An osteoid osteoma is a benign tumor which arises from osteoblasts and originally thought to be a smaller version of an osteoblastoma.
Presentation
Characterized by less than 1.5cm diameter, osteoid osteomas most frequently occur in young men in the vertebrae or in the long bones and less commonly in the mandible or other craniofacial bones.
Severe pain typically occurs at night.[1] Radiographs in osteoid osteoma typically show a round lucency surrounded by sclerotic bone.
Treatment
Pain may be relieved by aspirin or other nonsteroidal antiinflammatory drugs.
Ablation is also performed in some cases.[2][3]
