[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.

[Choriocarcinoma of the lung].

Primary choriocarcinoma of the lung is an extremely rare condition with a fatal outcome in most patients. We report the case of a 31-year-old woman with cough, chest pain, and hemoptysis, whose chest radiograph displayed nodules in the right upper lobe. After study and an unsuccessful attempt at histological characterization of the lesions, exploratory surgery was indicated.
