Primary Breast Liposarcoma

Liposarcoma of breast is a rare malignant breast tumor. 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 benign fat -containing masses, carcinomas and other sarcomas. This is important as treatment of these varying conditions differ widely. Histologically, liposarcoma may be well differentiated, mixed or dedifferentiated (high grade). The risk of metastasis and recurrence increases with higher grade. Determination of the degree of differentiation is important for surgical planning and prognosis.
