Life-Threatening Pneumonitis Related to Docetaxel Chemotherapy

Development of pulmonary infiltrates with respiratory symptoms in patients with advanced cancer presents a diagnostic challenge. We describe a case of a patient who developed progressive respiratory failure and bilateral lung infiltrates whilst receiving docetaxel chemotherapy for advanced lung cancer. After excluding other aetiologies, he was treated for docetaxel-related pneumonitis with corticosteroid therapy. Interstitial pneumonitis is a rare complication of Docetaxel chemotherapy but needs to be recognised and treated early, as it is associated with high mortality rates. We describe the presentation, differential diagnoses and possible mechanisms associated with drug-related pneumonitis
