Summary
Malignant melanoma of the external auditory canal is rare but aggressive. Early diagnosis is crucial for effective treatment, often requiring extensive surgery and careful consideration of lymph node metastasis.
Area of Science:
- Oncology
- Otolaryngology
- Dermatology
Background:
- Cutaneous melanomas demonstrate a significant increase in incidence over the past fifty years.
- Melanomas originating in the external auditory canal (EAC) are exceptionally rare occurrences.
Observation:
- EAC melanomas exhibit aggressive and often asymptomatic behavior, leading to late-stage diagnoses.
- A case involving a male patient with malignant melanoma of the left EAC is presented, initially suspected as epidermoid carcinoma.
Findings:
- The advanced stage and clinical presentation necessitated extensive surgical intervention, including lateral temporal bone resection, parotidectomy, and neck dissection for complete tumor removal.
- Literature review and analysis focus on incidence, the significance of lymph node metastases, and the role of elective neck dissection in EAC melanoma management.
Implications:
- This case highlights the aggressive nature of EAC melanoma and the importance of comprehensive surgical resection.
- Understanding the prognostic value of lymph node involvement is critical for treatment planning and patient outcomes in rare head and neck cancers.
