Exogenous lipoid pneumonia.

Abstract

Although a rare form of nonresolving pulmonary infiltrate, exogenous lipoid pneumonia is a great mimicker. It often is mistaken for bacterial pneumonia or cancer. Many cases have been diagnosed only by open lung biopsy or other invasive procedures. Depending on the type of lipid ingested and the degree of inflammation that occurs, damage to the lung can be little to none or can fulminate to necrosis and hemorrhage. Symptoms may range from none to respiratory failure. In the case presented, the patient was ingesting Vaseline Intensive Care Lotion and baby oil as laxatives. This information was elicited only after diagnosis was made by open lung biopsy.
