Abstract

Exogenous lipoid pneumonia (ELP) is a rare (incidence 1.0%-2.5%), often under-diagnosed disease, caused by the aspiration and accumulation of exogenous lipids within the pulmonary alveoli. Various cases have been described due to inhalation of lubricants via the nasal passages and oropharynx, aspiration of mineral oils in laxatives in patients with eating disorders, application of lip gloss, occupational exposure to liquid paraffin or mineral oils ("fire-eaters", industrial use in washing of machinery, automobile workshops, plastic paints, etc.) and application of Vaseline during the insertion of nasogastric tubes and in the care of tracheotomy patients. ELP usually presents radiologically as areas of low-attenuation peribronchial consolidation and ground glass opacities, with a predominantly bibasal distribution. We present 5 cases of long-standing laryngectomy patients diagnosed with ELP who admitted using Vaseline in their tracheal stoma care.
