Pediatric Cases of Recurrent Skull Giant Osteoma Misdiagnosed as Fibrous Dysplasia

Research output: Contribution to journalArticlepeer-review


Osteomas are benign mature bone tumors that typically arise in the skull. Osteomas larger than 3 cm in diameter are considered giant osteomas. Giant osteomas of the skull vault are very rare, especially in children; therefore, only a few cases have been reported in the literature. Although osteomas are usually asymptomatic, a large skull mass can cause headache, as well as esthetic disfigurement of the forehead. it can be misdiagnosed as other conditions, such as fibrous dysplasia, ossifying cephalhematoma, or other malignant bone tumors. Herein, the authors report 2 rare pediatric cases of giant osteomas mimicking fibrous dysplasia and their successful surgical excision. These cases showed good results without recurrence or complications on long-term follow-up after complete excision.
