title: [Localized osteoplastic bronchopathy with tumoral expression, including Al amyloidosis].
abstract: We report a case concerning a 65 year old man who suffered from a drug resistant asthma and radiographically visible mass in the right lower lobe of the lung. Pathological studies demonstrated it to be "Bronchopathia Osteoplastica", involving segmental bronchi, with completed hematopoietic metaplasia. This rare dystrophic lesion was associated with localized lambda light chain amyloidosis as was proved by the immunohistochemistry. This association suggests a possible relation between amyloidosis and abnormal osteogenesis.
