Combined rigid and flexible endoscopic removal of a BB foreign body from a peripheral bronchus.

Aspirated foreign bodies (FB) in the peripheral tracheobronchial tree may present challenging management problems for the bronchoscopist. Critical to successful removal is maintaining airway control while minimizing endoscopy time. An innovative approach utilizing rigid and flexible bronchoscopy in removal of a distal impacted airway is presented. Difficulties encountered as well as advantages of this combined approach are discussed.

Social consequences of brain or liver relapse in small cell carcinoma of the bronchus.

The time spent in hospital when cerebral metastases occur as the first site of relapse in patients with small cell carcinoma of the lung (SCCL) has been analysed and compared to the consequences of relapse in the liver. In the course of a clinical trial with 370 patients, 50 patients relapsed initially in the brain and 20 in the liver. The 2 groups were comparable with respect to performance status at diagnosis and the amount of home support available. Patients who relapsed in the brain suffered a greater deterioration in performance status, and spent a greater proportion of their remaining life in hospital than did patients whose initial relapse was in the liver. This difference was most marked in patients who died soon after relapse. Radiotherapy (20 Gy in 5 fractions over one week or 30 Gy in 10 fractions over 2 weeks) and dexamethasone were not very effective treatments for brain relapse though subjective responses were common. The substantial morbidity and lengthy hospitalisation resulting from brain relapse compared with relapse at another site is a important factor to be considered in assessing whether prophylactic cranial irradiation should routinely be offered to patients with SCCL.

[Benign salivary gland-type tumors of the bronchus: expression of high molecular weight cytokeratins].

Primary lung tumors showing features of salivary gland-type neoplasms are extremely rare, and their immunohistochemical profile has been seldom studied. We report two cases of bronchial pleomorphic and mucous gland adenomas and study the expression of markers such as TTF-1 and high molecular weight keratins in these tumors. Both tumors were endobronchial. The pleomorphic adenoma also had a well-circumscribed parenchymal component, with a biphasic morphology composed of epithelial and myoepithelial cells in a background of myxoid and hyaline stroma. The mucous gland adenoma displayed papillary and dilated glandular structures. In both cases, epithelial cells showed strong and diffuse cytoplasmic staining with high molecular weight cytokeratins (cytokeratin 5/6 and keratin 903), and lacked TTF-1 expression. This immunoprofile provides useful clues for the histogenesis of pulmonary benign salivary gland-type adenomas and helps in distinguishing them from primary adenocarcinomas in small biopsy specimens.
