Chronic Pulmonary Aspergillosis Complicating Bronchial Atresia

Figure 2

(a) At scanning magnification (20x; hematoxylin and eosin), marked emphysema is present in association with patchy fibrosis and irregular and markedly ectatic bronchioles filled with inspissated debris, consistent with CLH. (b) At medium power (100x; hematoxylin and eosin), amorphous and partially calcified masses fill ectatic bronchioles, accompanied by numerous branching hyphae consistent with Aspergillus (inset; 600x; Gomori methenamine silver), findings that are diagnostic of aspergilloma.
