Highlights a rare case of metastatic angiosarcoma arising in the setting of chronic lymphedema due to filariasis (Stewart-Treves syndrome).
Raises awareness for angiosarcoma in chronic filarial lymphedema; extends the etiologic spectrum of Stewart-Treves syndrome.
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).
