Primary osteosarcoma of the breast

Abstract

A 58-year-old female with a primary osteosarcoma of the breast (POB) is presented here. The diagnosis was based on the characteristic histological picture and on the immunohistochemical results. The possibility of the secondary lesion from a primary skeletal osteosarcoma or direct extension of an osteogenic sarcoma arising from nearby ribs or the sternum was excluded. Approximately, 150 cases of POB had been reported in the literature with tumor size affecting survival. The diagnosis needs to be made as early as possible to improve the survival of this disease.
