Giant-cell fibroblastoma and dermato fibro sarcoma protuberans: The same tumoral spectrum? Report of two cases of association in children

We describe two cases of giant-cell fibroblastoma (GCF) with dermato fibro sarcoma protuberans (DFSP) component, occurring in two children in a chest wall localization. One case recurred 1 year later. The two patients were tumor-free 12 and 8 years later, GCF is a rare mesenchymal cutaneous and subcutaneous tumor reported mostly in the first two decades of life. Dermato fibro sarcoma protuberans, occurring preferentially in adults, is a rare skin tumor with a pronounced tendency to local recurrence. Some cases of association of recurrence of GFC under the form of DFSP have been reported, raising the question of a continuum between the two tumors. The treatment of choice of the two tumors is a wide local excision.
