Abstract
Stewart-Treves syndrome is a relatively rare malignant tumor. It develops in chronic lymphedema of the upper extremities after treatment for breast cancer. We report here an additional case of a 55-year-old female.
Twenty-two years ago, she was treated with mastectomy and axillary lymph node dissection and radiotherapy for a left breast cancer. After that she had chronic lymphedema of the left upper extremity. One month before admission, she noticed a subcutaneous nodule on left cubital region. A biopsied specimen from the lesion showed angiosarcoma and the cells were positive for CD31 and CD34 immunohistochemically. The patient received a forequarter amputation. But, the tumor cells were found to have invaded to the stump, and she received radiotherapy. She is under careful follow up now. [Skin Cancer (Japan) 2004; 19: 178-180]
