Endogenous Lipoid Pneumonia with Special Reference to Carcinoma of the Lung

Abstract

Demonstrable fat in the lung due to the inhal- ation of mineral or vegetable oils or to fat embolism is well known. The occurrence of lipoid consolidation in which the fat was of endogenous origin and shown to consist largely of cholesterol and its esters was reported in a previous communication (De Navasquez, Trounce, and Wayte, 1951) and it was concluded that such fatty change was primarily the result of degen- eration due to chronic injury. The present study was made to investigate the incidence and mechanism of such pathological changes and to test this conclusion.
