title: Pulmonary emphysema in a nonsmoker with normal alpha-1-antitrypsin.
abstract: Premature and rapidly progressing emphysema of the lung is unique in the absence of cigarette smoking or an inherited homozygous alpha-1-antitrypsin deficiency. We describe a young man with radiographic evidence of early onset bullous emphysema without the usual risk factors and provide a review of the alternative explanations proposed for this form of lung damage.
