Objectives:
To report a case of adenoid cystic carcinoma of the external auditory canal with petrous involvement.
Material And Methods:
A 50-year-old woman was referred to our department for the management of a necrotizing external otitis. Computed tomography and biopsy revealed an adenoid cystic carcinoma of the external auditory canal.
Results:
The patient was treated by complete surgical excision. A radiation therapy completed the treatment. Follow-up time was 19 months without evidence of recurrence. Adenoid cystic carcinoma of the external auditory canal is a rare tumor. It's a special type of carcinoma developing from the ceruminous glands. Histogenesis is difficult and unsettled. The most important survival factor is removal of the tumor with histologically free margins.
Conclusions:
Lack of specific clinical and radiological signs makes the diagnostic challenging. The adenoid cystic carcinoma is a rare neoplasm of the external auditory canal. An initial aggressive wide "en bloc" surgical resection is mandatory.
