Disseminated angiosarcoma of the dialysis fistula in 2 patients without kidney transplants.

Angiosarcoma of the dialysis fistula is a rare occurrence. Of the 8 cases of angiosarcoma of the dialysis fistula reported in the literature, all occurred after kidney transplant and long-term immunosuppression therapy. We report 2 cases of disseminated angiosarcoma of the dialysis fistula in hemodialysis patients without concurrent kidney transplants or immunosuppression. Both patients presented with symptoms of pain and bleeding at the site of the thrombosed fistula. Clinicians should be aware that angiosarcoma of the dialysis fistula can occur in patients without kidney transplants.
