LID - 13030/qt4xf465w6 [pii] AB - We report a case of nivolumab-induced lichen planus (LP) reactivation that was previously in remission following chemotherapy for non-smallcelllung cancer (NSCLC). Chemotherapy-induced immunosuppression allowed for complete resolution of the patient's pre-existing LP, a T-cell mediatedautoimmune process. When the patient was switched to nivolumab immunotherapy owing to progression of NSCLC, PD-1 inhibition led to an overwhelming T-cell response that seemed to have provoked a severe LPreactivation. Although lichenoid reactions have been reported with nivolumab, to our knowledge, this is the first reported case of nivolumab monotherapycausing LP reactivation in a patient with a strong personal and family history of the disease that was previously in remission after chemotherapy.
