Pulmonary Hyalinosis in Dogs

Pulmonary Hyalinosis in Dogs

1976

Pulmonary hyalinosis occurred in Beagles exposed to radon daughters with uranium ore dust. The lesion was composed of alveolar cells distended with material positive for periodic acid-Schiff (PAS) and oil red O that ultrastructurally consisted of a whorled arrangement of lamellar membranes suggestive of a storage disease. The high incidence in exposed dogs and the ultrastructural appearance suggested the material originated endogenously as a degenerative response to injury.
