Localized Bullous Pemphigoid Arising within Sites of Radiation in the Context of Immune Checkpoint Inhibitor Therapy

Key Points

• To explore the occurrence of localized bullous pemphigoid in areas previously treated with radiation during immune checkpoint inhibitor therapy.
• Case series analysis of patients with localized bullous pemphigoid
• Review of radiation history and immune checkpoint inhibitor use.
• Examination of skin lesions and treatment response.
• Localized bullous pemphigoid developed in all patients within irradiated skin areas.
• Concomitant immune checkpoint inhibitor therapy may play a role in this localization.
• Minimal literature previously documented these specific cases.
