[A case of dermatofibrosarcoma protuberans who underwent chest wall reconstruction].

Dermatofibrosarcoma protuberans (DFSP) is a slowly growing tumor that occurs in the dermis, and it has a tendency to recur repeatedly. We reported a case, 50-year-old woman, who underwent chest wall reconstruction due to recurrence of DFSP. Since the first operation for the tumor 35 years ago, she had undergone surgical procedures 30 times. We had to resect parts of the rib cartilages and the sternum because we suspected the tumor had reached to the anterior mediastinum. There has been no recurrence for 8 months since this operation. Importance of extensive resection of the tumor to prevent a recurrence and long term follow-up should be stress.
