[A case of acute hyaline membrane pneumopathy in a 3-month-old infant].

The authors discuss the anatomoclinical case of an infant 3 months and 2 weeks old, presenting a clinical picture of interstitial pneumonia, in shock. Microscopic histologic examination of the lung revealed a lung disease with hyaline membranes, an unusual entity after the neonatal period. The authors assume the formation of hyaline membranes to be due to prolonged shock and the inadequate alveolar surfactant.
