Sarcoma of the Breast: A Rare and Heterogeneous Entity.

Breast sarcomas are a rare and pathologically diverse group of malignancies. They can arise de novo or in a previously irradiated field and tend to have poor prognostic outcomes. Given their rarity and the tendency to combine the various histologies in single analyses, data related to management and prognostic outcomes are somewhat limited. Surgical resection remains the mainstay of treatment with the intention for wide-margin resection, except in the case of radiation-associated angiosarcoma, where radical resection is associated with improved local control. Multidisciplinary treatment is common and is ideally undertaken at a high-volume sarcoma center to optimize outcomes.
