Abstract:
Sarcomas are rare and account for approximately 1% of all malignancies. The subtype angiosarcoma is derived from vascular and lymphatic tissue and generally has a poor prognosis. Prior radiation therapy is a known risk factor for the development of angiosarcomas. We present what we believe to be the first case of an angiosarcoma arising in the epididymis in an 80-year-old man who presented with right scrotal swelling.
