Maxillary metastasis of osteosarcoma

Osteosarcoma, either primary or metastatic, rarely involves the jaws. Though only a few cases of mandibular metastasis of osteosarcoma have been reported, only one case of et al maxillary involvement (Singh, 1978) has been reported. A case of 21 year old boy with metastasis of osteosarcoma to the right maxilla from primary osteosarcoma of the left femur is presented. The patient complained of pain and swelling in the left maxillary region which was earlier diagnosed as maxillary sinusitis on the basis of Water's sinus radiograph in a medical hospital. Further radiographic examination with the panoramic and intraoral periapical radiographs done by us and later by fine needle aspiration cytology led us to diagnose a secondary deposits of osteosarcoma.
