A very large, rapidly developing, congenital giant cell fibroblastoma in a 5‐month old infant

Giant cell fibroblastoma is an uncommon soft tissue neoplasm that occurs in childhood. It seems to be the juvenile form of dermatofibrosarcoma protuberans, which is seen less frequently in children. Only one congenital case has been reported previously. In this report, we present a 5‐month‐old girl with a rapidly and atypically growing mass located on the upper part of the right scapula. We think that our case is very interesting, because no similarly large lesion (12 cm × 10 cm × 8 cm) related to giant cell fibroblastoma has been previously reported in the published work.
