A 70-year-old male experienced immune-related lung injury that was refractory to corticosteroid therapy following administration of pembrolizumab as first-line treatment for non-small cell lung cancer. The lung injury transiently improved following treatment with infliximab but worsened two weeks later, leading to lethal respiratory failure. An autopsy revealed organizing and acute phases of diffuse alveolar damage, which presumably reflected the primary lung injury and its re-exacerbation, respectively. The withdrawal of infliximab might be associated with the re-exacerbation of the lung injury. The present case suggests that the administration of infliximab for recurrent immune-related lung injury should be considered.
