Abstract: (9084 Views)
Osteoid osteoma is a unique benign primary bone tumor that may present in the metaphyseal diaphyseal areas of the short tubular bones and has also been reported in the carpal bones. It occurs in the first two decades of life. The classic history is bone pain, often relieved by aspirin. The clinical appearance is local swelling and tenderness. The typical radiographic appearance is very characteristic: an eccentric area of cortical sclerosis, frequently with a radiolucent nidus. The lesion does not exceed 1 cm in diameter. The use of a bone scan may be helpful diagnostically, as are the CAT scan and tomography. Doyle et al described seven cases of osteoid osteoma with a prolonged delay in diagnosis, but reported an excellent cure rate following excision. The carpus is not unusual as a site for this tumor, especially the scaphoid. Treatment is windowing with curettage of the tumor nidus. The use of a dental drill to window the phalanx and expose the nidus is very helpful. Removal of the entire nidus is permanently curative, but if a portion of the tumor is missed, prompt recurrence of the symptoms is the rule.
