[Giant cell fibroblastoma. Apropos of 2 cases]

Two cases of giant cell fibroblastoma (GCF) are reported. One presented as cervical tumor in a 11 year old child and the second localized in axillar region of 14 year old boy. Histologically both showed a typical distinctive appearance of this entity when focal fusocellular cells arranged in a storiform pattern was also constated in one. The immunohistochemical and ultrastructural study ruled out a vascular origin. The clinical and pathological findings suggest that CGF represent a juvenile form of dermatofibrosarcoma protuberans.
