摘要Dermatofibrosarcoma protuberans (DFSP) is a poorly differentiated interstitial tumor that originates from the dermis.It occurs predominantly in the 20-50-year-old males.DFSP generally presents as local pink plaques or nodules and subsequently develops into nodular masses accompanied by infiltrative growth to the surrounding tissue,including muscle and bone.1 The predilection sites are mainly the trunk (50％-60％),upper limb (25％),and head and neck (10％-15％).Although rarely metastatic,DFSP is frequently followed by a significantly high rate of regional recurrence due to indolent subcutaneous tissue spread.Wide excision is suggested to be the principal therapeutic measure of DFSP2 The difficulties of resection and reconstruction are relatively increased compared with other parts because of the low thickness of the skin and subcutis in the chest wall and because DFSP is more likely to invade bony structures.We herein summarize and report our experiences with wide excision and local reconstruction of the chest wall DFSP according to its own characteristics.
