Objectives: Bullous pemphigoid has previously been linked to radiotherapy, but here we report the first case of MMP suspected to be a consequence of RT.
Methods: The patient described is an 85-year-old male who underwent RT to treat squamous cell carcinoma of the palatine tonsil. Shortly after therapy, the patient developed blisters with worsening dyspnea and dysphonia.
Results: This patient was successfully treated with a combination of oral immunosuppressants and surgical intervention.
Conclusion: This incident underscores that not all episodes of mucosal ulceration following radiation are a result of mucositis and MMP should be considered in the differential.
Level of evidence: Level 4.
Keywords: bullous pemphigoid; mucous membrane pemphigoid; radiation therapy; supraglottic stenosis.
