As the use of ICIs expands, prompt identification and management of especially severe and life-threatening irAEs are crucial. We report a case of grade 4 steroid-refractory immune-related mucositis in a 60-year-old male treated with pembrolizumab following complete resection of stage IIIC melanoma. The patient received seven courses of adjuvant pembrolizumab without adverse events until 2 weeks after the seventh dose, when he presented with acute respiratory distress, dysphagia, and dyspnea. Examination revealed significant throat swelling and mucosal edema. Despite initial treatment with high-dose steroids, the patient's condition deteriorated, and he was admitted to the ICU for intubation and close monitoring. Infliximab was administered for steroid-refractory mucositis, resulting in rapid symptom resolution and successful extubation 5 days later. This case highlights the challenges in managing severe steroid-refractory irAEs. The rapid response to infliximab suggests the benefit of early intervention with alternative immunosuppressive agents in severe irAEs.
