We present the case of a young patient with leiomysarcoma of the lung that was at first diagnosed as a hydatid cyst. Pathological tissue analysis was needed for firm diagnosis. This rare tumor, of which fewer than 100 cases have been reported worldwide in the literature, needs to be considered as a differential diagnosis when lung cancer is suspected, given that leiomysarcoma has a better prognosis. Treatment is mainly surgical.

Seven cases of endobronchial hamartoma are presented. Preoperative fiberoptic bronchoscopic biopsy provided the histologic diagnosis in two cases, but was inconclusive in the others. The tumor was removed by endoscopic resection (2 cases), local resection via a bronchotomy (1), lobectomy (2) or pneumonectomy (1). These six patients are alive and well 2-5 years postoperatively. The seventh patient refused treatment.
Two cases of patients suffering from a cystic lymphangioma of the mediastinum are presented. The literature is reviewed and the surgical and pathological findings are commented.
Blind pleural needle biopsy and diagnostic thoracoscopy are procedures sometimes used in the work-up of a patient with pleural effusion of unknown origin. We reviewed 203 diagnostic thoracoscopies in patients with malignant pleural effusion to show the different location of pleural metastasis, some out of the reach of blind needle biopsy. Based on these data, we find diagnostic thoracoscopy a superior procedure because of its higher reliability, faster diagnostic results, slight or no complications, and the possibility of carrying out pleurodesis in the same examination.
The authors report a series of 20 patients with single (8) or multiple (12) bullae. In most cases, exeresis of these bullae favorably affected functional signs. Standard spirometry (FEV1, VC) was improved significantly in long-term studies.
A series of 300 pulmonary resections in patients with lung carcinoma is presented. Total survival rate of the series since the operation, including surgical mortality, was 33% at 3 years and 24% at 5 years. The survival rate and surgical criteria were correlated, having better results when standard surgery was performed. The authors emphasize that the surgical figures of the series are of great value as the surgical indications were large and nonselective, with 85% of resectability in the thoracotomies.
