title: Osteoid osteoma: 95 cases and a review of the literature.
abstract: Osteoid osteoma is a benign bone tumor occurring primarily in patients under the age of 30 yr. Bone pain at night and relief by aspirin or other nonsteroidal antiinflammatory agents is a common symptom complex. The proximal femur and spine are frequent sites of involvement, but almost any bone can be involved. If plain roentgenograms do not demonstrate the lesion, tomography or a bone scan may be helpful. Complete surgical excision is the therapy of choice with a low recurrence rate. Osteoid osteoma may present initially with symptoms suggestive of inflammatory arthritis, degenerative joint disease, neoplasm, or infection. This lesion can therefore be a difficult diagnostic problem, especially if routine roentgenograms are normal. A high index of suspicion is necessary to make the diagnosis.
