Abstract
A 79-year-old woman was seen at the hospital because of a left breast tumor. A2.0×1.5cm tumor in the AC area and a tumor 1.0cm in size in the AB area which were painful and elastic hard were palpated. Ultrosonography revealed a 1.7×1.6×0.8cm relatively discrete echo with heterogeneous inside in the AC area. Mammography visualized three tumorous shadows, 1.7×1.2cm, 1.0×0.7cm, and 1.0×0.9cm in size, respectively. Biopsy was performed for the tumor in the AC area and angiosarcoma of the breast was diagnosed. A left simple mastectomy was performed. Three were metastatic lesions, 0.7×0.5cm in size in the AB area and 0.9×0.7cm in size in the B area. In the A area, a 0.3×0.2cm metastatic lesion which had not been confirmed by the mammogram was also noted. There have been no signs of local recurrence nor metastasis, as of 6 months after the operation.
Angiosarcoma of the breast is very rare and has a poor prognosis, as only two survivors for 5 years have been reported out of 35 patients seen in the Japanese literature. This paper presents our experience with angiosarcoma of the breast with metastases to subcutaneous fat tissues of the homolateral breast.
