Objective: To present a rare case of Adenoid Cystic Carcinoma of the external ear canal in a 73-year-old man, including its diagnosis and surgical management. : Methods Design: Case Report Setting: Tertiary Government Training Hospital Patient: One Results: A 73-year-old man who consulted due to decreased hearing on the right ear had a 4-year history of gradually enlarging mass occupying the right external auditory canal. Wide en bloc resection of the external auditory canal mass and superficial parotidectomy with facial nerve preservation was performed with final histopathology results of adenoid cystic carcinoma. Follow-up at 2 years has shown no signs or symptoms or recurrence. Conclusion Adenoid cystic carcinoma of the external ear canal is a very rare disease that can present similarly to other otologic infections. Early identification of symptoms, performance of necessary imaging, and timely biopsy are key to reducing misdiagnosis and improving the survival rate. Complete resection of the tumor with adequate margins is the recommended treatment due to its high rates for recurrence.

Meningiomas account for approximately 13 to 18 per cent of all primary intracranial neoplasms. The majority of meningioma cases develops in the supratentorial compartment with only 8 to 9 per cent occurring in the posterior fossa. Twenty per cent of intracranial meningiomas eventually develop an extracranial extension. Intracranial tumors that extend to the middle ear and external auditory canal are uncommon. The most common pathway in the temporal bone is through the jugular foramen and foramen lacerum into the parapharyngeal space. When a meningioma gains access to the temporal bone, neurological symptoms usually develop. By the time symptoms become apparent, however, the tumor is usually quite large. The presentation was unusual in that there were no demonstrable neurological signs clinically, despite the large size of the intracranial tumor and mass effect. We experienced a case of extracranial meningioma in the external auditory canal that was extended from intracranial meningioma, and which was diagnosed with biopsy and radiographic examination. In this paper, we report this case with review of literature.
