CONTEXT:
Adenoid cystic carcinomas are the most common of the glandular malignancies found in the external auditory canal. It is unclear however whether they arise from the ceruminous glands or from ectopic salivary tissue or from perineural spread from the adjacent parotid gland. Moreover, its histologic and biologic properties are similar to those of its counterpart in the salivary glands, making it more difficult to ascertain its origin.

OBJECTIVES:
1. Come up with the possible origin of the tumor (a primary EAC tumor or local spread from the parotid gland).
2. Present a literature review of this type of carcinoma and correlate it with the case.
3. Present the plan of management.

STUDY DESIGN: Case Report

STUDY SETTING: Jose R. Reyes Memorial Medical Center

STUDY POPULATION: 34 year old male
