BACKGROUND: Inflammatory processes are a rare cause of peripheral facial palsy. In most cases even massive infection does not lead to a loss of facial nerve function. In the literature, only 8 cases of facial paralysis associated with parotid cyst have been described. PATIENT AND RESULTS: We present a case of facial palsy caused by an inflamed cyst of the parotid gland. The patient was operated on with the diagnosis malignant parotid tumor. The pathological report showed a squamous epithelial cyst, massive lymphocytic infiltration. CONCLUSIONS: As a rule the combination parotid gland lesion and facial palsy is a sign of malignancy, clinicians should be aware that, on rare occasions, facial nerve dysfunction may result from benign parotid gland disease.
