[A case report of angiosarcoma of the breast]

The patient was a 24-year-old female, and had received 7-40 mg of prednisolone per day from the age of 19 because of SLE. The tumor occupied almost the entire right breast with a blue-red discoloration of the skin. Histological examination of the tumor disclosed angiosarcoma and a standard radical mastectomy was performed. No metastasis was seen in the regional lymph nodes. The patient received adjuvant chemotherapy with actinomycin D and remained well 26 months after the operation.
