Malignant tumors can compress or invade the trachea or bronchi leading to varying degrees of airway narrowing. Lung cancer is the most frequent cause of airway occlusion of neoplastic origin1 and also the leading cause of death among all the malignancies in the world.2 However, distant metastatic tu

Primary tracheobronchial amyloidosis (TBA) is a rare disease characterized by extracellular focal or diffuse submucosal deposits of amyloid proteins. Various types of endobronchial lesions have been described in TBA when bronchoscopy is performed using white light. Narrow-band imaging bronchoscopy has been mainly employed for detecting preneoplastic and neoplastic endobronchial lesions as it provides more detailed images of the microvasculature reflective of an altered angiogenesis process. Here, we describe bronchoscopic findings with white light and narrow-band imaging in 2 patients presenting with central airway obstructive disease later confirmed as having primary TBA.

We present the case of a 33-year-old woman who was being treated for bronchial asthma for 4 years. A tracheal tumor was evident on a computed tomography of the thorax and removed with argon plasma coagulation. It was diagnosed as pleomorphic adenoma of the trachea. It is a rare tracheal tumor without definite treatment guidelines. Our endoscopic approach to this rare lesion is discussed.

Massive hemoptysis is a life-threatening event that requires emergency treatment. The aim of this study was to assess the effects of bronchial artery embolization on survival in cases of massive hemoptysis. This prospective study included 24 consecutive patients with massive hemoptysis who
