• Facial nerve
• Parotid
• Pleomorphic adenoma

Objective: To describe a case and discuss the differential diagnosis of facial nerve paresis presenting years after resection of multiple recurrent parotid pleomorphic adenoma.
Patients: Case report of a patient on immunosuppressive therapy with facial nerve weakness 3 years after last resection for multiple recurrent pleomorphic adenoma.
Interventions: Computed tomography and magnetic resonance imaging followed by surgical exploration, resection, and reconstruction.
Main Outcome Measures: Histopathologic diagnosis and treatment outcome.
Results: Final diagnosis of recurrent pleomorphic adenoma causing compression of the facial nerve at the stylomastoid foramen.
Conclusion: Facial nerve weakness caused by a benign salivary gland tumor is rare. Although alternate diagnoses must be considered, recurrent pleomorphic adenoma alone may impair facial function by impinging on the nerve in the stylomastoid foramen.
