Abstract
|
|
|
|
Osteoid osteoma is a benign osteoblastic lesion which has been reported in almost every bone of the human body, especially in the shaft of long bones. Most commonly occurring locations are in the femur, tibia and spine, while ethmoidal bone is the rarest sites of involvement. It is usually seen in the second and third decades of age and a male preponderance has been noted. Clinical features of this tumor are an intermittent vague pain, gradually increasing in severity, with nocturnal paroxysm. This pain responds characteristically to aspirin treatment. Histologically, the nidus is sharply delineated from the surrounding, variably thick layers of dense bones and has no reports of malignant transformation. The treatment of choice appears to be en bloc resection. Recently, the authors experienced a case of ethmoidal osteoid osteoma, which was removed with intranasal endoscopic approach. Hence, we report a rare case with a review of literature.
