Abstract
We report a case of a 47-year-old male with external auditory canal cancer with difficult diagnosis, successfully treated with chemoradiation therapy. The patient was treated for 5 years as cholesteatoma in another hospital. He presented a right auricular mass and bad smell. The size of the giant tumor mass was 10cm×6cm with a papillary surface. The right cervical lymph nodes were palpable. The diagnosis from the biopsy was squamous cell carcinoma (SCC). Because the tumor invaded the right internal carotid artery and skull base, the patient was treated with chemoradiation therapy. The therapeutic effect was Complete Response (CR) and the tumor has not relapsed for 2.2 years.
