Pulmonary yellow hyaline membrane disease. New variant in premature infants with intrahepatic cholestasis.
Two premature female infants with a new variant of pulmonary hyaline membrane disease had both received assisted ventilation with high oxygen concentrations. Postmortem examination showed straw-yellow hyaline membranes lining the terminal bronchioles and alveoli. Pneumonocytes and macrophages also contained straw-yellow pigments in the cytoplasm. These yellow membranes and pigments in pneumonocytes and in macrophages stained positively for bile and negatively for iron. Both infants had severe intrahepatic cholestasis. Cholestasis and pulmonary changes due to oxygen toxicity are believed to be the main features leading to this curious entity.
