翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Tracheobronchopathia osteochondroplastica ： ウィキペディア英語版 Tracheobronchopathia osteochondroplastica Tracheobronchopathia osteochondroplastica (TO) is rare benign disease of unknown cause, in which multiple cartilaginous or bony submucosal nodules project into the trachea and proximal bronchi. The nodules usually spare the posterior wall of the airway because they are of cartilaginous origin, while the posterior wall of the airway is membranous. This is as opposed to tracheobronchial amyloidosis, which does not spare the posterior wall. It usually occurs in men around their fifth decade of life, as opposed to tracheobronchial papillomatosis due to HPV infection, which usually occurs in younger patients. TO can cause airway obstruction, bleeding and chronic cough. Treatment involves the use of bronchodilators, and physical dilatation by bronchoscopy. The patients are also more prone to post-obstructive pneumonia and chronic lung infection in severe cases. ==Differential diagnosis== The differential of TO includes amyloidosis, which is typically circumferential, papillomatosis, though this usually occurs in younger patients and can cause lung cavitation when disseminated, Wegener's granulomatosis, though this is circumferential as well and often involves distal lung cavitation as well. Relapsing polychondritis can also spare the posterior wall, though it is not typically nodular in appearance. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tracheobronchopathia osteochondroplastica」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
