Primary osteosarcoma of the parotid gland.
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.
