Core Tip

Core Tip: We report a rare case of multi-system damage induced by cancer therapy with protein 1 ligand inhibitor teriprizumab. A man with squamous cell carcinoma of oropharynx on a combination regimen of teriprizumab, docetaxel, and cisplatin developed autoimmune polyendocrine syndrome type II (APS-2) including thyroiditis and type 1 diabetes mellitus (T1DM) and Crohn’s disease (CD). This case report highlights the possibility of chronic immune toxicities and the long-term implications of cancer immunotherapy. To the best of our knowledge, this is the first reported case of concurrent atypical APS-2 (including T1DM and thyrotoxicosis) and CD in a patient receiving immunotherapy for metastatic nasopharyngeal carcinoma.
