title: Adenoid cystic carcinoma of the external auditory canal.
abstract: This is a rare case of a young male with biopsy proven adenoid cystic carcinoma of the external auditory canal who underwent excision of the lesion with superficial parotidectomy sparing the facial nerve. Histopathology showed perineural invasion, which is a diagnostic hallmark of adenoid cystic carcinoma. Clinical examination, chest X-ray and CT scan showed no signs of recurrence or metastasis 2 years postoperatively.
