Giant cell tumor of the frontal bone in a girl: case report

A 2-year-old female presented with a rare case of recurrent giant cell tumor affecting the frontal bone. She had already undergone partial removal twice at the ages of 14 and 18 months. The tumor was located in the frontal bone, expanding to the ethmoid and orbital bones, and invading the frontal base dura mater. The tumor was totally removed including the surrounding bone and frontal base dura mater. No local recurrence and metastasis were observed at 18 months after the last operation. Most giant cell tumors occur in the epiphyses of long bones and are rare in the cranio-facial bone. These tumors usually affect young adults and few pediatric cases are reported.
