[Obstruction of the superior vena cava and right subclavian vein: a propos of 2 unusual cases].

Two uncommon cases of vein obstruction are presented. In the first case a syndrome of superior, caval vein obstruction was caused by idiopathic fibrous mediastinitis involving the vein wall, and creating a tumefaction in the lumen of the vein simulating the existence of a benign tumor (fibroma) of the wall. This tumefaction was removed by endvenectomy, and the venotomy was repaired by a pericardial patch. In the second case the obstruction of the right subclavian vein was caused by a stenosed valve without signs of inflammation nor consecutive thrombosis. Until the present day no other similar case of a stenosed valve in the right subclavian vein has been reported.

Bronchioloalveolar carcinoma: long-term survival of 23 resected patients.

We studied 23 patients, who underwent resection for bronchioloalveolar carcinoma between 1975 and 1992. The predictive value of the radiologic features, TNM staging, histopathologic type and extent of resection were examined. There were 20 men and 3 women (13%) with a mean age of 58 years (32-72y). Of all patients, 18 (78.3%) were asymptomatic. At chest X-ray, 14 (61%) revealed a solitary nodule, 6 an infiltrative or pneumonic mass, one a cystic lesion, and two multinodular lesions. The actuarial five-year survival was 46 +/- 23%. When a lobectomy was performed for bronchioloalveolar carcinoma, survival was better than when a pneumonectomy was performed. None of the seven patients who underwent a pneumonectomy survived 5 years. The actuarial 5-year survival of the 16 lobectomies was 70 +/- 25%. There was no statistical difference in survival between the histopathologic types.

Intrathoracic ganglioneuroma: case report.

Ganglioneuromas are rare, benign neoplasms, arising from the sympathetic nervous system. The posterior mediastinum is the most common location of this neurogenic tumour. We present this case because of the problem of its diagnosis. Our patient had in fact been under observation for about twenty years. The size of the tumour caused a restriction of the pulmonary function.
