[Giant cell fibroblastoma recurring as dermatofibrosarcoma. A pediatric case report].

Giant cell fibroblastoma (GCF) is a rare neoplasm occurring mostly in children. It has a tendency to recur locally after treatment. We report a new case noticed in an five year-old child who developed recurrence a first time three years later with the picture of GCF and at a second time with the picture of dermatofibrosarcoma protuberans 17 months later.
