title: Osteogenic sarcoma of the tongue.
abstract: A 45-year-old woman had a mass in the left side of the tongue. Histologic examination of the tumor revealed it to be an extraskeletal osteogenic sarcoma. Pulmonary metastases were seen on admission. The patient had a rapid downhill course and died. Extraskeletal osteogenic sarcomas are well-recognized albeit rare neoplasms. In a search of the literature we were unable to find a single case arising in the tongue. The electron microscopic findings are also presented.
