Tracheobronchopathia Osteochondroplastica (TPO) on Bronchoscopy Tracheobronchopathia osteochondroplastica (TBPOCP) is an uncommon benign condition affecting the lumen of the tracheobronchial tree and characterized by abnormal chondrification and ossification of cartilages, sparing the posterior wall. TBPOCP is also referred by its synonyms tracheopathia chondroosteoplastica and tracheopathia osteoplastica. TBPOCP was first described in 1857 as ossific deposits in the larynx, trachea and bronchi by Wilks and colleagues. Accumulation of calcium phosphate in the submucosa of the large airways, and benign proliferation of bone and cartilage lead to the narrowing of the airways. TBPOCP is more frequent than it has been reported, as it can be asymptomatic or present with non‐specific respiratory symptoms. The common presenting symptoms of TBPOCP are chronic cough and wheezing, which often lead to the misdiagnosis of asthma. The aim of this review is to discuss clinical features, diagnostic approaches and current treatment recommendations for the patients with TBPOCP based on the literature. @pneumodoctor #Tracheobronchopathia #Osteochondroplastica #TPO #Bronchoscopy #clinical #video #pulmonary #TBPOCP
