Abstract

Abstract: 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. Nevertheless, the patient developed additional metastases and died 17 months after the total parotidectomy. This tumor was unique in that it arose in the parotid gland; this case provides an instructional example of an extremely rare manifestation of this type of tumor.
