 Ceruminous adenoma is an extremely rare benign tumor arising from ceruminous glands in the external auditory canal(EAC). A 76-year-old woman presented to our department with a right earache and otorrhea. Physical examination revealed a neoplastic lesion in the anterior part of the right EAC. Fine-needle aspiration biopsy was performed;however, an insufficient number of specialized cells were present in the pathological samples to afford a diagnosis. The EAC lesion was surgically resected under local anesthesia. The pathological findings showed ceruminous adenoma with a pseudoinfiltrative pattern. Regular follow-up is needed owing to the possibility of local recurrence. There was no evidence of recurrence at the two-month follow-up.
