Tracheobronchopathia osteochondroplastica—case report and literature review.

Tracheobronchopathia osteochondroplastica (TBO) is a rare disease of unknown etiology characterised by a formation of multiple, cartilaginous and osteocartilaginous submucosal nodules in the trachea and major bronchi. The course of the disease is usually benign but the narrowing of the respiratory tract can lead to chronic non-specific clinical symptoms. We present a case of a 50-year old man with chronic exertional dyspnoea and stenosis of the trachea visible in imaging tests, in whom the symptoms were caused by TBO.
