Peripheral facial nerve palsy is an infrequent but well-recognized clinical presentation encountered by primary care and emergency department physicians. Risk factors include diabetes mellitus (DM) and hypertension, both of which are also associated with an increased risk of cerebrovascular accident, which is a critical consideration in the differential diagnosis [1]. Prompt and accurate differentiation between central and peripheral etiologies is crucial in the initial evaluation of facial palsy. Notably, approximately 5% of cases may be secondary to neoplastic processes, whether benign or malignant [1].
Small cell carcinoma of cervix (SCCC) is a rare and aggressive high-grade neuroendocrine tumor [2]. Neurologic manifestations due to brain metastases from neuroendocrine cancers of the cervix are extremely rare, with no prior reports involving the facial nerve [3].
We report a unique case in which peripheral facial nerve palsy was the initial clinical manifestation of SCCC. This case highlights the importance of maintaining a broad differential diagnosis and underscores the pivotal role of a comprehensive history and physical examination as part of a systematic and holistic approach when evaluating patients presenting with facial nerve palsy.
