Stewart-Treves syndrome is a malignant angiosarcoma that arises in a limb with long-standing lymphedema, most famously after breast cancer treatment with lymph node removal. Because of this specific association, the statement that angiosarcoma is also known as Stewart-Treves syndrome is correct in this context. Angiosarcoma originates from endothelial cells lining blood vessels (and lymphatic channels), making it a malignant vascular tumor. It is not benign, it can occur in the setting of chronic lymphedema, and it does not originate from melanoma cells.
