Summary
Squamous cell carcinoma (SCC) of the external auditory canal (EAC) is rare. This report details a unique case of bilateral SCC of the EAC secondary to radiotherapy for nasopharyngeal carcinoma.
Area of Science:
- Oncology
- Otolaryngology
Background:
- Squamous cell carcinoma (SCC) of the external auditory canal (EAC) is a rare malignancy.
- SCC of the EAC often mimics otitis externa or chronic suppurative otitis media.
- Risk factors for EAC SCC are documented in medical literature.
Observation:
- This paper presents a rare case of bilateral SCC of the EAC.
- The patient developed bilateral EAC SCC following radiotherapy for nasopharyngeal carcinoma.
Findings:
- This case represents the fifth reported instance of bilateral SCC of the EAC.
- It is the first documented case of bilateral SCC of the EAC causally linked to radiotherapy.
Implications:
- This case highlights a potential long-term complication of radiotherapy for head and neck cancers.
- Further research may be warranted to understand the specific mechanisms linking radiotherapy to bilateral EAC SCC.
- Awareness of this association is crucial for clinicians managing patients with a history of radiotherapy.
