Breast sarcoma refers to a relatively heterogenous group of rare breast tumors which can include:

• angiosarcoma of the breast
• pleomorphic sarcoma of the breast
• fibrosarcoma of the breast
• myxofibrosarcoma of the breast
• leiomyosarcoma of the breast
• primary osteosarcoma of the breast

Epidemiology

As a subgroup, they comprise 0.5-1% of all breast neoplasms . They tend to present at a younger age than ductal or lobular carcinomas (mean 45 years).

Pathology

They characteristically show haematogenous metastases with nodal metastases being rather rare.

Associations

• prior chest wall irradiation
• some breast sarcomas - malignant phyllodes tumors - can develop from phyllodes tumors
