[Surgical treatment of pulmonary lesions in a single lung].

We performed surgery on 4 patients who had previously undergone left pneumonectomy and presented a second pulmonary lesion (3 lung cancers; 1 metastasis from colon cancer). Patients were aged between 52 and 79 years; 3 were men. Wedge resection was performed in 3 patients and segmentectomy in the other.
