    Facial nerve (FN) palsy, as a solitary symptom resulting from metastatic tumor is uncommon, and metastases to the external auditory canal (EAC) are even more infrequent. In this article, we report a unique case of the novo stage IV invasive lobular breast carcinoma (ILC) presenting as an EAC metastasis and leading to FN palsy as the first symptom, highlighting the importance of considering a broad differential diagnosis.
