Tracheobronchopathia Osteochondroplastica [case report]

ABSTRACT

Tracheobronchopathia Osteochondroplastica [TO] or Tracheopathia Osteoplastica is a rare disorder of large airways with unknown etiology. The diagnosis is usually made on bronchoscopy and confirmed on histology. Generally it is benign and asymptomatic but it may lead to serious complication like airway obstruction requiring surgical treatment. We describe two cases of TO with characteristic bronchoscopic and histological findings. The first one had squamous cell carcinoma of the lung, and the second one had chronic rheumatoid arthritis associated with interstitial fibrosis
