We describe the clinical, radiological and histological findings of patients with COVID‑19-associated acute respiratory distress syndrome who later developed severe organising pneumonia including longitudinal follow-up. Our findings may have important implications for the therapeutic modalities in the late-phase of severe COVID‑19 and might partially explain why a subgroup of COVID‑19 patients benefits from systemic corticosteroids.
