title: [Multiple reoperation of recurrent maxillofacial huge dermatofibrosarcoma protuberans].
abstract: OBJECTIVE
  To Summary the experience of surgical treatment for many times in 1 case of maxillofacial huge dermatofibrosarcoma protuberans.
  
  
  METHODS
  The patient was diagnosed with dermatofibrosarcoma protuberans according to the pathological examination. From 2004 to 2011, the patient underwent extensive surgical resection, Mohs micrographic surgery(MMS) and free flap grafting method as surgical treatment for many times, and was closely followed-up after operation.
  
  
  RESULTS
  The tumor was completely removed in each operation, with wound skin graft survived. But relapse occured repeatedly, recurrence interval was from 7 months up to five years and eight months,recurrence interval gradually extended, all of the recurrence occurred at Mohs microsurgery cut edge.
  
  
  CONCLUSIONS
  Eexpanded resection is the preferred treatment for the early stage maxillofacial huge dermatofibrosarcoma protuberans. For advanced stage tumor, expanded resection should be combined with Mohs microsurgery. Free flap grafting was suggested in primary repair insteading of myocutaneous flap. At the same time, postoperative assistant radiotherapy, strengthen follow-up and early intervention were suggested.
