title: Synchronous mucosal Schwann-cell hamartomas in a young adult suggestive of mucosal Schwann-cell harmatomatosis: a case report.
abstract: BACKGROUND
  Mucosal Schwann-cell hamartoma is a rare mesenchymal polyp that presents in the intestine. Despite lacking ganglion cells, it resembles a gastrointestinal ganglioneuroma.
  
  
  METHODS
  We report a case of synchronous mucosal Schwann-cell hamartomas in a young male patient, who presented with a single discrete polyp in the mid-rectum and multiple polypoid mucosal lesions in the distal rectum.
  
  
  CONCLUSIONS
  To the best of our knowledge, this is the first report of a case of multiple mucosal Schwann-cell hamartomas.
