title: Giant multilocular epidermoid cyst on the left buttock.
abstract: BACKGROUND
  Epidermoid cysts are the most common cysts of the skin. They are generally small and slow-growing and rarely reach more than 5 cm in diameter.
  
  
  OBJECTIVE
  We present a patient with a giant multilocular epidermoid cyst.
  
  
  METHODS
  A 75-year-old man presented with a giant, soft, painless, tumorlike mass on the left buttock that had gradually enlarged over a 12-year period. Excision of the mass from the surrounding tissue was extremely easy because of a well-defined capsule.
  
  
  RESULTS
  The 28 x 14 x 12 cm mass was totally excised. A histopathologic examination revealed that it was an epidermoid cyst.
  
  
  CONCLUSIONS
  This rare case of giant epidermoid cyst was treated successfully by local excision followed by primary closure. Dissection of the mass from the surrounding tissue was extremely easy because of a well-defined capsule.
