Abstract:
Four cases of primary osteosarcoma of the parotid gland, where these tumors rarely occur, are presented. This neoplasm may arise after radiation therapy, but the majority arise de novo. As a group, extraosseous osteogenic sarcomas are aggressive and lethal. Patients with these tumors have an average 5-year survival rate of 15.6%. Of the four patients reported on two died within 6 months to 3 years, one has lung metastases, and one has been lost to follow-up.
