Low magnification H&E histology illustrates the transition from lung tissue to bulla (a) (magnification 25x). The peripheral lung tissue shows a fibrotic collaps of the secondary pulmonary lobules (b, EvG stain, magnification 40x). At higher magnification, a prominent peribronchiolar fibrosis as well as small granulomas with giant cells (c, magnification 40x, and d, magnification 60x) can be appreciated
