To reiterate, the hallmark of DAD is hyaline membrane formation.[1] There is an similar process which occurs in newborns called hyaline membrane disease, although the preferred term is surfactant-deficiency disorder, that also has the formation of hyaline membranes.[8] This disorder typically develops due to prematurity, especially when the infant is delivered prior to 36 weeks since surfactant doesn't start being produced till 35 weeks gestation.[8] The lack of surfactant causes alveolar collapse and subsequent damage to the epithelial lining of the alveoli, causing the same path of damage described in the above section.
