Abstract

OSTEOSARCOMA OF THE SINONASAL CAVITY IN A CHILD Rabia Bozdogan Arpaci, Yasemin Yuyucu Karabulut, Tuba Kara, Ebru Serinsoz Linke, Gulfiliz Gonlusen, Kemal Gorur, Department of Pathology, Mersin University, Mersin, Turkey; Department of Pathology, Cukurova University, Adana, Turkey; Department of Otorhinolaryngology, Mersin University, Turkey Osteosarcoma (OS) is the most common primary malignant neoplasm of bone. Only 6% to 30% of maxillofacial osteosarcomas have been detected in the first or second decade. It occurs usually in bones of the jaw and has rarely been reported in the nasal cavity or paranasal sinuses. Osteosarcomas arising in paranasal sinuses are usually high-grade malignancies. We report a rare case of an chondroblastic osteosarcoma in the nasal cavity of a 8 year-old female with clinical and histopatholgical features.
