Metastatic carcinoma of the external auditory canal (EAC) is extremely rare. Herein, we report the first case of a patient with metastasis of parotid adenocarcinoma to the EAC. Clinicians should include it in the differential diagnosis of tumors of the EAC. In patients with parotid carcinoma, a physical examination of the entire head and neck, including the EAC, should be performed before surgery.
