Although nonspecific, this histopathological pattern, together with characteristic clinical and imaging features, defines cryptogenic organising pneumonia when no cause or peculiar underlying context is found. Rapid clinical and imaging improvement is obtained with corticosteroid treatment, but relapses are common after stopping treatment. SERIES “RARE INTERSTITIAL LUNG DISEASES” Edited by C.
