Angiosarcoma (AS) is an uncommon malignant neoplasm characterized by rapidly proliferating, extensively infiltrating anaplastic cells derived from blood vessels. These are aggressive tumors and tend to recur locally, spread widely with high rate of lymph node and systemic metastases. They are more frequent in skin and soft tissue, head and neck being the most common sites. Here we report a case of metastatic AS affecting lower extremity in an elderly patient on a background of chronic lymphedema due to filariasis (Stewart-Treves syndrome).
血管肉瘤（AS）是一种罕见的恶性肿瘤，其特征是由血管来源的迅速增殖、广泛浸润的间变性细胞组成。这些是侵袭性肿瘤，易于局部复发，以高淋巴结转移率和全身转移率广泛扩散。它们在皮肤和软组织中更为常见，头颈部是最常见的部位。在此，我们报告一例老年患者因丝虫病导致慢性淋巴水肿（斯图尔特-特里夫斯综合征）背景下发生的下肢转移性血管肉瘤病例。
