodes. Conventional radiology was better for demonstrating intrabronchial tumour and metastases of bronchopulmonary lymph nodes. By extending CT to the upper abdomen, it was possible to show metastases in 18% of patients.
