The Teaching Point

Liposarcoma is a rare breast neoplasm. The fat component of this mass seen on the mammogram and ultrasound helped to differentiate it from other malignancies such as carcinomas and other sarcomas. The presence of a solid /soft tissue component on mammogram and ultrasound and internal vascularity seen on color Doppler helped to differentiate it from benign fat containing masses. Histologic type and degree of differentiation in a liposarcoma are crucial for surgical planning and prognosis. Wide excision is the most important mode of treatment. Adjuvant chemotherapy or radiotherapy may be needed in higher grades.

Abstract
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.
