[Angiosarcoma of the breast: a case report and literature review].

Sarcoma of the breast is a rare tumor (makes up 0.5 to 1% of all malignant breast tumors). In literature, only isolated cases of primary angiosarcoma of the breast were described. Secondary angiosarcomas are more frequently diagnosed in women and mostly in patients who underwent breast-conserving surgery and were treated by radiotherapy. In this article a very rare case of angiosarcoma of the breast is presented. The tumor in the breast was diagnosed after breast trauma. After surgery the diagnosis of hematoma was made. Nine months after surgery tumor spread was observed in subdermal layer, lymph nodes, and lungs. After review of histopathology slides the likely diagnosis of angiosarcoma of the breast was made. The effect of chemotherapy and radiotherapy was only partial and short. The tumor extended further to the lungs, pleura, and peritoneum. A patient from the time of diagnosis survived for 8 months. The mean survival of patients with angiosarcoma of the breast, described in literature, ranges from 13 to 22 months, and the treatment in this case most likely could not have an effect on survival of the patient.
