There are 4 main types of emphysema: proximal acinar emphysema (including the centriacinar emphysema seen characteristically in cigarette smokers and the focal centriacinar emphysema seen in pneumoconiosis); panacinar emphysema, characteristically found in [alpha]1-antitrypsin (protease) deficiencies; distal acinar (paraseptal) emphysema, characteristically seen in young adults with spontaneous pneumothorax, or in association with centrilobular emphysema; and finally airspace enlargement with fibrosis (also termed scar, irregular, or paracicatricial emphysema).
