Hematoxylin and eosin staining of acquired tissue specimen. a H&E staining of patient 1 showed non-specific inflammation accompanied with interstitial fibrosis with lymphocyte and plasma cell infiltration. Mild alveolar epithelial hyperplasia can be observed and red staining materials aggregated in alveolar lumen with dispersed tissue cells. b H&E staining of patient 2 showed alveolar hyaline membrane formation with large nuclei hyperchromatic cells in the alveolar space. c H&E staining of patient 3 showed alveolar epithelial and interstitial fibrous tissue hyperplasia, inflammatory exudate, foam cell aggregation and inflammatory cell infiltration in alveolar cavity. d H&E staining of patient 4 showed focal chronic inflammation with fibrous hyperplasia
