Fibrosarcoma of the breast is a type of malignant stromal sarcoma that rarely occurs as a primary tumor within the breast.
Pathology
A fibrosarcoma is composed of immature mesenchymal elements surrounded by a collagenous substance. It is a type of breast sarcoma with a predominant “herringbone” growth pattern created by elongated spindle cells arranged in broad interdigitating sheets, bands, or fascicles. Some fibrosarcomas lack this classic herringbone pattern and consist instead of a more loosely structured fibroblastic proliferation.
Radiographic features
Mammography
Fibrosarcomas are often seen as a non-spiculated, dense breast mass with largely indistinct borders, although some borders may be sharp. There are no specific mammographic features to distinguish these from round breast carcinomas or non-calcified fibroadenomas 1.
