Deskripsi
Abstract Pulmonary alveolar proteinosis (PAP) can be due to primary autoimmune and secondary causes, including e‐cigarette, or vaping, product use‐associated lung injury. We present a 33‐year‐old male presenting with PAP and a history of vaping. Serum anti‐granulocyte‐macrophage colony‐stimulating factor antibodies were present. Vitamin E (VE), but not VE acetate, was detected in bronchoalveolar lavage. This is the first report of potential association between vaping and autoimmune PAP.
