- Abstract
An adult female ringed seal died suddenly and was subsequently examined for diagnostic purposes. The animal's lungs demonstrated mild non-collapsibility and multifocal white to yellow patches. Histopathological examination revealed multifocal pulmonary histiocytosis. Alveoli were filled with numerous foamy macrophages cytoplasm and scattered multinucleated giant cells containing cholesterol clefts. The foamy cytoplasm of the macrophages stained with oil red O stain. Further, lipid droplets within the cytoplasm were detected by electron microscopy. To the author's knowledge, this is the first case report describing the histochemical staining and electron microscopic findings associated with endogenous lipid pneumonia in ringed seal.
