a) Haematoxylin and eosin stained view (x10) of the biopsy performed at 5.5 years of age showing mild type II pneumocytes hyperplasia, diffuse septal thickening with rigid septa but without fibrosis, and few intra-alveolar macrophages without pulmonary alveolar proteinosis. b) High-resolution computer tomography of the chest at 26 years of age revealing a diffuse parenchymal lung disease with ground-glass opacities. c) Haematoxylin and eosin stained view (x10) of the biopsy performed at 26 years of age showing a similar appearance with mild type II pneumocytes hyperplasia and diffuse septal thickening with rigid septa superimposed with fibrosis.
