Abstract
We report an extremely rare case of bilateral primary carcinoma of the external auditory meatus. A 50-year-old man suffered 1 month from left-ear discharge and otalgia. Examination revealed a tumor of the left ear canal and a biopsy showed well-differentiated squamous cell carcinoma. The patient underwent 60 Gy radiotherapy and left subtotal temporal bone resection. A tumor with irregular swelling of the right external canal was found 8 months after the first diagnosis. Biopsy of the right external canal confirmed the same squamous cell carcinoma. Genetic examination that the carcinoma of the right ear was probably not a metastatic from the carcinoma of the left ear.
