title: A 42-year-old man with facial nerve weakness and multiple recurrent pleomorphic adenoma.
abstract: OBJECTIVE
  To describe a case and discuss the differential diagnosis of facial nerve paresis presenting years after resection of multiple recurrent parotid pleomorphic adenoma.
  
  
  METHODS
  Case report of a patient on immunosuppressive therapy with facial nerve weakness 3 years after last resection for multiple recurrent pleomorphic adenoma.
  
  
  METHODS
  Computed tomography and magnetic resonance imaging followed by surgical exploration, resection, and reconstruction.
  
  
  METHODS
  Histopathologic diagnosis and treatment outcome.
  
  
  RESULTS
  Final diagnosis of recurrent pleomorphic adenoma causing compression of the facial nerve at the stylomastoid foramen.
  
  
  CONCLUSIONS
  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.
