title: Dermatofibrosarcoma protuberans recurring as a hybrid dermatofibrosarcoma/giant cell fibroblastoma in an adult: a case report.
abstract: We report the case of a 44-year-old man who presented with a new area of nodularity within his scar five years after excision of a dermatofibrosarcoma protuberans (DFSP). A wide local excision was performed for suspected DFSP recurrence. Histology revealed recurrent tumour showing combined histological features of DFSP and giant cell fibroblastoma (GCF). We present this case to highlight the potential diagnostic pitfall of DFSP recurring as giant cell fibroblastoma and as further evidence that DFSP and GCF are manifestations of the same disease spectrum.
