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. We reviewed the literature of this rare malignant tumor in kidney transplant patients.
