title: A case report of three peripheral schwannomas attached to the Achilles paratenon.
abstract: BACKGROUND
  Schwannomas are uncommon slow growing tumours arising from the nerve sheath or Schwann cell.
  
  
  OBJECTIVE
  To report a case of multiple schwannomas arising form the achilles paratenon.
  
  
  METHODS
  A 38 year old man presented lumps on the dorsum of his leg. He was clinically evaluated, subjected to imaging studies and surgery.
  
  
  RESULTS
  3 separate lumps where removed measuring 10, 12, and 12mm. They here confirmed to be schwannomas on hitochemical staining.
  
  
  CONCLUSIONS
  A schwannoma must be considered in the differential of lumps in the lower leg. This is the first report of schwanommas associated with the paratenon. Removal of such masses is warranted to prevent local erosion.
