[Osteoid osteoma of zygomatic bone: Case report and literature review].Rev Stomatol Chir Maxillofac Chir Orale. 2016 Dec; 117(6):442-445.RS
Osteoid osteoma is a benign osseous tumor affecting mainly young men. Although it develops essentially in long bones, some cases occurring in face, mainly in mandible, were related. To our knowledge, only one single case was described in zygomatic bone.
A 71-year-old man consulted for a right periorbital pain evolving since months with night recrudescence. The pain was not relieved by standard analgesics. Clinical examination was strictly normal. CT scan showed a low-density bone lesion surrounded by a peripheral osseocondensation line within the body of the right zygoma with intense uptake at bone scintigraphy. The patient benefited from surgical excision of the lesion. Pain stopped immediately. Histological examination assessed an osteoid osteoma.
Zygomatic localization and late occurrence are rare concerning osteoid osteomas. Many ways of management have been reported but surgical excision remains the gold standard.
