a rare disease characterized by cartilaginous and bony growths in the trachea and bronchi that produce sessile polyps and plaques projecting into and partly obstructing the lumina.
tracheopathia osteoplasticaA segmental degenerative disorder of the tracheobronchial tree, which is characterised by multiple, variably sized submucosal cartilaginous and osseous nodules that cause upper respiratory tract narrowing. It is most common in elderly men, and may be associated with chronic inflammation or with trauma.
Nonspecific signs and symptoms; stridor, dyspnoea are common.
Scalloped nodular calcified opacities in the submucosa.
Tracheobronchomegaly and tracheomalacia, both of which demonstrate softening, flexibility or dilation of the trachea (in contrast with tracheopathia osteoplastica’s increased rigidity).
If focal, nothing; significant narrowing may require laser removal and dilation, followed by regular and meticulous tracheobronchial hygiene.
