BACKGROUND: A kidney transplant recipient inadvertently contracted donor-origin melanoma, which was found to be very advanced at presentation. Withdrawal of immunosuppression failed to induce rejection, and interferon-alpha was required. When florid allograft rejection was in progress, the allograft was removed, before it was recognized that the transplanted melanoma was not being simultaneously rejected. METHODS: Subsequent immunotherapy was required, which largely recapitulated treatment of recognized value in autologous melanoma and included interferon-alpha, use of cultured melanoma cells as tumor vaccine, pooled allogeneic cell vaccination, and adoptive immunotherapy using lymphokine-activated killer cells. RESULTS: Prolonged immunotherapy eradicated the widespread malignancy, and the patient went on to a successful second renal transplant, with follow-up of over 24 months. CONCLUSIONS: This unique case demonstrates the successful cure of advanced transplanted melanoma through the use of immunotherapy, which did not require sophisticated tumor vaccine technology, and successful retransplantation.
