title: A cerebriform mass on the right buttock.
abstract: BACKGROUND
  Nevus lipomatosus cutaneous superficialis of Hoffmann-Zurhelle (NLCS) is a rare disorder that is characterized by tumors of mature fat cells situated within the dermis.
  
  
  OBJECTIVE
  To illustrate by a case report the clinical presentation and management of this rare condition.
  
  
  METHODS
  Wide excision of the right thigh and buttock mass was performed, and pathological material was submitted. The defect was repaired with a split-thickness skin graft.
  
  
  RESULTS
  The largest measured nevus lipomatosus, congenital type (20 x 30 cm), was removed from this patient.
  
  
  CONCLUSIONS
  Physicians should be aware of this rare tumor, which can become extremely large if untreated.
