Case Discussion
In addition to the alveolar inflammatory changes found with regular pneumonia, there is also the involvement of the bronchioles. Histologically, it is characterised by mild chronic patchy interstitial inflammation without fibrosis and the presence of buds of granulation tissue made of mononuclear cells, foamy macrophages, and fibrous tissue (Masson bodies) in the distal airspaces which may cause secondary bronchiolar occlusion due to extension of the inflammatory process. Hence, the reason for being previously termed bronchiolitis obliterans organising pneumonia (BOOP).
