Surgical Management of a Breast Liposarcoma Arising in An Elderly Male with An Overlying Permanent Pacemaker

Liposarcomas are rare tumors. Here we present a case of a 90-year-old male who was found to have a rapidly enlarging left breast mass. PET CT imaging demonstrated a large mass arising between the pectoralis major and minor. Ultrasound guided core biopsy results reported spindle cells. Wide excision was performed with use of harmonic energy device due to the patient’s overlying pacemaker. Histologic analysis confirmed high grade dedifferentiated liposarcoma.
