Extraskeletal osteosarcoma in the parotid gland: A case report

Extraskeletal osteosarcoma is a very rare tumor and accounts for 4–5% of all osteosarcomas. We describe a 47-year-old Japanese man who presented with a right parotid tumor. The patient underwent total resection with postoperative radiotherapy; however, the tumor recurred in the lung, whereupon he underwent chemotherapy and partial lung resection. After surgery, a hemorrhagic brain metastasis appeared; this tumor was extirpated to prevent bleeding into the brain, after which additional chemotherapy was administered.
