 External auditory canal tumors are difficult to diagnose because of the various histological findings. Herein, we report a case of ceruminous adenoma in the external ear canal. A 76-year-old male was referred to our hospital with pain in the right ear and swelling of the right external auditory wall. Fine-needle aspiration cytology could not provide a correct diagnosis, and CT showed no temporal bone destruction. However, fluorodeoxyglucose positron emission tomography showed accumulation in the right external auditory canal. The tumor was completely resected using a posterior ear incision for diagnosis and treatment. The pathological diagnosis was a ceruminous adenoma.
