Angiosarcoma of the Breast: A Case Report

Primary angiosarcoma of the breast is extremely rare that accounts for 0.04 % of all malignant breast tumours usually occurring in the third to fourth decade and occurs almost exclusively in the female breast, with only five cases of male breast angiosarcoma reported in the literature. The prognosis is usually poor and has a high mortality rate. Mastectomy followed by adjuvant chemotherapy is the treatment of choice. We report a case of a 34-year-old woman presented with an ill-defined lump in her left breast for 3 months. The patient underwent a mastectomy. Histopathological examination revealed to be high grade angiosarcoma. Immunohistochemical analysis showed the tumour cells expressed CD34 and CD31. The diagnosis of high grade angiosarcoma was confirmed. The patient is on chemotherapy.
