Primary osteogenic sarcoma of the ethmoid sinus: a case report.
Primary osteogenic sarcoma arising from the ethmoid sinus is an extremely rare condition. We report herein a 50-year-old female presenting with lacrimation. Computed tomography (CT) scan showed tumor calcification, which is a common feature of osteogenic sarcoma. Exploratory ethmoidectomy was performed, and histological examination confirmed the diagnosis of osteogenic sarcoma. Radiation therapy and chemotherapy failed to reduce the tumor size. The patient was finally treated by anterior craniofacial resection and orbital exenteration. Although primary osteogenic sarcoma of the ethmoid sinus is uncommon, the authors emphasize that osteogenic sarcoma should be suspected when tumor calcification was observed on CT scan and that adequate surgical resection with negative surgical margins remains the mainstay of treatment of this lesion.
