6 cases of tracheobronchopathia osteochondroplastica are discussed. Diagnoses were established ante mortem. Endoscopic examination was performed in 3 patients because of hematic expectoration, in the other 3 cases the induction was given by chronic bronchorhea, slow-resolving pneumonia and suspected neoplasia, respectively. Calcification and cartilaginous areas were restricted to a small portio...

The chemical and physical properties of serpentine and amphibole asbestos are considered in the context of their interaction with tissue of the tracheobronchial tree and lungs. In vitro studies in cultures of several types are evaluated and work with the erythrocyte hemolysis system is reviewed. Although fibers of the two major mineral types differ substantially, it is likely they are modified ...

The ability of the lungs to clear deposited material is essential for maintenance of lung homeostasis. Acid aerosols have been shown to alter the efficiency of this process. This paper assesses the role of acid aerosol exposure concentration (C), exposure time (T), and relative acidity in producing changes in clearance from both the tracheobronchial tree and respiratory region of the lungs of r...

Human rhinoviruses (HRV) usually cause upper airway infections. However, viral replication in the tracheobronchial tree has been disclosed, although its clinical role is poorly known. We evaluated the prevalence of HRV in 159 bronchoalveolar lavages from 88 patients and describe a lung transplant recipient with a high HRV load in association with acute rejection. HRV was detected in 22/88 patie...

Aspiration of a foreign body into the tracheobronchial tree is rare in adults. In the majority of these cases there is an underlying condition such as mental retardation, depressed mental status, impairment in the swallowing reflex, neurological impairment, alcohol or sedative abuse, or complications from dental manipulations that contributed to the aspiration. These patients are commonly misdi...

Tooth aspiration in adults during endotracheal intubation is very rare. There are several risk factors for this rare event such as old age, loose teeth, difficult intubation etc. which predispose patients for tooth aspiration in tracheobronchial tree in emergent endotracheal intubation. Although extraction of aspirated tooth with flexible bronchoscopy is a difficult and complex intervention, it...

Stridor is predominantly an inspiratory sound that is associated with upper-airway obstruction. Stridor can be caused by a variety of benign and malignant conditions. In an adult with stridor and a history of endotracheal intubation, laryngotracheal stenosis must be considered in the differential diagnosis. Laryngotracheal stenosis is most commonly the consequence of instrumentation, primarily ...

Endobronchial tuberculosis is defined as a tuberculous infection of the tracheobronchial tree and has a prevalence of up to 50% in active pulmonary tuberculosis cases. The most common complication of endobronchial tuberculosis is bronchial stenosis; benign fistula formation by endobronchial tuberculosis is rare, especially inter-bronchial fistula formation. We reported a rare case of a 73-year-...

Cutaneous bronchogenic cysts are rare, and stem from developmental abnormalities of the tracheobronchial tree. The condition is often misdiagnosed clinically, with the correct diagnosis usually established by histopathologic examination. Published reports of bronchogenic or branchial anomalies are increasing, and the traditional defining characteristics of location and histopathology are provin...

An intra-abdominal bronchogenic cyst (BC) is a very rare congenital anomaly caused by abnormal budding of the developing tracheobronchial tree. Intra-abdominal BCs are reported as retroperitoneal masses in most cases, many of which are located on the left side of the midline, the perigastric area, the left adrenal gland, or the superior body of the pancreas. Intra-abdominal BCs are frequently m...
