Primary fibrosarcoma of the breast: a case report.

A primary fibrosarcoma of the breast is a rare tumor. Here we report on a case of a primary fibrosarcoma of the breast that presented as a palpable left breast mass in a 47-year-old woman. The physical examination revealed a 3 cm sized, round mass in the left upper outer breast. The mammograms revealed a 3 cm sized, partially circumscribed and partially obscured, high density mass in the upper outer quadrant of the left breast. An ultrasonogram demonstrated a 3 cm sized, ovoid, circumscribed and hypoechoic mass with peripheral increased vascularity on Doppler imaging. Surgical excision was performed and the pathology revealed a low grade fibrosarcoma.
