Benign Fibrous Histiocytoma of the Frontal Bone.

Benign fibrous histiocytoma rarely occurs in bone and may affect femur, tibia, and pelvic bone. The authors report here a patient concerning a 11-year-old girl with a 28-day history of an enlarging frontal bone mass. The tumor was excised after removal of the cortical bone and resection of the tumor surrounding the cortical bone erosion using preplasticity titanium repair. Postoperative histopathological examination analysis was consistent with a benign fibrous histiocytoma. Although a primary benign fibrous histiocytoma of the frontal bone is a rare tumor, it should be considered a potential diagnosis for any cranial tumor.
