Abstract
Exogenous lipoid pneumonia is a rare entity with non-specific clinical presentation. Early diagnosis is key to prevent pulmonary fibrosis in cases of chronic exogenous lipoid pneumonia . Here, we present the diagnostic process in a 51-year-old female with chronic cough and yellow sputum, no fever nor signs of infection. The computerized axial tomography scan showed alveolar infiltrates in both lungs. We performed a bronchoalveolar lavage and collected a yellowish material, but no clear result were obtained from its analysis. Cryobiopsy of lung tissue was key for the diagnosis of exogenous lipoid pneumonia . This may be related to the chronic anorexia nervosa that the patient suffers, associated with purgative habits. After identifying the cause of the symptoms, the patient is recovering, changing her habits, and has no cough nor sputum.
