Abstract:
Tracheobronchopathia osteochondroplastica (TBOC) is an unusual respiratory disorder characterized by cartilaginous or bony mucosal nodules in the tracheobronchial tree. It mainly affects men over 50 years old and clinical manifestations are observed when obstructive or infectious complications occur. We report a case of tracheopathia osteoplastica of the upper third of the trachea in a young 35-year-old mal, fortuitously discovered while exploring a biliptysis caused by a broken hydatic cyst of the liver. TBOC can be associated with various metabolic, inflammatory and neoplastic disorders, but its pathogenesis remains unknown. A metaplastic origin is actually the main hypothesis proposed.

CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
