Abstract
|
|
|
rimary pulmonary amyloidosis is a rare disorder. It can be classified into tracheo-bronchial, diffuse alveolar septal and nodular parenchymal form. Trancheobronchial amyloidosis can be further subdivided into diffuse and focal arieties.
We report a case of diffuse tracheo-bronchial amyloidosis in a 49-year old man comfirmed
by broncoscopic biopsy. He has suffered from cough and exertional dyspnea over 20 years
and recently atelectasis of fright middle and lower lobe was found on chest X-ray with
aggravation of symptom. The chest CT showed irregular thickening of tracheo-bronchial wall
with calcification in addition to collapse of right middle and lower lobe. The bronchoscopy
showed multiple variable sized submucosal nodules in lower trachea and both sides of
bronchi, and biopsy revealed amyloid amyloid deposition at the subepithelial layer. We
discussed this case with review of literature.
