title: [Osteoid osteoma of the ethmoid bone (author's transl)].
abstract: Osteoid osteoma can be distinguished from compact osteoma by the presence in its centre of a cavity (nidus) which is distinctly visible on tomography or CT scans. Contrary to osteomas, osteoid osteomas are rarely found in facial sinuses. The authors report on one exceptional case located in the ethmoid bone and review the clinical and anatomicopathological features of this benign tumour.
