Secondary Organising Pneumonia Caused by Denosumab.

Introduction: Organising pneumonia belongs to diffuse interstitial lung diseases; we distinguish the cryptogenic organising pneumonia, which is idiopathic, from the secondary organising pneumonia caused by drugs or a defined cause. Denosumab is a human monoclonal antibody, rarely inducing adverse pulmonary effects.

Case Description: A 57-year-old female patient was admitted to our chest clinic for acute respiratory distress.
