Primary Breast Liposarcoma.

Liposarcoma of breast is a rare breast malignancy. It accounts for 0.3% of the breast sarcomas. Subtypes of breast sarcomas are angiosarcoma (most common), liposarcoma, malignant fibrous histiocytoma, leiomyosarcoma and fibrosarcoma. We hereby report a case of liposarcoma in a 55 year old female emphasizing the imaging features that can aid in differentiating it from carcinomas, other sarcomas and benign fat containing masses. This is important as treatment of these varying conditions differ widely. Histologically, liposarcoma may be well differentiated, mixed or dedifferentiated (high grade). Risk of metastasis and recurrence increase with higher grade. Determination of the degree of differentiation is important for surgical planning and prognosis.
