Primary angiosarcoma of the breast

Breast cancer is increasing and is the most common cancer among females in Brunei Darussalam. Most are ductal carcinoma. We report a case of a 40-year-old woman who was diagnosed with primary angiosarcoma of the right breast, a rare condition. To the best of our knowledge this is the only reported case in Brunei Darussalam. She underwent lumpectomy followed by mastectomy as the resection margins were not clear. No adjuvant therapy was given because the size of tumour was small, there was no residual tumor in mastectomy specimen and she had no distant metastasis.
