title: Recurrent cholesteatoma with massive extension to temporoparietal scalp: case report and literature review.
abstract: BACKGROUND
  Cholesteatomas are locally destructive collections of epithelial debris arising from temporal bone squamous epithelium. Recurrences may occur after removal and are typically located within the temporal bone.
  
  
  OBJECTIVE
  This study aimed to report a case of a massive, recurrent cholesteatoma with extension to temporoparietal scalp in a 37-year-old woman.
  
  
  METHODS
  Case report with literature review.
  
  
  RESULTS
  The patient underwent complete excision of a well-circumscribed left temporal mass, intraoperatively identified to arise from the middle ear and to contain keratin debris.
  
  
  CONCLUSIONS
  We report a case of recurrent cholesteatoma with massive extension to temporoparietal scalp. Clinical suspicion of recurrent cholesteatoma should remain in the differential diagnosis of temporal mass with prior history of cholesteatoma.
