Primary osteogenic sarcoma of breast

Abstract

A 60-years-old lady presented with a firm to hard mass in right breast. She was investigated with a mammogram and ultrasound which showed a mass of indeterminate nature with extensive calcifications. An ultrasound guided core biopsy of the mass was performed which was reported as a sarcomatous mass and excision biopsy was requested. Excision biopsy concluded that the mass was an osteogenic sarcoma in the background of a phyllodes tumor. Patient underwent a definitive mastectomy two weeks later.
