We report a case of a 59-year-old Japanese man with a black tumor on his right sole with satellite lesions. We diagnosed it as malignant melanoma (pT4aN0M0, stage III) . In December, 1997 he received wide resection and excision of the right inguinal lymph nodes. 3 courses of DAV-Feron chemotherapy were performed. In August, 1991 there was repeated local recurrence of in-transit lesions. We did simple excision and performed chemotherapy. 4 years and 6 months after the operation, the metastases were limited to in-transit lesions and evidence of distant metastasis was not noted.

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]
