MASDEU, Martín et al. Fibrosing Exogenous Lipoid Pneumonia in a Patient with Parkinson Disease. Rev. am. med. respir. [online]. 2020, vol.20, n.2, pp.189-194. ISSN 1852-236X.

Deglutitive disorders that result from different diseases may cause aspiration episodes into the airways, determining a lung injury whose severity will depend on the material that was aspirated and the exposure time. If the aspirated agent has an oily composition, its aspiration is capable of triggering a pulmonary inflammatory reaction called lipoid pneumonia which after some time may cause irreversible parenchymal fibrosis. The case reported in this study describes a patient with deglutitive disorders and prolonged intake of vaseline as laxative. The large assymetric involvement of the lung parenchyma and the diagnostic methodology used to identify lung macrophages charged with lipids take particular importance. A review of the evidence has been carried out in that regard during the discussion of the case.

Palabras clave : Lipoid pneumonia; Macrophages; Vaseline.
