Bronchiolitis obliterans organizing pneumonia following a jalapeño grease fire.

Abstract

Bronchiolitis obliterans organizing pneumonia (BOOP) is an inflammatory lung disease characterized by granulation tissue in the respiratory bronchioles, alveolar ducts and alveoli. BOOP can be caused by a number of etiologies including infection, toxic inhalation, medications, radiation, and collagen vascular disease, or it can be idiopathic. We report here a case of BOOP following inhalational exposure to a jalapeño grease fire. Capsaicin and other jalapeño-derived compounds are known causes of epithelial damage and airway inflammation but to our knowledge have never been implicated in the development of BOOP. This case adds to the growing list of exposures associated with BOOP and highlights the importance of taking a thorough exposure history in patients with lung injury of unknown etiology.
