a Thickened visceral pleura and prominent subpleural fibrosis characterised by abnormal increase of elastic tissue and dense collagen (H&E, 100×). Abrupt transition to normal parenchyma is also seen. Parenchyma distant from the pleura is spared. b Elastosis of the alveolar walls (black arrow; orcein, 100×.) with a predominant intra-alveolar fibrosis (white arrow)
