Early Fatal Cutaneous Lower Extremity Angiosarcoma Associated with Deep Venous Thrombosis in a Renal Transplant Recipient.

Angiosarcomas are extremely rare malignant tumors of vascular origin. We describe a 63-year-old recipient after a kidney transplant who had an angiosarcoma in the lower extremity that presented after new-onset deep venous thrombosis and was not associated with any fistula. There was rapid progression to metastasis and death.
