Primary Breast Sarcomas are rare, accounting for less than 1% of breast malignancies. The authors present a case of primary breast liposarcoma in a 58 year old female with a left palpable lump, present since four months. Following core needle biopsy, the nodule was diagnosed as well differentiated liposarcoma. She underwent conservative surgery of the left breast, without radiation therapy. The patient is currently free from any symptoms of local recurrence and metastasis 9 months after surgery.
