Autoimmune pulmonary alveolar proteinosis in a patient with sarcoidosis

Abstract

Key Clinical Message Steroids used to treat sarcoidosis may induce aPAP. The cooccurrence of sarcoidosis and autoimmune pulmonary alveolar proteinosis (aPAP) is rare. In this case, aPAP merged into sarcoidosis regardless of the disease state of sarcoidosis and improved naturally. When using steroids during sarcoidosis exacerbation, attention should be paid to aPAP relapse.
