Summary
Malignant external otitis and squamous cell carcinoma rarely occur together, especially in nondiabetic patients. This case highlights the need for biopsy in suspected malignant external otitis and considers iatrogenic induction.
Area of Science:
- Otolaryngology
- Oncology
- Pathology
Background:
- Malignant external otitis (MEO) and squamous cell carcinoma (SCC) of the external auditory meatus (EAM) typically affect the elderly.
- While sharing some symptoms like otalgia, otorrhea, and CT-detected bone destruction, concurrent presentation is rare.
Observation:
- This report details an unusual case of concurrent temporal bone cancer and MEO in an elderly, nondiabetic patient.
- The patient presented with symptoms mimicking classic MEO, underscoring diagnostic challenges.
Findings:
- Biopsy is crucial for accurate diagnosis, differentiating MEO from SCC and identifying co-existing malignancies.
- The case suggests MEO may be iatrogenically induced, as evidenced by its evolution after aural irrigation.
Implications:
- Clinicians must consider SCC in patients with presumed MEO, necessitating adequate biopsy.
- The potential for iatrogenic induction of MEO warrants careful consideration of treatment modalities like aural irrigation.
