Definition

A tumor composed of malignant cells with endothelial differentiation.

Clinical Features

  • Incidence

    Angiosarcoma (AS) of the breast is a rare disease accounting for about 1% of all soft tissue breast tumors.

    It may present as primary AS, without previous history of mammary carcinoma or any associated factor, or as secondary AS, most commonly associated with previous breast irradiation.

    Primary AS represents <0.05% of all primary breast cancers.

    Secondary AS presents a median of 10.5 years after radiotherapy for breast cancer. In those patients undergoing breast conserving surgery with adjuvant radiotherapy, the estimated incidence of radiation-induced AS is 0.05–0.3%.

    AS rarely occurs after mastectomy with axillary dissection without irradiation and during pregnancy.

  • Age

    Primary AS more frequently affects young and middle-aged women (median age 30–55 ys).

    Secondary AS presents in older women (median age 67–71 ys) after radiotherapy for breast cancer.

  • Sex

    Rare cases of AS have...
