Osteosarcoma metastatic to the ovary: A case report and review of the literature

A 23-year-old black woman presented with abdominal pain of sudden onset, high fever, chills, and an elevated serum alkaline phosphatase level. Examination revealed a tender abdominopelvic mass consistent with an ovarian mass. Her medical history was significant for an osteosarcoma of the left humerus removed 7 rears earlier and excision of multiple pulmonary and chest wall metastases 7 years earlier. Exploratory laparotomy revealed a solid hemorrhagic left ovarian mass and ascites. There was no other evidence of disease. A left salpingo-oophorectomy was performed. Pathological examination of the mass showed metastatic osteosarcoma. Four months later, the patient died of widespread osteosarcoma. The clinicopathologic features of ovarian osteogenic sarcomas reported in the literature ale reviewed. Pain, fever, and elevated serum alkaline phosphatase levels may be the presenting clinical features of this rare ovarian tumor.
