RAPID REOCCLUSION OF LEFT PRIMARY BRONCHUS BY FIBRINOMUCINOUS CAST INA CASE OF LARGE-CELL LUNG-CANCER

This report describes a case of large cell carcinoma of the lung in a patient whose left primary bronchus became completely occluded by a fi brinomucinous cast that recurred within 24 hours despite extensive lav age and removal of the cast via flexible bronchoscopy. The primary tum or involved the aortopulmonary window and was affixed to the pulmonary artery and the aorta, arising from the left upper lobe and extending to the left primary bronchus. The occurrence of a large fibrinous endo bronchial cast removed by flexible bronchoscopy forceps, such as we re port here, is extremely rare.
